Definitions

  • the invention relates to a mounting interface for attaching load-bearing components to a buffer of a rail vehicle, in particular steps, steps, handles and/or stands, preferably in the front area.
  • the invention includes a buffer system, e.g. a shock device made up of a crash element and center flange buffer, with such a mounting interface, e.g.
  • the relevant interfaces for mounting the front assembly are usually located on the front panel of the underframe of the rail vehicle.
  • holder constructions that protrude forwards have hitherto been attached to the front panel, but these have the disadvantage that they require or have a large amount of space.
  • ascents, handles or steps there is also the fact that their fastenings must be dimensioned in such a way that they do not deform plastically and only to a small extent elastically during use.
  • Stands, steps, handles or steps are usually fastened on one side of the car body. Depending on the required tread width or depth, the fastenings must then be dimensioned accordingly to ensure a low elastic deformation.
  • a massive and overhanging attachment leads to increased weight and possibly. due to poor accessibility to increased installation effort, which is a disadvantage.
  • crash elements also referred to as “deformation elements” or “energy absorption elements”.
  • this conversion occurs through an irreversible deformation of the crash elements, which fold axially.
  • a mounting interface according to the invention for attaching load-bearing components to a buffer of a rail vehicle comprises a mounting body with a component fastening area and a different attachment area.
  • the mounting body of the mounting interface which basically also represents the mounting interface itself, therefore comprises two different areas, one of which is used to attach the supporting components and the other to attach the mounting interface to the buffer.
  • load-bearing components means components that are intended to be attached to one end of a rail vehicle and can carry a load, in particular steps, steps, handles, stands or brackets.
  • the component attachment area is equipped with attachment elements and/or holes for attaching the relevant load-bearing components for the rail vehicle.
  • Fastening elements are preferably bolts or screws that are already firmly attached to the holder body. Holes are preferably already tapped so that a component can easily be screwed onto the bracket body without necessarily using a nut (although one can of course also be used for securing).
  • the attachment area is shaped in such a way that it can be fastened (in particular at at least three fastening points) to the rear of a buffer flange with buffer screws (typically commercially available screws), in particular with four screws.
  • buffer screws typically commercially available screws
  • it has the same shape as the buffer flange and has holes in the corresponding places like the buffer flange so that it can be fixed together with the buffer flange using the buffer screws.
  • the attachment area may have a central recess so that it can include a bumper housing (i.e., a bumper sleeve or plunger) on the bumper flange (e.g., advantageous with a center flange bumper).
  • a bumper housing i.e., a bumper sleeve or plunger
  • the bumper flange e.g., advantageous with a center flange bumper
  • a buffer flange (often also referred to as “buffer (foundation) plate”) is the plate with which a buffer is intended to be attached to a rail vehicle or a crash element.
  • the buffer flange is attached to the buffer beam of a rail vehicle or to a crash element by screwing the components together using so-called “buffer screws”. Buffers on a rail vehicle (or on a crash element).
  • end flange buffers and middle flange buffers.
  • End flanges are attached to the end of a buffer sleeve and center flanges are pushed onto a buffer housing, in particular its buffer sleeve, and attached in particular in the area of its center.
  • the existing interface between the crash element or buffer beam and buffer can be used to generate further interfaces for additional attachments, but the buffer can also be extended forward.
  • a buffer system according to the invention comprises a buffer, preferably a center flange buffer, with a buffer flange and a mounting interface according to the invention attached to this buffer flange with buffer screws.
  • the buffer system preferably also includes a crash element which is attached to the buffer flange by means of buffer screws.
  • the mounting interface is preferably attached between the crash element and the buffer flange.
  • a rail vehicle according to the invention comprises a buffer system according to the invention.
  • the rail vehicle is preferably a locomotive, in particular for shunting purposes, or a wagon.
  • the invention has the particular advantage that an interface for attaching components or attachments to a rail vehicle is made possible, which extend far forward in the longitudinal direction of the vehicle or are to be positioned there. A certain variability is also provided by an appropriate design of the fastening elements, so that the rail vehicle can be converted.
  • the adjustment effort and thus the assembly effort can be further reduced by a more favorable tolerance chain due to a reduced number of components subject to tolerances within the tolerance chain.
  • the attachment area has the same shape as a predetermined buffer flange or at least a part of this buffer flange and can be fastened together with the buffer flange by means of predetermined buffer screws. This has the advantage that simple assembly and disassembly (e.g. to replace it with a different mounting interface) is possible. A detachable fastening of the mounting interface, for example by means of the buffer screws, is very advantageous.
  • the attachment portion is recessed (e.g., a hole) so that it may enclose a bumper housing (i.e., bumper sleeve or bumper plunger) of a predetermined bumper.
  • a bumper housing i.e., bumper sleeve or bumper plunger
  • the attachment area preferably corresponds to only part of the surface of a buffer flange of a predetermined buffer and includes at least three holes for the buffer screws. It preferably has a recess where a buffer housing is located on the buffer flange.
