Ramp ABS (Anti-lock Brake System) braking test bench

Abstract

The invention discloses a ramp ABS (Anti-lock Brake System) braking test bench. The test bench comprises a front left wheel ABS braking device assembly, a front right wheel ABS braking device assembly, a rear right wheel ABS braking device assembly, a rear left wheel ABS braking device assembly, a roller set rack cap, a roller set rack, a lifting hydraulic cylinder, a rack supporting base, a rack lifting push rod and a platform, wherein the front left wheel ABS braking device assembly, the front right wheel ABS braking device assembly, the rear right wheel ABS braking device assembly and the rear left wheel ABS braking device assembly are the same in structure, and are symmetrically mounted at the four corners of the roller set rack by taking the axle of the roller set rack as a symmetric center. The ramp ABS braking test bench can accurately detect the braking effects of vehicle ABSs on ramps under various situations and has obvious values in scientific research and teaching. Furthermore, the ramp ABS braking test bench has the advantages of simple structure and convenience in operation.

Description

technical field [0001] The invention relates to the field of automobile detection, in particular to a test bench for detecting the ABS braking efficiency of a vehicle on a slope. Background technique [0002] In the field of automobile testing, road testing is mostly used for testing the ABS braking performance of foreign vehicles. This method has problems such as high cost, long cycle, and low precision. There are also some ABS testing equipment in our country that use ordinary flat brake test benches or inertial roller test benches. But these kinds of test benches can only detect vehicle ABS brakes on flat roads. And when the vehicle is driving on roads such as hilly areas and winding mountain roads, that is, the performance of the ABS when the vehicle is braking on an uphill slope, a downhill slope, or a slope turning, remains to be tested. According to the current road conditions in our country, the slope angle that ordinary vehicles can drive on is about 0-30°. Differ...
