Description

Beschreibungdescription

Die Erfindung betrifft eine Übergangskupplung gemäß dem Oberbegriff des unabhängigen Patentanspruches 1.The invention relates to a transition coupling according to the preamble of the independent claim 1.

Demgemäß betrifft die Erfindung insbesondere eine Übergangskupplung zum Adaptieren von Kupplungen unterschiedlicher Bauart, wobei die Übergangskupplung eine erste Verbindungseinrichtung zum lösbaren Verbinden der Übergangskupplung mit einer ersten Kupplung, eine zweite Verbindungseinrichtung zum lösbaren Verbinden der Übergangskupplung mit dem Zughaken einer zweiten Kupplung und einen Kupplungsträger zum Verbinden der ersten Verbindungseinrichtung mit der zweiten Verbindungseinrichtung aufweist, wobei die zweite Verbindungseinrichtung einen Zugbügel aufweist, wobei der Zugbügel einen ersten und einen zweiten Träger aufweist, welche mit einem Zugbolzen derart verbunden sind, dass eine Aufnahme ausgebildet wird zum Aufnehmen des Zughakens der zweiten Kupplung.Accordingly, the invention particularly relates to a transitional coupling for adapting couplings of different types, wherein the transitional coupling comprises a first connecting means for releasably connecting the transitional coupling with a first clutch, a second connecting means for releasably connecting the transitional coupling with the towing hook of a second clutch and a coupling support for connecting the first connecting device with the second connecting device, wherein the second connecting device comprises a clamping yoke, wherein the clamping yoke has a first and a second carrier, which are connected to a tie bolt such that a receptacle is formed for receiving the towing hook of the second coupling.

Beispielsweise betrifft die Erfindung eine Übergangskupplung zum gemischten Kuppeln zwischen einer automatischen Mittelpufferkupplung und einer Schraubenkupplung, wobei der erste Verbindungsbereich der Übergangskupplung als Kuppelverschluss ausgebildet sein kann zum lösbaren Verbinden der Übergangskupplung mit dem Kupplungskopf einer automatischen Mittelpufferkupplung, und wobei der zweite Verbindungsbereich der Übergangskupplung als ein in den Zughaken einer Schraubenkupplung einsetzbaren Kupplungsbügel ausgebildet sein kann zum lösbaren Verbinden der Übergangskupplung mit dem Kupplungskopf einer Schraubenkupplung.For example, the invention relates to a transition coupling for mixed coupling between an automatic central buffer coupling and a screw coupling, wherein the first connection region of the transition coupling may be formed as a dome closure for releasably connecting the transition coupling with the coupling head of an automatic central buffer coupling, and wherein the second connection region of the transition coupling as a in the tow hook of a screw coupling usable coupling bracket may be formed for releasably connecting the transitional coupling with the coupling head of a screw coupling.

Unter dem hierin verwendeten Begriff "Verbindungsbereich" ist allgemein eine Schnittstelle zwischen dem Kupplungsträger der Übergangskupplung einerseits und der mit der Übergangskupplung zu verbindenden Kupplung andererseits zu verstehen. Der Verbindungsbereich kann beispielsweise als Kuppelverschluss ausgebildet sein bzw. einen Kuppelverschluss aufweisen zum lösbaren Verbinden der Übergangskupplung mit dem Kupplungskopf einer automatischen Mittelpufferkupplung. Andererseits ist es denkbar, dass der Verbindungsbereich einen Kupplungsbügel aufweist, der in den Zughaken einer Schraubenkupplung einsetzbar ist. Selbstverständlich kommen für den Verbindungsbereich aber auch andere Ausführungsformen in Frage.The term "connection area" as used herein generally means an interface between the coupling support of the transition coupling on the one hand and the coupling to be connected to the transition coupling on the other hand. The connection region may be formed, for example, as a dome closure or have a dome closure for releasably connecting the transition coupling with the coupling head of an automatic central buffer coupling. On the other hand, it is conceivable that the connecting portion has a coupling bracket, which is insertable in the towing hook of a screw coupling. Of course, come for the connection area but other embodiments in question.

Eine gattungsgemäße Übergangskupplung ist allgemein aus der Schienenfahrzeugtechnik bekannt und wird eingesetzt, um Schienenfahrzeuge zu verbinden, die mit unterschiedlichen Kupplungssysternen ausgestattet sind (z.B. Scharfenberg®-Kupplung auf Zughaken). Das Aufsetzen der Übergangskupplung beispielsweise auf den Zughaken erfolgt in der Regle manuell, während der Kuppelvorgang mit der Mittelpufferkupplung automatisch stattfinden kann.A generic transition coupling is generally known from rail vehicle technology and is used to connect rail vehicles that are equipped with different clutch systems (eg Scharfenberg ® coupling on towing hook). The placement of the transition coupling, for example, on the tow hook is done manually in the rule, while the coupling process can take place automatically with the central buffer coupling.

Eine ebenfalls gattungsgemäße Druckschrift FR 2 473 447 A1 betrifft eine Übergangskupplung, die zum Adaptieren einer Schraubenkupplung mit einer Mittelpufferkupplung vom Typ Scharfenberg geeignet ist. Bei diesem Stand der Technik erfolgt die Höhenzentrierung über beidseitig an der Übergangskupplung angeordnete Winkelhebel, wobei ein erster Lenker des Winkelhebels teleskopartig verschiebbar und ein zweiter Lenker des Winkelhebels als starrer Lenker ausgebildet sind. Durch das Vorsehen des Winkelhebels kann bei der bekannten Übergangskupplung eine Höhenzentrierung realisiert werden. Allerdings ist die manuelle Handhabung, und insbesondere das manuelle Einsetzen der Übergangskupplung in die Schnittstelle zwischen den zu adaptierenden Kupplungen, wie beispielsweise in den Zughaken einer Schraubenkupplung, erschwert, da es für einen Bediener nicht möglich ist, einerseits das Gewicht der Übergangskupplung zu halten und andererseits die Vorrichtung zur Höhenzentrierung in korrekter Weise am Zughaken anzubringen.A likewise generic publication FR 2 473 447 A1 relates to a transitional coupling suitable for adapting a screw coupling to a Scharfenberg type central buffer coupling. In this prior art, the height is centered on both sides of the transition coupling arranged angle lever, wherein a first arm of the angle lever telescopically displaceable and a second arm of the angle lever are designed as a rigid arm. By providing the angle lever, a height centering can be realized in the known transitional coupling. However, the manual handling, and in particular the manual insertion of the transitional coupling in the interface between the couplings to be adapted, such as in the towing hook of a screw coupling, difficult because it is not possible for an operator to keep the weight of the transition coupling on the one hand and on the other hand the device for leveling in the correct manner to attach the tow hook.

Die Druckschrift GB 899 772 A betrifft eine Übergangskupplung, welche zum Abfangen und zur Dämpfung von Stoß- und Druckkräften Federelemente aufweist.The publication GB 899 772 A relates to a transitional coupling, which has spring elements for intercepting and damping shock and pressure forces.

