Abstract
An improved electrodynamic suspension guidance system for a moving vehicle in which primary conductor loops or magnet coils are mounted to a vehicle in rows parallel to the travel direction, with pairs of magnet coils disposed horizontally one above the other to form a zero flux system with a secondary conductor loop or conductor plate or rail disposed along the road bed, in which the magnet field generated by the upper magnet coil in at least some of the pairs is stronger than the magnetic field generated by the corresponding lower magnet coil of the pair in order to obtain a symmetrical position of the magnet coils with respect to the conductor plate thereby compensating for vehicle weight such that the suspension height tolerances are not decreased.
Claims5
In an electrodynamic suspension guidance system for a track-bound moving vehicle which includes rows of vehicle mounted pairs of magnet coils the coils in each pair disposed horizontally one over the other with a gap between, the pairs disposed one behind the other in the travel direction and which magnet pairs cooperate with secondary conductor means, of a nonmagnetic electrically conductive material mounted to the roadbed and disposed in said gap, to form a zero flux system, which is self-controlling wherein the improvement comprises at least some of the magnet coil pairs arranged so that the upper magnet coil generates a magnetic field which is stronger than the magnetic field generated by the lower magnet coil the difference being such as to cause the distances between the reaction rail and the respective magnet coils to be approximately equal.
