Drive axle as an one important part of the car chassiss, 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, high efficiency, high benefit today` truck, must exploiting the high driven efficiency single reduction final drive axle is becoming the trucks’ developing tendency. 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 automotive drive axle of the study and design practice, can better learn and to master modern automotive design and mechanical design of a comprehensive knowledge and skills, so the title of the fine structure of the design of a vehicle drive axle has a certain practical significance. 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
