差速器的设计

摘要

本次毕业设计主要是6401旅行车对安装在驱动桥的两个半轴之间的差速器进行设计，主要涉及到了差速器非标准零件如齿轮结构和标准零件的设计计算，同时也介绍了差速器的发展现状和差速器的种类，对于差速器的方案选择和工作原理也作出了简略的说明。在设计中参考了大量的文献，因此对差速器的结构和作用有了更透彻的了解，通过利用Auto cad软件对差速器进行绘图工作，也让我在学习方面得到了提高。在去年金融危机的影响下，汽车产业结构的重组给汽车的发展带来了新的机遇，与汽车相关的各行各业更加注重汽车的质量。差速器作为汽车必不可少的组成部分之一也在汽车市场上产生了激烈的竞争。此次就是针对汽车差速器这一零件进行设计的,再设计出合理适用的差速器的同时也对差速器相关的行业有了一定得认识。通过绘制差速器的组件图也让我在学习方面得到了提高。

Abstract

In the last year under the impact of financial crisis, automotive industrial restructuring brought about by the development of motor vehicles to new opportunities, and automotive related businesses pay more attention to the quality of cars.Differential as an integral part of car, one of the automotive market also resulted in fierce competition.The differential is the spare parts for motor vehicles designed.The design of the main drivers on the installation of the bridge in between the two axle differential design, mainly related to the differential struct -ure of non-standard parts such as gear parts and standards for design and calculation, but also introduced the development of differential status and the type of differential.For differential selection and the principle of the program have also made a brief note. Reference in the desi -gn of a large amount of literature on the role of differential structure and have a more thoro -ugh understanding. Re-engineering the application of a reasonable differential at the same time also has been related industries must be aware of. Differential through the mapping component map also let me in the field of learning has been improved.

Keywords: Axle, differential, gear structure
