Abstract: The invention relates to a device for driving rotation of an aircraft wheel comprising a rim (4) mounted to rotate on an axle (2) of landing gear about an axis of rotation (X), the device comprising a drive ring gear (103) and a drive actuator (101) having an outlet pinion (102) that co-operates with the drive ring gear to drive the wheel in rotation. The drive ring gear is mounted to rotate about the axis of the rim of the wheel, the drive device including selective coupling means (150) that are operable to link the rim and the drive ring gears together in rotation, or to disconnect them.

Abstract: An assembly for rotationally friction driving the wheel of an airplane provided with a driving track. The assembly has a base intended to be fixed to a lower part of the landing gear, two arms mounted to pivot on the base, and rollers so mounted as to rotate at the end of each arm, with each roller being associated with a pinion for rotationally driving the roller. A central pinion is mounted so as to rotate along the arms pivot axis so that the rollers driving pinions engage with the central pinion. A drive actuator acts on the arms of the assembly so as to position the assembly either in a disengaged position in which the rollers are separated from the driving track, or in an engaged position in which the rollers are held to rest on the driving track.
