To provide a power train system of a hybrid vehicle which has a short entire length, which enables an effective arrangement in an engine room, and which can easily adjust the transmission of power of an engine and a motor.
The power train system of the hybrid vehicle includes a first shaft, a second shaft, a third shaft, and a fourth shaft. The first shaft is provided with the engine, a generator, and the motor, and a planetary gear set is attached between the generator and the motor. Then the second shaft is provided with a second-shaft driven gear and a second-shaft drive gear. The second-shaft driven gear is connected to the first shaft so that it receives the transmission of power from the planetary gear set of the first shaft, and the second-shaft drive gear is axially connected to the second-shaft driven gear and rotates. Then the third shaft is provided with a third-shaft driven gear and a third-shaft drive gear. The third-shaft driven gear is connected to the second shaft so that it receives the transmission of power from the second-shaft drive gear, and the third-shaft drive gear is axially connected to the third-shaft driven gear and rotates. Then the fourth shaft is provided with a differential ring gear and a differential device, and the differential ring gear is engaged with the third-shaft drive gear, and is connected to the third shaft.