Eine herkömmliche Übergangskupplung zum gemischten Kuppeln zwischen einer automatischen Mittelpufferkupplung und beispielsweise einer Schraubenkupplung weist in der Regel einen zumindest bereichsweise als Gehäuse ausgebildeten Kupplungsträger auf, in welchem als erste Verbindungseinrichtung ein Kuppelverschluss aufgenommen sein kann zum mechanischen Verbinden der Übergangskupplung mit einem in dem Kupplungskopf einer automatischen Mittelpufferkupplung vorgesehenen Kuppelverschluss. Im gekuppelten Zustand liegt dann die Stirnfläche der Übergangskupplung an der Stirnfläche des Kupplungskopfes der automatischen Mittelpufferkupplung an.A conventional transition coupling for mixed coupling between an automatic central buffer coupling and, for example, a screw coupling usually has a clutch carrier formed at least partially as a housing, in which a dome closure can be accommodated as first connection means for mechanically connecting the transitional clutch to an in the coupling head of an automatic central buffer coupling provided dome closure. In the coupled state then lies on the end face of the transition coupling on the end face of the coupling head of the automatic central buffer coupling.

An dem der Stirnfläche der Übergangskupplung gegenüberliegenden Ende kann als zweite Verbindungseinrichtung ein Kupplungsbügel vorgesehen sein, welcher beispielsweise in den Zughaken einer Schraubenkupplung aufnehmbar ist und demnach eine mechanische Verbindung der Übergangskupplung mit der Schraubenkupplung gewährleisten kann.At the end opposite the end face of the transition coupling may be provided as a second connection means a coupling bracket, which is for example in the tow hook of a screw can be received and therefore can ensure a mechanical connection of the transition coupling with the screw coupling.

Im Betrieb werden von dem Zughaken der Schraubenkupplung Zug- und Druckkräfte in die als Kupplungsbügel ausgebildete zweite Verbindungseinrichtung der Übergangskupplung eingeleitet. Die in den Kupplungsbügel bzw. zweite Verbindungseinrichtung eingeleiteten Druckkräfte werden über den Kupplungsträger zur Stirnfläche der Übergangskupplung geleitet und von dort auf die Stirnfläche des mit der Übergangskupplung mechanisch verbundenen Kupplungskopfes der automatischen Mittelpufferkupplung übertragen.In operation, tensile and compressive forces are introduced from the towing hook of the screw coupling into the second connecting device of the transitional coupling designed as a coupling bracket. The pressure forces introduced into the coupling yoke or second connecting device are conducted via the coupling carrier to the end face of the transitional coupling and transmitted from there to the end face of the coupling head of the automatic central buffer coupling that is mechanically connected to the transition coupling.

Andererseits werden Zugkräfte über die erste Verbindungseinrichtung, wie etwa die der automatischen Mittelpufferkupplung, übertragen. Die Kuppelverschlüsse können beispielsweise ein über einen Hauptbolzen relativ zum Kupplungsträger drehbar gelagertes Herzstück mit einer daran angelenkten Kuppelöse aufweisen. Dabei erfolgt eine Zugkraftübertragung über die jeweiligen Kuppelösen, welche in den entsprechenden Herzstücken eingreifen.On the other hand, pulling forces are transmitted via the first connecting means, such as the automatic central buffer coupling. The dome closures may, for example, have a centerpiece rotatably mounted relative to the clutch carrier via a main bolt, with a coupling eye articulated thereto. In this case, there is a tensile force transmission via the respective coupling eyes, which engage in the corresponding frogs.

An dieser Stelle sei darauf hingewiesen, dass die vorliegende Erfindung keinesfalls auf eine Übergangskupplung beschränkt ist, welche ausgelegt ist, eine automatische Mittelpufferkupplung mit einer Schraubenkupplung zu verbinden. Vielmehr betrifft die Erfindung allgemein eine Übergangskupplung zum Adaptieren von Kupplungen unterschiedlicher Bauart, wobei die Übergangskupplung eine Verbindungseinrichtung aufweist, welche kompatibel mit einer Kupplung einer ersten Bauart und ausgelegt ist, eine lösbare Verbindung mit der Kupplung der ersten Bauart auszubilden, und wobei die Übergangskupplung ferner eine zweite Verbindungseinrichtung aufweist, welche kompatibel mit einer einen Zughaken aufweisenden Kupplung einer zweiten Bauart und ausgelegt ist, eine lösbare Verbindung mit der Kupplung der zweiten Bauart auszubilden.It should be noted that the present invention is by no means limited to a transitional coupling designed to connect an automatic central buffer coupling to a screw coupling. Rather, the invention generally relates to a transitional coupling for adapting couplings of different types, wherein the transitional coupling comprises a connecting device which is compatible with a coupling of a first type and adapted to form a detachable connection with the coupling of the first type, and wherein the transition coupling further second connecting device, which is compatible with a coupling of a second type having a towing hook and designed to form a releasable connection with the coupling of the second type.

Eine aus dem Stand der Technik bekannte Übergangskupplung der eingangs genannten Art ist in Fig. 1 in einer Seitenansicht und in Fig. 2 in einer perspektivischen Ansicht dargestellt. Die Übergangskupplung 101 ist bei der dargestellten Ausführungsform auf den Zughaken 50 einer zu adaptierenden Schraubenkupplung aufgesetzt. Hierzu ist die Übergangskupplung 101 an ihrem hinteren Ende beidseitig mit parallel in einem Abstand zueinander angeordneten und gleichartig ausgebildeten Trägern 103, 103' versehen, die an den freien Enden durch einen Bolzen 104 miteinander verbunden sind, der die Übergangskupplung 101 im Maul des Zughakens 50 hält. Beidseitig an der herkömmlichen Übergangskupplung 101 ist ein Winkelhebel 105 angeordnet. Ein erster Lenker 105a des Winkelhebels 105 ist teleskopartig verschiebbar ausgebildet. Wie beispielsweise in Fig. 1 dargestellt, ist der erste Lenker 105a, welcher mit einer Druckfeder 109 in der Strecklage gehalten wird, an der Übergangskupplung 101 angelenkt. Ein zweiter Lenker 105b des Winkelhebels 105 ist als starrer Lenker ausgebildet. Der erste und zweite Lenker 105a, 105b sind an ihren jeweils freien Enden durch ein gemeinsames Joch 107 miteinander verbunden. Durch das Joch 107 ist zentrisch eine Stellmutter 106 geführt, die zur Abstützung auf der Nase des Zughakens 50 einen an der Unterseite kappenförmig ausgenommenen Steg 108 trägt. Die Lenker 105a, 105b beider Seiten der Übergangskupplung 101 sind durch eine gemeinsame Achse 110 mit- und untereinander verbunden, wobei die Achse 110 als Anlagefläche an der Stirnfläche des Zughakens 50 dient, so dass durch Verstellen des Steges 108 die vertikale Winkelstellung der Übergangskupplung 101 um den Bolzen 104 und damit die Mittellage der Übergangskupplung 101 einstellbar ist.A known from the prior art transition coupling of the type mentioned is in Fig. 1 in a side view and in Fig. 2 shown in a perspective view. The transition coupling 101 is placed in the illustrated embodiment on the towing hook 50 of a screw coupling to be adapted. For this purpose, the transition coupling 101 is provided at its rear end on both sides with parallel spaced apart and identically designed carriers 103, 103 ', which are connected at the free ends by a bolt 104 which holds the transition clutch 101 in the mouth of the towing hook 50 , On both sides of the conventional transition coupling 101, an angle lever 105 is arranged. A first link 105a of the angle lever 105 is designed to be telescopically displaceable. Such as in Fig. 1 1, the first link 105 a, which is held in the extended position by a compression spring 109, is articulated to the transition coupling 101. A second link 105b of the angle lever 105 is formed as a rigid arm. The first and second links 105a, 105b are interconnected at their respective free ends by a common yoke 107. Through the yoke 107, an adjusting nut 106 is guided centrally, which carries for supporting on the nose of the towing hook 50 on the bottom cap-shaped recessed web 108. The links 105a, 105b on both sides of the transition coupling 101 are connected by a common axis 110 and with each other, the axis 110 serves as a contact surface on the end face of the towing hook 50, so that by adjusting the web 108, the vertical angular position of the transition clutch 101 to the bolt 104 and thus the center position of the transition coupling 101 is adjustable.

