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. The brake system in vehicle guarantied the safety of driving. Many rules and regulations have been made for the brake system in detail, which is the starting of our design. This paper mainly introduces the design of braking system of the CHERY A3 type of car. Fist of all, braking system’s development, structure and category are shown, and according to the structures, virtues and weakness of drum brake and disc brake, analysis is done. At last, the plan adopting hydroid two-backway brake with front disc and rear disc. Besides, this paper also introduces the designing process of front brake and rear brake, braking cylinder, parameter’s choice of main components braking and channel settings. Key words: braking; brake drum; brake disc; hydroid pressure 目 录 摘 要 I Abstract II 目 录 III 第一章 总 论 1 1.1汽车制动系概述 1 1.2制动系统设计的意义 3 1.3制动系统研究状态 4 1.4本次设计制动系统应达到的目标 4 1.5本次制动系统设计要求 4 第二章 制动系统设计方案论证分析和选择
