Description

Technical Field

[0001] The utility model relates to the technical field of friction plates, in particular to a friction plate with an anti-deformation structure for a muffler plate. Background Art

[0002] Automobile disc brake friction pads include friction blocks and steel backs. In order to reduce braking noise, a silencer with a specific structure is added. Usually, the silencer is connected to the steel back. The silencer, steel back and friction block together constitute the friction plate assembly. The matching structure of the steel back and the silencer is riveted and bonded.

A group of crescent grooves are symmetrically provided on the noise-absorbing plate; the crescent grooves are located at the edge of the contact position between the piston and the noise-absorbing plate during braking to achieve heat dissipation. The beneficial effects of the utility model are: solving the abnormal noise problem caused by the failure of the noise-absorbing plate; increasing the service life of the noise-absorbing plate; improving the brake performance and enhancing the driving experience.

[0004] In actual use, it is found that the crescent groove allows air to dissipate heat, preventing the silencer glue from melting due to heat accumulation. However, when the silencer is under pressure, the silencer is prone to warping and deformation. Therefore, we propose a noise-proof friction plate with an anti-deformation structure to solve the above problem. Utility Model Content
