随着汽车运输的发展，汽车性能趋于高速化，载货汽车趋于大型化，要求发动机的功率和转速不断地提高，使离合器的使用条件也日渐恶化。因此，增加离合器传递转矩的能力，提高其使用可靠性及寿命，简化操作(在某些车型上以至向自动操纵发展)，已成为当代汽车离合器的发展趋势。
离合器是汽车传动系中的重要部件，它的构造特性与发展和传动系紧密相关，本文针沃尔沃汽车的各项参数，设计推式膜片弹簧离合器。
离合器设计的内容主要包括压盘总成、从动盘总成、膜片弹簧三个部分。首先，对离合器各零件的参数、尺寸、材料、及结构进行设计，然后用Auto CAD工程图。
本文还重点研究了膜片弹簧在分离过程中的受力，对受力过程进行数学分析，并对其进行校核，以提高膜片弹簧离合器的使用寿命，使膜片弹簧离合器在工作过程中处于最佳状态。

ABSTRACT
 
The clutch is an important part of the automobile power train, its characteristic and development have close relation with the power train. Based on Beijing qienuoji’s parameter, this paper aim to design pushing type diaphragm-spring clutch.
There are three main parts of the clutch design: driven disc design, diaphragm-spring design and the driving disc design. Firstly, this paper calculates the parameters, and chooses sizes and materials for the clutch’s parts. Then draw the three-dimension-blueprint of the assembly and components. Finally transforms the three-dimension-blueprint into Auto CAD engineering plat.
Along with the development of automobile transportation, car performance, auto high-speed tends to request the engine tends to large-scale, power and speed continuously improve the conditions of use, make clutch is worsening. Therefore, to increase the ability of transmission torque clutch, improve its use, simplify the operation reliability and life (in some models and automatic controlling to develop), has become the development trend of modern automobile clutch.
This paper also studies force exerted on diaphragm in the process of separation, and analyzing the process mathematically, then examines and calculates relative parameter. In conclusion, the design will prolong the lifetime of diaphragm-spring clutch, and makes the clutch in best state when it’s working.
