黑龙江工程学院本科生毕业设计I摘要本次设计的题目是哈飞民意汽车驱动桥设计。驱动桥一般由主减速器、差速器、半轴及桥壳四部分组成,其基本功用是增大由传动轴或直接由变速器传来的转矩,将转矩分配给左、右车轮,并使左、右驱动车轮具有汽车行驶运动学所要求的差速功能;此外,还要承受作用于路面和车架或车厢之间的铅垂力、纵向力和横向力。本设计首先论述了驱动桥的总体结构,在分析驱动桥各部分结构型式、发展过程及其以往形式的优缺点的基础上,确定了总体设计方案:采用整体式驱动桥,主减速器的减速型式采用单级减速器,主减速器齿轮采用螺旋锥齿轮,差速器采用普通对称式圆锥行星齿轮差速器,半轴采用半浮式型式,桥壳采用钢板冲压焊接式整体式桥壳。关键词:驱动桥;主减速器;设计;计算;CAD黑龙江工程学院本科生毕业设计IIABSTRACTTheobjectofthedesignisthedesignfordrivingaxleofmini-carofSongHuajiangdrivingaxleisconsistedoffinaldrive,differentialmechanism,,thendistributesittoleftandrightwheel,andmakethesetwowheelshavethedifferentialfunctionwhichisrequiredinautomobiledrivingkinematics;besides,thedrivingaxlemustalsostandtheleadhangsdownstrength,thelongitudinalforceandthetransverseforceactedontheroadsurface,,thedevelopingprocessandadvantagesanddisadvantagesoftheformertypeofdrivingaxle,thedesignadoptedtheIntegraldrivingaxle,singlereductiongearformaindecelerator’sdecelerationform,spiralbevelgearformaindecelerator’sgear,halffloatingforaxleandstamp-,plishedthedesignforsinglereductiongear,arygeardifferentialmechanism,halffloatingaxle,thecheckingofaxlehousingandCADdrawingandsoon..Keywords:DrivingAxle;FinalDrive;Design;Calculation;CAD黑龙江工程学院本科生毕业设计目录第1章绪论................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
