Discussed the automobile transmission gearbox classified situation, elaborated the domestic and foreign automobile transmission gearbox research present situation. Specifically explained the automobile mechanical type transmission gearbox design procedure and this topic design situation. In the article has indicated this transmission gearbox power drive plan, and the computation enumerated the correlation to keep off position the velocity ratio, has designed the transmission gearbox transmission gear, the axis and so on the important spare part. This article uses UG software to carry on the automobile mechanical type organic transmission gearbox always to become the design, and has the important components design and the manufacture process. Spare part and transmission gearbox whole assembly manufacture process, as well as transmission gearbox movement simulation process, two-dimensional engineering plat production. Finite element analysis process. [Key words]: gearbox ＵＧ modeling assembling Sport analysis1.绪论 1 1.1 CAD软件在国内外发展现状及研究意义 1 1.2设计开发平台的选取 1 1.3 Unigraphics软件的简介 2 1.4 商用车变速器在国内发展现状 2 1.5 机械式商用汽车变
