摘　要
离合器在机械传动系中作为一个独立的总成而存在，它是汽车传动系中直接与发动机相连接的总成，离合器在传递发动机力矩时起着至关重要的作用，本次设计抛弃传统推式膜片弹簧离合器，设计拉式膜片弹簧离合器，首先考虑各种因素对各个零部件进行选材选择尺寸。然后进行离合器的结构设计，最后对一些常用零部件进行优化和校核，主要优化的零部件有摩擦片、膜片弹簧、减震弹簧、从动盘毂等等。
本设计分析了本设计所要采用的的膜片弹簧离合器，对膜片弹簧离合器进行了分类，阐述了膜片弹簧离合器的原理和组成，及其特性。通过详细的推导过程积累了大量的数据，并成功的绘制出了膜片弹簧离合器的成品图。在计算中，首先确定摩擦片外径尺寸，然后根据该尺寸对其他部件总成进行了计算和设计。通过计算校核摩擦片外径尺寸，计算选择出其他部件的外形尺寸，再对其进行校核，确定是否能达到设计要求。设计包括对从动盘总成的设计校核，对压盘的设计校核，对离合器盖的设计校核及离合器盖的设计校核和优化。具体设计计算了摩擦片、扭转减振器、膜片弹簧、压盘、离合器盖、传动片等多个部件总成

Abstract
In the mechanical clutch transmission lines as an independent assembly and the existence, it is the automotive power train and engine directly connected to the assembly, the clutch in the transmission of engine torque when it plays a vital role in this design to abandon the traditional push -Clutch diaphragm spring, pull-designed clutch diaphragm spring, first of all to consider the various factors on the choice of material for various parts size. And then proceed to the structural design of the clutch, the last of a number of common parts and optimize verification, and optimization of the main parts of the film there is friction, diaphragm spring, spring damping, wheel driven disk, and so on, and some of the key components to this article a certain amount of analysis.
Analysis of the design the diaphragm spring clutch to be used in this design,the diaphragm spring clutch is classified,and expounds the principle and composition of the diaphragm spring clutch, and its characteristics. Through the detailed derivation of the accumulation of a large number of data, and successfully mapped the diaphragm spring clutch refined graph. In the calculation, first determine the friction plate diameter size, then the size of the other components assembly were calculated and designed according to. Through the calculation of the friction plate diameter size, calculated choice of dimensions of other parts, then carries on the check, to determine whether can meet the design requirements. The design includes the design of check of the driven disc assembly, design check of the pressure plate, the design verification and optimization　design verification and clutch clutch cover cover. The friction plate, torsional damper, diaphragm spring, pressure plate, clutch cover, transmission and a plurality of parts assembly of the calculation of the specific design.
