毕业设计（论文）-本田思域轿车离合器设计.doc

摘要
对于以内燃机为动力的汽车,离合器在机械传动系中是作为一个独立的总成而存在的,它是汽车传动系中直接与发动机相连接的总成。目前,各种汽车广泛采用的离合器是干式盘形摩擦离合器,是一种依靠主、从动部分之间的摩擦来传递动力且能分离的装置。它主要包括主动部分、从动部分、压紧机构和操纵机构等四大部分。
其离合器是汽车传动系统中直接与发动机相连的部件其作用是在换挡时使发动机和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,并且还可以防止传动系过载。
本文是对本田思域轿车设计离合器,根据车型和配置,选用摩擦式膜片弹簧离合器。通过对车辆各参数的分析和传动系需要,先确定离合器的基本结构和参数,如摩擦片的尺寸和结构形式。再根据所得的参数设计计算从动盘毂、膜片弹簧的结构和尺寸,并对其结构和强度等进行校核。在设计压盘和离合器盖等部件时,需要考虑散热等问题,即要加工散热孔槽。而离合器操纵机构的设计相对简单,即分离轴承和拨叉等部件的设计。最后再对离合器的参数进行优化,使设计出的离合器能更好的与所选车型相匹配,从而达到使传动系的传递效率更高、换挡更顺畅的目的。本文还叙述了离合器各组成部件的材料及加工工艺等。

Abstract
With bustion engine-powered vehicle mechanical transmission systems, the clutch assembly as an independent existence, it is a car transmission lines directly connected with the engine assembly. Widely used for all types of motor vehicle friction clutch, in fact is a kind of rely on their owners, some friction between the follower to pass power cut can be separated institutions. It includes active part of the driven part, pressed bodies, control agencies, in four parts.
Automotive transmission clutch directly connected with the ponents, and its role in the shift when the temporary separation of the engine and gearbox and gradually bonding, to cut off or pass the engine to the transmission input power, and also can prevent transmission line overload.
This article is designed for Honda Civic sedans clutch, depending on model and configuration, use friction-type diaphragm spring clutch. The parameters of the vehicle through the analysis and transmission system needs, first determine the basic structure and parameters of the clutch, such as the friction plate of the size and structure. Then according to the parameters derived from design calculations driven plate hub, the structure and size of diaphragm spring, and its structure and strength to checking. In the design pressure plate and clutch cover and other parts, we need to consider issues such as heat, that is, to processing of cooling holes in tank. The design of the clutch control
