Steering Drive Axle include the main drive component, Differential, half axel, universal, Drive Axle Housing, etc. Driving Axle is one of the main assemble of the automotive power train. Whether the design of the Driving Axle is reasonable or not, affect the use of the cars. Driving Axle is the important part of the cars, it withstands the all force and torque between the road and the suspension and its working condition is the worst in cars. If the design is not right it will cause serious consequences. On the base of the Driving Axle traditional design methods, study the Steering Drive Axle design methods of the Magoton 1.8T carefully and give the practical design methods in this paper. According to this idea and the design data I draw out the parts diagram of the Steering Drive Axle. At the same time I also find the existing Magoton 1.8T sedan Driving Axle structure principle, and better und
