东风EQ1135F19D中型货车膜片弹簧离合器设计

黑龙江工程学院本科生毕业设计I摘要汽车离合器位于发动机和变速箱之间的飞轮壳内，用螺钉将离合器总成固定在飞轮的后平面上，离合器的输出轴就是变速箱的输入轴。在汽车行驶过程中，驾驶员可根据需要踩下或松开离合器踏板，使发动机与变速箱暂时分离和逐渐接合，以切断或传递发动机向变速器输入的动力。目前，各种汽车广泛采用的摩擦离合器是一种依靠主从动部分之间的摩擦来传递动力且能分离的装置。本设计主要是对中型货车的膜片式弹簧离合器进行设计。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，首先进行了基本参数的选择，其次对零部件设计：压盘、离合器盖、弹性传动片，分离装置，以及从动盘、从动片和从动盘毂，操纵机构，扭转减震器中的螺旋弹簧的设计。根据各零部件的工作条件，并对其进行了相关校核。确保所设计的离合器能最大限度传递发动机的输出转矩。关键词：压盘；膜片弹簧；摩擦片；操纵机构；离合器黑龙江工程学院本科生毕业设计IIABSTRACTAutomobileclutchgearboxislocatedbetweentheengineandflywheelshell,withscrewassemblywillbefixedintheclutchaftertheplaneoftheflywheel,clutchgearboxoutputshaftistheinputshaft.Inthecar,thedrivercanbedownorreleasetheclutchpedal,sothatthetemporaryseparationoftheengineandgearbox,andthegradualbondingtocutoffortransfertheenginetothetransmissioninputpower.Atpresent,widelyusedinallkindsofcarsonfrictionclutchisamovingpartofthefrictionbetweenthesubordinatetotransferpowerandcanseparatedevice.Thisdesignismainlytothemediumtruckloadsofdiaphragmtypespringclutchonthedesign.Accordingtotheusingconditionsandvehicleparametersofvehicles,accordingtoclutchsystemdesignstepsandrequirements,thebasicparametersofthefirstchoice,secondtopartsdesign:pressureplate,clutchcover,elastictransmissionpiece,separationdevice,anddrivenplate,drivenplateandplatenhub,operation,reversedesignofthespiralspringshockabsorber.Accordingtovarioussparepartsworkingconditions,andanalysestherelevantrespectively.Ensurethatthedesignoftheclutchcanutmosttransferenginetorque.Keywords:PressurePlate;DiaphragmSpring;FrictionDisc;Controlagencies;Clutch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.......................................................................................................11.1离合器的研究背景...................................................................................................11.2国内外研究现状.......................................................................................................31.3离合器设计的主要内容...........................................................................................4第2章离合器方案设计及功能......................................................................52.1膜片弹簧离合器结构以及运动方式........................................................................52.2膜片弹簧离合器性能构造........................................................................................62.3膜片弹簧离合器工作原理.......................................................................................62.4膜片弹簧离合器的优点...........................................................................................62.5膜片弹簧离合器设计基本要求...............................................................................72.6本章小结...................................................................................................................7第3章膜片弹簧离合器零部件的结构设计..................................................93.1摩擦片基本结构尺寸参数的选择...........................................................................93.2从动盘总成设计........................................................................错误!未定义书签。3.2.1从动片设计......................................................................错误!未定义书签。3.2.2从动盘毂设计..................................................................错误!未定义书签。3.3压盘设计....................................................................................错误!未定义书签。3.3.1压盘参数的选择和校核..................................................错误!未定义书签。3.3.2传动片设计......................................................................错误!未定义书签。3.3.3离合器盖设计..................................................................错误!未定义书签。3.4离合器分离装置的设计............................................................错误!未定义书签。3.4.1分离轴承及分离套筒......................................................错误!未定义书签。3.4.2分离轴承的设计计算......................................................错误!未定义书签。3.5膜片弹簧的设计........................................................................错误!未定义书签。黑龙江工程学院本科生毕业设计3.5.1膜片弹簧结构形状的特点..............................................错误!未定义书签。3.5.2膜片弹簧的变形特性......................................................错误!未定义书签。3.5.3膜片弹簧基本参数的选择..............................................错误!未定义书签。3.5.4膜片弹簧参数的校核......................................................错误!未定义书签。3.5.6膜片弹簧的强度计算......................................................错误!未定义书签。3.6扭转减振器设计.....................................................................................................113.6.1扭转减振器的功能.......................................................................................113.6.2扭转减振器的结构类型的选择...................................................................113.6.3扭转减振器参数确定...................................................................................133.7本章小结.................................................................................................................17第4章离合器操纵机构设计...........................................................
