Description

Die Erfindung betrifft eine Eisenbahnwagen - Kuppelstange mit Richtgelenken undThe invention relates to a railway car - coupling rod with straightening joints and

Doppelfedersäulenanordnung für kurz gekuppelte Güterwageneinheiten gemäß dem Oberbegriff des Anspruches 1 oder 2.Double spring column arrangement for short coupled freight car units according to the preamble of claim 1 or 2.

Eisenbahnwagen -Kuppelstangen mit Richtgelenken und Doppelfedersäulenanordnung zum Kuppeln von leichtgewichtigen Güterwagen zu mehrgliedrigen Einheiten sind bereits bekannt.Railcar couplers with straightening joints and double spring column assembly for coupling lightweight freight cars to multi-unit units are already known.

In der DE 102 47 621 wurde bereits eine Lösung vorgeschlagen, bei der zwischen den Richtgelenkplatten, welche an jedem Ende des Kuppelstangenrohres angeordnet sind, und den Stützlagerplatten Doppelfedersäulen mit einem Abstand "a" angeordnet sind.In the DE 102 47 621 has already been proposed a solution in which between the directional hinge plates, which are arranged at each end of the coupling rod tube, and the support bearing plates Doppelfedersäulen with a distance "a" are arranged.

In den Stützlagerplatten ist die Kuppelstange über die Kuppelstangenendteile gelenkig gelagert, wobei die Stützlagerplatten mit den Kupplungsträgem des Untergestelles verbunden sind. Über mindestens zwei Kuppelstangenendteile je Ende ist die Kuppelstange druckseitig, elastisch und spielfrei mit dem Untergestell verspannt. Entsprechend den vorgeschlagenen Bauarten werden bis zu 3 Kuppelstangenendteile verwendet. Durch den relativ großen Abstand der Federscheiben werden beim Kuppelstangenausschlag bedeutende Richtgelenkwirkungen erzielt.In the support bearing plates, the coupling rod is articulated via the Kuppelstangenendteile, wherein the support bearing plates are connected to the Kupplungssträgem of the undercarriage. About at least two Kuppelstangenendteile each end of the coupling rod is pressure side, elastic and backlash braced with the base. According to the proposed designs up to 3 coupling rod end parts are used. Due to the relatively large distance of the spring washers Kuppelstangenausschlag significant directional joint effects are achieved.

Vorteilhaft wirkt sich das aus bei langen Kuppelstangen mit relativ geringem Ausschlagwinkel in horizontaler Richtung. Die relativ feste Verspannung der Wagen wirkt sich auch positiv auf das Laufgüteverhalten aus.This has an advantageous effect in the case of long coupling rods with a relatively small deflection angle in the horizontal direction. The relatively tight tension of the car also has a positive effect on the run quality behavior.

Kurze Kuppelstangen verursachen dagegen, zum Beispiel bei Spießgangstellungen, größere Ausschlagwinkel. Wenn man dafür eine kontinuierliche begrenzte Zunahme der Richtgelenkwirkung anstrebt, sind Federpaare mit großer Elastizität und damit grossen Federwegen nötig. Das bedeutet eine druckseitige Anordnung einer großen Anzahl von Federscheiben.On the other hand, short coupling rods cause larger deflection angles, for example in the case of skewer passages. If one strives for a continuous limited increase in the directional joint effect, spring pairs are required with great elasticity and thus large spring travel. This means a pressure-side arrangement of a large number of spring washers.

Diese Ausführung ist platzaufwendig und verursacht hohe Kosten im Neubau und in der Unterhaltung. Verwendet man hingegen druckseitig nur ein bis zwei Federscheiben, so kann es bei großen Ausschlagwinkeln kurzzeitig zu unzulässigen Rückstellkräften kommen.This design is space consuming and causes high costs in new construction and in entertainment. If, on the other hand, only one or two spring washers are used on the pressure side, in the case of large deflection angles it can briefly lead to inadmissible restoring forces.

Eine weitere Ausführung eines Richtgelenkes wurde in der DE 103 05 937 vorgeschlagen. Die Anordnung von Federsäulenpaaren mit großen Federabständen bei gleichzeitiger Sicherung einer extremen Längenanpassbarkeit durch ein Nachstecken eines inneren Teleskoprohres, entspricht der erstgenannten Ausführung mit den genannten Vor- und Nachteilen.Another embodiment of a directional joint was in the DE 103 05 937 proposed. The arrangement of pairs of spring columns with large spring distances while ensuring extreme length adaptability by plugging an inner Telescopic tube, corresponds to the former design with the above advantages and disadvantages.

