Meshed type high-temperature resistant brake pad

Abstract

The invention relates to a meshed type high-temperature resistant brake pad. The meshed type high-temperature resistant brake pad comprises a base body bottom plate and a friction material block. A friction material main contact surface is arranged on one side of the base body bottom plate, a friction material auxiliary contact surface is arranged on the other side of the base body bottom plate, a boss is arranged, facing towards the direction of the friction material main contact surface, on the base body bottom plate, a plurality of punched holes are formed in the base body bottom plate, the friction material block and the friction material main contact surface are connected in a contact mode, the friction material block penetrates through a part of the punched holes in the boss and is filled into a concave part formed in one side of the friction material auxiliary contact surface, and then the friction material block and the base body bottom plate are meshed together. The friction material block and the base body bottom plate are meshed, pressed and clamped together, the brake effect of the brake pad under the high-temperature condition is guaranteed, driving brake safety of a car is improved, and the high-temperature resistant performance of the brake pad is achieved; the friction material block and a flanging of the base body bottom plate are pressed together, and therefore the service life of the brake pad is prolonged; a punching flanging process is adopted in the base body bottom plate, and therefore mechanical strength of the base body bottom plate is improved.

Description

technical field [0001] The invention relates to automobile braking technology, in particular to a occlusal type high temperature resistant brake pad. Background technique [0002] Automobile brake pads are an important safety component of the automobile braking system. The performance of the brake pads directly reflects the quality of the car's braking effect, which is related to the safety of life and property of the car drivers and passengers. [0003] Automobile brake pads are composed of three parts: base plate, adhesive layer and friction material block. The base plate is straight. The manufacturing process is as follows: punch out a base plate according to the design requirements, coat a layer of adhesive on the flat base plate, then put the friction material mixed according to the formula into the cavity of the press mold, and press together with the base plate to form a whole , made of brake pads. Existing brake pads, when the vehicle is driving downhill on a moun...

AI Technical Summary

Problems solved by technology

Existing brake pads, when the vehicle is driving downhill on a mountain road, the brakes are continuously braked, and the temperature rises rapidly. The brake disc may reach a high temperature of 400-500°C or even 700°C, and the adhesive layer of the brake pad may will be melted, the adhesive force between the interface between the base plate and the adhesive layer, and the interface between the adhesive layer and the friction material block will drop sharply, and even cause the base plate and the friction material block to fall off, causing serious accidents

In addition, the friction material block of the current automobile brake pad is completely exposed outside, which is easily damaged by collision and reduces its service life.
