Abstract Power-split transmission system was very complex in structure; the continuously variable transmitting performance of this system is difficult to analysis, which impeded the further research of this kind of transmission. In this research, universal series mathematical models of power-split transmission system were set up firstly. Then, the lever analogy analysis method was introduced into the power-split transmission performance analysis process, and the multi-range continuously variable transmitting performance of power-split transmission was described comprehensive. Finally, the method was used to analysis one real power-split transmission systems, ZF Friedrichshafen power, and the accuracy, validity and convenience of this method were verified. The result show that the method of mathematical model combine with lever analogy could analysis the power-split transmission system continuously variable transmitting performance more correctly, easily and rapidly, it could provide a more intuitive and efficiently analysis method for the further research of power-split transmission system.
