摘要
离合器是传动系统与发动机相连的重要部件,主要功能就是实现对动力的切断和对动力输出的传递,保证汽车起步时将发动机与传动系统进行平顺接合,保证起步平稳;在换挡时将发动机动力切断,减少变速器中换挡时齿轮冲击;工作时受到大载荷时,限制传动系最大转矩,防止传动系过载产生损坏,降低传动系统噪声。
本次设计主要针对商用车摩擦离合器的设计,此次课题目的了解离合器的设计过程,其次检验成果,为以后工作打下基础。本课题主要工作内容,首先了解离合器的发展及简介,确定离合器的结构,确定从动盘、压紧弹簧、分离杠杆、从动盘、摩擦片、压盘、离合器盖相关类型;其次对离合器核心参数进行计算,确定摩擦片、后备系数、膜片弹簧参数,在对扭转减振器的参数进行计算校核,以及对离合器的操纵系统进行选取确定结构要求。
最后根据计算参数使用CATIA绘制三维模型,再使用CAD绘制零件图,完成说明书编写。

Abstract
Abstract: The clutch is an important component that is connected to the engine. The main function is to achieve the power cutting and transmission of power output. It ensures that the car is smoothly engaged when the car starts, and the initiation is stable; Disconnect, reduce the gear impact of shifting in the transmission; when it is loaded, the maximum torque of the transmission system is limited to prevent the transmission system overload, and reduce the noise of the transmission system.
This design mainly designed for commercial vehicle friction clutches. The topic's understanding of the design process of clutch, followed by the four-year learning results, and lay the foundation for future work. This topic main work content, first understand the development and introduction of the clutch, determine the structure of the clutch, determine the driven disc, the compression spring, the separation lever, the driven disc, friction plate, pressure plate, clutch cover; followed by the clutch core The parameters are calculated, determine the frictional sheet, the backup coefficient, and the diaphragm spring parameters, calculate the diameter of the torsion damper, and select the determination structure requirements for the clutch control system.
Finally, the three-dimensional model is drawn using CATIA according to the calculation parameters, and then use the CAD to draw the part map, and the manual is written.
