Description

Die Erfindung betrifft eine Übergangskupplung für Schienenfahrzeuge zum Kuppeln einer selbsttätigen Kupplung des Willison-Typs mit einer handbetätigbaren Hakenkupplung, wobei die selbsttätige Kupplung im Bereich eines seitlich von starren Kupplungsklauen eingefaßten Kupplungsmauls einen Riegel und einen Taster und die Hakenkupplung als Kupplungsteile einen Kupplungshaken und ein Ösenteil aufweist, wobei ein diesen Kupplungsteilen entsprechendes Kupplungsteil in einer Ausnehmung des Kupplungskopfes der selbsttätigen Kupplung etwa seitlich des Riegels gehaltert ist und nach vorn durch das Kupplungsmaul zu ragen vermag oder von vorne durch das Kupplungsmaul zugänglich ist.The invention relates to a transition coupling for rail vehicles for coupling an automatic coupling of the Willison type with a manually operable hook coupling, the automatic coupling having a latch and a button in the region of a coupling mouth bordered laterally by rigid coupling claws and the hook coupling as coupling parts having a coupling hook and an eyelet part , wherein a coupling part corresponding to these coupling parts is held in a recess of the coupling head of the automatic coupling approximately to the side of the bolt and can protrude forward through the coupling mouth or is accessible from the front through the coupling mouth.

Derartige Übergangskupplunen sind beispielsweise aus der DE-C-398 976, der DE-A-1 934 008 und der DF-A-2 153 620 bekannt. Bei diesen bekannten Anordnungen ist jeweils das in Art einer Kuppelkette mit Spannschloß ausgebildete Ösenteil um einen waagerechten Querbolzen drehbar in der Ausnehmung des Kupplungskopfes gelagert, wobei es im unbenutzten Zustand vertikal nach unten aus dem Kupplungskopf heraushängt und nur im Betriebszustand in eine horizontale Lage geschwenkt wird. Bei modernen Ausführungen von Kupplungen des Willison-Typs sind jedoch oftmals unterhalbs des eigentlichen Kupplungskopfes Vorrichtungen zum selbsttätigen Kuppeln pneumatischer und/ oder elektrischer Leitungen vorgesehen, welche sich in jenem Raum befinden, welchen das im unbenutzten Zustand herabhängende Ösenteil ebenfalls für sich beansprucht. Es ist somit nicht möglich, an einer selbsttätigen Kupplung der genannten Art sowohl die zumeist erforderlichen Leitungskupplungen als auch eine Übergangskupplung der erwähnten, bekannten Art anzuordnen.Such transition couplings are known for example from DE-C-398 976, DE-A-1 934 008 and DF-A-2 153 620. In these known arrangements, the eye part designed in the manner of a dome chain with a turnbuckle is rotatably mounted in the recess of the coupling head about a horizontal transverse bolt, and in the unused state it hangs vertically downward from the coupling head and is pivoted into a horizontal position only in the operating state. In modern designs of couplings of the Willison type, however, devices for automatic coupling of pneumatic and / or electrical lines are often provided below the actual coupling head, which are located in the space which the eyelet part, which is hanging when not in use, also claims for itself. It is therefore not possible to arrange both the usually required line couplings and a transition coupling of the known type mentioned on an automatic coupling of the type mentioned.

Weiterhin ist es beispielsweise gemäß der DE-C-1 211 679 bekannt, seitlich am Kupplungskopf ein hakenhartiges Teil anzuformen, in welches zum gemischten Kuppeln die Kuppelkette einer üblichen Hakenkupplung einhängbar ist. Hierbei ergibt sich jedoch der Mangel, daß beim gemischten Kuppeln der Kupplungskopf der selbsttätigen Kupplung zur Seite ausgeschwenkt werden muß, so daß sich kein geradliniger Zugkraftübergang zwischen den gekuppelten Fahrzeugen ergibt.Furthermore, according to DE-C-1 211 679, for example, it is known to form a hook-hard part on the side of the coupling head, in which the coupling chain of a conventional hook coupling can be suspended for mixed coupling. Here, however, there is the defect that, in the case of mixed coupling, the coupling head of the automatic coupling must be swung out to the side, so that there is no straightforward transfer of tractive force between the coupled vehicles.

