Definitions

  • the invention relates to a two-axle, in particular long, freight wagon with a torsion-resistant base frame which has at least two head girders, this subordinate cross girder and two outer long girders.
  • long two-axle rail vehicles must have sufficient torsional strength with regard to their safety against derailment, the wheel contact points of the wheel sets forming the measurement basis.
  • a torsion ability can be achieved with the appropriate design of the wheel set suspension.
  • a torsional stiffness is required for the vehicle body that is claimed, which is dependent on the vehicle's own mass and the length of the vehicle overhangs. With a lower dead weight and longer overhangs (e.g.
  • the invention is accordingly based on the object of designing a rail vehicle of the generic type on its undercarriage in the sense of a required torsional rigidity, this design being intended to be carried out in the simplest possible manner and in terms of weight.
  • outer long beams are connected to one another by at least four tension members, of which two tension members each lie diagonally to one another and in a common plane, one of these levels above the longitudinal center of gravity of the base frame and the other level below this longitudinal center of gravity is arranged and that both planes each have the greatest possible distance from said longitudinal center of gravity.
  • the object according to the invention is characterized by its particularly simple, inexpensive to produce design and the torsional rigidity achieved in accordance with the regulations, the tension members arranged for this purpose advantageously practically not increasing the vehicle's own mass, which enables an optimally high load mass.
  • Duch DE-C 218 050 a diagonal stiffening for a four- or six-axle bogie freight wagon is known, in which a completely rigid base frame is created with the help of two tie rods which lie in intersecting vertical planes and a vertical support. Because of the different tasks in relation to the subject matter of the invention and in view of the fact that the teaching of DE-C 218050 is directed to a single pair of tie rods which are not in a common plane, this publication is unable to provide any information or suggestions for finding the solution according to claim 1 to convey.
  • the basic structure of the vehicle undercarriage has two head supports 1 (see FIG. 1) with side buffers (not shown) attached to it, cross members 2 arranged downstream of the head supports 1, two outer long supports 3 and middle long supports omitted here.
  • the outer long beams 3 provided with axle holders 7 for wheel sets 8 are designed in the exemplary embodiment in the manner of a fish belly beam (see FIG. 1).
  • the outer long beams 3 are connected to each other to achieve a higher torsional rigidity by upper and lower tension members 4a and 4b, which are arranged diagonally above and below with the greatest possible distance to the longitudinal center of gravity of the base frame.
  • the upper and lower tension members 4a and 4b extend over a longitudinal section delimited by a pair of cross beams 2 ', these cross beams 2' being connected to the long beams 3 in the region of their transition from constant beam height to increasing beam height.
  • the upper tension members 4a which are made of flat profiles with regard to the greatest possible distance from the longitudinal center of gravity, are arranged horizontally above the crossbeams 2 and connected to the outer crossbeams 3 in their node area with the two crossbeams 2 'by welding.
  • the lower tension members 4b consist of three diagonally crossing pairs, of which the middle pair is arranged within the longitudinal section of the constantly increased height of the long beams 3.
  • the two outer pairs of the lower tension members 4b lie within those long beam transition sections which are delimited by the ends of the aforementioned longitudinal section and the areas of the transition from constant to increasing beam height (cross beam 2 ').
  • transversely arranged tubes 5 which are provided as spacers between the points of engagement of the middle pair and the two outer pairs of the lower tension members 4b on the long beams 3, prevent deformations of the long girders 3, these tubes 5 also serving the torsional rigidity.
  • the long girders 3 have web plates 6 arranged in the area of the abovementioned points of attack as stiffeners.
  • the lower tension members 4b consisting of a round profile are tensioned. Locks 4c adjustable in length. A corresponding adjustability could also be present for the upper tension members 4a. Due to the length adjustment, a tight fit and even a favorable pretensioning of the tension members 4b can easily be achieved.
  • the lower tension members 4b are detachably connected to the outer long beams 3 via bolts 4d.
  • the lower tension members 4b are held in their respective crossing point by a base plate 9, to which conventional clamps, which surround the tension members 4b, are fastened.
