Abstract

The invention provides a brake testing device, and the device comprises a testing platform; a first installation support, wherein a to-be-tested braking clamp is installed on the first installation support; a second installation support, wherein a brake disc cooperating with the braking clamp is hinged to the second installation support; a driving apparatus which is connected with the brake disc, and drives the brake disc to rotate; a pressurizing apparatus; a muddy water storage unit which is connected with a valve control apparatus, wherein the muddy water storage unit and the valve control apparatus are fixed on a third installation support, and the third installation support is hinged to the second installation support; and a central control board which is in control connection with the pressurizing apparatus, the driving apparatus and the valve control apparatus. The device is simple in structure, is convenient to manufacture, and is high in practicality. The device can effectively facilitate the checking of the cause to the wear aggravation or eccentric wear of a friction plate of a brake because of muddy water, and also can provide testing support for the sealing performance evaluation of a brake positioning pin, a guide pin and a piston dustproof cover.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a brake test device. Background technique [0002] During the road test of the car, when the car passes through the mud puddle, the mud water will splash on the brake. The inner side of the dust cover, which increases the sliding resistance of the guide pins, positioning pins, and pistons; when the brake pedal is stepped on, the wear of the friction plates on both sides of the brake may be inconsistent. After that, it will cause increased wear or eccentric wear of the friction plates on both sides of the brake, which will affect the performance and service life of the entire brake. [0003] At present, there is no mature test device that can be used for test simulation and analysis of such problems. Contents of the invention [0004] In order to overcome the technical problem in the prior art that muddy water causes aggravated wear or eccentric wear of the br...
