Ground movement system of a land transport vehicle liable to levitate

摘要

System for moving a levitating land transport vehicle on the ground (2), comprising a plurality of wheels comprising at least one actuated wheel (3), a drive device (6) for the actuated wheel and / or a brake (8) of the actuated wheel (3), a vertical positioning actuator (9) arranged to vertically move the actuated wheel (3) relative to a fuselage of the vehicle (2), and control means arranged for, at during an acceleration phase and / or during a vehicle braking phase, pilot the vertical positioning actuator (9) so as to adjust a vertical position of the actuated wheel to increase a load resting on the actuated wheel and therefore to increase a maximum force transmissible to the ground by the actuated wheel, so as to increase a maximum drive and / or braking torque which can be produced by the drive device (6) and / or by the brake (8) without the actuated wheel (3) slipping or does not slip.
