Drive axle design for 1.6 liter sedan
Abstract
With the development of the automobile industry and the continuous improvement of productivity, the dynamic performance of the car attracts more and more attention from people, while the good dynamic performance does not only result the performance of the engine, but also the entire power system, where drive axle plays a very important role.Located at the end of transmission, drive axle can change the transmission speed and torque, and delivers them to the drive wheel mechanism. Composed offinal drive, differential, wheel drive, drive axle housing,semi axle and constant velocity universal joint, its components also play a vital part in vehicle. Like the drive bridge acts on the transport of vertical force, longitudinal force and lateral force, as well as braking torque and reaction force between the road surface and the frame or the body. Therefore, the design of drive axle plays an important part in vehicle design.
This design refers to the design of the traditional drive axle, and carries on the the 1.6 liter traditional sedan car. As all through the relevant parameters are given, we should determine the structure design of the drive axle like the single-stage final drive, symmetrical bevel gear differential, full floating semi axle structure; then calculate the final drive, differential, semi axle and other parts of the main parameters and determine its the sizewithin structures, and do strength check, in order to meet the design requirements. To finish 3D geometry model of all parts we are using the three-dimensional modeling software CATIA and CAD, to draw the differential straight bevel gear and hypoid gear reducer using parametric modeling.
Key Words:Drive axle; Final drive; Differential; CATIA; CAD
