摘要随着汽车行业的不断发展，随之而来的汽车维修的任务也愈来愈重。在汽车举升机没有出现之前，一般汽车维修工人都要趴在汽车底盘下面进行维修，在这样的环境下，不但维修活动范围受到限制，而且维修质量、维修效率也同样受到一定程度的影响。随着汽车维修业的迅猛发展，这样的维修方法已经不能够满足繁忙的汽车维修工作。于是就有了汽车举升机的出现，这种机器是将整辆汽车举升到一定高度，这样可以使维修工人很方便的在汽车底部工作。本设计是四柱液压汽车举升机的结构设计，首先对题目进行分析，再结合现有的汽车举升机的结构和液压系统，加上对汽车举升机的深入研究，然后对其中的方案进行拟定选择，并且对其中的重要零部件进行设计校核，并且画出装配图及零件图，从而将四柱液压汽车举升机设计完成。关键词：汽车维修四柱液压举升机-2-AbstractWiththecontinuousdevelopmentoftheautomotiveindustry,followedbythevehiclemaintenancetasksalsoincreasing.Beforethelifedidnotappear,Thegeneralvehiclemaintenanceworkersmustexpenseunderthecarbelowthechassisformaintenance,intheenvironment,notonlymaintenanceactivitieswererestricted,andmaintenanceofqualityandefficiencyofmaintenanceisalsotoacertainextentaffected.Asthevehiclemaintenanceindustryisrapidlydeveloping,themaintenanceofthishasnotbeabletomeetpeakofvehiclemaintenancework.Sothereistheemergenceoftheautomobilelift,thismachineistogivethewholevehiclesrosetoacertainheight,somaintenanceworkerscanmakeitconvenienttoworkinthecaratthebottom.Thedesignisoffour-posthydrauliccarliftthestructuraldesign,thefirsttopicforanalysis,combinedwiththeexistingcarliftthestructureandthehydraulicsystem,coupledwiththecarlift-depthresearch,andthenTheprogrammefordevelopmentofchoice,andoneoftheimportantpartsofthedesignverification,andpaintedpartsandassemblyplans,whichwillliftoffour-posthydrauliccardesigniscompleted.KeyWords:VehicleMaintenance，Four-Post，Hydraulic，Lift-3-目录摘要........................................................................................................................................................-1-ABSTRACT........................................................................................................................................................-2-前言........................................................................................................................................................-4-§1设计要求.................................................................................................................................................-6-§1.1该机的用途.........................................................................................................................................-6-§1.2该机的工作原理.................................................................................................................................-6-§1.3设计技术参数及要求.........................................................................................................................-6-§2该机主要参数的确定............................................................................................................................-7-§2.1汽车的主要参数................................................................................................................................-7-§2.2各种小型汽车的主要参数.................................................................................................................-9-§2.3对该机主要参数的初步确定...........................................................................................................-10-§3方案的确定............................................................................................................................................-12-§3.1联动装置方案的确定.......................................................................................................................-12-§3.2驱动机构方案的确定.......................................................................................................................-12-§3.3导向装置方案的确定.......................................................................................................................-13-§3.4安全保险机构...................................................................................................................................-13-§4重要零件的设计计算............................................................................................................................-14-§4.1对托架进行设计计算.......................................................................................................................-15-§4.2对升降架进行设计计算...................................................................................................................-17-§4.3对立柱进行设计计算.......................................................................................................................-20-§4.4对钢丝绳进行设计计算...................................................................................................................-22-§4.5对滑轮的转轴进行设计计算...........................................................................................................-22-§4.5.1活塞杆端部滑轮的转轴.........................................................................................................-23-§4.5.2需要绕过两根钢丝绳的滑轮的转轴：..................................................................................-24-§4.5.3有一根钢丝绳绕过的滑轮的转轴：......................................................................................-27-§5重要机构的设计计算............................................................................................................................-29-§5.1
