High-efficiency air-cooling forced heat dissipation brake pad and manufacturing method thereof

Abstract

Ventilation duct type layout is adopted, porous titanium carbide in a friction material is combined, the heat dissipation performance is improved, dust and noise are low, the ABS intervention peak braking distance is changed, the abrasion performance of the brake pad is improved, braking is linearly smooth, and the service life is effectively prolonged. And through data calculation, the efficiency is effectively improved by 15-25%. In the braking process, after the heat dissipation grooves make contact with the brake disc, a closed heat dissipation channel covering the surface of the brake disc is formed, and after hot air and dust are collected through the vertical heat dissipation well, heat is rapidly released through the heat dissipation channel under the action of the axial flow fan, so that the effects of forced heat dissipation and prevention of dust falling on tires are achieved.

Description

technical field [0001] The invention belongs to an automobile brake pad with fast heat dissipation, in particular to a high-efficiency air-cooled forced heat dissipation brake pad and a manufacturing method thereof. Background technique [0002] Brake pads are automotive brake linings, which are friction materials fixed on the brake drum or disc that rotates with the wheels. The friction linings and friction pads are subjected to external pressure to produce friction effects. And the friction between the tire and the ground, the kinetic energy of the vehicle is converted into heat energy after friction, so as to achieve the effect of decelerating or stopping the vehicle. Therefore, the brake pad is a vital part of the car and is related to personal safety. We found that, in road conditions such as mountain road downhill, the brakes brake continuously and the temperature rises rapidly, and the brake disc may reach a temperature of four, five hundred or even seven hundred degr...

Problems solved by technology

The braking distance will increase, the braking ability of the brake pads will become worse, and even the thermal recession will be severe, resulting in brake failure

[0003] In addition, the brake pads in some existing technologies contain a large number of hard spots and impurities, which will pull out many grooves on the surface of the brake disc, and there are technical problems such as brittle edges and corners.

[0004] For a long time, the company has been committed to solving the above problems, and invented a high-performance ternary composite brake pad (patent number 201610064026.1). Although the thermal recession resistance is better, many imported materials are used, and the process of the ternary structure is relatively complicated. , so the cost is high
