Claims
- 1. A method of improving the drive of a vehicle travelling on steel support and guide rails, said method comprising increasing the adhesive load of the vehicle on the rails, to correspondingly permit increase of the tractive and braking forces, by generating traveling magnetic fields in the rails by a system of linear inductors in elongated array along the rails and so arranged as to have lines of force which lie in planes perpendicular to the direction of travel of the magnetic field and pass transversely through the rails.
- 2. A method as claimed in claim 1 wherein each said rail is utilized as the secondary of an induction motor including linear inductors which serve as the primary, said motor contributing directly to the tractive force or the braking force of said vehicle.
- 3. Electrical induction apparatus for use on a vehicle travelling on steel support and guide rails, said apparatus comprising primary inductors for generating linear magnetic travelling fields along the rails to increase the adhesive load of the vehicle on the rails, said inductors being arranged in an elongate array along the length of the rails and including a plurality of pairs of poles adjacent the rails, said rails constituting a secondary, said poles forming two conjugate sequences along the rails, and means cooperating with said inductors and poles for generating lines of force which lie in planes perpendicular to the direction of travel of the magnetic field and pass through said rails transversely of the direction of travel of the moving fields.
- 4. Apparatus as claimed in claim 3 wherein said poles and inductors are arranged so that said fields contribute directly to the tractive force or the braking force of said vehicles.
- 5. Apparatus as claimed in claim 3 wherein said poles have pole faces parallel to one another and parallel to the upper surface of the rail in spaced location thereabove.
- 6. Apparatus as claimed in claim 3 wherein said poles have pole faces which are perpendicular to one another and define perpendicularly disposed gaps with the rails.
- 7. Apparatus as claimed in claim 3 comprising at least one bogie-truck for said vehicle, comprising spaced axles with at least one wheel mounted on each said axle, axle bearings and a frame mounted between said axles and supported on said axle-bearings, said truck also comprising means for mounting said inductors on said frame to extend longitudinally between said axles.
- 8. Apparatus as claimed in claim 7 wherein said frame also comprises one pivotal connection or articulation between the front and rear end thereof, to provide a non-rigid wheel-base to the associated axles.
- 9. Apparatus as claimed in claim 8 wherein there are included a plurality of said frames to form an articulated motor-platform.
- 10. Apparatus as claimed in claim 9 comprising a multiplebody vehicle mounted on said platform.
- 11. Apparatus as claimed in claim 7 comprising resilient pads on the axle-bearings and means mounting the frame on said pads.
- 12. Apparatus as claimed in claim 9 wherein said vehicle is mounted on said bogie-trucks.
- 13. Electrical linear apparatus for use on a vehicle travelling on at least one electrically conductive rail, said apparatus comprising both a primary inductor with poles for generating magnetic fields along said rail, said rail constituting a secondary and, injector means in pre-determined relative positions with respect to said poles, and control means for supplying said injector means and thereby said rail with electric currents which cooperate with said magnetic fields to produce longitudinal and transverse forces relative to said rail.
- 14. Apparatus as claimed in claim 13 wherein said vehicle includes a prime mover and an electric generator driven by said prime mover for supplying electrical power to said apparatus.
- 15. Apparatus as claimed in claim 13 wherein said vehicle includes collector means for transmitting electrical power from an external source to said control means and therefrom to said inductor and injector means.
- 16. Apparatus as claimed in claim 13 comprising means for shifting said injector means relative to said poles.
- 17. Apparatus as claimed in claim 13 comprising means for raising and lowering said injector means into contact with said rail.
- 18. Apparatus as claimed in claim 13 wherein said vehicle travels on two electrically conductive rails.
- 19. Apparatus as claimed in claim 8 comprising at least one bogie-truck for said vehicle and means mounting said apparatus on said truck to face said rails longitudinally.
- 20. Apparatus as claimed in claim 19 wherein said truck comprises spaced axles and means to provide a non-rigid wheel-base to said axles.
- 21. Apparatus as claimed in claim 20 wherein there are included a plurality of said trucks to form an articulated motorplatform.
- 22. Apparatus as claimed in claim 21 comprising a multiplebody vehicle mounted on said platform.
- 23. Apparatus as claimed in claim 19 wherein said vehicle is mounted on said bogie-trucks.
