  • Transaxle unit for hybrid vehicle
    Patent number: 9309933
    Abstract: A transaxle unit that separately transmits power from an engine and power from a motor to an output shaft of driving wheels and transmits the power from the engine to a generator is provided. A rotary shaft of the motor is disposed vertically apart from the output shaft, and a rotary shaft of the generator is disposed horizontally apart from the output shaft. A clutch is disposed in the transaxle unit in a power transmission path from the engine to the output shaft to connect or disconnect the power from the engine. A pump is disposed coaxially with a rotary shaft of the clutch on a side of the transaxle unit to generate hydraulic pressure for the clutch with the power from the output shaft.
