Description

Die Erfindung betrifft ein vereinfachtes Richtgelenk für Kuppelstangen von Eisenbahntragwageneinheiten gemäß dem Oberbegriff des Anspruches 1.The invention relates to a simplified articulated joint for coupling rods of railway wagon units according to the preamble of claim 1.

Richtgelenke für Kuppelstangen und an den Enden angeordneten Endzugstangenteilen, die von je einer Endplatte der Kuppelstange aus zentrisch durch die Richtgelenkplatten, die Stützlagerplatten sowie die Federelemente und die Endscheiben geführt sind, sind bereits vorgeschlagen worden.Straightening joints for coupling rods and arranged at the ends Endzugstangenteilen, which are guided by one end plate of the coupling rod from centric through the directional joint plates, the support bearing plates and the spring elements and the end plates have been proposed.

So zeigt EP-A-1.342.637 (& DE-C-102 10 059 ), die am 10.09.2003 veröffentlicht würde und somit nicht zu dem Stand der Technik gemäß Artikel 54 (2) EPÜ gehört, ein Richtgelenk in der vorstehend genannten Bauweise, bei dem Stützlagerplatten als Verbindungsteile zum Untergestell und die Richtgelenkplatten als Endteile der Kuppelstange über zug- und druckseitig angeordnete Federplatten längs verspannt werden.
Die Richtgelenkplatte ist zur Stützlagerplatte hin kugelkalottenförmig ausgebildete und der Kraftübertragungspunkt der Längskräfte rollt bei Ausschlägen der Kuppelstange nach den Außenbereichen, wodurch eine exakte Außermittigkeit und ein genaues Rückstellmoment gegeben ist. Damit wird es möglich, in Abhängigkeit der Gleisradien und den unterschiedlichen Beladezuständen die im Moment notwendigen Entlastungen der Radsatzführungskräfte und die vertikalen Kraftkomponenten zur Vergrößerung der Radkräfte relativ genau zu erzeugen.
Die Richtgelenkplatte sitzt mit ihrem Schaftteil teleskopartig und damit axial verstellbar auf dem Endrohr der Kuppelstange. Das genannte Schaftteil nimmt die druckseitigen Federscheiben auf.So shows EP-A-1342637 (& DE-C-102 10 059 ), which was published on 10.09.2003 and thus does not belong to the state of the art under Article 54 (2) EPC, a directional joint in the above construction, in the support bearing plates as connecting parts to the base frame and the directional joint plates as end parts of the coupling rod via train - And pressure side arranged spring plates are clamped longitudinally.
The directional joint plate is spherical cap-shaped trained for support bearing plate and the force transmission point of the longitudinal forces rolls in rashes of the coupling rod to the outside, creating an exact Außermittigkeit and an accurate restoring torque is given. This makes it possible, depending on the track radii and the different loading conditions to generate the currently necessary relieves the Radsatzführungskräfte and the vertical force components to increase the wheel forces relatively accurately.
The directional joint plate sits with its shaft part telescopically and thus axially adjustable on the tailpipe of the coupling rod. Said shaft part receives the pressure-side spring washers.

Neben dem Vorteil, dass man sowohl in vertikaler Richtung und insbesondere auch in horizontaler Richtung angepasst an den gerade zu durchfahrenden Gleisbogen und dem momentanen Ladezustand durch die Wahl des vertikalen sowie horizontalen Abrollradius stets die optimale Rückstellung bei Längsdruckkräften und die erforderliche Entlastung der Kraft zwischen Schiene und Spurkranz des führenden Rades und die Erhöhung der Radkraft des entlasteten Rades sichert, hat die vorgeschlagene Ausführung den Nachteil, dass die Teleskopführungen an den Enden der Kuppelstange teuer, gewichtserhöhend und insbesondere verschleißbehaftet und damit wartungsaufwendig sind.In addition to the advantage that both in the vertical direction and in particular also in the horizontal direction adapted to the just to be traversed curve and the current state of charge by the choice of vertical and horizontal Abrollradius always the optimal provision for longitudinal compressive forces and the required relief of the force between rail and Wheel flange of the leading wheel and the increase in the wheel force of the unloaded wheel ensures, the proposed embodiment has the disadvantage that the telescopic guides at the ends of the coupling rod expensive, weight-increasing and in particular wear-prone and thus are maintenance-consuming.