Durch das Vorsehen des Winkelhebels 105 kann bei der aus dem Stand der Technik bekannten Übergangskupplung 101 eine Höhenzentrierung realisiert werden. Allerdings ist die manuelle Handhabung, und insbesondere das manuelle Einsetzen der Übergangskupplung 101 in die Schnittstelle zwischen den zu adaptierenden Kupplungen, wie beispielsweise in den Zughaken 50 einer Schraubenkupplung, erschwert, da es für einen Bediener nicht möglich ist, einerseits das Gewicht der Übergangskupplung 101 zu halten und andererseits die Vorrichtung zur Höhenzentrierung in korrekter Weise am Zughaken 50 anzubringen.By providing the angle lever 105, a height centering can be realized in the known from the prior art transition clutch 101. However, the manual handling, and in particular the manual insertion of the transition coupling 101 in the interface between the couplings to be adapted, such as in the draw hook 50 of a screw coupling, difficult because it is not possible for an operator, on the one hand the weight of the transition coupling 101 to and, on the other hand, correctly attach the height-centering device to the hitch 50.

Auf Grundlage dieser Problemstellung liegt der Erfindung die Aufgabe zugrunde, eine Übergangskupplung der eingangs genannten Art mit einer Vorrichtung zur Höhenzentrierung zu versehen, wobei trotz der Vorrichtung zur Höhenzentrierung das manuelle Handling der Übergangskupplung vereinfacht wird.Based on this problem, the invention has for its object to provide a transition coupling of the type mentioned above with a device for Höhenzentrierung, in spite of the device for leveling the manual handling of the transitional coupling is simplified.

Diese Aufgabe wird durch den Gegenstand des unabhängigen Patentanspruches 1 gelöst.This object is solved by the subject matter of independent claim 1.

Insbesondere weist demnach die erfindungsgemäße Übergangskupplung eine Vorrichtung zur Höhenzentrierung auf, welche eine mit dem Kupplungsgehäuse der Übergangskupplung verbundene Zugöse umfasst. Diese Zugöse ist relativ zu dem Zugbügel derart angeordnet und ausgebildet, dass beim Einsetzen der Übergangskupplung in das Maul des Zughakens in einem gemeinsamen Vorgang ein Eingriff des Zughakens sowohl mit dem Zugbügel als auch mit der Zugöse ausbildbar ist.In particular, therefore, the transition coupling according to the invention has a device for height centering, which comprises a connected to the clutch housing of the transition coupling drawbar. This drawbar eye is arranged and designed relative to the drawbar so that when inserting the transition coupling in the mouth of the tow hook in a common operation an engagement of the tow hook is formed with both the drawbar and with the drawbar eye.

Die mit der erfindungsgemäßen Lösung erzielbaren Vorteile liegen auf der Hand. Dadurch, dass zur Höhenzentrierung der Übergangskupplung eine mit dem Kupplungsträger der Übergangskupplung verbundene Zugöse vorgesehen ist, welche hinsichtlich des Zugbügels derart ausgebildet und ausgelegt ist, die Nase des Zughakens aufzunehmen, wenn der Zugbügel in den Zughaken eingesetzt wird, ist zum Positionieren und Montieren der Übergangskupplung an der zu adaptierenden zweiten Kupplung nur ein einzelner Arbeitsschritt notwendig. Der Zugbügel der Übergangskupplung und die zur Höhenzentrierung vorgesehene Zugöse sind derart relativ zueinander angeordnet und ausgebildet, dass beim Einsetzen der Übergangskupplung in das Maul des Zughakens der Zugbügel einen Eingriff mit dem Zughaken ausbildet und gleichzeitig die Nase des Zughakens von der Zugöse aufgenommen wird. Demnach ist es auch einer einzelnen Person mit verhältnismäßig wenig Aufwand möglich, die Übergangskupplung anzubringen, da die zur Höhenzentrierung vorgesehene Zugöse quasi automatisch die Nase des Zughakens aufnimmt, sobald der Zugbügel der Übergangskupplung in das Maul des Zughakens eingehängt wird.The achievable with the inventive solution advantages are obvious. Characterized in that for height adjustment of the transitional coupling a connected to the clutch carrier of the transition coupling drawbar is provided which is designed and designed with respect to the drawbar to receive the nose of the tow hook when the drawbar is inserted into the tow hook is for positioning and mounting the transitional coupling at the second coupling to be adapted only a single step necessary. The clamping yoke of the transitional coupling and provided for Höhenzentrierung drawbar are arranged and formed relative to each other such that upon insertion of the transitional coupling in the mouth of the towing hook of the drawbar forms engagement with the tow hook and at the same time the nose of the tow hook is received by the towing eye. Accordingly, it is also possible for a single person with relatively little effort to install the transition coupling, as provided for Höhenzinierung drawbar automatically absorbs the nose of the tow hook as soon as the drawbar of the transitional coupling is hooked into the mouth of the towing hook.

Die erfindungsgemäße Lösung zeichnet sich ferner durch die einfache Konstruktion der Vorrichtung zur Höhenzentrierung aus, so dass im Vergleich zu einer herkömmlichen Übergangskupplung (vgl. beispielsweise die in Fig. 1 bzw. Fig. 2 dargestellte Übergangskupplung) weniger Bauteile erforderlich sind, was zu einer Gewichtsreduktion der Übergangskupplung führt.The solution according to the invention is further distinguished by the simple construction of the device for height centering, so that in comparison to a conventional transition coupling (cf., for example, the in Fig. 1 respectively. Fig. 2 shown transition coupling) fewer components are required, resulting in a weight reduction of the transition coupling.

Vorteilhafte Weiterbildungen der erfindungsgemäßen Lösung sind in den abhängigen Ansprüchen angegeben.Advantageous developments of the solution according to the invention are specified in the dependent claims.

