Description
Die Erfindung bezieht sich auf eine längenanpaßbare Kuppelstange mit allseitig
wirkenden Richtgelenken für Schienenfahrzeuge gemäß den Oberbegriffen der
Patentansprüche 1 und 6.The invention relates to a length-adjustable coupling rod with all sides
acting directional joints for rail vehicles according to the generic terms of
Zur Ladelängenanpassung insbesondere für Tragwageneinheiten für den Kombinierten Ladungsverkehr sind Kuppelstangen bekannt, bei denen das Umstecken an mehrfach vorhandenen Gelenkpunkten innerhalb der Länge der Kuppelstangen und Aufnahmepunkten im Untergestell erzielt wird. Dabei tragen die ungeteilten Kuppelstangen Kugelgelenklager, die einen freien Kuppelstangenanschlag sichern. Durch die Nachsteckmöglichkeit können geteilte, z.B. teleskopierbare Stangen, die bei den auftretenden Stoßkräften von bis zu 200 t je Stange knickempfindlich sind und entsprechend schwer ausgeführt werden müssen, vermieden werden. Mit Kuppelstangen ausgerüstete Güterwagen müssen entsprechend den internationalen Vorschriften enge Vollbögen beim gleichzeitigen Wirken von Drucklängskräften in Höhe von mindestens 50 t resultierend aus Nachschiebevorgängen entgleisungssicher durchlaufen können. Kuppelstangen mit Kugelgelenken erfordern hohe Eigengewichte, um die Forderungen der Laufsicherheit zu erfüllen. Nachsteckstangen sind wiederum vorteilhaft notwendig, da hierbei eine weitgehendst automatische Längenumstellung von den angrenzenden Fahrzeugteilen aus eisenbahntechnisch günstig angesteuert werden kann. Vorhandene bekannte Richtgelenkkuppelstangen gehen alle von einer Anordnung des Richtgelenkes an den Kuppelstangenenden aus. Der Aufbau ist in der Regel durch die Anwendung von gelenkbolzenbefestigten Kuppelstangenenden über Zugbügel, der einen Teleskopfederapparat umschließt und sich über lose oder feste Stützlager zwischen den Kupplungsträgern abstützt, gekennzeichnet.For loading length adjustment, especially for wagon units for the combined vehicle Cargo traffic are known coupling rods, in which the plugging in multiple times existing articulation points within the length of the coupling rods and Pick-up points in the base frame is achieved. The undivided wear Coupling rods Ball joint bearings that ensure a free coupling rod stop. Due to the possibility of replenishing, e.g. telescopic poles that are sensitive to buckling at the impact forces of up to 200 t per bar and must be carried out accordingly difficult to be avoided. Freight cars equipped with coupling rods must comply with the international Regulations tight full arches with simultaneous action of longitudinal thrust forces in Height of at least 50 t resulting from the reloading process can go through. Coupling rods with ball joints require high dead weights, to meet the requirements of running safety. Extension rods are again Advantageously necessary, since this involves a largely automatic length change Controlled cheaply from the adjacent vehicle parts from railway technology can be. Existing known articulated coupling rods all go from one Arrangement of the directional joint on the coupling rod ends. The structure is in the Usually through the use of coupling rod-attached coupling rod ends Drawbar that encloses a telescopic spring device and is loose or fixed Support bearing supported between the clutch carriers, marked.
Diese Lösungen an Kuppelstangenenden sind für eine längenveränderliche Nachsteck - Kuppelstange ungeeignet. These solutions at the ends of the coupling rods are for a variable length extension - Coupling rod unsuitable.
In der DE 199 44 754.3 wurde bereits eine Lösung vorgeschlagen, bei der am Ende einer Kuppelstange eine Zugstange als Fortführrung derselben angeordnet ist, welche durch ein Stützlager geführt ist und mit einer Starr oder axialverschiebbaren Richtgelenkplatte verbunden ist, wobei die Lagerung der Zugstange im Stützlager über einen Zentrierstumpf erfolgt. Diese vorgesehene Ausführung hat ebenfalls den Nachteil, daß sie für eine längenveränderliche Nachsteckkuppelstange nicht geeignet ist.A solution has already been proposed in DE 199 44 754.3, in which a Coupling rod a pull rod is arranged as a continuation of the same, which by a support bearing is guided and with a rigid or axially displaceable articulated plate is connected, the storage of the tie rod in the support bearing via a Centering stump takes place. This design also has the disadvantage that it is not suitable for a variable plug-in coupling rod.
In EP-A-727338 wird eine längenanpaßbare Kuppelstange für Schienenfahrzeuge beschrieben, bei der die Längenveränderung durch Umstecken an den vorhandenen Kuppelstangen-Gelenkpunkten und den Aufnahmepunkten im Untergestell erfolgt.EP-A-727338 describes a length-adjustable coupling rod for rail vehicles described in which the change in length by changing the existing Coupling rod articulation points and the mounting points in the base.
