  • Planetary power take off device
    Patent number: 8864619
    Abstract: A power take off device includes input and output shafts and an integral planetary gear set. The power take off device may be a single speed or a two speed device. The input shaft and the output shaft are mechanically connected through the planetary gear set. In one mode of operation of the power take off device, a substantial speed reduction and torque increase is provided between the input shaft and the output shaft. The power take off device may change to a second mode of operation without stopping to provide a direct one to one speed and torque ratio between the input shaft and the output shaft. A planetary gear set clutch unit includes a two direction actuator that provides fluid pressure actuation and release of the clutch unit with a single input signal.
