Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft eine Gelenkkupplung für Schienenfahrzeuge, bei welcher eine Kupplungslasche mittels eines sphärischen Lagers in einer Kupplungsgabel gelagert ist.The invention relates to an articulated coupling for rail vehicles, in which a coupling tab is mounted by means of a spherical bearing in a clutch fork.

Hintergrund der ErfindungBackground of the invention

Eine Gelenkkupplung der eingangs genannten Art ist beispielsweise aus der US 5,172,819 A oder aus der DE 101 53 460 A1 bekannt. Es handelt sich hierbei um eine Kupplung zur semipermanenten Verbindung von Waggons. Es werden beispielsweise Einheiten von zehn Waggons zusammengestellt, die in der Regel nur zu Wartungszwecken getrennt werden. Die semipermanenten Verbindungen zwischen den Waggons sollen dazu beitragen, die Auswirkungen von Schlagkräften zu reduzieren, die unter den Stoßbedingungen des Zugbetriebs auf einen Waggon einwirken.An articulated coupling of the type mentioned is, for example, from the US 5,172,819 A or from the DE 101 53 460 A1 known. This is a coupling for semi-permanent connection of wagons. For example, units of ten cars are assembled, which are usually separated only for maintenance purposes. The semi-permanent connections between the wagons should help to reduce the impact of impact forces acting on a wagon under the impact conditions of train operation.

Aufgabe der ErfindungObject of the invention

Der Erfindung liegt die Aufgabe zugrunde, eine für Schienenfahrzeuge geeignete Gelenkkupplung anzugeben, welche sich sowohl durch eine beanspruchsgerechte Konstruktion als auch durch eine besonders rationelle Herstellbarkeit auszeichnet.The invention has for its object to provide a suitable for rail vehicles articulated coupling, which is characterized both by a claim-appropriate design and by a particularly efficient manufacturability.

Zusammenfassung der ErfindungSummary of the invention

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Gelenkkupplung mit den Merkmalen des Anspruchs 1. Diese Gelenkkupplung weist eine in eine Kupplungsgabel eingreifende Kupplungslasche mit einem sphärischen Lager auf, wobei Kupplungsgabel und Kupplungslasche auch als Mutterteil bzw. Vaterteil bezeichnet werden. Teile des sphärischen Lagers sind ein Innenring mit einer konvexen Oberfläche und ein damit zusammenwirkender, eine Gleitlagerung bildender Außenring mit einer konkaven Oberfläche, welcher in einer Öffnung der Kupplungslasche befestigt ist. Zur Befestigung des Außenrings in der typischerweise kreisrunden Öffnung der Kupplungslasche weisen sowohl der Außenring als auch die Kupplungslasche jeweils eine Nut auf, wobei ein Klemmring in der Nut des Außenrings und zugleich in der Nut der Kupplungslasche einliegt. In der Regel ist der Klemmring als einstückiges Metallteil axial geschlitzt; alternativ können auch mehrere einzelne Klemmringsegmente verwendet werden.This object is achieved by an articulated coupling with the features of claim 1. This joint coupling has an engaging in a coupling fork coupling tab with a spherical bearing, said coupling fork and coupling tab are also referred to as a mother part or father part. Parts of the spherical bearing are an inner ring with a convex surface and a cooperating, a sliding bearing outer ring forming with a concave surface which is fixed in an opening of the coupling tab. For attachment of the outer ring in the typically circular opening of the coupling tab, both the outer ring and the coupling tab each have a groove, wherein a clamping ring rests in the groove of the outer ring and at the same time in the groove of the coupling tab. In general, the clamping ring is slotted axially as a one-piece metal part; Alternatively, several individual clamping ring segments can be used.

