KD1060型货车驱动桥设计
摘要
驱动桥主要包括驱动桥壳、主减速器、差速器和两个后桥半轴,本次设计后桥为驱动桥。驱动桥是汽车传动系主要总成之一,具有承载车身和驱动汽车的功用。
根据本次设计的车型和技术参数要求及现有的生产技术水平,为降低生产成本,使该车具有良好的燃油经济性,操纵性和结构简单的特点,决定本次设计采用以下形式:差速器为普通对称式圆锥齿轮差速器;半轴的形式为全浮式半轴;驱动桥壳为焊接整体式桥壳。作为非断开式驱动桥。
因此驱动桥设计应当满足如下基本要求:
1. 所选择的主减速比应能保证汽车具有最佳的动力性和燃料经济性;
2. 外形尺寸要小,保证有必要的离地间隙;
3. 齿轮及其它传动件工作平稳,噪声小;
4. 结构简单,加工工艺性好,制造容易,拆装,调整方便。
在说明书的计算部分,说明了主要参数选择的依据,对主减速器,差速器,半轴和驱动桥壳进行了尺寸和强度计算。此外,还计算了主减速器支撑轴承的寿命。本文提供了关于以上计算的详细计算依据、步骤和计算数据。

DRIVING
AXLE DESIGN OF KD1060 TRUCK
ABSTRACT
The driving axle includes a shell of drive axle,a main decelerator, a differentional, and two axle shafts. The rear axle acts as the driving axle in this project. The rear axle is an ponent of the truck, which is used to bear the frame and drive the truck.
According the design of the car and the ability of the manufacture technology at the present,in order to deciline the cost of the production and make sure the car had a better quality and proper price,The type of the design as follow:mon symmetric conic gear differentional;the floating axle shaft;the welding banjo axle housing driving axle case.
So it needs some basic requirement to design.
1. We should choose suitable gear ratio ,so that we can get best dynamic property and fuel economy in giving special conditions;
2 .The small overall dimensions of vehicle can be sure enough ground clearance ;
3 .The gear and other driving parts work no vibration and noise ;
4 .The structure should be simple and the technological efficiency should be good .It also should be easy to repair and adjust .
The calculation section of this paper is mainly concerning about the physical dimension of the gear of the main drive, the diff, the driving axle, the driving axle housing and the strength of them. In addition, the life of the bearing of the main drive is also calculated in this section. Majority putations basis, the step and the estimated data for these project are advanced in paper.
KEY WORDS: driving axle,
