Driving Axle is consisted of Main Decelerator, 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 the partment lead. 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 acplished the design for Double Reduction Gear, tapered Plaary Gear Differential Mechanism, Full Floating Axle, the checking of Axle Housing and the election of the material and so on.
