五菱宏光轻型货车机械式变速器设计摘要在汽车的传动系统中，变速器是无可替代的重要环节之一。无论是驾驶人的操作感受，还是汽车发动机性能的体现，亦或是汽车运行的稳定性等，均与变速器的技术参数和构造性能直接相关。汽车运行过程中，必须满足变速换挡、起步、倒挡等基本操作性能，故而利用总和设计变速器内部，从而实现简单、迅速、方便的操作流程。本次进行的变速器设计，充分结合了任务书中既定的基本参数，选取了五菱宏光这款车型作为设计的基础，翻阅了大量的专业书籍和国家相关标准，结合市场调研的情况，实现了变速器的完整设计。本次设计的主要内容为车辆手动变速器的研究，给予了变速器一个具体详尽的介绍，还针对变速器的换挡结构、传动机构和档位的布置等加以论述。与此同时，利用计算确认了变速器的齿轮结构等部分，还一并计算了车辆整体的中心距、传动比即各档位齿轮等，再次核算了零部件的计算内容，选择适用性、标准度更高的零部件。关键词：机械式变速器；中间轴；传动机构；设计AbstractTransmissioninthetransmissionsystemofvehicleisthemostimportantlink,itsstructureperformance,technicalparameterssuchastheexperienceofautomobileengineperformance,drivinghumanoperatingexperienceandthestabilityofthevehicletorunworkhasanimmediateimpact.Needtobeinthecarrunningstartandshiftgears,shiftingthebasicoperations,throughthetransmissionwithintheintegrateddesign,canmaketheengineissimple,convenientandrapidtoachievethebasicoperation.Thegraduationdesignaccordingtospecificationgivenbasicparameters,choosetheDF-xiaokangasthebasisofdesign,throughtotherelatedliteraturequeryandnationalstandardsoflearning,andthroughmarketresearch,itstransmissionisacompletedesign.ThegraduationdesignselectionofmodelsisbydF3R,thismodelismorecommonmodelsonthemarket.Inthisstudy,inviewoftheselectedmodelswascarriedoutdetailedanalysisandcalculation,especiallyforthegearparameters,thebasicparameters,suchastotaltransmissionratio,centerdistanceandtheintensity,etc.Basedontheresearchofthegraduationdesign,formedasystemoftransmission.Keywords:MechanicalMechanic;IntermediateShaft;DesignChecking;TransmissionMechanism目录摘要.................................................................................................................................................1Abstract............................................................................................................................................1第1章绪论....................................................................................................................................11.1研究目的和意义.................................................................................................................11.2研究现状.............................................................................................................................11.3设计的主要内容................................................................................................................21.4本章小结............................................................................................................................2第2章总体方案设计....................................................................................................................42.1基本设计参数....................................................................................................................42.2设计变速器的基本要求....................................................................................................42.3变速器结构分析...............
