Abstract

A passenger-vehicle four-end braking system test device is characterized in that a DC (direct current) velocity modulation motor is fixedly arranged on a main bottom plate; an output shaft of the DC velocity modulation motor is connected with an inertial flywheel taper shaft through a coupling; the output end of the flywheel taper-shaft is connected with an input shaft of an intermediate axle through a coupling; the output end of the intermediate axle is connected with an input shaft of a rear axle through a transmission shaft; a drum brake clamp is respectively arranged on hub ends of the intermediate axle and the rear axle; a drum brake of a drum-style brake is mounted on the drum brake clamp and a brake shoe matched with the drum-style brake is arranged on a brake shoe clamp; and the brake shoe clamp is connected with a torque sensor through a mounting shaft. The invention adopts the motor to drive the flywheel to rotate and the flywheel can idle without power after the preset rotation speed is reached; and the braking to the whole test device can be realized by four-end brakes, the braking process of vehicles can be effectively simulated, and the four-ends brakes can be tested simultaneously in the braking process so as to provide evidence for both the performance test of the braking system and the research of the braking process.

Description

technical field [0001] The invention belongs to automobile bench test equipment, more specifically, it is a braking simulation test device for simultaneously performing braking detection on four brakes in the detection test of the automobile braking system. Background technique [0002] The braking system is an important part of the car, and its performance directly affects the safety performance of the car. It is one of the important contents of automobile performance testing to carry out relevant tests on the braking process and to test its braking performance. [0003] At present, the inertial test bench for performance testing of brakes is relatively mature, and can test the braking performance, thermal fading resistance, and fatigue life of brakes. However, the common ones are basically testing equipment for single-ended or double-ended brakes, and for simultaneous testing of four-ended brakes, there is no corresponding bench test equipment except for vehicle testing. ...
