dd1062中型客车制动系统改进设计方案说明书学位论文.doc

本科生毕业设计（论文） PAGE  PAGE 40 摘 要 本次设计主要是对中型客车制动系统结构进行分析的基础上，根据对中型客车制动系统的要求，设计出合理的符合国家标准和行业标准的制动系统。汽车制动系统是汽车最重要的系统之一，它直接关系到汽车行驶的安全性。为了保证汽车行驶的安全，制动器性能的好坏成为汽车构造中的重中之重。同时，良好的制动系统还能提高汽车的方向稳定性和制动效能。 首先制定出制动系统的结构方案设计计算确定前盘、后鼓式制动器。绘制出了前、后制动器装配图、制动阀装配图、制动管路布置图。最终对设计出的制动系统的各项指标进行评价分析。 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。 关键词：中型客车；制动系统设计；盘式制动器；鼓式制动器；气压系统； Abstract Based on the structural analysis and the design requirements of n.medium bus braking system, a braking system design is performed in this thesis, according to the national and professional standards. Automotive vehicle braking system is one of the most important system, it is directly related to car driving safety. In order to ensure the safety of automobile travel, automobile brake performance is good or bad to become a top priority in construction. At the same time, good braking system can improve the cars directional stability and braking performance. The braking system design starts from determination of the structure scheme. Calculating and determining the main dimension and structural type of the front disc、drum brake，brake master cylinder，and therefore draw the engineering drawings of the front and rear brakes, Brake valve, the diagram of the brake pipelines. The results show the design of braking system is reasonable, consistent with the standards and satisfies the requests such as simple structure and low cost. Key words: Medium-sized passenger car; braking system design; disc brake; drum brake; pneumatic system; 目录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc296326690 摘 要  PAGEREF _Toc296326690 \h I  HYPERLINK \l _Toc296326691 Abstract  PAGEREF _Toc296326691 \h II  HYPERLINK \l _Toc296326692 第1章 绪 论  PAGEREF _Toc296326692 \h 1  HYPERLINK \l _Toc296326693 1.1 制动器设计的意义及目的  PAGEREF _Toc296326693 \h 1  HYPERLINK \l _Toc296326694 1.2 汽车制动系统设计的要求  PAGEREF _Toc296326694 \h 1  HYPERLINK \l
