四驱汽车离合器的设计.docVIP

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。 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。 本文主要是对狮跑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：利用Pro/E、CAD等计算机辅助设计软件进行相关设计，并用MATLAB软件对膜片弹簧的弹性变形进行了建模。主要进行了以下工作：根据发动机最大转矩，转速，整车质量，车轮半径等设计狮跑汽车离合器的各部件，主要有摩擦片的选择，从动盘总成设计，圆柱螺旋弹簧设计,膜片弹簧设计，压盘设计以及离合器盖的设计。 关键词: 离合器;膜片弹簧;从动盘;压盘;摩擦片 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.
