毕业论文（设计）题目9m空气悬架大客车后悬架设计系部汽车与交通工程系专业车辆工程年级大四学生姓名1111111111111学号2222222222222222指导教师3333333333333333汽车悬挂系统设计【摘要】：悬挂系统是指由车身与轮胎间的弹簧和避震器组成的整个支持系统。悬挂系统的功能是支持车身，改善乘坐的感觉，不同的悬挂设置会使驾驶者有不同的驾驶感受。外表看似简单的悬挂系统综合多种作用力，决定着轿车的稳定性、舒适性和安全性，是现代轿车十分关键的部件之一。论文回顾了汽车悬挂系统的发展历程，介绍了悬挂系统的分类和组成，详细分析了各种悬挂系统的优劣，进行了对比。最后根据汽车的要求，选定了悬挂系统的组合，前悬架为麦弗逊式独立悬挂，后悬架为钢板弹簧整体式悬挂。并且确定了前后悬挂的技术参数，在设计中着重考虑了汽车的稳定性和操控性，对整个系统进行了运动学和力学分析计算。最后使用AUTOCAD绘制出了汽车悬挂的装配图和部分零件图。【关键字】:汽车悬挂独立悬挂非独立悬挂麦弗逊式独立悬挂钢板弹簧整体式悬挂TheDesignOfCarSuspensionSystem【Abstract】Suspensionismeansthatthebodyandtiresbetweenspringandshockabsorberfortheentiresupportsystem.Thefunctionofsuspensionsystemistosupportthebody,improvetheridefeeldifferentsuspensionsettingsthedriverwillhavedifferentdrivingexperience.Appearedtobeasimplesuspensionsystemintegratedavarietyofforces,determinethecar'sstability,comfortandsafetyofmoderncarsisoneofkeycomponents.Thisthesisreviewsthedevelopmenthistoryofthesuspensionsystemsandintroducestheclassificationandcompositionofit.Secondly,thethesisdetailedanalysistheprosandconsofvarioussuspensionsystems,werecompared.Finally,accordingtotherequirementsofvehicles,decidedonacombinationofthesuspension,frontsuspensionisMcPhersonindependentsuspension,leafspringrearsuspensionforthewholesuspension.Anddeterminedthetwosuspensionsofthetechnicalparametersconsideredinthedesignfocusedonstabilityandcontrolofthecar,thewholesystemofcalculationofthekinematicsandmechanics.FinallyoutofthecarhangingAUTOCADdrawing,assemblydrawingandpartofthepartsdrawing.【Keywords】:carsuspensionsystem;independentsuspension;solidaxlesuspension;macphersontype;leaf-springdependentsuspension目录【摘要】............................................................I1.绪论..........................................................-1-1.1汽车悬挂的基本原理.......................................-1-1.2汽车悬挂的发展史.........................................-2-2.汽车悬挂的组成和分类..........................................-4-2.1汽车悬挂的组成...........................................-4-2.2非独立悬架的类型及特点...................................-5-2.2,1钢板弹簧式非独立悬架...............................-5-2.2.2螺旋弹簧非独立悬架.................................-5-2.2.3空气弹簧非独立悬架.................................-6-2.3独立悬架的类型及特点.....................................-6-2.3.1双横臂式...........................................-7-2.3.2麦弗逊式（滑柱连杆式）.............................-8-2.3.3双叉臂式悬挂.......................................-9-2.3.4拖拽臂式悬挂......................................-12-2.3.5连杆支柱悬挂......................................-14-2.3.6多连杆独立悬挂....................................-15-3.悬挂系统的选择...............................................-18-3.1前独立悬架的选择........................................-18-3.2后悬架的选择............................................-19-3.3整车参数................................................-20-4.悬挂系统的计算...
