(毕业设计)微型客车制动系统设计毕业论文 本科生毕业设计（论文） 摘 要 随着我国经济的迅速发展，如何提高运输生产率已成为一个迫在眉睫的问题。但必须以保证行驶的安全为前提，汽车的制动性是一个重要的参数。因此，对汽制动系统的研究、开发是汽车工业重要的课题。如何改善汽车的制动效能、改善制动器的结构是一个重要环节。 本次设计主要是对微型客车系统结构进行分析的基础上，根据对微型客车系统的要求，设计出合理的符合国家标准和行业标准的制动系统。 制动系统设计是根据整车主要参数和相关车型，制定出制动系统的结构方案，设计计算确定前、后盘式制动器、制动主缸的主要尺寸和结构形式。绘制出了前、后制动器装配图、制动主缸装配图、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。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。结果表明设计出的制动系统是合理的、符合国家标准的。 关键词：微型客车；制动；鼓式制动器；制动主缸；液压系统 I 本科生毕业设计（论文） Abstract As Chinese rapid economic development, how to improve transport productivity has become a pressing issue . However, it must be to ensure the safety of travelling on the premise that the brake of the car is an important parameter Therefore, the steam brake system research and development the automotive industry is an important issue. How to improve the car’s braking efficiency, improve the structure of brake is an important link. Based on the structural analysis and the design requirements of mimi passenger car’s braking system, a braking system design is performed in this thesis, according to the national and professional standards. Through analyzing the main parameters of the entire vehicle, the braking system design starts from determination of the structure scheme. Calculating and determining the main dimension and structural type of the front、rear disc brake，brake master cylinder，and therefore draw the engineering drawings of the front and rear brakes, the master brake cylinder, the diagram of the brake pipelines. Furthermore, each target of the designed system is analyzed for checking whether it meets the requirements. some factors are considered in this thesis, such as simple structure, low costs, and environmental protection, etc. The result shows that the design is reasonable and accurate, comparing with the related national standards.
