Abstract

A rail system including a rail-bound vehicle, which is able to be moved along a rail track, the rail track being made up of rail components, in particular, the rail-bound vehicle having an electric motor, with the aid of which the rail-bound vehicle is able to be driven, in particular moved along the rail track in the rail direction, one or more pole wheel piece assembly/assemblies being situated in a stationary manner, i.e., connected to the rail track, the rail-bound vehicle having a reaction part, which is able to be brought into operative connection with the pole wheel piece assembly, in particular for the purpose of generating a reaction force generated by eddy currents.

First claim

The invention claimed is:

1. A rail system, comprising:
a rail track;
a rail-bound vehicle movable along the rail track and including an electric motor, with the aid of which the rail-bound vehicle is able to be driven in a rail direction along the rail track; and
at least one pole wheel piece assembly situated in a stationary manner, connected to the rail track, wherein the rail-bound vehicle includes a reaction part that is able to be brought into operative connection with the pole wheel piece assembly, the pole wheel piece assembly adapted to propel the rail-bound vehicle in a forward direction.

2. The rail system as recited in claim 1 , wherein the rail track includes rail components.

3. The rail system as recited in claim 1 , wherein the rail-bound vehicle has a drive, and cooperates with the rail track, an amount of a feed force maximally able to be generated by the drive being smaller than an amount of a downgrade force occurring in a subregion of the rail track.

4. The rail system as recited in claim 3 , wherein the drive includes one of a gear wheel and friction wheel which is driven by the electric motor one of directly and via a gearing.

5. The rail system as recited in claim 1 , wherein the pole wheel piece assembly is situated along an uphill track section for the purpose of generating an additional feed force for overcoming a downgrade force.

6. The rail system as recited in claim 1 , wherein the reaction part is fixed in place on a linkage of the rail-bound vehicle, and wherein the linkage is able to be maneuvered on one of the rail track and rail sections via wheels supported on the linkage.

7. The rail system according to claim 1 , wherein each pole wheel piece assembly adapted to propel the rail-bound vehicle forward and upwardly in a respective upwardly-sloped section of the rail track.

8. The rail system according to claim 1 , wherein the pole wheel piece assembly is adapted to propel the rail-bound vehicle in the forward direction while the reaction part is in operative connection with the pole wheel piece assembly.

9. A rail system, comprising:
a rail track;
a rail-bound vehicle movable along the rail track and including an electric motor, with the aid of which the rail-bound vehicle is able to be driven in a rail direction along the rail track; and
at least one pole wheel piece assembly situated in a stationary manner, connected to the rail track, wherein the rail-bound vehicle includes a reaction part that is able to be brought into operative connection with the pole wheel piece assembly;
wherein the reaction part is brought into operative connection with the pole wheel assembly for the purpose of producing a reaction force generated by an eddy current.

10. A rail system, comprising:
a rail track;
a rail-bound vehicle movable along the rail track and including an electric motor, with the aid of which the rail-bound vehicle is able to be driven in a rail direction along the rail track; and
at least one pole wheel piece assembly situated in a stationary manner, connected to the rail track, wherein the rail-bound vehicle includes a reaction part that is able to be brought into operative connection with the pole wheel piece assembly;
wherein each pole wheel piece assembly includes pole wheel pieces driven by a second motor, between which at least an individual gap region is situated, through which a section of the reaction part is able to travel.

11. A rail system, comprising:
a rail track;
a rail-bound vehicle movable along the rail track and including an electric motor, with the aid of which the rail-bound vehicle is able to be driven in a rail direction along the rail track; and
at least one pole wheel piece assembly situated in a stationary manner, connected to the rail track, wherein the rail-bound vehicle includes a reaction part that is able to be brought into operative connection with the pole wheel piece assembly;
wherein each pole wheel piece assembly has pole wheel pieces which are driven by a second motor, and wherein a gap region is disposed between two adjacent pole wheel pieces in each case, through which a particular section of the reaction part is able to travel.

12. A rail system, comprising:
a rail track;
a rail-bound vehicle movable along the rail track and including an electric motor, with the aid of which the rail-bound vehicle is able to be driven in a rail direction along the rail track; and
at least one pole wheel piece assembly situated in a stationary manner, connected to the rail track, wherein the rail-bound vehicle includes a reaction part that is able to be brought into operative connection with the pole wheel piece assembly;
wherein the reaction part has leg sections, and wherein each leg section is able to be plunged into a gap region between two pole wheel pieces of an individual pole wheel piece assembly, and be moved through the gap region in a track direction.

13. The rail system as recited in claim 12 , wherein at least one of the leg sections of the reaction part and gap regions between two pole wheel pieces of an individual pole wheel piece assembly are spaced apart from each other at regular intervals.

14. A rail system, comprising:
a rail track;
a rail-bound vehicle movable along the rail track and including an electric motor, with the aid of which the rail-bound vehicle is able to be driven in a rail direction along the rail track; and
at least one pole wheel piece assembly situated in a stationary manner, connected to the rail track, wherein the rail-bound vehicle includes a reaction part that is able to be brought into operative connection with the pole wheel piece assembly;
wherein the at least one pole wheel assembly includes a plurality of pole wheel assemblies, and wherein intervals between the pole wheel piece assemblies following each other in a track direction are smaller than an extension of the reaction part in the track direction.

15. A rail system, comprising:
a rail track;
a rail-bound vehicle movable along the rail track and including an electric motor, with the aid of which the rail-bound vehicle is able to be driven in a rail direction along the rail track; and
