西 南 交 通 大 学 本科毕业设计 轻型汽车前后独立悬架设计 THE DESIGN OF A LIGHT TRUCKS INDEPENDENT SUSPENSIONS 摘 要 悬架是汽车中的一个重要总成，它把车架与车轮弹性地联系起来，到汽车的多种使用性能。完成汽车的总体设计并选择汽车的主要参数悬架类型及结构特点完成悬架的结构元件螺旋弹簧、减振器、导向机构、横向稳定杆等。防止车身在转弯时发生过大的横向侧倾Suspension is an important assembly part in the vehicle.It used to connect the wheels to the body elasticity,affects a variety of performances of car.Suspension is not only meet the vehicle requirements of comfort, but also meet the requirements of its handling stability.The two aspects are mutually exclusive. This article is designed to design the front and rear suspension of light trucks.First, it designs the scheme of whole car based on the parameters which were already been given,and selects the main parameters of the car,Including the size parameters, quality parameters and main performance parameters.Based on the completion of automotive Design,it analysis the structural characteristics and type of suspensions, choose the types of suspensions for front and rear suspensions.It chooses the McPherson independent suspension for front suspension,and the Oblique single arm for rear suspension.Then on the suspension of the performance parameters of selection, and the complete suspension of the structural elements of the design calculation,including the coil spring, shock absorber, oriented institutions, horizontal stabilizer bar and so on.Helical springs design and calculation, including the stiffness and strength of the check, make the design of the spring biasing to meet the design requirements. For the front and rear suspension matched shock absorber, damper size calculation parameters, and test whether the shock absorber to meet the strength requirements. In order to prevent the body in turn occurs when excessive lateral roll, each match for the front and rear suspension, a roll bar, to increase suspension roll stiffness. key words：Mcpherson suspension Oblique single arm目 录 第1章 绪论 1 1.1 论文的研究目的和意义 1 1.2 国内外研究现状发展趋势 2 1.3 论文的主要研究内