Aus der DE-C- 1 050 361 ist es schließlich für eine andersartige, selbsttätige Kupplung bekannt in einem zentralen, kupplungsmaulähnlichen Bereich ein Ösenglied einer Übergangskupplung mittels einer in Kupplungslängsrichtung verlaufenden Gewindespindel zu haltern, wobei mit der Gewindespindel eine axial unverschiebbar gehaltene, willkürlich drehbare Mutter verschraubt ist. Es ist somit die Länge des Ösengliedes willkürlich verkürzbar, so daß im gekuppelten Zustand die Übergangskupplung gestrafft und zwischen den Seitenpuffer der gekuppelten Fahrzeuge vorhandenes Spiel beseitigt werden kann. Jedoch hängt auch bei dieser Übergangskupplung im unbenutzten Zustand das Ösenglied vertikal nach unten aus dem Kupplungskopf heraus.From DE-C-1 050 361 it is finally known for a different type of automatic coupling to hold an eyelet member of a transition coupling in a central, coupling-mouth-like area by means of a threaded spindle running in the longitudinal direction of the coupling, with the threaded spindle being an axially immovable, freely rotatable nut is screwed. It is therefore arbitrarily shortened the length of the eyelet member, so that in the coupled state the transition coupling can be tightened and existing play between the side buffers of the coupled vehicles can be eliminated. However, even with this transition coupling in the unused state, the eye member hangs vertically downward from the coupling head.

Es ist Aufgabe der Erfindung, eine Übergangskupplung der eingangs genannten Art zu schaffen, welche bei einfachem, robustem Aufbau keine im unbenutzten Zustand nach unten aus dem Kupplungskopf heraushängende und damit mit eventuell vorhandenen Leitungskupplungen in Kollision geratende Teile aufweist.It is an object of the invention to provide a transition coupling of the type mentioned at the outset which, with a simple, robust construction, has no parts which hang down from the coupling head when not in use and thus collide with any line couplings which may be present.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß der Kupplungsriegel und die diesem benachbarte Kupplungsklaue etwa im mittleren Bereich ihrer Höhenerstreckung eine Ausnehmung für den Durchtritt bzw. die Zugänglichkeit des höchstens begrenzt horizontal verschieblich gelagerten und im ungekuppelten Zustand vollständig hinter dem Kupplungsmaul befindlichen Kupplungsteils aufweisen.This object is achieved according to the invention in that the coupling bolt and the coupling claw adjacent to it have a recess for the passage or accessibility of the coupling part, which is horizontally displaceable at most to a limited extent and is completely behind the coupling mouth in the uncoupled state, approximately in the central region of its vertical extent.

Die nach der weiteren Erfindung vorteilhaften Ausgestaltungsmöglichkeiten einer derartigen Übergangskupplung sind in den Unteransprüchen aufgezeigt.The advantageous design options of such a transition coupling according to the further invention are shown in the subclaims.

Gemäß Fig. 1 und 2 weist die selbsttätige Kupplung des Willison-Typs einen Kupplungskopf 1 auf, der stirnseitig mit einem Kupplungsmaul 2 versehen ist, zu dessen einer Seite sich eine starre, hakenartige Kupplungsklaue 3 und zu dessen anderer Seite sich eine prismatische, starre Kupplungsklaue 4 befinden. Zur Ausgestaltung zu einer Starrkupplung kann der Kupplungskopf 1 in seinem unteren Bereich einerseits ein übliches Kupplungshorn 5 und andererseits eine mit diesem zusammenwirkende Schürze 6 aufweisen; zwischen dem Kupplungshorn 5 und der Schürze 6 können nicht dargestellte, selbsttätige Leitungskupplungen üblicher Bauart zum selbsttätigen Kuppeln von Luft- und/oder elektrischen Leitungen vorgesehen sein. In den Bereich des Kupplungsmaules 2 ragen ein seitlich neben der Kupplungsklaue 4 angeordneter Riegel 7 und ein neben diesem befindlicher Taster 8, die beide einem üblichen, nicht weiter dargestellten Riegelgetriebe zugehören. Insoweit entspricht die Kupplung einer üblichen Willison-Kupplung.1 and 2, the automatic clutch of the Willison type has a coupling head 1 which is provided on the end face with a coupling jaw 2, on one side of which there is a rigid, hook-like coupling claw 3 and on the other side of which there is a prismatic, rigid coupling claw 4 are located. To design a rigid coupling, the coupling head 1 can have a conventional coupling horn 5 in its lower region on the one hand and an apron 6 interacting with it on the other hand; between the coupling horn 5 and the skirt 6, not shown, automatic line couplings of a conventional type for automatically coupling air and / or electrical lines can be provided. In the area of the coupling mouth 2 protrude a bar 7 arranged laterally next to the coupling claw 4 and a button 8 located next to it, both of which belong to a conventional locking gear, not shown. In this respect, the clutch corresponds to a conventional Willison clutch.

