大众速腾轿车离合器设计.docx

黑龙江工程学院本科生毕业设计I摘要离合器是汽车传动系中的重要部件,主要功用是是切断和实现发动机对传动系的动力传递,保证汽车平稳起步,保证传动系统换挡时工作平顺以及限制传动系统所承受的最大转矩,防止传动系统过载。膜片弹簧离合器是近年来在轿车和轻型汽车上广泛采用的一种离合器,它的转矩容量大而且较稳定,操作轻便,平衡性好,也能大量生产,对于它的研究已经变得越来越重要。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。本文主要是对轿车的膜片式弹簧离合器进行设计。根据推式膜片弹簧离合器工作原理和使用要求,采用系统化设计方法,把离合器分为主动部分、从动部分、操纵机构。通过对各个部分设计方案的原理阐释和优缺点的比较,确定了相关部分的基本结构及其零部件的制造材料。根据车辆使用条件和车辆参数,按照离合器系统的设计步骤和要求,主要进行了以下工作:选择相关设计参数主要为:摩擦片外径D的确定,离合器后备系数β的确定,单位压力P的确定。并进行了总成设计主要为:分离装置的设计,以及从动盘设计和膜片弹簧设计等。关键词:离合器;膜片弹簧;从动盘;压盘;摩擦片黑龙江工程学院本科生毕业设计IIABSTRACTAutomobileclutchisanimportantpartofthepowertrainofthecar,,usingthelearnedknowledgetothedesignprocess,,ordancewiththeclutchsystemdesignstepsandrequirementsforthefollowingmaintasks:choosingthemaindesignparametersare:thedeterminationoffrictionplatediameter,back-:thedesignofseparationdevices,aswellasthefollowerplatefollowerpiecedesignincludesthedesignandthedesignofthedrivenwheeldisc,partofthedesignoftheinitiative,includingthepressureplate,Clutchcoverdesign,flexibledrivechipdesign,whichcoveredthedesignoftheclutchisasimpledesign,isdesignedtomanipulatethewholebodyoutofthetrippedal,pedalpower,:Clutch;Diaphragmspring;Drivenplate;Pressurelate;Frictiondisc黑龙江工程学院本科生毕业设计目录摘要····························································································································IAbstract··························································································································II第1章绪论····························································································································································································································