Um zu erreichen, dass in einem gemeinsamen Vorgang beim Einsetzen der Übergangskupplung in das Maul des Zughakens der Zughaken einen Eingriff mit dem Zugbügel ausbildet, während gleichzeitig die Nase des Zughakens von der Zugöse aufgenommen wird, ist es insbesondere denkbar, dass die Zugöse derart ausgebildet und relativ zu der mit dem Zugbügel ausgebildeten Aufnahme ausgerichtet ist, dass sich die Parallelprojektion der Zugöse und die Parallelprojektion der Aufnahme auf einer horizontalen Projektionsebene zumindest bereichsweise überdecken. Beispielsweise ist in einer Realisierung der erfindungsgemäßen Lösung vorgesehen, dass zur Ausbildung des Zugbügels die zweite Verbindungseinrichtung zwei vorzugsweise parallele Träger mit einem die Träger verbindenden horizontal verlaufenden Zugbolzen aufweist, wobei der Zughaken der zweiten Kupplung in dem Bereich zwischen den beiden parallelen Trägern aufnehmbar ist. Bei dieser Realisierung sollte vorzugsweise die Zugöse auf der Oberseite des Kupplungsträgers vorgesehen sein und im Wesentlichen axial zumindest teilweise mit dem Bereich zwischen den beiden Trägern fluchten. Dies erleichtert das Handling der Übergangskupplung, da die Übergangskupplung in der Regel von oben in den Zughaken einer zu adaptierenden Kupplung eingesetzt wird. Selbstverständlich sind aber auch andere Realisierungen denkbar.In order to achieve that in a common operation when inserting the transition coupling into the mouth of the towing hook of the towing hook forms an engagement with the drawbar, while the nose of the tow hook is received by the towing eye, it is particularly conceivable that the towing eye designed and is aligned relative to the trained with the yoke receptacle that overlap the parallel projection of the drawbar eye and the parallel projection of the recording on a horizontal plane of projection at least partially. For example, it is provided in an implementation of the solution according to the invention that the second connecting device has two preferably parallel support with a horizontally extending tie bolt connecting the supports to form the tie bar, wherein the tow hook of the second coupling can be received in the region between the two parallel supports. In this realization, the drawbar eye should preferably be provided on the upper side of the coupling support and be aligned substantially axially at least partially with the area between the two supports. This facilitates the handling of the transition coupling, since the transition coupling is usually inserted from above into the towing hook of a coupling to be adapted. Of course, other realizations are conceivable.

Um zu erreichen, dass in einer leicht zu realisierenden aber dennoch effektiven Weise die Höhenzentrierung der Übergangskupplung eingestellt werden kann, ist in einer bevorzugten Weiterbildung vorgesehen, dass die Zugöse über eine spezielle Mechanik derart mit dem Kupplungsträger der Übergangskupplung verbunden ist, dass zur Höhenzentrierung der Übergangskupplung die Zugöse in Längsrichtung der Übergangskupplung relativ zu dem Zugbügel bewegbar ist. Hierbei handelt es sich um eine besonders leicht zu realisierende aber dennoch effektive Lösung, um die Höhenzentrierung der Übergangskupplung umsetzen zu können. Indem die Zugöse in Längsrichtung der Übergangskupplung relativ zu dem Zugbügel in Richtung des ersten Verbindungsbereiches bewegt wird, kann über die Zugöse eine Zugkraft auf die Nase des in dem Zugbügel aufgenommenen Zughakens ausgeübt werden, was ein an der Übergangskupplung angreifendes Drehmoment und somit ein vertikales Verschwenken der Übergangskupplung relativ zu dem Zughaken um den Zugbolzen des Zugbügels zur Folge hat.In order to achieve that in an easy to implement, but effective way, the height of the transition coupling transition can be adjusted, it is provided in a preferred embodiment that the towing eye is connected via a special mechanism with the clutch carrier of the transitional coupling that the height centering of the transitional coupling the towing eye in the longitudinal direction of the transitional coupling is movable relative to the clamping yoke. This is a particularly easy to implement, yet effective solution to implement the height centering of the transition coupling. By the drawbar eye is moved in the longitudinal direction of the transitional coupling relative to the drawbar in the direction of the first connecting portion, a tensile force can be exerted on the nose of the tow hook received in the drawbar over the drawbar eye, which acts on the transition coupling torque and thus a vertical pivoting of the Transition coupling has relative to the tow hook to the draw bolt of the drawbar result.

In einer vorteilhaften Weiterbildung der zuletzt genannten Ausführungsform weist die Mechanik, mit welcher die Zugöse in Längsrichtung der Übergangskupplung relativ zu dem Zugbügel bewegbar ist, einen ersten sowie einen zweiten Anschlag auf, um die Längsbewegung der Zugöse begrenzen zu können. Auf diese Weise wird sichergestellt, dass die Übergangskupplung nur innerhalb eines vorab festlegbaren vertikalen Winkelbereiches relativ zu dem Zughaken verschwenkbar ist. Der erste und zweite Anschlag sind dabei so auszuführen, dass der zugelassene Schwenkbereich so gewählt ist, dass im Fahrbetrieb fahrdynamische Bewegungen zugelassen werden.In an advantageous development of the latter embodiment, the mechanism with which the towing eye is movable relative to the drawbar in the longitudinal direction of the transitional coupling, a first and a second stop in order to limit the longitudinal movement of the towing eye can. In this way it is ensured that the transition coupling is pivotable relative to the towing hook only within a pre-definable vertical angle range. The first and second stops are to be designed in such a way that the permissible swivel range is selected so that driving dynamic movements are permitted during driving.

In einer bevorzugten Weiterbildung der zuletzt genannten Ausführungsformen weist die Mechanik, über welche die Zugöse mit dem Kupplungsträger der Übergangskupplung verbunden ist, mindestens ein Federelement auf, um die Zugöse in Richtung der zweiten Verbindungseinrichtung vorzuspannen. Vorzugsweise ist dabei der Betrag der mit dem Federelement ausgeübten Vorspannung vorab einstellbar. Durch das Vorsehen von mindestens einem Federelement können die im Fahrbetrieb auftretenden fahrdynamischen Bewegungen abgedämpft werden.In a preferred development of the last-mentioned embodiments, the mechanism by means of which the drawbar eye is connected to the coupling support of the transition coupling has at least one spring element in order to bias the drawbar eye in the direction of the second connection device. Preferably, the amount of the bias exerted by the spring element is in advance adjustable. By providing at least one spring element, the driving dynamic movements occurring during driving can be damped.

In einer besonders bevorzugten Realisierung der Übergangskupplung weist die Mechanik, über welche die Zugöse mit dem Kupplungsträger verbunden ist, eine in Längsrichtung der Übergangskupplung relativ zu dem Zugbügel bewegbare Zugstange oder dergleichen auf, wobei die Zugöse an dem Endbereich der Zugstange befestigt ist, welcher der zweiten Verbindungseinrichtung zugewandt ist. Hierbei ist es ferner denkbar, dass ein mit dem Kupplungsträger vorzugsweise lösbar verbundener Träger vorgesehen ist, welcher eine Öffnung aufweist, durch welche die Zugstange geführt wird. Zwischen dem Träger und dem der ersten Verbindungseinrichtung zugewandten Endbereich der Zugstange ist vorzugsweise das bereits erwähnte mindestens eine Federelement angeordnet, um die Zugöse in Richtung der ersten Verbindungseinrichtung vorzuspannen.In a particularly preferred realization of the transitional coupling, the mechanism, via which the towing eye is connected to the coupling support, a movable in the longitudinal direction of the transition coupling relative to the drawbar drawbar or the like, wherein the drawbar is fixed to the end region of the drawbar, which is the second Facing connection device. In this case, it is also conceivable that a carrier which is preferably detachably connected to the clutch carrier is provided, which has an opening through which the pull rod is guided. Between the carrier and the end of the connecting rod facing the first connecting device, the already mentioned at least one spring element is preferably arranged in order to bias the drawbar eye in the direction of the first connecting device.

