内容简介：

摘 要驱动桥是汽车的重要总成部件，也是汽车总成中的重要承载件，所以驱动桥的好坏直接影响着汽车整体的性能和零件的使用寿命等。驱动桥由主减速器、差速器、半轴及桥壳四部分组成，其基本功用是降速增扭，把发动机的动力传递给左右车轮，并使汽车在转向时保证左右车轮的差速功能，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，在分析了驱动桥的结构形式及优缺点后确定总体设计方案：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，差速器采用圆锥行星齿轮差速器，半轴采用全浮式型式，桥壳采用铸造整体式桥壳。本设计主要完成了单级减速器、圆锥行星齿轮差速器、全浮式半轴的设计和桥壳的校核及材料选取等工作。关键词：驱动桥；单级；主减速器；齿轮；材料；计算机辅助设计ABSTRACT Drive axle assembly is an important vehicle components, is also an important bearing in the vehicle assembly parts, so drive axle of a direct impact on overall vehicle performance and component life.Drive axle from the final drive, differential, axle and axle housing of four parts, the basic skills by using a spin-down twist, the engines power passed to the left and right wheels, and to ensure the car when the steering wheel left and right differential function, in addition, but also act on the road and bear the car frame or between the vertical force, vertical force and lateral force.Discusses the design of the first drive axle of the overall structure of the analysis of the drive axle of the structure and determine the advantages and disadvantages of design options: with integral drive axle, main reducer reducer reducer type single stage, the main spiral bevel gear reducer gears, planetary gear differential with conical differential, axle with full floating type, with cast axle Integral axle.The design was completed for a single-stage reducer, planetary gear differential cone, full floating axle half shaft design and Check and material selection and so on.Key
