Abstract
A toggle-rod-boosted electromechanical brake consists of a brake disc, a caliper, a support, a first pin shaft assembly, a connecting component, a second pin shaft assembly, a first connecting rod, a third pin shaft assembly, a fourth pin shaft assembly, a second connecting rod, a fifth pin shaft assembly, a motor speed reducer assembly, a first friction plate, a second friction plate, a third connecting rod, a sixth pin shaft assembly, a ball screw assembly, a push cylinder and an opening cylinder sleeve. The toggle-rod-boosted electromechanical brake can effectively save cost and reduce the installing space, has the advantages of low energy consumption, high response speed, convenience in maintenance, simple structure, low cost and the like, can effectively use a boosting mechanism for rapidly increasing the braking torque, can conveniently implement ABS, EDB and other integrated control, and improves the traffic safety and the brake reliability.
Description
technical field [0001] The invention relates to a vehicle brake, in particular to a toggle booster 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 brakin...
