Abstract
Wheel drive system, particularly for the ground circulation of an aircraft comprising a motor unit (22) borne by an unsuspended part (14b) of a landing gear strut (14) of the aircraft and comprising an electric motor (26) and reduction means, and a clutch device (24) connecting the output shaft (26a) of the electric motor (26) to the wheel (12) via the reduction means.
The clutch device (24) comprises a dog-clutch mechanism (32, 34) comprising a drive part (32) secured to the motor unit (22) and a receiving part (34) secured to the tire (12a) of the wheel (12), and a system for the translational movement, along the axis of the axle crossbeam (20) of the landing gear strut (14), of the drive part (32) into an engaged position in which the drive part (32) collaborates with the receiving part (34) and a disengaged position in which the drive part (32) is separated from the receiving part (34).

16. A wheel drive system for ground movement of an aircraft, the wheel drive system comprising:
-
a motor system supported by an unsuspended part of a landing gear strut of the aircraft, the motor system including; an electric motor, and a reduction gearing system; and a clutch system, which connects an output shaft of the electric motor to a wheel of the aircraft via the reduction gearing system, the clutch system including; a dog-clutch including a drive part, which is secured to the motor system, and a receiving part, which secures to a tire of the wheel, and a translational movement system, which translationally 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, wherein the receiving part includes a plurality of shock-absorbing pads that project axially towards the drive part and that are spaced apart so as to leave a square-edged slot between each adjacent pair of the shock-absorbing pads. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. An aircraft comprising:
-
a wheel; a landing gear strut; and a wheel drive system for ground movement of the aircraft, the wheel drive system including; a motor system supported by an unsuspended part of the landing gear strut, the motor system including; an electric motor, and a reduction gearing system, and a clutch system, which connects an output shaft of the electric motor to the wheel via the reduction gearing system, the clutch system including; a dog-clutch including a drive part, which is secured to the motor system, and a receiving part, which secures to a tire of the wheel, and a translational movement system, which translationally 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, wherein the receiving part includes a plurality of shock-absorbing pads that project axially towards the drive part and that are spaced apart so as to leave a square-edged slot between each adjacent pair of the shock-absorbing pads. - View Dependent Claims (31)
