Abstract

A track-guided transport vehicle system for transporting high loads along a travel path contains for the drive a synchronous linear drive with a long stator along the travel path and an exciter winding on the vehicle. The long stator generates a travelling field that cooperates with a static magnetic field generated by an exciter winding on the vehicle so as to propel the vehicle. In order to supply electric drive energy to the compressor unit serving to generate compressed air for the air cushions, a higher frequency alternating current is superimposed on the current supplied to the windings along the track, with the higher frequency alternating current being coupled by a transformer effect into the winding on the vehicle. The energy can be coupled out there by means of a rectifier and be made available for feeding the electric motor of the compressor unit.
