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, ma