Besonders bevorzugt ist der Träger mit dem Kupplungsgehäuse lösbar verbunden, was beispielsweise das Nachrüsten einer Übergangskupplung mit einer Vorrichtung zur Höhenzentrierung ermöglicht.Particularly preferably, the carrier is releasably connected to the clutch housing, which allows, for example, the retrofitting of a transition coupling with a device for leveling.

Der Träger ist vorzugsweise auf der Oberseite des Kupplungsgehäuses mit dem Kupplungsgehäuse verbunden. Denkbar ist es selbstverständlich aber auch, dass der Träger seitlich des Kupplungsgehäuses mit dem Kupplungsgehäuse verbunden ist.The carrier is preferably connected to the coupling housing on the upper side of the coupling housing. It is conceivable, of course, but also that the carrier is connected to the side of the coupling housing with the coupling housing.

Im Folgenden werden Ausführungsbeispiele der Erfindung anhand der Darstellungen in den Figuren 3 bis 7 näher beschrieben.In the following, embodiments of the invention with reference to the representations in the FIGS. 3 to 7 described in more detail.

In den Figuren 1 und 2 ist eine aus dem Stand der Technik bekannte Übergangskupplung 101 gezeigt, welche zur Höhenzentrierung einen Winkelhebel 105 aufweist, der über ein Joch 107 auf der Nase eines Zughakens 50 befestigt wird. Der Winkelhebel 105 ist dabei seitlich mit dem Gehäuse 102 der Übergangskupplung 101 befestigt und gewährleistet die Höhenzentrierung der Übergangskupplung 101.In the FIGS. 1 and 2 a transition coupling 101 known from the prior art is shown, which has an angle lever 105 for height centering, which is fastened via a yoke 107 on the nose of a towing hook 50. The angle lever 105 is secured laterally with the housing 102 of the transitional coupling 101 and ensures the centering of the transitional coupling 101th

Wie bereits ausgeführt, ist ein Nachteil bei der herkömmlichen in den Figuren 1 und 2 dargestellten Übergangskupplung 101 darin zu sehen, dass aufgrund des relativ komplizierten Aufbaus der Vorrichtung zur Höhenzentrierung in Gestalt eines Winkelhebels 105 die Montage der Übergangskupplung 101 an dem Zughaken 50 einer zu adaptierenden Kupplung relativ schwer ausführbar ist. Insbesondere ist es nicht möglich, die Übergangskupplung 101 von einer Person alleine an dem Zughaken 50 einer zu adaptierenden Kupplung zu montieren, da nicht gleichzeitig von einer Person die Übergangskupplung 101 gehalten und die Vorrichtung zur Höhenzentrierung in korrekter Weise am Zughaken 50 angebracht werden kann.As already stated, a disadvantage in the conventional in the FIGS. 1 and 2 can be seen in that due to the relatively complicated structure of the device for leveling in the form of an angle lever 105, the assembly of the transitional coupling 101 on the towing hook 50 of a coupling to be adapted relatively difficult to execute. In particular, it is not possible to mount the transition coupling 101 by a person alone on the towing hook 50 of a coupling to be adapted, since not at the same time held by a person, the transition coupling 101 and the device for leveling can be correctly attached to the towing hook 50.

Um diesem Nachteile Sorge zu tragen, wird gemäß der Erfindung eine Übergangskupplung 1 vorgeschlagen, wie sie unter Bezugnahme auf die Darstellungen in den Figuren 3 bis 7 anhand von Ausführungsbeispielen im Nachfolgenden näher beschrieben wird. Im Einzelnen zeigt Fig. 3 ein erstes Ausführungsbeispiel der erfindungsgemäßen Übergangskupplung 1 in einer Seitenansicht, während in Fig. 4 die Übergangskupplung 1 gemäß der ersten Ausführungsform in einer perspektivischen Ansicht dargestellt ist.To take care of these disadvantages, a transition coupling 1 is proposed according to the invention, as with reference to the representations in the FIGS. 3 to 7 will be described in more detail below with reference to exemplary embodiments. In detail shows Fig. 3 a first embodiment of the transition coupling 1 according to the invention in a side view, while in Fig. 4 the transitional coupling 1 according to the first embodiment is shown in a perspective view.

Die in den Figuren 3 und 4 dargestellte Ausführungsform der erfindungsgemäßen Übergangskupplung 1 besteht aus einem Kupplungsgehäuse 2, welches zumindest teilweise die Kupplungsorgane der Übergangskupplung 1 aufnimmt. Im Einzelnen ist in dem Kupplungsgehäuse 2 als erste Verbindungseinrichtung ein Kuppelverschluss 5 aufgenommen, welcher zum lösbaren Verbinden der Übergangskupplung 1 mit dem Kupplungskopf einer (nicht dargestellten) automatischen Mittelpufferkupplung dient.The in the Figures 3 and 4 illustrated embodiment of the transition coupling 1 according to the invention consists of a coupling housing 2, which at least partially receives the coupling members of the transitional coupling 1. Specifically, a dome closure 5 is received in the clutch housing 2 as the first connection means, which serves for releasably connecting the transitional coupling 1 with the coupling head of an automatic central buffer coupling (not shown).

Bei der in den Figuren 3 und 4 dargestellten Ausführungsform ist die Übergangskupplung 1 ausgelegt, mit einer automatischen Mittelpufferkupplung vom Typ Scharfen-berg® zu kuppeln.In the in the Figures 3 and 4 illustrated embodiment, the transition coupling 1 is designed to couple with an automatic central buffer coupling of the type Scharfen-berg ®.

Demgemäß weist bei der dargestellten ersten Ausführungsform der in dem Kupplungsgehäuse 2 aufgenommene Kuppelverschluss 5 insbesondere ein Herzstück auf, welches über einen vertikal verlaufenden Hauptbolzen 6 relativ zum Kupplungsgehäuse 2 verdrehbar gelagert ist. An dem Herzstück ist eine Kuppelöse 7 angelenkt, die dazu dient, in ein Herzstück einer mit der Übergangskupplung 1 zu kuppelnden automatischen Mittelpufferkupplung einzugreifen.Accordingly, in the illustrated first embodiment, the dome closure 5 accommodated in the coupling housing 2 in particular has a frog which is rotatably mounted relative to the coupling housing 2 via a vertically extending main bolt 6. At the heart of a coupling eye 7 is articulated, which serves to engage in a heart of a to be coupled with the transition coupling 1 automatic central buffer coupling.

Obwohl in den Figuren 3 und 4 nicht explizit dargestellt, ist es selbstverständlich denkbar, dass der Kuppelverschluss 5 zusätzlich zu dem bereits erwähnten Herzstück, welches über den Hauptbolzen 6 drehbar im Kupplungsgehäuse 2 gelagert ist, und an welchem die Kuppelöse 7 angelenkt ist, ferner Zugfedern, Federlager und eine Klinkenstange mit Stempelführung aufweist, um ein automatisches Kuppeln und Entkuppeln der Übergangskupplung 1 mit einer automatischen Mittelpufferkupplung beispielsweise vom Typ Scharfenberg® zu gestatten. Demnach ist es bevorzugt, wenn der in dem Kupplungsgehäuse 2 aufgenommene Kuppelverschluss 5 als herkömmlicher Drehverschluss ausgebildet und ausgelegt ist, mechanisch mit dem Kupplungskopf einer automatischen Mittelpufferkupplung lösbar verbunden zu werden.Although in the Figures 3 and 4 not explicitly shown, it is of course conceivable that the dome closure 5 in addition to the already mentioned core, which is rotatably mounted on the main pin 6 in the clutch housing 2, and on which the coupling eye 7 is hinged, also tension springs, spring bearings and a pawl rod with punch guide to allow automatic coupling and decoupling of the transition coupling 1 with an automatic central buffer coupling, for example of the type Scharfenberg ® . Accordingly, it is preferred if the dome closure 5 accommodated in the coupling housing 2 is designed as a conventional rotary closure and is designed to be mechanically detachably connected to the coupling head of an automatic central buffer coupling.

