Abstract
As the most important kind of vehicles, automobile now plays an irreplaceable role in modern society. While choosing the car, people will focus more on security rather than appearance and comfort. In fact, the vehicle braking system on the safety play a vital role.In recent years, with advances in vehicle technology and the improvement of vehicle speed, which was becoming increasingly obvious importance. A large number of automotive engineers in improving the performance of automobile brake study a great deal of effort into the reseach. At present, research on the automobile brake mainly concentrated in the brake control, brake control, including the theory and methods, and the introduction of new technologies. In China, automobile mostly use servo breaking system with vacuum booster, therefore, its indicators have been taken seriously. This paper introduces the work principle and indicators of the vacuum booster, particularly on Self-priming & space travel by analyzing their causes and effects. And we puts forward a set of mature design after referring to the test method of Self-priming & space travel in the world. Then we design a fixture, with the right grating, cylinder and motor chosen, at last build up a complete test bench through electrical testing. In addition, the paper discusses the Collection methods against measurements of Self-priming & space travel, and chooses the relative better one. At the end of this paper, some proposals have been advanced in protecting the Aesthetics of valuable components and bench during the specification debugging; Also, a few plans of improvement in test method are brought forward. The paper contains detailed description of design of the structure of test, assembly drawings, spare parts map of the bench.