Die Befestigung des Außenrings in der Kupplungslasche mittels Klemmring hat zum einen den Vorteil einer einfachen Montage, zum anderen sind aufgrund des Entfalls von Schweißarbeiten keine Restriktionen hinsichtlich der Werkstoffe gegeben. Insbesondere ist ein gesprengter Außenring verwendbar. Eine im Vergleich zum Außenring sowie zur Kupplungslasche geringe Breite des Klemmrings ermöglicht eine großflächige Anlage des Außenrings in der Öffnung der Kupplungslasche und damit eine besonders gleichmäßige Krafteinleitung. Vorzugsweise beträgt die in Axialrichtung gemessene Breite des Klemmrings weniger als 15%, insbesondere weniger als 10%, der in derselben Richtung gemessenen Breite des Außenrings. Letztgenannte Breite stimmt vorzugsweise mit der Breite der Kupplungslasche überein.The attachment of the outer ring in the coupling tab by means of clamping ring on the one hand has the advantage of a simple installation, on the other hand, given no restrictions on the materials due to the elimination of welding. In particular, a blasted outer ring is usable. A small compared to the outer ring and the coupling tab width of the clamping ring allows large-scale investment of the outer ring in the opening of the coupling plate and thus a particularly uniform force application. Preferably, the width of the clamping ring measured in the axial direction is less than 15%, in particular less than 10%, of the width of the outer ring measured in the same direction. The latter width is preferably consistent with the width of the coupling tab.

In bevorzugter Ausgestaltung weist die Kupplungslasche Bohrungen auf, welche vom Umfang der Kupplungslasche zur Nut der Kupplungslasche reichen. Diese Bohrungen dienen der Aufnahme von Schrauben, mit denen die radiale Positionierung des Klemmrings zumindest abschnittsweise geändert werden kann. Hierbei kommt sowohl eine Vergrößerung als auch eine Verkleinerung des Radius des Klemmrings in Betracht. Bei größtmöglichem Radius befindet sich der einen Teil der Gelenkkupplung bildende Klemmring vorzugsweise vollständig in der Nut der Kupplungslasche. In vorteilhafter Weise ist der Klemmring derart elastisch vorgespannt, dass er, solange keine weiteren Kräfte auf ihn einwirken, vollständig in der Nut der Kupplungslasche einliegt. In dieser Positionierung des Klemmrings ist ein sehr einfaches Einsetzen des Außenrings in die Öffnung der Kupplungslasche möglich. Um anschließend den Klemmring formschlüssig mit dem Außenring zu verbinden, müssen lediglich die in den Bohrungen befindlichen Schrauben angezogen werden, die hierbei eine Kraft auf den Klemmring radial nach innen ausüben.In a preferred embodiment, the coupling tab has bores which extend from the circumference of the coupling tab to the groove of the coupling tab. These holes serve to receive screws with which the radial Positioning of the clamping ring can be changed at least in sections. In this case, both an increase and a reduction of the radius of the clamping ring come into consideration. With the greatest possible radius, the clamping ring forming part of the joint coupling is preferably located completely in the groove of the coupling lug. Advantageously, the clamping ring is elastically biased so that it rests completely in the groove of the coupling tab, as long as no further forces acting on him. In this positioning of the clamping ring a very simple insertion of the outer ring in the opening of the coupling tab is possible. In order subsequently to connect the clamping ring to the outer ring in a form-fitting manner, only the screws located in the bores have to be tightened, which in this case exert a force on the clamping ring radially inwards.

Bei der Demontage der Gelenkkupplung kann es in analoger Weise ausreichend sein, die genannten Schrauben zu lösen, damit der Klemmring expandiert und eine Trennung von Außenring und Kupplungslasche ermöglicht. Sollte der Klemmring, etwa aufgrund korrosiver Einwirkungen, in der Nut des Außenrings festsitzen, so ist in vorteilhafter Weise die Möglichkeit vorgesehen, den Klemmring mittels mehrerer Schrauben nach außen, in die Nut der Kupplungslasche, zu ziehen.When disassembling the universal joint, it may be sufficient in an analogous manner to solve the said screws, so that the clamping ring expands and allows separation of outer ring and coupling tab. If the clamping ring, for example, due to corrosive effects, stuck in the groove of the outer ring, it is advantageously provided the possibility to pull the clamping ring by means of several screws to the outside, in the groove of the coupling tab.

