Definitions

  • the present invention relates to an automatic train coupling, in particular for a freight car of a rail vehicle, according to the preamble of claim 1.
  • automatic pulling couplings of the generic type which have a coupling head with a coupling housing and a coupling lock with a lock.
  • the coupling lock is designed as a twist lock with a coupling eye and a frog, the frog being rotatable about a main axis between a ready-to-couple position, a coupled position and a decoupled position, and the coupling eye is connected to the frog with a first end rotatable about a coupling eye axis and has a second free end.
  • the frog has a mouth for receiving a corresponding second end of a coupling eye of an opposing coupling head.
  • a spring accumulator is assigned to the centerpiece.
  • the centerpiece can be rotated against the force of the spring accumulator from the coupled position into the decoupled position and by the force of the spring accumulator from the decoupled position into the coupling-ready position and from the coupling-ready position into the coupled position.
  • the lock which holds the coupling lock in the appropriate position or releases it to transition to another position by turning the frog, has a plunger that can be displaced against a spring force in the coupling direction of the pulling coupling and a ratchet rod that can be moved transversely or obliquely to the coupling direction.
  • the pawl rod is connected to the frog in an articulated manner and can be displaced from the frog when it is rotated from the coupled position into the uncoupled position into a latching position in which the pawl rod rotates the frog back, that is, blocked in the direction from the uncoupled position to the coupled position.
  • the punch in turn is movable between a first position and a second position.
  • the plunger In the first position, in which the plunger is displaced against the spring force, the plunger blocks the ratchet rod in the latching position and in the second position, in which the plunger is displaced from the first position by the spring force, the plunger releases the pawl rod Detent position.
  • the function of the generic automatic towing coupling is as follows: Two coupling heads of the same type on two vehicles to be coupled are locked together by inserting the second end of the respective coupling eye into the mouth of the frog of the other coupling head and holding it in a form-fitting manner by twisting the frog there becomes. The two vehicles are then mechanically coupled to one another.
  • the two dome locks are only loaded by tensile forces that are evenly distributed over both dome eyes within the parallelogram formed by the dome loops and the frogs. Compressive forces, on the other hand, are transmitted by a special profile on the front of the coupling head housing, the profile usually, as is also advantageous in the present invention, comprising a cone and a funnel, which are enclosed by a wide, in particular flat end face.
  • the profile can be formed by a separate face plate that is attached to the front of the coupling head housing.
  • the profile can form sliding and centering surfaces with the cone and funnel and, in particular, determine the gripping area in terms of lateral, vertical and angular offset. When the coupling heads meet, they center and slide into each other.
  • a decoupling device rotates both coupling locks, i.e. the two frogs against the force of the spring accumulator, until the coupling eyes slide out of the mouths of the frogs.
  • the twisting frogs should move the ratchet rods so far that when the vehicles are separated, turning the frogs back from the uncoupled position beyond the position ready for coupling is prevented by bringing the ratchet rods into their locking positions.
  • the pull couplings are designed in such a way that the coupling heads or coupling locks operate alternately. If, for example, a coupling lock is released with a manual uncoupling or also with an automated uncoupling, in that its core is rotated against the force of the spring accumulator, this rotary movement is via the Transfer the coupling eyes articulated to the frog and the mouth of the opposite frog to the opposite frog. Correspondingly, the opposing frog transmits its rotary movement to its ratchet rod in such a way that it reaches its latching position.
  • the present invention is therefore based on the object of improving a generic automatic pulling coupling in such a way that locking of the frog is reliably achieved by moving the ratchet rod into the latching position even with a coupling head that is passively actuated, as shown.
  • An automatic train coupling according to the invention in particular for a freight car of a rail vehicle, has a coupling head which comprises a coupling head housing and a coupling lock with a locking device.
  • the coupling lock is designed as a twist lock with a coupling eyelet and a frog, the frog being rotatable about a main axis between a position ready for coupling, a coupled position and a decoupled position.
  • the decoupled position can coincide with the position ready for coupling, or, viewed from the coupled position, the decoupled position is provided beyond the position ready for coupling, based on the rotary movement of the frog.
  • the coupling eye is connected to the frog with a first end so that it can be rotated about a coupling eye axis and has a second free end.
  • the second free end forms in particular a crossbar in order to achieve the loop-shaped shape of the coupling loop.
  • the frog has a mouth which is arranged to receive a second end of a coupling lug of an opposite coupling head, and the frog is against the force of a spring accumulator from the coupled position into the decoupled position and by the force of the spring accumulator at least from the decoupled position in the coupled position can be rotated, especially if the uncoupled position does not coincide with the ready-to-couple position, rotatable by the force of the spring accumulator from the uncoupled position to the ready-to-couple position and from the ready-to-couple position to the coupled position.
  • the cross bar of the coupling eye is inserted into the mouth.
  • the locking of the coupling lock has a plunger which can be displaced against a spring force in the coupling direction of the pulling coupling and a ratchet rod which can be displaced transversely or obliquely to the coupling direction.
  • the pawl rod is connected to the frog in an articulated manner and when it is rotated from the coupled position into the uncoupled position can be displaced into a latching position in which the pawl rod blocks rotation of the frog from the uncoupled position into the coupled position.
  • the plunger In a first position displaced against the spring force, the plunger blocks the ratchet rod in the latching position and releases the ratchet rod from the latching position when it is in a second position displaced by the spring force.
  • the latching position of the ratchet rod is now positioned, that is to say selected in such a way, that the ratchet rod is already shifted into the latching position before the frog reaches its uncoupled position.
  • the ratchet rod reaches the latching position earlier, even if the frog has not yet been rotated as far as possible from the coupled position in the direction of the uncoupled position.
