Description

Die Erfindung betrifft eine Anlenkungseinrichtung für eine Kupplung nach dem Oberbegriff des Anspruchs 1.The invention relates to a coupling device for a clutch according to the preamble of claim 1.

Eine Anlenkungseinrichtung dieser Art ist in der EP 2 322 403 B1 geoffenbart, bei welcher die Federelemente starr eingespannt sind und infolgedessen nicht die Lenkbewegungen der Zugstange mitmachen können. Dadurch wird die Dämpfungswirkung der Federelemente beeinträchtigt, weil die Kupplung sie in ausgelenkter Stellung nur ungleichmässig beansprucht.An articulation device of this type is in the EP 2 322 403 B1 disclosed in which the spring elements are rigidly clamped and consequently can not join the steering movements of the drawbar. As a result, the damping effect of the spring elements is impaired, because the clutch takes her unevenly in deflected position.

Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden und eine Anlenkungseinrichtung der eingangs genannten Art zu schaffen, die auch bei ausgelenkter Kupplung eine optimale Dämpfungswirkung der Federelemente mit möglichst einfachen Mitteln sicherstellt.The invention has for its object to avoid this disadvantage and to provide a linkage device of the type mentioned, which ensures optimal deflection effect of the spring elements with the simplest possible means even with deflected coupling.

Diese Aufgabe ist erfindungsgemäss dadurch gelöst, dass die Zugstange für ein Auslenken zumindest in einer horizontalen Ebene in einer im Gehäuse drehbaren Platte gelagert ist, welche zwischen den Federelementen angeordnet ist.This object is inventively achieved in that the pull rod is mounted for deflecting at least in a horizontal plane in a rotatable plate in the housing, which is arranged between the spring elements.

Damit wird erreicht, dass durch diese Einrichtung eine Auslenkung des mit ihr verbundenen Kupplungskopfes ermöglicht wird und dabei die Zugstange und die auf ihr gelagerten Federelemente und diese Platte ebenfalls diese Schwenkpositionen einnehmen.This ensures that a deflection of the coupling head connected to it is made possible by this device and thereby take the pull rod and mounted on her spring elements and this plate also these pivotal positions.

Es ist im Sinne einer einfachen Konstruktion besonders vorteilhaft, wenn die drehbare Platte und der Lenkbolzen in einer Ringscheibe mit zwei diametral angeordneten Drehzapfen integriert sind, wobei die Ringscheibe mit einer mittigen Durchgangsbohrung für die Zugstange versehen ist.It is particularly advantageous in terms of a simple construction, when the rotatable plate and the steering pin are integrated in an annular disc with two diametrically arranged pivot, said annular disc is provided with a central through hole for the tie rod.

Damit die Federelemente auch eine Auslenkung der Kupplung in der vertikalen Ebene vollziehen können, sieht die Erfindung vor, die Durchgangsbohrung beidseitig sich nach aussen hin aufweitend auszubilden.Thus, the spring elements can also perform a deflection of the coupling in the vertical plane, the invention provides, the through hole bilaterally on both sides expand outwardly form.

Die Erfindung sieht weiterhin vor, dass die Federelemente zum Dämpfen der Druckkräfte auf der dem Kupplungskopf zugewandten Seite der drehbaren Platte angeordnet sind, während die Federelemente zum Dämpfen der Zugkräfte auf der von Kupplungskopf abgewandten Seite der drehbaren Platte montiert sind. Dadurch ist die drehbare Platte in beiden Kraftrichtungen wirksam.The invention further provides that the spring elements are arranged for damping the pressure forces on the coupling head facing side of the rotatable plate, while the spring elements for damping the tensile forces on the side remote from the coupling head the rotatable plate are mounted. As a result, the rotatable plate is effective in both directions of force.

Die in der Kupplung auftretenden Druckkräfte sind in der Praxis ein Vielfaches von den auf sie wirkenden Zugkräften. Die Erfindung sieht daher ebenfalls vor, die Anzahl Federelemente entsprechend den jeweils zu erwartenden Druck- bzw. Zugkräften festzulegen.The pressure forces occurring in the coupling are in practice a multiple of the tensile forces acting on them. The invention therefore also provides for the number of spring elements to be determined in accordance with the respectively expected pressure or tensile forces.

Es ist für eine möglichst gleichmässige Dämpfungswirkung zweckmässig, die Federelemente als Ringscheiben aus einem elastomeren Material herzustellen, die seitlich gegen dazwischenliegende Distanzscheiben aus Blech abgestützt sind.It is expedient for the most even damping effect to produce the spring elements as washers of an elastomeric material, which are laterally supported against intermediate spacers made of sheet metal.

