Description

  The present invention relates to an assembled tire.

  As a tire to be mounted on a vehicle, there is a pneumatic tire that is mounted on a rim and is filled with air in a space between the rim. The pneumatic tire has a bead portion, a sidewall portion, a shoulder portion, and a tread portion, and the bead portion is attached to the rim.

  In recent years, tires other than pneumatic tires have also been proposed. For example, Patent Document 1 includes a non-pneumatic tire that does not fill air between the inner surface of the tire and the rim. In the non-pneumatic tire described in Patent Document 1, no carcass or the like is disposed in the tire. For this reason, it is not necessary to individually manufacture each part such as a carcass, a belt, a tread, and a bead and then assemble it into a single tire with a molding machine, so that the manufacturing is easy.

The inner side in the tire radial direction means the side toward the rotation axis in the tire radial direction. The outer side in the tire radial direction means the side away from the rotation axis in the tire radial direction. The tire circumferential direction means a direction around the rotation axis as a central axis. The tire width direction means a direction parallel to the rotation axis. The inner side in the tire width direction means the side toward the tire equatorial plane CL in the tire width direction.

The tire equatorial plane CL means a plane that is orthogonal to the rotation axis of the assembled tire and passes through the center of the tire width of the assembled tire.

  FIG. 1 is a front view of an assembled tire 100 according to an embodiment of the present invention, and FIG. 2 is a perspective view of the assembled tire 100. In FIG. 2, a part of the assembled tire 100 is cut and omitted for the sake of clarity.

  As shown in FIGS. 1 and 2, the assembled tire 100 according to this embodiment includes a tube body 3, a tube reinforcing member 7, and a tread ring 5. As shown in FIGS. 1 and 2, the tube body 3 is assembled to the outer peripheral surface of the rim 11. The tread ring 5 has a larger outer diameter than the tube body 3 and is disposed on the outer side in the tire radial direction of the tube body 3. The tube body 3 and the tread ring 5 are disposed concentrically on the rim 11.

  The tube body 3 is an annular elastic body and includes a plurality of cell tubes C1 to C8. The tube body 3 of this embodiment becomes an annular shape by disposing eight cell tubes C1 to C8 adjacent to each other in the circumferential direction.

  The eight cell tubes C1 to C8 are elastic tubes each filled with air. The eight cell tubes C1 to C8 serve as air chambers filled with air. The eight cell tubes C1 to C8 have independent air chambers. However, as will be described later, in a state where the cell tubes C1 to C8 are connected in an annular shape via the sub-valve, the air chambers of the adjacent cell tubes are in communication with each other. The cell tubes C1 to C8 are arranged on the outer side in the radial direction of the rim 11 of the wheel connected to the rotation shaft.

  The cell tubes C1 to C8 are hollow elastic bodies, and the inside thereof is filled with a gas such as air or nitrogen. The tube body 3 constituted by the cell tubes C1 to C8 has a ring shape (annular shape) as a whole. The cell tubes C1 to C8 are made of, for example, synthetic rubber such as butyl rubber, natural rubber, or the like.

  The cell tube C1 has an air valve V1. The air valve V1 is a valve that connects the inside and the outside of the cell tube C1, and a valve that serves as a passage for air when the cell tube C1 is filled or discharged from the inside. The air valve V1 is closed in cases other than taking air in and out. The rim 11 has a hole 11h corresponding to the air valve V1. The air valve V1 protrudes from a hole 11h provided in the rim 11 in a direction toward the rotation axis.

  FIG. 3 is a perspective view showing the appearance of the cell tubes C1 and C2, and FIG. 4 is a view showing a tube body 3 formed by the cell tubes C1 to C8. The cell tube C1 has an air valve V1 and sub valves V11 and V12. The cell tube C2 has subvalves V21 and V22. The sub-valve is an air valve that is provided at the end of the cell tube and communicates the air chambers between the cell tubes. That is, the cell tube C1 has three air valves (air valve V1, sub valves V11 and V12). The cell tube C2 has two air valves (sub-valves V21 and V22).

