An aircraft landing gear including a wheel rotatable about an axle, a motor, and a bi-directional overrunning clutch, such as a roller or sprag clutch, operable to either connect the wheel with the motor or disconnect the wheel from the motor. The bi-directional clutch includes a ring-shaped overrunning track connected to the wheel by a plurality of drive keys, a ring-shaped drive track connected to the motor and concentrically aligned with the overrunning track, and a plurality of movable elements, each separately and individually movable, retained between the overrunning track and the drive track.

An aircraft landing gear including a wheel rotatable about an axle, a motor, and a bi-directional overrunning clutch, such as a roller or sprag clutch, operable to either connect the wheel with the motor or disconnect the wheel from the motor. The bi-directional clutch includes a ring-shaped overrunning track connected to the wheel, a ring-shaped drive track connected to the motor and concentrically aligned with the overrunning track, and a plurality of movable elements retained between the overrunning track and the drive track. The movable elements are movable between: a driven configuration in which they prevent relative rotation between the drive track and the overrunning track to thereby permit the wheel to be driven by the motor; and an overrunning configuration in which they permit relative rotation between the drive track and the overrunning track to thereby disconnect the wheel from the motor.
