1、洛阳理工学院毕业设计（论文） I 膜片弹簧离合器毕业设计 摘要 汽车是现代生活中不可或缺的交通工具。汽车 离合器的主要功用是分离发动机传来的动力，以使变速箱顺利挂挡或换挡；柔顺地接合动力，保证车辆平稳起步；超负荷时离合器打滑以保护零件免受损坏。 根据传递动力的方式，离合器分为摩擦式和液力式两种 ,目前摩擦式应用 比较广泛。摩擦式离合器，根据从动盘的数目，可分为单片式、双片式和多片式 3种；根据加压方式，可分为常接合式和非常接合式两种；根据其作用原理，还有单作用式和双作用式之分。 双作用离合器是 汽车及拖拉机的部件之一，它是由 安装在一起的两个不同功能的离合器：即将动力传给驱动轮的主离合器和将动
2、力传给动力输出轴的副离合器。 单片离合器和双片离合器的优缺点对比：单片摩 擦离合器具有从动部分转动惯量小、散热性好、结构简单、调整方便 、尺寸紧凑、分离彻底等优点；而双片和多片式离合器接合虽较平顺，但 分离不彻底、从动部分转动惯量大、中间压盘散热不良，结构复杂、成本高。故双片离合器一般只应用在径向尺寸受限 或 采 用单 片时摩擦转矩不够的场合。 关键词 ： 单片离合器 ，双片离合器 ,摩擦式离合器 ，液力式离合器 变速箱 洛阳理工学院毕业设计（论文） II Diaphragm spring clutch graduation design ABSTRACT Automotive is an i
3、ntegral part of modern life transportation. The main function of tractor clutch is the driving force came from the engine, so that the transmission of gearbox shift smoothly ； flexibility and joint force to ensure a smooth start of vehicles； overloaded when the clutch slipping to protect components
4、from damage. According to convey the driving force, friction clutch is divided into two-and-hydraulic, a comprehensive range of friction applications. Friction clutch, according to the number-driven, can be divided into single-and double-and multi-chip three kinds； under pressure, can be divided int
5、o joint-and often very junction of the two, according to its principle role , Single-and dual-role of the sub-type role. Double-action clutch of motor vehicles and tractors is one of the components, it is installed with a clutch two different functions: to be the main force driving wheel transmissio
6、n clutch and the power transmission power output shaft of the clutch. Single and double-clutch clutch the advantages and disadvantages compared: Friction clutch single moment of inertia has driven some small amount of heat is good, simple structure, the adjustment convenient, compact size, the advan
7、tages of complete separation, while dual-and multi-chip clutch engagement Although more smoothly, Zhang is not completely isolated from the Portion moment of inertia, the middle-pressure cooling bad, structural complexity and high cost. Therefore, double-clutch is generally limited size of the radial or friction torque when using single-chip not enough occasions.
