Abstract
The rapid development of the domestic vehicle market, saloon car is an important tendency of vehicle. However, with increasing of vehicle, security issues are arising from increasingly attracting attention, the braking system is one of important system of active safety. Therefore, how to design a high-performance braking system, to provide protection for safe driving is the main problem we must solve. In addition, with increasing competition of vehicle market, how to shorten the product development cycle, to improve design efficiency and to lower costs, to improve the market competitiveness of products, and has become a key to success of enterprises.
This paper mainly introduces the design of braking system. Fist of all, braking system’s development, structure and category are shown. Besides, this paper also introduces the designing process of rear brake, braking cylinder, parameter’s choice of main components braking and channel settings.
Key words: braking; brake drum;