  FIG. 3 shows the cell tubes C1 and C2 in a state where gas is filled therein. In a state in which the gas is filled inside, the cell tubes C1 and C2 become a part of a ring. In this example, the cell tubes C1 and C2 have a shape of 1/8 of an annulus. For this reason, as shown in FIG. 4, the annular tube body 3 is formed by connecting the cell tubes C1 to C8 filled with gas through the sub-valve. At this time, each cell tube C1-C8 will be in the state which the air chamber of each cell tube connected to one by the sub valve. In addition, the air valve V1 of the cell tube C1 is in a state of protruding to the inside of the ring.

  FIG. 5A is a diagram showing a state before connection of the cell tubes. FIG. 5B is a diagram illustrating a state in which cell tubes are connected to each other. As shown in FIG. 5A, the cell tube C1 has a sub valve V11, and the cell tube C2 has a sub valve V22. The sub-valve V11 and the sub-valve V22 have a structure that can be fitted. If the connected sub-valves are structured to fit together, the number of parts will not increase. In this example, as shown in FIG. 5B, the outer diameter of the sub-valve V11 and the inner diameter of the sub-valve V22 so that the sub-valve V11 is not easily disconnected (not disconnected) when it is connected to the sub-valve V22. And the size is specified. The sub-valve V11 and the sub-valve V22 have the same structure as, for example, a pipe joint (coupler). The sub valve V11 and the sub valve V22 may be fixed using a nut, a screw, a caulking tool, or the like. Moreover, you may connect subvalves through the tube which is not shown in figure.

  FIG. 6 is a diagram illustrating a position where a sub valve is provided in the cell tube. FIG. 6 is a side view of the cell tube C1 as seen from the circumferential direction. In FIG. 6, the sub-valve V11 is provided at an end portion in the circumferential direction of the cell tube C1 when adjacent cell tubes are connected in the tire circumferential direction.

  As shown in FIG. 6, the sub-valve V11 is 60% or less (more preferably 40% from the inner diameter side) between the tire inner diameter side and the tire outer diameter side of the cell tube C1 at the circumferential end of the cell tube C1. %) Or less) is preferably located at the center of the valve. The same applies to the sub-valves of the other cell tubes C2 to C8.

  The arrangement of the center of the valve is obtained by filling the cell tube alone with 15 [kPa] air and determining the ratio of the maximum height SH of the cell tube cross section to the cross sectional height of the valve center. For example, if it is 60% from the tire inner diameter side, it is 0.6SH (SH × 60%), and if it is 40% from the inner diameter side, it is 0.4SH (SH × 40%).

  By providing the sub-valve at such a position, the efficiency of the work of connecting the cell tubes can be improved. In addition, in a state where the cell tubes are connected to each other, strain generated in the sub-valve due to shear deformation, torsional deformation, or the like can be reduced, and the sub-valve can be prevented from being damaged.

  By the way, in a state where the cell tubes are connected to each other, it is desirable that the air flow path be secured in one direction. For example, the flow path of air can be made into one direction by making the sub valve which connects cell tubes into a non-return valve. FIG. 7A is a diagram illustrating an example of the function of the sub-valve. FIG. 7B is a diagram illustrating an example of connection between sub-valves. As shown in FIG. 7A, the sub-valve has a valve B. Since the end of the valve B is fixed by the axis J, the valve B has a structure that can be opened and closed around the axis J. When the air pressure on the arrow Y1 side is higher than the arrow Y0 side, the valve B remains closed (the state shown in the figure), and no air flows. On the other hand, when the air pressure on the arrow Y0 side is higher than the arrow Y1 side, the valve B is opened and air flows. As the sub valve, for example, a check valve having a swing, a lift, a wafer mechanism, a core, and a ball may be used. By using the check valve, the independence of the air chamber of the cell tube can be ensured, and it is possible to more reliably travel a certain distance in an emergency such as a puncture.

  By adopting such a check valve structure in the sub-valve, when the cell tubes are connected in an annular shape by the sub-valve, as shown in FIG. 7B, the cell tubes are aligned so that the air flow path is in one direction. Connected. Although cell tubes C1, C2, and C8 are described in FIG. 7B, it is assumed that eight cell tubes C1 to C8 including other cell tubes C3 to C7 are connected in an annular shape. A tube body can be formed by connecting the eight cell tubes C1 to C8 in an annular shape.

