Description

  The present invention relates to a wheel run-out adjusting device used for adjusting run-out of a wheel attached to a vehicle body such as a motorcycle (motorcycle), a motor tricycle, and a bicycle.

  If the wheel attached to the vehicle body has a large runout, the stability and operability during traveling deteriorates, and thus it is necessary to adjust the runout of the wheel. For example, conventionally, a spoke wheel (hereinafter abbreviated as a wheel) is removed from the vehicle body, and both ends of an axle supported by the wheel are supported by a pair of bearing members attached to the shake table. The point where the gauge attached to is brought into contact with the wheel rim side surface is specified. The spoke nipple on the opposite side of the contact with the gauge was tightened to adjust the wheel runout.

  However, not only is there a backlash between the axle that is supported by the wheel and the bearing member that supports the axle of the shaker, but the degree of runout of the wheel is also checked to visually check the runout at the location where the gauge contacts. Is difficult to accurately grasp, and it is difficult to adjust the wheel runout with high accuracy. In addition, after removing the wheel from the vehicle body and adjusting the runout, it is necessary to take time and effort to adjust the runout of the wheel because the runout adjusted wheel is attached to the vehicle body again. It was impossible to adjust.

In addition, as an apparatus for measuring the above-described shake, for example, an apparatus is proposed in which an arm is rotated around an axis about an axis element, and a deviation of a stator fin is measured with a dial gauge attached to the arm. (See Patent Document 1).
However, since the shaft element that supports the arm and the shaft portion that supports the stator fin are separated, it is difficult to prevent the center of the shaft element and the shaft portion from being displaced. Since errors are likely to occur, it is difficult to correct the deviation of the stator fins.

  An object of the present invention is to provide a wheel shake adjusting device that can adjust the wheel shake with high accuracy without removing the wheel from the vehicle body.

  The present invention relates to a wheel runout adjustment device for adjusting runout of a wheel attached to a vehicle body, the support member fixed substantially concentrically with the axle supported by the wheel, and the wheel centered on the support member. , A support arm that is rotated in the circumferential direction, and a shake measuring unit that measures the shake of the wheel supported by the support arm.

According to the present invention, the runout of the wheel can be adjusted with high accuracy without removing the wheel from the vehicle body.
In detail, when adjusting the runout of the wheel, for example, after removing the wheel from the vehicle body, bearing both ends of the axle of the wheel with the bearing member of the shaker, and then measuring the runout of the wheel with the gauge attached to the shaker And adjusted. However, not only is there a backlash between the axle that is supported by the wheel and the bearing member that supports the axle of the shaker, but the degree of runout of the wheel is also checked to visually check the runout at the location where the gauge contacts. Is difficult to accurately grasp, and it is difficult to adjust the wheel runout with high accuracy.

  On the other hand, the wheel runout adjusting device of the present invention fixes the support member so as to be substantially concentric with the axle supported by the wheel while the wheel is attached to the vehicle body. After that, the support arm to which the shake measuring means is attached is rotated about the support member around the axis, and the part where the shake of the wheel seems to be large by the shake measuring means (specifically, the rim side part) And the run-out of the part where the run-out of the wheel seems to be small is measured.

  When measuring the wheel runout as described above, the support member is fixed substantially concentrically with the axle so that the relative position between the support member and the axle is not displaced during the runout measurement of the wheel. Since an error is hardly generated in the measured value measured by the above, the degree of wheel shake can be accurately measured by the shake measuring means.

Based on the measurement results described above, the wheel swing width is adjusted to be a predetermined value or less, so that the wheel swing can be finely adjusted with high accuracy without removing the wheel from the vehicle body.
As a result, vibration and vibration are less likely to occur during wheel rotation, the gyro effect due to wheel rotation is further enhanced, and stability during vehicle running such as a driving posture during high-speed driving and an aerial posture during jumping can be improved. it can.
In addition, since the above-described shake adjustment (or balance adjustment) is performed with the wheel attached to the vehicle body, the labor and work of attaching and detaching the wheel can be saved, and the work time required for shake adjustment can be greatly shortened. .

