Background
During the braking process of the brake caliper, the friction plate can move along the support guide groove and is limited by the support limiting surface to generate braking force. In the braking process, the friction plate moves forwards, and when the friction plate is in the limit of abrasion, the back plate needs to be ensured to be in the support broach slot and cannot fall off.
The traditional friction plate is a straight plate, so that when the friction plate is worn to the limit, the thickness of the back plate needs to be increased in order to ensure that the back plate still needs to be in the support broach slot and cannot fall off, and the weight and the cost of the back plate are increased.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 5, a bracket 3 is arranged in a shell 1 of the brake caliper to connect an inner friction plate 2 and an outer friction plate 4, the structure of the inner friction plate 2 is consistent with that of the outer friction plate 4, and the inner friction plate 2 and the outer friction plate 4 are arranged oppositely; the inner friction plate 2 comprises a friction material structure, a damping reed, a silencing sheet and a back plate, the front side of the back plate 8 is connected with the silencing sheet 7, the rear side of the back plate 8 is connected with the friction material structure 6, and the damping reeds 5 are respectively riveted on the guide hammer heads at the left end and the right end of the back plate 8.
The damping reed 5 is of a U-shaped bending structure, the damping reed 5 comprises a riveting surface, a U-shaped bending structure and a damping surface, the riveting surface 54, the U-shaped bending structure 52 and the damping surface 53 are connected and integrally formed, the riveting surface 54 is provided with a riveting hole 51, and the riveting surface 54 and the damping surface 53 are arranged perpendicularly to each other.
The guide hammers at the left end and the right end of the back plate 8 are bending structures 21.
The damper surface 53 of the damper reed 5 is bonded to the striking surfaces 41 at the left and right ends of the back plate 8.
Two sides of the inner friction plate 2 and the outer friction plate 4 are respectively riveted with 1 damping reed 5. The inner friction plate 2 and the outer friction plate 4 move in the bracket broach slot 32. The guide hammers at the left and right ends of the back plate 8 are in the form of the bending structures 21, so that the guide length in the support broach slot 32 is increased compared with the traditional straight plate. The support 3 of the brake caliper is fixed, in the braking process, the inner friction plate 2 and the outer friction plate 4 move in the support broach slot 32, and due to the backward bending of the back plate 8, the abrasion limit of the friction material structure 6 is increased on the premise of not increasing the thickness of the back plate 8, and the length required by the friction plates is fixed.
When such a structure is adopted, the structure of the shock absorbing reed 5 can be adopted when overcoming the impact sound during braking. The riveting holes 51 on the riveting surface 54 can ensure that the damping surface 53 of the damping reed 5 is attached to the impact surface 41 of the back plate 8, so as to be riveted on the two ends of the back plate 8 of the friction plate. Due to the U-shaped bent structure 52, the stress of the deformation of the shock absorbing reed 5 can be released during the impact, thereby ensuring the durability of the shock absorbing reed 5.
Because the back plate 8 adopts a bending form, the guiding length of the back plate 8 on the bracket 3 is increased when the abrasion limit of the friction plate is increased. Due to the bending of the back plate 8, if impact noise of the back plate 8 and the support 3 occurs, the impact noise is reduced by adopting a riveting damping reed 5 mode, the damping reed 5 can be made into a standard part, and the damping reed can be directly used regardless of which project has a problem without additional development.