In Figur 3 wird noch eine Lösung vorschlagen, die die Anordnung eines zusätzlichen Drehpunktes 11 zwischen Richtgelenkplatte und Kupplungsrohr vorsieht. Diese Lösung sichert jedoch ebenfalls keine kontinuierliche Zunahme der Richtgelenkwirkung über den Ausschlagwinkelbereich. Darüber hinaus ist diese Ausführung mit einem beweglichen Kopf an jedem Ende auch kosten-, unterhaltungs- und gewichtsaufwendig.In FIG. 3 will propose a solution that provides the arrangement of an additional pivot point 11 between the directional joint plate and the coupling tube. However, this solution also does not ensure a continuous increase in the directional articulation effect over the range of deflection angles. In addition, this design with a movable head at each end is also costly, entertaining and weight-consuming.

In der EP 1 342 637 wurde ebenfalls eine Kuppelstange mit einem Hochleistungsrichtgelenk vorgeschlagen. Dabei handelt es um ein Richtgelenk mit einem Endzugstangenteil, welches die Kuppelstangen mit ihren Richtgelenkplatten über Stützlagerplatten mit dem Untergestell verbindet. Durch die Anordnung einer Teleskoprohrverbindung und mehreren Innenfederelementen wird eine stetige elastische Anbindung der Kuppelstange an das Untergestell erreicht. Dabei besitzt die Richtgelenkplatte zur Stützlagerplatte hin eine sphärische Abrollfläche, die bei Kuppelstangenausschlägen eine Verlagerung des Längskraft-Übertragungspunktes nach außen verursacht, wodurch ein Rückstellmoment erzeugt wird.In the EP 1 342 637 A coupling rod with a high-performance articulation was also proposed. It is a directional joint with a Endzugstangenenteil, which connects the coupling rods with their directional joint plates via support bearing plates with the base. The arrangement of a telescopic tube connection and a plurality of inner spring elements a continuous elastic connection of the coupling rod is achieved at the base. In this case, the directional joint plate has a spherical rolling surface towards the support bearing plate, which causes a displacement of the longitudinal force transmission point to the outside in Kuppelstangenausschlägen, creating a restoring moment is generated.

Nachteile dieser Ausführung liegen besonders in hohen Herstellungskosten und einem hohen Gewichtsanteil infolge der komplizierten Teleskoprohrverbindung und darin, dass sehr große Rückstellmomente nicht erzeugt werden können.Disadvantages of this design are particularly high production costs and a high weight fraction due to the complicated telescopic tube connection and that very large restoring moments can not be generated.

Die Aufgabe der Erfindung ist es, eine Eisenbahnwagen - Kuppelstange zu schaffen, welche die Nachteile der bekannten Lösungen vermeidet und durch ein verbessertes Wirkungsprinzip die Richtgelenkparameter und die Längenverstellbarkeit zu optimieren.The object of the invention is to provide a railway car - coupling rod, which avoids the disadvantages of the known solutions and to optimize the directional joint parameters and the length adjustability by an improved mode of action.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 oder 2 gelöst. Vorteilhafte Ergänzungen der Erfindung gehen aus den Unteransprüchen hervor.The object is achieved by the features of claim 1 or 2. Advantageous additions of the invention will become apparent from the dependent claims.

Das Wesentliche der Erfindung ist, dass je zwischen den Kuppelstangenendplatten und den Stützlagerplatten sich eine Richtgelenkschwingplatte befindet, die sich kuppelstangenseitig über ein paralleles Federscheibenpaar abstützend angeordnet ist, und dass die Richtgelenkschwingplatte zur Stützlagerplatte hin zur vertikalen und/oder horizontalen Verlagerung des Längskraftübertragungspunktes der Längsdruckkräfte LDK bei Kuppelstangenausschlägen sphärische Abrollflächen besitzt.The essence of the invention is that each between the coupling rod end plates and the support bearing plates is a directional joint oscillating plate which is arranged Kupuppstangenseitig supporting a parallel pair of spring washers, and that the Richtgelenkschwingplatte to the support bearing plate towards the vertical and / or horizontal displacement of the longitudinal force transmission point of the longitudinal compressive forces L DK has spherical rolling surfaces in Kuppelstangenausschlägen.

