US Patent 9751622 Wheel motorizing system, notably for an aircraft wheel

A wheel motorization system, useable for an aircraft to run along a ground surface, includes an electric motor, a driving member securable with a hub of a wheel of the aircraft, and a clutch device connecting an output shaft of the motor to the driving member via a reduction device. The clutch device includes a freewheel device, which allows transmission of a rotational torque only in a first torque transmission direction when the aircraft is travelling forwards.
