内容简介：

HKD640微型客车设计（前桥、前悬架与转向系设计）摘 要本次设计中我的设计任务微型客车的前桥、前悬架与转向系设计。由于本车前桥采用了麦弗逊式独立悬架，所以前桥采用与之相配合的断开式车桥，属于转向驱动桥。前悬架有独立悬架与非独立悬架之分，本车前悬架采用了麦弗逊式独立悬架，其优点是增加悬架了两前轮内测的空间，便于发动机和起一些不简单布置。主要对悬架的性能参数进行确定，对弹性元件进行了计算，并选择了合适的减振器。通过对悬架主要参数的设计与计算，从而保证本车的行驶平顺性与减震性能。汽车转向系的设计主要包括了转向前桥设计，转向器选择的是循环球式转向器，并通过计算使之符合设计要求，并对专项题型进行计算，并通过优化使之接近理想状态。为保障整车性能，在设计时尽量对前桥和转向系进行优化。设计中，主要通过查看实际车辆，总结课本知识，翻阅有关汽车方面的文章来研究前桥、前悬架和转向系，并验算了有关零部件的结构强度和刚度。最后进行了设计总结。关键字：微型客车、前悬挂系统、转向系统、转向梯形、 非独立悬架、独立悬架HKD640 minibus design (front axle, front suspension and steering system design)AbstractThe design of the task of designing my first mini-bus bridge, the front suspension and steering design. As the front McPherson independent suspension bridge used, so use with matching front axle disconnect axles, drive axles are turning. Front suspension with independent suspension and divided into non-independent suspension, the car front suspension uses McPherson independent suspension, its advantage is to increase the front suspension of the two closed beta of space, easy starting engine and a number of simple layout. The main performance parameters of the suspension to determine, on the elastic components were calculated, and select the appropriate shock absorber. The main parameters of the suspension through the design and calculation, in order to ensure the vehicle ride comfort and shock absorption properties. Automotive Steering System Design includes the design of steering front axle, steering gear choice is a recirculating ball steering, and through calculation to conform to design requirements, and special Questions in calculation, and by optimizing to near Lixiangzhuangtai. For the protection of vehicle performance, as far as possible in the design of the front axle and steering system optimization. Design, mainly by looking at the actual vehicles, concluded textbook knowledge, read the article in respect of the vehicle to study the front axle, front suspension and steering systems, and checking the relevant parts of the structural strength and rigidity. Finally, the design summary. KEY WORDS: The miniature passenger train, the front hangs system, th