Weiterhin ist erfindungsgemäß, dass in Abhängigkeit der Drucksteifigkeit des parallelen Federscheibenpaares und des Erreichens eines definierten Kuppelstangenausschlages und einer definierten Anfangslängsdruckkraft über die Anordnung von Federwegbegrenzern ausschlagseitig ein starrer Kraftfluss unter Ausschaltung des Federscheibenpaares zwischen Richtgelenkschwingplatte und der jeweiligen Kuppelstangenendplatte oder der Stützlagerplatte eintritt, und dass der sich bis dahin eingestellt Ausschlagwinkel der Richtgelenkschwingplatte als Ausschlagkorrekturwinkel αAK über eine gegenläufige Korrektur der sphärischen Abrollflächen der Richtgelenkschwingplatte zur Stützlagerplatte hin ausgeglichen wird.Furthermore, according to the invention, that depending on the compressive stiffness of the parallel pair of spring disk and reaching a defined Kuppelstangenausschlag and a defined initial longitudinal compressive force on the arrangement of Federwegbegrenzern on the outset a rigid power flow under elimination of the washer pair between the directional joint and the respective Kuppelstangenendplatte or the support bearing plate occurs, and that the until then set rash of Richtrichtschwingplatte as Ausschlagkorrekturwinkel α AK over an opposite correction of the spherical rolling surfaces of the directional joint oscillating plate to the support bearing plate out is compensated.

Weitere Merkmale der Erfindung sind, dass zwei parallele paarweise Endzugstangenteile mit Federscheibenpaaren Anwendung finden, und dass die Richtgelenkschwingplatte zwischen den beiden Endzugstangenteilen ihre Führung findet,
und dass die Kuppelstangenendplatten, die Stützlagerplatten und die Richtgelenkschwingplatten Öffnungen besitzen, welche Platz für das Durchschieben eines Innenteleskoprohres zur Kuppelstangenlängennachstellung besitzen,
und dass die Anordnung des druckseitigen parallelen Federscheibenpaares reziprok stützplattenseitig und die der sphärischen Abrollflächen kuppelstangenseitig erfolgt, und dass bei Verwendung von nur einem Endzugstangenteil je Kuppelstangenende die Verbindung mit der Kuppelstange in Abhängigkeit von den Richtgelenkparametem gelenkig oder starr ausgeführt ist,
und dass die Richtgelenkschwingplatten an den Endzugstangenteilen gelenkig und axial verschiebbar gelagert sind.Further features of the invention are that two parallel paired Endzugstangenteile with pairs of spring washers are used, and that the directional joint oscillating plate between the two Endzugstangentilteilen their leadership,
and that the coupling rod end plates, the support bearing plates and the directional joint vibration plates have openings which have room for the passage of an inner telescopic tube for coupling rod length adjustment,
and that the arrangement of the pressure-side parallel spring washer pair reciprocally supporting plate side and the spherical rolling surfaces Kuppelstangenseitig, and that when using only one Endzugstangenenteil per Kuppelstangenende the connection with the coupling rod is articulated or rigid depending on the Richtgelenkparametem,
and that the Richtgelenkschwingplatten are articulated and axially displaceable on the Endzugstangenteilen.

Die vorstehende erfindungsgemäße Lösung stellt einen Beitrag zur Optimierung des Richtgelenkprinzips dar und zwar insofern, dass die Doppelfedersäulenanordnung eine besonders horizontal stabile und umfassende Richtgelenkwirkung ermöglicht, die gepaart mit einer Richtgelenkschwingplatte gleichzeitig auch eine kontinuierlich ansteigende Wirkung über den gesamten Ausschwenkwinkel sicher stellt.The above solution according to the invention is a contribution to the optimization of the directional articulation principle and to the extent that the double spring column arrangement allows a particularly horizontal stable and comprehensive directional joint effect, which also ensures a continuously increasing effect over the entire Ausschwenkwinkel paired with a directional joint oscillating plate.

Gegenüber von im Ergebnis vergleichbaren Lösungen werden Einspaarungen bei den Kosten in der Herstellung, der Unterhaltung bei gleichzeitig niedriger Eigenmasse erzielt.Compared to the result comparable solutions savings in the cost of manufacturing, entertainment are achieved at the same time low net mass.