Der in dem Kupplungsgehäuse 2 aufgenommene Kuppelverschluss 5 dient zur Übertragung von Zugkräften, wenn die Übergangskupplung 1 mit dem in den Figuren 3 und 4 nicht explizit dargestellten Kupplungskopf einer automatischen Mittelpufferkupplung mechanisch verbunden ist. Druckkräfte hingegen werden über die ebene Stirnfläche 11 des Kupplungsgehäuses 2 übertragen. Wie es beispielsweise in den Darstellungen in den Figuren 3 und 4 entnommen werden kann, weist hierzu das Kupplungsgehäuse 2 ein Profil bestehend aus einem breiten, ebenen Rand sowie kegel- und trichterförmig ausgebildeten Führungsflächen auf. Dieses Profil richtet die Übergangskupplung 1 in Bezug auf eine mit der Übergangskupplung 1 mechanisch zu verbindende Mittelpufferkupplung aus, zentriert diese und lässt sie auch in engen Kurven und bei Höhenversatz ineinander gleiten.The dome closure 5 accommodated in the coupling housing 2 serves to transmit tensile forces when the transition coupling 1 with the in the Figures 3 and 4 not explicitly shown coupling head of an automatic central buffer coupling is mechanically connected. Pressure forces, however, are transmitted via the flat end face 11 of the coupling housing 2. As for example in the representations in the Figures 3 and 4 can be removed, this has the coupling housing 2 has a profile consisting of a wide, flat edge and conical and funnel-shaped guide surfaces. This profile aligns the transitional coupling 1 with respect to a central buffer coupling to be mechanically connected to the transitional coupling 1, centers it and allows it to slide into one another even in tight bends and when displaced vertically.

Wie es insbesondere der Darstellung in Fig. 4 zu entnehmen ist, kann das Kupplungsgehäuse 2 der Übergangskupplung 1 eine Stirnfläche 11 aufweisen, die einstückig mit dem Kupplungsgehäuse 2 ausgebildet oder separat zu dem Kupplungsgehäuse 2 ausgebildet und über eine Schraubverbindung mit dem Kupplungsgehäuse 2 verbindbar ist. Die Stirnfläche 11 weist vorzugsweise einen Trichter zur Aufnahme der Kuppelöse einer mit der Übergangskupplung 1 mechanisch zu verbindenden automatischen Mittelpufferkupplung auf. Benachbart zu dem in der Stirnfläche 11 des Kupplungsgehäuses ausgebildeten Trichter ist bei der in den Figuren 3 und 4 dargestellten Übergangskupplung 1 ferner an der Stirnfläche 11 des Kupplungsgehäuses 2 ein Kegel 12 ausgebildet. Demnach weist die Stirnfläche 11 der Übergangskupplung 1 ein Profil auf, welches kompatibel mit dem Profil eines Kupplungskopfes einer automatischen Mittelpufferkupplung ist.As it is in particular the representation in Fig. 4 can be seen, the coupling housing 2 of the transitional coupling 1 may have an end face 11 which is integrally formed with the coupling housing 2 or formed separately to the coupling housing 2 and connected via a screw connection to the coupling housing 2. The end face 11 preferably has a funnel for receiving the coupling eye of an automatic central buffer coupling to be mechanically connected to the transition coupling 1. Adjacent to the formed in the end face 11 of the coupling housing funnel is in the in the Figures 3 and 4 illustrated transition coupling 1 further formed on the end face 11 of the coupling housing 2, a cone 12. Accordingly, the end face 11 of the transitional coupling 1 has a profile which is compatible with the profile of a coupling head of an automatic central buffer coupling.

In dem der Stirnfläche 11 des Kupplungsgehäuses 2 gegenüberliegenden Endbereich der Übergangskupplung 1 ist - wie es der Darstellung in den Figuren 3 und 4 entnommen werden kann - ein Zugbügel 8 ausgeführt, welcher in den Zughaken 50 beispielsweise einer Schraubenkupplung einsetzbar ist zum lösbaren Verbinden der Übergangskupplung 1 mit der Schraubenkupplung. Hierzu weist der der Stirnfläche 11 des Kupplungsgehäuses 2 gegenüberliegende Endbereich der Übergangskupplung 1 eine entsprechende Ausnehmung 13 auf, die auf der Längsachse L der Übergangskupplung 1 verläuft.In which the end face 11 of the coupling housing 2 opposite end portion of the transition coupling 1 is - as shown in the Figures 3 and 4 can be removed - a drawbar 8 running, which is used in the towing hook 50, for example a screw coupling for releasably connecting the transition coupling 1 with the screw coupling. For this purpose, the end face 11 of the coupling housing 2 opposite end portion of the transitional coupling 1 has a corresponding recess 13 which extends on the longitudinal axis L of the transitional coupling 1.

In dem in den Figuren 3 und 4 dargestellten ersten Ausführungsbeispiel der erfindungsgemäßen Übergangskupplung 1 sind an dem der Stirnfläche 11 des Kupplungsgehäuses 2 gegenüberliegenden Endbereich der Übergangskupplung 1 zwei in Längsrichtung der Übergangskupplung 1 verlaufende parallele Träger 3, 3' vorgesehen, die mit Hilfe eines horizontal verlaufenden Zugbolzens 4 miteinander verbunden sind, um am Endbereich der Übergangskupplung 1 den Zugbügel 8 auszubilden. Der Zughaken 50 der Schraubenkupplung ist mit dem Zugbügel 8 in Eingriff bringbar, indem - wie in den Figuren 3 und 4 dargestellt - der Zughaken 50 in der Ausnehmung 13 zwischen den beiden parallelen Trägern 3, 3' aufgenommen wird.In the in the Figures 3 and 4 shown first embodiment of the transition coupling 1 according to the invention are at the end face 11 of the coupling housing 2 opposite end portion of the transition coupling 1 two in Longitudinal direction of the transitional coupling 1 extending parallel support 3, 3 'is provided, which are connected to each other by means of a horizontally extending tie bolt 4 to form the drawbar 8 at the end portion of the transitional coupling 1. The hitch 50 of the screw coupling is engageable with the clamping yoke 8 by - as in the Figures 3 and 4 shown - the tow hook 50 is received in the recess 13 between the two parallel beams 3, 3 '.

Selbstverständlich ist es nicht zwingend erforderlich, dass die beiden Träger 3, 3' parallel zueinander ausgerichtet sind. Insbesondere ist es denkbar, dass diese zueinander leicht schräg verlaufen.Of course, it is not absolutely necessary that the two carriers 3, 3 'are aligned parallel to one another. In particular, it is conceivable that these are slightly inclined to each other.

