Abstract: A method of applying rotary drive by friction to an aircraft wheel that is provided with a drive track and that is mounted to rotate about an axis of rotation (X) on an axle carried by a low portion of aircraft landing gear by means of at least one friction roller (21) driven by a drive actuator (11) and associated with an actuator (23A, 23B, 30) for moving the roller between a disengaged position in which the roller is spaced apart from the drive track of the wheel and an engaged position in which the roller is kept pressed against the drive track. The method includes the step of controlling the force delivered by the actuator while they are holding the roller in the engaged position.

Abstract: Drive equipment for rotating by friction an aircraft wheel equipped with a drive track and mounted to turn about an axis (X) on an axle of an aircraft undercarriage. The equipment comprise a base (22), a slide (24) mounted on the base on a sliding axis extending in a radial direction (R1, R1), a support (26) pivotable on the slide on an axis parallel to the rotation axis of the wheel; two rollers (21) rotatable on rotation axes parallel to the pivot axis; a central shaft (28) mounted for rotation on the support and being in engagement with the two rollers to provide their rotation; and an actuator (23A, 23B, 30) for moving the slide and the support between a disengagement position with the rollers distant from the wheel drive track and an engagement position with the rollers are held in contact with the drive track of the wheel.

Abstract: An undercarriage comprising at least: a wheel mounted on an axle (3); a brake comprising a torsion tube (9), friction members (11) mounted around the torsion tube, and at least one brake actuator (13) for selectively exerting a braking force on the friction members; and drive means for driving rotation of the wheel and comprising an electric motor (14) that is connected to a rim (5) of the wheel (4) by a coupler member (15). The coupler member extends at least in part around the axle (3) between the axle and the torsion tube (9) of the brake.