  As shown in FIG. 7B, when air is introduced from the air valve V1 of the cell tube C1, air flows in the direction of the sub-valve V12 and the sub-valves V81 and V82 of the cell tube C8, that is, in one direction, as indicated by the arrows in the figure. Since all of the sub valves V12, V81 and V82 are check valves, air flows in the direction of the arrow in the figure, but no air flows in the direction opposite to the arrow. Similarly, air flows in one direction via the cell tubes C7, C6, C5, C4, and C3 that are not shown in FIG. 7B. Further, the air flow reaches the cell tube C1 via the sub valves V21 and V22 and the sub valve V11 of the cell tube C2. Accordingly, the plurality of cell tubes are connected in an annular shape, and the direction of the air flowing through the plurality of cell tubes is restricted to one direction via the connected sub-valve. At this time, paying attention to one cell tube, it has at least two sub-valves, and one of the sub-valves passes air to the connected cell tube and air from the connected cell tube. In addition, the other one of the sub-valves does not allow air to pass through to the connected cell tube and passes air from the connected cell tube. That is, the cell tubes are connected so that the air flow path is secured in one direction by the sub-valve.

  As described above, independence of the air chambers by the cell tubes C1 to C8 can be ensured by setting the air flow path in one direction. At the same time, it is only necessary to introduce air from one air valve V1 provided separately from the sub-valve, so that the work of filling the air is simplified compared to the case where air is individually introduced into each cell tube. be able to.

  As shown in FIG. 1, in the assembled tire 100 of this example, only the air valve V <b> 1 protrudes from the rim 11. For this reason, when the assembled tire 100 is assembled, a commercially available rim can be used as it is without drilling.

  As shown in FIGS. 1 and 2, the cell tubes C <b> 1 to C <b> 8 are surrounded by the tube reinforcing member 7 when assembled to the rim 11 of the wheel. In order to facilitate the assembly work of the wheel to the rim 11, the cell tubes C1 to C8 may each have a connection part for connecting to another cell tube in addition to the sub-valve.

  FIG. 8 is a diagram illustrating an example of cell tubes C1 and C2 provided with a connecting portion in addition to the sub-valve. As shown in FIG. 8, for example, surface fasteners M11 and M12 are provided at the end of the cell tube C1, and surface fasteners M21 and M22 are provided at the end of the cell tube C2, thereby providing a connection portion. 9 and 10 are diagrams illustrating an example of connection between surface fasteners.

  As shown in FIG. 9, the hook and loop fastener M12 is provided around the portion where the sub-valve V11 is attached at the end of the cell tube C1, and the hook-and-loop fastener M21 is provided around the portion of the cell tube C2 where the sub-valve V22 is attached. , Is provided. The surface fastener M12 has a ring-shaped protrusion, and the surface fastener M21 has a hook-shaped protrusion. Therefore, when the cell tubes C1 and C2 are connected by the sub-valves V11 and V22, the surface fastener M12 and the surface fastener M21 are brought into close contact with each other as shown in FIG. As a result, the cell tube C1 and the cell tube C2 are more strongly connected. Similarly, for the other cell tubes C3 to C8, when connecting the sub-valves at the end portions, the cell tubes can be more strongly connected by bringing the surface fasteners into close contact with each other. By connecting the cell tubes with the sub-valve and connecting the end portions of the cell tubes with the hook-and-loop fastener, it is possible to prevent the cell tube from rotating around the sub-valve even if the connected cell tube is moved. .

  In the actual assembly work, adjacent cell tubes C1 to C8 before being filled with air are connected to each other by a sub valve (or a sub valve and a hook and loop fastener), and the tube reinforcing member 7 and the wheel rim are connected. The cell tubes C <b> 1 to C <b> 8 are introduced into the tube reinforcing member 7 from the gap with the tube 11. Thereby, cell tube C1-C8 can be arrange | positioned easily and appropriately. The cell tubes C1 to C8 are introduced into the tube reinforcing member 7 through the gap between the tube reinforcing member 7 and the rim 11 of the wheel one by one, and the cell tubes are connected to each other within the tube reinforcing member 7 by sub valves (or sub valves and You may connect by a hook-and-loop fastener.

  If the inside of the connected cell tubes C <b> 1 to C <b> 8 is filled with air, the annular tube body 3 can be disposed inside the tube reinforcing member 7. By temporarily fixing the connecting portion, the assembling work can be performed efficiently.