Weiterhin sind hinreichend Lösungen bekannt, bei denen Kuppelstangen mit ihren Endzugstangen einfach über druck- und zugseitige runde Federscheiben an einer Stützlagerplatte, die wieder zwischen zwei Kupplungsträgern eines Wagens befestigt ist, angeordnet sind.
Beim Ausschwenken der Kuppelstangen werden die vorgespannten druckseitigen Federscheiben keilförmig verspannt, und die wirkenden Längsdruckkräfte vergrößern diese Verspannung und die Krafteinleitung in die Kuppelstange erfolgt außermittig, wodurch auch Rückstellmomente erzeugt werden.Furthermore, sufficient solutions are known in which coupling rods with their Endzugstangen simply via pressure and zugseitige round spring washers on a support bearing plate, which is again secured between two coupling members of a car, are arranged.
When swinging the coupling rods biased pressure-side spring washers are wedge-shaped braced, and the acting longitudinal pressure forces increase this tension and the introduction of force into the coupling rod takes place off-center, which also restoring moments are generated.

Der Nachteil besteht jedoch darin, dass die Außermittigkeit der Kraftübertragung, die von der Flächenresultierenden der keilförmig deformierten Federscheibe abhängt, gering ist und nicht in den nahen Randbereichen der Scheiben erfolgt.The disadvantage, however, is that the eccentricity of the transmission, which depends on the surface resulting of the wedge-shaped spring washer, is small and does not occur in the near edge regions of the discs.

Auch vergrößerte Federscheibendurchmesser sowie eine Erhöhungen der Federwerkstoffhärte bringen keine optimalen Richtgelenkwirkungen, zumal der Federwerkstoff an der Keilspitze Überbesanspruchungen ausgesetzt ist.
Diese Gelenkart ist nur bei Fahrzeugen, die eine geringe Richtgelenkleistung benötigen zum Beispiel Wagen mit höherem Gewicht oder kürzeren Wagenlängenparametem, anwendbar.Also, enlarged spring washer diameter and an increase in the spring material hardness bring no optimal directional joint effects, especially since the spring material is exposed to the wedge tip Überbesansprungen.
This type of articulation is only applicable to vehicles requiring low articulation performance, such as higher weight cars or shorter car length parameters.

Aufgabe der Erfindung ist es, ein vereinfachtes Richtgelenk für Kuppelstangen zu schaffen, welches die Nachteile der bekannten Lösungen vermeidet und die Anforderungen an Richtgelenke mit großer Richtgelenkwirkung für leichtgewichtige Eisenbahntragwagen und der Laufsicherheit unter Wirkung von Längsdruckkräften zuverlässig gewährleistet bei einem geringeren Unterhaltungsaufwand im Betrieb und Senkung des Herstellungsaufwandes bei Geringhaltung des Eigengewichtes. The object of the invention is to provide a simplified articulated joint for coupling rods, which avoids the disadvantages of the known solutions and reliably ensures the requirements for straightening joints with great directional joint effect for lightweight railway wagons and running safety under the action of longitudinal compressive forces at a lower maintenance cost in operation and reduction of Production costs while keeping the dead weight.

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

Erfindungswesentlich ist, dass die druckseitigen Federplattendämpfungselemente, eingespannt zwischen den Endflächen der Kuppelstange und den Stützlagerplatten des Richtgelenkes innerhalb eines Stützkäfiges an dessen äußeren Rändern sich Abstützund Kipppunkte befinden, die einen solchen Abstand "a" zur Anlagefläche der Stützlagerplatte aufweisen, dass sie beim Ausschwenken der Kuppelstange in vertikaler und/oder horizontaler Richtung und dem gleichzeitigen Wirken anfänglicher Längsdruckkräfte "LDK" als Kraftübertragungspunkte zwischen Kuppelstange und Stützlagerplatte zur Anlage kommen, angeordnet sind,
und dass die Anlage der Abstütz- und Kipppunkte des Stützkäfiges an die Stützlagerplatte ab einem horizontalen Kuppelstangenausschlag erfolgt, der bei europäischen Normalspurbahnen im definierten Bereich der Gleisbögen mit kleinem Gleisradiuns von ca. R = 400 bis 300 m liegt und einem gleichzeitigen Wirken einer anfänglichen Längsdruckkraft "LDK" von etwa 1/3 bis ½ der Maximalkraft der im Gegen/Vollbogen verlangten Mindestlängsdruckkraft enspricht.It is essential to the invention that the pressure-side spring plate damping elements, clamped between the end faces of the coupling rod and the support bearing plates of the directional joint within a support cage at its outer edges are Abstützund tilting points, which have such a distance "a" to the contact surface of the support bearing plate that they swing when swinging the coupling rod are arranged in the vertical and / or horizontal direction and the simultaneous action of initial longitudinal pressure forces "L DK " as force transmission points between the coupling rod and the support bearing plate,
and that the attachment of the supporting and tilting points of the support cage to the support bearing plate from a horizontal Kuppelstangenausschlag that is in European standard gauge railways in the defined area of the track curves with small Gleisradiuns of about R = 400 to 300 m and a simultaneous action of an initial longitudinal compressive force " L DK "of about 1/3 to ½ of the maximum force corresponds to the requested in the counter / full arc longitudinal compressive force.

