Definitions

  • the invention relates to a coupling arrangement for rail vehicles, in particular shunting locomotives.
  • both center buffer clutches are swiveled up using the lifting cylinder, the upper coupling being locked in the upper position then reached, while the other coupling is lowered again using the lifting cylinder, so that the towing hook is released.
  • the lower central buffer coupling If the lower central buffer coupling is to be used, it can be pivoted into its operating position with the aid of the lifting cylinder, the upper central buffer coupling being able to remain in the locking position. If the upper middle buffer coupling is to be used, it is released from its lock and pivoted into its operating position with the aid of the lifting cylinder.
  • the lifting cylinder allows remote-controlled switching between the two clutches.
  • each central buffer coupling has two mutually parallel drive rods which are arranged on both sides of the carrier and are connected via a connecting bolt which extends through the elongated hole.
  • An off-center rod is also possible.
  • the piston rod of the lifting cylinder engages at least on one of the cross bolts. Both cross bolts can be moved independently of each other in the slot.
  • the ends of the drive rods of a central buffer coupling can be connected via a roller that is on a track for the rollers trained side of the carrier rolls, the roller is connected to the associated cross bolt via driver bracket.
  • This has the advantage that only pressure forces are transmitted to the drive linkage. Lifting movements applied from the outside, for example by deflecting the corresponding central buffer coupling during operation, cause the roller to lift off its track. Downward movements are absorbed by springs in the drive rods.
  • the locking device is preferably arranged on the carrier for the lifting cylinder. It has a pivoted locking lever and an associated pivoted pawl.
  • the locking lever has a projection protruding into the adjustment path of the cross bolts and a nose which interacts with the pawl.
  • the projection serves on the one hand to pivot the locking lever out of its rest position when a cross bolt hits the projection, and on the other hand to undercut the cross bolt when it has passed the projection and the locking lever falls back into its rest position, and thus the associated center buffer coupling lock in the position reached.
  • the nose of the locking lever cooperates with the pawl in such a way that it can both overlap and underneath the pawl.
  • the pawl can have a stop projecting into the travel of the cross pin, which limits the travel of the cross pin when the nose of the locking lever covers the pawl.
  • the carrier can have a stop for the locking lever and / or the pawl.
  • the locking lever and the pawl can be designed so that they fall back into their respective rest position by weight forces. But they can also be spring-loaded.
  • a remote control This can be a cable, a chain or an automatic remote control.
  • the coupling arrangement shown includes a connecting rod 1 which is connected to the shunting locomotive and which has a pulling hook 2 at its free end.
  • a connecting rod 1 which is connected to the shunting locomotive and which has a pulling hook 2 at its free end.
  • two different couplings 4, 5 are pivotally mounted in a joint 3 with a horizontal joint axis via associated connecting parts 6, 7.
  • the clutch 4 is a conventional shunting clutch.
  • the clutch 5 is of a different type; preferably a center buffer coupling or an automatic train coupling.
  • a carrier 8 is fastened to the pull rod 1 and, in the embodiment shown, extends downward and in the direction of the shunting locomotive, not shown.
  • a lifting cylinder 9 At the lower end of the carrier 8 there is a lifting cylinder 9, the piston rod 10 of which projects into an elongated hole 11 of the carrier 8.
  • the elongated hole 11 extends over a larger section of the beam length.
  • two cross bolts 12, 13 are guided, which are independent of each other.
  • parallel drive rods 14 are connected on one side or on both sides, which extend laterally of the support 8 and which are connected in an articulated manner to the connecting part 6 of the central buffer coupling 4.
  • entraining brackets 15 are connected on one side or on both sides, between which at the other ends one or more rollers 16 are mounted, which roll on a contour of the carrier 8 designed as a raceway 17.
  • Drive rods 18, which are connected in an articulated manner to the connecting part 7 of the coupling 5, are in turn connected to the rollers 16 on one side or on both sides.
  • a locking device 19 is also arranged on the carrier 8, which is only indicated in FIG. 1 and the details of which are shown in FIGS. 2 to 4.
  • the locking device 19 includes a locking lever 21 mounted in a pivot bearing 20 on the right next to the elongated hole 11 on the carrier 8 and a pawl 23 mounted in a pivot bearing 22 on the left next to the elongated hole 11 on the carrier 8.
  • An abutment 24 arranged on the carrier 8 serves as a stop for both the locking lever 21 and for the pawl 23.
  • mirror-image designs are also possible.
  • the locking lever 21 has a protrusion 25 of approximately half its length, which extends when the locking lever 21 rests on the abutment 24 into the travel of the cross pin 12.
  • a nose 26 which is connected to the pawl 23 cooperates, the contours of the nose 26 on the one hand and the pawl 23 on the other hand are designed so that the pawl 23 can be covered over and under the nose 26.
  • the locking lever 21 includes an actuating arm 27 which has a connection device 28 for remote actuation, not shown.
  • the remote control can be a pull rope, a pull chain or a remote control with a separate drive.
  • the locking lever 21 and the pawl 23 are designed and arranged in the illustrated embodiment so that they fall back towards the abutment 24 without external force. This does not exclude that additional springs that support this movement are arranged.
  • the clutch arrangement shown works as follows: starting from the basic position shown in FIG. 1, in which the clutch 4 is in the operating position, that is to say essentially in the horizontal position, and the clutch 5 is pivoted downward, the piston rod 10 of the lifting cylinder 9 is retracted and the two cross bolts 12, 13 are located at the lower end of the elongated hole 11, the coupling 5 is to be pivoted into the operating position.
  • the lifting cylinder 9 is actuated, the piston rod 10 of which extends and the two transverse bolts 12, 13 are displaced into the area of the locking device 19.
  • the shunting coupling 4 is pivoted upwards and the coupling 5 is pivoted in the operating position, that is to say in an essentially horizontal position.
  • the locking lever 21 is pivoted with a force acting on the actuating arm into the position shown in FIG. 2, in which its projection 25 is outside the travel range of the cross bolts 12, 13.
  • the cross bolts 12, 13 first strike a stop surface 29 of the pawl 23. This state is shown in FIG. 2.
  • the transverse bolts 12, 13 are moved further in the elongated hole 11, pivoting the pawl 23 into a position which is shown in FIG. 3. In this position, the projection 25 of the locking lever 21 is located between the cross pin 12 and the cross pin 13 and the nose 26 of the locking lever 21 is below the pawl 23.
  • the lifting cylinder 9 is actuated so that the piston rod extends while taking the transverse pin 13 with it, and initially swivels the coupling 5 upwards.
  • the locking lever 21 can be pivoted so far by a force acting on its actuating arm 27 that its projection 25 comes free from the cross pin 12 and the pawl 23 the nose 26 of the locking lever 21 can happen.
  • the locking lever 21 then falls against the pawl 23 supported on the abutment 24 and assumes the position shown in FIG. 4. If the lifting cylinder 9 is now relieved, the cross bolts 12 and 13 move to the lower end of the elongated hole 11 and the couplings 4, 5 again assume the position shown in FIG. 1.
