Systematic Design Scheme of Active Transmission Based on Fixed axle Gear Sets

Abstract:

A systematic design process for the electrified manual transmission(eMT) is proposed on the basis of a morphological analysis. First, the independent design parameters, its feasibility constraints and consistency conditions need to be defined by analyzing the structure and functions of eMT. According to these boundary conditions, structure variables such as the number of components and the connection type can be solved to synthesize the component types. Then, the scheme number of each structure type is synthesized. After the abstraction from practical mechanism to topology model, the corresponding matrix is attained. All transmission paths can be gained by the analysis of the matrix. Based on the paths, the schemes concerning component layout and operating mode can be gained. Finally, all transmission schemes meeting the structural and functional requirements are synthesized.
