汽车维修毕业论文NUMPAGES18--汽车维修毕业论文摘要转向系是汽车行驶的指南针，它的好坏关系着汽车能否安全行驶。本文首先讲述了爱丽舍转向系的整体结构；具体介绍了它的功用；分类和工作原理。然后具体对ELYSEE轿车转向系统常见的几种故障：一转向沉重，二转向时有噪声，三方向盘自由行程过大，四左右转向时轻重不一，五转向时转向盘强烈抖动，六汽车直线行驶时，转向盘发飘或跑偏。最后讲述了爱丽舍轿车转向系中转向盘的自由行程，转向储液罐的液面高度，液压泵的泵送压力，液压系统的密封性，转向柱的检查方法以及通过爱丽舍轿车转向系的故障现象进行了诊断分析和检修。对使用和维护汽车有着很现实的意义。关键词ELYSEE轿车轿车，转向器，故障分析，检查维修AbstractVehiclesteeringsystemisthecompass,itisgoodorbadrelationsbetweenthecarcandrivesafely.FirstdescribedinthispaperoftheElyseetotheoverallstructureofconcreteintroduceditsfunction;classificationandprinciple.AndthenthespecificELYSEEcarsteeringsystemfailureofseveralcommon:aheavyshift,theshiftfromtimetonoise,threefreetripoverthesteeringwheel,shiftatthelevelofaroundfourdifferentfive-strongsteeringwhenSteeringwheeljitter,sixcarlineInmotion,Steeringwheel,floatingordeviation.FinallyontheElyseesedanstotheDepartmentofsteeringwheelinthefreetriptothetanksurfaceheight,thehydraulicpumppumpingpressure,tightnessofthehydraulicsystem,themethodSteeringwheelElyseesedansaswellasthroughtheshiftoftheFailureofadiagnosticanalysisandmaintenance.Ontheuseandmaintenanceofmotorvehicleshasaverypracticalsignificance。KeywordsELYSEEpassengervehiclepassengervehicle,diverter,faultanalysis,inspectionservice目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc197706044"引言PAGEREF_Toc197706044\h4HYPERLINK\l"_Toc197706045"1转向系统的简介PAGEREF_Toc197706045\h5HYPERLINK\l"_Toc197706046"1.1转向系的工作原理PAGEREF_Toc197706046\h5HYPERLINK\l"_Toc197706047"1.2转向系的组成PAGEREF_Toc197706047\h5HYPERLINK\l"_Toc197706048"1.3转向系的分类PAGEREF_Toc197706048\h5HYPERLINK\l"_Toc197706049"1.4转向系的功用PAGEREF_Toc197706049\h5HYPERLINK\l"_Toc197706050"2东风·爱丽舍（ELYSEE）轿车转向系故障诊断分析6HYPERLINK\l"_Toc197706051"2.1转向沉重6HYPERLINK\l"_Toc197706052"2.1.1故障现象6HYPERLINK\l"_Toc197706053"2.1.2故障原因PAGEREF_Toc197706053\h6HYPERLINK\l"_Toc197706054"2.1.3故障诊断与排除6HYPERLINK\l"_Toc197706055"2.2转向时有噪声PAGEREF_Toc197706
