Problems solved by technology

When braking, the friction block is used to absorb or transmit power. The friction block will generate a large amount of heat locally, causing thermal stress on the surface of the friction plate. When the thermal stress exceeds the yield limit, the friction block will deform. When the deformation area reaches a certain value, The contact area of ​​the friction block is reduced sharply, causing the friction block to lose its stability, resulting in burning and warping.

Abstract

The invention discloses a brake pad which comprises a steel plate, a friction block and a bonding heat insulation layer between the steel plate and the friction block. The brake pad is characterized in that a heat dissipation layer is arranged between the bonding heat insulation layer and a non-friction face of the friction block, an arc-shaped groove is arranged on a friction face of the friction block, the width of the arc-shaped groove is 1mm, the depth of the arc-shaped groove is 0.3mm, and the heat dissipation layer is composed of heat dissipation sheets. The design of the heat dissipation layer is favorable for rapid emission of heat produced on the friction block, service life of the friction block is prolonged, the design of the arc-shaped groove on the surface of the friction face quickens heat dissipation of the friction block, friction coefficients of the friction block are improved, and abrasion of the friction block is reduced.

Description

[0001] technical field [0002] The invention relates to a brake pad, in particular to a brake pad used in automobiles, and belongs to the field of automobile brake parts. Background technique [0003] Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. When braking, the brake pads are squeezed on the brake disc or brake drum to generate friction, so as to achieve the purpose of vehicle deceleration and braking. When braking, the friction block is used to absorb or transmit power. The friction block will generate a large amount of heat locally, causing thermal stress on the surface of the friction plate. When the thermal stress exceeds the yield limit, the friction block will deform. When the deformation area reaches a certain value, The contact area of ​​the friction block is sharply reduced, causing the friction block to lose its stability, resulting in burning and warping. Contents of the invention [0004] In view of the ...
