Planetary gears are applied in a wide range of applications. For example power supply of airplane auxiliaries or hybrid electric vehicles benefit from suchlike gears. Thus heavy truck hybrid propulsion based on epicyclic four-speed gears guarantees internal combustion engine optimal working point. Assuming that generic power split modelling for this gear type marks a research focus for some time already. The Bond Graph method as a member of a very closely related power flow modelling tool family is especially very well suitable to meet this aim. The paper argues this message not via common analysis but via synthesis, introduces folding operation as natural effective means for getting vectorial models, shows variants and illustrates generalization via simulation results and numerical examples. Synthesis approach suggested can also serve as a starting point for generation of more detailed models or research and comparison of new epicyclic gear constructions.
