摘 要

汽车离合器位于发动机和变速箱之间的飞轮壳内,用螺钉将离合器总成固定在飞轮的后平面上,离合器的输出轴就是变速箱的输入轴。在汽车行驶过程中,驾驶员可根据需要踩下或松开离合器踏板,使发动机与变速箱暂时分离和逐渐接合,以切断或传递发动机向变速器输入的动力。其功用为:(1)使汽车平稳起步;(2)中断给传动系的动力,配合换档;(3)防止传动系过载。

膜片弹簧离合器是近年来在轿车和轻型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轻型汽车膜片弹簧离合器的结构形式,参数选择以及计算过程。

本文主要是对载重2吨轻型汽车的膜片式弹簧离合器进行设计。根据车辆使用条件和车辆参数,按照离合器系统的设计步骤和要求,主要进行了以下工作:选择相关设计参数主要为: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。并进行了总成设计主要为:分离装置的设计,以及从动盘设计(从动盘毂的设计)和圆柱螺旋弹簧设计等。

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 the process of moving vehicle, the driver may need Pedal or release the clutch pedal so that the engine and gearbox temporary separation and progressive joint, to cut off the engine or transmission to the transmission input power. Its function as: (1) the car a smooth start, (2) to interrupt the transmission of power to meet the shift, (3) to prevent transmission of the overload.

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 paper is the single-car theca spring clutch design. According to traffic conditions and vehicle parameters, in accordance with the clutch system of steps and requirements, mainly for the following work:Select the design for the main parameters: the determination of friction-diameter, the determining factor clutch reserve, the pressure on the units identified . And the design of the main assembly: the separation device design, set design and follower (the hub-driven design) and cylindrical coil spring design,and so on.

Keyword: clutch , theca spring,  driven plate , friction disc
