货车转向桥设计终

1货车转向桥设计摘要随着汽车行业的发展随着汽车行业的发展，作为汽车的关键零部件的转向桥也得到了相应的发展，基本以形成了专业化、系列化生产的局面。而且随着生产水平的发展，汽车的行驶速度不断提高，人们对汽车的性能要求也越来越高，如何保证既要具有较高的行驶速度又要具有良好的转向性能，就成了必须要解决的问题。本次设计为载重汽车的转向桥，此桥需要适应在不同的路况，不同的速度下使汽车保持稳定的行驶，并且使货车转向桥具有良好的稳定性和灵敏性。文中介绍了转向桥的概念，用途，总体布局，通过对前轴、转向节、转向梯形、主销等零件的尺寸和结构的设计，选择合适的材料，并对其进行强度的校核，以保证所本次设计的转向桥符合汽车道路行驶要求。关键词：转向桥；前梁；主销；定位参数1TheDesignofSteeringAxleTruckAbstractWiththedevelopmentoftheautomotiveindustry,asakeycomponentofthesteeringaxlecarhasalsobeenacorrespondingdevelopment,basictotheformationofaspecialized,seriesproductionofthesituation.Andwiththedevelopmentoftheproductionlevel,thetravelspeedcarcontinuestoimprove,peopleonthecar'sperformancerequirementsarealsoincreasing,howtoensurethatitisnecessarytohaveahighertravelspeedandalsohasgoodsteeringperformance,itbecomesnecessarytosolvetheproblem.Thedesignforthetruck'ssteeringaxle,thisbridgeneedstoadapttodifferentroadconditions,differentspeedsmakingthecarstableundertravel,andthesteeringaxletruckhasgoodstabilityandsensitivity.Thispaperintroducestheconceptofsteeringaxle,use,overalllayout,throughthefrontaxle,steeringknuckles,steeringthesizeandstructureofthetrapezoid,kingpinandotherpartsofthedesign,selectionofsuitablematerials,anditsstrengthandtheorderensurethatthedesignofthesteeringaxleinlinewiththerequirementsofautomobileroads.Keywords:initialvelocitymethod;gasemissionrate;minepanelI目录摘要...................................................................................................................................1Abstract..............................................................................................................................1第一章绪论.....................................................................................................................11.1汽车转向桥的概述.............................................................................................11.2转向桥的研究意义.............................................................................................11.3转向桥的发展背景.............................................................................................21.3.1转向系统发的发展历史..........................................................................21.3.2我国转向系统的发展..............................................................................21.4转向桥的分类与基本结构.................................................................................31.5典型车型前桥总成结构.....................................................................................3第二章转向桥的零件分析...........................................................................................52.1前梁.....................................................................................................................52.2转向节.................................................................................................................62.3转向梯形.............................................................................................................62.3.1整体式转向梯形......................................................................................62.3.2断开式转向梯形....................................................................................72.4主销.....................................................................................................................92.5转向节臂.............................................................................................................92.6轮毂组合.............................................................................................................92.7轴承...................................................................................................................102.7.1轮毂轴承................................................................................................102.7.2转向节止推轴承....................................................................................102.7.3主销轴承................................................................................................102.8转向拉杆总成...................................................................................................102.8.1转向球头................................................................................................112.8.2转向直拉杆............................................................................................112.8.3转向横拉杆............................................................................................112.9前轮摆振的机理...............................................................................................112.9.1自激摆振................................................................................................112.9.2受迫摆振................................................................................................12第三章转向桥的设计计算...........................................................................................133.1转向从东桥的主要零件尺寸的确定...............................................................133.1.1参考车型制动系相关主要参数数值....................................................133.1.2实际参数................................................................................................133.2转向
