Vehicle ABS brake test bench capable of carrying out multiple tests

Abstract

The invention provides a vehicle ABS brake test bench capable of carrying out multiple tests. According to the test bench, the front left and front right ends and the back left and back right ends of a rack platform is equipped with individual wheel speed detection devices at and wheel ABS simulator fixing device, and the brake performance of a whole vehicle ABS or wheel ABS braking simulation device can be detected. A test bench roller group controls the differences between two shafts of different vehicle models through an electric telescopic rod, two ends of the electric telescopic rod are dynamically connected to two shafts of the roller group, the diameters of wheels of different sizes can be accurately controlled, and the purpose of an accurate test is achieved. According to the vehicle ABS brake test bench, the brake effect of the whole vehicle or a single tyre under the effect of an ABS in multiple conditions can be accurately detected, and the vehicle ABS brake test bench has significant scientific research value and teaching value and has the advantages of simple structure and convenient operation.

Description

technical field [0001] The invention relates to the field of automobile detection, in particular to a vehicle ABS braking test bench capable of performing various tests. Background technique [0002] Since ABS can significantly improve the braking performance of automobiles, it has become the basic equipment of automobile braking systems. With the increasing application of ABS in automobiles, how to accurately, quickly and effectively detect the working performance of ABS has become a very urgent task. task. At present, the method widely used at home and abroad to test the working performance of automotive ABS is the actual road test, but from the test situation, this method has defects such as high cost, long cycle, and low accuracy. [0003] Now there are some ABS test equipment using common inertial brake test benches, which can only measure a certain type of vehicle with a fixed wheelbase, and cannot measure a single wheel simulation device in the experimental research ...

AI Technical Summary

Problems solved by technology

Especially in the environment of testing and teaching, it is more conducive to the detection of ABS performance if the vehicle and wheel ABS braking simulators are tested separately, but the existing technology does not have the detection function under the above conditions, and cannot be used for different Effective detection of ABS performance of vehicles with wheelbase and different wheel diameters cannot achieve the proper detection and evaluation function
