Description

Die Erfindung bezieht sich auf ein Fahrzeug mit einer Vorrichtung zur gelenkigen Anbindung einer Kupplungsstange an das Fahrzeug, wobei die Vorrichtung umfaßt:
eine vertikal angeordnete Anschlagplatte, die in einem Untergestellbereich des Fahrzeugs an einem Rohbau des Fahrzeugs befestigt oder von einem Rohbauabschnitt gebildet ist, wobei die Kupplungsstange derart gelagert ist, dass horizontale Winkelauslenkungen der Kupplungsstange gegenüber ihrer zentralen Ausgangslage in Längsrichtung des Fahrzeugs zugelassen sind, eine an der Anschlagplatte abgestützte zentrale Druckfederanordnung, die mit der Kupplungsstange derart zusammenwirkt, dass bei einer Winkelauslenkung der Kupplungsstange gegenüber ihrer Ausgangslage eine exzentrisch wirkende Rückstellkraft auf die Kupplungsstange ausübbar ist, und eine Zugfederanordnung vorgesehen ist, die am Rohbau des Fahrzeugs abgestützt und über ein Scharniergelenk mit dem der Anschlagplatte zugeordneten Ende der Kuppelstange verbunden ist.The invention relates to a vehicle with a device for the articulated connection of a coupling rod to the vehicle, the device comprising:
a vertically arranged stop plate, which is fastened in a sub-frame area of the vehicle to a body-in-white of the vehicle or is formed by a body-in-white section, the coupling rod being mounted in such a way that horizontal angular displacements of the coupling rod relative to its central starting position in the longitudinal direction of the vehicle are permitted, one at the Central pressure spring arrangement supported by the stop plate, which cooperates with the coupling rod in such a way that an eccentrically acting restoring force can be exerted on the coupling rod when the coupling rod is deflected angularly relative to its starting position, and a tension spring arrangement is provided which is supported on the bodyshell of the vehicle and via a hinge joint with the Stop plate associated end of the coupling rod is connected.

Ein solches Fahrzeug mit einer Vorrichtung zur gelenkigen Anbindung einer Kuppelstange ist beispielsweise aus der EP 1 413 493 A1 bekannt. Die dort bei einem Schienenfahrzeug eingesetzte Vorrichtung kann als Stabilisierungsgelenk bezeichnet werden. Dieses nutzt gezielt eine Nachgiebigkeit von Federanordnungen aus, die als elastische Gelenke wirken. Dabei ist die Nachgiebigkeit in Längsrichtung des Fahrzeugs gegeben und dient insbesondere zur Stabilisierung eines Zugverbandes, zu dem das Fahrzeug gehört, bei Kollisionen.Such a vehicle with a device for the articulated connection of a coupling rod is for example from the EP 1 413 493 A1 known. The device used there in a rail vehicle can be referred to as a stabilizing joint. This systematically uses the flexibility of spring assemblies that act as elastic joints. The flexibility is given in the longitudinal direction of the vehicle and is used in particular to stabilize a train set to which the vehicle belongs in the event of collisions.

Der Einsatz elastischer Gelenke birgt jedoch den Nachteil in sich, dass mögliche horizontale Schwenkwinkel der Kupplungsstange gegenüber dem Rohbau des Fahrzeugs begrenzt sind.However, the use of elastic joints has the disadvantage that possible horizontal pivoting angles of the coupling rod are limited compared to the body-in-white of the vehicle.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Fahrzeug mit einer Vorrichtung zur gelenkigen Anbindung einer Kupplungsstange an das Fahrzeug derart weiterzuentwickeln, dass größere horizontale Schwenkwinkel realisierbar sind.Proceeding from this, the object of the invention is to provide a vehicle with a device for articulated connection to develop a coupling rod to the vehicle in such a way that larger horizontal swivel angles can be realized.

