汽车单级驱动桥总成设计(说明书+CAD装配图一张+三维图）_驱动桥壳参数图

摘 要

    本次设计为参照乘用轿车驱动桥来进行的，目的是为了检验大学几年的学习成果以及为将来的工作打下坚实的基础。说明书中阐述了驱动桥壳的功能与作用、设计的要求及其工作原理，通过查阅大量的汽车设计资料，以及结合所学的知识，对该驱动桥壳进行了方案论证、结构方案分析以及设计计算。本次设计的驱动桥采用半浮式半轴的整体式桥壳单级螺旋锥齿轮传动。普通对称式圆锥行星齿轮（两个）的差速形式。设计中包括了驱动桥壳、主减速器和差速器等各项参数的确定，其中包括主要参数的选择计算、受力情况、强度校核等，并且还对一对齿轮上的支承轴承进行了寿命校核。以及对本次设计做出总结。整个毕业设计历时两个多月，在老师的悉心指导和同学的热心帮助下得以顺利完成。最后感谢在毕业设计期间给予我帮助的老师和同学。从这次毕业设计中，我必将受益非浅。

Abstract  

The second-row seat designed for passenger car drive axle housing to carry out, . The purpose was to test the University of years of learning outcomesAs well as future work to lay a solid foundation for work. Set forth in the specification prepared by the drive axle housing function、The design requirements and its working principle, Through access to a large number of automotive design information, As well as the combination of learned knowledge, Of the drive axle housing program carried out feasibility studies, Structural analysis and design and calculation programs. The design of the drive axle with semi-floating axle as a whole Bridge Shell Single-stage spiral bevel gear. General symmetric cone planetary gear (2) in differential form. Design, including the drive axle housing, The parameters of the main reduction gear and differential determination of Including the main parameters of the choice of calculation, Force situation, Intensity calibration, etc. And also to the two pairs of gears on the supporting bearings of the life of checking. In the final, to sum up this design. Lasted for more than two months the whole graduation project, the teachers of your instructors and fellow students enthusiastic assistance has been completed smoothly. Finally thank for giving me during the graduation project to help teachers and students. Graduation from this design, I will greatly benefit from.
