A wheel including a rim that rotates on a shaft defining a primary rotational axis and a magnetic braking device. The magnetic braking device includes an actuator which includes a first transmission assembly and one second transmission assembly each includes a pinion mounted on the support to pivot about a secondary rotational axis parallel to the primary axis, an operating bar extending about the secondary axis, a first mechanical connecting member connecting the operating bar to the pinion of the transmission assembly and a second mechanical connecting member connecting the operating bar to one of the stators, and the mechanical connecting members are arranged. The rotation of the pinions causes a movement of the stators parallel to the secondary axis in opposite directions, for varying the air gap, one or more of the mechanical connecting members of each transmission assembly being arranged to ensure a screw-nut helical connection.

Wheel with eddy current magnetic braking device and aircraft landing gear provided with such a wheel

A ground movement system for a land transport vehicle () capable of levitating, the vehicle having a plurality of wheels including at least one actuated wheel (), a drive device () for driving the actuated wheel and/or a brake () for braking the actuated wheel (), a vertical positioning actuator () arranged to move the actuated wheel () vertically relative to a fuselage of the vehicle (), and control means arranged to act, during an acceleration stage and/or during a braking stage of the vehicle, to control the vertical positioning actuator () as to adjust the vertical position of the actuated wheel in order to increase the load carried by the actuated wheel and thus increase the maximum force that can be transmitted to the ground by the actuated wheel so as to increase the maximum drive and/or braking torque that can be produced by the drive device () and/or by the brake () without the actuated wheel () skidding or slipping.