In Abwandlung von der vorstehend beschriebenen Anordnung der Schrauben, welche zur Verlagerung und / oder Sicherung des Klemmrings vorgesehen sind, kann auch eine stirnseitige Verschraubung des Klemmrings vorgesehen sein. Der Vorteil einer solchen Verschraubung mit Schrauben, welche parallel zur Axialrichtung des Klemmrings sowie des Außen- und Innenrings angeordnet sind, kann, abhängig von den geometrischen Gegebenheiten im Einzelfall, insbesondere in einer günstigen Spannungsverteilung liegen, wobei die Lage einer neutralen Faser ausgenutzt wird. Auch eine Kombination aus radialer und axialer Anordnung von Klemmschrauben, die direkt oder indirekt auf den Klemmring einwirken, ist möglich.In a modification of the above-described arrangement of the screws, which are provided for the displacement and / or securing of the clamping ring, an end-side screwing of the clamping ring can be provided. The advantage of such a screw with screws, which are arranged parallel to the axial direction of the clamping ring and the outer and inner ring can, depending on the geometric conditions in the individual case, in particular lie in a favorable stress distribution, the position of a neutral fiber is utilized. A combination of radial and axial arrangement of clamping screws, which act directly or indirectly on the clamping ring, is possible.

Die Schrauben, welche zum Eindrücken des Klemmrings in die Nut des Außenrings vorgesehen sind, können beispielsweise durch Verkleben gegen Losdrehen gesichert sein. Zusätzlich oder statt einer Verklebung ist als Sicherung gegen Herausdrehen der Schrauben vorzugsweise eine Schelle aus Stahl um die Öffnungen in der Kupplungslasche gelegt, wobei eine Befestigung auf einer oder symmetrisch auf beiden Seiten vorgesehen sein kann.The screws which are provided for pressing the clamping ring in the groove of the outer ring can be secured for example by gluing against loosening. In addition to or instead of gluing, a clip made of steel is preferably placed around the openings in the coupling tab as a safeguard against unscrewing of the screws, wherein an attachment on one or symmetrically on both sides can be provided.

Der Klemmring weist in vorteilhafter Ausgestaltung im Querschnitt eine radial nach innen gerichtete, mindestens einseitige Verjüngung auf. Vorzugsweise ist die Verjüngung zweiseitig, symmetrisch zu einer den Klemmring sowie ggf. die radialen Bohrungen schneidenden Ebene, ausgebildet. Die Nut im Außenring weist einen dem Querschnitt des Klemmrings angepassten, sich radial nach innen verjüngenden Querschnitt auf, so dass der Klemmring spielfrei im Außenring positionierbar ist. Dagegen bleibt bei komplett montierter Gelenkkupplung das Spiel des Klemmrings in der Nut der Kupplungslasche vorzugsweise bestehen.The clamping ring has in an advantageous embodiment in cross-section on a radially inwardly directed, at least one-sided taper. Preferably, the taper is bilaterally, symmetrically to a clamping ring and possibly the radial holes intersecting plane formed. The groove in the outer ring has a cross section of the clamping ring adapted, radially inwardly tapering cross section, so that the clamping ring is positionable in the outer ring without play. In contrast, the game of the clamping ring in the groove of the coupling tab preferably remains in completely assembled joint coupling.

