Description

Technical Field

[0001] The utility model relates to the technical field of automotive braking systems, and particularly relates to a spring piece with stable performance. Background Art

[0002] The function of the automotive brake spring piece is to prevent the parts on the shaft or in the hole from moving left and right, and at the same time, it is a circlip used to indicate that the brake pad is worn out. When the brake pad is consumed to the circlip, the circlip will rub against the brake disc, making a metal friction sound to remind the vehicle owner to replace the brake pad. The performance of the spring piece affects the stability of automotive braking. The existing automotive spring pieces are prone to deformation and fracture, and the structural design is relatively complex, resulting in poor stability and affecting the braking performance of the vehicle.
