<p>An electromagnetic suspension system for a vehicle has an electromagnet with an upright portion having a lift magnetising winding and outwardly-extending arms at the top and bottom of this upright portion. Pole pieces on the four arms co-operate with reaction rails having corresponding surfaces. The vehicle can operate with a left-hand or a right-hand reaction rail or with both rails, thereby enabling gaps to be provided in rails at track junctions. Lateral guidance windings are provided on the lower arms of the magnet and the lower pole faces slope to the horizontal, in the lateral direction of the track so that, at a track junction, by energising appropriate windings, the vehicle is guided to a selected track. The lower arms are longer than the upper arms to give, as a result of the leakage flux, lateral damping.</p> |
