摘要： An apparatus for transferring power includes a shaft, a pair of pawls, and an outer member. The shaft has a first end which is connected to an electric motor and a second end which is operatively associated with the pawls. As the shaft turns, the pawls are forced outwardly against a non-circular interior surface of the outer member. As the pawls contact the inner surface of the outer member, they transfer rotational energy from the rotating shaft to the outer member, causing it to also rotate. When power to the electric motor is shut off, the shaft stops turning. The pawls are spring biased inwardly toward the shaft. When the shaft stops turning, the pawls move inwardly toward the shaft and are not connected any longer to the interior surface of the outer member. The outer member is free to spin freely even though the motor is stopped.