Darüber hinaus ist erfindungsgemäß, dass der Stützkäfig in horizontaler Richtung von seinem Mittelpunkt aus verbreiterte Ränder aufweist, die Abrollkurven zum Abrollen an der Stützlagerplatte besitzen.In addition, according to the invention, that the support cage in the horizontal direction from its center has widened edges, which have rolling curves for rolling on the support bearing plate.

In den übrigen Ansprüchen werden weitere vorteilhafte Ergänzungen der Erfindung dargelegt.
Der besondere Vorteil des vorstehend vorgeschlagenen vereinfachten Richtgelenkes für Kuppelstangen ist seine Hochleistungsrichtgelenkwirkung, erzielt durch weitgehenden Verzicht auf eine über ein Schaftteil axial geführte Richtgelenkplatte mit Kugelkalottenteil. Durch das Verwenden eines Stützkäfiges an der Richtgelenkplatte und des Einsetzens der Abstütz- und Kipppunkte oder des ringförmigen Randes nach dem Erreichen eines Kuppelstangenausschlages ab etwa 400 bis 300 m Gleisradius und einer anfänglichen Längsdruckkraft von 1/3 bis ½ der ertragbaren Längsdruckkraft erfolgt eine Zweiteilung des Lastwirkungsbereiches in einen Normallastbereich und einem außergewöhnlichen Lastbereich im engen Bogen mit hohen Längsdruckkräften.In the remaining claims further advantageous additions of the invention are set forth.
The particular advantage of the above-proposed simplified directional joint for coupling rods is its high-performance joint effect, achieved by largely dispensing with a guided over a shaft member axially rectilinear plate with spherical part. By using a support cage on the directional-link plate and the insertion of the supporting and tipping points or the annular rim, after reaching a coupling rod-shock from about 400 to 300 meters track radius and an initial longitudinal compressive force from 1/3 to ½ of the longitudinal compressive force, a division of the load acting portion is carried out in a normal load range and an exceptional load range in a tight arc with high longitudinal compressive forces.

Im Normallastbereich mit großen Gleisradien wirkt druckseitig das geringe, aber hier ausreichende Rückstellmoment, erzeugt über die Härte der Federplatte.
Im außergewöhnlichen Bereich wirken die "außergewöhnlichen" Einrichtungen, bestehend aus Abstütz- und Kipppunkten sowie aus einer Abrollkurve über den Rand der Richtgelenkplatte hinaus bzw. dem Eingreifen von Hilfsdruckfedern.
Im Normallastbereich, der im wesentlichen das gerade Gleis und flache Gleisbögen ausmacht, steht daneben die volle Dämpfungskapazität der Druckfederelemente weitgehends zur Verfügung. Die einsetzende vergrößerte Eigenverspannung ab einem Gleisradius von 400 bis 300m wirkt für die leichten Tragwagen Laufruhe verbessernd in Gleisen mit geringeren Radien bis R = 250 m entsprechend den Forderungen des internationalen Eisenbahnverbandes UIC.In the normal load range with large track radii on the pressure side, the low, but here sufficient restoring moment, generated by the hardness of the spring plate.
In the exceptional area, the "extraordinary" facilities, consisting of supporting and tilting points and a rolling curve over the edge of the directional joint plate addition or the intervention of auxiliary pressure springs.
In the normal load range, which essentially makes up the straight track and flat track curves, next to the full damping capacity of the compression spring elements is largely available. The onset of increased self-tension from a track radius of 400 to 300m acts for the light wagons smoothness improving in tracks with lower radii up to R = 250 m in accordance with the requirements of the International Union of Railways UIC.

