Description

  The present invention relates to an outer hood device for a high-speed railway vehicle, which has a belt-plate-shaped fixed outer hood fixed to a vehicle wife wall and one or two belt-plate-shaped movable outer hoods supported by a link mechanism. The present invention relates to a structure in which the outer hood is configured to be retractable to the inner side of the fixed outer hood through a link mechanism.

When the high-speed railway vehicle travels, a traveling wind flows along its side surface and roof. Due to this traveling wind, a violent eddy current is generated in the uneven portion of the vehicle surface, increasing wind noise and increasing traveling resistance. In particular, when there is a gap in the vehicle connecting portion, wind noise and running resistance become a problem. Recently, a Shinkansen (registered trademark) vehicle with a speed of 360 km / h is under development, but wind noise in high-speed railways deteriorates in proportion to the third power of the speed, so an outer hood device that closes the gap in the outer periphery of the vehicle connection part Noise is a problem.

  Conventionally, since noise has been evaluated based on noise measured at a point 25 m away from the traveling vehicle, it has not been easy to identify the site where the noise is generated from the traveling vehicle. The performance of the equipment has been improved, and it is now possible to measure in detail the location and sound pressure level of the noise. As a result of improvements in pantographs and downsizing of the drive motor to reduce noise, it is generated from the outer hood device of the vehicle connection part. Therefore, it has been found that the noise generated is greatly related to the environment along the railway line and the noise of the deck section in the vehicle.

  Conventionally, various outer hood devices have been proposed that cover the gaps in the outer periphery of the vehicle body at the vehicle connecting portion. In the low noise type outer hood of Patent Document 1, a plurality of belt-like planar members and a plurality of narrow-width recessed members are alternately arranged to integrally form the plurality of planar members by pantograph links. The plurality of dent members are urged inward by a holding spring and can be expanded and contracted in the front-rear direction through expansion and contraction of the pantograph type link and bending of the plurality of dent members.

  In the outer hood device for a high-speed vehicle disclosed in Patent Document 2, a pair of flexible outer hood members covering the gaps in the outer periphery of the vehicle connecting portion and a contact portion between the pair of outer hood members at appropriate locations. A pair of arm members that extend at right angles to the inside of the vehicle width, a Z-type link mechanism that is connected to the opposite end walls, and a base of the pair of arm members at the center of the main link member of the Z-type link mechanism A ball joint or the like for connecting the end portions is provided, and the ball joint is always positioned at an intermediate position of the connection portion, and the clearance between the outer peripheral portions is determined by opening and closing the pair of arm members and elastically deforming the pair of outer hood members. It is configured to be able to follow expansion and contraction.

  In the outer hood device for a high-speed railway vehicle of Patent Document 3, a flexible hood member having a U-shaped cross section is provided on each of the outer peripheral portions of the facing walls facing each other at the vehicle connecting portion, and the curved portions are brought into contact with each other. The base end portion of the outer wall portion of the hood member is fixed to the end wall, the base end portion of the inner wall portion of the hood member is movable, and the base end portion is pushed out by the air spring member and pulled in by another spring member. Thus, it is configured to be able to cope with expansion and contraction between the gaps between the wife walls.

  In the inter-connection rectification device for a railway vehicle of Patent Document 4, a belt-shaped rectification member is disposed over the entire circumference of the gap at the outer periphery of the vehicle body at the vehicle connection portion, and the rectification member is held at the center position of the gap. A support mechanism for moving the flow straightening member outward when the gap is reduced is provided.

  In the outer hood device for a railway vehicle of Patent Document 5, a pair of flexible belt-shaped outer hoods are respectively attached to the opposite end walls over the entire circumference of the gap at the outer periphery of the vehicle connecting portion. Each outer hood is supported in an unfolded state by Y-shaped links connected to air cylinders at appropriate locations, and a pair of metal frames provided at opposite ends of the pair of outer hoods are brought into contact with each other. A connection lock mechanism is provided that holds and holds a pair of metal frames in a separable manner.

In addition, in Shinkansen (registered trademark) vehicles, synthetic resin or rubber outer hood members are attached to the outer peripheries of a pair of opposite facing walls of the connected vehicles, and the tips of the outer hood members are attached to each other. The thing made the structure to contact | abut is also employ | adopted. In recent high-speed railway vehicles such as the Shinkansen (registered trademark) , an elastic outer hood that covers the surface of a urethane foam with a synthetic resin skin containing high-strength synthetic resin fibers is spread over the entire circumference of the gap at the outer periphery of the vehicle body. These elastic outer hoods are fixed to the end walls of both vehicles.

