摘 要
微型汽车在我国有很大市场，从0.9L到1.6L，价格适合我国国情，适合正在发展的中国的现况。变速器作为传动系统的重要部件之一, 其操纵机构更是车辆操纵中最频繁的装置，因此变速器操纵机构的装配质量和效率直接关系到变速器本身乃至整车性能发挥和制造质量的好坏。针对这一问题，虚拟样机技术的成功应用不仅可以提高装配精度，而且可以缩短产品设计周期，对于工程实际具有重要的应用价值。本设计通过运用Pro/E软件，在Pro/ENGINEER参数化建模的基础上，对变速器操纵机构各零部件进行实体建模，虚拟其装配过程，并实现汽车变速器操纵机构的动态仿真。从而对变速器操纵机构的装配进一步了解；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设计、制造及应用的过程。

ABSTRACT
Mini car market in China has greatly market, from 0.9L to 1.6L, the price is suitable for China's national conditions and the developing China's current situation. As one of the important parts of transmission system, the operation of transmission is the most frequent part in the vehicle handling equipment.So the efficiency and quality of assembly of transmission operation is directly related to the transmission itself and the vehicle performance and whether the manufacturing quality is good or bad.
To solve this problem, the successful application of virtual prototype technology can not only improve the assembly accuracy, but also shorten the product design cycle,which is important for engineering application value. By using the Pro / E software, this design,based on Pro / ENGINEER parametric modeling, modeled the various parts of the transmission control mechanism solidly, virtualed assembling process and realized the transmission control by dynamic simulation in order to make a further understanding of the transmission control assembly. This can essentially improve the manufacturing efficiency,save the labor resources and producting resources and accelerate the understangding about the process of auto enterprise production design, manufacturing and application.
Key words： transmission control mechanism; modeling; simulation; assembly; design