Diese Aufgabe wird bei dem eingangs genannten Fahrzeug dadurch gelöst, dass das Scharniergelenk einen Zugbügel aufweist, an dem ein Gelenkbolzen des Scharniergelenks fixiert ist, der das der Anschlagplatte zugewandte Ende der Kupplungsstange lagert, wobei der Zugbügel über die Zugfederanordnung mit dem Rohbau des Fahrzeugs verbunden ist.This object is achieved in the vehicle mentioned at the outset in that the hinge joint has a drawbar to which a hinge pin of the hinge joint is fixed, which supports the end of the coupling rod facing the stop plate, the drawbar being connected to the bodyshell of the vehicle via the tension spring arrangement ,

Durch den Einsatz des Scharniergelenks ist es möglich, auch für größere horizontale Schwenkwinkel der Kupplungsstange definiert über die Druckfederanordnung eine Rückstellkraft auf die Kupplungsstange auszuüben. Eine Abfederung der Kupplungsstange gegenüber in Längsrichtung des Fahrzeugs wirkenden Druckkräften geschieht über die zentrale Druckfederanordnung. Das Scharniergelenk weist einen Zugbügel aufweisen, an dem ein Gelenkbolzen des Scharniergelenks fixiert ist, der das der Anschlagplatte zugewandte Ende der Kupplungsstange lagert, wobei der Zugbügel über die Zugfederanordnung mit dem Rohbau des Fahrzeugs verbunden ist. Diese Maßnahme gestattet es, eine vertikale Drehachse für das Scharniergelenk und damit eine Schwenkachse für die Kupplungsstange festzulegen, und zwar durch den Gelenkbolzen.By using the hinge joint, it is possible to exert a restoring force on the coupling rod in a defined manner via the compression spring arrangement even for larger horizontal pivoting angles of the coupling rod. A cushioning of the coupling rod against compressive forces acting in the longitudinal direction of the vehicle takes place via the central compression spring arrangement. The hinge joint has a drawbar on which a hinge pin of the hinge joint is fixed, which supports the end of the coupling rod facing the stop plate, the drawbar being connected to the bodyshell of the vehicle via the tension spring arrangement. This measure allows a vertical axis of rotation for the hinge joint and thus a pivot axis for the coupling rod to be determined, specifically by the hinge pin.

Die Zugfederanordnung kann wenigstens zwei Zugfedern umfassen, die vozugsweise horizontal symmetrisch zu der Kupplungsstange angeordnet sind. Dadurch ergibt sich eine geeignete Zugfederung für die Kuppelstange.The tension spring arrangement can comprise at least two tension springs, which are preferably arranged horizontally symmetrically to the coupling rod. This results in a suitable tension spring for the coupling rod.

Der Zugbügel kann eine vertikal wirkende Lagerung für das der Anschlagplatte zugewandte Ende der Kupplungsstange bilden. Dies schafft die gewünschten Bewegungsfreiheitsgrade für die Bewegung der Kupplungsstange und ermöglicht vorzugsweise rein horizontale Schewnkbewegungen.The tension bracket can form a vertically acting bearing for the end of the coupling rod facing the stop plate. This creates the desired degrees of freedom of movement for the movement of the coupling rod and preferably enables purely horizontal pivoting movements.

Die Vorrichtung zur gelenkigen Anbindung einer Kupplungsstange kann einen Berührkörper aufweisen, der zwischen dem der Anschlagplatte zugewandten Ende der Kupplungsstange und der zentralen Druckfcderanordnung angeordnet ist und mit einem Berührabschnitt der Anschlagplatte derart zusammenwirkt, dass bei einer Winkelauslenkung der Kupplungsstange gegenüber ihrer Ausgangslage eine exzentrisch wirkende Rückstellkraft auf die Kupplungsstange ausübbar ist. Bei dieser Ausführungsform erfährt die Kupplungsstange sowohl durch die zentrale Druckfederanordnung als auch über der Berührkörper exzentrisch wirkende Rückstellkräfte.The device for the articulated connection of a coupling rod can have a contact body which is arranged between the end of the coupling rod facing the stop plate and the central pressure arrangement and which interacts with a contact section of the stop plate in such a way that with an angular deflection of the coupling rod relative to its starting position, an eccentrically acting restoring force can be exerted on the coupling rod. In this embodiment, the coupling rod experiences eccentrically acting restoring forces both through the central compression spring arrangement and via the contact body.

