杰德轿车驱动桥设计（汽车驱动桥含三维CATIA+CAD图纸说明书）

0三维预览(1)

本文通过对以往的驱动桥设计资料进行观阅和反思后，结合自己的杰德轿车的相关参数进行了比较合理的参数和结构设计，我在查阅资料的过程中反复思考杰德轿车的前桥的运作机理，并且平时对街头的车样进行查看，在学习实车的驱动桥布置以及架构的同时，思考我单独进行驱动桥的设计时。是否能够遵循设计的要求流程，是否能够完成它该有的功能，并在完成功能的同时考虑到零件的三化。这其中的关键便在于主减速器以及差速器的设计与搭配之上，作为驱动桥的灵魂部件，这两个结构的参数决定了整个驱动桥的尺寸和位置。因而在这两个结构的参数计算过程中，我严格查阅相关资料和参考导师的意见，进行多次修改来完成它的结构设计，并对它进行参数化建模。并且在这两个结构的基础上对其他组合部件进行设计以及建模，最后得到一个完整的驱动桥的模型，后续的CAD图也严格依照实际的三维建模而来。

Abstract
The drive axle is one of the four major assemblies of the car. It has a lot of parts and a complicated structure, and its performance will directly affect the performance of the whole vehicle.
In the car, the drive axle not only has to bear the load on the full load spring of the car, but also bears the plumb force and longitudinal force generated by the wheel through the wheel, the frame or the load-bearing body through the suspension. Moreover, the convenience of the transaxle from the conventional axle is that its location is directly related to the power output, so it needs to transmit torque for it, which is the maximum torque in the drive train.
After reviewing and reflecting on the past drive axle design data, this paper combines the parameters of the Jade sedan with reasonable parameters and structural design. At the same time, I also found the existing Jeddell's transaxle. The principle of structure, and through the street car to view and think, consider how I can complete a reasonable and dynamic, economical and other can basically meet the requirements of the transaxle design. The key to this is the design and matching of the final drive and the differential as the soul part of the drive axle. The parameters of these two structures determine the size and position of the entire drive axle. Therefore, in the parameter calculation process of these two structures, I strictly consult the relevant materials and the opinions of the reference instructors, and carry out several modifications to complete its structural design and parametric modeling.
