摘    要
离合器是客车传动系中直接与发动机相连接的总成，其功用是切断和实现对传动系统的动力传递，以保证客车起步时将发动机与传动系平顺地接合，确保客车平稳起步；在换档时将发动机与传动系分离，减少变速器中换档齿轮之间的冲击；在工作中受到最大的动载荷时，能限制传动系所承受的最大转矩，防止传动系各零件因过载而损坏；有效地降低传动系中的振动和噪声。在现代客车设计中，膜片弹簧式离合器应用越来越广泛。
本设计采用系统化设计方法讨论膜片弹簧式离合器设计，并根据离合器的功能和结构，把离合器分为主动部分、从动部分、分离机构和操纵机构等部分。根据其实际运用要求，设计中详细介绍离合器功能和工作原理，阐明了设计目的，分析了膜片弹簧及离合器从动盘特点，并对离合器主要部分:摩擦片、压盘、膜片弹簧等进行了计算。

Clutch assembly design of bus and coach

Abstract
The clutch is the assembly, which directly connect the engine and the transmission. Its function is a cutting and realization in the power deliver of transmission, connecting the engine and the transmission are kept smoothly while the bus and coach is going to start, in order to insure the steady start of vehicle; While shifting gear, it separates the clutch and the gearbox, reduces the impact of shift gear between gears in the gearbox; While being dynamic load up to the maximum in the operate, it can limit the breakdown torque, pull out torque that the transmission depart bear, keep each parts of transmission from damage because of the overload; Reduce vibrate and noise within the transmission availably. Diaphragm clutch is used widely in modern vehicle.
The design uses a systematic design method to discuss the design of diaphragm spring clutch, and in accordance with the functions and structure of the clutch, divided into active part of the clutch, the driven part of the separation and manipulation of body parts. Practical application in accordance with its requirements, clutch design in detail the functions and working principle, designed to set out, analysis of the diaphragm spring and clutch plate follower characteristics, clutch and main parts: friction plate, pressure plate gap, such as diaphragm spring calculated. Clutch and main parts: friction plate, pressure plate gap, such as diaphragm spring calculated.

Key words: Clutch; Driven in part ; Diaphragm Spring; Development; Design
