潍坊学院本科毕业设计1摘要汽车是现代生活中不可或缺的交通工具。近年来汽车设计和制造技术的进步有目共睹。为了进一步提高产品性能,延长使用寿命,普通机械式离合器技术同样也产生了令人注目的变化。无论从结构特性、产品工艺性能,还是控制技术方面,机械离合器的技术进步从某种程度上反映了设计观念的发展,以及将来可能的技术走势。离合器是汽车传动系中的重要部件，它的构造特性与发展和传动系紧密相关，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。离合器设计的内容主要包括压盘总成、从动盘总成、膜片弹簧三个部分。首先，对离合器各零件的参数、尺寸、材料、及结构进行设计，然后使用Pro/E软件画出推式膜片弹簧的装配及零件的三维图形。最后进行机构运动仿真。本次的设计对原有离合器的设计提出优化和修改的建议，对其以后的设计过程起参考作用。本文还重点研究了膜片弹簧在分离过程中的受力，对受力过程进行数学分析，并对其进行校核，以提高膜片弹簧离合器的使用寿命，使膜片弹簧离合器在工作过程中处于最佳状态。关键词：离合器；膜片弹簧；摩擦片；参数设计。潍坊学院本科毕业设计2ABSTRACTAutomotiveisanintegralpartofmodernlifetransportation.Oflateyears,thedevelopmentindesignandmanufacturingtechniqueofautomobileisobvioustoall.Inordertoimproveproductperformanceandtoextendservicelife,techniqueonthegeneralmachineryclutchproducedattentionalchangestoo.Thetechniquedevelopmentofthemachineryclutch,whetheritsdesignfeature,processingpropertyorcontroltechnique,reflecteddevelopmentofthedesignconceptanditsfuturepossibletechniquetrendtoacertainextent.Theclutchisoneimportantpartintheautopowertrain,intheinternalcombustionengineasthepowerofmechanicaldriveauto,theclutchtookanindependentpartexists.Thispaperisthesingle-carthecaspringclutchdesign.Thecontentofclutchdesignmaincontainthreeparts:drivendiscdesign,diaphragm-springdesignandthedrivingdiscdesign.Fist,Thearticlestudiedineachclutchaccessory’smaterial,techniqueinmanufactureandmachiningandchoosingproject,thenusesthePro/EsoftwaretopicturethethreedimensionalimageoftheAssemblyandtheComponents.Finallythemechanismmovementsimulation.Thedesignoftheoriginaldesignoftheclutchtooptimizeandmodifytheproposal,itsfutureroleinthedesignprocessfromthereference.Thisarticleemphasizeinstudyingthediaphragm-springcharacteristic,analyzingthedynamicsandthemathematicsinseparationprocessstress,optimizingeverydateaboutthediaphragm-spring,forimprovinguselifetimeofdiaphragm-spring.Keywords:clutch;diaphragm-spring;frictiondisk;parameterdesign.潍坊学院本科毕业设计3目录1绪论.............................................................................................................................................................41.1离合器的发展...................................................................................................................................41.2离合器的工作原理...........................................................................................................................41.3离合器的功用及要求.......................................................................................................................51.4Pro/ENGINEER的介绍...................................................................................................................62离合器的结构方案设计.............................................................................................................................72.1从动盘的选择..................................................................................................................................72.2压紧弹簧和布置形式的选择..........................................................................................................72.3压盘驱动方式的选择.......................................................................................................................82.4离合器的散热通风..........................................................................................................................82.5膜片弹簧离合器的优点..................................................................................................................92.6确定离合器的类型..........................................................................................................................93离合器设计...............................................................................................................................................103.1离合器的基本参数及尺寸选择....................................................................................................103.2离合器从动盘总成的设计............................................................................................................123.3离合器压盘和离合器盖设计........................................................................................................193.4膜片弹簧的设计............................................................................................................................213.5离合器操纵系统的设计................................................................................................................274离合器的三维建模与动态仿真................................................................................................................294.1离合器的三维建模.........................................................................................................................294.2离合器的动态仿真........................................................................................................................38总结..............................................................................................................................................................41致谢.............................................................................................................................................................