Die Figuren 1 bis 5 zeigen jeweils die Endpartien der Kuppelstangen 2, die über Anschläge mit dem Tragwagenuntergestell 1 in Verbindung stehen.
Die Kuppelstangen 2 tragen an ihren Enden Richtgelenkplatten 3 mit Endlächen 7, die als Stützkäfig 8 fungieren und einen Rand 9 besitzen, der die Anlage des jeweiligen Abstütz- und Kipppunktes 10 beim Ausschwenken der Kuppelstange 2 an der Stützlagerplatte 4 übernimmt.The FIGS. 1 to 5 show in each case the end parts of the coupling rods 2, which are connected via stops with the caravan base frame 1 in connection.
The coupling rods 2 carry at their ends directional hinge plates 3 with Endlächen 7, which act as a support cage 8 and have an edge 9, which takes over the system of the respective support and tilting point 10 during pivoting of the coupling rod 2 on the support bearing plate 4.

Ein Kuppelstangenendzugteil 5, befestigt am Endteil der Kuppelstange 2 verbindet selbige über Federplattendämpfungselemente 6 mit der Stützlagerplatte 4, die wiederum über Anschläge die unmittelbare Verbindung mit dem Tragwagenuntergestell 1 darstellt. Die Kuppelstangenendzugteile 5 sind dabei beweglich in der Stützlagerplatte 4 gelagert, wobei der Schwenkpunkt 16 innerhalb oder außerhalb der Dicke der Stützlagerplatte 4 liegen kann.A Kuppelstangenendzugteil 5, attached to the end portion of the coupling rod 2 connects selbige about spring plate damping elements 6 with the support bearing plate 4, which in turn represents via stops the immediate connection with the caravan base frame 1. The Kuppelstangenendzugteile 5 are movably mounted in the support bearing plate 4, wherein the pivot point 16 may be within or outside the thickness of the support bearing plate 4.

Zwischen der Endfläche 7 an der Kuppelstange 2, die auch gleichzeitig die Innenfläche der Richtgelenkplatte 3 darstellt, und der Auflagefläche 13 der Stützlagerplatte 4 sind die druckseitigen Federplattendämpfungselemente 6 und hinter der Stützlagerplatte 4 sind solche zur Aufnahme der Zugkräfte eingespannt angeordnet.Between the end face 7 on the coupling rod 2, which also simultaneously represents the inner surface of the directional joint plate 3, and the support surface 13 of the support bearing plate 4, the pressure-side spring plate damping elements 6 and behind the support bearing plate 4 are arranged such that they are clamped for receiving the tensile forces.

Erfindungsgemäß werden die druckseitigen Federplattendämpfungselemente 6 in der Richtgelenkplatte 3, die als Stützkäfig 8 ausgeführt ist, angeordnet, so dass zwischen dem Rand 9 bzw. dem Abstütz- und Kipppunkt 10 und der Auflagefläche 13 der Stützlagerplatte 4 ein Maß "a" gegeben ist.According to the invention, the pressure-side spring plate damping elements 6 in the directional joint plate 3, which is designed as a support cage 8, arranged so that between the edge 9 and the support and tilting point 10 and the support surface 13 of the support bearing plate 4 is given a measure "a".

Beim zentrischen Zusammendrücken der Federplattendämpfungselemente 6 im geraden Gleis und in solchen mit großen Gleisradien, die im internationalen Eisenbahnverband mit bis zu R = 400 m definiert sind, als die weitestgehenden Belastungsfälle, steht dabei bis zum Ausschlag der Kuppelstange 2 entsprechend den vorgenannten Gleisbedingungen die volle Feder- und Dämpfungskapazität zur Verfügung.
Als Rückstellmoment wirkt in diesem "Normallastbereich" lediglich selbiges aus der keilförmigen Verspannung der druckseitigen Federplattendämpfungselemente 6.When centric compression of the spring plate damping elements 6 in the straight track and in those with large track radii, which are defined in the international railway association with up to R = 400 m, as the most extensive load cases, stands until the rash of the coupling rod 2 according to the aforementioned track conditions the full spring - and damping capacity available.
As restoring moment acts in this "normal load range" only selbiges from the wedge-shaped tension of the pressure-side spring plate damping elements. 6

Weiter sind die Federplattendämpfungselemente 6 und die Druckfederwege so dimensioniert, dass das Maß "a" einen freien Kuppelstangenausschlag bis zu Gleisbögen mit Radien von ca.400 bis 300 m garantiert beim gleichzeitigen Wirken einer anfänglichen Längsdruckkraft "LDK" von 1/3 bis ½ der geforderten ertragbaren Längsdruckkraft LDK im Vollbogen mit einem Gleisradius von 150 m.Further, the spring plate damping elements 6 and the compression spring means in such dimensioned that the dimension "a" has a free coupling rod extension stroke up to curves with radii of about 400 to 300 m ensures the simultaneous action of an initial longitudinal compressive force "L DK" 1/3 to ½ of the required continuous longitudinal compressive force L DK in full curve with a track radius of 150 m.

