Description

Bending spring piece

Technical Field

The utility model relates to a spring piece for an automobile brake system, in particular to a bending spring piece.

Background

With the rise of the automobile manufacturing industry, automobile braking systems are also receiving increasing attention. The brake caliper of the brake system of the automobile mainly comprises parts such as a caliper body, a caliper body bracket, a piston, a sealing ring, a brake block, a spring piece and the like, and the brake principle is that the piston pushes the brake block to move forward along a guide rail under the hydraulic pushing, and a main brake block and an auxiliary brake block lock a brake disc of the automobile, so that the automobile is braked.