Etwa in halber Höhenerstreckung des Kupplungsmaules 2 und damit auch der Kupplungsklaue 4 sowie des Riegels 7 ist der Kupplungskopf 1 mit einer Ausnehmung 9 versehen, welche nach vorne in den Bereich des Kupplungsmaules 2 geöffnet ist. Der Riegel 7 weist in seinem vorderen Abschnitt eine Ausnehmung 10 auf, welche mit der Ausnehmung 9 korrespondiert und sich somit ebenfalls in der mittleren Höhenerstrekkung des Riegels 7 befindet. Die Kupplungsklaue 4 weist ebenfalls im Bereich ihrer mittleren Höhenerstreckung eine mit der Ausnehmung 9 korrespondierende Ausnehmung 11 auf. In den somit weit nach vorne geöffneten Ausnehmungen 9, 10 und 11 befindet sich gemäß Fig. 3 ein als Kupplungsteil einer Handkupplung dienendes Ösenteil 12. Die Öse 13 des Ösenteiles 12 befindet sich an dessen Vorderende und in der dargestellten Ruhelage dicht hinter dem Kupplungsmaul 2 innerhalb der Ausnehmungen 9, 10 und 11. An die Öse 13 schließt sich ein sich nach rückwärts etwa in Längsrichtung des Kupplungskopfes 1 erstrekkender, kräftiger Schaftteil 14 an, der so bemessen ist, daß er die Kupplungszugkräfte zu übertragen vermag. Der Schaftteil 14 geht an einem Ringflansch 15 in einen wesentlich schwächeren Schaftteil 16 über, welcher in Verlängerung des Schaftteiles 14 nach rückwärts verläuft und mit einem Federteller 17 endet. In der dargestellten Ruhelage befindet sich der Federteller 17 nahe des rückwärtigen Endes der Ausnehmung 9. Der Ringflansch 15 ist mit einer dem Kupplungsmaul 2 zugewandten Anschlagfläche 18 versehen. Dicht hinter der Öse 13 ist die Ausnehmung 9 mit einem Innenflanschring 19 versehen, welcher mit Spiel vom Schaftteil 14 durchgriffen wird, an welchem sich eine andererseits am Federteller 17 anliegende Feder 20 abstützt und welcher rückseitig eine Anschlagfläche 21 aufweist, welche zusammen mit der Anschlagfläche 18 einen Anschlag 18, 21 bildet. Die Feder 20 ist vorgespannt, so daß sie das Ösenteil 12 in die dargestellte Ruhelage zu ziehen und in dieser zu halten vermag; andererseits ist die Feder 20 jedoch derart schwach ausgebildet, daß sie von Hand überwunden werden kann.Approximately halfway up the height of the coupling jaw 2 and thus also the coupling claw 4 and the bolt 7, the coupling head 1 is provided with a recess 9 which is open towards the front in the region of the coupling jaw 2. The bolt 7 has in its front section a recess 10, which corresponds to the recess 9 and itself thus also located in the middle vertical extent of the bolt 7. The coupling claw 4 likewise has a recess 11 corresponding to the recess 9 in the region of its central height extent. 3 there is an eyelet part 12 serving as a coupling part of a hand coupling. The eyelet 13 of the eyelet part 12 is located at its front end and in the rest position shown, just behind the coupling mouth 2 inside of the recesses 9, 10 and 11. The eyelet 13 is followed by a strong shaft part 14 which extends backwards approximately in the longitudinal direction of the coupling head 1 and is dimensioned such that it is able to transmit the coupling tensile forces. The shaft part 14 merges on an annular flange 15 into a much weaker shaft part 16, which extends backwards in the extension of the shaft part 14 and ends with a spring plate 17. In the rest position shown, the spring plate 17 is located near the rear end of the recess 9. The ring flange 15 is provided with a stop surface 18 facing the coupling mouth 2. Close behind the eyelet 13, the recess 9 is provided with an inner flange ring 19, which is penetrated with play by the shaft part 14, on which a spring 20, which on the other hand rests on the spring plate 17, is supported and which has a stop surface 21 on the back, which together with the stop surface 18 forms a stop 18, 21. The spring 20 is biased so that it can pull the eyelet 12 into the rest position shown and hold it in this position; on the other hand, the spring 20 is so weak that it can be overcome by hand.