Alternativ ist es auch möglich, dass das der Anschlagplatte zugewandte Ende der Kupplungsstange unmittelbar an der zentralen Druckfederanordnung anliegt. Auch kann der Berührkörper fest mit dem Ende der Kupplungsstange verbunden sein. In diesem Fall müßte die Druckfederanordnung allerdings sämtlichen Winkelbewegungen der Kupplungsstange folgen. Bevorzugt besitzt daher der Berührkörper lediglich Berührflächen zur Stirnseite der Kupplungsstange.Alternatively, it is also possible for the end of the coupling rod facing the stop plate to bear directly against the central compression spring arrangement. The contact body can also be firmly connected to the end of the coupling rod. In this case, however, the compression spring arrangement would have to follow all the angular movements of the coupling rod. The contact body therefore preferably has only contact surfaces to the end face of the coupling rod.

Der Gelenkbolzen verläuft bevorzugt durch eine vertikal verlaufende Durchgangsbohrung des Berührkörpers hindurch. In dieser Weise kann Bauraumkonflikten zwischen dem Scharniergelenk und dem Berührkörper begegnet werden.The hinge pin preferably runs through a vertical through bore of the contact body. In this way, space conflicts between the hinge joint and the contact body can be countered.

Die vertikal verlaufende Durchgangsbohrung des Berührkörpers ist vorzugsweise derart bemessen ist, dass der Gelenkbolzen horizontales Spiel hat.The vertical through bore of the contact body is preferably dimensioned such that the hinge pin has horizontal play.

Der Berührkörper kann zwischen einem oberen und einem unteren horizontalen Abschnitt des Zugbügels in das der Anschlagplatte zugewandte Ende der Kuppelstange gesetzt sein. Dadurch ergibt sich eine kompakte Bauweise im Bereich des Scharniergelenks.The contact body can be placed between an upper and a lower horizontal section of the pull bracket in the end of the coupling rod facing the stop plate. This results in a compact design in the area of the hinge joint.

Die Figuren 1 bis 4 zeigen sämtlich Ansichten einer Vorrichtung zur gelenkigen Anbindung einer Kupplungsstange 1 an einen Rohbau eines Fahrzeugs, insbesondere Schienenfahrzeugs. Dabei nimmt die Kupplungsstange 1 eine Ausgangsposition ein, bei der sie weder Zug- noch Druckkräften in Längsrichtung des Fahrzeugs (der Kupplungsstange 1) ausgesetzt ist. Die Kupplungsstange 1 ist letztlich an einer Anschlagplatte 2 des Fahrzeugrohbaus abgestützt. Dabei kann die Anschlagplatte 2 von einem plattenförmigen Abschnitt des Rohbaus selbst gebildet sein. Alternativ ist die Anschlagplatte 2 als Flansch ausgebildet, der mit dem Rohbau des Fahrzeugs beispielsweise verschraubt ist. Seitlich der Kupplungsstange 1 gehen von der Anschlagplatte 2 zwei symmetrisch angeordnete Zugstangen 3 aus, die entweder (Figur 3) über die Anschlagplatte 2 mit dem Rohbau verschraubt sind oder (Figur 6) durch den Rohbau hindurch reichen und an einer rückwertigen Anlagefläche 4 angreifen.The Figures 1 to 4 all show views of a device for the articulated connection of a coupling rod 1 to a body-in-white of a vehicle, in particular a rail vehicle. The coupling rod 1 assumes a starting position in which it is not subjected to tensile or compressive forces in the longitudinal direction of the vehicle (the coupling rod 1). The coupling rod 1 is ultimately supported on a stop plate 2 of the vehicle body shell. The stop plate 2 can be formed by a plate-shaped section of the shell itself. Alternatively, the stop plate 2 is designed as a flange, which is screwed to the bodyshell of the vehicle, for example. To the side of the coupling rod 1, two stop rods 3, symmetrically arranged, extend from the stop plate 2, which either ( Figure 3 ) are screwed to the shell via the stop plate 2 or ( Figure 6 ) reach through the shell and attack on a backward contact surface 4.

