  • the coupling process is carried out fully automatically by both a mechanical coupling of the two coupling heads as well as a coupling of the connecting lines, including the pneumatic connecting lines takes place.
  • the coupling head is provided with a two-part coupling surface.
  • the rear facing the rail vehicle coupling surface extends transversely to the longitudinal center axis of the coupling head, while the front coupling surface is disposed on an exposed and projecting forward hook-like head portion and extends obliquely to the longitudinal center axis of the coupling head.
  • the rear coupling surface is provided with a recess into which engages the front, exposed head portion of the counter-coupling during the coupling process.
  • the respective coupling head is provided with a securing bracket, which serves to lock the head part of the counter-coupling.
  • a valve arrangement is provided, which is provided with a substantially extending inside the coupling head rod, which projects beyond the coupling head end.
  • a spring-loaded poppet valve is arranged on the rod itself, which shuts off the pneumatic connecting line in the unloaded state.
  • On the front of the respective rod is surrounded by a permanently installed sealing ring. During the coupling process, the two sealing rings come to rest against each other and the end of the one rod strikes the end of the other, arranged in the counter-coupling rod. This shifts the respective rod back into the respective coupling head and opens the poppet valve, whereby the pneumatic connecting lines of the two coupling heads are connected together.

  • Under pneumatic supply line can be understood in the present case, both a brake line as well as a conventional pneumatic feed line, wherein a coupling head can of course be provided with both of said supply lines.
  • the two supply lines are preferably arranged one above the other. For the sake of simplicity, however, only one pneumatic supply line will be discussed below. It is understood that in the presence of two pneumatic supply lines preferably both are provided with the elements set forth in detail below, or operate according to the principle explained, with possibly only a 3/2-way valve are provided for driving the corresponding elements got to.

  • the bush 11 is provided with an annular shoulder 12 and the coupling member 10 with an annular collar 13. Between the shoulder 12 of the bushing 11 and the collar 13 of the coupling member 10, a compression spring 14 is clamped, which presses the coupling member 10 in the illustrated here, rest position.
  • the coupling member 10 is frontally provided with a circumferential sealing lip 15.
  • a shut-off valve 17 which serves to shut off the supply line 2 in the uncoupled state of the coupling head 1.
  • the pneumatic supply line is labeled 2.1 and then 2.2.
  • the shut-off valve 17 has a shut-off device 18 loaded by means of a spring 19, which in the idle state shuts off the supply line 2 at a valve seat 22 adapted to the shut-off device 18.
  • On the back of the obturator 18 is provided with a circumferential collar 20.
  • a front part of the obturator 18 surrounding annular channel 27 is provided.
  • a locking member 16 For mechanical securing of mechanical coupling elements (not shown), which in the coupling process at the respective engage other coupling head (counter coupling) and mechanically connect the two coupling heads together, a locking member 16 is provided.
  • the locking member 16 has three positions: a dome-ready position designated A, a locking position B and a disengaged position C. At the end of the mechanical coupling operation, the locking member 16 rotates in the designated B locking position. In this locking position B, the locking member 16 secures the mechanical coupling mechanism against accidental release.
  • a pneumatic 3/2-way valve 23 for the pneumatic control of the coupling member 10 and the shut-off valve 17 is provided.
  • This 3/2-way valve 23 is mechanically coupled to the locking member 16 so that it is in the positions A and C of the locking member 16 in the upper rest position (uncoupling position), while it is in the position B of the locking member 16 in the lower operative position (coupling position) remains.
  • a connecting line 24 leads to the left input side of the 3/2-way valve 23, whereby the latter is pneumatically connected to the upstream of the obturator 18 right part 2.1 of the supply line 2.
  • a first outlet line 25 leads to the back of the collar 13 of the coupling member 10 and a second outlet line 26 to the front of the arranged on the obturator 18 collar 20th