Im Ruhezustand der Übergangskupplung nimmt das Ösenteil 12 die aus Fig. 3 ersichtliche Lage ein, in welcher es durch die Feder 20 völlig in die Ausnehmung 9 zurückgezogen ist und sich seine Öse 13 dicht hinter dem Kupplungsmaul 2 befindet. Zum gemmischten Kuppeln ist das Ösenteil 12 aus dem Kupplungskopf 1 teilweise nach vorne von Hand herauszuziehen, wobei es insbesondere mit seiner Öse 13 durch die Ausnehmungen 10 und 11 hindurchtritt. Sodann kann die Öse 13 in den Kupplungshaken des zu kuppelnden, eine Haken-Handkupplung aufweisenden Fahrzeuges eingehängt werden. Während des Herausziehens des Ösenteiles 12 gelangt die Anschlagfläche 18 des Ringflansches 15 zumindest nahezu bis zur Anlage an der Anschlagfläche 21 des Innenflanschrings 19; bei einer nachfolgenden Zugbeanspruchung im gemischt gekuppelten Zustand wird die Zugkraft durch den geschlossenen Anschlag 18, 21 vom Ösenteil 12 auf den Kupplungskopf 1 bzw. umgekehrt übertragen. Es ist ersichtlich, daß die Kraftübertragung in Längsrichtung des Kupplungskopfes 1 erfolgt, so daß lediglich bei Kurvenfahrt der Kupplungskopf 1 um sein übliches, unter dem Bezugszeichen 22 dargestellten Anlenkgelenk am Fahrzeug geringfügig ausgelenktwird. Die Druckkräfte sind, wie bei Übergangskupplungen allgemein üblich, durch die Seitenpuffer der gekuppelten Fahrzeuge zu übertragen.In the idle state of the transition coupling, the eyelet part 12 assumes the position shown in FIG. 3, in which it is completely retracted into the recess 9 by the spring 20 and its eyelet 13 is located closely behind the coupling mouth 2. For mixed coupling, the eyelet part 12 must be partially pulled out of the coupling head 1 by hand, in particular with its eyelet 13 passing through the recesses 10 and 11. The eyelet 13 can then be hooked into the coupling hook of the vehicle to be coupled, which has a hook hand coupling. During the pulling out of the eyelet part 12, the stop surface 18 of the ring flange 15 at least almost comes to rest against the stop surface 21 of the inner flange ring 19; in the event of a subsequent tensile load in the mixed coupled state, the tensile force is transmitted by the closed stop 18, 21 from the eyelet part 12 to the coupling head 1 or vice versa. It can be seen that the power transmission takes place in the longitudinal direction of the coupling head 1, so that only when cornering the coupling head 1 is slightly deflected around its usual articulation joint shown at 22 in the vehicle. The pressure forces are to be transmitted through the side buffers of the coupled vehicles, as is common with transition couplings.

In Abänderung zu vorstehend beschriebenen Ausführungsbeispiel ist es möglich, im Kupplungskopf 1 anstelle des Ösenteiles 12 auch den Kupplungshaken als Kupplungsteil dicht hinter dem Kupplungsmaul 2 in derAusnehmung 9 starr oder höchstens um geringe Hubwege nach vorn herausziehbar zu lagern. In diesem Fall ist beim gemischten Kuppeln die Kuppelkette des anderen Fahrzeuges in den Kupplungshaken einzuhängen, wobei die Ausnehmungen 10 und 11 den Einhängvorgang wesentlich erleichtern.In a modification of the exemplary embodiment described above, it is possible, in the coupling head 1 instead of the eyelet part 12, to also store the coupling hook as a coupling part rigidly behind the coupling mouth 2 in the recess 9 rigidly or at most so that it can be pulled out to the front by short travel distances. In this case, in the case of mixed coupling, the coupling chain of the other vehicle is to be hooked into the coupling hook, the recesses 10 and 11 making the hooking-in process considerably easier.

