A Booster Electromagnetic Mechanical Brake

Abstract

A reinforcement type electromagnetic mechanical brake is composed of a movable board, a disc spring, a fixing shell, a coil, a first support, a mandrel pushing rod, a first hinge pin assembly, a second hinge pin assembly, a swing arm, a first nut, a tightly-pulling rod, a second nut, a pair of first calipers, a first friction plate, a brake disc, a second friction plate, a third hinge pin assembly, a third friction plate, a pair of second calipers, a fourth friction plate, a pushing cylinder, a second support, a thrust ball, a thrust board, a locating bolt, a first pulling rod, a sleeve, a second pulling rod, a baffle ring, a bolt and an extruding board assembly. The reinforcement type electromagnetic mechanical brake has the advantages that cost is effectively saved, the installation space is saved, energy consumption is low, the response speed is high, repair is convenient, the structure is simple, cost is low, the braking torque can be rapidly improved through effective use of a force-amplifier, integrated control over an ABS, an EDB and the like can be achieved conveniently, brake temperature rise can be effectively reduced through the friction plates, the braking efficiency is improved, and the traveling safety and the braking reliability are improved.

Description

technical field [0001] The invention relates to a vehicle brake, in particular to a booster electromagnetic mechanical 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 brak...

However, there is a contradiction between motor power and installation space in this mechanism, and a contradiction between deceleration and torque increase and response speed. During frequent braking, the kinematic mechanism will bear a large torque and shorten its life.
