Definitions

  • the invention relates to a magnetic rail brake arrangement for two-axle rail vehicles with bogies that can be pivoted about a pivot box-fixed pivot bearing.
  • Magnetic rail brakes are known, they are arranged in particular in rail vehicles with multi-axle chassis between the axles of the chassis.
  • the overlap between the brake magnet and the rail is essentially retained even when cornering.
  • the situation is different for biaxial rail vehicles, e.g. Rail buses, in which the magnetic rail brake is arranged on the car body between the axles, because then when braking, the brake magnets are displaced relative to the rail transversely to the direction of travel, whereby the degree of overlap between the brake magnet and rail is reduced or disappears completely.
  • this also applies to two-axle rail vehicles with bogies that can be swiveled around a carriage-mounted pivot bearing.
  • the object of the invention is to equip two-axle rail vehicles of the type described at the outset with magnetic rail brakes which are always guided over their associated rail even when cornering.
  • the object is achieved in that a carriage supported on the car body and displaceable transversely to the direction of travel is arranged in the direction of travel, which carries brake magnets arranged at the rail spacing, and that a lever mechanism is arranged between the chassis and the carriage, which when pivoting of the chassis directs the brake magnets held on the sled over their assigned rails.
  • the lever gear can easily be designed so that it depends on the distance of the brake magnets from the axis of the assigned chassis the brake magnets so that there is always an optimal degree of coverage between the brake magnet and the associated rail even when driving through curves with any curve radii.
  • the lever mechanism can have a translation lever pivotally mounted on the car body, to which the slide and a control rod connected to the chassis are articulated.
  • the length of the control lever but in particular the distances between the articulation points of the slide and control rod to the carriage-side bearing of the transmission lever, the deflection of the slide or the brake magnet can be adapted to the respective design circumstances.
  • An embodiment has proven itself in practice in which the control rod is arranged on the transmission lever between the articulation point for the car body and the articulation point for the carriage.
  • control rod has a forked end which is connected to the drive on both sides of the pivot bearing.
  • the carriage expediently has vertical guides for the brake magnets.
  • Actuating cylinders for the brake magnets should be provided so that the brake magnets can be arranged in the rest position at a greater distance above the associated rail, as is customary in the case of full railways.
  • the brake magnets are expediently positioned via centering cones in rubber-elastic cone bearings.
  • the Actuating cylinders are mounted directly on the slide. In this case, the actuating cylinders should be gimbaled at least on the slide side.
  • a chassis 1 can be seen with an axle 2 mounted therein and associated wheels 3 of a two-axle rail vehicle.
  • the chassis 1 is mounted on its side facing the center of the car via a pivot bearing 4 pivotable about a vertical axis on the car body, not shown.
  • On both sides of the pivot bearing 4, fork-shaped ends of a control rod 5, 6 are connected to the chassis 1.
  • the other end of the control rod 5, 6 is articulated at 7 to a transmission lever 8, specifically with a link guide which is effective in the direction of travel and which is designed as an elongated hole in the embodiment shown in FIG. 1.
  • the transmission lever 8 is mounted on the car body in a pivot bearing 9 which is fixed to the car body and can be pivoted about a vertical axis.
  • the translation lever 8 has at its free end a further articulation point 10 for a carriage 11, which is held under the car body and is displaceable in the guides 12 transversely to the direction of travel relative to the car body.
  • the carriage 11 carries brake magnets 13 which are arranged at the rail spacing and are located above the associated rails when driving straight ahead.
  • the brake magnets 13 can be moved up and down in vertical guides 14 of the slide 11, with the aid of actuating cylinders 15 which are arranged on the car body in the embodiment according to FIG. 1 and are connected to the brake magnets via flexball cables 16.
  • the magnetic rail brake arrangement shown functions as follows: As long as the rail vehicle is moving in a straight line, the brake magnets 13 are located above their assigned rails. For braking, they are lowered onto their associated rails with the aid of the actuating cylinders 15, an optimal degree of coverage being established between the brake magnet 13 and the associated rails. When cornering, the chassis 1 pivots about its pivot bearing 4. The control rod 5, 6 is also deflected, which pivots the transmission lever 8 about its pivot bearing 9. As a result, the carriage 11 is moved transversely to the direction of travel so that the brake magnets 13 are always with an optimal degree of coverage over their associated rail.
  • the articulation point 7 between control rod 5, 6 and transmission lever 8 is a simple pivot bearing.
  • the transmission lever 8 is articulated via a compensating lever 17 with its pivot bearing 9 and the slide 11 via a compensating lever 18 with its articulation point 10.
  • the compensating levers 17, 18 take out the longitudinal displacements of the components that occur when the chassis 1 is pivoted.
  • actuating cylinder 15 can also be arranged directly on the carriage 11, wherein they should be gimbaled at least on the slide side.
  • the brake magnets 13 are positioned in the rest position, that is to say centered in the upper position in rubber-elastic conical bearings 19.