Es ist auch im Sinne einer einfachen, kompakten Bauweise vorteilhaft, wenn die Federelemente auf der Zugstange zwischen einer am vorderen Zugstangenende angeordneten Muffe für den Kupplungskopf und einer am hinteren Zugstangenende angeordneten Arretierscheibe zum Fixieren der Federelemente gegen die drehbare Platte montiert sind.It is also advantageous in terms of a simple, compact design, when the spring elements are mounted on the tie rod between a arranged at the front Zugstangenende sleeve for the coupling head and a rear Zugstangenende arranged locking disc for fixing the spring elements against the rotatable plate.

Zum Erleichtern der Montage sieht die Erfindung auch vor, dass die Arretierscheibe gegen die Federelemente mit einer am hinteren Zugstangenende angeordneten Verschraubung andrückbar ist.To facilitate assembly, the invention also provides that the locking disc can be pressed against the spring elements with a screw arranged on the rear tie rod end.

Die Erfindung sieht ausserdem vor, dass der Lenkbolzen mit der drehbaren Platte in einem hülsenförmigen Gehäuse mit einem am Schienenfahrzeug befestigbaren Flansch gelagert ist. Auf diese Weise kann das Gehäuse mit dem Lenkbolzen, der drehbaren Platte und der Zugstange mit den Federelementen als vormontierte Baugruppe am Schienenfahrzeug fixiert werden.The invention also provides that the steering pin is mounted with the rotatable plate in a sleeve-shaped housing with a fastened to the rail vehicle flange. In this way, the housing with the steering pin, the rotatable plate and the pull rod with the spring elements can be fixed as a preassembled module on the rail vehicle.

Die erfindungsgemässe Anlenkungseinrichtung kann auch mit einer Überlastsicherung versehen werden. In diesem Fall ist das Gehäuse in dem Flansch verschiebbar, wobei beide Teile im Normalbetrieb gegeneinander mit mindestens einem vorzugsweise bolzenförmigen Überlastelement fixiert sind, während bei einem starken Stoss das Überlastelement durch das Gehäuse abgeschert wird und dieses durch den Flansch zusammen mit der drehbaren Platte und der Zugstange mit den Federelementen nach hinten geschoben wird.The inventive articulation device can also be provided with an overload protection. In this case the housing is in displaceable with the flange, wherein both parts are fixed against each other in normal operation with at least one preferably bolt-shaped overload element, while at a strong shock, the overload element is sheared by the housing and this pushed through the flange together with the rotatable plate and the tie rod with the spring elements to the rear becomes.

Das Gehäuse kann auch am vom Kupplungskopf abgekehrten Ende mit einem am Flansch befestigten Sicherheitsorgan in der Gestalt eines plastisch verformbaren Rohrstücks versehen sein, das bei Überlast energieabsorbierend mit einer in das Rohrstück eindringenden Nabe des Gehäuses zusammenwirkt.The housing may also be provided on the end facing away from the coupling head with a safety element attached to the flange in the form of a plastically deformable piece of pipe which interacts with overload in an energy absorbing manner with a penetrating into the pipe hub of the housing.

Die Erfindung ist nachfolgend anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnung näher erläutert. Es zeigen:

The invention is explained in more detail by means of embodiments with reference to the drawings. Show it:

Die in Fig.1 gezeigte Anlenkungseinrichtung ist als unabhängige Baugruppe konstruiert und sie umfasst eine Zugstange 1 mit auf ihr gelagerten Federelementen 2a, 2b zum Dämpfen der auf die Kupplung wirkenden Druck- und Zugkräfte, sowie ein Gehäuse 3 mit einem Flansch 4, mit dem die Baugruppe an das Schienenfahrzeug oder ähnlichem montiert wird.In the Fig.1 The articulation device shown is constructed as an independent module and it comprises a tie rod 1 with spring elements 2a, 2b mounted thereon for damping the compressive and tensile forces acting on the coupling, and a housing 3 with a flange 4, with which the assembly to the rail vehicle or similar is mounted.

