换挡机械手

长春工业大学学士论文Ⅰ摘要21世纪是汽车工业飞速发展的时代，汽车工业逐步成为许多国家的支柱产业。为了控制汽车产品质量，提高汽车品质，势必对其总成及零部件提出更高更严格的要求。变速器是汽车传动系中一个重要总成。同步器是汽车变速器的重要部件，主要用于汽车行驶中平稳变速换档，操纵轻便灵活，消除冲击噪音和降低汽车油耗。同时，防止变速箱齿轮的损坏，直接影响变速器寿命。因此，研制先进的同步器试验系统，对提高汽车试验技术有着重要意义。同时，汽车是一个由许多种零部件组成的复杂的机械系统。对于产品开发所需的许多技术资料，目前尚不能通过理论计算得到，只能通过试验，因此有人说“汽车是试验出来的”。国外汽车工业由于发展时间较长，且对试验检测工作十分重视，在资金上给予了巨大的投入，一般都有较为齐全的试验装备。再加上严格管理和精良的加工设备，与国内形成了较大的差距。所以，我国汽车厂必须加大对试验检测设备的投入，才能大大缩短同国外同类厂家在试验手段上的差距，有利于我国汽车产品在国内外的竞争能力。关键词：同步器机械手控制系统实验长春工业大学学士论文ⅡAbstractInthe21stcenturyistheeraofrapiddevelopmentofautomobileindustry,carindustryhasbecomethepillarindustryinmanycountries.Inordertocontrolthequalityofautomobileproductsimprovethequalityofthecar,isboundtotheassemblyandpartsputforwardhigherandmorestringentrequirements.Transmissionisanimportantassemblyintheautomobiledrivetrain.Synchronizerisoneoftheimportantparts,autotransmissionismainlyusedforthecaringearshiftsmoothly,flexiblemanipulation,eliminatethenoiseimpactandlowerfuelconsumption.Atthesametime,preventtransmissiongearisdamaged,directlyaffectingtheservicelifeofthetransmission.,therefore,todevelopadvancedsynchronizertestsystem,toimprovetheautotesttechnologyhasimportantsignificance.Atthesametime,theautomobileisacomplicatedmechanicalsystemiscomposedofmanykindsofspareparts.Formanyofthetechnicalinformationneededforproductdevelopment,atpresentcannotbeobtainedbytheoreticalcalculation,canonlythroughthetest,sosomepeoplesaythat\acaristest\.Foreignautomotiveindustrybecauseofthedevelopmentforalongtime,andtotestworkveryseriously,giventhehugeinvestmentinthecapital,usuallyhasrelativelycompletetestequipment.Coupledwiththestrictmanagementandexcellentprocessingequipment,withthedomesticformedalargergap.CarfactoryinChina,therefore,mustincreaseinvestmentintestequipment,andcangreatlyshortenthegapofsimilarforeignmanufactureronthetestmethod,isconducivetoChina'sautoproductsindomesticandinternationalcompetitionability.Keywords:SynchronizerManipulatorControlsystemExperiment长春工业大学学士论文1目录1绪论............................................................................................................................21.1同步器..................................................................................................................21.2变速器....................................................................................................................51.2.3自动变速器的分类........................................................................................61.2.4自动变速器的发展状况................................................................................71.2.5自动变速器未来的发展趋势........................................................................91.2.6实现车辆自动变速的意义..........................................................................101.3车辆自动换挡规律简介....................................................................................101.3.1单参数换挡规律..........................................................................................101.3.2两参数换挡规律..........................................................................................111.3.3三参数换挡规律..........................................................................................121.4设计任务..............................................................................................................131.5论文主要内容......................................................................................................132机械系统设计..........................................................................................................132.1机械系统的工作原理..........................................................................................142.2换档机构工作台机械部分设计..........................................................................152.2.1工作台外形尺寸及重量估算......................................................................152.2.2滚动导轨的参数确定..................................................................................152.3换档机构空间运动模型的简化..........................................................................172.4驱动系统的工作原理..........................................................................................192.5步进电机的选用..................................................................................................192.5.1电机外观......................................................................................................192.5.2技术参数......................................................................................................203电气系统设计..........................................................................................................243.1电气系统的组成..................................................................................................253.1.28255引脚功能............................................................................................263.1.3A/D转换器................................................................................................263.1.4力传感器.....................................................................................................273.2换档机构步进电机控制系统设计....................................................
