ABSTRACT
Automobile brake system function is to reduce the speed of cars to slow down and drive right up to parking,When traveling downhill, so that the stability of vehicle speed to maintain proper To make reliable cars parked in the ramp or in situ.
The brake performance iS one of the most important safe performances for the automobile.With the increase of running speed of the vehicle;the requirements to the brake performance are getting more and more strict.Besides the good brake performance,the brake system of the automobile is required to reduce the pedal force of the driver.Therefore,the power servo brake system has made a great development in the automobile.
The barometric brake system is the most familiar power servo brake system.The barometric brake system is the first development of a dynamic braking system. Its energy supply all equipment and gear-type pressure Most of the control device is a brake pedal and the brake and other institutions formed the original, Also some in the brake pedal between institutions and also in series with hydraulic control gear. In this paper, the application of a kind of heavy goods vehicles, Through theoretical analysis and calculation of the structure of its air brake system design.
