Abstract: The invention relates to a device for coupling together two elements mounted to rotate about a common axis of rotation (X) in order to enable one of the elements to be selectively driven in rotation by the other, the device comprising two members (3, 4), each secured to a respective one of the elements for coupling together, the elements being axially movable relative to each other between a remote position in which the members do not co-operate and the elements are decoupled, and an engaged position in which the members co-operate with each other in order to provide a rotary connection between the two elements. According to the invention, one of the members forms a plate (3) having a face (P) perpendicular to the axis of rotation and in which a plurality of housings (15) are formed, the housings extending in radial directions; the other one of the elements carrying rollers (23) that are mounted to rotate about radial axes to project from said element so that each of them can penetrate into any one of the housings when the members are engaged and can co-operate with the side faces (14) of the housing in order to provide a rotary connection between the two members.

Abstract: A device, which connects a gearmotor to an aircraft wheel, comprising: a casing rotatably carrying a shaft driven by the gearmotor, the shaft having a fluted portion on which a gearwheel is mounted to slide along a longitudinal axis of the shaft without rotating relative to the shaft; a toothed ring for constraining to rotate with the aircraft wheel; and means for moving the gearwheel axially between a retracted position (disengaged from the toothed ring) and an engaged position (gearwheel meshes with the toothed ring). The means for moving comprises a hollow screw-and-nut assembly extending around the shaft, one of the elements being axially secured to the gearwheel but prevented from rotating by an anti-rotation member, and the other element of the screw-and-nut assembly being rotatably mounted inside the casing to be driven selectively by an electric motor so that rotating the electric motor causes the gearwheel to move axially.