Bei vorstehend beschriebenen Ausführungsformen weist die Übergangskupplung nach ihrem Kuppeln zwangsläufig ein Längsspiel auf, sie ist also bei anliegenden Seitenpuffern nicht straff gespannt, wodurch sich ein unruhiges Fahrverhalten eines Zugverbandes ergeben kann. Zum Beseitigen dieses Spieles kann die Übergangskupplung mit der aus Fig. 4 und 5 ersichtlichen Anschlagvorrichtung ausgestattet werden. In Fig. 4 und 5 ist das Ösenteil 12 mit der Öse 13 und dem Schaftteil 14 dargestellt, das Schaftteil 16 mit dem Federteller 17 und die Feder 20 sind zur Vereinfachung weggelassen. Der Ringflansch 15 weist auf seiner der Anschlagfläche 18 abgewandten Seite eine vom Schaftteil durchsetzte Keilfläche 23 auf, welcher im dargestellten, spielbehafteten gemischten Kupplungszustand nach rückwärts versetzt eine Keilfläche. 24 eines Zwischenteiles 25 gegenübersteht. Das Zwischenteil 25 ist im Kupplungskopf 1 querverschieblich zum Ösenteil 12 gelagert, wobei es nach vorne über kräftige Führungen 26 abgestützt ist. Das Zwischenteil 25 ist gegabelt und umgreift den Schaftteil des Ösenteiles 12; eine Feder 27 hält es in der dargestellten Lage, von Hand ist es mittels eines Handgriffes 28 aus dieser Lage gegen die Kraft der Feder 27 zur Seite verschiebbar, so daß es aus der Bewegungsbahn des Ringflansches 15 austritt. Die Rückseite des Zwischenteiles 25 ist zu einer Anschlagfläche 29 ausgebildet.In the above-described embodiments, the transition coupling inevitably has a longitudinal play after it has been coupled, that is to say it is not tightly tensioned in the case of adjacent side buffers, which can result in an uneven driving behavior of a train set. To eliminate this play, the transition coupling can be equipped with the stop device shown in FIGS. 4 and 5. 4 and 5, the eyelet part 12 with the eyelet 13 and the shaft part 14 is shown, the shaft part 16 with the spring plate 17 and the spring 20 are omitted for simplicity. The ring flange 15 has on its side facing away from the abutment surface 18 a wedge surface 23 penetrated by the shaft part, which in the illustrated, playful, mixed coupling state displaces a wedge surface to the rear. 24 faces an intermediate part 25. The intermediate part 25 is mounted in the coupling head 1 so as to be displaceable in relation to the eyelet part 12, whereby it is supported at the front by strong guides 26. The intermediate part 25 is forked and engages around the shaft part of the eyelet part 12; a spring 27 holds it in the position shown, by hand it can be moved from this position to the side against the force of the spring 27 by means of a handle 28, so that it emerges from the path of movement of the ring flange 15. The back of the intermediate part 25 is formed into a stop surface 29.

