某重型卡车驱动桥的设计

摘要：汽车后桥是汽车的主要部件之一，其基本的功用是增大由传动轴或直接由变速器传来的转矩，再将转矩分配给左右驱动车轮，并使左右驱动车轮具有汽车行驶运动所要求的差速功能:同时，驱动桥还要承受作用于路面和车架或承载车身之间的铅垂力、纵向力，横向力及其力矩。其质量，性能的好坏直接影响整车的安全性，经济性、舒适性、可靠性。

本文认真地分析参考了江淮HF15015卡车驱动桥以及韩国现代468号驱动桥，在论述汽车驱动桥运行机理的基础上，提练出了在驱动桥设计中应掌握的满足汽车行驶的平顺性和通过性、降噪技术的应用及零件的标准化、部件的通用化、产品的系列化等三大关键技术；阐述了汽车驱动桥的基本原理并进行了系统分析；根据经济、适用、舒适、安全可靠的设计原则和分析比较，确定了重型卡车驱动桥结构形式、布置方法、主减速器总成、差速器总成、桥壳及半轴的结构型式；并对制动器以及主要零部件进行了强度校核，完善了驱动桥的整体设计。

通过本课题的研究，开发设计出适用于装置大马力发动机重型货车的单级驱动桥产品，确保设计的重型卡车驱动桥经济、实用、安全、可靠。

Abstract: Drive axle is one of the most important parts of automobile. The function is to increase the torque from drive shaft or from transmission directly, and then

distribute it to left and right wheels which have the differential ability

automobile needed when driving. And the drive axle has to support the

vertical force, longitudinal force, horizontal force and their moments

between road and frame or body. Its quality and performance will affect the

security, economic, comfortability and reliability.

This article analyzes and refers to the drive axle of Jianghuai HF15015 truck and the 468 drive axle of Hyundai seriously. Through the study of this

topic, we can design the single driving axle devices that apply to the heavy

truck with high-powered engine, and make sure the drive axle we design of

heavy truck economic, practical, safe and reliable.On talking about the

running principal of driving axle ,the three key techno ledge about vehicle

traveling on the ride and through, and noise reduction technology

applications and the standardization of parts, components of the universal,

Products such as the serialization that we should master to meet, it describes

and has a systematic analysis on the basic principles of viecle drive axle.

According to the design principles and analysis and comparison of economy, application, comfortability, safety and reliability , the heavy truck

drive axle structure, layout ways, and the final drive assembly, differential

assembly, the bridge case and axle structure can be determined; and the

strength checking of brake parts, as well as major components improves

overall design of the driving axle.

Through the study of this topic, we can design the single drive axle devices that apply to the heavy truck with high-powered engine, and make

sure the drive axle we design of heavy truck economic, practical, safe and

reliable.