Nach einer bevorzugten Weiterbildung sind zwei in parallelen Ebenen angeordnete Klemmringe zwischen dem Außenring und der Kupplungslasche positioniert. Abgesehen von den Nuten, welche die Klemmringe aufnehmen, können die äußere Oberfläche des Außenrings sowie die Oberfläche der Öffnung der Kupplungslasche durchgehend zylindrisch gestaltet sein. Die axiale Festlegung des Außenrings relativ zur Kupplungslasche erfolgt dabei ausschließlich über die Klemmringe. Abweichend von dieser Ausgestaltung ist es auch möglich, an der Kupplungslasche und / oder am Außenring einen Flansch auszubilden. In diesem Fall ist zwischen die Kupplungslasche und den Außenring vorzugsweise nur ein einziger Klemmring eingesetzt. Der Flansch der Kupplungslasche oder des Außenrings weist vorzugsweise eine abgeschrägte, am jeweils anderen Bauteil anschlagende Flanke auf. Die Stirnseite des an eines der Bauteile, insbesondere den Außenring, angeformten Flansches fluchtet vorzugsweise mit der stirnseitigen Oberfläche des anderen Bauteils, insbesondere der Kupplungslasche.According to a preferred refinement, two clamping rings arranged in parallel planes are positioned between the outer ring and the coupling lug. Apart from the grooves which receive the clamping rings, the outer surface of the outer ring and the surface of the opening of the coupling tab can be designed to be cylindrical throughout. The axial fixing of the outer ring relative to the coupling tab takes place exclusively via the clamping rings. Deviating from this embodiment, it is also possible to form a flange on the coupling tab and / or on the outer ring. In this case, preferably only a single clamping ring is inserted between the coupling tab and the outer ring. The flange of the coupling tab or the outer ring preferably has a bevelled, abutting on the other component edge. The end face of the integrally formed on one of the components, in particular the outer ring, flange is preferably aligned with the front surface of the other component, in particular the coupling tab.

Einander entsprechende oder gleichwirkende Teile sind in allen Figuren mit den gleichen Bezugszeichen gekennzeichnet.Corresponding or equivalent parts are identified in all figures with the same reference numerals.

In Figur 1 ist vereinfacht eine Gelenkkupplung 1 für Schienenfahrzeuge dargestellt, deren prinzipielle Funktion beispielsweise aus der DE 103 60 289 A1 bekannt ist. Ebenso eignet sich die Gelenkkupplung 1 beispielsweise für Kupplungen mit Zugstangen, wie in der DE 195 43 183 A1 beschrieben. Eine weitere Anwendung für die Gelenkkupplung 1 ist in der Kopplung von auf einem gemeinsamen Drehgestell abgestützten Enden zweier gelenkig miteinander verbundener Fahrzeugeinheiten, wie grundsätzlich in der EP 0 520 301 A1 beschrieben, gegeben.In FIG. 1 simplified is shown a joint coupling 1 for rail vehicles whose principal function, for example, from the DE 103 60 289 A1 is known. Likewise, the universal joint 1, for example, for couplings with tie rods, as in the DE 195 43 183 A1 described. Another application for the universal joint 1 is in the coupling of supported on a common bogie ends of two articulated vehicle units, as basically in the EP 0 520 301 A1 described, given.

Die Gelenkkupplung 1 weist ein sphärisches Lager 2 auf, mittels dessen eine Kupplungslasche 3 mit einer Kupplungsgabel 4 verbunden ist. Ein Spiel der Gelenkkupplung 1 in einer ersten Richtung ist mit x bezeichnet; des Weiteren existiert ein Spiel in einer hierzu orthogonalen Richtung. Je nach Einbaulage der Gelenkkupplung 1 kann es sich bei dem Spiel x um das vertikale Spiel oder das horizontale Spiel handeln.The universal joint 1 has a spherical bearing 2, by means of which a coupling tab 3 is connected to a coupling fork 4. A game of the universal joint 1 in a first direction is denoted by x; Furthermore, a game exists in a direction orthogonal thereto. Depending on the installation position of the universal joint 1, the game x may be the vertical game or the horizontal game.

Das Lager 2 ist als Gleitlager ausgebildet, wobei ein Innenring 5 mit einer kugeligen Oberfläche 6 in einem Außenring 7 mit einer konkaven Oberfläche 8 verschwenkbar gelagert ist. Der Innenring 5 ist durchdrungen von einem Bolzen 9, welcher in Bohrungen 10, die sich in Gabelwangen 11, 12 der Kupplungsgabel 4 befinden, gehalten ist. Die Bohrungen 10 sind, um ein Verschieben des Bolzens 9 zu verhindern, mit Verschlussklappen 13 abgedeckt.The bearing 2 is designed as a sliding bearing, wherein an inner ring 5 is pivotally mounted with a spherical surface 6 in an outer ring 7 with a concave surface 8. The inner ring 5 is penetrated by a pin 9, which is held in holes 10 which are located in fork cheeks 11, 12 of the clutch fork 4. The holes 10 are to prevent displacement of the bolt 9, covered with flaps 13.

