Description

  The present invention relates to a brake lining used, for example, in a disc brake device for a railway vehicle, and more particularly, to an improvement for realizing cost saving and productivity improvement by relaxing processing accuracy of parts used.

  A disc brake device includes a disc rotor fixed to an axle, a torque receiving plate disposed opposite to the disc rotor, and an actuator that drives the torque receiving plate to advance and retract toward the disc rotor. Sliding friction when the torque receiving plate is advanced to the disk rotor side and the lining member is pressed against the disk rotor. The brake caliper is fixed and the lining member is assembled to the disk rotor side surface of the torque receiving plate. Thus, a braking force is generated.

  In the disk brake device for railway vehicles, since the disk rotor and brake lining are large, if the lining member to be pressed against the disk rotor is formed as an integral part, it is non-contact due to undulations generated in the disk rotor due to frictional heat, etc. Therefore, the stable friction area cannot be maintained, and stable braking characteristics cannot be obtained.

  Therefore, in order to solve such problems, a large number of second link plates are laid on a substantially flat surface on the torque receiving plate, and a large number of first link plates are attached to each other on each second link plate. A plurality of lining members are laid independently on each first link plate so as to be able to swivel independently of each other, and each first link plate is moved by moving the torque receiving plate toward the disk rotor. A brake lining having a configuration in which each of the upper lining members is brought into contact with a disk rotor has been proposed (see, for example, Patent Document 1).

  In the brake lining having such a configuration, each of the lining members divided into small parts follows the undulations on the surface of the disk rotor and makes contact with the surface of the disk rotor by individual turning operations, so that a stable friction area is maintained. , Stable braking characteristics can be maintained.

Japanese National Patent Publication No. 10-507250

  By the way, in the brake lining described in Patent Document 1, the position regulation of the lining member on the torque receiving plate is spherical contact in both the direction parallel to the surface of the lining member and the direction orthogonal to the surface of the lining member. The lining member is pivoted by a first universal joint that is pivotally connected to the first link plate.

  In addition, the position of the first link plate on the second link plate is also swiveled by the spherical contact portion in both the direction parallel to the surface of the lining member and the direction orthogonal to the surface of the lining member. The second universal joint is freely connected to the second link plate.

  As a result, all braking torques acting on the lining member during braking are transmitted in sequence from the lining member to the first link plate and from the first link plate to the second link plate via the spherical contact portion of the universal joint. And finally, it will be transmitted to the torque receiving plate to which the second link plate is connected, and each universal joint must be robust and the spherical contact portion of each universal joint must be processed with high precision. In some universal joints, an excessive load is concentrated, which may cause damage.

  However, since there are many places where universal joints are used, all universal joints must have a robust structure, and the spherical contact portion and the mating contact portion with which the spherical contact portion contacts must be processed with high accuracy. As a result, there is a problem that the processing cost of parts increases, resulting in an increase in brake lining costs and a decrease in productivity.

  Further, in the brake lining described in Patent Document 1, when vibration is applied, the second link plate and the first link plate on the torque receiving plate move independently of each other, and a large relative movement occurs between the link plates. In such a case, since a large impact load acts on the universal joint, there is also a problem that it is difficult to improve the earthquake resistance.

  Therefore, the object of the present invention is to solve the above-mentioned problems, and it is possible to realize cost savings and productivity improvements by reducing the machining accuracy of the parts used, reducing the number of lining members to be used, etc. Furthermore, it is providing the brake lining which can improve earthquake resistance.

The above object is achieved by the following configuration.
A guide plate facing a disk rotor surface and having a large number of lining members assembled thereto, and a first link that presses at least two of the lining members while maintaining that the lining members can pivot. A plate, a second link plate that simultaneously presses the first link plate and the other one of the plurality of lining members, and is fastened to the disk rotor by sandwiching the guide plate and the link plates. A brake lining of a disk brake device, wherein the lining member on each link plate is brought into contact with the disk rotor by movement of the torque receiving plate toward the disk rotor side.
Each lining member is fitted in a guide hole on a guide plate fixed to the torque receiving plate via a cover so as to be able to turn, and a braking torque acting upon contact between the disk rotor and the lining member is applied to the guide plate. A torque transmission ring that transmits to the shaft, and is provided at a tip of a shaft portion that passes through the torque transmission ring, and abuts freely on either the first link plate or the second link plate, and A spherical contact portion that receives a pressing force from the torque receiving plate,
The cover is provided with a guide portion that restricts movement of the second link plate in the surface direction within a predetermined amount,
The first link plate and the second link plate are provided with engagement means for restricting relative movement in the surface direction within a predetermined amount.

In the brake lining configured as described above, the position of the lining member relative to the torque receiving plate is regulated by fitting the torque transmission ring provided on the lining member with the guide plate in the direction parallel to the disk rotor surface of the lining member. Further, in the direction perpendicular to the disk rotor surface of the lining member, the contact is made between the spherical contact portion provided at one end of the lining member and the link plate.
Accordingly, the braking torque that acts on the lining member during braking is transmitted from the torque transmission ring to the guide plate, and is directly transmitted to the torque receiving plate that is fixed via the cover.
On the other hand, the pressing force for pressing the lining member against the disk rotor is spherical contact with the second link plate or the first link plate from the torque receiving plate to the second link plate, from the second link plate to the first link plate. It is transmitted in order to each lining member that is in contact with the part.

That is, the member that receives the braking torque from the lining member and the member that receives the pressing force from the lining member are set separately, and the braking torque that is a large load does not act on the spherical contact portion that is difficult to process.
Therefore, the turning joint that transmits the pressing force in the direction orthogonal to the disk rotor surface via each spherical contact portion is a robust and highly accurate engagement structure like the conventional universal joint that transmits the braking torque. Therefore, it is possible to reduce costs and improve productivity by reducing the machining accuracy of each component constituting the turning joint.