Here, the said vehicle body can be comprised with the vehicle body in a motorcycle (motorcycle), a motor tricycle, a bicycle etc., for example. The wheel can be constituted by, for example, a spokeless wheel or a spoke wheel to which a tire is attached. Further, the axle can be constituted by an axle shaft, for example.
Furthermore, the support member can be constituted by, for example, a positioning bolt in which a thread portion is threaded, or a shaft-shaped member, a rod-shaped member, a columnar member, a cylindrical member, or the like. Further, the shake measuring means can be constituted by a measuring instrument such as a diamond gauge, for example.

  In addition, as a specific example of adjusting the runout of the wheel, for example, when the axle is supported orthogonally to the radial center of the wheel such as a spokeless wheel or a spoke wheel, it is attached to the swing arm of the vehicle body. The adjusted adjuster bolt and nut are rotated, and the chain adjuster that supports the wheel axle is moved and adjusted in the longitudinal direction of the vehicle body. Also, when adjusting the spoke wheel runout, tighten the spoke nipple on the opposite side of the wheel runout.

  As an aspect of the present invention, a swing arm attached so as to be swingable up and down with respect to the vehicle body, a receiving groove formed in a swing side end portion of the swing arm in parallel with the front-rear direction of the vehicle body, and the receiver A bearing member for bearing the axle mounted slidably with respect to the groove; and a positioning member mounted on the bearing member in parallel with the longitudinal direction of the vehicle body, the bearing member having an end of the axle. A bearing hole in which the part is bearing, the positioning member is provided with an insertion hole in which insertion of the support member is allowed, and a portion of the positioning member facing the outer peripheral surface of the support member A positioning recess that regulates the support member concentrically with the insertion hole is provided, and a portion of the support member facing the inner peripheral surface of the positioning recess is allowed to be fitted into the positioning recess. A positioning convex portion is provided to be fitted in a direction in which the support member is inserted into the insertion hole, and the bearing member and the positioning member are restricted to a mounting position where the bearing hole and the insertion hole are concentric. It is possible to provide mounting position restricting means.

According to the present invention, it is possible to adjust the shake of the wheel with respect to the vehicle body with high accuracy.
More specifically, for example, in a motorcycle, when adjusting the runout of a wheel attached to a swing arm of a vehicle body, a chain adjuster that rotates an adjuster bolt and nut attached to the swing arm to support the wheel axle. Is moved in the front-rear direction of the vehicle body in accordance with the scales or the like carved on the swing arm to adjust the shake of the wheel with respect to the vehicle body. However, it is difficult to accurately determine the degree of wheel run-out because it visually confirms the degree of run-out of the wheel against the vehicle body, and it is also necessary to adjust the wheel run-out with high accuracy because it is adjusted by the longitudinal movement of the chain adjuster. Is difficult.

  In contrast, the wheel runout adjusting device of the present invention mounts the positioning member in a state parallel to the front-rear direction of the vehicle body with respect to the bearing member attached to the receiving groove of the swing arm while the wheel is attached to the vehicle body. The mounting position where the positioning convex portion of the support member is fitted into the positioning concave portion of the positioning member, and the bearing hole of the bearing member and the insertion hole of the positioning member are concentric by the mounting position restricting means. To regulate.

  Subsequently, when the support arm to which the shake measuring means is attached is rotated around the axis around the support member, there is no backlash between the positioning member and the support member. Sometimes, errors are less likely to occur, and the degree of shake of the wheel relative to the vehicle body can be accurately measured by the shake measurement means.

  Based on the measurement results described above, the width of the wheel relative to the vehicle body is adjusted so that it is less than or equal to the predetermined value, so that the wheel can be finely adjusted with high accuracy without removing the wheel from the vehicle swing arm. And the adjustment accuracy can be improved.