Um zu erreichen, dass sich die Übergangskupplung 1 für ein reibungsloses Kuppeln in vertikaler Nulllage einstellt und diese Position beim Kuppeln gehalten wird, weist die Übergangskupplung 1 eine Höhenzentrierung auf. Ein wesentlicher Bestandteil dieser Höhenzentrierung ist eine mit dem Kupplungsgehäuse 2 verbundene Zugöse 14, die - wie in den Figuren 3 und 4 dargestellt - zumindest bereichsweise mit der Ausnehmung 13 des Zugbügels 8 fluchtet und dazu dient, zumindest die Nase des Zughakens 50 aufzunehmen, wenn der Zughaken 50 der zu adaptierenden Kupplung mit dem Zugbügel 8 der Übergangskupplung 1 in Eingriff steht. Im Einzelnen und wie es insbesondere der Darstellung in Fig. 4 entnommen werden kann, ist bei dem Ausführungsbeispiel die Zugöse 14 auf der Oberseite des Kupplungsgehäuses 2 vorgesehen und fluchtet im Wesentlichen axial zumindest bereichsweise mit dem Bereich zwischen den beiden parallelen Trägern 3, 3', die den Zugbügel 8 am Endbereich der Übergangskupplung 1 ausbilden. Durch diese Maßnahme kann erreicht werden, dass die Nase des Zughakens 50 selbstständig in der Zugöse 14 der Höhenzentrierung aufgenommen wird, wenn der Zugbügel 8 der Übergangskupplung 1 in den Zughaken 50 der zu adaptierenden Schraubenkupplung eingesetzt wird.In order to achieve that the transitional clutch 1 is set for a smooth coupling in the vertical zero position and this position is maintained when coupling, the transition coupling 1 has a height centering. An essential part of this height-centering is connected to the coupling housing 2 drawbar eye 14, which - as in the Figures 3 and 4 shown - at least partially aligned with the recess 13 of the drawbar 8 and serves to accommodate at least the nose of the towing hook 50 when the towing hook 50 of the coupling to be adapted to the drawbar 8 of the transitional coupling 1 is engaged. In detail and how it in particular the representation in Fig. 4 can be removed, in the embodiment, the drawbar eye 14 is provided on the upper side of the coupling housing 2 and substantially axially aligned at least partially with the area between the two parallel beams 3, 3 ', which form the clamping yoke 8 at the end portion of the transitional coupling 1. By this measure it can be achieved that the nose of the tow hook 50 is automatically absorbed in the drawbar eye 14 of the Höhenzentrierung when the drawbar 8 of the transitional coupling 1 is inserted into the draw hook 50 of the screw to be adapted.

Der Darstellung in Fig. 3 ist zu entnehmen, dass bei dem ersten Ausführungsbeispiel der erfindungsgemäßen Übergangskupplung 1 die Zugöse 14 derart ausgebildet und relativ zu der mit dem Zugbügel 8 ausgebildeten Aufnahme ausgerichtet ist, dass sich die Parallelprojektion P1 der Zugöse 14 und die Parallelprojektion P2 der Aufnahme auf einer horizontalen Projektionsebene zumindest bereichsweise überdecken. Die Überdeckung ist in Fig. 3 mit der Bezugsziffer "P3" bezeichnet.The representation in Fig. 3 It can be seen that in the first embodiment of the transition coupling 1 according to the invention the drawbar eye 14 is formed and aligned relative to the trained with the yoke 8 recording, that the parallel projection P1 of the drawbar eye 14 and the parallel projection P2 recording on a horizontal projection plane at least partially overlap. The overlap is in Fig. 3 designated by the reference numeral "P3".

Bei der in den Figuren 3 und 4 dargestellten Ausführungsform ist im Einzelnen die Zugöse 14 der Höhenzentrierung über eine Mechanik derart mit dem Kupplungsgehäuse 2 der Übergangskupplung 1 verbunden, dass zur Höhenzentrierung der Übergangskupplung 1 die Zugöse 14 in Längsrichtung L der Übergangskupplung 1 relativ zu dem Zugbügel 8 bewegbar ist. Bei dem dargestellten Ausführungsbeispiel kommt hierfür eine in Längsrichtung L der Übergangskupplung 1 relativ zu dem Zugbügel 8 bewegbare Zugstange 15 zum Einsatz, wobei die Zugöse 14 an dem der Schraubenkupplung zugewandten Endbereich der Zugstange 15 befestigt ist. Diese Zugstange 15 selber verläuft im Wesentlichen parallel zur Längsrichtung L der Übergangskupplung 1. Die Zugstange 15 zusammen mit dem an einem Endbereich der Zugstange 15 befestigten Zugbügel 8 ist in Längsrichtung L der Übergangskupplung 1 relativ zu dem Zugbügel 8 bewegbar. Hierzu wird die Zugstange 15 durch eine in einem mit dem Kupplungsgehäuse 2 verbundenen Träger 16 vorgesehene Öffnung 17 geführt. Der Träger 16 selber ist bei dem dargestellten Ausführungsbeispiel der erfindungsgemä-βen Übergangskupplung 1 mit Hilfe einer Schraubverbindung 18 lösbar an der Oberseite des Kupplungsgehäuses 2 befestigt. Selbstverständlich ist es aber auch denkbar, dass der Träger 16 an der Oberseite des Kupplungsgehäuses 2 angeschweißt oder andersartig befestigt ist.In the in the Figures 3 and 4 illustrated embodiment, the drawbar eye 14 of the height centering is in detail such a mechanism with the coupling housing 2 of the transitional coupling 1 connected to the height of the transition coupling 1, the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 relative to the clamping yoke 8 is movable. In the illustrated embodiment, a drawbar 15 movable in the longitudinal direction L of the transitional coupling 1 relative to the clamping yoke 8 is used for this purpose, the drawbar eye 14 being fastened to the end region of the drawbar 15 facing the screw coupling. This tie rod 15 itself extends substantially parallel to the longitudinal direction L of the transitional coupling 1. The tie rod 15 together with the attached to an end portion of the tie rod 15 drawbar 8 is movable in the longitudinal direction L of the transitional coupling 1 relative to the drawbar 8. For this purpose, the pull rod 15 is guided by an opening 17 provided in a carrier 16 connected to the coupling housing 2. The carrier 16 itself is in the illustrated embodiment of the inventive βen transition coupling 1 by means of a screw 18 releasably secured to the top of the coupling housing 2. Of course, it is also conceivable that the carrier 16 is welded to the top of the coupling housing 2 or otherwise secured.