Erfindungsgemäss sind die Federelemente 2a, 2b beidseitig einer Platte 5 angeordnet, die um die Drehachse 6 eines Lenkbolzens 7 für die Zugstange 1 drehbar ist. Wie aus Fig. 2 ersichtlich, umfasst die drehbare Platte 5 eine Ringscheibe 8 und einen Lenkbolzen 7 mit zwei diametral angeordneten Drehzapfen 9a, 9b, wobei die Ringscheibe 8 mit einer mittigen Durchgangsbohrung 10 versehen ist, durch welche die Zugstange 1 ragt, während die Drehzapfen 9a. 9b in Bohrungen des Gehäuses 3 gelagert sind. Zur Ermöglichung des Zusammenbaus ist das Gehäuse 3 entlang der mittleren Diametralebene durch zwei Halbschalen gebildet.According to the invention, the spring elements 2a, 2b are arranged on both sides of a plate 5 which is rotatable about the axis of rotation 6 of a steering pin 7 for the pull rod 1. How out Fig. 2 As can be seen, the rotatable plate 5 comprises an annular disc 8 and a steering pin 7 with two diametrically arranged pivot pins 9a, 9b, the annular disc 8 being provided with a central throughbore 10 through which the tie rod 1 projects, while the pivot pins 9a. 9b are mounted in bores of the housing 3. To facilitate assembly, the housing 3 is formed along the central diametrical plane by two half-shells.

Die Durchgangsbohrung 10 sowie die Zugstange 1 sind vorteilhaft im Querschnitt gesehen beidseitig je mit einer Abflachung 10' versehen, damit die Zugstange 1 darin drehgesichert ist. Zudem ist diese Durchgangsbohrung 10 zumindest im oberen und unteren Bereich in Achsrichtung gesehen ausgehend von ihrer Mitte beidseitig nach aussen hin mit Aufweitungen 10" ausgebildet. Dadurch wird auch eine Auslenkung der Kupplung in vertikaler Ebene ermöglicht, wobei die Bohrung so ausgelegt ist, dass die Kupplung in der vertikalen Ebene eine Auslenkung von ca. +/- 6° nach oben und unten ausführen kann.The through hole 10 and the pull rod 1 are advantageous seen in cross section on both sides each provided with a flattening 10 ', so that the pull rod 1 is secured against rotation therein. In addition, this through-hole 10, viewed at least in the upper and lower regions in the axial direction, is formed on both sides outward from its center with widenings 10 ", thereby permitting a deflection of the coupling in a vertical plane, wherein the bore is designed such that the coupling in the vertical plane can perform a deflection of about +/- 6 ° up and down.

Die Konstruktion ist für eine Auslenkung der Zugstange 1 und damit des Kupplungskopfes in der horizontalen Ebene von ca. +/- 20° nach rechts und links ausgelegt.The design is designed for a deflection of the tie rod 1 and thus the coupling head in the horizontal plane of about +/- 20 ° to the right and left.

Die Federelemente 2a auf der dem Kupplungskopf zugewandten Seite der drehbaren Platte 5 dienen zum Dämpfen der auf die Kupplung wirkenden Druckkräfte. Sie sind aus einem elastomeren Material hergestellt, wobei das Federpaket mit einem max. Druckhub von insgesamt ca. 60 mm ausgelegt ist. Das Federelement 2b auf der vom Kupplungskopf abgewandten Seite der drehbaren Platte 5 ist ebenfalls aus einem elastomeren Material hergestellt und dient seinerseits zum Dämpfen der auf die Kupplung wirkenden Zugkräfte. Diese sind wesentlich kleiner als die auftretenden Druckkräfte. Demgemäss ist das Federelement 2b mit einem max. Zughub von ca. 10 mm ausgelegt.The spring elements 2a on the side facing the coupling head of the rotatable plate 5 serve to damp the compressive forces acting on the coupling. They are made of an elastomeric material, the spring package with a max. Pressure stroke of a total of about 60 mm is designed. The spring element 2b on the side facing away from the coupling head side of the rotatable plate 5 is also made of an elastomeric material and in turn serves to damp the tensile forces acting on the coupling. These are much smaller than the pressure forces occurring. Accordingly, the spring element 2b with a max. Extension stroke of approx. 10 mm.

Die Anzahl Federelemente vorder- und rückseitig der drehbaren Platte 5 kann von Fall zu Fall den beim Kuppeln zu erwartenden Druck- und Zugkräften festgelegt werden. Bei dem gebildeten Paket gemäss Fig. 1 sind zwischen der vorderen Muffe und der Platte fünf Federelemente 2a bzw. dieses eine Federelement 2b zwischen der Platte und einer rückseitigen Arretierscheibe 13 vorgesehen.The number of spring elements front and back of the rotatable plate 5 can be determined from case to case the expected during coupling pressure and tensile forces. In the package formed according Fig. 1 are provided between the front sleeve and the plate five spring elements 2a and this one spring element 2b between the plate and a rear-side locking disc 13.

