Definitions

  • the invention relates to a rail vehicle with an underframe, which has at least two long beams, each with a lower chord and an upper chord and at least one web connecting the lower chord and the upper chord, which extends essentially over the entire length of the long beams, the long beams via at least one cross element are connected to one another to form a supporting structure, the web being corrugated at least in sections, and the generatrix of the corrugations of the web running essentially parallel to the height of the web.
  • the length of the gusset plate is independent of the phase position of the waves of the web.
  • a universal gusset plate can thus be produced thanks to the invention.
  • the expensive manufacture of gusset plates specially adapted to the phase position of the web can thus be dispensed with.
  • the at least one slot runs essentially parallel to the height of the web, a lower edge of the slot being spaced apart from the lower flange or an upper edge of the slot being spaced apart from the upper flange.
  • the slot extends up to either the upper chord or the lower chord, the gusset plate running essentially normal to the web and parallel to its wavefront.
  • This embodiment makes it easy to assemble the gusset plates, since the gusset plates can be inserted into the slot from above or below.
  • the gusset plate is advantageously supported with a lower end region on the lower flange (FIG. 1) and / or with an upper end region on the upper flange, the gusset plate being welded to the respective belt of the long beam.
  • the gusset plate is supported on an end region closer to the lower flange or the upper flange at a lower or upper edge of the slot (FIG. 2).
  • a tubular support for the gusset plate can be provided on one edge of the slot, the longitudinal central axis of which extends essentially normal to the surface of the web (FIG. 3, FIG. 4).
  • FIG. 1 shows a cross section through a section of an underframe of a rail vehicle according to the invention in accordance with a first variant of the invention
  • FIG. 2 shows a cross section through a section of an underframe of a rail vehicle according to the invention in accordance with a second variant of the invention
  • FIG. 3 shows a cross section through a section of an underframe of a rail vehicle according to the invention in accordance with a third variant of the invention
  • FIG. 4 area IV from FIG. 3 in more detail
  • FIG. 5 shows a long girder of a rail vehicle according to the invention in a first perspective view
  • Fig. 6 shows the long beam from Fig. 5 in a further perspective view
  • the underframe of a rail vehicle has at least two long beams 1, 1 ', each with a lower flange 2a, 2a' and an upper flange 2b, 2b 'and at least one web 3 connecting the lower flange 2a, 2a' and the upper flange 2b, 2b ' , 3 ', the web 3, 3' running essentially over the entire length of the long beams 1, 1 '.
  • the long beams 1, 1 ' are connected to a supporting structure via at least one cross element 4, floor supports 5 extending in the longitudinal direction being located on the cross elements 4.
  • the long beams 1, 1 ' have an I-shaped cross section, the web 3, 3' being corrugated at least in a central section of the long beams 1, 1 '(FIGS. 5, 6, 7).
  • the web 3, 3 'can be designed as disclosed in AT 408 334 B.
  • the web 3, 3 'can be produced from a corrugated sheet, the corrugated front of the corrugated sheet extending essentially normal to the longitudinal direction of the long beam 1, 1'.
  • the generatrices of the waves of the web 3, 3 ' thus run essentially parallel to the height of the web 3, 3' or in other words, the radii of curvature of the waves lie in planes which are substantially normal to the height of the web 3, 3 'run (Fig. 5, 6, 7).
  • the stiffness of an I-beam with a corrugated web 3, 3 'compared to that of a carrier with a smooth web is higher for the same dimensions in terms of weight, since the weight of the corrugated web 3, 3' can be made significantly less by reducing its thickness can.