The restraint is released, the lock of the first link mechanism 14 is released, and the first movable outer hood 11 can move from the aligned position to the retracted position.

Next, the roof outer hood mechanism 7 will be described with reference to FIGS. 2, 9, and 10.
The roof outer hood mechanism 7 can hold the roof-side movable outer hood 71 and the roof-side movable outer hood 71 in an aligned position, and can move to a retracted position that partially overlaps the outer side of the roof-side fixed outer hood 70.

And a stopper mechanism 79 that restricts the forward and upward movement of the roof-side movable outer hood 71 in the contracted position, and the end surface of the roof-side movable outer hood 71 opposite to the roof-side fixed outer hood 70 is parallel to the end wall 1a. The movable side sliding contact plate 75 provided on the rear side, and the fixed side sliding contact plate 76 provided on the end wall 2a of the rear vehicle 2 facing the movable side sliding contact plate 75 are provided.

  The pair of left and right link mechanisms 73 connect a pair of link connecting portions 71a suspended from both ends in the vehicle width direction of the rear end portion of the roof-side movable outer hood 71 and the end wall 1a to fix the roof side fixed outer The roof-side movable outer hood 71 is configured to be a parallel link mechanism that moves the roof-side movable outer hood 71 in parallel between the aligned position and the retracted position. The link mechanism 73 includes a pair of upper and lower link members 80 and 81 and a tension spring 82 that urges the link member 81 to rotate. Each of the pair of link members 80 and 81 is disposed in an inclined manner with respect to the wife wall 1a so that the rear end is located above the front end and rotates in the vertical plane.

  The front end and the rear end of the link member 80 are pivotally supported by horizontal pins 80a and 80b, respectively. The front end pin 80a is supported by the lower part of the bearing member 83 fixed to the end wall 1a, and the rear end pin. 80 b is supported by the lower part of the bearing member 84 fixed to the link connection part 71 a of the roof-side movable outer hood 71. Similarly, the front end portion and the rear end portion of the link member 81 are pivotally supported by horizontal pins 81a and 81b, the front end pin 81a is supported on the upper portion of the bearing member 83, and the rear end pin 81b is the bearing member. 84 is supported at the top.

  The front end of the tension spring 82 is connected to a spring mounting portion 83 a that protrudes rearward from the lower portion of the bearing member 83, and the rear end portion is connected to a spring mounting portion 81 c that protrudes forward from the lower portion of the link member 81. The link member 81 is urged to rotate counterclockwise in FIG. 9 by the tension spring 82, and is movable on the roof side via the link member 81 by the tension spring 82 of the pair of link mechanisms 73. The outer hood 71 is elastically biased to the aligned position.

  The holding mechanism 74 includes a pair of left and right holding link mechanisms 85 corresponding to the pair of left and right link mechanisms 73. The holding link mechanism 85 includes a pair of link members 86 and 87 that are rotatably connected to each other and arranged to rotate in a vertical plane, and the front end portion of the link member 86 is a wife wall. The front end portion of the link member 87 is rotatably connected to the upper portion of the link member 80.

  When the roof-side movable outer hood 71 is in the aligned position, the pair of link members 86 and 87 are slightly bent into a downward convex shape, and the link members 86 and 87 are turned to a straight side. Is restricted, and the roof-side movable outer hood 71 is held in the aligned position. Therefore, even if the front vehicle 1 and the rear vehicle 2 are separated, the roof-side movable outer hood 71 is prevented from falling off. When the roof-side movable outer hood 71 moves from the aligned position to the retracted position, the pair of link members 86 and 87 are greatly bent downwardly, but the movement of the roof-side movable outer hood 71 to the retracted position is not possible. Not blocked.

  Next, the stopper mechanism 79 includes a pair of left and right upper stopper members 90 and a pair of left and right lower stopper members 95 respectively corresponding to the pair of link mechanisms 73. The stopper members 90 and 95 are each made of an elastic member (for example, rubber), and bolts 92 are attached to mounting members 91 and 96 fixed to the end wall 1a so that the link member 81 of the link mechanism 73 can come into contact with the rear side. , 97, and the rear end surfaces thereof are formed in a downwardly inclined shape. When the roof-side movable outer hood 71 moves to the retracted position and its front end reaches a position substantially above the end wall 1a of the front vehicle 1, the link member 81 abuts against the stopper members 90 and 95, and beyond Is restricted from moving forward and upward.

