Definitions

  • the present invention relates to multifunctional fixing profile-members for assembling a subassembly in the underfloor region of a rail vehicle.
  • an object of the present invention is to provide means for the simplified and logistically optimized assembly of subassemblies in the underfloor region of rail vehicles.
  • a multifunctional fixing profile-member for assembling a subassembly in the underfloor region of a rail vehicle, having at least one standardized fixing solution by means of which the subassembly can be releasably connected to the fixing profile-member, and having a first connection region, by means of which the fixing profile-member can be connected in a materially engaging manner to a longitudinal carrier in the underfloor region of the rail vehicle, and having a connection region by means of which the fixing profile-member can be connected in a materially engaging manner to the floor of the rail vehicle.
  • the fixing profile-member according to the invention may advantageously be fixed in a materially engaging manner at any location of the bogie to a longitudinal carrier and the floor of the rail vehicle, wherein the subassemblies to be assembled can be releasably fitted to the rail vehicle by means of the standardized fixing means of the fixing profile-member. It is thereby no longer necessary to store a large number of fixing profile-members which are individualized with respect to the subassembly and the rail vehicle type, but instead it is sufficient to store only one universally usable fixing profile-member.
  • Examples of the standardized fixing solutions which can be provided in the fixing profile-member according to the invention are threaded holes, through-holes for receiving fixing bolts, such as, for example, studs, cable eye reinforcement members, lugs, threaded rods, or the like.
  • Such fixing solutions are preferably suitable for releasably fixing a subassembly to the fixing profile-member by means of a non-positive-locking connection.
  • the fixing profile-member according to the invention preferably has a relatively great thickness in order, on the one hand, to provide sufficient mechanical stability for fixing heavier subassemblies and, on the other hand, to be able to provide the greatest possible compensation for tolerances during the assembly of the subassemblies.
  • a relatively large thickness is intended to be understood to be a thickness in a range between 10 and 30 mm in this instance.
  • the subassemblies may be fitted in the underfloor region of the rail vehicle by means of one or more of the fixing profile-members according to the invention which at any location of a longitudinal carrier in a materially engaging manner, preferably by means of welding techniques. It is thereby possible to be able to freely position the subassemblies in the underfloor region even afterwards, that is to say that it is not necessary already to provide receiving locations for subassemblies during the assembly of the undercarriage on the longitudinal carriers. The assembly flexibility is thereby increased and standardized structural elements can also be used for the longitudinal carriers.
  • connection regions are constructed at the ends of the members of the fixing profile-member in such a manner that a connection region has an abutment face which is formed parallel with the longitudinal extent of the longitudinal carrier and a seam face which forms an angle between 50° and 70° relative to the abutment face, and another connection region has an abutment face which is formed parallel with the plane of the floor and a seam face which forms an angle between 50° and 70° relative to the abutment face.
  • the fixing profile-member it is advantageously possible to connect the fixing profile-member in the region of the seam faces to the longitudinal carrier and the floor in a materially engaging manner, for example, by means of welding, while the abutment faces ensure a reliable orientation of the fixing profile-member relative to the longitudinal carrier and the floor.
  • the abutment faces are arranged so as to be offset relative to the longitudinal axis of the members.
  • the arrangement of the abutment faces so as to be offset relative to the longitudinal axis of the members allows improved accessibility to the seam face and further optimizes the force transmission from the fixing profile-member into the longitudinal carrier, in particular in a vertical direction.
  • the at least one standardized fixing solution comprises a hole, a thread or a possible screwing connection.
  • the provision of such standardized fixing solutions allows the universal applicability of the profile-member for a large number of different subassemblies.
  • the fixing solutions provided in the fixing profile-member are preferably selected in such a manner that all the subassemblies which are intended to be provided in the underfloor region of a rail vehicle can be assembled or fixed with a universally usable profile-member.
  • the fixing profile-member it can be fixed to the longitudinal carrier by means of a weld seam and to the floor by means of a weld seam or at least one welding spot.
  • the fixing profile-member is in the form of an extruded profile-member.
  • an extruded profile which corresponds to the cross section of the fixing profile-member and which is then divided into suitable part-pieces, for example, by means of a saw, water-jet cutting, plasma cutting or the like.
  • the production of the fixing profile-member as an extruded profile-member also results in an optimized grain structure of the material, from which the fixing profile-member is produced, whereby in particular the occurrence of stress cracks as a result of the welding of the profile-member to the longitudinal carrier and/or the floor can be prevented.
  • the fixing profile-member prefferably comprises an aluminum material such as, for example, an aluminum alloy.
  • suitable aluminum alloys are the alloys in accordance with EN 13981-1.
  • FIG. 1 shows the assembly position of an embodiment of a fixing profile-member according to the invention in the underfloor region of a rail vehicle;