As a result, the gyro effect due to the rotation of the wheel becomes higher, the vehicle body is less likely to tilt to the left and right, and the restoring force in the direction of standing the vehicle body becomes greater. The stability inside is improved.
Here, the above-mentioned bearing member can be constituted by, for example, a positioning adjuster, a chain adjuster, or the like.

  In the above-described configuration, the swing adjustment of the wheel with respect to the vehicle body is performed with reference to the receiving groove of the swing arm or the bearing member attached to the receiving groove. For example, with respect to the shaft end surface orthogonal to the axis of the axle. The deflection may be adjusted based on a vertically arranged member.

  Further, as an aspect of the present invention, the mounting position restricting means includes a positioning hole portion opened in a direction facing the positioning member with respect to a mounting surface on which the positioning member of the bearing member is mounted, and the positioning A positioning protrusion that protrudes in a direction facing the bearing member with respect to a mounting surface of the member to be mounted on the bearing member, and the positioning protrusion and the positioning hole portion are arranged in the longitudinal direction of the vehicle body.

More specifically, when the positioning member is mounted on the bearing member, if the positioning protrusion of the positioning member is inserted in a direction perpendicular to the longitudinal direction of the vehicle body with respect to the positioning hole portion of the bearing member, the positioning member is It is fixed to the member in a state parallel to the longitudinal direction of the vehicle body.

  Thus, even if foreign matter such as dust enters between the opposing surfaces of the positioning member and the bearing member, the parallelism of each member is not displaced, and the positioning member is moved in the longitudinal direction of the vehicle body with respect to the bearing member. And can be kept attached in parallel.

  Further, there is no backlash between the support member, the positioning member, and the bearing member, and an error is less likely to occur when the wheel shake is measured by the shake measurement means. Further, even if an error occurs, the value thereof is small, so that the degree of deflection of the wheel with respect to the vehicle body can be measured more accurately by the deflection measuring means.

Based on the measurement results described above, the adjustment is made so that the fluctuation width of the wheel relative to the vehicle body is equal to or less than a predetermined value. Therefore, the vibration of the wheel relative to the vehicle body can be finely adjusted with higher accuracy without removing the wheel from the vehicle body. .
Here, the bearing member and the positioning member can be configured in a desired shape such as a round shape, an elliptical shape, a rectangular shape, an octagonal shape, and the like. Moreover, the positioning protrusion and the positioning hole can be configured to have a desired cross-sectional shape such as a round shape, a quadrangular shape, a triangular shape, or a hexagonal shape.

Specifically, if the wheel is attached to the vehicle body, the shaft of the support member is inserted into the hole of the axle, and the positioning shaft of the support member is fitted into the positioning hole of the axle. Fixed to be concentric.

Further, there is no backlash between the support member and the axle, and errors are less likely to occur when measuring the wheel runout by the runout measuring means. Further, even if an error occurs, the value thereof is small, so that the degree of deflection of the wheel relative to the axle can be measured more accurately by the deflection measuring means.
Based on the measurement result described above, the wheel is adjusted so that the swing width of the wheel relative to the axle is equal to or less than a predetermined value. Therefore, the swing of the wheel relative to the axle can be finely adjusted with high accuracy without removing the wheel from the vehicle body.

  Further, as an aspect of the present invention, the inner peripheral surface of the hole portion formed on one end side of the axle and the outer peripheral surface of the shaft portion formed on one end side of the support member are allowed to be screwed together. The female screw hole and the male screw portion can be threaded.

In addition, on the mounting surface 80a of the positioning adjuster 80 facing the positioning block 70, an elliptical concave receiving portion 82 is formed with the flange portion 2c of the axle shaft 2A being non-rotatably fitted around the bearing hole 81. doing.

  The concave receiving portion 82 is formed in a size and shape corresponding to the flange portion 2c, and is formed at a depth at which the flange portion 2c is held at a height that is substantially the same as the mounting surface 80a. In addition, you may form in the depth by which the flange part 2c is hold | maintained inside the mounting surface 80a.

