离合器是汽车传动系中直接与发动机相连接的总成,其主要功用是切断和实现对传动系的动力传递,保证汽车起步时将发动机与传动系平顺地接合,确保汽车平稳起步;在换挡时将发动机与传动系分离,减少变速器中换挡齿轮之间的冲击;在工作中受到大的动载荷时,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。
首先对轻型货车车离合器的结构型式进行合理选择,主要是对从动盘数及干湿式的选择、压紧弹簧的结构型式及布置和从动盘的结构型式选择,并利用软件绘制轻型货车膜片弹簧离合器装配图;再进行离合器的基本结构尺寸和参数的选择及计算;最后进行离合器零件的结构选型及设计计算,主要是对从动盘总成设计,压盘、传力片的设计校核,膜片弹簧主要参数的选择、设计和强度校核,并绘制离合器零件图。
最后,对离合器进行装配工艺设计分析,并在DELMIA平台上完成装配工艺仿真,验证结构的装配工艺可行性,输出装配动画。

ABSTRACT
Clutch is the assembly which is directly connected with engine in the automobile power train. And its main function is to cut off or implement the power transmission in the power train. It ensured the engine and the power train perfectly smooth join together when the automobile starting up and insure the automobile smooth starting up. The clutch is disconnected the engine and the power train when the automobile stage changeover. It reduced the impact between the shift gears of the transmission. When the transmission worked by the great dynamic load, the clutch can limit the breakdown torque of the power train, to prevent the accessory of the power train damage due to overload. It effectively reduced the vibration and noise of the power train.
First, the structure of light goods vehicles clutch type for a reasonable choice is driven mainly dry and wet plate number and choice pression spring structure type and layout and structure of the driven plate type choice and use of software to draw a light goods vehicle diaphragm spring clutch assembly drawing; further the basic structure of clutch size and parameter selection and calculation; Finally, the structure of the clutch parts selection and design calculations, the main design is driven disc assembly, pressure plate, transfer film design verification, the main parameters of the diaphragm spring Selection, design and strength check, and the mapping of the clutch parts diagram.
Finally, the clutch assembly process design and analysis, and DELMIA simulation platform plete assembly
