机械设计说明书-大众捷达轿车前轮制动器设计

本科毕业设计(论文)题目：大众捷达轿车前轮制动器设计 大众捷达汽车前轮制动器设计摘要近年来我国汽车市场迅速发展，特别是轿车汽车发展的方向。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捷达轿车前轮盘式制动系统的设计。首先介绍了汽车制动系统的发展、结构、分类，并对鼓式制动器和盘式制动器的结构及优缺点进行分析。设计计算确定前盘、后鼓式制动器、制动主缸的主要尺寸和结构形式。绘制出了前制动器装配图，及零件装配图。最终对设计出的制动系统的各项指标进行评价分析。另外在设计的同时考虑了其结构简单、工作可靠、成本低等因素。通过本次设计的计算结果表明设计出的制动系统是合理的、符合标准的。其满足结构简单、成本低、工作可靠等要求。