  Instead of the hook-and-loop fastener, each cell tube may be provided with a snap button, a clasp, a hook or the like having a recess at one end of the two cell tubes and a protrusion at the other end as a connecting portion.

  11A and 11B are diagrams showing the structure of a sub-valve that can be housed inside the cell tube. FIG. 11C is a diagram showing a state before the cell tubes are connected to each other using the subvalve shown in FIGS. 11A and 11B. FIG. 11D is a diagram showing a state in which cell tubes are connected to each other using the subvalve shown in FIGS. 11A and 11B. FIG. 11E is a diagram illustrating a state in which the sub valve illustrated in FIGS. 11A and 11B is connected to another sub valve. 11A, FIG. 11B, and FIG. 11E are cross-sectional views of the sub-valve V22a of the cell tube C2 cut by a plane that includes the central axis along the connection direction with other sub-valves. 11C and 11D are diagrams illustrating an example in which cell tubes are connected to each other by the sub valve V11 of the cell tube C1 and the sub valve V22a of the cell tube C2.

  In FIG. 11A, the sub valve V22a protrudes from the end of the cell tube C2. The sub valve V22a is molded using an elastic member.

  In FIG. 11B, when a force is applied in the direction in which the sub valve V22a is pushed into the cell tube C2 as indicated by arrows Ya and Yb, the sub valve V22a is deformed from the broken line position to the solid line position in the drawing. The sub-valve V22a deformed to the position of the solid line is housed inside the cell tube C2.

  For this reason, as shown in FIG. 11C, when the sub valve V11 of the cell tube C1 and the sub valve V22a of the cell tube C2 are brought close to each other and connected, the sub valve V22a is housed inside the cell tube C2, as shown in FIG. 11D. Is done. In the state of FIG. 11D, the cell tube C1 and the cell tube C2 are connected in close contact. At this time, as shown in FIG. 11E, the sub valve V11 is not deformed and the sub valve V22a is deformed.

  By making all the sub-valves of the cell tubes C1 to C8 connected in an annular shape to be housed inside the cell tubes C1 to C8 as described above, the shape of the tube body after air filling is made uniform. Can do. Further, the sub-valve accommodated inside the cell tube is wrapped with the cell tube, so that the force applied to the sub-valve during traveling can be buffered, and damage to the sub-valve can be prevented. The surface fastener described with reference to FIGS. 8 to 10 may be provided around the portion where the sub-valve V11 and the sub-valve V22a are attached to connect the cell tubes more strongly.

  11D and 11E, when the cell tube C1 and the cell tube C2 are separated from each other, the sub valve V22a is deformed from the solid line position of FIG. 11B to the broken line position and returns to the state of FIG. 11A.

  A claw portion may be provided on one of the two sub-valves to be connected, and a recess may be provided on the other, and the claw portion and the recess may be engaged in a connected state. FIG. 12A is a perspective view illustrating an example of a sub-valve having a claw portion.

FIG. 12D is a cross-sectional view showing a state where the sub-valve having the claw portion and the sub-valve having the concave portion are connected. 12C and 12D are cross-sectional views of the sub-valve V11b and the sub-valve V22b taken along a plane including the central axis along the connecting direction of the sub-valves.

  As shown in FIG. 12A, claw portions T1 to T9 are provided around the sub valve V22b. The distances from the central axis of the hole Vh of the sub-valve V22b to the claw portions T1 to T9 are the same. As described above with reference to FIG. 11B, the sub-valve V22b is housed inside the cell tube when a force is applied in the direction of pushing into the cell tube. At this time, the claw portions T1 to T9 fall down so as to approach the central axis of the hole Vh.

  Moreover, as shown to FIG. 12B, the recessed part U is provided in the outer periphery of the root part of subvalve V11b. The tip portions of the claw portions T1 to T9 have a shape that can be engaged with the recess U.

  Therefore, as shown in FIG. 12C, when the sub valve V11b of the cell tube C1 and the sub valve V22b of the cell tube C2 are brought close to each other and connected, the sub valve V11b is not deformed and the sub valve V22b is While being deformed and housed inside the cell tube C2, the claws T1 to T9 fall down so as to approach the central axis of the hole Vh. The state of FIG. 12D is a state where the claw portion T of the sub valve V22b and the concave portion U of the sub valve V11b are engaged.

