Axle design is one of the important parts of automotive design, domestic drive axle in the domestic market accounted for the lions share, but there is still a certain number of axles dependent on imports, there is still a certain gap between domestic axle and the international advanced level. Firstly, this design is lookup of the domestic and international front drive axle design documents in recent years, integrated the knowledge of our expertise we had knew and mastered the car抯 front drive axle structure and working principle, formulated ac cording to the vehicle parameters to the corresponding design programs.Then referred to the relevant standard, manual data to determine the main design parameters of the main components of the drive axle, completed the structure and size of the steering, universal joints, main gear box, differential, axle and axle housing, and check, according to the calculated parameters selected to draw the overall steering drive axle assembly drawings, the differential assembly drawings as well as some parts diagram. There are three kinds of softwares used in this design, which are CATIA to model the axle, ANSY to accomplish the finite element analysis of the axle shell, and AutoCAD to draw assembly drawings and part drawings.
