Magnetic suspension railway

Abstract

A magnetic suspension for a railway vehicle with electromagnetic carrying, guiding and driving gear, wherein the forces of the exciter and transverse flux magnets support, guide, drive and brake together with an active motor section by regulating the gap distance from a track-side reaction rail measured by gap, measured by gap sensors, and wherein the vehicle includes hover frames and the magnets are resiliently mounted to the hover frames in such a way that both supporting and guiding magnets as well as the carrying magnets of the two longsides of the vehicles are separated from each other as to action and the hover frames are coupled to the vehicle superstructure through spring means is disclosed. Each magnet includes at least four coils and the transvers flux magnets have adjacent coils with coil lengths selected so that within the magnet coil peripheries of the adjacent coils, lying side by side, do not coincide. The coils of the magnets are divided into two identical groups and the coils of each group are distributed over the total length of the magnets so as to supply the torques required for stabilization of the pitch movement of the vehicle. The coils of each group are operable responsive to an autonomous gap control loop. The supporting and guiding magnets have glide skids for limiting the free motion play in the vertical and horizontal directions relative to the track to a predetermined gap deviation to be expected in service.
