Abstract

Abstract A ground or top supported tracked vehicle includes a carriage which is suspended above a trackway by air pressure or magnetic force and which is moved along the trackway and braked by a linear electric induction motor. The carriage is supported in spaced relationship to a curved track or rail by the air pressure gap or the magnetic force gap and is maintained during motion without ground or track contact. The carriage is constructed to pivot from a pendular hinge for lateral swinging movement. The pendular axis is located above the center of gravity of the carriage and is advantageously formed at the lower end of an induction motor or as one of the moving parts of the motor. The construction includes sliding pads or rollers which run along a substantially vertically arranged electroconductive reaction rail without being supported vertically on the rail.