  By making all the sub-valves of the cell tubes C1 to C8 connected in an annular shape to be housed inside the cell tubes C1 to C8 as described above, the shape of the tube body after air filling is made uniform. Can do. Further, the sub-valve accommodated inside the cell tube is wrapped with the cell tube, so that the force applied to the sub-valve during traveling can be buffered. Thereby, damage of a subvalve can be prevented and durability of a subvalve can be secured. Furthermore, since the nail | claw part T and the recessed part U will be in the engaged state, cell tubes can be connected more strongly and it can suppress that the connection state of cell tubes is cancelled | released.

  In addition, if the cell tube C1 and the cell tube C2 are pulled apart in the state of FIG. 12D, the subvalve V22b will return to the original state shown to FIG. 12A and FIG. 12C.

  Furthermore, when the air pressure inside the cell tube is lowered, a structure in which the connection state between the sub-valves is released may be adopted. FIG. 13 is a diagram showing the structure of the sub-valve that is released from the connection state when the air pressure is lowered, and is a diagram showing a cross-section taken along a plane including the central axis along the connection direction with the other sub-valve. .

  FIG. 14A is a diagram illustrating cell tubes C3 to C5 among the cell tubes C1 to C8 connected in an annular shape. The sub-valves are connected so that air can pass in the direction of the arrow shown in FIG. 14A. For example, the sub valve V41b of the cell tube C4 and the sub valve V52c of the cell tube C5 are connected. In a state where the sub valve V41b and the sub valve V52c are connected, the sub valve V41b is housed inside the cell tube C5 without being deformed.

  At this time, the sub valve V52c and the sub valve V41b are connected as shown in FIG. 14B. That is, the sub valve V52c is deformed and accommodated inside the cell tube C5, and the claw portion T of the sub valve V52c and the recess U of the sub valve V41b are engaged. And the front-end | tip part of the subvalve V41b is in contact with the valve B, The valve B is in the open state (state through which air passes). That is, the valve B opens and allows air to pass through in a state where the sub valve V52c and the sub valve V41b are connected.

  When the cell tube C4 is damaged as shown in FIG. 14C in the state where the cell tubes C3 to C5 are connected in this manner, as shown in FIG. 14C, the internal pressure of the cell tube C5 connected to the cell tube C4 rapidly increases. descend. Then, in the cell tubes C3 to C5, the pressure between the cell tubes becomes unbalanced, the vicinity of the sub valve V52c of the cell tube C5 is locally deformed, the claw portion T opens in the directions of arrows Yd and Ye, and the claw portion T And the recess U are released. By releasing the engaged state, the sub valve V41b of the damaged cell tube is easily detached from the sub valve V52c.

  The cell tubes C3 to C5 are repeatedly deformed along with the tire ground rotation, and the connected sub valve V52c and sub valve V41b are disconnected. At this time, as shown in FIG. 14D, air flows in the cell tube C5 as indicated by arrows Y1 to Y5. Due to this air flow, the valve B rotates from the position of the broken line in the figure to the position of the solid line in the direction of the arrow Yc around the axis J.

  When the valve B further rotates about the axis J in the direction of the arrow Yc, the rotation of the valve B stops at the position of the solid line shown in FIG. 14E. At this time, the valve B is in a closed state (air does not pass through), airtightness can be secured, and a decrease in the internal pressure of the cell tube C5 is suppressed. That is, since the valve B is closed in a state where the connection state between the sub valve V52c and the sub valve V41b is released, the valve B acts as a check valve that prevents the air pressure in the cell tube C5 from being released.

  The valve B may be formed of a member having higher bending rigidity than the sub valve V52c. By doing this, when the internal pressure of the cell tube C4 decreases, the tip of the sub valve V41b is pushed by the rotation of the valve B, and the assist for releasing the engagement state between the claw T and the recess U is provided. While closing the valve B, the action of pushing the sub valve V41b to the outside of the cell tube C5 can be strengthened.

  Even if one cell tube is punctured by configuring the tube body 3 with a plurality of cell tubes C1 to C8 whose air chambers are independent from each other and making each cell tube C1 to C8 detachable independently. Since the load can be held by another cell tube, it is possible to continue running after puncture. In addition, when puncture occurs, the damaged cell tube repeats grounding and non-grounding due to rotation by running, and local vibration increases, so it becomes easier for the driver to detect puncture, and It can slow down the propagation of damage throughout the tire. Furthermore, when puncture occurs, only the punctured cell tube needs to be replaced.

