摘 要
近年来，汽车已经成为重要的交通运输工具，但是汽车排放的污染物增多对环境
造成严重危害，如何提高汽车的燃油经济性，降低污染物，成为当下首要解决的问题。
驱动桥作为汽车传动系统的一部分，并且是汽车底盘的重要零部件，它对汽车燃油经
济性、动力性、操纵稳定性和实用性等其它方面的性能有着重要的影响。而桥壳是驱
动桥总成其它零件装配的基体,它既是承载件又是传力件，工作环境十分恶劣。所以，
桥壳应具备可靠的强度、刚度，才能满足汽车良好动态性能的要求。因而设计一款性
能良好的驱动桥成为当下解决问题的方法之一。
本文以东风柳汽乘龙 H5 重型仓栅货车为研究对象，参考同类车型拟定参数，查阅
相关文献，确定驱动桥的结构形式采用非断开式；计算主减速比，确定主减速器的结
构形式为单极主减速器，再进行相关的强度、参数计算和校核；确定差速器的结构形

Abstract
In recent years, automobiles have become an important means of transportation, but the
increase of pollutants emitted by automobiles has caused serious harm to the environment.
How to improve the fuel economy of automobiles and reduce pollutants has become the
primary problem to be solved at present. As a part of the automobile transmission system, and
is an important part of the automobile chassis, it has an important impact on the vehicle fuel
economy, power, handling stability and practicability and other aspects of the performance.
The axle housing is the matrix for the assembly of other parts of the drive axle assembly. It is
both the bearing part and the force transmission part, and the working environment is very
bad. Therefore, the axle housing should have reliable strength and stiffness to meet the
requirements of good dynamic performance of the vehicle. Therefore, the design of a good
performance of the drive axle has become one of the current solutions to the problem.
In this paper, Dongfeng Liuqi Chenglong H5 heavy-duty warehouse grid truck as the
research object, reference to similar models to formulate parameters, refer to the relevant
literature, to determine the transaxle structure of the non-breaking type; Calculate the main
reduction ratio, determine the structure of the main reducer for the single pole main reducer,
and then related strength, parameter calculation and check; The structure of the differential is
determined to be a symmetrical bevel gear differential with friction components, and then the
related strength check calculation; The semi-shaft structure is selected as full floating type,
and then the related design calculation and check are carried out. The driving axle housing
structure is determined to be integral, and the corresponding stress conditions under three
typical working conditions are calculated. Through the joint simulation of SolidWorks and
ANSYS, the 3D model data of the drive axle housing was established in the 3D modeling
software, which was imported into ANSYS for finite element analysis, three typical working
conditions were set, and the stress-strain cloud diagram of the drive axle housing was
simulated. Analysis proves that the target drive axle assembly design meets the design
requirements, the drive axle housing has good strength and stiffness, driving under multiple
conditions are reliable, so it can better meet the vehicle power, fuel economy, handling
stability and practicability of other aspects of the performance.
