Definitions

  • the invention relates to a transition coupling for rail vehicles for coupling an automatic coupling of the Willison type with a manually operable hook coupling, the automatic coupling having a latch and a button in the area of a coupling mouth bordered laterally by rigid coupling claws and the hook coupling as coupling parts having a coupling hook and an eyelet part , wherein a coupling part corresponding to these coupling parts is held in a recess of the coupling head of the automatic coupling approximately to the side of the bolt and can protrude forward through the coupling mouth or is accessible from the front through the coupling mouth.
  • transition couplings are known for example from DE-PS 398 976 and DE-OSen 1 934 008 and 2 153 620.
  • the eye part designed in the manner of a dome chain with a turnbuckle is rotatably mounted about a horizontal cross bolt in the recess of the coupling head, in the unused state it hangs vertically downward from the coupling head and is only pivoted into a horizontal position in the operating state.
  • devices for the automatic coupling of pneumatic and / or electrical lines are often provided below the actual coupling head, which are located in the room which the eyelet hanging in the unused state also claimed for itself. It is therefore not possible to arrange both the mostly required line couplings and an upper clutch of the known type mentioned on an automatic coupling of the type mentioned.
  • the coupling bolt and possibly the coupling claw adjacent to it have a recess for the passage or accessibility of the coupling part, which is horizontally displaceable at most to a limited extent and is completely behind the coupling mouth in the uncoupled state .
  • the automatic clutch of the Willison type has a coupling head 1 which is provided on the end face with a coupling jaw 2, on one side of which there is a rigid, hook-like coupling claw 3 and on the other side of which there is a prismatic, rigid clutch claw 4 are.
  • the coupling head 1 can have, on the one hand, a conventional coupling horn 5 in its lower region and, on the other hand, an apron 6 interacting with it; between the coupling horn 5 and the apron 6, not shown, automatic line couplings of conventional design for the automatic coupling of air and / or electrical lines can be provided.
  • the clutch corresponds to a conventional Willison clutch.
  • the coupling head 1 is provided with a recess 9 which is open towards the front in the region of the coupling jaw 2.
  • the bolt 7 has a recess 10 in its front section, which corresponds to the recess 9 and is therefore also located in the middle vertical extent of the bolt 7.
  • the coupling claw 4 likewise has a recess 11 corresponding to the recess 9 in the region of its central height extent. According to FIG. 3, in the recesses 9, 10 and 11, which are wide open towards the front, there is an eyelet part 12 serving as a coupling part of a manual coupling.
  • the eyelet 13 of the eyelet part 12 is located at its front end and in the rest position shown, just behind the coupling mouth 2 inside of the recesses 9, 10 and 11.
  • the eyelet 13 is followed by a strong shaft part 14 which extends backwards approximately in the longitudinal direction of the coupling head 1 and is dimensioned such that it is able to transmit the coupling tensile forces.
  • the shaft part 14 merges on an annular flange 15 into a much weaker shaft part 16, which extends rearward in the extension of the shaft part 14 and ends with a spring plate 17. In the rest position shown, the spring plate 17 is located near the rear end of the recess 9.
  • the ring flange 15 is with a stop surface 18 facing the coupling mouth 2.
  • the recess 9 is provided with an inner flange ring 19, which is penetrated with play by the shaft part 14, on which a spring 20, which on the other hand rests on the spring plate 17, is supported and which has a stop surface 21 on the back, which together with the stop surface 18 forms a stop 18,21.
  • the spring 20 is biased so that it can pull the eyelet 12 into the rest position shown and hold it in this position; on the other hand, the spring 20 is so weak that it can be overcome by hand.
  • the eyelet part 12 In the idle state of the transition coupling, the eyelet part 12 assumes the position shown in FIG. 3, in which it is completely retracted into the recess 9 by the spring 20 and its eyelet 13 is located closely behind the coupling mouth 2.
  • the eyelet part 12 For mixed coupling, the eyelet part 12 must be partially pulled out of the coupling head 1 by hand, in particular with its eyelet 13 passing through the recesses 10 and 11. The eyelet 13 can then be hooked into the coupling hook of the vehicle to be coupled, which has a hook hand coupling.
  • the stop surface 18 of the ring flange 15 at least almost comes to rest against the stop surface 21 of the inner flange ring 19; in the event of a subsequent tensile load in the mixed coupled state, the tensile force is transmitted by the closed stop 18, 21 from the eyelet part 12 to the coupling head 1 or vice versa.
  • the power transmission takes place in the longitudinal direction of the coupling head 1, so that only when cornering the coupling head 1 is slightly deflected by its usual articulation joint shown at 22 in the vehicle.
  • the pressure forces are to be transmitted through the side buffers of the coupled vehicles, as is common with transition couplings.
  • the eyelet part 12 in the coupling head 1 Coupling hooks as a coupling part, rigidly behind the coupling mouth 2 in the recess 9, or at the most to be able to be pulled out so as to be able to be pulled out for short strokes.
  • the coupling chain of the other vehicle is to be hooked into the coupling hook, the recesses 10 and 11 making the hooking-in process considerably easier.
  • the transition coupling inevitably has a longitudinal play after it has been coupled, that is to say it is not tightly tensioned in the case of adjacent side buffers, which can result in an uneven driving behavior of a train set.
