DEVICE TO SELECTIVELY CONNECT A MOTOR REDUCER TO AN AIRCRAFT WHEEL TO ALLOW WHEEL TO BE SELECTIVELY DRIVEN BY THE MOTOR REDUCER

摘要

DEVICE FOR SELECTIVELY CONNECTING A MOTOR-REDUCER TO AN AIRCRAFT WHEEL TO ALLOW THE WHEEL TO BE SELECTIVELY ACTIVATED BY THE MOTOR-REDUCER. The invention relates to a device for connecting a gearmotor to an aircraft wheel, the device comprising: - a box rotatingly carrying an axle (4) which must be driven by the gearmotor, the axle having a grooved portion (7 ) in which a gear wheel (8) is mounted to slide along a longitudinal axis of the axis (4) without rotation relative to the axis; - a toothed ring (9) to force the aircraft wheel to rotate; and - means for moving the toothed wheel (8) axially between a retracted position where it is disengaged from the toothed ring (9) and a engaged position where the toothed wheel (8) engages with the toothed ring (9). According to the invention, the means for moving the sprocket (8) axially comprise a hollow bolt and nut assembly (11,13) extending around the shaft (4), one of the elements of the bolt and nut assembly being axially fixed to the sprocket, but prevented from turning by an anti-rotation member, and the other element of the bolt and nut assembly being rotatably mounted inside the box (1) to be selectively driven by an electric motor (20) so that rotation of the electric motor (20) causes the sprocket (8) to move axially.