Further, the inner diameter of the positioning hole 83 is slightly larger than the outer diameter of the positioning pin 73.
Further, the inner periphery of the positioning hole 83 is fitted so as to be rotatable with respect to the outer periphery of the positioning pin 73, and is processed into an inner diameter and a surface roughness that allow the entire peripheral surface to come into surface contact without backlash.

The wheel shake adjusting device 10 described above can be used when adjusting the shake of the wheel 1A attached to the rear part (rear side) of the vehicle body as shown in FIGS.
6 is an explanatory diagram for mounting the positioning block 70 to the positioning adjuster 80, FIG. 7 is an explanatory diagram for fitting the positioning bolt 20 to the positioning block 70, and FIG. 8 is an explanatory diagram for fitting the positioning bolt 20 to the positioning block 70. FIG. 9 is an explanatory diagram of a procedure for attaching the positioning block 70 and the positioning bolt 20.

  FIG. 10 is an explanatory diagram of a procedure for attaching the dial gauge 60. Specifically, FIG. 10A is an explanatory diagram for fixing the support rod 50 to the support arm 30, and FIG. 10B is an illustration of attaching the dial gauge 60 to the support rod 50. It is explanatory drawing.

  11A and 11B are explanatory diagrams for explaining the vibration adjustment of the wheel 1A. Specifically, FIG. 11A is an explanatory diagram in which the wheel shake adjusting device 10 is fixed to the axle shaft 2A of the wheel 1A, and FIG. It is explanatory drawing rotated 90 degree | times.

  When adjusting the shake of the wheel 1A using the wheel shake adjusting device 10 described above, a positioning adjuster 80 is attached in advance to the concave receiving groove 3a of the swing arm 3 in place of a general chain adjuster, and the wheel 1 The left and right ends of the axle shaft 2A that is supported on the right side are supported by a positioning adjuster 80 attached to the right free end of the swing arm 3 and a chain adjuster (not shown) attached to the left free end (FIGS. 6 and 9). (See (a)).

  Next, the mounting surface 70a of the positioning block 70 is brought into surface contact with the mounting surface 80a of the positioning adjuster 80 while the positioning pins 73 of the positioning block 70 are inserted into the positioning holes 83 of the positioning adjuster 80, respectively. Then, the positioning block 70 is mounted on the positioning adjuster 80 (see FIGS. 6 and 9B).

  Since the receiving surface 3b of the concave receiving groove 3a of the swing arm 3 is parallel to the longitudinal direction A of the vehicle body, when the mounting surface 80b of the positioning adjuster 80 is mounted in surface contact with the receiving surface 3b of the concave receiving groove 3a, The mounting surface 80a of the positioning adjuster 80 is parallel to the longitudinal direction A of the vehicle body.

  Therefore, if the mounting surface 70a of the positioning block 70 is mounted in surface contact with the mounting surface 80a of the positioning adjuster 80, the positioning block 70 is mounted in a state parallel to the longitudinal direction A of the vehicle body with respect to the positioning adjuster 80. (See FIGS. 6 to 8).

Further, the insertion hole 71 of the positioning block 70 and the bearing hole 81 of the positioning adjuster 80 are communicated with each other in a concentric state. Thereafter, it is confirmed that the mounting surface 70a of the positioning block 70 and the mounting surface 80a of the positioning adjuster 80 are in contact with each other.
Before mounting the positioning block 70, the mounting surface 70a of the positioning block 70 and the mounting surface 80a of the positioning adjuster 80 are cleaned in advance.

  Next, the positioning bolt 20 of the wheel runout adjustment device 10 is inserted into the insertion hole 71 of the positioning block 70 and is also inserted into the through-hole 2a of the axle shaft 2A fitted in the concave receiving portion 82 of the positioning adjuster 80 to perform positioning. The male screw portion 23 of the bolt 20 is screwed into the female screw hole 2b of the axle shaft 2A (see FIG. 7).