  Further, the lining members are individually separated from each other by a turning operation of the second link plate with respect to the torque receiving plate, a turning operation of the first link plate with respect to the second link plate, and a turning operation of the lining member with respect to each of these link plates. The direction of contact with the surface can be adjusted. Therefore, each lining member follows the undulations on the surface of the disk rotor and makes stable contact with the surface of the disk rotor by individual swiveling motions. Therefore, a stable friction area can be obtained without being affected by the undulations on the surface of the disk rotor. Maintaining stable braking characteristics.

  Further, in the brake lining configured as described above, when vibration is applied, the movement of the second link plate on the torque receiving plate is restricted by the guide portion mounted on the cover, and the first link plate is also engaged with the second link plate. Since the relative movement is restricted, the amount of movement between the link plates can be kept small, and the impact load caused by the movement in response to the vibration can be reduced, so that the earthquake resistance can be improved.

The above brake lining 1 is assembled in the procedure shown in FIG.11 and FIG.12.
That is, first, as shown in FIGS. 11A to 11C, the lining member 13 is assembled to the guide holes 17 of the guide plates 11A and 11B by the joint mechanism 21 to complete the lining assemblies 9A and 9B. .
Next, as shown in FIGS. 11D to 11F, the first link plate 7 and the second link plate 5 are assembled to the back surfaces of the lining assemblies 9A and 9B.
Next, as shown in FIG. 12A, an assembly is formed by screwing the covers 4A and 4B on the torque receiving plates 3A and 3B, and the assembly is shown in FIGS. 12B and 12C. Thus, the completed form shown in FIG. 2 is obtained by screwing the guide plates 11A and 11B from above the second link plate 5.

In the brake lining 1 described above, the position restriction of the lining member 13 with respect to the torque receiving plates 3A and 3B is limited in the direction parallel to the disk rotor surface of the lining member 13 and the torque transmission ring 23 provided on the lining member 13. And the guide plates 11A and 11B are fitted together, and in the direction perpendicular to the disk rotor surface of the lining member 13, the spherical contact portion 27c provided at one end of the lining member 13 and the link plates 5, 7 By contact with
Accordingly, the braking torque acting on the lining member 13 during braking is transmitted from the torque transmission ring 23 to the guide plates 11A and 11B, and the guide plates 11A and 11B are fixed via the covers 4A and 4B. , 3B is transmitted directly.
On the other hand, the pressing force that presses the lining member 13 against the disc rotor is applied from the torque receiving plates 3A and 3B to the second link plate 5, from the second link plate 5 to the first link plate 7, and to the second link plates 5 as well. Alternatively, the light is transmitted in order to each lining member 13 in which the spherical contact portion 27 c is in contact with the first link plate 7.

That is, the member that receives the braking torque from the lining member 13 and the member that receives the pressing force from the lining member 13 are set separately, and the braking torque that is a heavy load does not act on the spherical contact portion 27c that is difficult to process. .
Therefore, the turning joint portion that transmits the pressing force in the direction orthogonal to the disk rotor surface via the spherical contact portions 27c, 29a, and 48b is robust and high like the conventional universal joint that transmits the braking torque. It is not necessary to use an accurate engagement structure, and cost reduction and productivity improvement can be realized by easing the machining accuracy of each component constituting the turning joint.

  Further, each lining member 13 is a turning operation of the second link plate 5 with respect to the torque receiving plates 3A, 3B, a turning operation of the first link plate 7 with respect to the second link plate 5, and a lining member with respect to each of these link plates 5, 7. By the 13 swiveling operations, the contact directions to the disk rotor surface can be adjusted individually. Therefore, each lining member 13 follows the undulations on the surface of the disk rotor and makes a stable contact with the surface of the disk rotor in an individual turning motion, so that the stable friction area is not affected by the undulations on the surface of the disk rotor. And stable braking characteristics can be maintained.

  Further, in the brake lining 1 having the above-described configuration, when vibration is applied, the second link plate 5 on the torque receiving plates 3A and 3B is moved by fitting with an opening 47 as a guide portion mounted on the covers 4A and 4B. Since the relative movement of the first link plate 7 is also restricted by the engagement of the first link plate 7 with the second link plate 5 via the link rod 31, the amount of movement between the link plates 5 and 7 can be suppressed to a small level. Since the action of the impact load due to the movement in response to is reduced, the earthquake resistance can be improved.

  In addition, the specific structure of the joint mechanism 21 which couple | bonds the lining member 13 with guide plate 11A, 11B is not restricted to the structure shown in the said embodiment. For example, instead of the joint rod 27, it is also possible to use a rivet that crimps the end. By using a rivet, the clip 28 can be omitted and the number of parts can be reduced.

  Further, in the brake lining of the disc brake device of the present invention, the specific structure of the guide portion provided in the covers 4A and 4B in order to restrict the movement of the second link plate 5 in the surface direction within a predetermined amount is as described above. The opening 47 is not limited to that shown in the embodiment. For example, instead of the opening 47, an engagement structure with a dedicated engagement pin may be adopted.

  Further, the structure of the engaging means that restricts the relative movement of the second link plate and the first link plate in the surface direction within a predetermined amount is not limited to the configuration shown in the above embodiment. For example, the second link plate 5 and the first link plate 7 may be configured to restrict mutual movement by fitting the concavo-convex portions formed integrally with each other. It is possible to eliminate the use of the link rod 31 and reduce the number of components.
