Eccentric brake mechanism

Abstract

The invention relates to the technical field of brake mechanisms, and discloses an eccentric brake mechanism. The eccentric brake mechanism comprises a fixed shaft sleeve, friction set pieces are fixedly installed on one side of an inner cavity of the fixed shaft sleeve, a set of fixed discs are separately and fixedly installed on the front side and the rear side of the fixed shaft sleeve, and eccentric holes staggered with the central axis of the fixed discs are formed in the fixed discs. The eccentric holes movably sleeve a transmission main shaft penetrating through the front end and the rear end of the fixed shaft sleeve, and a transmission disc set fixedly sleeves the middle of the outer surface of the transmission main shaft and located in the inner cavity of the fixed shaft sleeve. Due to the arrangement of a plurality of groups of circulating grooves, fixed sliding grooves and brake friction modules on the transmission disc set, when the brake mechanism conducts brake operation, the brake friction modules on the brake mechanism make contact with friction set pieces one by one in the rotating direction of the transmission disc set, and corresponding friction brake force is generated; and therefore, the brake friction modules which are not in contact with the friction set pieces have the cooling time, and the phenomenon of heat fading caused by overheating is avoided.

Description

technical field [0001] The invention relates to the technical field of brake mechanisms, in particular to an eccentric brake mechanism. Background technique [0002] The main function of a car brake device is to slow down or stop a moving car, or keep a stopped car still. As an important indicator of car safety performance, its braking performance can directly affect the vehicle and its driving performance. passenger safety. [0003] At present, the braking action on existing automobiles is mainly realized by drum brakes and disc brakes, but both brakes have certain technical defects. Although the braking performance of drum brakes is better than that of disc brakes, but The heat dissipation effect of drum brakes is poor. During the long-term braking process, the brake pads will suffer from thermal degradation due to overheating, which will lead to brake failure. Although the disc brakes have better heat dissipation effects, their braking performance It is not as good as t...

AI Technical Summary

Problems solved by technology

[0006] The invention provides an eccentric braking mechanism, which can provide good braking performance for the automobile, effectively shorten the braking distance of the automobile, and have better heat dissipation effect and less prone to heat decay, and are safe and reliable. And the advantages of higher reliability, solve the existing technical defects of the brakes on the car, although the braking performance of the drum brake is better than that of the disc brake, but the heat dissipation effect of the drum brake is poor, and it will be used for a long time In the process of moving, the brake pads will experience thermal decay due to overheating, which will lead to brake failure; while disc brakes have a better heat dissipation effect, but their braking performance is not as good as that of drum brakes. Provide a strong braking force, which in turn leads to a longer braking distance and a greater potential safety hazard
