However, with increasing of vehicle, security issues are arising from increasingly attracting attention, the braking system isone 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 petition of vehicle market, how to shorten the product development cycle, to improve design efficiency and to lower costs, to improve the petitiveness of products, and has e a key to ess of enterprises. T his paper mainly introduces the design of braking system of the two type classic of car. F istof 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 drum. B esides, this paper also introduces the designing process of front brake and rear brake, braking cylinder, parameter ’s choice of ponents braking and channel settings. Key words : braking; disc; hydroid pressure 充值下载即送 CAD 图纸, QQ 36396305 III 目录摘要.......................................................................................................................
