1、摘要汽车悬架设计专业：车辆工程学号：20080310150223学生姓名：杨波指导老师：程贤福摘要悬架是现代汽车上的重要组成之一，它把车架（或车身）与车轴（或车轮）弹性地连接起来。其主要任务是传递作用在车轮和车架（或车身）之间的一切力和力矩；缓和路面传给车架（或车身）的冲击载荷，衰减由此引起的承载系统的振动，保证汽车的行驶平顺性；保证车轮在路面不平和载荷变化时有理想的运动特性，保证汽车的操纵稳定性，使汽车获得高速的行驶能力。本次毕业设计是采用前悬麦弗逊式独立悬架。麦弗逊式独立悬架有着结构简单、紧凑、占用空间小等众多优点，在现在轻型汽车中得到广泛运用。通过给

2、定的捷达汽车前悬架的相关参数，对前悬架的关键零部件螺旋弹簧、横向稳定杆、减振器等进行设计计算、选型和校核；并对导向机构进行受力分析和分析悬架的结构特点。关键词：汽车前悬架；麦弗逊式独立悬架；设计计算ⅠAbstractAutomobilesuspendedframedesignAbstractSuspensionistheimportantpartinthemoderncar,whichhasoneoftheframe(orbody)andaxle(orwheel)elasticconnect.Itsmaintaskistotransferfunctioni
