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 Claims 1 and 6.

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 Have power transmission with low weight and low costs in the Manufacture and maintenance of the coupling rod. The object is achieved according to the invention solved by the features of claims 1 and 6. Advantageous further developments of Invention emerge from the subclaims. It is essential to the invention that in Breakthroughs of the coupling rod around the coupling rod pivot points one at a time Coupling rod movable articulated support bearing is arranged, which is rigid, but detachable with the base via plug pairs of the freight car is connectable. It is also essential that the articulated support bearing has a centering opening on the pressure receiving side, which has a centering stump which from the middle of the directional joint plate, in which the spatial roll curve and the resulting spherical cap is integrated, protrudes. This is the central guidance of the directional joint support bearing, whereby through the jacket contour of the centering opening and of the truncated center a casual unrolling and tipping of the directional joint plate is given with a positive influence on the efficiency of the directional joint. At the Zugaufnahmeseite is a tension plate and a spring for tensile forces attached, wherein via a ball joint attachment on the directional joint support bearing and the counterpart on the Tensile washer supports an unobstructed tilting movement. The spring elements cause play-free tensioning of the joint parts as well as shock absorption and by the

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.

Im folgenden werden Ausführungsbeispiele der Erfindung anhand der Zeichnungen näher erläutert. Die Zeichnungen zeigen in:

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 coupling rod 3 according to the invention with a total of four articulation points. Compression forces F XL in the coupling rod 3 act in the specified direction.

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 breakthrough 19 of the coupling rod 3 is shown, wherein a directional joint plate 4 is fixedly connected to the coupling rod 3, which has a rolling curve 5 with a spherical surface and has a centering stub 8 with an insertion cone 9 in the longitudinal center of the coupling rod 3 which is received by a centering opening 10 in a directional joint support bearing 2. The articulated joint support bearing 2 is movably mounted in an opening 19 in the coupling rod 3, but is fixedly but releasably connected to an underframe 1 via a pair of plug pins 17. On the train side, the directional joint support bearing 2 has a ball joint attachment 7, which finds its counterpart in a tension plate 6, the joint contours following the radius around a central tipping point M1. After the traction sheave 6, which has a transverse guide cam 11 with a transverse play 20 for security against transverse displacement, a spring 13 for tensile forces is arranged. With its pretensioning force, this spring 13 ensures that all parts are supported in the opening 19 of the coupling rod 3 without play, for the required damping effect of the coupling rod 3 and for a smooth tilting and rolling process of the directional joint. The centering stub 8 which engages in the centering opening 10 in the articulated support bearing 2 has a lateral surface which follows a tilting radius R A around an initial tilting point M2 and the centering opening 10 has the same contour, however, which is subject to play. This design ensures adequate central positioning of the directional joint parts and optimal rolling of the rolling curve 5 through the directional joint support bearing 2. It is also conceivable that a conical contour is selected, in which case the cone angle is equal to or greater than a tangent T around the tilting radius R A to the rear Contour end point must be.

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 springs 13 for tensile forces, the tensile washers 6 with ball joint lugs 7 are present, the one in the directional joint support bearing 2 and the other in one Engage end plate 18. This design ensures that the parts are highly flexible in the opening 19 of the coupling rod 3.

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 Articulated plate 4, which is connected to the coupling rod 3 axially - longitudinally displaceable is a spring 14 for tensile and impact forces and a pressure-tensile washer 12 to be ordered. The advantage of this design is that both Zugwie shock forces can also be absorbed directly. It is also conceivable that instead of the socket pair 17 for torsionally rigid locking of Articulated joint support bearing 2 in the base frame 1, a single plug-in slide with e.g. Square cross-section is used. It would be advantageous to reduce the Number of locking parts. It is further proposed according to claim 6 that the Articulated joint plates 4 are designed as detachable individual parts and one each applicable radius R - Ri with at least half the size Obtain coupling rod length. This is advantageous because within a coupling rod 3 different radii and thus calottes are required for rolling curves 5.

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-adjustable coupling rod 3 with all-round directional joints is created, which is suitable for an automatic length change, has an effective directional joint and thus contributes to solving the problems of the running safety of light-weight vehicles and represents a weight and cost-saving solution.
This makes a contribution to improving the economy of freight transport, especially in combined transport.
