Driving Axle is consisted of Final Drive, Differential Mechanism, Half Shaft and Axle Housing. The basic function of Driving Axle is to increase the torque transmitted by Drive Shaft or directly transmitted by Gearbox, then distributes it to left and right wheel, and make these two wheels have the differential function which is required in Automobile Driving Kinematics; besides, the Driving Axle must also stand the lead hangs down strength, the longitudinal force and the transverse force acted on the road surface, the frame or partment lead. The configuration of the Driving Axle is introduced in the theses at first. On the basis of the analysis of the structure ,the developing process and advantages and disadvantages of the former type 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 stamp-welded steel sheet of Integral Axle Housing for Axle Housing. In the design, we plished the design for Single Reduction Gear, tapered ary Gear Differential Mechanism, Full-floating Axle, the checking of Axle Housing and CAD drawing and soon. . Key words: Drive a