Die Figuren 2,3 und 4 zeigen Draufsichten auf die erfindungsgemäße Einrichtung. Dabei sind jeweils an den Enden der Kuppelstangen 2 Kuppelstangenendplatten 4 angeordnet. Über die Endzugstangenteile 8 sind die Kuppelstangen 2 gelenkig an den Stützlagerplatten 5 angeschlossen. Die Stützlagerplatten 5 übertragen die Druck- und Zugkräfte aus dem Fahr- und Rangierbetrieb zu den Kupplungsträgern des Untergestelles 1. Zwischen den Kupplungsträgerendplatten 4 und den Stützlagerplatten 5 ist eine Richtgelenkschwingplatte 9 angeordnet mit ihrer sphärischen Abrollfläche 11 in Richtung Stützlagerplatte 5. Zwischen den Kuppelstangenendplatten 4 und der Richtgelenkschwingplatte 9 ist hier ein Federscheibenpaar 6 vorgesehen, welches eine Doppelfedersäulenanordnung darstellt. Die zwischen den Kuppelstangenendplatten 4 und den Stützlagerplatten 5 angeordneten Teile sowie das vor der Stützlagerplatte 5 angeordnet zugseitige Federwerk 7 werden durch ein Endzugstangenteit 8 vorgespannt untereinander verbunden.The Figures 2,3 and 4 show plan views of the inventive device. In each case 2 Kuppelstangenendplatten 4 are arranged at the ends of the coupling rods. About the Endzugstangenteile 8, the coupling rods 2 are pivotally connected to the support bearing plates 5. The support bearing plates 5 transmit the compressive and tensile forces from the driving and maneuvering to the coupling members of the underframe 1. Between the Kupplungssträgerendplatten 4 and the support bearing plates 5 is a Directional joint oscillating plate 9 arranged with its spherical rolling surface 11 in the direction of the support bearing plate 5. Between the coupling rod end plates 4 and the directional joint oscillating plate 9, a spring washer pair 6 is provided here, which represents a double spring column arrangement. The arranged between the coupling rod end plates 4 and the support bearing plates 5 parts and arranged in front of the support bearing plate 5 Zugseitige spring mechanism 7 are biased by a Endzugstangenteit 8 interconnected.

Figur 2 zeigt ein Endzugstangenteil 8, welches biegesteif mit der Kuppelstangenendplatte 4 verbunden ist und am Stützlagerplattenanschluss eine Gelenkverbindung besitzt. In Abhängigkeit der Leistungsparameter des Richtgelenkes ist auch vorgesehen, wie Figur 3 zeigt, das Endzugstangenteil 8 in der Kuppelstangenendplatte gelenkig zu befestigen. Die Druckfedem des Federscheibenpaares 6 sind gemäß den Figuren 1; 2 und 3 über Federscheibenarretierungen 15 gehalten. Die Richtgelenkschwingplatte 9 ist gelenkig und längsverschiebbar mit den Endzugstangenteilen 8 verbunden. Zwischen der Richtgelenkschwingplatte 9 und der Kuppelstangenendplatte 4 sind gemäß den Figuren 1; 2 und 3 Federwegbegrenzer 10 angeordnet, welche einen druckseitigen Federweg Fw zulassen. Bei zentraler gleichmäßiger Belastung der beiden Druckfedem des Federscheibenpaares 6 erfolgt eine ausreichende Federung und Dämpfung der auftretenden Rangierstöße. Wirkt die Längsdruckkraft LDK jedoch im Gleisbogen unter Kuppelstangenausschlägen so wird zunehmend nur jeweils eine Federscheibe belastet und die weit außerhalb angeordneten Federwegbegrenzer 10 kommen infolge des Kippweges der Kuppelstangenendplatte und einer anfänglichen Längsdruckkraft, die nur ein Teil der in kritischen Gleisradien zugelassenen Höhe beträgt, frühzeitig zur Anlage. FIG. 2 shows a Endzugstangenteil 8, which is rigidly connected to the Kuppelstangenendplatte 4 and the support bearing plate connection has a hinge connection. Depending on the performance parameters of the directional joint is also provided as FIG. 3 shows, the Endzugstangenteil 8 hinged in the coupling rod end plate. The compression springs of the spring washer pair 6 are in accordance with Figures 1; 2 and 3 held by spring disk locks 15. The Richtgelenkschwingplatte 9 is hinged and longitudinally displaceable connected to the Endzugstangenteilen 8. Between the directional joint oscillating plate 9 and the coupling rod end plate 4 are in accordance with the Figures 1; 2 and 3 Federwegbegrenzer 10 arranged, which allow a pressure-side spring travel F w . With central uniform loading of the two compression springs of the pair of spring washers 6, there is sufficient suspension and damping of the shunting shocks that occur. However, if the longitudinal compressive force L DK acts in the track arc under Kuppelstangenausschläge so only one spring washer is increasingly loaded and far outwardly arranged Federwegbegrenzer 10 come due to the Kippweges the Kuppelstangenendplatte and an initial longitudinal compressive force, which is only a part of the allowed in critical track radii height, early to Investment.