In GB-A-417082 wird eine Kuppelstange verwendet, die sich druckseitig elastisch gegen die Stützlagerteile eines teleskopartigen Federungs- und Dämpfungselementes über kugelförmige Stoßflächen gelenkig abstützt. Die Übertragung der zugseitigen Kräfte erfolgt über eine durch den Wagen verlaufende Zugstange, die am Ende an der Kuppelstange gelenkartig angeschlossen ist.In GB-A-417082 a coupling rod is used which is elastic on the pressure side against the support bearing parts of a telescopic suspension and damping element supported in an articulated manner via spherical abutting surfaces. The transmission of the train side The forces are exerted by a pull rod running through the carriage, which ends at the Coupling rod is connected in an articulated manner.
Aufgabe der Erfindung eine längenanpaßbare Kuppelstange der eingangs genannten Art
mit allseitigen Richtgelenken zu schaffen, die für eine weitgehendst automatische
Umstellung der Ladelangen mit selbsttätigem Einrasten der Kupplungsbolzen geeignet
ist und welche zur Lösung der Probleme der Entgleisungssicherheit stabilisierende
Gelenke mit hohem Wirkungsgrad und einer weitgehendst geradliniger
Kraftdurchleitung besitzen bei geringer Eigenmasse und niedrigen Kosten in der
Herstellung und Unterhaltung der Kuppelstange. Die Aufgabe wird erfindungsgemäß
durch die Merkmale der Patentansprüche 1 und 6 gelöst. Vorteilhafte Weiterbildungen der
Erfindung gehen aus den Unteransprüchen hervor. Erfindungswesentlich ist, daß in
Durchbrüchen der Kuppelstange um die Kuppelstangengelenkpunkte je ein zur
Kuppelstange bewegliches Richtgelenkstützlager
angeordnet ist, welches über Steckbolzenpaare starr, jedoch lösbar mit dem Untergestell
des Güterwagens verbindbar ist. Wesentlich ist weiterhin, daß das Richtgelenkstützlager
an der Druckaufnahmeseite eine Zentrieröffnung besitzt, die einen Zentrierstumpf, der
aus der Mitte der Richtgelenkplatte, in welche die räumliche Abrollkurve und die dabei
entstehende Kugelkalotte integriert ist, herausragt. Dadurch ist die zentrische Führung
des Richtgelenkstützlagers gesichert, wobei durch die Mantelkontur der Zentrieröffnung
und des Zentierstumpfes ein zwangloses Abrollen und Auskippen der Richtgelenkplatte
gegeben ist mit positivem Einfluß auf den Wirkungsgrad des Richtgelenkes. An der
Zugaufnahmeseite ist eine Zugscheibe und eine Feder für Zugkräfte angebracht, wobei
über einen Kugelgelenkansatz am Richtgelenkstützlager und dem Gegenstück an der
Zugscheibe eine ungehinderte Kippbewegung unterstützt wird. Die Federelemente
bewirken eine spielfreie Verspannung der Gelenkteile sowie eine Stoßdämpfung und
durch das Object of the invention a length-adjustable coupling rod of the type mentioned
with all-round directional joints to create a largely automatic
Conversion of the loading lengths with automatic engagement of the coupling bolts is suitable
and which is stabilizing to solve the problems of derailment security
Joints with high efficiency and a largely straight line

Manufacture and maintenance of the coupling rod. The object is achieved according to the invention
solved by the features of
Einschnappen der Zugscheibe in den Kugelgelenkansatz wird die sichere Halterung der Einzelelemente in dem Durchbruch der Kuppelstange gewährleistet. Es wird auch eine Lösung vorgeschlagen, bei der die Feder sowohl für Zug- als auch für Druckkräfte Anwendung findet, wobei bei zugseitiger Belastung Zuganschlagarme, die an dem Richtgelenkstützlager angebracht sind, in Aktion treten.Snapping the traction sheave into the ball joint attachment becomes the secure holder of the individual elements in the opening in the coupling rod. It will also proposed a solution in which the spring for both pull and Compressive forces are used, with tension stop arms that are attached to the directional joint support bearing, take action.
Die Erfindung sichert mit den vorgeschlagenen Einbauverhältnissen und der geradlinigen Kraftdurchleitung sowie den Bewegungsmöglichkeiten des Richtgelenkes eine hohe Effektivität.The invention ensures with the proposed installation conditions and rectilinear power transmission and the movement possibilities of the directional joint high effectiveness.

