Abstract
In a magnetic suspension railroad where a suspension vehicle is guided by magnetic forces between a magnet on the vehicle and magnetic fields generated in track coils comprising opposing coil halves, switching contacts are arranged in the coils such that the switching contacts of the desired travel path are closed and the switching contacts of the coils of the other travel path are open.
Claims4
In a magnetic suspension railroad in which a magnetic suspension vehicle is guided by means of magnetic forces between a magnet installed in the vehicle and reaction means arranged on the track, means for setting the direction of the vehicle at a switch comprising:
- a. a guidance coil located centrally on the vehicle;
- b. a first plurality of conductor loops arranged for cooperation with said centrally located guidance coil following the straight path of travel;
- c. a second plurality of conductor loops arranged for cooperation with said centrally located guidance coil for following a branch path;
- and
- d. at least one disconnect switch associated with said first and second plurality of conductor loops for selectively closing one plurality of loops and opening the other plurality of loops whereby the vehicle will follow the path containing the closed loops said loops when closed being closed on themselves whereby the only currents flowing in said loops will be currents induced by said guidance coil on said vehicle.
