Definitions

  • the invention relates to a coupling head for a track-guided vehicle, in particular rail vehicle, according to the preamble of the independent claim 1.
  • the invention relates to a coupling head for a track-guided vehicle for forming a mechanical connection with a matching mating coupling head, wherein the coupling head has a locking element which serves to prevent inadvertent release of the mechanical connection between the coupling head and a coupling head coupled to the coupling head.
  • the locking element is movable from a first position, in which a release of the mechanical connection between the coupling head and the counter-coupling head is prevented, to a second position, in which a release of the mechanical connection between the coupling head and the counter-coupling head is made possible.
  • the generic coupling head on a first and a second actuating element which are each movable vertically to the coupling direction relative to the coupling head and connected to the locking element such that upon movement of the actuating elements relative to the coupling head, the locking element from its first to its second position and conversely is convertible.
  • a lever element which has a first region to which an end portion of the first actuating element is articulated such that upon pivoting of the lever member, the first actuating element vertically to Coupling direction is moved relative to the coupling head, wherein the lever element further comprises a second region for cooperation with an end portion of a second actuating element coupled to the coupling head, identical counter-coupling head such that upon pivoting of the lever member, the second actuating element of the counter-coupling head vertical to the coupling direction relative to the Counter-coupling head is movable.
  • Such a coupling head is already known, at least in principle, from the prior art.
  • a coupling head of a central buffer coupling of the type Georg Fischer is called.
  • a mechanism for releasing the mechanical connection between two mutually coupled coupling heads is used in so-called Georg Fischer couplings (GF coupling), which is structurally and functionally comparable to the mechanism described above consisting of locking element, first actuating element, second actuator and lever member.
  • GF coupling is structurally and functionally comparable to the mechanism described above consisting of locking element, first actuating element, second actuator and lever member.
  • uncoupling can be effected either automatically or manually.
  • Coupling heads of GF couplings each have a locking element to prevent inadvertent release of the mechanical connection between two coupled coupling heads. Accordingly, the mechanical connection between two coupled coupling heads of a GF coupling is secured by two locking elements. To release this connection consequently both locking elements must be opened.
  • Mechanisms for releasing two coupling heads are known from the prior art, wherein usually a common lever element is used, which is in operative connection with the locking elements of both coupling heads, so that they are released simultaneously upon actuation of the lever member.
  • a common lever element with which an actuating element of the coupling on the one hand and an actuating element of the counter-coupling on the other hand cooperate, represents an easy-to-implement and effective solution with which the uncoupling is executable.
  • Fig. 1 a known from the prior art coupling head 100 of the type Georg Fischer shown in a coupled with an identical mating coupling head 100 'state.
  • the coupling head 100 has a lever element 104 for releasing the mechanical connection between the coupling head 100 and the mating coupling head 100 '.
  • the lever element 104 has a first region 104 a, where it is connected to the upper end region of a first actuating element 102.
  • the connection point between the lever element 104 and the first actuating element 102 determines in this case the vertical axis of rotation about which the lever element 104 is pivotable.
  • the lever element 104 rests on the upper end region of a second actuating element 103 '.
  • the two actuating elements 102, 103 ' are each connected to a locking element 101, 101'.
  • the locking elements 101, 101 ' serve to non-positively connect the coupling heads 100, 100' with each other.
  • the lever element 104 is deflected in the direction of the arrow, as a result of which the first actuating element 102, which is connected to the lever element 104 on the first region 104a, is pulled vertically out of the coupling head 100. Since the first actuating element 102 is directly connected to the locking element 101, a force transmission takes place, which transfers the locking element 101 from a first, closed position to a second, opened position.
  • the second actuating element 103 'of the counter-coupling head 100' is pressed into the counter-coupling head 100 'by the reaction force on the second region 104b of the lever element 104.
  • the second actuating element 103 ' is also connected to a locking element 101' and is also used to transfer the locking element 101 'from a first closed position to a second opened position.
  • FIG. 1 illustrated second actuator 103 'is accordingly connected to the locking element 101' of the mating coupling head 100 '.
  • the invention has the object, a coupling head of the type mentioned in such a way that even under high tensile forces a smooth release of the coupling connection is made possible.
  • the solution according to the invention is characterized in that in a coupling head of the type mentioned further, a bearing is provided for supporting the lever member between the first and the second region such that the lever member is pivotable about a predetermined vertical axis.
  • a horizontal axis of rotation is defined for the lever element between its first and its second region, wherein two degrees of translational freedom of the lever element are fixed or at least be predetermined in advance, so that the lever element can only be given away around the axis of rotation.
  • the bearing has a vertically aligned shaft which defines the vertical pivot axis of the lever element. It is conceivable that the shaft is releasably secured to the coupling head. This makes it possible that, for example, a conventional coupling head, wherein in the coupled state with a counter-coupling head synchronous operation of the locking elements is not guaranteed, can be retrofitted in a simple manner.
  • the shaft it is conceivable to releasably secure the shaft to a housing frame on the coupling head, wherein the housing frame has a gap in which the lever element is mounted rotatably parallel to the coupling plane around the shaft.
  • the geometry of the housing frame can be chosen in a particularly advantageous manner so that the range of the rotational movement of the lever member is limited to the required angle for coupling and decoupling angle range.
