4座微型客货两用车设计（离合器及操纵机构设计）
摘 要
离合器是直接连接发动机和传动系统中的总成之一.他主要包含主动部分,从动部分,压紧机构和操纵机构等四部分.
主动部分,从动部分和压紧机构是保证离合器处于接合状态并能传递动力的基本结构.操作机构是使离合器分离的机构.正是这四部分机构之间相互协调配合,已达到汽车起步时将发动机与传动系平顺地接合,换档式将发动机与传动系分离,减少变速箱内齿轮的冲击.
本次设计主要对4微型座客货两用车的离合器进行设计。首先对离合器进行了结构上的设计，此离合器选用的是膜片弹簧推式离合器。结构和方式选定后对此方案进行了计算，主要计算内容如下：
摩擦片主要参数的选择
膜片弹簧主要参数的选择
摩擦片基本参数的优化
扭转减振器设计
离合器踏板行程及踏板力的计算
从动盘总成的设计计算与参数选择
关键词：离合器，摩擦片，膜片弹簧，操纵机构
4 MICRO- DUAL-USE CAR DESIGN (CLUTCH AND THE MANIPULATION OF BODY DESIGN)
ABSTRACT
Clutch is directly connected to the engine and transmission system in one of the assembly. He mainly includes part of the initiative, part of the driven, pinched agencies and institutions, such as manipulation of four parts.
Part of the initiative, pinched and driven some institutions in the clutch engagement is to ensure that state power and to convey the basic structure. Clutch operation is to separate bodies of the institutions. It is precisely this four-part mutual coordination and cooperation between agencies, have reached the car at the start Engine and transmission system will smooth the joint, transmission and engine-transmission system will be separated to reduce the impact of gear in the gearbox.
The design of the four major micro-Block dual-use car the clutch design. First a clutch of structural design, this is the choice of clutch diaphragm spring push-type clutch. Structure and approach selected this option were calculated mainly calculated as follows:
Friction main parameters of the choice of films
Diaphragm spring main parameters of choice
The basic parameters of friction-optimized
Reversing the shock absorber design
Clutch pedal and the itinerary of the calculation
Assembly-driven computing and the design parameters
KEY WORD: clutch, friction films, silent spring, the manipulation of body
