Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-3, the utility model provides a EMUs brake lining, including clutch blocks 1, mounting panel 3, adjuster 2 and spring catch 4, the connecting axle 11 of clutch blocks 1 passes adjuster 2 and mounting panel 3 and 4 joints of spring catch, installs damping shim 5 with the position of braking clamp contact in mounting panel 3's brake lining mounting groove 31.

The utility model discloses install damping shim 5 with the position of braking clamp contact in the brake lining mounting groove 31 of EMUs brake lining mounting panel 3. The influence of brake impact on the brake pad assembly can be effectively reduced in the brake process, and the probability of fatigue damage of the brake pad assembly can be reduced. The utility model has the advantages of simple structure, need not to change the production technology and the structure size of EMUs brake lining, the commonality is stronger, suitable extensive popularization.

The utility model provides a vibration damping shim 5 can be installed in brake lining mounting groove 31 through multiple means, the preferred, vibration damping shim 5 can be through the mode of pressurization heat bonding or through the cold glue of high temperature resistant bonding on mounting panel 3. In this embodiment, the brake pad is adhered to the brake pad mounting groove 31 by pressing and thermal adhering.

The utility model discloses in only set up shock attenuation material that buffer layer 53 can be commonly used for the braking field, can realize through purchasing the means outward, buffer layer 53 is woven by polyester fiber and warp lun fibre in this embodiment and is formed, and not only shock attenuation performance is better, and high temperature resistance can have very excellence moreover, for increase shock absorber's rigidity, shock absorber 5 still includes the first rubber layer 52 of stack-up together in the embodiment of easily bonding, bonds through high temperature resistant glue between first rubber layer 52 and the buffer layer 53.

In order to prevent heat generated during braking from being transferred to the brake, the shock absorbing pad 5 in this embodiment further includes a heat insulating layer 54, and the heat insulating layer 54 is adhered to the outer side of the first rubber layer 52 and can prevent frictional heat generated during braking from being transferred to the brake caliper.

The utility model provides a vibration damper 5 can bond in brake lining mounting groove 31 through scribbling the viscose in addition, nevertheless for the convenience of installing in this embodiment vibration damper 5 still including can bond the adhesive linkage 51 on mounting panel 3, can directly pressurize the mode bonding of hot bonding and bond in brake lining mounting groove 31.