  Further, the positioning bolt 20 is rotated by a rotating operation tool (not shown) and tightened, and the positioning convex portion 24 of the positioning bolt 20 is fitted to the positioning concave portion 72 of the positioning block 70 without rattling. The outer peripheral surface 24b of the convex portion 24 is brought into surface contact with the inner peripheral surface 72b of the positioning concave portion 72 so as to be rotatable.

  By tightening the positioning bolt 20 to a position where the distal flat surface 24a of the positioning convex portion 24 abuts against the inner flat surface 72a of the positioning concave portion 72, the positioning bolt 20 is orthogonal to the longitudinal direction A of the vehicle body. It can be firmly fixed to the state (see FIGS. 8 and 9C).

  Further, the positioning projection 20 of the positioning bolt 20 is fitted into the positioning recess 72 of the positioning block 70 so that the positioning bolt 20 is orthogonal to the longitudinal direction A of the vehicle body (or parallel to the lateral direction B of the vehicle body). Attached).

Further, by inserting the positioning pins 73 into the positioning holes 83, the mounting surface 70a of the positioning block 70 and the mounting surface 80a of the positioning adjuster 80 are supported in parallel.
For this reason, even if a foreign substance such as dust enters between the opposing surfaces of the mounting surface 70a and the mounting surface 80a, the parallelism of the mounting surfaces 70a and 80a is not displaced, and the positioning block 70 is moved to the positioning adjuster 80. On the other hand, it can be kept attached in parallel with the longitudinal direction A of the vehicle body.

  Next, after the fixing of the positioning bolt 20 to the positioning block 70 is completed, the bolt receiving portion 31 b of the support arm 30 is fitted to the arm support portion 26 of the positioning bolt 20, and the fastening screw 40 is used to fix the positioning bolt 20. The arm support portion 26 and the bolt receiving portion 31b of the support arm 30 are fixed so as to be rotatable (see FIGS. 7 and 8). The positioning bolt 20 and the support arm 30 may be assembled in advance.

Subsequently, the male screw portion 55 of the support rod 51 in the support rod 50 is screwed into the female screw hole 35 of the support arm 30 to fix the support rod 51 to the free end side of the support arm 30.
An extension rod 52 is attached to the support rod 51 via a holding member 53. A dial gauge 60 is attached to the extension rod 52 via a holding member 54 (see FIGS. 10A and 10B).

  By operating the holding members 53 and 54, the dial gauge 60 is adjusted to a position and an angle at which the probe 62 of the display unit 61 is pressed substantially perpendicular to the rim side surface portion of the wheel 1 </ b> A. The measuring element 62 is pressed against the rim side surface part where the vibration of the wheel 1A seems to be large, and the numerical value of the part is measured (see FIG. 11A).

  Subsequently, the support arm 30 is rotated about 90 degrees around the positioning bolt 20, and at the rotated position, the deflection of the side surface of the rim against which the probe 62 of the dial gauge 60 is pressed is measured (see FIG. 11 (b)). Note that the shake of a plurality of portions may be measured.

As described above, since the positioning bolt 20, the support arm 30, the positioning block 70, and the positioning adjuster 80 are integrally fixed, the dial gauge 60 remains attached to the swing arm 3 of the vehicle body. When the support arm 30 to which is attached is rotated about the axis around the positioning bolt 20 concentrically fixed to the axle shaft 2A, no rattling occurs.
For this reason, an error is unlikely to occur in the measurement value measured by the dial gauge 60, and even if an error occurs, the value is small, so that the degree of deflection of the wheel 1A relative to the vehicle body can be measured more accurately.

Based on the measurement result described above, the adjuster bolt 4 and the nut 5 attached to the left free end of the swing arm 3 are rotated, and the chain adjuster at the left free end is moved in the front-rear direction A to move the wheel 1A. The axle shaft 2A is adjusted to an attachment angle orthogonal to the longitudinal direction A of the vehicle body (or an attachment angle parallel to the lateral direction B of the vehicle body).
That is, the above adjustment is repeated several times to finely adjust the swing width of the wheel 1A with respect to the vehicle body to a predetermined value or less, so that the wheel 1A with respect to the vehicle body of the wheel 1A is not removed from the swing arm 3 of the vehicle body. The shake can be finely adjusted with higher accuracy.

