ABSTRACT
　　　The cycloidal-pin wheel drive unit is one of the most important transmission components of the mechanism by its smaller volume，lighter weight and effective transmission. This paper takes the urban railway vehicle drive unit as the research subject and investigates its parameter selection and the general design method of the modeling and motion simulation in Pro/E systematically. The main research content as follows:
　　　On the basic of the comprehensive analysis and comparison of all kind of Planetary reducer transmission, the transmission principle of the cycloidal-pin wheel drive unit is researched, the cycloid contour line equation and the rules of the designing parameter selection of the cycloid contour line is established.
　　　With the cycloidal-pin wheel drive unit as an example, the 3D entity model and assembly is performed with the application of Pro/E, the parameter design method of Cycloid in Pro/E and the general rules of virtual assembly of the cycloidal-pin wheel drive unit are main researched. In order to prove the rationality of the parameter design of the cycloidal-pin wheel drive unit, the simulation movement of the unit is performed.
　　　The research has certain directive significance to carry out the parameter design of the urban railway vehicle drive unit.

Key Words：Cycloid transmission; Cycloid; modeling; Motion simulation
