Abstract

The invention relates to a magnetic levitation railway provided with an eddy-current brake (20) interacting with a reaction rail (8) of a travel way (2). Said invention is characterised in that said eddy-current brake (20) comprises at least one brake magnet which is movably mounted on a vehicle (16) in a perpendicular direction with respect to the reaction rail (8) and is applied thereto when a normal force exceeds a value determined, for example by a springs (27).

Description

technical field

[0001] The invention relates to a magnetically levitated railway of the kind stated in the preamble of claim 1 and to a magnetically levitated vehicle for such a railway. Background technique

[0002] Known maglev railways of this type are driven, for example, by long-stator linear motors provided with three-phase AC windings located in long stators alongside the guide rails. The excitation field of the linear motor is supplied by a support magnet which simultaneously acts as an excitation magnet and is arranged in the vehicle (DE 3919058 C2). In addition to driving, linear motors can also be used to brake the vehicle. For this purpose, it is only necessary to supply the three-phase AC windings of the associated long stator with a current having a sign opposite to that of normal operation during driving.

[0003] Since there is no possibility of braking when e.g. individual magnets or all supporting and exciting magnets fail to work, magnetically levitated ...
