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。

ABSTRACT
The object of the design is the design for driving axle of mini-car of SongHuajiang
driving axle is consisted of final drive, differential mechanism, half shaft and axle housing.
The basic function of driving axle is to increase the torque transmitted by drive shaft or
directly transmitted by gearbox, then distributes it to left and right wheel, and make these
two wheels have the differential function which is required in automobile driving kinematics;
besides, the driving axle must also stand the lead hangs down strength, the longitudinal
force and the transverse force acted on the road surface, the frame or partment lead.
The configuration of the driving axle is introduced in the thesis at first. On the basis of
the analysis of the structure ,the developing process and advantages and disadvantages of
the former type of driving axle, the design adopted the Integral driving axle, single
reduction gear for main decelerator’s deceleration form, spiral bevel gear for main
decelerator’s gear, half floating for axle and stamp-welded steel sheet of integral axle
housing for axle housing. In the design, we plished the design for single reduction
gear, tapered ary gear differential mechanism, half floating axle, the checking of axle
housing and CAD drawing and so on.