  • the attachment area is angled, preferably perpendicular, relative to the component attachment area. This is used to attach a step, e.g. a horizontal standing surface, e.g. a maintenance stand.
  • a fastener is a bolt or screw and is fixedly attached to the bracket body in the component attachment area.
  • a fastener a hole in the component
  • Fastening area which is in particular provided with a thread.
  • a preferred embodiment of the mounting interface includes in the component mounting area mounting elements or holes designed for attaching additional attachments.
  • additional attachments are preferably a coupler handle, a shunter step, a shunter stand, a maintenance stand, a railing and/or a handrail.
  • the mounting body is shaped in such a way that it has at least one (structural) weakening of the mounting body between the component fastening area and the attachment area.
  • This weakening is designed in such a way that when a predetermined force acts on the weakening, the component fastening area separates from the attachment area.
  • the weakening is preferably a predetermined breaking point, in particular in the form of a perforation or a shearing element.
  • the attachment of load-bearing components e .g . B. of handles or steps, fail on the buffer-side of the crash element in an accident. This is achieved by said weakening z. B. a targeted weakening of the load-bearing cross-sectional area of the holder body.
  • a preferred embodiment of the buffer system includes a crash element which is attached to the buffer flange by means of buffer screws.
  • the mounting interface is attached between the crash element and the buffer flange.
  • the buffer is a center flange buffer.
  • the attachment area of the mounting interface has the same shape as the buffer flange (at least the contour, or possibly plus a recess in the inner area) and has holes at the corresponding points like the buffer flange.
  • the mounting interface is preferably fastened to the buffer flange by means of the buffer screws, in particular between a crash element and the buffer flange.
  • the mounting portion of the mounting interface is recessed to at least partially encompass a bumper housing (i.e., bumper sleeve or bumper ram), which is particularly advantageous for attachment to mid-flange bumpers.
  • the attachment area preferably corresponds to at least part of the area of the buffer flange, in particular its area minus the recess, and the mounting interface is fastened to the buffer flange with at least three buffer screws.
  • FIG. 2 an attachment of load-bearing components in the area of a buffer of a rail vehicle according to the prior art
  • FIG. 4 shows an exemplary embodiment of a buffer system according to the invention with a preferred mounting interface
  • FIG. 5 shows a further exemplary embodiment of a buffer system according to the invention with an angled component fastening area and a perforation.
  • FIG. 1 shows a buffer 10 according to the prior art.
  • the buffer has a buffer flange 11, which can also be referred to as a "buffer base plate” and is used to attach the buffer 10 to a buffer beam of a rail vehicle 4 or, as shown here, to a crash element 3.
  • the buffer flange 11 is attached by means of buffer screws 12, only one of which is shown here in order to also show the holes that are present in the buffer flange 11 and the crash element 3 for this purpose.
  • the buffer sleeve 13, into which the buffer tappet 14 protrudes, is welded to the buffer flange 11 here.
  • An elastic buffer element (not visible here) is introduced between these two elements, which can reversibly absorb and release pressures acting on the buffer plate 15, whereby it can preferably also convert some of the energy into heat and thus serve as a shock absorber.
  • the crash element 3 serves to increase this. It deforms in the process and acts as a crumple zone.
  • FIGS. 2 and 3 show how load-bearing components 2 are attached to a buffer 10 of a rail vehicle 4 according to the prior art.
  • the arrows point to those areas of the rail vehicle 4 to which the load-bearing components 2 are attached.
  • a step 2 is used here as an example of a load-bearing component 2 . But it could also be a handle or a shunter's stand.
  • the step 2 shown here is fastened in the front area of the rail vehicle 4 .
  • the step 2 is fastened to the front panel of the underframe of the rail vehicle and to its side of the car body, as indicated here in more detail by the arrows. Due to the rather large tread width, the fastenings are comparatively massively dimensioned in order to ensure low elastic deformation.
  • FIG. 4 shows a preferred buffer system 9 with an exemplary embodiment of a mounting interface 1 according to the invention, to which a step 2 or a handle is attached as a supporting component 2 .
  • the buffer system 9 includes a buffer 10 with a buffer flange 11 which is mounted on a crash element 3 as z. B. is shown in Figure 1 .

  • the mount interface 1 here has a mount body 1 (and basically consists of this mount body 1 in this example).
  • This mounting body 1 has two separate component mounting areas here la, an upper and a lower one, on which the kick 2 is attached.
  • the attachment area 1b which has the same shape as the buffer flange 11 here, is located between these component attachment areas la.
  • the component fastening area 1a is equipped here with holes 5 (of which only one is provided with a reference sign for the sake of clarity), it also being possible for screws to be present in the component fastening area 1a instead of the holes 5.
  • the attachment area 1b can be fastened here with all four buffer screws 12 between the crash element 3 and the buffer flange 11, so that these buffer screws 12 connect the crash element 3 and the buffer flange 11 to the bracket interface 1 in between to form the buffer system 9.
  • FIG. 5 shows another exemplary embodiment of a buffer system 9 according to the invention, corresponding to FIG.
