 摘   要
 
 离合器装在发动机与变速器之间，汽车从启动到行驶的整个过程中，经常需要使用离合器。它的作用是使发动机与变速器之间能逐渐接合，从而保证汽车平稳起步；暂时切断发动机与变速器之间的联系，以便于换档和减少换档时的冲击；当汽车紧急制动时能起分离作用，防止变速器等传动系统过载，起到一定的保护作用。其功用为：（1）使汽车平稳起步；（2）中断给传动系的动力，配合换档；（3）防止传动系过载。
 膜片弹簧离合器是近年来在轿车和轻型汽车上广泛采用的一种离合器，它的转矩容量大而且较稳定，操作轻便，平衡性好，也能大量生产，对于它的研究已经变得越来越重要。
 本设计主要是根据车辆使用条件和车辆的参数，按照离合器系统的设计步骤和要求进行设计。

 ABSTRACT
 
 The coupling installs between the engine and the transmission gearbox, the automobile from the start to the travel entire process, needs to use the coupling frequently. Its function is causes between the engine and the transmission gearbox can join gradually, thus guaranteed that the automobile starts steadily; Shuts off between the engine and transmission gearbox's relation temporarily, is advantageous shifts gears and reduces shifts gears the time impact; When automobile emergency brake can play the separation role, prevents transmission systems and so on transmission gearbox to overload, plays certain protective function. Its function as: (1) the car a smooth start, (2) to interrupt the transmission of power to meet the shift, (3) to prevent transmission of the overload.
 In  recent years theca spring clutch is a kind of clutch that widely Adopted in vehicle and light vehicle . It has great capacity of  torque And more stabley ,manipulate easy and convenient ,well equilibrium ,And also can produce batch .so the research of the clutch is more and more important .
 The design is based mainly on the conditions of vehicles and vehicle parameters, in accordance with the design of the clutch system design steps and requirements.
