1. A wheel comprising a rim mounted to rotate on a support comprising:
a shaft defining a primary rotational axis, and
an eddy current magnetic braking device comprising at least one first braking set comprising a first stator and a second stator which are connected to the support and a rotor connected to the rim and disposed between the stators, such that each stator has a first face opposite a face of the rotor and separated from said face by an air gap, the rotor being made of electrically conductive material and the stators carrying a plurality of magnets emitting via the first face, a magnetic flux capable of causing, in accordance with the air gap, eddy currents in the rotor when the rotor pivots with the wheel,
wherein the eddy current magnetic braking device comprising comprises an actuator which comprises at least one first transmission assembly and one second transmission assembly each comprising 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 in question and at least one second mechanical connecting member connecting the operating bar to one of the stators; and in that the mechanical connecting members are arranged, such that the rotation of the pinions causes a movement of the stators parallel to the secondary axis in opposite directions, for varying the air gap, at least one of the mechanical connecting members of each transmission assembly being arranged to ensure a screw-nut helical connection.