Vor der Montage der Gelenkkupplung 1 wird der Außenring 7 durch in Radialrichtung wirkende Kräfte gesprengt. Dies hat den Vorteil, dass der Außenring 7 längs einer Ebene E, die eine normal zur Symmetrieachse A des sphärischen Lagers 2 angeordnete Symmetrieebene dieses Lagers 2 bildet, nicht geteilt zu sein braucht. Der als gesprengter Außenring aufgebaute Außenring 7 ist in eine zylindrische Öffnung 14 der Kupplungslasche 3 eingesetzt. Details der Befestigung des Außenrings 7 in der Öffnung 14 der Kupplungslasche 3 werden insbesondere anhand der Figuren 2 und 3 deutlich, die Ausführungsbeispiele von Gelenkkupplungen 1 zeigen, deren grundsätzlicher Aufbau dem Ausführungsbeispiel nach Figur 1 entspricht.Before assembly of the universal joint 1, the outer ring 7 is blown up by forces acting in the radial direction. This has the advantage that the outer ring 7 along a plane E, which forms a normal to the axis of symmetry A of the spherical bearing 2 arranged symmetry plane of this bearing 2 need not be divided. The constructed as a blasted outer ring outer ring 7 is inserted into a cylindrical opening 14 of the coupling plate 3. Details of the attachment of the outer ring 7 in the opening 14 of the coupling tab 3 are in particular with reference to the Figures 2 and 3 clearly, the embodiments of articulated couplings 1 show, the basic structure of the embodiment according to FIG. 1 equivalent.

Die nachfolgenden Ausführungen beziehen sich, soweit nicht anders erwähnt, auf alle dargestellten Ausführungsbeispiele. Eine Nut 17 an der äußeren, im Wesentlichen zylindrischen Oberfläche 16 des Außenrings 7 liegt einer Nut 15 in der Wandung 18 der Öffnung 14 gegenüber. Die übereinstimmende, in Axialrichtung gemessene Breite b der Nuten 15, 17 beträgt ca. 10% der Breite B der Kupplungslasche 3 sowie des Außenrings 7. Im dargestellten, fertig montierten Zustand der Gelenkkupplung 1 greift ein Klemmring 18 in beide Nuten 15, 17 ein und stellt damit eine Verbindung zwischen dem Außenring 7 und der Kupplungslasche 3 her. Bevor der Außenring 7 in die Öffnung 14 der Kupplungslasche 3 eingesetzt wird, befindet sich der Klemmring 18 aufgrund dessen elastischer Vorspannung vollständig innerhalb der Nut 15 in der Kupplungslasche 3.The following statements relate, unless otherwise stated, to all illustrated embodiments. A groove 17 on the outer, substantially cylindrical surface 16 of the outer ring 7 is opposite to a groove 15 in the wall 18 of the opening 14. The matching, measured in the axial direction width b of the grooves 15, 17 is about 10% of the width B of the coupling plate 3 and the outer ring 7. In the illustrated, fully assembled state of the universal joint 1, a clamping ring 18 engages in both grooves 15, 17 and thus provides a connection between the outer ring 7 and the coupling tab 3 ago. Before the outer ring 7 is inserted into the opening 14 of the coupling tab 3, the clamping ring 18 is due to the elastic bias completely within the groove 15 in the coupling tab. 3