Nach dem Überschreiten der anfänglichen Längsdruckkraft "LDK" und dem Durchfahren von Gleisbögen < R = 300 m beginnt der "außergewöhnliche Lastbereich". Dabei kommen die weit von der Kuppelstangenlängsmitte angeordneten Abstütz- und Kipppunkte 10 sowie die Abrollkurve 11 mit ihrem Abrolleffekt oder die Hilfsdruckfeder 14 zur Anlage. Sie erzeugen ab diesem Zeitpunkt zunehmend höhere Rückstellmomente, die proportional den ansteigenden Radlagerquerkräften "Hy" zwischen Spurkranz und Schiene entgegenwirken.
Das Gleiche erfolgt in vertikaler Richtung, wo durch die Entstehung von Vertikalkomponenten aus dem Richtgelenkt die vertikalen Radkräfte der entlasteten Achsen ausgleichend belastet werden.After exceeding the initial longitudinal compressive force "L DK " and passing through track curves <R = 300 m, the "extraordinary load range" begins. In this case, the supporting and tilting points 10, which are arranged far from the longitudinal center of the coupling rod, as well as the rolling curve 11 come into contact with their rolling-off effect or the auxiliary pressure spring 14. From this point on they produce increasingly higher restoring moments, which counteract proportionally the increasing wheel bearing transverse forces "H y " between wheel flange and rail.
The same is done in the vertical direction, where the vertical wheel forces of the relieved axles are compensated by the emergence of vertical components from the directionally deflected.

Diese getrennte Wirkungsweise zwischen "Normal- und außergewöhnlichem Lastbereich" macht eine Vereinfachung der Ausbildung des Richtgelenkes ohne durchgehende Abrollflächen und ohne die Verwendung von Teleskoprohren an der Richtgelenk-platte möglich.This separate mode of action between "normal and exceptional load range" makes a simplification of the training of the directional joint without continuous rolling surfaces and without the use of telescopic tubes on the directional joint plate possible.

In Figur 1 ist ein Richtgelenk, ausgestattet mit einem ringförmigen Rand 9 am Stützkäfig 8 dargestellt.In FIG. 1 is a directional joint, equipped with an annular rim 9 shown on the support cage 8.

Figur 2 zeigt eine Richtgelenkplatte 3 mit Stützkäfig 8 mit getrennt ausgeführten Abstütz- und Kipppunkten 10 für vertikale sowie horizontale Richtgelenkwirkung. FIG. 2 shows a directional joint plate 3 with support cage 8 with separately executed support and tilting points 10 for vertical and horizontal directional joint effect.

Figur 3 zeigt die Anordnung eines verbreiterten Randes 9 des Stützkäfiges 8 mit anschließender Abrollkurve 11, vorzugsweise zur Vergrößerung der horizontalen Stabilisierung. FIG. 3 shows the arrangement of a widened edge 9 of the support cage 8 with subsequent rolling curve 11, preferably for increasing the horizontal stabilization.

Das Maß "a" zur Stützlagerplatte 4, welches sich zusammensetzt aus dem Kippweg "SK" der Richtgelenkplatte 3 und deren Kipppunkte plus dem Federweg "SF" aus der anfänglichen Längsdruckkraft "LDK", vergrößert sich im Anteil des Kippweges mit dem Ausschlagwinkel "αV" oder "αH" der Kuppelstange 2.The measure "a" to the support bearing plate 4, which is composed of the Kippweg "S K " of the directional joint plate 3 and their tilting points plus the spring travel "S F " from the initial longitudinal compressive force "L DK " increases in proportion of Kippweges with the deflection angle "α V " or "α H " of the coupling rod 2.

