Definitions

  • the invention relates to a frame of a rail vehicle, in particular a freight car with profiled side members, which extend at least in the lateral edge regions of the rail vehicle substantially over the entire length of the frame and with at least one lower flange which runs in the longitudinal direction of the rail vehicle in terms of height below the side members and connected to the side members, preferably welded.
  • the object of the invention is to provide a frame for rail vehicles which has a low overall height above the wheels with the largest possible diameter and is nevertheless torsionally and flexurally rigid.
  • the lower flange (s) is (are) arranged in the bottom region of a hollow beam, which is connected to the longitudinal beams, the hollow beam extending essentially over the entire length of the frame and the hollow beam - in the longitudinal direction seen in the rail vehicle - is lowered lower in the area between the wheels and runs above the wheel axles in the area of the wheels.
  • the continuous profiled side members allow high torsional rigidity.
  • the use of cold-formed steel profiles which are profiled in a wave or meandering shape is particularly advantageous.
  • at least one lower flange is connected to these torsionally rigid longitudinal beams, which runs below the longitudinal beams in height and is arranged in the bottom region of a hollow beam which is connected to the longitudinal beams.
  • the hollow beam allows a particularly favorable connection of the lower chords with the longitudinal beams and is itself a torsionally rigid construction element.
  • FIG. 1 shows a cross section through a first exemplary embodiment in the region of the wheel axle.
  • Fig. 2 shows a cross section through the frame of this embodiment between the wheel axles or bogies.
  • 3 and FIG. 4 each show a section through further exemplary embodiments in the area of the wheel axle.
  • 5, 6 and 7 show partially schematic longitudinal sections according to the section lines A-A, B-B, C-C of FIGS. 1 and 2 or 3 and 4 respectively.
  • FIGS. 1, 2 and 5 of a frame of a freight car has meandering profiled side members 1 made of cold-formed in the lateral edge region of the rail vehicle Steel profiles.
  • this has lower chords 4 and 12, which run below the longitudinal beams 1 in height and, if appropriate, are connected, preferably welded, with the interposition of further elements.
  • the lower chords 4 and 12 are at different heights, as seen in the longitudinal direction of the rail vehicle. Between the front and rear bogies, the lower chords 12 are lower and thus increase the load capacity there.
  • the lower flange 4 is higher, namely above the wheel axle 15.
  • the lower chords 4 and 12 are arranged in the bottom region of a hollow beam 17 which is connected to the longitudinal beams 1.
  • the remaining walls of the hollow beam 17 can in turn be formed by profiled longitudinal beams 3 or 11 or simple flat plates 5.
  • the hollow beam 17 - seen in the cross section of the rail vehicle - is only arranged in the central region lying between the wheel disks 16. This is sufficient to ensure the bending rigidity of the frame sufficiently.
  • the profiled longitudinal beams 1 are provided anyway for the necessary torsional rigidity.
  • the longitudinal members 1 are connected in the area above the wheels 16 (FIG. 1) to the upper belts 2 which run in the longitudinal direction of the rail vehicle and are arranged exactly above the wheel disks. About these top chords 2, the side members 1 with the middle Hollow carrier 17 connected in the region of the wheels 16.
  • the upper straps 2 and the lower straps 4 and 12 are made of flat metal plates, the thickness of which is greater than the wall thickness of the side members 1.
  • the side members 1 have an angled end 1 a, which runs essentially in the plane of the top chord 2.
  • a plurality of cross members 14 running transversely to the longitudinal direction of the rail vehicle are provided, which are connected to the continuous longitudinal members 1.
  • the cross members 14 are advantageously cut out according to the cross-sectional shape of the side members 1 and thus follow the course of the underside of these side members 1.
  • the cross members 14 can be welded to the side members 1 and the central hollow member 17, from which they extend laterally outwards.
  • the frame at the top has a flat surface on which a loading floor 13 can be attached.
  • the frame according to the invention is suitable not only for wheel sets with a continuous wheel set shaft 15 and shoe brakes, but also for wheel axles with one or two shaft brake discs 18, as shown in FIGS. 3 and 4.
  • a profiled longitudinal member 6 is provided in order to connect the upper flange 2 to the lower flange 4. Due to the special profiling of the longitudinal beam 6, the area required for the shaft brake disks 18 can be left out without significantly impairing the strength.
  • the lower flange 4 is divided, i.e. there are two parallel lower chords which are connected to one another in the region of the bogie by a profiled longitudinal member 9.