  • the rear side (inner side) of the obturator 18 is subjected to the pressure prevailing in the right-hand part 2.1 of the connecting line and loaded on the surface designated F3 in such a way that the action of the spring 19 in the closed state of the obturator 18 is supported.
  • the obturator 18 is provided with a further, pneumatically acted surface F2, the latter being dimensioned such that when pressurizing the second surface F2 via the outgoing line 26, the force acting on this further surface F2 force is greater at least by the spring bias of the spring 19 , as the force exerted on the first surface F2 by pressurizing the supply line 2, so that the obturator 18 is pneumatically displaceable against the spring force.
  • the pressure on the front equalizes the pressure on the back of the obturator 18, whereby the obturator is suddenly moved into the open position.
  • the pressure-effective surface on the back of the collar 13 of the coupling member 10 is denoted by F1.
  • the pressure-effective surface F1 on the collar 13 of the coupling member 10 and the collar 20 of the obturator 18 is dimensioned in relation to the respective spring force such that first the coupling member 10 from the rest to the operative position and only then the obturator 18 of the shut-off is moved into the open position. This can prevent that the connecting line 2 is opened before it is connected via the coupling member 10 to the connecting line of the counter-coupling.
  • the coupling member 10 is pneumatically at least by the vertical distance H between the shock and sliding surface 7 and the coupling surface 3 on the clutch surface 3 also displaced. This can ensure that even then a pneumatic connection between the coupling member 10 of the future connection line 2 and the coupling member of the connecting line of the counter-coupling comes about, if only this world-side coupling member 10 is moved from the rest to the operative position. This is the case, for example, if only one, this side, clutch assembly is supplied with compressed air, as will be explained in more detail below.
  • the this side coupling head 1 as well as the counter-coupling 1a, of which only the area is shown around the coupling member 10a, in the initial state, ie in the ready-coupling position.
  • the locking member 16 stands in the dome-ready position A and the associated 3/2-way valve 23 in the upper rest position, in which the two outgoing lines 25, 26 are open to the atmosphere, while the connecting line 24 is locked within the valve 23 is.
  • the coupling member 10 is in the engaged state of rest, so that it is not damaged by the counter-movement 1a performing a relative movement.
  • the obturator 18 occupies the supply line 2 shut off hibernation.
  • Fig. 3 shows the state after the two coupling heads were mechanically coupled together.
  • the locking member 16 is in the locking position B and the valve 23 has been switched from the upper rest to the lower operative position, in which the two outgoing lines 25, 26 are acted upon by the valve 23 with compressed air.
  • the collar of the coupling member 10 is pressurized with compressed air, whereby the coupling member 10 is pneumatically moved forward in the illustrated operative position.
  • the coupling member 10a there is a connection between the supply lines 2, 2a via the two coupling members 10, 10a.
  • the obturator 18 is also displaced pneumatically from the shut-off to the open position against the spring force, whereby the supply line 2 is opened and the two coupling heads 1, 1 a are pneumatically interconnected (FIG. 4).
  • the front side of the respective coupling member 10 arranged sealing lip 15 ensures a tight connection.
  • the locking member 16 is first rotated from the locking position B to the uncoupled position C. This can be done manually or automatically, depending on the design of the coupling.
  • the mechanical coupling elements are unlocked and the valve 23 is switched from the upper coupling to the lower uncoupling position, whereby the pressure in the outlet lines 25, 26 can escape into the atmosphere.
  • the obturator 18 moves from the open to the shut-off position and closes the supply line (FIG. 5).
  • the coupling member 10 is moved to the engaged rest position (Fig. 6) and interrupts the connection between the supply lines.
  • the counter-coupling 1a is mechanically removed and the locking member 16 is rotated in the coupling-ready position A (Fig. 7).
  • FIGS 8 to 10 show different phases during the coupling process, in contrast to the above-described coupling process only the right, this side, the two to be coupled coupling heads 1, 1a is supplied with compressed air.
  • the end face of the obturator of the counter-coupling 1a is also supplied with compressed air, so that this lifts off from the valve seat. Since the 3/2-way valve in the counter-coupling 1a has already been moved from the rest to the operative position during the mechanical coupling process, the obturator is now moved from the shut-off to the open position. Thereafter, the collar of the coupling member 10a and the obturator (not shown) is pneumatically pressurized and the two coupling members 10, 10a oscillate with time in a middle position between the two coupling heads 1, 1a a.
  • Fig. 13 shows a coupling head with an alternative embodiment of a coupling member 29, wherein the connecting element is in turn provided with the reference numeral 9.

  • the coupling member 29 is displaceable against the spring force transversely to the coupling surface 3.
  • the fundamental difference compared to the previously described with reference to Figures 1 to 12 coupling member 10 is that the coupling member 29 shown here on the one hand has a disengaged rest position and on the other hand is not pneumatically moved from the rest to the operative position. Rather, the coupling member 29 on a disengaged rest position.
  • the coupling member 29 is moved relative to the coupling surface 3 during the coupling process on the chamfered lateral surface 8 by the counter-coupling 1b.
  • the coupling member is also provided in this case with a central through-opening 32 and a through-opening 32 comprehensive, frontally disposed seal 33. Possibly. can also be dispensed with in this variant, arranged on the pneumatic line shut-off valve 17.