  • the buckling stiffness under bending stress is also significantly greater in the case of a corrugated web 3, 3 'than in the case of a flat web if a corrugated sheet is used which has a considerably greater profile height than the flat, thicker sheet, which is also due to this, that it has almost no free buckling fields due to its corrugated shape.
  • the weight of a corrugated web 3, 3' can be reduced to at least 50% of the weight of a flat web.
  • the web 3, 3 'of the long beam 1, 1' can be used both with the lower flange 2a, 2a 'and with the upper flange 2b, 2b' of the long beam 1, 1 'on both sides d. H. be welded with a double fillet weld, not shown here.
  • the long girder 1, 1 ' is equipped with one or more gusset plates 6, 6' for the connection of cross girders 4 or other assembly parts.
  • the web 3, 3 ' has a slot running parallel to the height of the corrugated sheet, through which the gusset plate 6, 6' or the gusset plates are inserted and welded to the web 3, 3 'in such a way that the gusset plates 6 are essentially normal to the corrugated metal web 3, 3 'and parallel to the wavefront.
  • the gusset plate 6, 6 ' is used to attach the cross member 4 on one side of the long member 1, 1' and the attachment of other mounting parts such.
  • the length of the gusset plate 6, 6' in an assembled state is independent of the phase position of the shafts of the web 3, 3 '.
  • a gusset plate 6, 6 ' which can be used universally can thus be produced, the shape of which is independent of the corrugated plate of the web 3, 3'. If a gusset plate 6, 6 'is only required on one side of the long beam 1, 1' due to its function, the same connection can be used by slitting the web 3, 3 'and pushing through and welding the gusset plate 6, 6'. The same shape can also be maintained if the protrusion on the other side of the web 3, 3 'remains unused.
  • the web is slotted to about 3 ⁇ of its height and the gusset plate inserted through the web 3, 3 'extends on the inside to the lower flange of the long beam 1, 1' and is welded to it ,
  • the lower edge of the slot is thus spaced from the lower flange 2a, 2a ', the upper end of the slot being able to extend to the upper flange 2b, 2b'.
  • the slot in the web 3, 3 ' can be opened and can only be closed by mounting the upper chord 2b, 2b'. In this way, simple positioning of the gusset plate 6, 6 'in the slot can be ensured because it can be inserted into the contactor from above.
  • the upper edge of the slot can also be spaced from the upper flange 2b, 2b ', the slot being able to extend to the lower flange 2a, 2a'.
  • the web 3, 3 ' is also slotted up to approximately 3 A in height, the gusset plate 6, 6' being welded to the contactor.
  • the gusset plate 6, 6 ' is supported on an end region closer to the lower flange 2a, 2a' on a lower edge of the slot.
  • the connection of the gusset plate 6, 6 'to the web 3, 3' is carried out as gently as possible and without a large jump in stiffness.
  • the gusset plate 6, 6 ' can also be supported with an end region closer to the upper flange 2b, 2b' on an upper edge of the slot.
  • a tubular support 7 for the gusset plate 6, 6 ' is provided on the lower edge of the contactor, the longitudinal central axis ⁇ of which extends essentially normal to the surface of the web 3, 3', the Gusset plate 6, 6 'and the support 7 are welded together.
  • the account sheet ends at its lower end on a tube which serves to reduce the stress peaks in the web 3, 3 'at the end of the account sheet.

Abstract

L'invention concerne un véhicule ferroviaire comportant un châssis qui présente au moins deux longerons (1, 1'), pourvu chacun d'une membrure inférieure (2a, 2a') et d'une membrure supérieure (2b, 2b'), ainsi qu'au moins un élément jointif (3, 3') qui raccorde la membrure inférieure (2a, 2a') et la membrure supérieure (2b, 2b') et qui s'étend pratiquement sur toute la longueur des longerons (1, 1'). Ces derniers (1, 1') sont raccordés mutuellement par l'intermédiaire d'au moins un élément transversal (4) de manière à former une structure portante. L'élément jointif (3, 3') est au moins partiellement ondulé et les génératrices des ondulations de l'élément jointif (3, 3') s'étendent de manière sensiblement parallèle à la hauteur de l'élément jointif (3, 3'). Ce dernier (3, 3') comporte, dans une partie ondulée, au moins une fente traversée par un gousset (6, 6').