  FIG. 15 is a perspective view of the tread ring 5. The tread ring 5 is a solid elastic body. The tread ring 5 extends over the entire circumference in the tire circumferential direction and has a ring shape as a whole. The tread ring 5 is made of a known material used as a tread rubber material in a normal pneumatic tire. The outer peripheral surface 51 of the tread ring 5 contacts the road surface when the tire rolls, and corresponds to the tread surface of the pneumatic tire. A tread pattern having a predetermined pattern is formed on the outer peripheral surface 51 of the tread ring 5 in order to improve traveling performance on a wet road surface. A tread pattern having a predetermined pattern is also formed on the inner peripheral surface 53 of the tread ring 5, and the outer peripheral surface 51 and the inner peripheral surface 53 of the tread ring 5 communicate with each other through a through hole 55 extending in the tire radial direction. It may be. As a result, water on the road surface can be more efficiently discharged from the ground contact surface.

  In the assembled tire 100, there are no portions corresponding to the bead portion, the sidewall portion, and the shoulder portion of the pneumatic tire, and no carcass or the like is disposed in the tire. For this reason, it is not necessary to individually manufacture each part such as a carcass, a belt, a tread, and a bead and then assemble it into a single tire with a molding machine, so that the manufacturing is easy. Further, the amount of rubber used for one tire can be reduced.

  In conventional pneumatic tires including run-flat tires, if the tire punctures, the entire tire must be replaced. On the other hand, in the assembled tire 100, even if the tire is punctured, it is only necessary to replace the tube body 3 or the punctured cell tube, so that the replacement cost of the tire due to puncture is reduced. Further, when the tread ring 5 is worn, only the tread ring 5 can be replaced. Furthermore, by properly using a plurality of tread rings having various tread patterns and materials, desired performance according to the road surface condition can be easily obtained.

  Moreover, in the assembled tire 100, the impact received from a road surface at the time of tire rolling can be buffered with the gas in the tube body 3 like a pneumatic tire. For this reason, the assembled tire 100 can have riding comfort performance equivalent to that of a pneumatic tire.

  Further, in the assembled tire 100, the tube body 3 is easily deformed instead of the ground contact portion of the tread ring 5 when the tire rolls. That is, when the tire rolls, the entire tire is deformed eccentrically, and the rotation center of the tire is deviated, so that the deformation of the contact portion of the tread portion is reduced. For this reason, energy loss becomes small and the rolling resistance of the tire becomes small. As a result, the assembled tire 100 can have excellent fuel efficiency.

  The assembled tire 100 further includes a tube reinforcing member 7 that at least partially surrounds the tube body 3. FIG. 16 shows a partial perspective view of the tube reinforcing member 7. In FIG. 16, a part of the tube reinforcing member 7 is cut and omitted for easy understanding. The tube reinforcing member 7 extends over the entire circumference in the tire circumferential direction and has a hollow ring shape as a whole. The tube reinforcing member 7 is placed on the tube body 3, and the tube body 3 is accommodated in the hollow portion of the tube reinforcing member 7. In the present embodiment, the tube reinforcing member 7 surrounds the outer side in the tire radial direction and the outer side in the tire width direction of the tube body 3. Note that the tube reinforcing member 7 has a sheet shape, and after being covered with the tube body 3, both ends may be bonded so as to have a ring shape as a whole.

  The tube reinforcing member 7 is made of a cord. The cord is, for example, a woven fabric, a biaxial woven fabric in which warp and weft intersect at 90 °, and two warps intersect at 60 ° with respect to one weft. The three-axis woven fabric or the four-axis woven fabric in which two yarns are crossed at an angle of 45 ° to the yarn crossing the length and width of the biaxial fabric. The material of the cord is, for example, polyester, nylon, rayon, aramid, polyketone, polyethylene naphthalate, or a mixture thereof. The cord may be either a single wire or a stranded wire. The cord may be covered with rubber or resin, or may be surface-treated in advance by dipping treatment or the like.

