Abstract

A combined electronic mechanical brake is composed of a motor, a bracket, a speed reducer, a first clamp, a first friction plate, a second friction plate, a brake disc, a third friction plate, a second clamp, a fourth friction plate, a fixed bracket, a thrusting plate, a first ball bar, a sleeve, a second ball bar, a fixed bolt, a baffle ring, a thrusting ball, a screw rod, a nut, a first thrusting cylinder, a wear resistant sleeve, a second thrusting cylinder and a positioning bolt. When in use, the combined electronic mechanical brake can effectively reduce the motor power and save mounting space, has the advantages of low energy consumption, high response speed, convenience in maintenance, simplicity in structure, low cost and the like, can effectively utilize a force amplifying mechanism to quickly increase the braking torque, so as to conveniently realize ABS, EDB, and other integrated control, adopts multiple friction plates to effectively reduce the temperature rise during braking, increase the braking efficiency, and improve the driving safety and the braking reliability.

Description

technical field [0001] The invention relates to a vehicle brake, in particular to a composite electromechanical brake. Background technique [0002] The brake is an important part of the car, and it is a vital safety device. The quality and performance of the brake affect the driving safety. With the development of society and the increase of the number of vehicles in society, the excellent braking performance of vehicles has attracted widespread attention from the society, and higher requirements have been put forward for driving safety. [0003] Nowadays, the vehicle brake mainly adopts the traditional hydraulic braking method. The brake pipeline is long and there are many valve components, which often leads to too long hysteresis time in hydraulic transmission. Coupled with the hysteresis characteristics of the mechanical brake structure, it is easy to cause braking hysteresis. This will undoubtedly increase the braking distance and reduce safety; the current braking sys...