In anhand der Figuren nicht erkennbarer Weise ist der Klemmring 18 axial geschlitzt, so dass der Durchmesser des Klemmrings 18 durch auf diesen einwirkende Kräfte variiert werden kann. Befindet sich der Außenring 7 während der Montage der Gelenkkupplung 1 relativ zur Kupplungslasche 3 in der endgültigen, dargestellten Position, so wird der Durchmesser des Klemmrings 18 mittels einzelner Schrauben 19, die jeweils eine in Radialrichtung angeordnete Bohrung 20 in der Kupplungslasche 3 durchdringen, verringert, so dass der Klemmring 18 teilweise in die Nut 17 des Außenrings 7 eingreift. Die Schrauben 19 sind durch eine Stahlschelle 21 gegen Herausdrehen gesichert. Die die Kupplungslasche 3 durchdringende Bohrung 20 ist als Gewindebohrung 22 ausgebildet, welche einen Durchmesser aufweist, der die konstante Breite b der Nut 15 der Kupplungslasche 3 etwas unterschreitet. Dagegen weist die Nut 17 des Außenrings 7 eine radial nach innen einseitig (Figur 3) bzw. zweiseitig (Figur 2) konisch verlaufende Form auf, die einer Verjüngung 23 des Klemmrings 18 angepasst ist. Damit ist der Klemmring 18 spielfrei in der Nut 17 verspannt.In the manner not apparent from the figures, the clamping ring 18 is slotted axially, so that the diameter of the clamping ring 18 can be varied by acting on these forces. Is the outer ring 7 during assembly of the universal joint 1 relative to the coupling tab 3 in the final position shown, the diameter of the clamping ring 18 by means of individual screws 19, each penetrating a radially arranged bore 20 in the coupling tab 3, reduced, so that the clamping ring 18 partially engages in the groove 17 of the outer ring 7. The screws 19 are secured by a steel clamp 21 against unscrewing. The coupling tab 3 penetrating bore 20 is formed as a threaded bore 22 which has a diameter which falls slightly below the constant width b of the groove 15 of the coupling tab 3. In contrast, the groove 17 of the outer ring 7 has a radially inwardly one-sided ( FIG. 3 ) or on two sides (Figure 2) conically extending shape, which is adapted to a taper 23 of the clamping ring 18. Thus, the clamping ring 18 is tensioned in the groove 17 without play.

Mit der beidseitig angeschrägten Form des Klemmrings 18 gemäß Figur 2 ist ein einziger Klemmring 18 ausreichend, während bei nur einseitiger Anschrägung des Klemmrings 18 gemäß Figur 3 vorzugsweise zwei Klemmringe 18 zwischen die Kupplungslasche 3 und den Außenring 7 gespannt sind. Insbesondere in Fällen, in denen nur ein einziger, einseitig angeschrägter Klemmring 18 vorhanden ist, ist es vorteilhaft, wenn an den Außenring 7, wie in Figur 3 sichtbar, ein Flansch 24 angeformt ist. Dieser weist eine abgeschrägte Flanke 25 auf, welche an der Kupplungslasche 3 anliegt. In allen Ausführungsbeispielen weisen, unabhängig von einem ggf. vorhandenen Flansch 24, welcher alternativ auch an die Kupplungslasche 3 angeformt sein kann, der Außenring 7 sowie die Kupplungslasche 3 eine übereinstimmende Breite B auf. Ein Schwenkwinkel des Bolzens 9 relativ zum Außenring 7 ist mit α angegeben.With the both sides bevelled shape of the clamping ring 18 according to FIG. 2 is a single clamping ring 18 is sufficient, while only one-sided bevel of the clamping ring 18 according to FIG. 3 preferably two clamping rings 18 are stretched between the coupling tab 3 and the outer ring 7. In particular, in cases where only a single, one-sided tapered clamping ring 18 is present, it is advantageous if the outer ring 7, as in FIG. 3 Visible, a flange 24 is formed. This has a chamfered edge 25 which bears against the coupling tab 3. In all embodiments have, regardless of a possibly existing flange 24, which may alternatively be integrally formed on the coupling tab 3, the outer ring 7 and the coupling tab 3 has a matching width B. A pivot angle of the bolt 9 relative to the outer ring 7 is indicated by α.
