摘要
本次设计的题目是SX2190重型汽车驱动桥设计。驱动桥一般由主减速器、差速器、半轴及桥壳四部分组成,其基本功用是增扭、降速,改变转矩的传递方向,即增大由传动轴或直接从变速器传来的转矩,并将转矩合理地分配给左、右驱动车轮;其次,驱动桥还要承受作用于路面和车架或车身之间的垂直力、纵向力和横向力,以及制动力矩和反作用力矩等。
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双级减速器,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,半轴采用全浮式型式,桥壳采用铸造整体式桥壳。在本次设计中,主要完成了双级减速器、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。

ABSTRACT
This design topic is SX2190 heavy vehicle driving axle design. By main reducer, driving axle generally and half axle and bridge ponents, its shell basic function is increasing twist, slow down, change torque transmission shaft, namely, increasing the direction or directly from transmission by the torque, ing to a reasonable distribution of torque to left, right drive wheels; Secondly, to bear on the pavement drive axle of role and frame or body of vertical force, between the longitudinal force and transverse force, and braking torque and counterproductive torque, etc.
The configuration of the Driving Axle is introduced in the thesis at first. On the basis of the analysis of the structure and the developing process of Driving Axle, the design adopted the Integral Driving Axle, Double Reduction Gear for Main Decelerator’s deceleration form, Spiral Bevel Gear for Main Decelerator’s gear, Full Floating for Axle and Casting Integral Axle Housing for Axle Housing. In the design, we plished the design for Double Reduction Gear, tapered ary Gear Differential Mechanism, Full Floating Axle and Axle Housing.
