  • Publication number: 20070289477
    Abstract: The invention relates to a railway track for vehicles with various means of locomotion and drive systems, enabling transitions from one type of roadway to another type of roadway to be carried out smoothly. The invention also relates to vehicle that is adapted to said railway track in an optimum manner and, if necessary, can travel without the railway track. The inventive railway track (2) consists of two parallel rails (7) provided with one or two wing-type extension arms (9), enabling vehicles to travel on the track with a flange wheel (5) as well as a road wheel (4), and with magnetic levitation (6).

  • Publication number: 20040250724
    Abstract: A combination vehicle for the use of various roadways. The combination vehicle (1) consists of a traction. head (14) and a trailer element (15) for requirements of various types of use and in this combination, is determined for three alternative types of locomotion including wheel/road (6), whecl/rails (7) and magnetic levitation (8). For the whecl/rails (7) and wheel/road (6) types of locomotion, the vehicle is provided with a combined flange wheel (5) and street wheel (4). For its use as a maglev vehicle, at least four supports (11) with extendable or swing-out current-carrying magnetic coils (12) and asynchronous short-stator motors (13) arc arranged on both sides of the chassis.%! For the transition from one type of locomotion to another, the roadways (6, 7) are lowered relatively to each other using ramps. To overcome points of discontinuity such as intersections (38), switches (39) and level crossings, roadway sections (40, 41, 42, 43, 45) are lowered or swung out in relation to each other.
