轻型轿车悬架系统的设计【摘要】 本次毕业设计的课题是轻型轿车悬架系统的设计。必须满足以下几个要求：可靠，坚固，耐用，使用成本较低，油耗处于国内中低等水平，为当前主流技术水平。所以，悬架的设计宜选用成熟技术，零部件，彻底的贯彻“三化”原则，较为合理的成本控制。 麦弗逊式独立悬架有着结构简单、紧凑、占用空间小等众多优点，在现代轻型汽车中得到了广泛运用。麦弗逊式独立悬架本毕业设计要求根据某车总体方案要求，对其悬架进行设计计算。为了阐述悬架的设计过程，说明书从设计计算对麦式悬架的设计过程进行了介绍。说明书首先阐述了悬架中关键零部件如：螺旋弹簧、减振器等的设计、选型和；进而分析了悬架的结构特点和运动特征，并以此为基础建立了悬架的物理模型。The design of Light passenger vehicle Suspension System Chen xiang (grade06,class01, Heat Energy and Dynamical Engineering, Shaanxi University of Technology，Hanzhong 723000，Shaanxi ,Tutor：shi shao ning) Abstract Time of graduation practice problem is that the light saloon hangs to put up systematic design. As a result, Must satisfy several the following call for: Reliable , sturdy and durable, use cost comparatively low, the low grade is horizontal in oil being consumed being in in the homeland , the technology is horizontal for current main current. The design putting up therefore, hanging ought to select and use the mature technology , component and part , put three into effect completely spending principle , comparatively rational cost controls. Maifuxun style has had structure simple , compact independent dangerous rack , has occupied space waiting for a lot of merit for a short time , in modern light automobile to apply broadly. Because of this , this time, going forward designing that , that vehicle hangs to adopt the dyadic independent dangerous Maifuxun rack , rear overhang puts up adopt the dyadic overall of band spring rear overhang rack. Such designs that the angle still is from comfortable angle from economy being able to make this vehicle regardless of , can reach a comparatively ideal result. Graduation practice requires that comparatively, the vehicle overall plan demands , the design being in progress to whose dangerous rack secretly schemes against according to some. For the design setting forth the dangerous rack, process , specifications introduce that from designing that the process calculating the design to dyadic dangerous wheat
