Abstract
Description
Die Erfindung betrifft eine längenverstellbare Kupplungsstange für Mittelpufferkupplungen von Schienenfahrzeugen.The invention relates to a length-adjustable coupling rod for middle buffer couplings of rail vehicles.
Bei bekannten Mittelpufferkupplungen überragt der Kupplungskopf das Fahrzeugprofil stirnseitig.In known medium buffer clutches, the coupling head protrudes the vehicle profile on the front.
Der Einsatz von Mittelpufferkupplungen, deren Kupplungskopf und Kupplungsstange bei Nichtgebrauch hinter das stirnseitige Fahrzeugprofil verbringbar sind, kommen insbesondere für Schienenfahrzeuge in Betracht, die nicht auf eigenen Trassen verkehren, z. B. Straßenbahnfahrzeuge, um eine Gefährdung anderer Verkehrsteilnehmer durch den das Schienenfahrzeug stirnseitig überragenden Kupplungskopf zu vermeiden.The use of central buffer clutches, their coupling head and Coupling rod behind the front vehicle profile when not in use are bringable come especially for rail vehicles that do not run on their own routes, e.g. B. tram vehicles to endanger other road users due to the protruding end of the rail vehicle Avoid coupling head.
Aus der US-A- 4 049 129, der DE 32 13 697 A1 oder der DE 43 28 811 C1 sind Mittelpufferkupplungen bekannt, bei denen sich der Kupplungskopf bzw. der Kupplungskopf und ein Teil der Kupplungsstange in horizontaler Ebene innerhalb des stirnseitigen Umgrenzungsprofils verschwenken lassen.From US-A-4 049 129, DE 32 13 697 A1 or DE 43 28 811 C1 medium buffer couplings are known, in which the Coupling head or the coupling head and part of the coupling rod in a horizontal plane inside the front Have the boundary profile swiveled.
In der verschwenkten Lage sind bei den vorgenannten Anordnungen, die in der Kupplungsstange oder an der Abstützung angeordneten Energieverzehrelemente nicht mehr funktionsbereit. Bei einem Stoß muß die Stoßenergie durch andere Baugruppen und Elemente aufgenommen werden.In the pivoted position in the aforementioned arrangements, those arranged in the coupling rod or on the support Energy consumption elements no longer functional. At a Shock must the impact energy by other assemblies and elements be included.
Weiter sind längenverstellbare Kupplungen bekannt, die im entkuppelten Zustand unter den Fahrzeugkörper geschoben werden können.Length-adjustable couplings are also known, which are uncoupled Condition can be pushed under the vehicle body can.
Bei der DE-PS 914 980 ist eine Kupplungsstange mit Kupplungskopf relativ zum Wagenkasten ein- und ausschiebbar und in beiden Endstellungen verriegelbar. Um das Ein- und Ausschieben sowie das Verriegeln der Kupplungsstange leicht vernehmen zu können ist die Kupplungsstange am freien Ende mit einem durch sie hindurchgeführten Anschlagbolzen versehen und in einer Hülse verschiebbar, die zwei einander gegenüberliegende Längsschlitze zur Führung des Anschlagbolzens aufweist, welche an beiden Enden bajonettverschlußartig erweitert sind.In DE-PS 914 980 there is a coupling rod with coupling head Can be pushed in and out relative to the car body and in both end positions lockable. To push in and out as well as Locking the coupling rod is easy to hear the coupling rod at the free end with one passed through it Provided with stop bolts and slidable in a sleeve, the two opposite longitudinal slots for guidance of the stop bolt, which at both ends like a bayonet are expanded.
Bei den bekannten einschiebbaren Kupplungen gleitet die Kupplungsstange meist in einer Hülse, die zwischen Anlenkpunkt am Fahrzeug und Wagenende liegt. Die gesamte Länge der Kupplungsstange liegt also auch in eingefahrener Stellung zwischen Wagenende und Anlenkpunkt, so daß der Anlenkpunkt relativ weit vom Fahrzeugende gelegen ist. Da beim Durchfahren enger Kurven ein großer Schwenkbereich der Kupplungsstange vorgesehen werden muß, geht bei länger Kupplungsstange ein großer Raum am Wagenende für die Einbringung anderer Baugruppen verloren. Insbesondere bei Niederflurfahrzeugen steht der Einbauraum für ein derartig ausgebildete Verstelleinrichtung nicht zur Verfügung.In the known insertable couplings, the coupling rod slides usually in a sleeve that is between the pivot point on Vehicle and end of the car is lying. The entire length of the coupling rod is also in the retracted position between the end of the car and articulation point, so that the articulation point is relatively far from End of vehicle is located. Because when driving through tight curves large swivel range of the coupling rod must be provided, with a longer coupling rod there is a large space at the end of the car the introduction of other assemblies lost. Especially at Low-floor vehicles, the installation space for such a trained Adjustment device not available.
Der Erfindung liegt daher die Aufgabe zugrunde eine längenverstellbare Kupplungsstange zu schaffen, die wenig Einbautiefe beansprucht und auch in eingeschobener Stellung in die Kupplungsstange eingebaute Energieverzehrelemente funktionsbereit bereithält.The invention is therefore based on the object of adjustable length To create coupling rod that requires little installation depth and also in the inserted position in the coupling rod built-in energy consumption elements ready for operation has ready.

Abstützung 3. Der Steuerschlitten 15' verschwenkt dabei den
Riegel 9b gegen die Kraft der Feder 11 und bringt ihn außer Eingriff
zur Verriegelungsklaue 9a. Nach der vollständigen Entriegelung
kommt der Steuerschlitten 15' auf seinem Weg in Richtung
auf die hintere Abstützung 3 am Betätigungsschlitten 12'
zur Anlage und verschiebt diesen auf der Führungsstange 13 in
Richtung auf die hintere Abstützung 3. Die am Betätigungsschlitten
12' angelenkten Betätigungshebel 14 üben auf die Scherenelemente
5a, 5b eine Druckkraft im Sinne einer Spreizung der
Schere 5 aus. Durch die Spreizung der Schere 5 erfolgt über die
Anbindung an die Schere 4 über die Gelenke 8 auch eine Spreizung
der Schere 4 gegen die Kraft der Federn 19, wobei eine Längenverstellung
