Definitions

  • the invention relates to a head support for side buffers, in particular for rail vehicles, with struts connected thereto for transmitting the buffer forces into the underframe of the vehicle.
  • the invention proceeds from the state of the above Technology from and it is based on the task of eliminating the shortcomings identified, in particular thus creating a head support in which the connection between head support and struts is easier and cheaper to carry out, this connection being designed in the sense of a perfect flow of force and sufficient stability should be.
  • the head girder to be created in this connection point should be usable for a large number of vehicle types (e.g. tank wagons, covered goods wagons) which are equipped with buffers of the same connection dimensions and the same stress conditions.
  • This object is achieved in that an element is used in the head support for attaching the side buffer, which is designed to absorb the forces occurring during driving and has connecting pieces for the struts for the transmission of these forces into the base frame.
  • an embodiment of the invention provides that the element consists of a prefabricated, preferably rectangular plate with the connecting pieces for the struts attached to it.
  • a particularly favorable design in terms of weight of the element which corresponds to the stability and connection requirements, is provided in that the connecting pieces are arranged with a tubular attachment on and on the plate of the element in the longitudinal center of the side buffer and facing away from it Plate connected ribs are formed.
  • the spring pillar thus formed is supported against its force via annular flanges by so-called preload pots holding the ready-to-install spring pillar on the buffer tappet and on the base plate of the buffer housing; in the case of a buffer joint, the surface of this flange transfers the buffer force indirectly to the head carrier.
  • the cross section of the tubular extension is designed in accordance with the force transmission surface of a spring lying within the side buffer, which acts indirectly on this extension.
  • another embodiment of the invention provides that the surface of the plate enclosed by the tubular extension has a dome-shaped recess. This measure also involves a reduction in weight.
  • the connecting pieces in particular the ribs, have anti-rotation contact surfaces for hexagon bodies located on the rear of the plate of the element - screw head or nut - of the fastening screws for the side buffer.
  • This design makes assembly / disassembly of the side buffer much easier; the otherwise necessary holding of the screw head or nut by means of an additional wrench in a relatively inaccessible place is eliminated.
  • the forces that occur when loosening high-strength screws, possibly secured by a two-component adhesive, are also absorbed in a simple manner via the contact surfaces.
  • the element a simple and cheap oil production as well as a smooth flow of force according to a further idea of the invention is achieved in that the element is formed in one piece (for example by forging, casting). Such a one-piece design is optimal because of the possible rounded cross-sectional transitions in terms of power flow and strength.
  • a cost-effective, rich support for the base plate of the buffer housing on the element is achieved according to a further feature of the invention in that the surface of the element facing the base plate of the buffer housing has a raised, the surface of the base plate corresponding processing approach.
  • the use of high-strength, pre-tensioned screws is possible due to the full support;
  • the resulting, to a greater extent, effective surface pressure between the element and the base plate of the buffer housing results in a better transmission of the transverse forces that occur during operation.
  • the element 3 used in the head support 1 and formed as a single piece and made as a forging or casting consists of a rectangular plate 3a with the connecting pieces 4 thereon for the struts 5 shown in FIGS. 4 and 5.
  • the plate 3a is welded at its circumferential edges 3f to the web la of the head support 1, the over to these edges, swung to the full panel thickness, in accordance with the existing stress.
  • the surface 3d of the element 3 facing the base plate 2a of the buffer housing has a raised surface , the surface of this base plate 2a corresponding machining approach 3e.
  • a tubular extension 4a is arranged in the longitudinal center of the side buffer 2 and facing away from it on the plate 3a; this approach forms, together with ribs 4b arranged above and below and in each case centrally to the approach 4a, transverse to the longitudinal center of the side buffer 2, the connecting pieces 4 for the struts 5.
  • the surface 3b of the plate 3a enclosed by the tubular approach has a dome-shaped recess 3c on. The forces which occur during the buffer stroke and are introduced into the buffer spring are transmitted to the element 3 via the base plate 2a of the buffer housing and from there are transmitted essentially into the long beams 6 via the connecting pieces 4 and the struts 5 connected therewith.
  • these carriers can be arranged on the outside, at the ends of the head carriers 1, and according to FIG. 5 in the region of the longitudinal center line of the vehicle.
  • the attachments 7 connected to the head supports 1 in both figures serve to accommodate spring mechanisms for an automatic central buffer coupling, the attachments 7 also being connected to the connecting pieces 4 of the elements 3 by means of supports 7a welded to the underframe according to FIG.
  • the contact surfaces 4c are each designed to prevent rotation for a hexagon body 8a, here the screw head, of the fastening screws 8 of the side buffer 2. This makes it unnecessary to hold these screw heads with a corresponding wrench when installing or removing the side buffer 2.
