离合器摩擦片的设计和实现 车辆工程专业VIP免费

中文摘要离合器装在发动机与变速器之间。它的作用是使发动机与变速器之间能够逐渐接合，从而保证汽车平稳起步；暂时切断发动机与变速器之间的联系，以便于换档和减少换档时的冲击；当汽车紧急制动时能起分离作用，防止变速器等传动系统过载，起到一定的保护作用。为保证离合器有良好的工作性能，对汽车离合器的设计提出如下基本要求：1在任何行驶条件下，传递发动机最大扭矩的能力有适当的储备。2接合要平顺，以保证汽车起步的平稳。3分离时要彻底、迅速。4离合器从动部件的转动惯量要小，以便于换档和减少换档时齿轮的冲击。5应设有扭转减振阻尼装置，使汽车传动系统在工作转速范围内避免扭转共振。6具有良好的通风散热条件和必要的热容量，以保证离合器的工作温度不至于过高。7操纵轻便。8使用寿命要长，力求与汽车传动系统及其它总成等寿命。此外，也要离合器结构简单、紧凑，质量小，工艺性好，维修方便及适合大批量生产。关键词:离合器传动惯量齿轮发动机AbstractInstalledintheclutchbetweentheengineandtransmission.Itsroleistobebetweentheengineandtransmissionjointgradually,soastoensureasmoothstartcar;temporarilycutofftheengineandtransmissionwillbethelinkbetweentheshifttoshift,andtoreducetheimpactwhenthevehiclewhentheemergencybrakeIsolationcanplayroleinpreventingtransmission,andothertransmissionsystemoverload,playaprotectiverole.Toensureagoodworkingclutchperformance,thedesignoftheautomobileclutchmadethefollowingbasicrequirements:1inanydrivingconditions,enginetorquetransmissioncapabilityappropriatereserves.2engagementtorideinordertoensureasmoothstartcar.3separationshouldbethoroughandprompt.4clutchcomponentsfollowerofinertiatodrivesmall,inordertoshiftgearsandreducetheimpactwhentheshift.5Thereshouldbereversedvibrationdampingdevices,andenabletheautotransmissionspeedintheworkareatoavoidreverseresonance.6withgoodventilationcoolingthermalconditionsandthenecessarycapacitytoensurethatthetemperaturedoesnotclutchtoohigh.7manipulationoflight.8tolonglife,andautomobiletransmissiontoothertrains,suchaslifeexpectancy.Moreover,wehavetoclutchstructureissimple,compact,thequalityofsmall,technologyandgoodmaintenanceandsuitableformassproduction.Keywords:ClutchTransmissionofinertiaGearEngine目录中文摘要....................................................................................................1Abstract.......................................................................................................................2目录...........................................................................................................3第一章前言..............................................................................51.1离合器的概述......................................................................51.2离合器的功用和类型................................................51.2.1离合器功用..................................................................51.2.2离合器类型..................................................................51.3车辆离合器设计的基本要求.........................6第二章设计方案的选择................................................72.1整体方案的确定...............................................................72.2结构方案分析......................................................................82.2.1从动盘数的选择...................................................82.2.2压紧弹簧和布置形式的选择..............8第三章离合器摩擦片的设计.............................103.1确定已知参数................................................................
