    • B61F1/00—Underframes

Definitions

  • the invention relates to a base frame for rail freight wagons without torsionally rigid car bodies, at least consisting of outer side members and cross members fixedly arranged between them, and at least one additional hollow member arranged between the outer side members in the transverse direction of the wagon and torsionally connected to the outer side members.
  • the torsional stiffness of the wagon In order to ensure derailment security for long two-axle freight wagons, the torsional stiffness of the wagon must therefore be precisely defined, the torsional stiffness depending on the length over buffers and the weight of the wagon. The lighter the car, the higher the torsional stiffness.
  • a base frame for rail freight wagons is known, in which the cross members arranged between the outer side members in the wagon transverse direction are articulated to the side members.
  • These known underframes are intended to carry both the car body and the drives, as well as head carriers on the front sides for receiving central buffer couplings.
  • Such an articulated connection between cross members and side members is intended to achieve a high torsional strength of the underframe.
  • This is intended to solve the problem of making central buffer couplings usable for biaxial rail vehicles without bogies, without endangering the safety against derailment.
  • an extreme torsional strength of the underframe is therefore sought to increase the safety against derailment, specifically for those underframes in which both a stiffening frame for the car body and head supports for receiving middle buffer couplings are integrated.
  • this known hollow beam is provided with solar break points.
  • the hollow cross member is rotatably mounted in the area of additionally provided central struts. These center struts are necessary due to the eccentric mounting, in order to be able to better transfer the moments emanating from the coupling into the base frame.
  • the object of the invention is to precisely define the torsional value of the undercarriage and thus the railway freight wagon within the permissible values for undercarriages of railway freight wagons of the type mentioned at the outset with little economic outlay.
  • the system not yet containing the hollow beams from the outer longitudinal beams and the cross beams fixed between them has such a low torsional stiffness that this torsional rigidity alone is still too low for the base frame that the Desired and required torsional rigidity of the base frame is achieved in that each of the hollow beams with a specifically defined torsional rigidity ver it can be seen that this torsional rigidity determines the torsional rigidity of the entire underframe and thus of the rail freight wagon, and that openings on the underside of the hollow girders determine the size of the torsional rigidity of the hollow girders by shape and size or the cross sections of the hollow girders or the wall thickness of the hollow girders or several of these parameters .
  • the hollow beams which are designed to be torsionally rigid, the undercarriage of the rail freight wagon and thus the entire rail freight wagon can be designed to be torsionally rigid within the framework of the specified target values.
  • the hollow beams can be box-shaped with a rectangular cross-section and as a component integrated in the crossbeams of the base frame for additional transfer of vertical forces.
  • the hollow support can be tubular with a round cross section.
  • the hollow girders are arranged either in the center of the wagon or, if several hollow girders are required, symmetrically on both sides to the center of the wagon or in the center of the wagon and symmetrically on both sides of the center of the wagon. Due to the possible arrangement of one or more hollow girders, extremely torsion-resistant bases can be equipped with the required torsional rigidity. When the hollow girders are designed as a box-shaped component, they can replace one or more cross girders and can also be used to transfer the vertical forces arising from the payload.
  • the underframes for pulling the rail freight wagons are sufficiently torsionally soft to keep wheel relief in the area of canting ramps, in particular S-curves, and in the event of track errors within the permissible limits, and on the other hand sufficiently rigid for pushing the rail freight wagons are in order to keep the wheel relief of the wheels inside the curve within the permissible limits.
  • These advantages are particularly noticeable at extreme, e.g. more than 13m long and / or only two axes underframes are particularly noticeable.
  • the torsional stiffness is higher the lighter and / or longer the rail freight wagons are.
  • the number of crossbeams which are always required apart from the hollow beams and are fixedly arranged between the longitudinal beams is not important for the application of the invention.
  • hollow beams 2 are arranged between the outer side members 1 and connected to the outer side members 1 in a torsion-resistant manner.
  • the hollow beams 2 are box-shaped with a rectangular cross section, the wall thickness of each hollow beam and its cross section being dimensioned in accordance with the torsional forces to be absorbed.
  • Openings 3 are arranged in the underside 2a of the hollow beam, by means of which the dimensions can be used to subsequently fine-tune the torsional rigidity.
  • Each hollow beam 2 is integrated in the system of the cross member 4 of the base frame that it is used either directly as a support for the floor 5 or indirectly via the floor support 6 to support the floor 5.
  • the hollow beams 2 can be arranged in the longitudinal center of the carriage, symmetrically on both sides of the longitudinal center of the carriage or in the center of the longitudinal carriage and symmetrically on both sides of the longitudinal center of the carriage.
  • tubular hollow girders 9 with a round cross section are arranged in the underframe of the railway freight wagon between outer longitudinal beams 8.
  • the dimensioning of these hollow girders9 in cross-section and in their wall thickness is again carried out in accordance with the required torsional rigidity.
  • these tubular hollow beams 9 can be arranged again in the longitudinal center of the wagon, symmetrically on both sides of the wagon longitudinal center or in the wagon longitudinal center and symmetrically on both sides of the wagon longitudinal center.
