Abstract
A power take-off for an electric vehicle. The power take-off includes a variable speed electric motor for driving at least one wheel of the vehicle. A transmission, including a neutral state, coupled to the electric motor. An auxiliary output shaft is coupled to the transmission. When the transmission is in the neutral state, the auxiliary output shaft will operate at a speed independent of wheel speed and dependent on the electric motor speed. When the transmission is operably engaged in other than the neutral state, the auxiliary output shaft will operate at a speed related to both the electric motor speed and the wheel speed.