Der Federweg Fw wird also bestimmt, durch den Kippweg der Kuppelstange 2 bei Kurvenfahrt und unterschiedlichen Wagenhöhen zueinander z.B. unterschiedlichen Beladezuständen und dem anfänglichen Federweg aus einer definierten Längsdruckkraft LDK. Mit den Anschlägen 10 der Federwegbegrenzung an der Kippseite wird eine starre Verbindung in vertikaler und horizontaler Ebene zwischen Richtgelenkschwingplatte 9 und Kuppelstangenendplatte 4 hergestellt. Bis dahin legt die Richtgelenkschwingplatte 9 einen Ausschlagkorrekturwinkel αAK zurück, der durch einen größeren horizontalen Richtgelenkradius RH im Vorlauf der Richtgelenkschwingplatte 9 ausgeglichen, das heißt korrigiert wird.The spring travel F w is thus determined by the tilting of the coupling rod 2 when cornering and different car heights to each other, for example, different loading conditions and the initial spring travel from a defined longitudinal pressure L DK . With the stops 10 of the travel limit on the tilting side a rigid connection in the vertical and horizontal plane between the directional joint oscillating plate 9 and coupling rod end plate 4 is made. Until then sets the directional joint oscillating plate 9 a rash correction angle α AK back, which is compensated by a larger horizontal directional joint radius R H in the flow of the directional joint oscillating plate 9, that is corrected.

Die Richtgelenkschwingplatte 9 besitzt, für eine optimale Verschiebung des Längskraftübertragungspunktes 14, zur jeweiligen Anlageseite hin, eine sphärische Abrolloberfläche mit unterschiedlichen oder gemeinsamen gleichgroßen horizontalen und vertikalen Abrollradien RH und RV, wobei sich bei getrennten Abrollflächen eine derselben auf der Gegenseite befinden kann.The directional joint oscillating plate 9 has, for an optimal displacement of the longitudinal force transmission point 14, to the respective plant side out, a spherical Abrolloberfläche with different or common equal horizontal and vertical rolling radii R H and R V , which may be located on separate separation surfaces one of them on the opposite side.

Gemäß der Figur 4 ist es erfindungsgemäß auch vorgesehen, paarweise Endzugstangenteile 8 zwischen den Kuppelstangenendplatten 4 und den Stützlagerplatten 5 anzuordnen. Die Richtgelenkschwingplatte 9 findet dabei in diesen beiden Endzugstangenendteilen 8 ihre Führung. Die druckseitigen Federscheibenpaare können dabei wahlweise kuppelstangenendplattenseitig oder stützlagerplattenseitig angeordnet sein.According to the FIG. 4 it is also provided according to the invention, to arrange pairwise Endzugstangenteile 8 between the Kuppelstangenendplatten 4 and the support bearing plates 5. The Richtgelenkschwingplatte 9 finds its way in these two Endzugstangenendteilen 8. The pressure-side pairs of spring disks can optionally be arranged duplex end plate side or support bearing plate side.

Der jeweilig gewählten Anordnung Rechnung tragend sind auch die Federwegbegrenzer 10 angeordnet und der Ausschlagkorrekturwinkel αAK ausgeführt.Taking into account the arrangement chosen in each case, the spring travel limiters 10 are also arranged and the deflection correction angle α AK is executed.