Wie in den Figuren 3 und 4 dargestellt, ist die Bewegung der Zugöse 14 in Längsrichtung L der Übergangskupplung 1 relativ zu dem Zugbügel 8 mit Hilfe eines ersten Anschlages 19.1 einerseits und eines zweiten Anschlages 19.2 andererseits begrenzt. Der erste Anschlag 19.1 ist an dem der Schraubenkupplung zugewandten Endbereich der Zugstange 15 vorgesehen. Der zweite Anschlag 19.2 wird durch eine Mutter 20 gebildet, die an dem gegenüberliegenden Endbereich der Zugstange 15 aufgeschraubt ist. Im Einzelnen wird die Bewegung der Zugöse 14 in Längsrichtung L der Übergangskupplung 1 relativ zu dem Zugbügel 8 einerseits dadurch begrenzt, dass der erste Anschlag 19.1 gegen die Vorderseite des Trägers 16 stößt. Andererseits wird die Bewegung der Zugöse 14 in Längsrichtung L der Übergangskupplung 1 durch den zweiten Anschlag 19.2 begrenzt, der gegen die zugewandte Stirnfläche des Trägers 16 stößt.As in the Figures 3 and 4 illustrated, the movement of the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 is limited relative to the drawbar 8 by means of a first stop 19.1 on the one hand and a second stop 19.2 on the other. The first stop 19.1 is provided at the end of the drawbar 15 facing the screw coupling. The second stop 19.2 is formed by a nut 20 which is screwed to the opposite end region of the tie rod 15. In detail, the movement of the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 relative to the drawbar 8 is limited on the one hand by the fact that the first stop 19.1 abuts against the front side of the support 16. On the other hand, the movement of the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 is limited by the second stop 19.2, which abuts against the facing end face of the carrier 16.

Um zu erreichen, dass bei der erfindungsgemäßen Lösung die Höhenzentrierung im Fahrbetrieb fahrdynamische Bewegungen relativ zwischen der Übergangskupplung 1 und einer Schraubenkupplung dämpfend ausgleichen kann, weist die Höhenzentrierung ferner ein Federelement 21 in Gestalt einer Druckfeder auf. Im Einzelnen ist bei der in den Figuren 3 und 4 dargestellten Ausführungsform das Federelement 21 zwischen der Mutter 20 und dem Träger 16 vorgespannt.In order to achieve that in the solution according to the invention, the height centering during driving dynamic movements relative between the transitional coupling 1 and a screw coupling can compensate dampening, the height centering further comprises a spring element 21 in the form of a compression spring. In detail is in the in the Figures 3 and 4 illustrated embodiment, the spring element 21 biased between the nut 20 and the carrier 16.

Durch Verstellen der Mutter 20 wird durch die von dem Federelement auf den Träger 16 ausgeübte Druckkraft die Zugstange 15 zusammen mit der daran befestigten Zugöse 14 relativ zu dem Kupplungsgehäuse 2 in Längsrichtung L der Übergangskupplung 1 verschoben. Auf diese Weise kann die vertikale Winkelstellung der Übergangskupplung 1 um den Bolzen 4 und damit die Mittellage der Übergangskupplung 1 eingestellt werden.By adjusting the nut 20, the pull rod 15 is displaced relative to the coupling housing 2 in the longitudinal direction L of the transitional coupling 1 together with the attached thereto drawbar eye 14 by the force exerted by the spring element on the carrier 16 compressive force. In this way, the vertical angular position of the transitional coupling 1 can be adjusted by the bolt 4 and thus the center position of the transition coupling 1.

Nachfolgend wird unter Bezugnahme auf die Darstellungen in den Figuren 5 bis 7 eine zweite Ausführungsform der erfindungsgemäßen Übergangskupplung 1 beschrieben. Im Einzelnen ist die zweite Ausführungsform der Übergangskupplung 1 in den Figuren 5a und 5b jeweils in einer perspektivischen Darstellung gezeigt. Eine Seitenansicht der Übergangskupplung 1 gemäß dem zweiten Ausführungsbeispiel ist in Fig. 6 gezeigt, während Fig. 7 eine Draufsicht auf diese Übergangskupplung 1 zeigt.The following is with reference to the representations in the FIGS. 5 to 7 a second embodiment of the transition coupling 1 according to the invention described. In detail, the second embodiment of the transition coupling 1 in the FIGS. 5a and 5b each shown in a perspective view. A side view of the transitional coupling 1 according to the second embodiment is shown in FIG Fig. 6 shown while Fig. 7 a plan view of this transitional coupling 1 shows.

Die Übergangskupplung 1 gemäß dem zweiten Ausführungsbeispiel ist in struktureller und funktioneller Hinsicht ähnlich zum ersten Ausführungsbeispiel ausgeführt. Der Unterschied zwischen der Übergangskupplung 1 gemäß dem zweiten Ausführungsbeispiel und der Übergangskupplung gemäß dem ersten Ausführungsbeispiel ist insbesondere darin zu sehen, dass bei dem zweiten Ausführungsbeispiel die Lage der Höhenjustierung in Bezug zu dem Kupplungsgehäuse 2 der Übergangskupplung 1 verschieden ausgeführt ist. Im Einzelnen verläuft bei dem zweiten Ausführungsbeispiel die Zugstange 15 nicht mehr horizontal, wie bei dem ersten Ausführungsbeispiel, sondern leicht schräg. Nach wie vor ist die Zugöse 14 allerdings derart ausgebildet und relativ zu der mit dem Zugbügel 8 ausgebildeten Aufnahme ausgerichtet, dass sich die Parallelprojektion P2 der Zugöse 14 und die Parallelprojektion P1 der Aufnahme auf einer horizontalen Projektionsebene bereichsweise überdecken, wie es der Darstellung in Fig. 6 zu entnehmen ist.The transitional coupling 1 according to the second embodiment is executed structurally and functionally similar to the first embodiment. The difference between the transitional clutch 1 according to the second embodiment and the transitional clutch according to the first embodiment is particularly seen in the fact that in the second embodiment, the position of the height adjustment with respect to the clutch housing 2 of the transitional clutch 1 is made different. Specifically, in the second embodiment, the pull rod 15 is no longer horizontal, as in the first embodiment, but slightly inclined. As before, however, the drawbar eye 14 is designed and aligned relative to the receptacle 8 formed with the receptacle that overlap the parallel projection P2 of the drawbar eye 14 and the parallel projection P1 of the recording on a horizontal projection plane partially, as shown in the Fig. 6 can be seen.

Die weiteren Komponenten der Übergangskupplung 1 gemäß der zweiten Ausführungsform entsprechen im Übrigen den Komponenten der ersten Ausführungsform, so dass zur Vermeidung von Wiederholungen an dieser Stelle auf die vorherigen Ausführungen verwiesen wird.The other components of the transition coupling 1 according to the second embodiment, moreover, correspond to the components of the first embodiment, so that reference is made to avoid repetition at this point to the previous statements.

Obwohl in den Zeichnungen nicht dargestellt, ist es in einer Abwandlung denkbar, dass der Träger 16 nicht auf der Oberseite des Kupplungsgehäuses 2, sondern seitlich des Kupplungsgehäuses 2 mit dem Kupplungsgehäuse 2 vorzugsweise lösbar verbunden ist.Although not shown in the drawings, it is conceivable in a modification that the carrier 16 is not on the top the coupling housing 2, but laterally of the coupling housing 2 with the coupling housing 2 is preferably releasably connected.

Auch kommen andere Konstruktionen zur Justierung der Zugöse 14 in Frage. Beispielsweise ist es denkbar, einen Verschwenkmechanismus vorzusehen, um die Zugöse 14 in Längsrichtung L der Übergangskupplung 1 relativ zu dem Zugbügel 8 zu bewegen.Also, other constructions for adjusting the drawbar eye 14 in question. For example, it is conceivable to provide a pivoting mechanism in order to move the drawbar eye 14 in the longitudinal direction L of the transitional coupling 1 relative to the drawbar 8.
