Definitions

  • the invention relates to a central buffer coupling for rail vehicles according to the preamble of claim 1.
  • the coupling head protrudes from the front of the vehicle profile.
  • Medium buffer couplings, the coupling head of which can be swiveled into the vehicle profile when not in use, are particularly suitable for rail vehicles that do not run on their own routes, eg tram vehicles in order to avoid endangering other precautionary participants by the coupling head protruding from the front of the rail vehicle.
  • the slot recess has a conical notch at each of its two ends, whereby the locking ring can be pressed into the one notch in the extended position of the two shaft parts and into the other raffia sink in the pivoted position of the shaft parts by means of the adjusting device.
  • the locking ring can be lifted out of the locking recess in question by the adjusting device.
  • the locking device is designed to be complex, since not only the locking bolt, the slot recess with the locking recesses and the locking ring are required, but also the adjusting device for the locking ring is formed from several individual parts, since on the one hand it axially displaces the locking ring on the Effect locking bolt and on the other hand, the locking ring must secure the locking ring in its position corresponding to the extended position of the two shaft parts.
  • a central buffer coupling in which a locking sleeve is provided as a locking device, which is mounted on the coupling shaft in the longitudinal direction and is displaceable in the extended position of the two shaft parts by the force of the springs in a locking position, in which the sliding sleeve for rigidifying the coupling shaft overlaps both shaft parts, a cam disc being connected non-rotatably to the two ends of the connecting bolt and having a cam surface which is eccentric to the axis of the connecting bolt and cooperating with the facing end face of the sliding sleeve, the cam discs form a stop for the sliding sleeve in its locking position and by pivoting the cams, the sliding sleeve can be moved against the force of the springs into an unlocking position which enables the front shaft part to pivot , in which the sliding sleeve can be fixed.
  • the invention has for its object to make a central buffer coupling of the type specified in terms of the design of the locking device with high functional reliability as simple as possible.
  • the coupling shaft of the central buffer coupling consists of a front shaft part 2 which carries the coupling head 1 and a rear shaft part 3 which is articulated horizontally on the underframe of the rail vehicle.
  • the front shaft part 2 is formed at the free end as a fork head 4 with an upper and lower fork leg, the fork legs receiving the rear shaft part 3 between them.
  • a connecting bolt 5 through fork head 4 and shaft part 3 the shaft parts 2 and 3 are connected to one another in such a way that the front shaft part 2 can be pivoted horizontally relative to the rear shaft part 3.
  • the bolt 7 is arranged in the vertical central longitudinal plane and is supported vertically by means of a holding plate 8 from the outside on the upper and lower fork legs by means of bolts 9 or bolts 9 and bushing 10.
  • the holding plates 8 are fastened via a fastening element (bolt 11) to one side of the vertical central longitudinal plane of the coupling shaft on the upper or lower fork leg.
  • the swivel angle is approximately 60 ° in the example.
  • the bolt 7 is connected by means of fastening element 22 to a sleeve 12, which is guided in the front shaft part 2, and in which a compression spring 13 is arranged, which is supported via a pressure piece 14 on the bottom of a spring chamber 15 located in the front shaft part 2 and through which Sleeve 12 is guided within the fork head 4 in the front shaft part 2.
  • the front shaft part 2 has a vertical groove 16, in which the bolt 7 can be displaced in and out of the groove 6 of the rear shaft part 3 to a limited extent for locking and unlocking.
  • the bolts 9 and bushes 10 are each guided in an elongated hole 17 in the holding plates 8.
  • a sleeve 23 is attached to each of the holding plates 8, into which a U-shaped actuating element (handle 18) is inserted with its free legs.
  • the handle 18 can be moved within the sleeves 23; it is secured against falling out by means of securing element 19.
  • the groove 6 is formed with a receptacle which widens towards the front and into which the correspondingly tapering bolt 7 can engage without play. In conjunction with the spring loading of the bolt 7, a play-free locking of the two shaft parts 2 and 3 against one another is thus achieved.
  • the rear shaft part 3 has, on the side of the vertical central length to which the front shaft part 2 can be pivoted, a run-on slope 20 against which the Bolt 7 comes into contact with the inserted position when pivoting from the pivoted position and on which the bolt 7 is slid backwards against the force of the compression spring 13 in the direction of the pressure piece 14 during pivoting. If the front and rear shaft parts 2 and 3 are in the stretched position, the swift Bolt 7 - loaded by the tension force of the compression spring 13 - in the groove 6 of the rear section 3 and locks the stretched position.
  • the fixing device is released by turning the handle 18.
  • the elongated holes 17 convert the rotary movement of the handle 18 or the holding plates 8 connected to it into a straight-line movement of the bolt 7 within the vertical groove 16.
  • the front shaft part 2 When the bolt 7 is disengaged from the groove 6, the front shaft part 2 can be pivoted about the connecting bolt 5.
  • a cover 21 is fastened to the front shaft part 2, which covers the groove 6 of the rear shaft part 3 in the pivoted position and protects it from dirt.
  • pivoting of the front shaft part 2 against the rear shaft part 3 is provided by approximately 150 °.
  • the entire central buffer coupling including the coupling head 1, can be swiveled in within the frontal boundary profile.
  • the front shaft part 2 can be swung in beyond the parallel position to the end face (FIG. 3).
  • the locking device with bolt 7 and groove 6 is arranged between the connecting bolt 5 and the coupling head 1.
  • the locking device with bolt 7 and groove 6 is arranged between the connecting bolt 5 for the shaft parts 2 and 3 and the articulation of the rear shaft part 3 on the rail vehicle.
  • the essential elements of the locking device in particular the spring-loaded bolt 7, are arranged at the free end of the rear shaft part 3; the correspondingly formed groove 6, on the other hand, at the end of the front shaft part 2 projecting from the connecting bolt 5.
  • the rear shaft part 3 is formed at the free end as a fork head 4 and now receives the front shaft part 2 between the fork legs.
  • the holding plates 8, sleeve 12, compression spring 13, pressure piece 14, spring chamber 15, run-up slope 20, cover 21 and vertical groove 16 are now assigned to the rear shaft part 3.
  • An arrangement of the locking device according to the second exemplary embodiment is advantageous if there is not enough installation space available on the shaft part 2 because of a short front shaft part 2.
