The rear axle acts as the driving axle in this project. The rear axle is an important component 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:the common 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 of computations basis, the step and the estimated data for these project are advanced in paper. KEY WORDS: driving axle, final drive, differential, rear suspension
