Heat pipe even-temperature heat dissipation device used for vehicle disc brake

Abstract

The invention discloses a heat pipe even-temperature heat dissipation device used for a vehicle disc brake. The device comprises a brake disc composed of brake flanges arranged oppositely. Heat pipe arrays are arrayed on the opposite faces of the two brake flanges respectively in an annular shape, and the heat pipe arrays are fixed to the brake flanges in a surface contact mode through heat pipe grooves formed in the brake flanges. According to the device, it is unnecessary that an extra auxiliary power source is used for maintaining operation of heat pipes, extra motion components do not need to be arranged inside the brake disc, in this way, reliability is high, and it is avoided that the motion components fail because of abrasion, collision and others. The structure of an existing brake disc is sufficiently used, the heat pipe grooves are formed in air ducts between the opposite surfaces of the brake flanges, people do not need to change the overall structure of the brake disc, adaptability is high, the technology is simple, and the cost is low. According to the device, the technology means is simple and easy and convenient to implement, the even-temperature performance of the brake disc is good, the surface average temperature and the transient temperature are low, the structure is simple, the reliability is high, and installing is convenient.

Description

technical field [0001] The invention relates to a disc-type vehicle brake, in particular to a heat-pipe heat-dissipating device for the disc-type vehicle brake. Background technique [0002] With the rapid development of highways and the increasing number of vehicles, traffic accidents are also increasing. According to relevant survey statistics, in the traffic accidents caused by the problems of the vehicle itself. [0003] The braking system is an important part of the vehicle, which directly affects the safety of the vehicle. Among them, the disc brake passes through a disc (that is, the brake disc) that is fixed to the tire and rotates at the same speed. When braking, the oil pressure is used to push the piston in the brake caliper to generate braking force, and contact with the "disc" to generate friction, and finally make the vehicle Stop, because of its light weight, simple structure, convenient adjustment, stable braking effect, good thermal stability and water sta...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to overcome the shortcomings and deficiencies of the above-mentioned prior art, and provide a heat pipe heat dissipation device for disc vehicle brakes, which effectively solves the problem that the surface temperature of the disc brake disc of the disc vehicle brake in the prior art exists along the radial direction. Obvious gradient, and the instantaneous temperature and average temperature are high, resulting in obvious thermal degradation of brake braking performance