Wird, ausgehend vom dargestellten Zustand mit lose gekuppelter Übergangskupplung, durch kurze, schwache Druckbelastung der Übergangskupplung das Ösenteil 12 zurückgedrückt, so gelangen die Keilfläche 23 und 24 zum Eingriff und das Zwischenteil 25 wird gegen die Kraft der Feder 27 zur Seite gedrückt. Der Ringflansch 15 kann dann am Zwischenteil 25 vorbei nach rückwärts gleiten, woraufhin das Zwischenteil unter der Kraft der Feder 27 wieder in die dargestellte Lage schnappt. Die Öse 13 ist dabei in eine zurückversetzte Lage gelangt. Die Anschlagfläche 18 steht nun nicht mehr der Anschlagfläche 21, sondern der Anschlagfläche 29 gegenüber, bei einer nachfolgenden Zugbelastung werden die Zugkräfte somit vom Ösenteil 12 über die Anschlagflächen 18 und 29 sowie das Zwischenteil 25 und die Führungen 26 auf den' Kupplungskopf 1 übertragen. Durch die erwähnte, zurückversetzte Lage der Öse 13 ist dabei das Spiel in der gekuppelten Übergangskupplung beseitigt, so daß eine ruhige, stoßfreie Fahrt des Zugverbandes möglich ist.If, starting from the state shown with a loosely coupled transition coupling, the eyelet part 12 is pushed back by a short, weak pressure load on the transition coupling, the wedge surfaces 23 and 24 come into engagement and the intermediate part 25 is pressed to the side against the force of the spring 27. The annular flange 15 can then slide past the intermediate part 25 backwards, whereupon the intermediate part snaps back into the position shown under the force of the spring 27. The eyelet 13 has reached a set-back position. The stop surface 18 is now no longer opposite the stop surface 21 but the stop surface 29, with a subsequent tensile load the tensile forces are thus transmitted from the eyelet part 12 via the stop surfaces 18 and 29 as well as the intermediate part 25 and the guides 26 to the coupling head 1. Due to the above-mentioned, recessed position of the eyelet 13, this is Eliminated play in the coupled transition coupling, so that a smooth, shock-free journey of the train set is possible.

Zum gemischten Kuppeln ist, ausgehend vom Ruhezustand, das Ösenteil 12 mittels eines unter dem Bezugszeichen 30 angedeuteten Handgriffes unter gleichzeitigem, manuellem Verschieben des Zwischenteiles 25 zur Seite in die in Fig. 4 dargestellte Stellung zu bringen, woraufhin die Öse 13 ohne Schwierigkeiten in den Kupplungshaken der Hakenkupplung einzuhängen ist. Bei Freigabe des Zwischenteiles 25 drückt die Feder 27 dieses in die dargestellte Lage, damit ist der spielbehaftete Gemischtkupplungszustand erreicht. Zum Entkuppeln beim spielfreien Gemischtkupplungszustand ist es zweckmäßig, anfänglich ebenfalls das Zwischenteil 25 zur Seite zu schieben, was jedenfalls unter geringer Druckbelastung der Übergangskupplung möglich ist, woraufhin das Ösenteil 12 in die in Fig. 4 dargestellte Stellung nach vorne gezogen und infolge des nunmehr vorhandenen Spieles ohne weiteres aus dem Kupplungshaken ausgehängt werden kann. Nach Freigabe des Ösenteiles 12 kehrt dieses unter der Kraft der Feder 20 unter kurzzeitigem, seitlichen Auslenken des Zwischenteiles 25 in seine Ruhelage zurück.For mixed coupling, starting from the idle state, the eyelet part 12 is to be moved to the position shown in FIG. 4 by means of a handle indicated by the reference numeral 30 with simultaneous manual displacement of the intermediate part 25, whereupon the eyelet 13 is easily inserted into the coupling hook the hook coupling is to be attached. When the intermediate part 25 is released, the spring 27 presses it into the position shown, so that the mixed coupling state with play is reached. For uncoupling in the play-free mixed coupling state, it is expedient to initially also push the intermediate part 25 to the side, which is possible in any case with little pressure load on the transition coupling, whereupon the eyelet part 12 is pulled forward into the position shown in FIG. 4 and as a result of the play which is now present can be easily detached from the coupling hook. After the release of the eyelet part 12, it returns to its rest position under the force of the spring 20 with a brief lateral deflection of the intermediate part 25.