  • the transition coupling can be equipped with the stop device shown in FIGS. 4 and 5. 4 and 5, the eyelet part 12 is shown with the eyelet 13 and the shaft part 14, the shaft part 16 with the spring plate 17 and the spring 20 are omitted for simplicity.
  • the ring flange 15 has on its side facing away from the abutment surface 18 a wedge surface 23 penetrated by the shaft part, which in the illustrated, playful mixed coupling state is offset by a wedge surface 24 of an intermediate part 25 offset to the rear.
  • the intermediate part 25 is mounted in the coupling head 1 so as to be displaceable in relation to the eyelet part 12, whereby it is supported at the front by strong guides 26.
  • the intermediate part 25 is forked and encompasses the shaft part of the eyelet part 12; a spring 27 holds it in the position shown, by hand it can be moved from this position to the side against the force of the spring 27 by means of a handle 28, so that it emerges from the path of movement of the ring flange 15.
  • the back of the intermediate part 25 is formed into a stop surface 29.
  • the eyelet part 12 is pushed back by a short, weak pressure load on the transition coupling, the wedge surfaces 23 and 24 come into engagement and the intermediate part 25 is pressed to the side against the force of the spring 27.
  • the ring flange 15 can then slide past the intermediate part 25 backwards, whereupon the intermediate part snaps back into the position shown under the force of the spring 27.
  • the eyelet 13 has reached a set-back position.
  • the stop surface 18 is now no longer opposite the stop surface 21 but the stop surface 29, with a subsequent tensile load the tensile forces are thus transmitted from the eyelet part 12 via the stop surfaces 18 and 29 as well as the intermediate part 25 and the guides 26 to the coupling head 1. Due to the aforementioned, recessed position of the eyelet 13, the game in the coupled transition coupling is eliminated, so that a smooth, shock-free travel of the train set is possible.
  • the eyelet part 12 For mixed coupling, starting from the idle state, the eyelet part 12 must be moved to the position shown in FIG. 4 by means of a handle indicated by the reference numeral 30 with simultaneous manual displacement of the intermediate part 25, whereupon the eyelet 13 can be easily inserted into the coupling hook the hook coupling is to be attached.
  • the intermediate part 25 When the intermediate part 25 is released, the spring 27 presses it into the position shown, so that the mixed coupling state with play is reached.
  • After the release of the eyelet part 12 After the release of the eyelet part 12, it returns to its rest position under the force of the spring 20 with a brief lateral deflection of the intermediate part 25.
  • a bolt 31 which is displaceable in the longitudinal direction of the coupling and is offset to the side with respect to the eyelet part 12.
  • the latch 31 can by a handle 32 can be pushed forward manually against the force of a spring 33 with the intermediate part 25 deflected to the side, whereby it hooks with an inclined holding surface 34 against a corresponding counter surface 35 on an undercut of the intermediate part 25.
  • the intermediate part 25 is released, it is held in its deflected position by the bolt 31, the inclined arrangements of the holding surface 34 and counter surface 35 likewise holding the bolt 31 in its pressed-in position.
  • the intermediate part 25 is thus held in its inactive position and the coupling tensile forces can only be transmitted from the eyelet part 12 to the coupling head 1 via the stop 18, 21.
  • the clutch play cannot be switched off automatically. Only when the bolt 31 is pulled out manually into the position shown or with a short, additional, lateral deflection of the intermediate part 25, in which the holding surface 34 and the counter surface 35 disengage and the bolt 31 thus automatically under the force of the spring 33 into the snaps back position shown, the intermediate part 25 is free again and the spring 27 pushes it as a result in the position shown. Only then can a clutch play be switched off again automatically.
  • the latch 31 is therefore designed to be self-locking only under load.
  • a hook part 36 can also be provided instead of the eyelet part 12, as indicated in FIGS. 6 and 7.
  • the stop device shown in FIGS. 4 and 5 thus adjoins the shaft 37 of the hook part 36 shown broken off.
  • the intermediate part 25 can be displaceable in any direction, not only as can be seen in the exemplary embodiment, in the horizontal direction transverse to the longitudinal direction of the eyelet part 12.
  • the recess 11 can be omitted if the transition coupling is narrow, if the recesses 9 and 10 are sufficient for the passage or accessibility of the eyelet or hook part.
  • the transition coupling for rail vehicles for coupling an automatic Willison-type coupling with a manually operable hook coupling has an eyelet part 12 or hook part which is mounted in the coupling head 1 in a longitudinally shiftable manner.
  • the eyelet part 12 is located in a recess 9 of the coupling head 1, which opens into the coupling mouth 2.
  • the bolt and a coupling claw 4 of the coupling head 1 are also provided with recesses 11 through which the eyelet part 12 is freely accessible. Contrary to the force of a spring 20, the eyelet part 12 can be manually pulled out of the recess 9 through the coupling mouth 2 to the front and hooked into the hook of a hook coupling. The pulling out is limited by a stop 18, 21 transmitting the coupling tensile forces.
  • a stop device can be provided which, in the mixed-coupled state, engages automatically when the eyelet part 12 is initially pushed back and switches off the coupling play of the transition coupling.
  • transition coupling results in a straight-line traction transfer between the coupled vehicles, it does not hinder the attachment of conventional cable couplings to the coupling head 1.