  FIG. 17 is a partial plan view of the tube reinforcing member 7 and shows an example of the configuration of the tube reinforcing member 7. As a weaving method of the tube reinforcing member 7, plain weave, twill weave, triaxial weave, or the like can be used. In the example of FIG. 17, the cord of the tube reinforcing member 7 is a biaxial fabric in which the warp yarn 71 and the weft yarn 73 intersect at 90 °.

  After the tube body 3 is assembled to the rim 11, when the gas is filled therein, the tube body 3 expands in the tire radial direction and the tire width direction. At this time, expansion toward the inside in the tire radial direction is suppressed by the rim 11, and expansion toward the outside in the tire radial direction is suppressed by the tread ring 5. However, since there is no member on the outer side in the tire width direction of the tube body 3, the expansion of the tube body 3 to the outer side in the tire width direction cannot be suppressed. For this reason, the tire width direction position of the tube body 3 with respect to the rim 11 or the tread ring 5 may be shifted at the time of tire rolling, which means that the ride performance is lowered, the rolling resistance is increased, and the fuel efficiency is lowered. Bring.

  In the present embodiment, the tube body 3 is covered with the tube reinforcing member 7, and the tube reinforcing member 7 surrounds the outer side in the tire radial direction and the outer side in the tire width direction of the tube body 3. And expansion to the tire width direction outside can be controlled. For this reason, the assembly tire 100 provided with the tube reinforcement member 7 can have more excellent riding comfort performance and fuel consumption performance.

  Moreover, since the tube reinforcement member 7 covers the outer surface of the tube body 3, it can reduce that the tube body 3 is damaged by a protrusion. Therefore, the tube reinforcing member 7 can also improve the puncture resistance of the tire.

  The assembled tire 100 is used by being assembled to the rim 11. The rim 11 is made of a material such as aluminum. The rim 11 may be a normal rim used with a pneumatic tire.

  The tube reinforcing member 7 is preferably fixed to the rim 11. As a result, the displacement of the tube reinforcing member 7 during rolling of the tire can be reduced, so that the tube reinforcing member 7 can more effectively suppress the expansion of the tube body 3. Hereinafter, five exemplary modes for fixing the tube reinforcing member 7 to the rim 11 will be described.

  In the first aspect, the assembled tire 100 further includes two annular fixing rings 13. FIG. 18 shows a front view of the fixing ring 13. The fixing ring 13 is a solid elastic body. The fixing ring 13 extends over the entire circumference in the tire circumferential direction and has a ring shape as a whole. The fixing ring 13 is made of, for example, synthetic rubber such as butyl rubber, natural rubber, metal such as steel and aluminum alloy, thermosetting resin, thermoplastic resin, or carbon fiber reinforced plastic (CFRP) and glass fiber reinforced plastic (GFRP). ) And fiber reinforced plastic.

The tire meridional cross-sectional shape of the fixing ring 13 is not limited to the shape shown in FIG. 19 as long as the tube reinforcing member 7a can be pressed against the rim 11a. By using the two fixing rings 13, the tube reinforcing member 7a can be fixed to the rim 11a by using a normal rim 11a used together with a pneumatic tire. The two fixing rings 13 may be integrated with the tube reinforcing member 7a or may be separate.

  As shown in FIG. 19, the tube reinforcing member 7a is disposed at least from the position of the end of the tread ring 5a in the tire width direction to the position of the end of the rim 11a in a state of surrounding the tube body 3a.

  Here, the tube-type tire is manufactured by assembling a tube body constituted by a plurality of cell tubes, a tread ring, and a tube reinforcing member, which are provided as separate components. For example, in a tire store, each part may be arranged and assembled with respect to a rim worn by a store clerk when selling tires. Further, the user may assemble a tube-type tire immediately before using the tire. The tube type tire can be an assembly type by adopting the above-described configuration, and the weight of the tire, the number of parts can be reduced, and the manufacturing process can be simplified. Moreover, since it is an assembly type, it is easy to disassemble and replace parts after assembly. That is, the tube, the tread ring, and the tube reinforcing member are assembled as separate parts and can be separated. Hereinafter, a method for manufacturing an assembled tire will be described.

  The tube, the tread ring, and the fixing ring are manufactured through a material mixing step, a material processing step, a vulcanization step, an inspection step after vulcanization, and the like. The rim is manufactured by casting, forging, injection molding, cutting, or the like.