Insbesondere im Rangierbetrieb kann es zweckmäßig sein, wenn im gemischt gekuppelten Zustand ein Kupplungsspiel vorhanden ist, also nicht selbsttätig geschaltet wird. Hierzu ist es zweckmäßig, einen in Längsrichtung der Kupplung verschieblichen, zum Ösenteil 12 zur Seite versetzten Riegel 31 vorzusehen. Der Riegel 31 kann mittels eines Handgriffes 32 manuell entgegen der Kraft einer Feder 33 bei zur Seite ausgelenktem Zwischenteil 25 nach vorne geschoben werden, wobei er sich mit einer abgeschrägten Haltefläche 34 gegen eine entsprechende Gegenfläche 35 an einer Hinterschneidung des Zwischenteiles 25 einhakt. Bei freigegebenem Zwischenteil 25 wird dieses durch den Riegel 31 in seiner ausgelenkten Lage gehalten, wobei die Schräganordnungen der Haltefläche 34 und Gegenfläche 35 den Riegel 31 ebenfalls in seiner eingedrückten Lage festhalten. Das Zwischenteil 25 wird somit in seiner unwirksamen Lage festgehalten und die Kupplungszugkräfte können vom Ösenteil 12 nur über den Anschlag 18, 21 auf den Kupplungskopf 1 übertragen werden. Ein selbsttätiges Ausschalten des Kupplungsspieles ist ausgeschlossen. Erst beim manuellen Herausziehen des Riegels 31 in die dargestellte Lage oder bei einem kurzen, zusätzlichen, seitlichen Auslenken des Zwischenteiles 25, bei welchem die Haltefläche 34 und die Gegenfläche 35 außer Eingriff gelangen und der Riegel 31 somit selbsttätig unter der Kraft der Feder 33 in die dargestellte Lage zurückschnappt, wird das Zwischenteil 25 wieder frei und die Feder 27 schiebt es infolgedessen in die dargestellte Lage. Erst nachfolgend kann ein Kupplungsspiel wieder selbsttätig ausgeschaltet werden. Der Riegel 31 ist also nur unter Last selbsthaltend ausgebildet.In shunting mode in particular, it can be expedient if there is a clutch play in the mixed coupled state, that is to say it is not switched automatically. For this purpose, it is expedient to provide a bolt 31 which is displaceable in the longitudinal direction of the coupling and offset to the side with respect to the eyelet part 12. The latch 31 can be pushed forward by means of a handle 32 against the force of a spring 33 with the intermediate part 25 deflected to the side, whereby it hooks with an inclined holding surface 34 against a corresponding counter surface 35 on an undercut of the intermediate part 25. When the intermediate part 25 is released, it is held in its deflected position by the bolt 31, the inclined arrangements of the holding surface 34 and counter surface 35 likewise holding the bolt 31 in its pressed-in position. The intermediate part 25 is thus held in its inactive position and the coupling tensile forces can only be transmitted from the eyelet part 12 to the coupling head 1 via the stop 18, 21. The clutch play cannot be switched off automatically. Only when the bolt 31 is pulled out manually into the position shown or in the event of a brief, additional, lateral deflection of the intermediate part 25, in which the holding surface 34 and the counter surface 35 disengage and the bolt 31 thus automatically under the force of the spring 33 into the snaps back position shown, the intermediate part 25 is free again and the spring 27 consequently pushes it into the position shown. Only then can a clutch play be switched off again automatically. The latch 31 is therefore designed to be self-locking only under load.

Es ist selbstverständlich, daß auch hierbei anstelle des Ösenteiles 12 ein Hakenteil 36 vorgesehen sein kann, wie es die Figuren 6 und 7 andeuten. An den abgebrochen dargstellten Schaft 37 des Hakenteiles 36 schließt sich somit die in Fig. 4 und 5 dargestellte Anschlagvorrichtung an.It goes without saying that a hook part 36 can also be provided instead of the eyelet part 12, as indicated in FIGS. 6 and 7. The stop device shown in FIGS. 4 and 5 thus adjoins the shaft 37 of the hook part 36 shown broken off.

Das Zwischenteil 25 kann in einer beliebigen, nicht nur wie aus dem Ausführungsbeispiel entnehmbar in horizontaler Richtung quer zur Längsrichtung des Ösenteils 12 verschieblich sein.The intermediate part 25 can be displaceable in any direction, not only as can be seen in the exemplary embodiment, in the horizontal direction transverse to the longitudinal direction of the eyelet part 12.

In weiterer Abänderung kann bei schmaler Ausbildung der Übergangskupplung die Ausnehmung 11 entfallen, wenn die Ausnehmungen 9 und 10 für den Durchtritt bzw. die Zugänglichkeit des Ösen- bzw. Hakenteils ausreichen.In a further modification, the recess 11 can be omitted if the transition coupling is narrow, if the recesses 9 and 10 are sufficient for the passage or accessibility of the eyelet or hook part.