  • the bearing provided for supporting the lever element bearing has a shaft which is received in a groove extending in the coupling direction such that the shaft is guided during pivoting of the lever member in the coupling direction to compensate for a change in length of the lever arm between the Shaft and the first portion of the lever member to which the end portion of the first actuating element is articulated.
  • the first actuator Upon deflection of the lever member is on the first actuator transmit a force to the locking element. Since the first actuating element can be moved in a preferred manner only vertical to the coupling direction relative to the coupling head, it is therefore preferred to form the lever element which is connected to the actuating element so that the circular movement of the lever element can be converted into a vertical movement. This can be realized in a simple and cost-effective manner by the guidance of the shaft in a groove extending in the coupling direction.
  • the lever element is provided with a slot in which the first actuating element is releasably secured. Through the slot, the first actuator can be safely and yet rotatably mounted on the lever element. Preferably, the first actuating element is screwed to the lever element. As a result, a robust connection of the two parts is achieved, which is easily solvable for possible repairs.
  • a guide is provided on the end region of the second actuating element for guiding the second region of a lever element belonging to the mating coupling head during pivoting of the lever element belonging to the mating coupling head relative to the end region of the second actuating element.
  • the guide has a guide groove extending in the coupling direction.
  • Fig. 1 a known from the prior art coupling head 100 of the type Georg Fischer shown in a coupled with an identical mating coupling head 100 'state.
  • the coupling heads 100, 100 'are under tensile load during the decoupling process Therefore, there is the danger in the solution known from the prior art that one of the actuating elements 102, 103 'jams and the associated locking element 101, 101' can not thereby be opened.
  • the other, not jammed actuator 102, 103 ' is still moving and the corresponding locking element 101, 101' unlocked. Then, the entire tensile load on the locking element 101, 101 'of the other coupling head 100, 100' is transmitted. This has the consequence that the coupling heads 100, 100 'are not readily decoupled.
  • Fig. 2 shows a plan view of a half of an exemplary embodiment of a coupling head 20 of the present invention in the coupled state.
  • the coupling head 20 serves to form a mechanical connection with an identical counter-coupling head 20 '.
  • the coupling head 20 on a locking element 1, which serves to prevent unintentional release of the mechanical connection between the coupling head 20 and coupled to the coupling head 20 counter-coupling head 20 '.
  • the locking element 1 from a first position in which a release of the mechanical connection between the coupling head 20 and the mating coupling head 20 'is prevented, in a second position in which a release of the mechanical connection between the coupling head 20th and the mating head 20 'is movable.
  • a lever member 4 is provided, which has a first portion 4a, to which an end portion of the first actuating element 2 is articulated such that upon pivoting of the lever member 4, the first actuating element 2 is moved vertically to the coupling direction L relative to the coupling head 20.
  • the lever element 4 also has a second region 4b, which cooperates with an end region of a second actuating element 3 'of an identical counter-coupling head 20' coupled to the coupling head 20 such that upon pivoting of the lever element 4, the second actuating element 3 'of the counter-coupling head 20' is vertical to the coupling direction L relative to the counter-coupling head 20 'is movable.
  • the coupling head 20 is characterized in that a bearing 5 is also provided for supporting the lever element 4 between the first and the second region 4a, 4b such that the lever element 4 is pivotable about a predeterminable vertical axis.
  • the bearing 5 has a vertically aligned shaft 6, as a result, the vertical pivot axis of the lever member 4 is fixed, the shaft 6 is preferably releasably attached to the coupling head 20.
  • the shaft 6 is received in a extending in the coupling direction L groove 7 such that the shaft 6 is guided during pivoting of the lever member 4 in the coupling direction L to compensate for a change in length of the lever arm between the shaft 6 and the first portion 4a of the lever member 4, on which the end portion of the first actuating element 2 is articulated.
  • the lever member 4 can only move as long as both actuators 2, 3 'are movable.
  • the second actuator 3 'of the mating coupling head 20' not be movable, the pivoting of the lever member 1 and thus the extraction of the first actuating element 2 is prevented in the coupling head 20 according to the invention, since the shaft 6 is not substantially movable in the horizontal direction.
  • the first actuating element 2 is also activated again. Because of this it is guaranteed that both locking elements 1, 1 'can be opened synchronously at any time.
  • Fig. 3 shows a plan view of a half of the exemplary embodiment of the coupling head according to Fig. 2 when uncoupling.
  • the first actuating element 2 is pulled out of the coupling head 20, while the second actuating element 3 'is pressed into the counter-coupling head 20'.
  • the shaft 6 Since the actuating elements 2, 3 'are movable exclusively vertically to the coupling axis L, the shaft 6 must be displaceable in the coupling direction L in order to compensate for a shortening of the lever arm between the shaft 6 and the first region 4 a of the lever element 4 when the lever element 4 is pivoted can.
  • the front region of the lever element 4 preferably moves in a groove 9 located at the upper end region of the second actuating element 3. By the latter, it is possible for the second region of the lever element 4 to be in optimum operative contact with the upper end region of the second actuating element 3, the counter-coupling , comes in.
  • Fig. 4 shows a perspective, schematic view of a coupling head according to the invention during decoupling
