Definitions

  • the invention relates to an automatic central buffer coupling for a rail vehicle with a pulling and pushing device which is connected to the underframe of the rail vehicle and has a deformation element.
  • the pulling and pushing devices of such automatic center buffer couplings serve to introduce the usual forces occurring in driving and maneuvering operation elastically into the undercarriage of the rail vehicle with a predeterminable damping.
  • These traction and impact devices are suitable for absorbing the impact energy up to an impact speed of approximately 13 km / h.
  • the deformation element serves to destroy the impact energy generated at impact speeds of more than 13 km / h by the deformation work of the deformation element. After such a shock, the central buffer coupling with the pulling and pushing device must be removed to replace the deformation element.
  • the deformation element preferably consists of a deformation tube which projects with a conical end into a corresponding tapered bore in a nozzle plate.
  • the invention has for its object to provide an automatic central buffer coupling, which is able to absorb overruns by deforming a deformation tube and can be attached to the underframe of a rail vehicle with simple design means.
  • the bearing block rests on a fastening element of the base frame, so that the tensile and impact forces from the bearing block are introduced directly into the base frame.
  • the bearing block with the deformation tube only moves relative to the undercarriage of the rail vehicle when an overlap causes the deformation tube to deform and to the nozzle plate, the screw connection serving as a sliding guide for the bearing block.
  • the automatic center buffer coupling according to the invention therefore does not require any complex, precisely machined guide strips, since their role is taken over by the screw connection in the event of the deformation of the deformation tube due to an overlap.
  • the bearing block can preferably consist of a first, rigidly screwed to the base frame, an opening for the passage of the pulling and pushing device, and a second, connected to the pulling and pushing device, screwed to the deformation tube and the nozzle plate, when the deformation tube deforms relative to the first bearing block part of the nozzle plate movable bearing block part.
  • the automatic center buffer coupling with the pulling and pushing device, the two bearing block parts, the deformation tube and the nozzle plate can be preassembled and then only needs to be screwed onto the underframe of the rail vehicle by means of the first bearing block part.
  • a possible one-piece design of the bearing block requires the mounting of the bearing block with the deformation tube and the nozzle plate with the aid of the screw connection on the underframe of the rail vehicle, which, however, requires a somewhat higher assembly effort.
  • the first bearing block part can consist of parallel strips which are screwed vertically to the base frame and which are screwed beforehand to the second bearing block part, the deformation tube and the nozzle plate.
  • the screw connection can consist of four tension screws arranged in a rectangle and clamped between the first bearing block part and the nozzle plate, which reach through the second bearing block part and form the bearing block guide when the deformation tube is deformed.
  • the bearing block or the second bearing block part can consist of a bearing plate with legs bent laterally forwards and having holes for the screw connection and fastening tabs for the pulling and pushing device.
  • the deformation tube is supported during tensioning with one end on the bearing plate and with its tapered other end in the corresponding tapered bore in the nozzle plate and is axially tensioned by means of the screw connection.
  • a central buffer coupling 1 is connected to a pulling and pushing device 2, which the pulling and pushing forces occurring in normal driving operation, for. B. on ring spring elements, energy consuming and elastic.
  • the pulling and pushing device 2 is pivotally attached to a bearing block 5, 6 by means of a pivot pin 4.
  • Two obliquely arranged damper-spring elements 3 cause the central buffer coupling 1 to be reset when deflected from its axial position in the vertical and horizontal directions.
  • the bearing block 5, 6 consists of a first bearing block part 5 in the form of parallel spaced strips which are screwed to the base frame of a rail vehicle, not shown, with fastening flanges 10.
  • a second bearing block part 6 is screwed to the first bearing block part 5 and consists of a bearing plate 7 with lateral legs 8 bent forward at right angles. Furthermore, the bearing plate 7 has upper and lower tabs 9, which are directed towards the front and serve to fasten the pulling and pushing device 3 by means of the pivot pin 4.
  • a deformation tube 11 bears on the bearing plate 7 with its front end. This deformation tube 11 has a tapered end which projects into a corresponding tapered bore in a nozzle plate 12.
  • the first bearing block part 5, the second bearing block part 6, the deformation tube 11 and the nozzle plate 12 are axially braced against one another by means of four tension screws 13 arranged in a rectangle.
  • This unit together with the pivotable central buffer coupling and the pulling and pushing device 2 can be pre-assembled on the mounting flanges 10 of the rail vehicle underframe. If a collision occurs, for example, at more than 13 km / h, the second bracket part 6 drives the deformation tube 11 through the bore in the nozzle plate 12 with a reduction in diameter, as a result of which the impact energy is converted into deformation work of the deformation tube 11. The second bracket part 6 moves and is guided by the lag screws 13. Additional guidance on the rail vehicle undercarriage is unnecessary. Of course, the deformation tube 11, if it has been deformed due to an impact, must be replaced so that the rail vehicle is ready to run again.
  • a one-piece form can also be provided, in which only the second bearing block part 6 is present.
  • the front of the legs 8 is screwed directly to the mounting flanges 10, however, a preassembly of the bearing block part 6 with the deformation tube 11 and the nozzle plate 12 is not possible, since in this case the lag screws 13 are simultaneously used as mounting screws on the mounting flanges 10 of the rail vehicle undercarriage serve.
  • the deformation path of the deformation tube 11 can be practically doubled compared to the known design, which means that overruns can be absorbed at higher speeds without damage or that lower deceleration forces occur at the same speed .
