摘要
驱动桥作为汽车四大总成之一,它的性能的好坏直接影响整车性能,而对于载货
汽车显得尤为重要。为满足目前当前载货汽车的快速、高效率、高效益的需要时,必
须要搭配一个高效、可靠的驱动桥。设计出结构简单、工作可靠、造价低廉的驱动桥,
能大大降低整车生产的总成本,推动汽车经济的发展。
本文首先确定主要部件的结构型式和主要设计参数,在分析驱动桥各部分结构形
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,采用传统设计
方法对驱动桥各部件主减速器、差速器、半轴、桥壳进行设计计算并完成校核。最后
运用 AUTOCAD 完成装配图和主要零件图的绘制。并且通过对汽车驱动桥的学习和设
计实践,可以更好的学习并掌握现代汽车设计与机械设计的全面知识和技能,所以本
题设计一款结构优良的中型货车驱动桥具有一定的实际意义。

ABSTRACT
Drive axle is the one of automobile four important assemblies, its performance directly
influence on the entire automobile, especially for the truck .Because using the big power
engine with the big driving torque satisfied the need of high speed, heavy-loaded, high
efficiency, high benefit todays` truck, must exploiting the high driven efficiency single
reduction final drive axle is ing the trucks’ developing tendency.
In this paper, first of all determine the structure of ponents and the main
design parameters, the analysis of the various parts of the structure of the bridge drive type,
the form of the development process and its advantages and disadvantages of the past,
determined on the basis of the design program, using the traditional design method of
various parts of the drive axle Main reducer, differential, axle, axle housing was designed to
calculate plete the check. plete the final assembly drawing by using
AUTOCAD and mapping the ponents. Design a simple, reliable, low cost of the
drive axle, can greatly reduce the total cost of vehicle production, and promote the
economic development of automobile and automotive drive axle of the study and design
practice, can better learn and to master modern automotive design and mechanical design of
prehensive knowledge and skills, so the title of the fine structure of the design of a
pickup vehicle drive axle has a certain practical significance.
