ABSTRACT:
An orientable axle with independent wheels comprises a beam perpendicular the axis of the wheels. It also comprises sensors (16, 20) for measuring the position of the beam with respect to the track; a reference position with respect to the track is predetermined. Electromagnets (22) carried by the axle cooperate with the track for exerting on the axle a force for orientating it. A control circuit delivers a current to the electromagnets for moving the axle in an angular direction which tends to cancel out the difference between the measured position and the reference position. The axle can be used on railroad vehicles having to negociate curves at high speeds.
