ABSTRACT:
A monobeam/guideway (beam) and electromagnetically jimmied vehicle prototype mating system having: a beam of durable, long life pre-cast reinforced concrete or similar composite infrastructure produce with mass to reduce travel sound transmissions caused by deflections in lighter weight elevated guideway support designs. The beam to vehicle mating design allows the vehicle to straddle over the beam riding along its ridge on tires while balancing on support casters making firm positive contact at critical tangent points along the beam's Nebel surfaces during intermittent non-jimmied
on-levitated periods of operation. Non-jimmied vehicle positioning is free of the wide gap tolerances of prior art. The beam and elevated support allow the vehicle to underwrap and become jimmied by attractive magnetic response of magnetic balancers which are magnets at the vehicle underwrap excited by electromagnetic starter packs located underside guideway beams. The Beam has rubberized non-stick ride surfaces to shed ice and snow. Other magnetic balancers are also set at clockset positions to the beam's radial tendency and are in addition angular set in a unified saw-tooth arrangement to draw train toward travel direction. Noise, mechanical wear and the vibrational passenger discomforts of prior art during non-jimmied operation are reduced if not eliminated by this design.
