Definitions

  • the invention relates to an underframe of a rail vehicle, comprising two head pieces that can be supported on wheels and a central support connecting the two head pieces, each head piece and the central support being detachably connectable to one another via a connecting flange formed from a first flange plate assigned to the central support and a second flange plate assigned to the head piece are, wherein the first and second flange plate form a vertical contact plane in the connected state, as well as a rail vehicle with such an underframe.
  • Rail vehicles with generic underframes are already known from the prior art. As a rule, these are carrier wagons on which containers or other superstructures for transporting payloads that cannot be loaded in containers (e.g. round wood) can be placed.
  • the DE 69 30 111 U and the WO 2018/219955 A1 in each case a subframe composed of three prefabricated assemblies, with two identical head pieces each having a central element of different lengths being connectable.
  • subframes of different lengths should be easy and inexpensive to produce.
  • DE 42 29 481 C1 discloses an underframe for rail freight wagons, the basic concept of which provides for a combination of different modules or subassemblies, including, among other things, the combination of two end pieces with a central element made up of transverse and longitudinal beams. Due to the largely autonomous prefabrication of each individual assembly, in particular the head pieces and the running gear frame, in independent devices, the effort for adjustment and alignment work when assembling the various assemblies should be reduced.
  • the invention is therefore based on the object of providing an underframe for a rail vehicle, comprising two head pieces that can be supported on wheels and a center girder connecting the two head pieces, each head piece and the center girder each having a first flange plate assigned to the center girder and a second flange plate assigned to the head piece formed connection flange are releasably connected to each other, the first and second flange plate form a vertical contact plane in the connected state, to provide, which is easier and cheaper to manufacture and has lower life cycle costs.
  • this object is achieved in connection with the preamble of patent claim 1 in that the first flange plate forms a horizontal contact surface that protrudes beyond the contact plane and the second flange plate forms a horizontal support surface that is set back from the contact plane, the support surface being set up to support the contact surface in the vertical direction is.
  • the first flange plate covers the second flange plate in the vertical direction, ie in the direction of the weight acting on the central support.
  • the flange plate of the central support has, in addition to the conventional, from the prior art, vertically oriented contact surface or contact plane for the transmission of longitudinal forces between the central support and the head piece, a leg which is arranged above this vertically oriented contact surface and protrudes beyond it, on the underside of which a flat and is formed substantially horizontally oriented contact area and with the aforementioned vertically oriented contact surface forms a substantially right angle.
  • the flange plate of the center beam thus forms an approximately L-shaped component.
  • a "horizontal" contact area is to be understood as meaning an area whose spatial orientation is approximately parallel to the horizontal reference plane defined by the contact points of the bogies assigned to the head pieces on the rails.
  • the flange plate of the head piece has - in addition to a vertically oriented contact surface or contact plane for the transmission of longitudinal forces between the head piece and the central beam - also known from the prior art - a support surface arranged at right angles to this on its upper side, the support surface being set back from the contact plane.
  • a connecting flange is thus realized, the first flange plate of which can be supported vertically against the second flange plate by means of a protruding or L-shaped form element.
  • This shaped element is preferably designed as an L-shaped leg which overlaps the upper side of the flange plate of the head piece and is supported by its contact surface in the vertical direction against the horizontal support surface of the flange plate of the head piece.
  • the invention further provides that the first and second flange plates are braced against one another in the horizontal direction by means of locking ring bolts. This enables high forces to be transmitted in the longitudinal direction of the underframe, but at the same time also high stability with respect to bending moments which act on the connecting flange, particularly when the rail vehicle is loaded.
  • the invention also relates to a rail vehicle with an underframe which is designed in accordance with at least one of the aforementioned patent claims.
  • Rail vehicles according to the invention can also be easily adapted to changed transport requirements during their service life with little effort by replacing and/or changing the arrangement of the cross members.
  • FIG 1 is a perspective view of the underframe of a rail freight car according to the invention, formed from a central support (3) and two head pieces (1, 2) at the ends.
  • the couplings and bogies of the rail freight car are arranged in a known manner on the end pieces.
  • the central support (3) forms the central component of the underframe and is designed essentially in one piece; ie a central beam connects both end pieces of the subframe. By varying the length of the central support, base frames of different lengths can be formed.
  • the central support can have a central section and two end sections adjoining the distal ends of the central section, the cross-sectional profile of the central section being larger than the cross-sectional profile of the two end sections.
  • FIG 2 a side view of this base is shown.
  • the connection between one of the two head pieces (2) and the center support (3) is shown separately as detail "A".
  • figure 3 shown.
  • the connection is formed from a first flange plate (4) on a first end face of the central support (3) and a second flange plate (5) on a corresponding second end face of the head piece (2).
  • Both flange plates (4, 5) touch each other with their vertically oriented connection surfaces, so that a common vertical contact plane (E) is formed in the contact area of both flange plates (4, 5).
  • the first flange plate (4) assigned to the central support (3) has in its upper area an L-shaped leg which protrudes in the direction of the longitudinal axis (L) of the central support (3) beyond the vertically oriented connection surface of this first flange plate (4) and on the underside of which a horizontal contact surface (6) is formed.
  • the top of the second flange plate (5) associated with the head piece (2) has a support surface (7) which is also oriented at right angles to its vertical connection surface and is set back in relation to the contact plane (E).
  • the leg of the first flange plate (4) overlaps the second flange plate (5), so that its contact surface (6) vertically against the support surface (7) of the second flange plate (5).
