Description
Die Erfindung betrifft eine Mittelpufferkupplung für ein Schienenfahrzeug, bestehend aus einem vertikal schwenkbar an einem Anlenkgehäuse des Schienenfahrzeugs angebrachten und an seinem freien Ende einen Kupplungskopf tragenden Kupplungsschaft und einer Vorrichtung zur-horizontalen Mittenrückstellung nach dem Oberbegriff des Anspruchs 1.The invention relates to a central buffer coupling for a rail vehicle, consisting from a vertically pivotable on an articulated housing of the rail vehicle attached and at its free end a coupling head carrying clutch shaft and a device for horizontal-horizontal restoring according to the preamble of claim 1.
Derartige Vorrichtungen zur Mittenrückstellung sind beispielsweise aus der DE 18 10 593 B2, der DE 24 19 184 A1, der DE 28 22 104 A1 oder der DE 24 45 460 A1 bekannt.Such devices for center reset, for example, from DE 18 10 593 B2, DE 24 19 184 A1, DE 28 22 104 A1 or DE 24 45 460 A1 known.
Die DE 18 10 593 B2 zeigt eine Vorrichtung zur horizontalen Mittenrückstellung für eine mittels eines Kupplungsschafts schwenkbar an einem Schienenfahrzeug angebrachte Mittelpufferkupplung mit einer die Schwenkbewegung des Kupplungsschafts um seine vertikale Schwenkachse mitmachende Führung. Symmetrisch zur Längsachse des Kupplungsschafts sind an Führungen schräge Druckflächen angeordnet. Federnde Druckeinrichtungen, die sich am Gehäuse für den Kupplungsschaft abstützen und die die horizontale Mittenrückstellung bewirken, weisen jeweils eine Rückstellfeder, ein von der Rückstellfeder beaufschlagtes mit einer der Druckflächen zusammenwirkendes, eine Rolle tragendes Druckübertragungsglied und ein die Bewegung des Druckübertragungsgliedes begrenzendes Anschlagglied auf, wobei jeder Druckfläche eine Druckeinrichtung zugeordnet ist.DE 18 10 593 B2 shows a device for horizontal center reset for a means of a coupling shaft pivotally mounted on a rail vehicle mounted central buffer coupling with a pivoting movement of the Coupling shaft around its vertical pivot axis mitmachende leadership. Symmetrical to the longitudinal axis of the coupling shaft are inclined to guides Arranged pressure surfaces. Springing pressure devices located on the housing support for the coupling shaft and the horizontal center reset cause each have a return spring, one acted upon by the return spring with one of the pressure surfaces cooperating, a roller bearing Pressure transmitting member and a movement of the pressure transmitting member limiting stop member, wherein each pressure surface a pressure device assigned.
Aus der DE 24 19 184 A1 ist eine weitere Vorrichtung zur horizontalen Mittenrückstellung einer Mittelpufferkupplung für Schienenfahrzeuge bekannt, bei der symmetrisch beiderseits der Kupplungsachse je eine Druckfeder angeordnet ist, die jeweils an einem in einem Gehäuse geführtes Gleitstück anliegt. Die Gleitstücke sind jeweils über eine zugehörige Stützrolle mit vertikaler Achse durch die Kraft der vorgespannten Druckfedern gegen eine die horizontale Schwenkbewegung des Kupplungsschaftes um die vertikale Schwenkachse der Mittelpufferkupplung mitmachende Führung angedrückt. Die Stützrollen bilden symmetrisch beiderseits der Kupplungsachse je ein in der Führung gelagertes Stützrollenpaar, dessen beide Stützrollen jeweils unterschiedliche Abstände von der Kuppelachse aufweisen, wobei die Achsen der Stützrollen auf einem zur vertikalen Schwenkachse der Mittelpufferkupplung konzentrischen Kreis liegen. In der Mittenstellung der Mittelpufferkupplung liegen die Stützrollen jedes Stützrollenpaares jeweils an einer Gleitfläche des in Draufsicht etwa dreieckförmigen Gleitstückes an, wobei an jedem Gleitstück ein Führungsschaft angeordnet ist, der das Gehäuse durchdringt und in diesem geführt ist. Im normalen Betrieb, d.h. auch beim Durchfahren von Kurven oder Weichen ist die Mittenstellvorrichtung ständig wirksam, so dass sich an den Gleitflächen der Gleitstücke, die durch die Druckfedern gegen die Stützrollen gedrückt werden, durch die Schwenkbewegung der Mittelpufferkupplung ein relativ großer Verschleiß ergibt. Ein Kuppeln in einer Kurve ist nur mit Schwierigkeiten oder gar nicht möglich, da hier die Rückstellkräfte der Druckfedern dem manuell bewirkten Ausschwenken der zu kuppelnden Mittelpufferkupplungen entgegenwirken.From DE 24 19 184 A1 is a further device for horizontal center reset a central buffer coupling for rail vehicles known in the a compression spring is arranged symmetrically on both sides of the coupling axis, which bears in each case on a guided in a housing slider. The sliders are each via an associated support roller with a vertical axis through the Force of the prestressed compression springs against a horizontal pivoting movement the coupling shaft about the vertical pivot axis of the central buffer coupling mitmachende leadership pressed down. The support rollers form symmetrical on both sides of the coupling axis depending on a support roller pair mounted in the guide, whose two support rollers each have different distances from the dome axis have, wherein the axes of the support rollers on a vertical pivot axis the central buffer coupling concentric circle lie. In the middle position The central buffer coupling are the support rollers of each support roller pair respectively on a sliding surface of the approximately triangular in plan view slider at, wherein on each slider a guide shaft is arranged, which is the housing penetrates and is guided in this. In normal operation, i. also when driving through curves or points, the centering device is constantly effective, so that at the sliding surfaces of the sliders, by the Compression springs are pressed against the support rollers, by the pivoting movement the central buffer coupling results in a relatively large wear.