Es ist weiter bei der vorstehenden Ausführung vorgesehen, die Kuppelstangenendplatten 4, die Stützlagerplatten 5 und die Richtgelenkschwingplatte 9 mit Öffnungen 12 zu versehen, durch welche ein Innenteleskoprohr zur Längenverstellung der Kuppelstangen hindurch bewegt werden kann. Damit ist eine einfache Lösung des Problems einer extremen Längenverstellbarkeit der Kuppelstange 2 gegeben. Dabei sind die vertikalen und horizontalen Abrollflächen 11 an den Außenbereichen der Richtgelenkschwingplatten vorgesehen, wodurch in den Extremausschlagstellungen der Kuppelstange 2 die notwendige Verlagerung der Druckkraftübertragungspunkte noch gesichert werden kann.It is further provided in the above embodiment, the Kuppelstangenendplatten 4, the support bearing plates 5 and the articulated pivot plate 9 to be provided with openings 12 through which an inner telescopic tube for length adjustment of the coupling rods can be moved therethrough. For a simple solution to the problem of extreme length adjustability of the coupling rod 2 is given. The vertical and horizontal rolling surfaces 11 are provided on the outer regions of the directional joint vibration plates, whereby the necessary displacement of the pressure force transmission points can still be secured in the extreme extension positions of the coupling rod 2.

    in that in each case a directional joint swing plate (9), which is arranged supported on the coupling bar side by means of the parallel spring washer pair (6), is located between the coupling bar end plates (4) and the support bearing plates (5), and in that the directional joint swing plate (9) has, towards the support bearing plate (5), spherical rolling faces (11) for the vertical and/or horizontal movement of the longitudinal force-transmission point (14) of the longitudinal compressive forces (LDK) which occur in the event of deflections of the coupling bars.
  2. Coupling bar for a railway wagon, having directional joints and a double-spring column arrangement for short-coupled goods wagon units, composed of a coupling bar pipe (3) with fixed coupling bar end plates (4) at both ends and support bearing plates (5) on the undercarriage and of the pressure-side spring washer pairs (6) which are arranged between the latter and are arranged clamped to tension-side spring mechanisms (7) via end tension rod parts (8),
    characterized
    in that in each case a directional joint swing plate (9), which is arranged supported on the support bearing plate side by means of the parallel spring washer pair (6), is located between the coupling bar end plates (4) and the support bearing plates (5), and in that the directional joint swing plate (9) has, towards the coupling bar end plate (4), spherical rolling faces (11) for the vertical and/or horizontal movement of the longitudinal force-transmission point (14) of the longitudinal compressive forces (LDK) which occur in the event of deflections of the coupling bar.
  3. Coupling bar for a railway wagon according to Claim 1 or 2,
    characterized
    in that, depending on the compressive rigidity of the parallel spring washer pair (6) and the implementation of a defined coupling bar deflection and a defined initial longitudinal compressive force (LDK) via the arrangement of spring travel limiters (10), a rigid frictional engagement occurs on the deflection side with the exclusion of the spring washer pair (6) between the directional joint swing plate (9) and the respective coupling bar end plate (4) or the support bearing plate (5), and in that the deflection angle of the directional joint swing plate (9) which has occurred until then is compensated as a deflection correction angle (αAK) by oppositely directed correction of the spherical rolling faces (11) of the directional joint swing plates (9) towards the support bearing plate (5) or coupling bar end plate (4).
  4. Coupling bar for a railway wagon according to at least one of the preceding claims,
    characterized
    in that two parallel paired end tension rod parts (8) with spring washer pairs (6) are employed, and in that the directional joint swing plate (9) is guided between the two end tension rod parts (8).
  5. Coupling bar for a railway wagon according to Claim 4, characterized
    in that the coupling bar end plates (4), the support bearing plates (5) and the directional joint swing plate (9) have openings (12) which have space for a telescopic internal pipe (13) to be pushed through in order to adjust the length of the coupling bar.
  6. Coupling bar for a railway wagon according to Claims 1, 2 or 3,
    characterized
    in that when just one end tension rod part (8) is used per coupling rod end, the connection to the coupling bar (2) is implemented in an articulated or rigid fashion depending on the directional joint parameters.
  7. Coupling bar for a railway wagon according to at least one of the preceding claims,
    characterized
    in that the directional joint swing plates (9) are mounted in an articulated and axially displaceable fashion on the end tension rod parts (8).