Ein horizontal angeordneter Zugbügel 5 ist im Bereich des der Anschlagplatte 2 zugewandten Endes der Kupplungsstange 1 angeordnet und weist einen oberen flachen Abschnitt 6 und einen unteren flachen Abschnitt 7 auf, die beide ebenfalls horizontal verlaufen.A horizontally arranged drawbar 5 is arranged in the region of the end of the coupling rod 1 facing the stop plate 2 and has an upper flat section 6 and a lower flat section 7, both of which likewise run horizontally.

Die Zugstangen 3 sind jeweils auf einer Seite der Kupplungsstange 1 in einem Abstand zu ihr angeordnet. Die seitlichen Enden des Zugbügels 5 sind auf einen Innenabschnitt 8 der jeweiligen Zugstange 3 aufgesteckt und über jeweilige Federelemente 9 gegenüber auf die Kupplungsstange 1 wirkenden Längszugkräften elastisch gelagert.The tie rods 3 are each arranged on one side of the coupling rod 1 at a distance from it. The lateral ends of the pull bracket 5 are plugged onto an inner section 8 of the respective pull rod 3 and are elastically supported via respective spring elements 9 against longitudinal tensile forces acting on the coupling rod 1.

Wie Figur 2 zu entnehmen ist, schließt sich in der dargestellten Ausgangsposition der Kupplungsstange 1 an ihrem der Anschlagplatte 2 zugewandten Ende ein Berührkörper 10 an, der mit stirnseitigen, exzentrisch liegenden Berührflächen 11 der Kupplungsstange 1 zusammenwirkt. Der Berührkörper 10 liegt auf einer der Anschlagplatte 2 zugeordneten Seite an einer zentral angeordneten Druckfederanordnung 12 an, die im dargestellten Ausführungsbeispiel von einem einzelnen Federelement gebildet ist. Das ringförmige Federelement ist dazu geeignet, bei einer Winkelauslenkung der Kupplungsstange 1 und damit einhergehenden Auslenkung des Berührkörpers 10 auf letzteren eine Rückstellkraft auszuüben, die auf die Kupplungsstange 1 übertragen wird und dafür sorgt, dass sie in ihre Ausgangsposition zurückgedrückt wird.How Figure 2 can be seen, in the illustrated starting position of the coupling rod 1, at its end facing the stop plate 2, there is a contact body 10 which interacts with front-side, eccentrically located contact surfaces 11 of the coupling rod 1. The contact body 10 bears on a side assigned to the stop plate 2 against a centrally arranged compression spring arrangement 12, which in the exemplary embodiment shown is formed by a single spring element. The annular spring element is suitable for exerting a restoring force on the latter when there is an angular deflection of the coupling rod 1 and the associated deflection of the contact body 10, which is transmitted to the coupling rod 1 and ensures that it is pushed back into its starting position.

Der Berührkörper 10 ist zwischen dem oberen 6 und dem unteren horizontalen Abschnitt 7 des Zugbügels 5 in das der Anschlagplatte 2 zugewandte Ende der Kupplungsstange 1 gesetzt. Diese zeigt an diesem Ende einen Aufnahmeraum für den Berührkörper 10.The contact body 10 is placed between the upper 6 and the lower horizontal section 7 of the pull bracket 5 in the end of the coupling rod 1 facing the stop plate 2. At this end, this shows a receiving space for the contact body 10.

