摘 要
福田歐曼ETX在汽車生產(chǎn)中占有很大的比重，而且驅(qū)動橋在整車中十分重要。驅(qū)動橋作為汽車四大總成之一，它的性能的好壞直接影響整車性能，而對于載貨汽車顯得尤為重要。為滿足目前當(dāng)前載貨汽車的快速、高效率、高效益的需要時，必須要搭配一個高效、可靠的驅(qū)動橋。設(shè)計出結(jié)構(gòu)簡單、工作可靠、造價低廉的驅(qū)動橋，能大大降低整車生產(chǎn)的總成本，推動汽車經(jīng)濟的發(fā)展，并且通過對汽車驅(qū)動橋的學(xué)習(xí)和設(shè)計實踐，可以更好的學(xué)習(xí)并掌握現(xiàn)代汽車設(shè)計與機械設(shè)計的全面知識和技能，所以本題設(shè)計一款結(jié)構(gòu)優(yōu)良的輕型貨車驅(qū)動橋具有一定的實際意義。
本文首先確定主要部件的結(jié)構(gòu)型式和主要設(shè)計參數(shù)，在分析驅(qū)動橋各部分結(jié)構(gòu)形式、發(fā)展過程及其以往形式的優(yōu)缺點的基礎(chǔ)上，確定了總體設(shè)計方案，采用傳統(tǒng)設(shè)計方法對驅(qū)動橋各部件主減速器、差速器、半軸、橋殼進行設(shè)計計算并完成校核。最后運用AUTOCAD完成裝配圖和主要零件圖的繪制。

ABSTRACT
Fukuda lehman ETX take a large proportion of commercial vehicles production, and the drive axle is one of the most important structure. 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 today` truck, must exploiting the high driven efficiency single reduction final drive axle is becoming the trucks’ developing tendency. 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 a comprehensive knowledge and skills, so the title of the fine structure of the design of a pickup vehicle drive axle has a certain practical significance.
In this paper, first of all determine the structure of major components 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 and complete the check. Finally complete the final assembly drawing by using AUTOCAD and mapping the main components.
