ABSTRACT

Automobile Clutch in the engine and gearbox between the flywheel shell, with screw will be fixed in the clutch assembly after the plane of the flywheel, clutch gearbox output shaft is the input shaft。

In recent years theca spring clutch is a kind of clutch that widely Adopted in vehicle and light vehicle.It has great capacity of torque And more stabley ,manipulate easy and convenient ,well equilibrium ,And also can produce batch .so the research of the clutch is more and more important . This design manual elaborated on the construction form,parametre choose and process of calculate of the light vehicle.

This article is Sportage light vehicles Diaphragm spring clutch design. In accordance with the conditions of vehicles and vehicle parameters, in accordance with the clutch system design steps and requirements, mainly for the following work: the use of Pro / E, CAD and other computer-aided design software related to design and use of MATLAB software, the flexibility of the diaphragm spring deformation modeling. Mainly the work of the following: In accordance with the largest engine torque, speed, vehicle quality and design of the wheel radius, such as the Lions ran the auto clutch parts, mainly the choice of friction plate, follower plate assembly design, the design of cylindrical helical spring, designed diaphragm spring, pressure plate design and the design of the clutch cover.

Key Words: Clutch;Theca Spring;Driven Plate;Friction disc
