Its main task is to pass the role of the frame between the wheels and all the forces and moments; mitigate the impact of the road to pass the frame load bearing vibration attenuation resulting system, ensure the car ride comfort; ensure that the wheels on the road ideal when the load changes and uneven motion characteristics, to ensure the cars handling and stability, so that cars get high speed capability. According to the basic theory of the specification of the vehicle suspension , designed for automotive suspension assembly structure , mainly on the main parameters of a medium goods vehicle leaf spring suspension design calculations, including medium-sized truck leaf spring front axle , rear axle , Vice -style leaf springs , automobile shock absorber select parameters calculations. While the use of solid works to establish a spring three-dimensional model for the stress analysis results meet design requirements. Finally, a more rational design of front and rear suspension structure to provide a more valuable data for further design of a leaf spring suspension . Keywords : Medium truck ; multi-piece leaf spring ; non- independent suspension ; solid works; stress analysis ; Absorber  目 录 摘要 Ⅰ Abstract Ⅱ 第1章 绪论 1 第2章 总体设计 2 2.1轴数、驱动形式、布置形式 2 2.2汽车主要参数设计 2 2.2.1主要尺寸 2 2.2.2进行汽车轴荷分配 2 2.2.3最小转弯直径 2 2.2.4通过性几何参数
