This paper puts forward the method of obtaining new types of RV transmission. Research shows that the topological graph can effectively express the topology unit and topological structure of RV transmission; the process that through topology degradation and evolutionary method to Obtain the RV transmission of topology map and through the topology inversion to get the new organization is practical and feasible. The topological evolution methods have tie bar evolution, tree, increasing gear tooth ring and mixing superimposed evolution. The RV transmission topology inversion is implemented by the way of gear ring, Gear meshing, the gear, the shaft, tie rod and the frame. Method was developed to get the evolutions of a variety of RV transmission, and the evolution of a graph of the inverse mapping was enumerated. The topology graph theory methods used in the RV transmission for the structure of RV transmission innovation provides an important theoretical method.
