摘要
轻型汽车在商用汽车生产中占有很大的比重,而且驱动桥在整车中十分重要。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、高效益需要的同时时,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的轻型货车驱动桥具有一定的实际意义。
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
器的减速型式采用单级减速器,主减速器齿轮采用螺旋锥齿轮,差速器采用圆锥行星
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
完成了单级减速器、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。最后运用 AUTOCAD 完成装配图和主要零件图的绘制。

ABSTRACT
Pickup trucks take a large proportion mercial 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
ing the trucks’ developing tendency. Design a simple, reliable, low cost of the drive axle, can
greatly reduce the total cost of vehicle production, so the title of the fine structure of the design of a
pickup vehicle drive axle has a certain practical significance.
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,
Single 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, the checking of Axle Housing and the election of the material and so on.
