  • the present invention relates to an elcctromagnet ically driven high-speed elevated railway car system having a linear induction motor and associated with a guide beam for movement there-along.
  • the prior-art systems have a number of disadvantages, which result in particular from maintaining the respective clearance between components gliding past one another, thereby forming a narrow gap, while cruising, starting up and switching off, with support of the vehicle being provided by means of mechanical emergency support elements in the event the lifting magnets fail, are not yet functioning or are no longer functioning.
  • the narrow gap, on the one hand, and the necessity of keeping the linear motor free between the vehicle and the guide beam so as not to damage the motor on the other hand, necessitate extremely rapid response ofthe mechanical emergency elements, which either cannot be achieved or can only be achieved a complex structure.
  • a railway car system arrangement wherein the lifting magnets, linear motors and corresponding aluminum and steel reaction rails be arranged beneath a portion of the guide beam.
  • the present invention permits a certain shifting movement of the vehicle between non-acting ofthe lifting magnets and response of the mechanical emergency support element. without the linear motors being damaged by such shifting.
  • FIGS. Ia and 1b are partial schematic cross sectional illustrations of electromagnetic railway car and guide beam arrangements in accordance with the prior art
  • FIGS. 2a and 2b are partial schematic cross sectional illustrations of electromagnetic railway car and guide beam arrangements in accordance with the present invention wherein the railway car is mounted for movement above the guide beam;
  • FIG. 3 is a side view partially in cross section of a railway car and guide beam arrangement in accordance with the present invention wherein the car is mounted for movement below the guide beam.
  • FIGS. la and 1b show two examples of prior art vehicle and track sys tents of the type which can be provided with separate optimization of the main electromagnetic components, i.e., the driving and supporting systems.

  • lateral driving magnets 7 are arranged vertically adjacent the faces of the inwardly directed portion of the support rail 6 or a corresponding steel reaction rail located thereat.
  • the bottom ends of the sides of the vehicle are curved in ward to create space for the linear motors on both sides of the vehicle, which also results in unfavorable condi tions with respect to the emergency support system.
  • FIGS. 2 and 3 of the drawing the disadvantages of the prior art system arrangements are overcome by the arrangements illustrated in FIGS. 2 and 3 of the drawing.
  • the vehicle 3 is arranged for movement above the guide beam 5 and the lateral guiding magnets 7 are arranged on the vehicle opposite a canted bottom portion of the support rail 6 while the lifting magnets 4 and the driving magnets 2 of the linear motor are arranged in line one behind the other opposite the bottom of the inwardly directed portion of the support rail 6.
  • the steel reaction rail 60 for the lifting magnets 4 and the aluminum reaction rail 1 for the linear motors are located one above the other on the support rail of the guide beam.
  • FIG. 3 illustrates an arrangement wherein the vehicle is positioned for movement below the guide beam rather than moving the guide beam as illustrated in FIG. 2.
