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, exploiting the high driven efficiency single reduction final drive axle is becoming the trucks’ developing tendency. In this paper, first of all determine the structure of major components and the main design parameters, determined on the basis of the design program, using the traditional design method of various parts of the drive axle Main reducer, differential, axle, axle housing was designed to calculate and complete the check. Finally complete the final assembly drawing by using AUTOCAD and mapping the main components. Keywords：Drive Hxle; Reduction Final Drive; Differential; Axle; Drive Axle Housing -3-
