微型汽车膜片弹簧离合器设计与分析

微型汽车膜片弹簧离合器设计与分析摘要当车子在起动的瞬间，就缓慢的向前行驶，因此人们有了这样的体会：当车子刚挂上一档，左脚就缓慢的提起离合踏板，然后右脚就慢慢踩下加速踏板使发动机供油量逐渐增加，才能让车子缓缓启动。换档操作时，要在快速踩下离合踏板的同时完成换档动作，这样才能有效的减少对齿轮的冲击：如果出现错误了处理方法，或者如果不是因为高速离合的存在，而是直接踩下了刹车踏板，则整个齿轮机构以及发动机都将遭受极大的撞击，这对一辆车的整个使用寿命将产生相当大的危害。因此该文中首次明确了高速离合的基本参数、尺寸以及约束条件。随后，又根据手推式膜片弹簧离合器的特性特点，对摩擦片、膜片弹簧、从动盘总成、离合器盖总成、分离轴承总成及操纵机构等进行了设计计算和校核，设计出了一种能满足小型汽车性能需求的离合器，最后依据所计算的数据画出装配图和重要零件图。关键词：离合器推式膜片弹簧AbstractWhen the car starts at the moment,it drives forward slowly,so people have this experience:when the car just engages a gear,the left foot slowly lifts the clutch pedal,and then the right footslowly presses the accelerator pedal to gradually increase the engine fuel supply,in order to letthe car start slowly.When shifting gears,it is necessary to quickly press the clutch pedal whilecompleting the shifting action,so as to effectively reduce the impact on the gear;If there is awrong way to deal with it,or if the brake pedal is directly pressed if it is not for the presence of ahigh-speed clutch,the entire gear mechanism,as well as the engine,will suffer a great impact,which will cause considerable harm to the entire service life of a car.Therefore,the basicparameters,dimensions and constraints of high-speed clutches are clarified for the first time.Subsequently,according to the characteristics of the walk-behind diaphragm spring clutch,thefriction plate,diaphragm spring,driven disc assembly,clutch cover assembly,release bearingassembly and control mechanism were designed,calculated and checked,and a clutch that couldmeet the performance needs of small cars was designed,and finally assembly drawings andimportant parts drawings were drawn according to the calculated data.Key Words:Clutch push diaphragm spring目录摘要Abstract......第一章绪论1.1研究背景及意义1.2离合器组成及功用.21.3膜片弹簧离合器简介.2第二章离合器结构设计方案..42.1小型汽车基本参数...42.2离合器结构设计概述….42.3离合器主要参数的确定.6第三章膜片弹簧的设计。.103.1膜片弹簧基本参数.103.2膜片弹簧的设计…113.3膜片弹簧的强度校核及优化.15第四章从动盘总成的设计.184.1从动盘的组成形式及要求184.2从动片的设计.。194.3从动盘毅的设计….194.4花键强度的校核194.5扭转减振器的设计.19第五章压盘和离合器盖的设计235.1压盘的设计..235.2离合器盖的设计.24第六章离合器操纵机构的设计.256.1操纵机构的设计….25
