Abstract

Due to the complexity of the planetary gear train (PGT), it is difficult to design novel configurations of power-split hybrid transmission with three planetary gear sets (PGSs) containing input-split and compound-split two modes. One of the effective solutions is to complete configuration synthesis and establish a complete database of configurations to assist in the design. For this reason, a uniform and simple digital code is proposed to represent the two-mode power-split hybrid transmission configuration, which divides the configuration into PGT and shift element (SE) two parts. The computer only needs to read the digital code to automatically complete the mode analysis, motion characteristics analysis and mechanical interference detection, which are the basis for the configuration synthesis. In addition, to improve design efficiency, while completing the configuration synthesis, the structure and motion characteristics of each configuration are stored in MySQL database, which realizes the fast reading of configuration information. Through this method of assisting configuration design, engineers can quickly search for feasible configurations according to the requirements. Therefore, this method is instructive for the design of power-split hybrid transmission configuration.
