Abstract
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.

A wheel motorization system useable for an aircraft to run along a ground surface, the system comprising:
- an electric motor;
- a driver securable to a hub of a wheel of the aircraft;
- and
- a clutch connecting an output shaft of the motor to the driver via a reducer,
- wherein the clutch includes a freewheel structured to allow transmission of a rotational torque only in a first torque transmission direction when the aircraft is travelling forwards,
- wherein the freewheel includes non-return elements mounted between an inner ring and an outer ring of the clutch, and
- wherein the clutch includes a lock that locks a freewheeling function of the freewheel, the lock including:
- a locking bell that is coaxial with an axis of the freewheel,
- peripheral driving claws extending from a periphery of the locking bell, the peripheral driving claws being structured to cooperate with the outer ring, and
- central driving claws positioned at a central region of the locking bell, the central driving claws being structured to cooperate with the inner ring.
An aircraft comprising at least one motorized wheel, wherein each motorized wheel includes:
- a wheel;
- and
- a wheel motorization system that includes:
- an electric motor,
- a driver securable to a hub of the wheel, and
- a clutch connecting an output shaft of the motor to the driver via a reducer,
- wherein the clutch includes a freewheel structured to allow transmission of a rotational torque only in a first torque transmission direction when the aircraft is travelling forwards,
- wherein the freewheel includes non-return elements mounted between an inner ring and an outer ring of the clutch, and
- wherein the clutch includes a lock that locks a freewheeling function of the freewheel, the lock including:
- a locking bell that is coaxial with an axis of the freewheel,
- peripheral driving claws extending from a periphery of the locking bell, the peripheral driving claws being structured to cooperate with the outer ring, and
- central driving claws positioned at a central region of the locking bell, the central driving claws being structured to cooperate with the inner ring.