In der Ausführung der Figur 4 werden horizontal stabilisierende Hilfsdruckfedern 14 angeordnet, wodurch auch eine elastische Kraftübertragung in Extremkurven gegeben ist. Dabei ist es auch denkbar, dass die Hilfsdruckfedern 14 bei Verwendung einer weichen Feder mit einer flachen statischen Kraft-Weg-Kennlinie von Anbeginn, an der Stützlagerplatte 4 anliegt und bei zentrischer Krafteinleitung auch Längsdruckkräfte "LDK" übernimmt.In the execution of FIG. 4 horizontally stabilizing auxiliary pressure springs 14 are arranged, whereby an elastic force transmission is given in extreme curves. It is also conceivable that the auxiliary compression springs 14 when using a soft spring with a flat static force-displacement curve from the beginning, rests on the support bearing plate 4 and with centric force introduction and longitudinal pressure forces "L DK " takes over.

Vorteilhaft ist auch vorgesehen, die druckseitigen Federplattendämpfungselemente 6 zur Verbesserung der Richtgelenkwirkung mit größeren Durchmessern auszuführen als die der zugseitigen Federplattendämpfungselemente 6.
Vorgesehen ist weiter die Anzahl der druckseitigen Federplattendämpfungselemente 6 gegenüber der Anzahl der zugseitigen Federplattendämpfungselemente 6 klein zu halten.It is also advantageous to design the pressure-side spring plate damping elements 6 to improve the directional joint effect with larger diameters than those of the tension-side spring plate damping elements 6.
It is further provided that the number of pressure-side spring plate damping elements 6 with respect to the number of tension-side spring plate damping elements 6 to keep small.

Wie Figur 1 zeigt, ist bei druckseitigen Federplattendämpfungselementen 6, die etwa das doppelte Höhenmaß des international festgelegten UIC-Richtgelenkes besitzt, die Lagerung der Kuppelstangenendzugteile 5 in der Kuppelstange 2 über einen Gelenkpunkt 15 zur Vermeidung erhöhter Biegebeanspruchungen möglich.As FIG. 1 shows, is at pressure-side spring plate damping elements 6, which has about twice the height of the internationally fixed UIC directional joint, the storage of Kuppelstangenendzugteile 5 in the coupling rod 2 via a hinge point 15 to avoid increased bending stresses possible.

Es ist auch denkbar, dass die Teile des Stützkäfiges 8 reziprok an der Stützlagerplatte 4 angeordnet sein können.It is also conceivable that the parts of the support cage 8 can be arranged reciprocally on the support bearing plate 4.

Bei der Verwendung von Kuppelstangen 2 gemäß Figur 5, die permanent in Schrägstellung angeordnet ausgeführt sind, sind die Anschlagteile 12 im Winkel der permanenten Schrägstellung "αVSK" zur Sicherung des gleichmäßigen Abstandes "a" unterschiedlich lang ausgeführt, oder die vertikalen Stützlagerplatten besitzen entsprechende Ausarbeitung.When using coupling rods 2 according to FIG. 5 , Which are designed to be permanently arranged in an inclined position, the stop members 12 at the angle of the permanent inclination "α VSK " for securing the uniform distance "a" run different lengths, or the vertical support bearing plates have appropriate elaboration.

Weiter ist vorgesehen, dass die Kuppelstangen 2 zwischen den End- und Mittelwagen die nicht extrem leicht ausgeführt sind, nur an dem Ende zum Endwagen hin mit Stützlagerkäfigen 8 und deren Anbauteilen , die die Funktion des Abstützens und Kippens übernehmen, ausgerüstet sind. Das bedeutet, dass in diesem Falle auch Kuppelstangen zwischen den Mittelwagen symmetrisch an beiden Enden ohne Stützkäfig 8 verwendet werden können.
Denkbar ist auch eine Kuppelstange 2 zwischen End- und Mittelwagen, die an ihren beiden Enden unterschiedlich große Abstütz- und Kipppunkte 10 mit unterschiedlichen Kipphebelarmen besitzt. Dabei sind die größeren Kipphebelarme am Endwagenende angeordnet.It is further provided that the coupling rods 2 between the end and middle cars are not carried out extremely light, only at the end to end car out with support bearing cages 8 and their attachments that take over the function of supporting and tilting equipped. This means that in this case also coupling rods between the central car can be used symmetrically at both ends without support cage 8.
It is also conceivable a coupling rod 2 between the end and middle cars, which has different sized support and tilting points 10 with different Kipphebelarmen at both ends. The larger Kipphebelarme are arranged at Endwagenende.
