A wheel drive system for ground movement of an aircraft includes a motor system and a clutch system. The motor system, which is borne by an unsuspended part of a landing gear strut of the aircraft, includes an electric motor and a reduction gearing system. The clutch system, which connects an output shaft of the electric motor to a wheel of the aircraft via the reduction gearing system, includes a dog-clutch and a translational movement system. The dog-clutch includes a drive part, which is secured to the motor system, and a receiving part, which secures to a rim of the wheel. The translational movement system moves the drive part along an axis of an axle crossbeam of the landing gear strut into an engaged position, in which the drive part collaborates with the receiving part, and a disengaged position, in which the drive part is separated from the receiving part.

Wheel drive system, in particular for an aircraft

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.

An electrical assist device is provided for a bicycle. The device includes an electric machine, a drive pinion, an attachment device, a source of electrical energy, and a controller. The attachment device fixes the electric machine to the bicycle near a tire of a wheel of the bicycle. The source of electrical energy powers the electric machine. The controller controls the electric machine. The electric machine includes a rotor, which drives the drive pinion. The drive pinion includes teeth structured to mesh tangentially with complementary teeth fastened to the tire.

A motorizing system is provided for powering a wheel associated with a suspension of an aircraft, so that the aircraft can be moved around on ground. The motorized system includes a motor unit, a drive member that is structured to be secured to the wheel, and a clutch device that connects an output shaft of the motor unit to the drive member. The motor unit is structured to be secured to a sprung part of a suspension strut. A positive transmission occurs between the motor unit and the drive member.

System for motorizing a wheel connected to a suspension

The invention relates to a system for motorizing a wheel (), the system comprising a motor unit (), a drive member () secured to the wheel () and a clutch device () connects the output shaft () of the motor unit () to the drive member ().