As a result, the gyro effect due to the rotation of the wheel 1A becomes higher, the vehicle body is less likely to tilt to the left and right, and the restoring force in the direction of standing the vehicle body becomes larger. Stability during driving is improved.
In addition, since the above-described shake adjustment (or balance adjustment) is performed while the wheel 1A is attached to the vehicle body, labor and work for attaching / detaching the wheel 1A to / from the vehicle body can be saved, and work time required for shake adjustment can be greatly increased. Can be shortened.

  Since the wheel 1A (spokeless wheel) described above is bearing the axle shaft 2A perpendicular to the wheel 1A, the mounting angle of the axle shaft 2A is changed to the longitudinal direction A of the vehicle body by the longitudinal movement of the chain adjuster. By adjusting the orthogonal mounting angle (or the mounting angle parallel to the left-right direction B of the vehicle body), the shake adjustment (or balance adjustment) can be performed in an optimum state according to the vehicle body condition (see FIG. 18). .

For example, when the wheel 1A supported by the swing arm 3 is swinging in the left-right direction B (vehicle width direction) of the vehicle body as indicated by the phantom line in FIG. 18, the swing of the wheel 1A is adjusted as described above. Then, the shake of the wheel 1A can be adjusted to the state shown by the solid line in FIG. FIG. 18 is an explanatory diagram that simplifies the swing adjustment of the wheel 1A.
In addition, if the axle shaft 2B is bearing orthogonally with respect to the spoke wheel 1B described later, the vibration of the spoke wheel 1B relative to the vehicle body can be adjusted in the same manner as described above.

  Further, when the wheel runout adjusting device 10 is removed from the wheel 1A supported by the swing arm 3, when the runout adjustment of the wheel 1A is completed, the positioning bolt 20 is turned by a turning operation tool (not shown) to release the fixing. After that, the male screw portion 23 of the positioning bolt 20 is extracted from the female screw hole 2b of the axle shaft 2A and separated from the positioning block 70 and the positioning adjuster 80. Thereby, the wheel shake adjusting device 10 can be removed from the wheel 1A.

  Further, in the above-described shake adjustment work, the case has been described in which the positioning bolt 20, the support arm 30, the tightening screw 40, the support rod 50, and the dial gauge 60 are assembled in order to adjust the shake of the wheel 1A. These may be assembled in advance, and in the place where the shake adjustment of the wheel 1A is performed, the labor and work of assembling the above-mentioned parts can be saved, and the shake adjustment work can be executed immediately.

  In the above-described embodiment, the operation of adjusting the shake of the spokeless wheel 1A using the wheel shake adjusting device 10 has been described. However, as shown in FIGS. 12, 13, and 14, the wheel shake adjusting device 10 includes: It can also be used when adjusting the deflection of the spoke wheel 1B (hereinafter abbreviated as wheel 1B) attached to the rear part (rear side) of the vehicle body.

  In this case, the positioning bolt 20 is replaced with a positioning bolt 200 that is directly fixed to the female screw hole 2b of the axle shaft 2B without using the positioning block 70 described above. Further, the positioning adjuster 80 is replaced with a general chain adjuster 800 (hereinafter, abbreviated as an adjuster 800) to adjust the runout.

FIG. 12 is a side view in which a positioning bolt 200 fixed concentrically to the axle shaft 2B is attached to the support arm 30, and FIG. 13 is an explanatory view in which the positioning bolt 200 is fixed to the axle shaft 2B.
FIG. 14 is an explanatory view of the vibration adjustment of the wheel 1B with respect to the axle shaft 2B. Specifically, FIG. 14A is an explanatory view in which the wheel shake adjusting device 10 is fixed to the axle shaft 2B of the wheel 1B, and FIG. It is explanatory drawing which rotated the adjustment apparatus 10 90 degree | times.
In the positioning bolt 200 and adjuster 800, the same components as those of the positioning bolt 20 and positioning adjuster 80 described above are denoted by the same reference numerals, and detailed description thereof is omitted.

