Abstract
A magnetic levitation railway having an eddy-current brake (20) cooperates with a reaction rail (8) of the driveway (2). The eddy-current brake (20) has at least one brake magnet (21) which is movably mounted to the vehicle (1) and transversely to the reaction rail (8) and which is made to abut the reaction rail (8) if a normal force, for example, fixed by means of springs (27) is exceeded.
Claims6
A magnetic levitation railway, comprising:
- a driveway (2, 3) having a reaction rail (8);
- and
- a vehicle (1) being movably arranged on the driveway in parallel to said reaction rail (8) and being provided with an eddy-current brake (20), said eddy-current brake (20) having at least one brake magnet (21) destined to cooperate with the reaction rail (8) and to keep a certain distance to said reaction rail, said at least one brake magnet (21) having at least one magnet pole provided with a winding (25), said magnet pole developing apart from a braking force acting in the direction of travel also a normal force acting vertically to the reaction rail (8) and depending on the travel speed when said winding (25) is excited,
- wherein said brake magnet (21) includes a gliding plate (34) and movably mounted to the vehicle (1) and transversely to the reaction rail (8) in such a manner that said at least one brake magnet (21) abuts said reaction rail (8) with said gliding plate (34) when a normal force exceeds a pre-determined value, wherein a frictional force occurring as soon as the at least one brake magnet (21) rests against the reaction rail (8) renders an additional braking effect, and wherein said gliding plate (34) covers said windings of said brake magnet (21).
A magnetic levitation vehicle for magnetic levitation railways, wherein said vehicle is equipped with an eddy-current brake (20), said eddy-current brake (20) having at least one brake magnet (21) destined to cooperate with the reaction rail (8) and to keep a certain distance to said reaction rail, said brake magnet (21) having at least one magnet pole provided with a winding (25), said magnet pole developing apart from a braking force acting in the direction of travel also a normal force acting vertically to the reaction rail (8) and depending on the travel speed when said winding (25) is excited,
- wherein said brake magnet (21) includes a gliding plate (34) and movably mounted to the vehicle (1) and transversely to the reaction rail (8) in such a manner that said at least one brake magnet (21) abuts said reaction rail (8) with said gliding plate (34) when a normal force exceeds a pre-determined value, wherein a frictional force occurring as soon as the at least one brake magnet (21) rests against the reaction rail (8) renders an additional braking effect, and wherein said gliding plate (34) covers said windings of said brake magnet (21).
