Definitions

  • the invention relates to a rail vehicle with at least two substantially over the Whole width of the rail vehicle extending main cross beams on which floor profiles are fixed, which are substantially parallel to the longitudinal direction of the rail vehicle extend, wherein the main cross member each have a lower flange and at least one upper flange and have intervening webs.
  • a frequently used embodiment of a rail vehicle has two bogies, one in each of the longitudinal end regions of the vehicle, wherein above each bogie a main cross member is provided to the wagon load into the respective bogie. For this reason, it is necessary that the main crossbeam have a correspondingly high bending stiffness. To increase the bending stiffness you can increase the profile height of the main cross member, which essentially the entire Overall height between the upper edges of the bogies and the floor level of the vehicle to reach maximum rigidity. In addition to the main crossbeams are to Support of the floor further cross beams possible.
  • the other embodiment is used when the distance between the Top of the bogies and the floor level of the rail vehicle is too small to Main cross beams with the required profile height to offer space.
  • the upper straps of the main crossbeams replace in the resulting area between the cut floor profiles the tops of the floor profiles that usually make up the floor. This measure serves to ensure that even with a small distance between the upper edges of the bogies and the floor level of the rail vehicle, the main crossmember a sufficiently high Profile.
  • An advantage of continuous floor profiles is that with them the production of the floor can be carried out fully automatically.
  • continuous floor profiles In contrast to non-running, a significant improvement for the welding the floor profiles with the longitudinal beams, and since both the floor profiles as Even the two long beams go through the length of the car, they can be welded by machine become. If, on the other hand, the main crossbeam is inserted into the floor, then it is on the bottom of the floor, the longitudinal weld only partially machined; in the area of the main crossbeams must be welded by hand, whereby the Significantly increase production costs.
  • Another advantage of using continuous Floor profiles is that you through the fully automatic production also a very getting even floor.
  • DE 40 05 287 describes a fischbauchartigen mid-length carrier of a freight car, the has a top flange, which lies in the floor level.
  • US 753 938 A describes a frame for a railroad car, in which each other parallel longitudinal members are provided, two of which as a central longitudinal beams and two are designed as side members, by means of cross members and upholstery elements are connected. Between a side and a middle longitudinal beam associated therewith each arranged a pad element. Another upholstery element is between the two Center longitudinal beams arranged, with the tops of the upholstery elements, the cross member and the side members lie in one plane. Between the side rails and the associated Center longitudinal members and between the center longitudinal members floor plates are provided. In the area above a padded element where these floorboards are contiguous Cover plates arranged.
  • An object of the invention is, even with a very small distance between the top edge the bogie and the floor level of the rail vehicle, the arrangement continuous floor profiles to allow, with the main cross member the required To have bending stiffness.
  • one or more upper straps with the floor profiles To connect is that the at least one upper flange with the top of the floor profiles is welded.
  • a main cross member has two upper straps, which in a predetermined distance from each other with the top of the floor profiles are welded.
  • an air spring whose diameter substantially the width of the main cross member corresponds, provided under the lower flange of the main cross member is, whereby it by the air pressure in the spring to a bending load of the lower flange comes in a favorable embodiment, the plate stiffness of the lower flange To increase locally, a bridge provided under the lying between the upper chords area is.
  • a favorable embodiment of the floor profiles to the flexural rigidity in the area of Main cross member further increase that the floor profiles a triangular Have cross-section.
  • a low weight of the main cross member is achieved by the material of the Main cross member is aluminum.
  • a low weight of the floor can be achieved by the material of the Floor profiles is aluminum.
  • An inexpensive, because easy to manufacture embodiment is that the webs and the lower chord are made in one piece.
  • main cross member which is light in weight has, is that the main cross member is designed as cast aluminum.
  • Another embodiment with low weight is that the main cross member made of large aluminum profiles.
  • floor profiles are provided on a main cross member 2 of a rail vehicle 1 3, the tops 3b can form the floor, attached, as well as from Figs. 2 and 3 becomes apparent.
  • the floor profiles 3 are exactly two upper chords 5a, 5b of the main cross member 2, as shown in FIGS. 2 and 3 can be seen, with the top 3b of Floor profiles 3 are welded.
  • the welding of the upper chords 5a, 5b can be relative be carried out effortlessly, as they are simply placed on the continuous floor profiles 3 and then the side surfaces of the upper belts 5a, 5b are welded to the upper side 3b. Since the welded joints 13 may have a substantially rectilinear course This process can also be performed by machines. This eliminates - in contrast to the usual execution - the time-consuming and costly sections, manual welding the floor profiles 3 with the long beams. 8
  • the floor profiles In order to achieve the necessary flexural rigidity, the floor profiles have 3 diagonal infills 9 on. Below the floor profiles 3 webs 6a, b, c of a lower flange. 4 of the main cross member 2 to the bottom 3a of the floor profiles 3 executed and with the Bottom 3a of the floor profiles 3 welded. The welding of the bottom 3a with the Webs 6 can also be done by machine because of the broadening 7 of the web ends.
  • a bogie not shown here is provided, wherein the Introduction of the car load in the bogie over the main cross member 2 takes place.
  • the main cross member 2 with long beams 8, which is substantially extend over the entire length of the rail vehicle to a load-bearing structure connected, wherein the longitudinal beam 8 connects to the lower ends of side walls 10 of the rail vehicle, which is substantially normal to the upper chords of Long beams 8 run.
  • the upper ends of the side walls 10 communicate with each other, in the form of a roof 11, on.
  • the embodiment shown here has two upper belts 5a, b for each main crossbeam 2 on.
  • an air spring not shown in the drawing is provided under the lower flange 4, which exerts a pressure, thereby causing a bending load of the lower flange 4 is for locally increasing the plate rigidity in between the two upper chords 5a, 5b lying region of the main cross member 2, a further web 6b intended.
  • This is connected to the bottom flange 4, but with the bottom 2a of the floor profiles 2 not welded, since it exerts only a support function and only compressive forces receives.
  • diagonal infills 9 transmit the occurring Loads between upper flange 5 and lower flange 4, in particular shear stresses by occurring lateral forces.
  • the diagonal Infills 9 the function of the webs 6 of the main crossmember second
  • the invention allows even with a very small clearance between the upper edge of the bogie and the floor level of the rail vehicle the Attachment of continuous floor profiles 3, because of the position of the floor profiles 3 in the Region between the lower flange 4 and the upper chords 5a, 5b of the main cross member 2 his profile is increased to the height h and thereby the required bending stiffness is achieved, without that additional space below the floor profiles is required.
  • the webs 6a, 6c are each by an outer weld 14 with the bottom 3a of Floor profiles 3 connected, wherein the webs 6 a, 6 b, 6 c and the lower flange 4 easy and can be manufactured inexpensively from one piece.
