摘要
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。
本文基于重型载货汽车的设计要求和设计参数,确定了以拉式膜片弹簧离合器作为设计目标。膜片弹簧离合器是近年来在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。此设计说明书详细的说明了重型载货汽车膜片弹簧离合器的结构形式,参数选择以及计算过程。
本次设计根据车型的类别、使用要求、制造条件以及“三化”(即系列化、通用化、标准化)要求等,选择了结构方案及有关参数,进行了总成设计,并对其一些零件进行了校核:包括摩擦片外径的确定,离合器后备系数的确定,单位压力的确定,从动盘设计,压盘设计,膜片弹簧设计等,为以后从事汽车技术工作打下良好的基础。不仅如此,本次设计借鉴了相关的资料,采用了相关的标准,充分吸收了前人宝贵的经验。

Abstract
Clutch is the assembly which is directly connected with engine in the automobile power train. And its main function is to cut off and implement the transmission of power in the power train. It ensures the engine and the power train perfectly smooth join together when the automobile is starting up and insures the automobile started up smooth. The clutch disconnects the engine and the power train when the automobile stage change over. It reduces the impact between the shift gears of the transmission. When the transmission worked on the great dynamic load, the clutch can limit the breakdown torque of the power train in order to prevent the accessory of the power train that is damaged due to overload. It also can effectively reduce the vibration and noise of the power train.
This article is based on the design requirements and the design parameters of the light truck, it is identified with the pull-type diaphragm spring clutch as the design goal. In recent years, diaphragm spring clutch is a kind of clutch that was widely adopted in saloon cars and light vehicles. It has great capacity of torque and more stable. Meanwhile it manipulate conveniently and has good balance. And It also has high output. So the research of the clutch is e more and more important. This design manual elaborated on the construction form, the para
