The Bench Test Of Automobile Brake And The Function Analysis Of Friction Material

The brake is the critical part on the automobile, its function is one of the important factors that affect the car safety. The friction material in brake is the most critical component to affect the function of braking. It is a topic to be solved urgently on how to analyze and assure the function of brake through the bench test, thus assure effectively the function and quality of the brake.This paper describes the working principle of the bench test of the automobile brake and explains gist and method of the bench test. The bench test of the automobile brake, by simulating the braking process of the automobile, test brake assembly's function, heat stability, friction slice's wear and strength and so on through testing the automobile brake assembly. In the paper with some car type as the example puts forward the bench test's method and procedure, combines the chart that drew with the collected data through the bench test, and analyses the functions of the friction slice.This paper recounts briefly the structure of drum brake and the advantages of disc brake comparing with the drum brake, requirements of the friction coefficient, rigidity, strength to glue, rate of thermal expansion, elasticity modular etc and the difference of friction material function in china and abroad. According to requirements of the automobile brake to the function of friction material, the paper puts forward the principle to optimize the friction slice from three aspects: the analysis of the test data, the kinds of friction material and the function of friction material.This paper also expatiates on the requirements of that the automobile on the braking function and a few factors affecting the braking function, puts forward the function requirements on brake, analyzes the braking function of brake, and recounts briefly the present condition and the future development trend of the...
