轻型货车离合器的设计.doc

轻型货车离合器的设计摘要离合器装在发动机与变速器之间,汽车从启动到行驶的整个过程中,经常需要使用离合器。它的作用是使发动机与变速器之间能逐渐接合,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。所设计的离合器是膜片弹簧离合器,此设计说明书详细的说明了轻型汽车膜片弹簧离合器的结构形式,参数选择以及计算过程,按照离合器系统的设计步骤和要求,对摩擦片外径D的确定,离合器后备系数b的确定,单位压力p的确定,以及从动盘设计包括从动片设计和从动盘毂设计,主动部分的设计,包括压盘、离合器盖设计、弹性传动片设计,其中离合器盖的设计只是简单的设计,操纵机构的设计是大体上计算出踏板的行程、踏板力,是否符合人体工程学要求。关键词:离合器;设计;膜片弹簧;从动盘;压盘;摩擦片ABSTRACTThecouplinginstallsbetweentheengineandthetransmissiongearbox,theautomobilefromthestarttothetravelentireprocess,,thusguaranteedthattheautomobilestartssteadily;Shutsoffbetweentheengineandtransmissiongearbox’srelationtemporarily,isadvantageousshiftsgearsandreducesshiftsgearsthetimeimpact;Whenautomobileemergencybrakecanplaytheseparationrole,preventstransmissionsystemsandsoontransmissiongearboxtooverload,,thedesignmanualdetailedtheprocessofthediaphragmspringclutchdesigningoflightvehiclestructure,includingparameterselectionandcalculationprocess,thedeterminationoffrictionplatediameter,back-hepressure,aswellasthefollowerplatefollowerpiecedesignincludesthedesignandthedesignofthedrivenwheeldisc,partofthedesignoftheinitiative,includingthepressureplate,Clutchcoverdesign,flexibledrivechipdesign,whichcoveredthedesignoftheclutchisasimpledesign,isdesignedtomanipulatethewholebodyoutofthetrippedal,pedalpower,:Clutch;Design;DiaphragmSpring;DrivenPlate;PressurePlate;„………………………………………………………„……………………ⅠAbstract„„„„„„„„„„„„„„„„„„„„„„„„„„„„„„Ⅱ第1章绪论„……„„„„„„„„„„„„„„„„„„„„„„„„…„„„„„„„„„„„„„„„„„„„„„…„„„„„„„„„„„„„„„„„„„„„…„„„„„„„„„„„„„„„„„„„………2第2章离合器主要结构的选取„„„„„„„„„„„„„„„„„„…„„„„„„„„„„„„„„„„„„„„…………„„„„„„„„„„„„„„„„„„„…………„„„„„„„„„„„„„„„………„„„„„„„„„„„„„
