Device and method for detecting brake performance of automobile

Abstract

The invention discloses a device and method for detecting brake performance of an automobile. The device comprises an inertia mechanism, a driving mechanism, a first rolling mechanism, a first revolving speed detecting unit and a second revolving speed detecting unit, wherein the driving mechanism drives the inertia mechanism to rotate, the first rolling mechanism is contacted with car wheels in a friction mode, the first rolling mechanism is connected with the inertia mechanism through a first synchronous transmission mechanism, the first revolving speed detecting unit is used for detecting the revolving speed of the first rolling mechanism, and the second revolving speed detecting unit is used for detecting the revolving speed of the car wheels. The device and the method for detecting the brake performance of the automobile can simulate braking force of the road surface on the automobile, obtains brake performance parameters of the automobile through a bench test and improves the precision of a simulating test of driving of the automobile on the road surface. The device can be used for conducting a brake performance study on a single wheel and the whole automobile, and also can be used for conducting a testing study on the dynamic quality and driving stability of the automobile. The device for detecting the brake performance of the automobile has the advantages of being low in cost, easy to produce, capable of being conveniently used by a laboratory, and beneficial to operation of operating personnel.

Description

technical field [0001] The invention belongs to the technical field of automobile safety situations, and in particular relates to a device and method for detecting automobile braking performance. Background technique [0002] At present, there are mainly two types of automotive ABS performance testing and testing: road test and bench test. Road tests are widely used in automotive ABS performance testing and testing. However, the current road test equipment is expensive, the parameter acquisition process is complicated, and the equipment installation and positioning requirements are high. It is difficult for ordinary scientific research units to conduct independent tests. For the detection and test of automobile ABS performance, a device with simple equipment, convenient installation, high detection accuracy, low cost, and accurate and timely analysis is required to complete. [0003] After the car brakes rapidly at high speed, the tires will often slip on the road. In the c...

Problems solved by technology

At present, there are still unformed automobile ABS performance testing and evaluation equipment, which are mainly tested by road tests, but road tests are dangerous and require a lot of time and money, especially in the development of ABS and the testing of products after crashes. The process is extremely limited

Although the cost of the bench test is low and the construction period is short, it is impossible to obtain the real state of the automobile ABS when it is working, the accuracy of the bench test is low, and the dynamic performance, working process and fault parameters of the ABS are not easy to obtain