  The forward movement allowable amount of the roof-side movable outer hood 71 (movable-side sliding contact plate 75) is about 1 / of the forward movement allowable amount of the second movable outer hood 12 (movable-side sliding contact plate 17). However, there is no problem because the amount of reduction of the roof side gap 4 with respect to the side gap 3 is small. However, it is possible to increase the allowable amount of forward movement of the roof-side movable outer hood 71 by changing the positions and shapes of the stopper members 90 and 95.

The operation and effect of the outer hood device 5 described above will be described.
As shown in FIG. 11, when the knitted vehicle travels straight, the first movable outer hood 11 is held in the aligned position by the first link mechanism 14, and the second movable outer hood 12 is aligned by the second link mechanism 16. The outer surface of the fixed outer hood 10 and the first and second movable outer hoods 11 and 12 become a common surface, and the movable sliding plate 17 contacts the fixed sliding plate 18. Further, the roof-side movable outer hood 71 is held in the aligned position by the third link mechanism 72, and the outer surfaces of the roof-side fixed outer hood 70 and the roof-side movable outer hood 71 become a common surface, and the movable-side sliding contact plate 75 abuts against the fixed sliding contact plate 76.

  As shown in FIGS. 12 and 13, the first movable outer hood 11 is pushed forward by the rear vehicle 2 when the knitted vehicle is turning or when the side gap 3 is reduced at the point switching point. However, as shown in FIG. 12, when the turning radius is not so large, first, since the first link mechanism 14 is locked by the restricting mechanism 19, the second link mechanism 16 causes the second movable outer canopy to be locked. 12 is moved inward in the vehicle width direction and parallel to the front from the aligned position toward the retracted position.

As shown in FIG. 13, when the turning radius is large, the second movable outer hood 12 is moved to the retracted position, and the second movable outer hood 12 entirely overlaps the inner side of the first movable outer hood 11. Then, the lock by the restriction mechanism 19 of the first link mechanism 14 is released. Next, the first movable outer hood 11 is moved from the aligned position toward the retracted position by the first link mechanism 14, and this first movable The second movable outer hood 12 is also moved integrally with the movement of the outer hood 11. When the side gap 3 is reduced, the roof side gap 4 is reduced. At that time, the roof-side movable outer hood 71 is pushed forward by the rear vehicle 2, depending on the degree of reduction of the side gap 3. To move toward the retracted position.

The outer hood device 5 described above has the following effects.
The strip-shaped fixed outer hood 10 of the side outer hood mechanism 6, the first and second movable outer hoods 11, 12, and the strip-shaped roof-side fixed outer hood 70 of the roof-side outer hood mechanism 7 and the roof-side movable. The outer hood 71 can be made very compact with a metal or FRP strip, which is advantageous in terms of installation space. Since the outer surfaces of these outer hoods 10-12, 70, 71 can be formed smoothly, wind noise and running resistance can be reliably reduced, and the appearance of the vehicle connecting portion can be improved.

  Further, the outer hoods 10-12, 70, 71 are excellent in durability without fear of being damaged by the traveling wind, and are excellent in operation reliability without being vibrated by the traveling wind and generating noise. In addition, since the outer hoods 10-12, 70, 71 are in the form of strips, there is no risk of protruding outside the vehicle limit even in the event of a failure, and customers on the platform when the railway vehicle is stopped at the station. Excellent anti-falling function.

  In the side outer hood mechanism 6, the first movable outer hood 11 can be supported on the end wall 1 a by the first link mechanism 14, and the first movable outer hood 11 can be held in an aligned position in series with the fixed outer hood 10. Since it can move to the retracted position partially overlapping the inner side of the fixed outer hood 10, the configuration for supporting and moving the first movable outer hood 11 becomes very simple. Similarly, the second movable outer hood 12 can be supported by the first movable outer hood 11 by the second link mechanism 16, and the second movable outer hood 12 can be held in an aligned position in series with the first movable outer hood 11. Since the first movable outer hood 11 can be moved to a retracted position that entirely overlaps the inner side of the first movable outer hood 11, the configuration for supporting and moving the second movable outer hood 12 becomes very simple.

  Since the side outer hood mechanism 6 is mounted only on the end wall 1a of one vehicle 1 at the connecting portion of the vehicles 1 and 2, the side outer hood mechanism 6 only abuts on the end wall 2a of the counterpart vehicle 2. Therefore, the operation of connecting and separating the vehicles 1 and 2 is simplified. Since the side gap 3 is closed by the fixed outer hood 10 and the first and second movable outer hoods 11 and 12, it is possible to increase the amount of degeneration movement when the first and second movable outer hoods 11 and 12 move to the degenerated position. it can.

