Title:
TESTING BENCH FOR AUTOMOBILE ELECTRO-MECHANICAL BRAKE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/028927
Kind Code:
A1
Abstract:
A testing bench for an automobile electro-mechanical brake system, comprising a testing bench rack (2), and disposed on the testing bench rack (2), a simulation automobile driving module, a brake system executor module, a brake signal acquisition module and a pedal simulator module. An angle of a brake pedal (40) of a pedal simulator in the automobile driving module is changed to output a brake voltage value to control a brake torque motor (12) to vary; the number of balancing weights (27) on a brake disc (18) of the automobile driving module is changed to implement variable rotational inertias of an automobile load; an output of a frequency converter (3) in the automobile driving module is changed to control the rotating speed of a three-phase asynchronous motor (4) to implement a variable automobile speed; and an executor torque motor (12) and a speed reducer (11) of the brake system are changed to change parameters of the executor module to implement variable simulated models. The present testing bench can perform a real simulation on a working process of an automobile electro-mechanical brake system, has a simple structure and low manufacturing cost, can be easily implemented, and can facilitate measurement of a brake force and brake clearance elimination time of the electro-mechanical brake system.