  The above-described positioning bolt 200 is formed on the outer peripheral surface of the base end side of the male screw portion 23 in place of the positioning convex portion 24 described above, with respect to the positioning hole portion 2d formed on the inner periphery on the right end side of the through hole 2a in the axle shaft 2B. A positioning shaft portion 240 is formed to be fitted without rattling.

  The outer diameter of the positioning shaft 240 is slightly smaller than the positioning hole 2d of the through hole 2a. Further, the outer periphery of the positioning shaft portion 240 is fitted to the inner periphery of the positioning hole portion 2d so as to be rotatable, and is processed to have an outer diameter and a surface roughness that allow the entire peripheral surface to be in surface contact without backlash.

  When adjusting the deflection of the wheel 1B relative to the axle shaft 2B using the wheel deflection adjusting device 10 described above, the through hole of the axle shaft 2B in which the male thread portion 23 of the positioning bolt 200 is fitted to the concave receiving portion 82 of the adjuster 800 is used. The male screw portion 23 of the positioning bolt 200 is screwed into the female screw hole 2b of the axle shaft 2B.

  Further, the positioning bolt 200 is turned by a turning operation tool (not shown) and tightened, and the positioning shaft portion 240 of the positioning bolt 20 is fitted to the positioning hole portion 2d of the axle shaft 2B without rattling.

  The positioning bolt 200 is tightened to a position where the distal end side peripheral portion of the nut portion 25 is in contact with the mounting surface 80a of the adjuster 800, and is in a state orthogonal to the longitudinal direction A of the vehicle body (or the lateral direction B of the vehicle body). Fix it. Accordingly, the positioning bolt 200 is fixed concentrically with respect to the axle shaft 2B (see FIGS. 13 and 14).

  Next, the support arm 30 supported by the positioning bolt 200 is rotated around the axis (in the direction of the arrow) with the positioning bolt 200 as a center, and the deflection of the wheel 1B is measured by the dial gauge 60 (FIG. 14). (See (a) and (b)).

  As described above, since the axle shaft 2B and the positioning bolt 200 are fixed concentrically, there is no backlash between the axle shaft 2B and the positioning bolt 200, and when the wheel 1B is shaken by the dial gauge 60, Is less prone to errors. Further, even if an error occurs, the value is small, so that the degree of deflection of the wheel 1B relative to the axle shaft 2B can be measured more accurately.

  Based on the measurement result described above, the nipple 1e of the spoke 1d opposite to the portion where the wheel 1B is largely shaken is tightened to adjust the tension of the spoke 1d. This adjustment is repeated several times so that the swing width of the wheel 1B is adjusted to a predetermined value or less.

  As a result, since it is possible to accurately adjust the deflection of the wheel 1B relative to the axle shaft 2B with high accuracy without removing the wheel 1B from the vehicle body, it is possible to achieve substantially the same operations and effects as in the above-described embodiment.

  Furthermore, after adjusting the shake of the wheel 1B relative to the axle shaft 2B as described above, if the shake adjustment of the wheel 1B relative to the vehicle body is performed, the shake adjustment of the wheel 1B can be accurately performed with higher accuracy and fine adjustment is performed. be able to.

  Furthermore, as shown in FIG. 15, the wheel shake adjusting device 10 described above can also be used when adjusting the shake of the wheel 1B attached to the front part (front side) of the vehicle body. FIG. 15 is an explanatory view of the deflection adjustment of the front wheel 1B relative to the axle shaft 2B.

