车辆毕业设计-丰田collora车盘式制动器设计.pdf

摘 要 国内汽车市场迅速发展，随着汽车保有量的增加，带来的安全问题也越来越引起 人们的注意，而制动系统则是汽车主动安全的重要系统之一。因此，如何开发出高性 能的制动系统，为安全行驶提供保障是我们要解决的主要问题。另外，随着汽车市场 竞争的加剧，如何缩短产品开发周期、提高设计效率，降低成本等，提高产品的市场 竞争力，已经成为企业成功的关键。 主要根据已有的丰田COLLORA车辆的数据对制动系统进行设计。首先介绍了汽车 制动系统的结构、分类，并通过对盘式制动器的结构及优缺点进行分析。确定方案采 用液压双回路盘式制动器。进行前后制动器、制动主缸的设计计算，主要部件的参数 选择及制动管路布置形式，确立了COLLORA车制动器比较完整的设计。 关键词：制动器；盘式制动器；COLLORA；活塞；同步系数 ABSTRACT The rapid development of the domestic vehicle market, 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 ,which based on the data of brake system used in callola. 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 drum. 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.
