Definitions

  • the invention relates to an automatic coupling for rail vehicles, with a coupling head designed in particular as a rigidly coupling Willison coupling head and with a cable coupling with a protruding, elastically push-back and pneumatic coupling forward in the coupling state, in the pressing direction against a countercurrent coupling head, loaded cable coupling head.
  • Such a coupling is known from DE-OS 2 022 201.
  • DE-OS 1 937 880 shows a similar coupling with a projecting, resiliently retractable line coupling head.
  • the line coupling head In couplings of the type mentioned at the outset, the line coupling head must be able to be pushed back relatively far against spring force in order to ensure that during coupling and uncoupling operations the line coupling head does not have parts of the counter coupling is damaged.
  • DE-OS 1 605 175 it is known, in order to avoid such damage, not only to retract the line coupling head against spring force, but also to deflect it to the side.
  • OS 1 605 166 or a short-stroke cylinder coupled to a forward pivoting lever, which frictionally locks the line coupling head to prevent it from running back, can be used.
  • these known arrangements can only be used in the presence of the aforementioned feed gear, which can be actuated as a function of a mating clutch, and cannot be transferred to couplings of the type mentioned at the outset with the above, elastically push-back line coupling head.
  • an automatic clutch of the type mentioned by a short-stroke cylinder having a cylinder body and a piston the one part - cylinder body or piston - is coupled to the line coupling head, such that this part exerts a forward force on the line coupling head when pressure is applied to the short-stroke cylinder, and the other part - piston or cylinder body - is mounted so as to be relatively displaceable to the coupling head and to the line coupling head, and further by a locking mechanism which is locked against spring force only when the short-stroke cylinder is pressurized and which is arranged between the other part and the coupling head and which, in its latching position, locks the other part in a position relative to the coupling head against backward movement, in which position the one Part is with coupled line coupling head near its front end position relative to the other part.
  • a line coupling head 1 is shown, which is provided with a rearward projecting line pipe 2.
  • the line coupling head 1 with line pipe 2 is held in a coupling head, preferably a rigidly coupling Willison coupling head, which is displaceable in the direction of the longitudinal axis 3 via a guide, not shown, a spring also not shown loads it in the direction of arrow 4, ie in the direction of displacement forward.
  • the pipe to be coupled, not shown, of the rail vehicle is connected to the pipe 2 by means of a sealed telescopic guide, a hose adapter or the like. movably coupled.
  • a short-stroke cylinder 5 In any direction next to the conduit 2, preferably below the conduit 2, there is a short-stroke cylinder 5 with a piston 6 and a cylinder body 7.
  • the piston 6 carries a piston rod 8 projecting forward in the direction of the arrow 4, the end of which on a on the conduit 2 fixed bearing block 9 is articulated.
  • a cylinder space 10 in the cylinder body 7 which can be pressurized from the conduit 2 via a hose 11.
  • the piston 6 is loaded from the front by a back pressure spring 12.
  • the cylinder body 7 is mounted in a manner not shown parallel to the longitudinal axis 3 relative to the conduit 2.
  • the leg 18 of the angle lever 14 arrives after an initial, slight backward displacement of the cylinder body 7 relative to the coupling head from the front into contact with the stop surface 20 and prevents the cylinder body 7 from moving further backward relative to the coupling head via the bearing block 13.
  • the piston 6 presses under its pressure medium from the cylinder chamber 10 via the piston rod 8 and the bearing block 9, the conduit 2 and thus the line coupling head 1 to the front and thus firmly against the opposite line coupling head, not shown, whereby the line coupling rings, also not shown, firmly and thus tightly against each other be pressed.
  • the parts of the clutch are in the position shown in FIG. 2, the piston 6 being located in the cylinder body 7 near its front end position.
  • the short-stroke cylinder can be designed as a membrane cylinder.
  • the line coupling head in the coupled state of the line coupling the line coupling head can be elastically pressed back against the pneumatic load by the short stroke cylinder, so that only a part of the short stroke cylinder which is not rigidly coupled to the line coupling head is locked against backward displacement. This prevents damage to the line coupling head.
  • front and the direction of the arrow 4 or the longitudinal axis 3 refer to the line coupling above, ie their directions can deviate considerably from the longitudinal axis of the coupling and the forward direction related to the coupling head:
  • the longitudinal axis 3 With Willison coupling heads, the longitudinal axis 3, relative to the longitudinal axis of this Willison coupling head, is pivoted to the side, for example by approximately 30 °.
  • the automatic coupling for rail vehicles has a protruding, spring-returnable line coupling head 1.
  • a short-stroke cylinder 5 is provided for pneumatic sealing support of the line coupling, the piston 6 of which is articulated on the line coupling head 1 and the cylinder body 7 of which is held relative to the line coupling head 1.
  • the short-stroke cylinder 5 When the short-stroke cylinder 5 is pressurized, the relative displacement of the piston rod 8 and the cylinder body 7 rotates an angle lever 14 which is rotatably mounted on the cylinder body 7 such that one of its legs 18 bears against a stop face 20 of the coupling head from the front and thus locks the cylinder body 7 against backward displacement .
  • the force resulting from the pressure medium acting on the piston 6 is then transmitted as a forward-facing force on the line coupling head 1, whereby the pressing and thus sealing of its coupling sealing ring to the countercurrent coupling head is supported.
