Push disc position structure of disc brake

Abstract

The invention provides a push disc position structure of a disc brake. The push disc position structure comprises a bracket, a caliper body, push discs, a friction assembly and a brake disc, the two push discs are symmetrically arranged on the caliper body, the friction assembly is composed of an outer friction plate and an inner friction plate, the outer friction plate and the inner friction plate are symmetrically arranged, the brake disc is arranged in the bracket, and the brake disc is located between the outer friction plate and the inner friction plate. After the size of the caliper body is increased, a friction plate with the large area and the large size is carried, the friction plate is made to be more wear-resistant, the service life of the friction plate is prolonged, the replacement frequency is reduced, under the condition that the friction coefficient and the brake torque are not changed, the heat capacity of the large friction plate is increased, in the braking process, heat dissipation of the friction plates is fast, the influence of heat fading on braking force is reduced, and therefore the braking effect of a novel disc brake is more obvious.

Description

technical field [0001] The invention relates to the technical field of disc brakes, in particular to a disc brake push disc position structure. Background technique [0002] Disc brakes have the advantages of good thermal stability, stable braking torque, uniform pressure distribution on friction plates, and low noise. Its working surface is flat and conducts heat on both sides. The rotating disk is easy to cool, not easy to deform, and has relatively stable braking performance. Therefore, it is widely used in the automotive industry. Disc brakes not only have a complex external structure, but also have high shape and position accuracy of the parts, and the safety performance is directly related to the braking performance of the vehicle and the life safety of the driver. [0003] When the disc brake is working, under the action of air pressure, the push plate presses the friction plate against the high-speed rotating brake disc, thereby generating friction between the frict...

AI Technical Summary

Problems solved by technology

[0004] Traditional disc brakes are equipped with small friction plates and the friction contact surface is small, so the service life of the friction plates is short, the replacement cycle is short, the braking effect is not good, and the wear of the friction plates is large, and the replacement frequency is high. high cost