  Since the restriction mechanism 19 is provided, when the side gap 3 is reduced, the first movable outer hood is moved until the second movable outer hood 12 moves to a retracted position that entirely overlaps the inner side of the first movable outer hood 11. The first link mechanism 14 is locked so that 11 holds the aligned position. Thereby, the degeneracy operation | movement of the 1st, 2nd movable outer hoods 11 and 12 is stabilized, and the possibility that a resonance phenomenon may occur can be eliminated.

  In the roof outer hood mechanism 7, the roof-side movable outer hood 71 is supported on the end wall 1 a by the third link mechanism 72, and the roof-side movable outer hood 71 is held in an aligned position in series with the roof-side fixed outer hood 70. In addition, since it can be moved to a retracted position that partially overlaps the outside of the roof-side fixed outer hood 70, the configuration for supporting and moving the roof-side movable outer hood 71 becomes simple.

  Since the degenerated position of the roof-side movable outer hood 71 is a position that partially overlaps the outer side of the roof-side fixed outer hood 70, the side-side outer hood 71 moves when the roof-side movable outer hood 71 moves to the degenerated position. There is no interference with the first and second movable outer hoods 11 and 12 of the mechanism 6. Since the front-rear width of the roof-side movable outer hood 71 is formed larger than the front-rear width of the roof-side fixed outer hood 70, it is advantageous in securing the amount of degeneration movement of the roof-side movable outer hood 71.

Next, a modified example in which the above embodiment is modified will be described. In the following description, the same reference numerals are used for the same parts as in the above-described embodiment.
1] As shown in FIG. 14, the side outer hood mechanism 6A of the outer hood device 5A is mounted on both of the pair of end walls 1a and 1b facing each other of the connected vehicles 1 and 2, and each side outer hood is mounted. The mechanism 6A includes a fixed outer hood 10A fixed to the end walls 1a and 2a of the vehicles 1 and 2, a first movable outer hood 11A, and a first link mechanism 14A. The front and rear widths of these outer hoods 10A and 11A Are formed to have a front-rear width of about ¼ of the gap at the outer periphery of the vehicle body.

  The first movable outer hood 11A is disposed adjacent to the fixed outer hood 10A, and is arranged in an aligned position aligned in series with the fixed outer hood 10A and a degenerated position partially overlapping the inner side of the fixed outer hood 10A. It is possible to move. These first movable outer hoods 11A hold the aligned position when the knitted vehicle travels straight, and are pushed together when the knitted vehicle turns or when the side gap 3 shrinks during point switching point travel. Move toward the contracted position according to the degree of reduction. When the first movable outer hood 11A is in the aligned position, the outer surface thereof is a common surface with the outer surface of the fixed outer hood 10A.

In the side outer hood mechanism 6A, the support frame 13 is connected to the end walls 1a and 1b by the first link mechanism 14A, and on the inner peripheral side of the end face of the first movable outer hood 11A facing the first movable outer hood 11A. It is provided with a movable-side sliding contact plate 17A of low friction having a predetermined width, variable dynamic side sliding contact plate 17A between the first movable outer hood 11A of a pair of sliding contact. The first link mechanism 14A is configured in the same manner as the first link member 14. The second movable outer hood 12, the support beam 15, and the second link mechanism 16 are omitted.

  According to the outer hood device 5A, since the side outer hood mechanism 6A provided on the end walls 1a and 2a of the vehicles 1 and 2 can be made common, the connecting partner's vehicle can be freely selected when the vehicles are connected. In addition, the fixed outer hood 10A and the first movable outer hood 11A are light and slightly narrow with a width of about ¼ of the width of the side gap 3, and thus the link mechanism is made compact. Can be lighter. In addition, when the side gap 3 is reduced during turning, the pair of first movable outer hoods 11A moves to the retracted position, so that a sufficient amount of contraction can be ensured.

2] As shown in FIG. 15, the outer hood device 5B is provided only on one of the pair of end walls 1a, 1b of the coupled vehicles 1, 2, but the side portion thereof. The outer hood mechanism 6B is basically the same structure as the side outer hood mechanism 6A of the outer hood device 5A, and has a fixed outer width that is larger than the fixed outer hood 10 and the first movable outer hood 11A. The hood 10B and the first movable outer hood 11B are provided, and the fixed outer hood 10B and the first movable outer hood 11B each have a front-rear width that is about a half of the front-rear width of the side gap 3. 10B and the first movable outer hood 11B are connected by the first link mechanism 14B, and when the side gap 3 is reduced, a sufficient amount of degeneration of the first movable outer hood 11B is secured.
