摘 要 悬架是现代汽车上的重要总成之一，它最主要的功能是传递作用在车轮和车架(或车身)之间的一切力和力矩，并缓和汽车驶过不平路面时所产生的冲击，衰减由此引起的承载系统的振动，以保证汽车的行驶平顺性。为了迅速衰减不必要的振动，悬架中还必须包括阻尼元件，即减振器。此外，悬架中确保车轮与车架或车身之间所有力和力矩可靠传递并决定车轮相对于车架或车身的位移特性的连接装置统称为导向机构。 此次设计是对哈飞路宝7110前独立悬架设计 关键词：麦弗逊独立悬架；导向机构；减震器；弹簧；横向稳定器 ABSTRACT Suspension is the modern car on the important assembly, which has one of the main function is to transfer function in the wheels and frame (or body) all between the force and moment, and ease when rough road surface cars driving by the impact of attenuation arising from the vibration of the bearing system, to ensure the smooth running of the car. So must the wheel and frame or body to provide flexible connection between, rely on the elastic element to deliver the wheel or axle and frame or between vertical load of the body, and depend on the deformation to absorb energy, to achieve the purpose of the buffer. This design is to LuBao hafei before 7110 independent suspension design, the graduation design requirements according to a car to retrofit of the entrant 。The overall design of request, to the front suspension design calculation. In order to this suspension design process, the specification separately from the design calculation, the simulation analysis, optimization design with wheat for supporters of suspension design process were introduced in this article. The first elaborated the suspension of the key parts such as: spiral spring, horizontal WenDingGan, shock absorber of such as design, selection and check Keywords: paper independent suspension; Steering mechanism; Shock absorber; Spring;Transverse stabilizer 目 录 摘要 Ⅰ Abstract Ⅱ 第1章 绪论 1 1.1 悬架的功用 1 1.2 悬架的组成 1 1.3 悬架的分类 2 1.3.1 独立悬架 2 1.3.2 麦弗逊悬架 4 1.3.3 非独立悬架 4 1.4 悬架的国内外发展情况 5 第2章 悬架分析设计 7 2.1 悬架结构方案分析 7 2.1.1 独立悬架与独立悬架结构形式的选择 7 2.1.2 悬架具体结构形式的选择 7 2.2 弹性元件 7 2.3 减震元件 7 2.4 传力构件及导向机构 8 2.5 横向稳定器 8 第3章 悬架主要参数的确实 10 3.1 悬架的空间几何参数 11 3.2 悬架的弹性特性和工作行程 11 3.2.1 悬架频率的选择 11 3.2.2 悬架的工作行程 11 3.2.3 悬架刚度的计算 12 第4章 悬架主要零部件的设计 13 4.1 螺旋弹簧的设计计算 13 4.1.1 螺旋弹簧的刚度 13