Bei einer Auslenkung der Kupplung wird die drehbare Platte 5 innerhalb der obengenannten Grenzwerte mitausgelenkt. Das hat zur Folge, dass auch bei ausgelenkter Kupplung die auf sie wirkenden Druck- und Zugkräfte die Federelement 2a, 2b auf ihrer Gesamtfläche gleichmässig beaufschlagen. Dadurch ist die Dämpfungswirkung der Federelemente optimal. In diesem Sinne ist es vorteilhaft, wenn die Federelemente seitlich mit dazwischenliegenden Distanzscheiben 11 aus Blech abgestützt sind.With a deflection of the coupling, the rotatable plate 5 is deflected within the above limits. As a result, even when the coupling is deflected, the compressive and tensile forces acting on it act uniformly on the spring elements 2a, 2b over their entire area. As a result, the damping effect of the spring elements is optimal. In this sense, it is advantageous if the spring elements are supported laterally with intermediate spacers 11 made of sheet metal.

Die Federelemente 2a, 2b sind auf der Zugstange 1 zwischen einer am vorderen Zugstangenende angeordneten Muffe 12, an welchem der Kupplungskopf beispielsweise durch Schweissen verbunden werden kann, und der am hinteren Zugstangenende angeordneten Arretierscheibe 13 eingebaut. Letztere dient zum Fixieren der Federelemente 2a, 2b und der drehbaren Platte 5 gegen die Muffe 12, indem sie gegen mit einer am hinteren Zugstangenende einschraubbaren Verschraubung 14 angedrückt wird.The spring elements 2a, 2b are mounted on the tie rod 1 between a arranged on the front Zugstangenende sleeve 12, to which the coupling head can be connected, for example by welding, and the rear Zugstangenende arranged locking disc 13. The latter is used to fix the spring elements 2a, 2b and the rotatable plate 5 against the sleeve 12 by being pressed against a screwed with the rear tie rod fitting 14.

Nachdem die Baugruppe bestehend aus dem Gehäuse 3 mit dem Flansch 4, der drehbaren Platte 5 mit dem Lenkbolzen 7 und der Zugstange 1 mit den Federelementen 2a, 2b an das Schienenfahrzeug montiert ist, kann die Kupplung mit Kupplungskopf und Zug- und Stossvorrichtung mit der Muffe 12 der Zugstange 1 verschweisst werden. Die beschriebene Bauweise ist sowohl für den Zusammenbau der Anlenkungseinrichtung als auch für die Inspektion und Einstellbarkeit der einzelnen Bauteile vorteilhaft.After the assembly consisting of the housing 3 with the flange 4, the rotatable plate 5 with the steering pin 7 and the tie rod 1 with the spring elements 2a, 2b is mounted on the rail vehicle, the coupling with coupling head and pulling and pushing device with the sleeve 12 of the tie rod 1 are welded. The described Construction is advantageous both for the assembly of the articulation device as well as for the inspection and adjustability of the individual components.

Die Anlenkungseinrichtung kann auch mit einer Überlastsicherung versehen sein. In diesem Fall ist das Gehäuse 3 axial in dem Flansch 4 verschiebbar, wobei beide Teile im Normalbetrieb gegeneinander mit bolzenförmigen Überlastelementen 15a, 15b fixiert sind, die bei Überlast durch das Gehäuse 3 abgeschert werden. Dadurch kann dieses Gehäuse durch den Flansch 4 zusammen mit der drehbaren Platte 5 und der Zugstange 1 mit den Federelementen 2a, 2b nach hinten geschoben werden. Die Anzahl Überlastelemente kann je nach einer definierten Aufprallkraft variieren.The articulation device can also be provided with an overload protection. In this case, the housing 3 is axially displaceable in the flange 4, wherein both parts are fixed in normal operation against each other with bolt-shaped overload elements 15 a, 15 b, which are sheared off in case of overload by the housing 3. Thereby, this housing can be pushed by the flange 4 together with the rotatable plate 5 and the tie rod 1 with the spring elements 2a, 2b to the rear. The number of overload elements can vary depending on a defined impact force.

Die Anlenkungseinrichtung kann im Rahmen der Erfindung auch eine Sicherheitsvorrichtung beinhalten, die etwa beim Aufprall eines anderen Fahrzeugs die Aufprallenergie innerhalb bestimmter Grenzen absorbiert. Eine solche Vorrichtung ist in Fig. 3 dargestellt.
