SCHAKELING VOOR HET BEKRACHTIGEN VAN DE HOOFD- EN HULPELEKTROMAGNETEN VAN EEN ZWEEF- SPOORVOERTUIG.

摘要

An electromagnetic suspension vehicle system comprising a track having a pair of main armature rails on opposite sides thereof, a switch portion in which at least one of said main armature rails is interrupted, and a pair of auxiliary armature rails at least at selected locations of the switch portion. A vehicle is displaceable along the track and has at opposite sides thereof respective main electromagnets respectively cooperating with the main armature rail, and auxiliary electromagnets cooperating with the auxiliary armature rails at least at selected regions of the switch portion for suspending the vehicle on the track in the absence of suspension force from an associated main electromagnet. Separate exciting current sources are provided for each of said main electromagnets. A common exciting current source for both said auxiliary electromagnets on opposite sides of the vehicle cooperates with switching means for selectively connecting the common exciting current source with a selected auxiliary electromagnet on only one side of the vehicle.
