Problems solved by technology

Existing brake pads will generate a lot of heat locally when the brake pads and brake discs rub against each other. Although the brake pads themselves have a heat insulation layer, they only have heat insulation functions for themselves and do not have heat dissipation functions. The high temperature generated by braking will cause the brake pads to expand and deform, which will affect the close fit between the brake pads and the brake disc surface, lose the stability of the brakes, and cause accidents

Abstract

The invention relates to a brake block with heat dissipation and silencing, including a backplane, an insulation layer and a friction block. A first heat sink, a second heat sink, through slots and heat dissipation fins are arranged on the friction block. A thermal conductive layer is arranged between the two through slots, so that the heat generated by the brake block is rapidly dissipated through the heat sinks and heat dissipation fins, thereby improving the heat dissipation efficiency and braking stability of the brake block body. The bottom surfaces of the first heat sink and the second heat sink are respectively fixedly connected with a silencing layer, thereby making the silencing layer cover a large area and having a good silencing effect.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a heat-dissipating and sound-absorbing brake pad. Background technique [0002] Automobile brake pad refers to the friction material fixed on the brake disc rotating with the wheel. The friction block on the brake pad is subjected to external pressure to generate friction, so as to achieve the purpose of decelerating the vehicle. The brake pad is generally composed of a back plate and a heat insulation layer. It is composed of a friction block, and the purpose of the heat insulation layer is heat insulation, which is composed of materials that do not conduct heat. Existing brake pads will generate a lot of heat locally when the brake pads and brake discs rub against each other. Although the brake pads themselves have a heat insulation layer, they only have heat insulation functions for themselves and do not have heat dissipation functions. The high temperature generated by br...