Der Zugbügel 5 ist Teil eines Scharniergelenks 13, mit dem horizontale Winkelbewegungen der Kupplungsstange 1 zugelassen werden. Dabei wird eine Achse des Scharniergelenks 13 durch einen Gelenkbolzen 14 festgelegt, dessen oberes und unteres Ende jeweils an dem zugeordneten oberen 6 oder unteren Abschnitt 7 des Zugbügels 5 befestigt ist. Der Gelenkbolzen 14 lagert das der Anschlagplatte 2 zugewandte Ende der Kupplungsstange 1.The tension bracket 5 is part of a hinge joint 13 with which horizontal angular movements of the coupling rod 1 are permitted. Here, an axis of the hinge joint 13 is fixed by a hinge pin 14, the upper and lower End is each attached to the associated upper 6 or lower section 7 of the tension bracket 5. The hinge pin 14 supports the end of the coupling rod 1 facing the stop plate 2.

Wie aus Figur 2 hervorgeht, verläuft der Gelenkbolzen 14 durch eine Durchgangsbohrung 15 in dem Berührkörper 10 hindurch. Dabei ist die Durchgangsbohrung 15 horizontal so bemessen, dass der Gelenkbolzen 14 in der horizontalen Querschnittsebene der Durchgangsbohrung 15 mit Spiel gelagert ist.
Aus Figur 5 geht nunmehr die Position der beteiligten Komponenten für den Fall hervor, dass die Kupplungsstange 1 aufgrund einer einwirkenden Längsdruckkraft eine horizontale Winkelauslenkung erfahren hat. Dann löst sich der in Figur 5 untere, hintere Abschnitt des Berührkörpers 10 von seiner zugeordneten Berührfläche 11 an der Kupplungsstange 1, so dass an dieser Stelle keine Kraftübertragung zwischen dem Berührkörper 10 und der Kupplungsstange 1 stattfindet. Auf der gegenüberliegenden Seite, d. h. in Figur 5 der obere Bereich des Berührkörpers 10, liegt der exzentrisch gelegene Abschnitt des Berührkörpers 10 unmittelbar zur Kraftübertragung an seiner zugeordneten Berührfläche 11 an der Kupplungsstange 1 an. Da die Kupplungsstange 1 eine Längsdruckkraft erfahren hat, ist sie gemeinsam mit dem Berührkörper 10 in Richtung der Anschlagplatte 2 gedrückt worden Wie ebenfalls in Figur 5 zu sehen ist, schlägt der der Anschlagplatte 2 zugewandte Rand des Berührkörpers 10 an einem Berührabschnitt 16 der Anschlagplatte 2 an, wobei die Druckfederanordnung 12 komprimiert wird. Durch den ebenfalls exzentrischen Anschlag des Berührkörpers 10 an der Anschlagplatte 2 wird über den Berührkörper 10 eine Rückstellkraft auf die Kupplungsstange 1 übertragen, welche sie in Richtung ihrer Ausgangsposition bewegt.How from Figure 2 emerges, the hinge pin 14 extends through a through hole 15 in the contact body 10. The through hole 15 is dimensioned horizontally so that the hinge pin 14 is mounted with play in the horizontal cross-sectional plane of the through hole 15.
Out Figure 5 the position of the components involved can now be seen in the event that the coupling rod 1 has undergone a horizontal angular deflection due to an acting longitudinal compressive force. Then it dissolves into Figure 5 lower, rear section of the contact body 10 from its associated contact surface 11 on the coupling rod 1, so that no force transmission takes place between the contact body 10 and the coupling rod 1 at this point. On the opposite side, ie in Figure 5 the upper region of the contact body 10, the eccentrically located section of the contact body 10 lies directly against the associated contact surface 11 on the coupling rod 1 for power transmission. Since the coupling rod 1 has experienced a longitudinal compressive force, it has been pressed together with the contact body 10 in the direction of the stop plate 2 Figure 5 can be seen, the edge of the contact body 10 facing the stop plate 2 strikes against a contact section 16 of the stop plate 2, the compression spring arrangement 12 being compressed. Due to the likewise eccentric stop of the contact body 10 on the stop plate 2, a restoring force is transmitted via the contact body 10 to the coupling rod 1, which moves it in the direction of its starting position.
