安徽工程大学毕业设计(论文)小型汽车自动变速器设计摘要自动变速器包括了许多组件和系统的协同工作，有行星齿轮组、液压系统、密封件和垫圈、变矩器、调节器、节气门拉线、计算机控制这些都是多年来由机械式演变过来的。自动变速器车轮包含许多不同的组合，在一个变速箱内，齿轮的滑动沿轴线从一个位置到另一个位置，对各种大小齿轮的要求，有正确的传动比。在一个自动变速箱，至始至终，不是齿轮的机械移动来达到这一点的，通过行星齿轮组来完成。关键词：自动变速器；液力变矩器；油泵；行星齿轮机构I安徽工程大学毕业设计(论文)ThedesignofsmallvehicleautomatictransmissionAbstractTheautomatictransmissionconsistsofmanycomponentsandsystemsthatdesignedtoworktogetherinasymphonyofplanetarygearsets,thehydraulicsystem,sealsandgaskets,thetorqueconverter,thegovernorandthemodulatororthrottlecableandcomputercontrolsthathasevolvedovertheyearsintowhatmanymechanicalinclinedindividualsconsidertobeanartfrom.Automatictransmissioncontainmanygearsinvariouscombinations.Inamanualtransmission，gearsslidealongshaftsasyoumovetheshiftleverfromonepositiontoanother,engagingvarioussizesgearsasrequiredinordertoprovidethecorrectgearratio.Inanautomatictransmission,however,thegearsareneverphysicallymovedandarealwaysengagedtothesamegears.Thisisaccomplishedthroughtheuseofplanetarygearsets.KeyWords:Automatictransmission；Hydraulictorqueconverter；Pump；PlanetarygearsII安徽工程大学毕业设计(论文)目录第1章自动变速器概述.....................................................................................................................-1-1.1自动变速器的发展历史................................................................................................................-1-1.2自动变速器的分类.........................................................................................................................-2-第2章自动变速器的基本组成.......................................................................................................-4-第3章液力自动变速器工作原理...................................................................................................-7-第4章液力自动变速器液控系统...................................................................................................-9-4.1油泵....................................................................................................................................................-9-4.2主油路系统......................................................................................................................................-9-4.3换档信号系统................................................................................................................................-10-4.4换档阀系统.....................................................................................................................................-11-4.5缓冲安全系统................................................................................................................................-12-4.6液力变距器控制装置..................................................................................................................-13-4.7液控系统的工作原理..................................................................................................................-13-第5章液力变矩器............................................................................................................................-14-5.1...