  • the ratchet bar thus reaches the latching position already in a predetermined twisted position of the frog in the direction of rotation from the coupled to the uncoupled position, the predefined twisted position having a twist angle difference compared to the twisted position of the frog in the mentioned maximum possible twisted position.
  • the ratchet rod reaches the latching position earlier, which can be achieved, for example, in that a latching projection of the ratchet rod comes into engagement earlier with a latching projection of a guide for the ratchet rod if the frog is not yet completely out the coupled position up to its maximum possible twisted position, in which it assumes the uncoupled position, was rotated.
  • a conventional ratchet rod can be modified, for example, in that its latching projection is positioned comparatively further away from a connection of the latch rod on the frog and / or the latching projection of the guide is positioned comparatively closer to the connection of the latch rod on the frog.
  • the solution according to the invention ensures that, at least as soon as the punch has been moved from the second position to the first position, the ratchet rod engages in a counter bearing, even if the frog connected to the ratchet rod was not previously rotated maximally in the direction of the uncoupled position.
  • This is particularly important for the passively operated coupling lock described at the beginning, in which the frog is not rotated directly by an automated decoupling connected to it or by a manual decoupling, but indirectly via the opposite frog and the dome loops connected to it or via the opposite frog and its own coupling eye, which is shifted accordingly from the opposite frog.
  • a shifting position of the pawl rod is defined in which the pawl rod has been shifted far enough in the direction of the punch to be released by the punch in its second position on a counter bearing, for example on a guide of the punch, to click into place.
  • the ratchet rod can assume the latching position, which can accordingly also be called the ready-to-latch position, before the punch releases the actual latching with the counter bearing.
  • the punch has an opening which at least partially or completely encloses the ratchet rod and which
  • the ratchet bar forms with the counter bearing, in particular on a guide of the ram, a locking connection with two interengaging locking projections, which can also be called locking lugs, wherein the ratchet bar can be actuated by moving the ram from the first to the second position to end mutual engagement of the locking projections.
  • the pawl rod has a latching projection which is positioned to be displaced over the latching projection of the counter bearing when the frog to which the pawl rod is connected is rotated from the coupled position to the uncoupled position, wherein in the uncoupled position , that is, with a maximum rotation of the frog out of the coupled position in the direction of the uncoupled position, a distance between the locking projections in the direction of displacement of the ratchet rod is set.
  • the latching position of the ratchet rod is advantageously positioned in such a way that the latch rod is already shifted into the latching position or ready-to-latch position before the frog reaches its uncoupled position or any uncoupling position at all, so that the latch rod is in the uncoupled position of the Heart piece has been moved beyond the locking position, so to speak.
  • an elastic spring element is provided, against the spring force of which the ratchet rod can be brought into the latching position.
  • the spring element is positioned to press the latching projections into one another transversely to the direction of displacement of the ratchet rod for mutual engagement.
  • the punch can preferably be brought into engagement with the ratchet rod in the region of the opening in such a way that it moves from the first into the second
  • the coupling head preferably has a manual uncoupling.
  • the manual decoupling can be accessible for its actuation from only one side transversely to the coupling direction.
  • a structurally complex manual uncoupling arranged on both sides can be omitted and the operating times can be shortened because according to the invention it is ensured that the passively operated coupling lock is always safely brought into the desired position ready for coupling.
  • impulse lines were provided for transmitting a decoupling impulse, through which the aforementioned play in the pulling coupling or in the coupling joint was canceled, then these impulse lines for transmitting the decoupling impulse and for feeding the uncoupling cylinder of the counter coupling can be used in the solution according to the invention omitted.
  • the operating instructions for uncoupling can also be simplified. Braking and pushing the vehicles of long trains before separating the vehicles can be dispensed with.
  • the inventive solution in particular ensures an improved geometric arrangement of the locking lug on the ratchet rod, which ensures that the passively actuated coupling lock locks both coupling heads in the ready-to-couple position in the event of a superimposed movement consisting of opening the coupling locks and moving the coupling heads apart.
  • Air coupling valves which are controlled by the closing movement around the main axis, are thus also reliably closed, if provided. This prevents the main air line from venting and the corresponding rail vehicle from being braked to the maximum in the Maneuvering area is. The release of the brakes has so far led to an unfavorable delay, especially in the case of longer car units, due to the need to fill the air reservoirs.
  • the manual decoupling comprises, for example, a cable pull or another gear with at least one chain, a linkage or a lever system.
  • the decoupling movement is transmitted via a cable pull to a decoupling lever, which causes the corresponding frog to rotate.
  • the frog is in particular mounted on a main bolt and is advantageously connected to the main bolt in a rotationally fixed manner, so that the frog is also rotated by rotating the main bolt.
  • the main bolt accordingly extends along the main axis and is rotatable about the main axis.
  • the manual decoupling can also act on the main bolt to rotate it.
  • Manual uncouplers are used in particular when there is no energy available for automated uncoupling, for example in the case of train couplings on freight wagons.
  • the uncoupling and thus the opening of the coupling lock can then take place directly on the coupling head at the end of the car.
  • a rail vehicle according to the invention has an automatic train coupling of the type shown.
  • a rail vehicle comprises several cars - motor coaches and / or passenger cars / freight cars - which are each coupled by means of an automatic train coupling according to the invention, each automatic train coupling having two corresponding coupling heads, of which the heart of one (passively actuated) coupling lock is indirectly via the rotation of the heart of the other (actively operated) coupling lock is effected by this rotation being transmitted via the coupling eyelet.

  • the coupling eye 5 has a first end 5.1, at which it is rotatably connected to the frog 6, as well as an opposite second end 5.2, which can be clamped in a mouth 9 of the frog 6 of an opposing coupling head 1, around the two coupling heads 1 mechanically to lock together, such as in the Figures 2 and 4th is shown.