Die Fig.1 zeigt in einer Draufsicht die Hälfte einer erfindungsgemäßen Kuppelstange
3 mit insgesamt vier Gelenkpunkten. Druckkräfte FXL in der Kuppelstange 3 wirken
in der angegebenen Richtung.1 shows a top view of half of a
In den Fig. 2 und 3 ist ein Duchbruch 19 der Kuppelstange 3 dargestellt, wobei
eine Richtgelenkplatte 4 fest mit der Kuppelstange 3 verbunden ist, die eine
Abrollkurve 5 mit kalottenförmiger Oberfläche aufweist und in der Längsmitte der
Kuppelstange 3 einen Zentrierstumpf 8 mit Einführkegel 9 besitzt, der von einer
Zentrieröffnung 10 in einem Richtgelenkstützlager 2 aufgenommen wird. Das
Richtgelenkstützlager 2 ist beweglich in einem Durchbruch 19 der Kuppelstange 3
gelagert, jedoch mit einem Untergestell 1 fest aber lösbar über ein Steckbolzenpaar
17 verbunden. Zugseitig besitzt das Richtgelenkstützlager 2 einen Kugelgelenkansatz
7, der sein Gegenstück in einer Zugscheibe 6 findet, wobei die Gelenkkonturen dem
Radius um einen mittleren Kippunkt M1 folgen. Nach der Zugscheibe 6, die zur
Sicherheit gegen ein Querverschieben einen Querführungsnocken 11 mit einem
Querspiel 20 aufweist, ist eine Feder 13 für Zugkräfte angeordnet. Diese Feder 13
sorgt mit ihrer Vorspannkraft für eine spielfreie Lagerung aller Teile im Durchbruch
19 der Kuppelstange 3, für den erforderlichen Dämpfungseffekt der Kuppelstange 3
und für einen weichen Kipp- und Abrollvorgang des Richtgelenkes. Der in die
Zentrieröffnung 10 im Richtgelenkstützlager 2 eingreifende Zentrierstumpf 8 besitzt
eine Mantelfläche, die einem Kippradius RA um einen anfänglichen Kippunkt M2
folgt und die Zentrieröffnung 10 weist dieselbe, jedoch spielbehaftete Kontur auf.
Diese Gestaltung sichert eine ausreichende zentrische Lagerung der Richtgelenkteile
und ein optimales Abrollen der Abrollkurve 5 durch das Richtgelenkstützlager 2. Es
ist auch denkbar, daß eine kegelförmige Kontur gewählt wird, wobei dann der
Kegelwinkel gleich oder größer einer Tangente T um den Kippradius RA zum
hinteren Konturendpunkt sein muß.2 and 3, a
Gemäß Fig. 4 besteht eine weitere Ausgestaltungsmöglichkeit darin, daß rechts- und
linksseitig der Federn 13 für Zugkräfte die Zugscheiben 6 mit Kugelgelenkansätzen 7
vorhanden sind, die einmal in das Richtgelenkstützlager 2 und zum anderen in eine
Endplatte 18 eingreifen. Diese Ausführung sichert eine hohe Gelenkigkeit der Teile
im Durchbruch 19 der Kuppelstange 3.According to FIG. 4, there is a further design option that right and
on the left side of the
Entsprechend Fig.5 besitzt das Richtgelenkstützlager 2 Zuganschlagarme 15, wobei
zwischen dem Richtgelenkstützlager 2 und den Zuganschlagarmen 15 die
Richtgelenkplatte 4, die mit der Kuppelstange 3 axial - längsverschiebbar verbunden
ist, eine Feder 14 für Zug- und Stoßkräfte sowie eine Druck-Zugscheibe 12
angeordnet werden. Der Vorteil dieser Ausführung besteht darin, daß sowohl Zugwie
auch Stoßkräfte direkt gedämpft aufgenommen werden. Es ist weiter denkbar,
daß anstelle des Steckbolzenpaares 17 zur drehsteifen Arretierung des
Richtgelenkstützlagers 2 im Untergestell 1 ein einzelner Steckschieber mit z.B.
Vierkantquerschnitt Anwendung findet. Vorteilhaft wäre hierbei eine Reduzierung der
Anzahl der Arretierungsteile. Weiter wird gemäß Anspruch 6 vorgeschlagen, daß die
Richtgelenkplatten 4 als lösbare Einzelteile ausgeführt werden und einem jeweilig
zutreffenden Richtgelenkradiuses R - Ri mit mindestens der Größe der halben
Kuppelstangenlänge erhalten. Dies ist vorteilhaft, da innerhalb einer Kuppelstange 3
unterschiedliche Radien und damit Kalotten für Abrollkurven 5 erforderlich sind.According to Figure 5, the articulated support bearing 2 Zuganschlagarme 15, wherein
between the articulated support bearing 2 and the Zuganschlagarmen 15 die
Mit den vorgenannten Ausführungen wird eine längenanpaßbare Kuppelstange 3 mit
allseitig wirkenden Richtgelenken geschaffen, die für eine automatische
Längenumstellung geeignet ist, ein effektives Richtgelenk besitzt und damit zur
Lösung der Probleme der Laufsicherheit leichtgewichtiger Wagen beiträgt sowie eine
gewichts- und kostensparende Lösung darstellt.
Damit wird ein Beitrag geleistet zur Verbesserung der Ökonomie des
Gütertransportes, insbesondere im Kombinierten Verkehr. With the aforementioned designs, a length-
