摘要
微型车在汽车市场的占有率都很大。在我国,2006年汽车保有量约3880万辆,其中微型车比重已经达到31.65%。变速器操纵机构是汽车不可分割的一部分,它的设计不容忽视,因而它的模拟装配技术也就相当重要。操纵机构是变速器的重要部分,它由换挡壳体、换挡摇臂总成、拨叉、拨叉轴总成等零件组成。本次设计是应用Pro/E软件对变速器操纵机构的零件及后壳体进行三维绘制,并且对变速器操纵机构进行模拟装配。
Pro/E软件能为技术开发缩短周期,对提高产品制造水平有很大的帮助,通过运用Pro/E软件虚拟装配作为虚拟制造实施的核心技术,进行变速器操纵机构的模拟装配,从而达到对变速器操纵机构的装配工艺进一步更深了解;这样可以从本质上提高制造效率,节省劳动力,节约生产资源;加快了解汽车企业生产工艺设计、制造及应用的过程,该毕业设计可以加强国内外流行三维Pro/E软件的使用与掌握。

ABSTRACT
The rate of micro-car in motorcar market are great.The number of vehicle in China at 2006 are about 38.8 million, of which the proportion of micro-car has reached 31.65 percent. Derailleur is an inalienable part and its design can not be ignored, thus so as its simulate assemble. Manipulation of institutions is an important part of derailleur ,Which are made from Shell, shifting rocker assemble, fork, fork shaft assemble, and other component parts. The design is the application of Pro / E software for derailleur and manipulation of body parts and the shell 3D rendering, manipulation and transmission of the bodies to simulate assemble.
Pro / E software is helpful to shorten the cycle for technology development and to enhance the level of product manufacturing, through the use of Pro / E software virtual assemble as a virtual manufacturing implementation of the core technology for manipulating the analog transmission assemble, to achieve the transmission control. The assemble process to a better understand can improve manufacturing efficiency, labour-saving, the saving of production resources at nature; and it accelerate the understanding of car production process design, manufacture and application of the process, the graduate design can enhance the use and control the popular 3D Pro / E software at home and abroad.
