In this paper, first of all determine the structure of major components and the main design parameters, the analysis of the various parts of the structure of the bridge drive type, the form of the development process and its advantages and disadvantages of the past, 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. Design a simple, reliable, low cost of the drive axle, can greatly reduce the total cost of vehicle production, and promote the economic development of automobile and
