santana2000轿车制动系统的设计毕业设计摘 要 国内汽车市场迅速发展，而轿车是汽车发展的方向。然而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。 本说明书主要介绍了santana2000轿车制动系统的设计。首先介绍了汽车制动系统的发展、结构、分类，并通过对鼓式制动器和盘式制动器的结构及优缺点进行分析。最终确定方案采用液压双回路前盘后鼓式制动器。除此之外，它还介绍了前后制动器、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等的设计过程。 关键字：制动；鼓式制动器；盘式制动器；液压 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 of the santana2000 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 drum.