  When adjusting the deflection of the wheel 1B relative to the axle shaft 2B using the wheel deflection adjusting device 10 described above, after the positioning bolt 20 is replaced with the positioning bolt 200, the male screw portion 23 of the positioning bolt 200 is replaced with the female screw of the axle shaft 2B. The positioning bolt 200 is fixed so as to be concentric with the axle shaft 2C by screwing into the hole 2b.

  Next, the support arm 30 supported by the positioning bolt 200 is rotated around the axis (in the direction of the arrow) around the positioning bolt 200, and the degree of deflection of the wheel 1 </ b> B is measured by the dial gauge 60.

  Based on the measurement result described above, the nipple 1e of the spoke 1d opposite to the portion where the wheel 1B is largely shaken is tightened to adjust the tension of the spoke 1d. This adjustment is repeated several times so that the swing width of the wheel 1B is adjusted to a predetermined value or less.

  As a result, since it is possible to accurately adjust the deflection of the wheel 1B relative to the axle shaft 2B with high accuracy without removing the wheel 1B from the vehicle body, it is possible to achieve substantially the same operations and effects as in the above-described embodiment.

Furthermore, as shown in FIGS. 16 and 17, the wheel runout adjusting device 10 described above is a spoke wheel 1C (hereinafter referred to as a wheel 1C) attached to the front part (front side) of a bicycle other than a motorcycle. It can also be used to adjust the shake of (abbreviated as).
FIG. 16 is an explanatory diagram for adjusting the deflection of the wheel 1C in the bicycle, and FIG. 17 is an explanatory diagram in which the positioning bolt 200 and the axle shaft 2C are connected and fixed.

Since the male thread 2e is threaded on the peripheral surface of the left and right ends of the axle shaft 2C supported by the wheel 1C described above, when the positioning bolt 200 is fixed to the right end of the axle shaft 2C, a cylindrical shape is used. Are connected so as to be concentric.
Further, a female screw hole 310 that is allowed to be screwed into the male screw portion 2e of the axle shaft 2C is threaded on the inner periphery of both ends of the connecting member 300.

When adjusting the deflection of the wheel 1C relative to the axle shaft 2C using the wheel deflection adjusting device 10 described above, the positioning bolt 20 is replaced with the positioning bolt 200, and then the male screw portion 2e of the axle shaft 2C is connected to one end side of the connecting member 300. The female screw hole 310 is screwed, the male screw portion 23 of the positioning bolt 200 is screwed into the female screw hole 310 on the other end of the connecting member 300, and the positioning bolt 200 is connected and fixed so as to be concentric with the axle shaft 2C. (See FIG. 17).
Next, after the support rod 51 of the support rod 50 is replaced with a long rod corresponding to the radius of the wheel 1C, the support arm 30 supported by the positioning bolt 200 is rotated around the axis around the positioning bolt 200 ( Rotation is performed in the direction of the arrow, and the degree of deflection of the wheel 1C is measured with the dial gauge 60 (see FIG. 16).

  As described above, since the axle shaft 2C and the positioning bolt 200 are concentrically connected and fixed by the connecting member 300, there is no backlash between the axle shaft 2C and the positioning bolt 200, and the dial gauge 60 causes the wheel to rotate. Errors are less likely to occur when measuring 1C runout. Further, even if an error occurs, the value is small, so that the degree of deflection of the wheel 1C relative to the axle shaft 2C can be measured more accurately.

  Based on the measurement result described above, the nipple 1e of the spoke 1d opposite to the portion where the wheel 1C is largely shaken is tightened to adjust the tension of the spoke 1d. This adjustment is repeated several times so that the swing width of the wheel 1C is adjusted to a predetermined value or less.

As a result, since it is possible to accurately adjust the deflection of the wheel 1C relative to the axle shaft 2C with high accuracy without removing the wheel 1C from the vehicle body, it is possible to achieve substantially the same operations and effects as in the above embodiment.
The above-described wheel shake adjusting device 10 shown in FIGS. 16 and 17 can also be used when adjusting the shake of the wheel 1C attached to the rear body (rear side) of the bicycle.