Durch die DE 28 22 104 A1 ist allerdings eine Einrichtung bekannt geworden, die die Nachteile vorgenannter Vorrichtung dadurch löst, dass die Mittenrückstellung abschaltbar ausgebildet ist und, wenn eine Mittenrückstellung nicht erforderlich oder nicht erwünscht ist, ausgeschaltet wird. Dazu ist an den Führungsschäften der Gleitstücke jeweils ein doppelarmiger Schwenkhebel angelenkt, dessen einer Hebelarm direkt oder indirekt mit einem Hubzylinder verbunden ist und dessen anderer Hebelarm sich gegen das Gehäuse abstützt, wobei die Gleitstücke durch Verschwenken der Schwenkhebel mittels angesteuertem oder fernbetägigbarem Hubzylinder gegen die Kraft der Druckfedern in eine Lage bringbar sind, in der die Stützrollen bei einer horizontalen Schwenkbewegung des Kupplungsschaftes keine Berührung mit den Gleitstücken haben und der Kupplungsschaft damit unbelastet von der Druckfeder frei verschwenkbar ist.By DE 28 22 104 A1, however, a device has become known solves the disadvantages of the aforementioned device in that the center reset is formed switchable and, if a center reset is not required or not desired is turned off. This is on the management shafts the sliders each articulated a double-armed pivot lever, whose one lever arm is directly or indirectly connected to a lifting cylinder is and whose other lever arm is supported against the housing, wherein the sliders by pivoting the pivot lever by means of controlled or fernbetägigbarem lifting cylinder against the force of the springs in one Position can be brought, in the support rollers in a horizontal pivoting movement of the coupling shaft have no contact with the sliders and the coupling shaft so that unloaded from the compression spring is free to pivot.
Aus der DE 24 45 460 A1 ist eine Vorrichtung zur steuerbaren Mitlenrückstellung von Mittelpufferkupplungen bekannt, wobei sich ein mit der Kuppelstange wirkverbundener Nocken zwischen zwei Anschläge erstreckt, welche in der horizontalen Bahn des Nockens von pneumatisch, hydraulisch oder elektrisch wirkenden Betätigungsmitteln verschiebbar angeordnet sind, wobei in der einen Endstellung der Anschläge der volle horizontale Seitenausschlag der Kuppelstange zur Verfügung steht, wohingegen in der anderen Endstellung der Nocken zwischen den Anschlägen eingeklemmt und die Kuppelstange damit in der Mittenstellung fixiert ist. Durch diese Einrichtung wird erreicht, dass die Kuppelstange beim Fahren fest und weitgehend schwingungsfrei in Mittellage stehen bleibt, aber andererseits diese Blockierung der Mittenlage nicht durch das Aufbringen zu großer Auslenkkräfte im normalen Betrieb erkauft wird.From DE 24 45 460 A1 discloses a device for controllable Mitlenrückstellung known from central buffer couplings, with one with the coupling rod operatively connected cam extends between two stops, which in the horizontal path of the cam of pneumatic, hydraulic or electric acting actuating means are arranged displaceably, wherein in the one End position of the stops the full horizontal lateral deflection of the coupling rod is available, whereas in the other end position of the cam sandwiched between the attacks and the coupling rod thus in the Center position is fixed. Through this device is achieved that the coupling rod while driving firmly and largely free of vibration in the middle position remains, but on the other hand this blocking of the center position is not due to the application is bought at large deflection forces in normal operation.

Ein mit den Gelenkarmen verbundenes Verriegelungsteil ist als drehbar gelagerter Verriegelungsbolzen ausgebildet, der getrieblich mit einem am hinteren Gelenkarm abgestützten Antrieb verbunden ist. Der Antrieb weist ein zwischen Anschlägen frei bewegliches Antriebselement zum Verschwenken des vorderen Gelenkarms auf. Somit ist der vordere Gelenkarm mit dem Kupplungskopf motorisch ein- und auschwenkbar und zur Reduzierung des Gefährdungspotentials bei Nichtbenutzung hinter die stirnseitigen Fahrzeugbegrenzung bringbar.Furthermore, from DE 195 26 504 C1 is a central buffer coupling for rail vehicles known that a vehicle-side hinged and supported rear articulated arm as well as an articulated joint with a vertical hinge pin articulated front articulated arm having the coupling head wearing. A locking member connected to the articulated arms is rotatable mounted locking bolt, the geared with one at the rear Articulated arm supported drive is connected. The drive has an intermediate Stops freely movable drive element for pivoting the front articulated arm on. Thus, the front articulated arm is with the coupling head motor can be swiveled in and out and used to reduce the risk potential when not in use behind the frontal vehicle boundary brought.

Ähnlich zur Ausführung der zuvor diskutierten DE-A-28 22 104 erfolgt auch hier das Verschwenken des Kupplungsschafts über beidseitig am Kupplungsschaft angeordnete Schwenkhebel, die mittels eines pneumatischen Hubzylinders betätigt werden. In dieser Vorrichtung zur horizontalen Mittenrückstellung ist dabei vorgesehen, dass der Kupplungsschaft in jede Stellung des vorgesehenen horizontalen Schwenkbereichs positionierbar ist. Bei der aus dem Stand der Technik gemäß der US-A-34 84 000 bekannten Mittelpufferkupplung erfolgt das Verschwenken des Kupplungsschafts über beidseitig am Kupplungsschaft angeordnete Schwenkhebel, die mittels eines pneumatischen Hubzylinders betätigt werden.US-A-34 84 000 discloses a central buffer coupling with a device for horizontal center return of a coupling shaft.