  FIG. 31 is a diagram illustrating an example of a method for assembling a tube-type tire / rim assembly including the assembled tire 100. As shown in FIG. 31, in step S1, each part is assembled as follows. First, one end of the tube reinforcing member 7 is attached to the inner side of the rim 11 (side closer to the vehicle body) by the fixing ring 13. In step S2, the other end of the tube reinforcing member 7 is brought closer to the outer side of the rim 11 (the side far from the vehicle body). The rim 11 has a hole 11h corresponding to the air valve V1 of the cell tube C1.

  Next, in step S3, the cell tubes C1 to C8 are connected by the sub valve or, if a connecting portion such as a hook-and-loop fastener is provided, and the tube reinforcing member 7 on the outer side of the rim 11 The connected cell tubes C <b> 1 to C <b> 8 are introduced into the tube reinforcing member 7 from the gap with the rim 11. The cell tubes C1 to C8 that are not filled with gas may be introduced into the tube reinforcing member 7 and the cell tubes C1 to C8 may be connected inside the tube reinforcing member 7. The air valve V1 of the cell tube C1 is inserted into the hole 11h provided in the rim 11.

  Next, in step S <b> 4, the other end of the tube reinforcing member 7 is attached to the outer side of the rim 11 by the fixing ring 13. Thereafter, gas is filled into the cell tubes C1 to C8 from the air valve V1 of the cell tube C1. In step S <b> 5, the tread ring 5 is disposed outside the tube reinforcing member 7 in the tire radial direction. At this time, the tread ring 5 may be fixed to the tube reinforcing member 7 by being bonded to the tube reinforcing member 7. In step S <b> 6, the cell tubes C <b> 1 to C <b> 8 are in close contact with the outer peripheral surface of the rim 11 by further filling the cell tubes C <b> 1 to C <b> 8 from the air valve V <b> 1 of the cell tube C <b> 1.

  In addition, although the above demonstrated the example which fills the inside of a cell tube in two steps, you may fill with gas in a different timing (for example, before a cell tube is assembled | attached to a rim).

  The tread ring 5 may be bonded to the surface of the tube reinforcing member 7 with an adhesive. By bonding the tread ring 5 and the tube reinforcing member 7 with an adhesive, it is possible to ensure the durability of the connection state at the interface between the tread ring 5 and the tube reinforcing member 7. In order to strengthen the adhesive force, a surface treatment may be applied to at least the adhesive surface of the tube reinforcing member 7.

  As the adhesive used for bonding the tread ring 5 and the tube reinforcing member 7, for example, a two-liquid mixed type adhesive, more preferably a two-liquid mixed room temperature curing type adhesive can be used. A stimulus response type adhesive that causes a reversible reaction such as hardening or softening by a stimulus such as heat or electricity may be used.

The tread ring 5c including the reinforcing layer 50 has higher rigidity than the case where the reinforcing layer 50 is not included. The reinforcing layer 50 is formed using a material having higher bending rigidity than the outermost rubber of the tread ring 5c. For example, a rubber layer reinforced with an organic fiber cord such as steel, polyester, nylon, rayon, aramid, polyketone, polyethylene naphthalate, or a mixture thereof may be used as the reinforcing layer 50. The cord may be a single wire or a stranded wire. Moreover, you may comprise the reinforcement layer 50 with the material containing a thermosetting or thermoplastic resin. By using the tread ring 5c including the reinforcing layer 50, more stable running can be maintained.

In the example shown in FIG. 33, since the tube body 314 is divided into cell tubes 330, 332, and 334 divided in the width direction, even if one cell tube is punctured, the cell in which the entire area in the circumferential direction is filled with air. Any two of the tubes 330, 332, and 334 may remain. Thereby, more stable travel can be maintained.

  33 may have a structure in which a plurality of cell tubes are connected in the circumferential direction. That is, it may have a structure in which cell tubes divided in the tire width direction and the tire circumferential direction are connected. In that case, each cell tube should just be connected to the annular | circular shape by the sub valve by a non-return valve.

  33 may have a structure in which a plurality of cell tubes are connected in the tire radial direction. The cell tubes C1 to C8 shown in FIG. 1 may have a structure in which a plurality of cell tubes are connected in the tire radial direction.
