Description

Die Erfindung betrifft eine Kupplungshalterung für ein Schienenfahrzeug mit einer an dem Schienenfahrzeug gelenkig befestigten Kupplungstange und einer mit der einen Kupplungsstange gelenkig verbundenen, weiteren Kupplungsstange, die an ihrem freien Ende mit einem am Schienenfahrzeug angebrachten, schwenkbaren Verriegelungsglied lösbar verbindbar ist.The invention relates to a coupling holder for a rail vehicle with a coupling rod articulated to the rail vehicle and with a coupling rod articulated to the other coupling rod, which at its free end is releasably connectable to a pivotable locking member attached to the rail vehicle.

Gattungsgemäße Kupplungsvorrichtungen für Fahrzeuge sind beispielsweise aus den Druckschriften DE 10 2015 202 146 A1 , DE 100 20 351 A1 , DE 197 57 621 A1 , DE 43 03 008 A1 , DE 14 55 232 A und DE 14 55 224 C bekannt.Generic coupling devices for vehicles are for example from the publications DE 10 2015 202 146 A1 . DE 100 20 351 A1 . DE 197 57 621 A1 . DE 43 03 008 A1 . DE 14 55 232 A and DE 14 55 224 C. known.

Aus der EP 1 129 920 A1 ist eine gelenkige Kupplungsstange für Schienenfahrzeuge mit einer Halterung bekannt, welche eine kompakte Ruhestellung ermöglicht.From the EP 1 129 920 A1 an articulated coupling rod for rail vehicles with a holder is known which enables a compact rest position.

Bei einer bekannten Kupplungshalterung dieser Art, wie sie vorwiegend bei Straßenbahnen eingesetzt wird, ist es üblich, dass die Kupplung über ein Gelenk eingeklappt und in eine Ruhestellung gebracht wird, wenn die Kupplung nicht gebraucht wird. In dieser Ruhestellung muss die Kupplung gehalten werden, damit sie bei einem Bremsvorgang nicht ungewollt ausklappt. Dazu wird die Kupplung beim Einklappen mit einem Verriegelungsglied lösbar verriegelt. Das Verriegelungsglied ist am Schienenfahrzeug gelagert, so dass es das freie Ende der Kupplung bei seinem Ausschwenken am Schienenfahrzeug hält. Schwierigkeiten bereitet die Zugänglichkeit des Verriegelungsgliedes, weil dieses durch verschärfte Vorschriften dadurch schwer zugänglich ist, dass Energieverzehrelemente vorgebaut sind; es muss eine manuelle Verriegelung bzw. Entriegelung direkt am Verriegelungsglied vorgenommen werden. Darüber hinaus befindet sich das Verriegelungselement im Bewegungsbereich der Kupplung.In a known clutch holder of this type, as is mainly used in trams, it is common for the clutch to be folded in via a joint and to be brought into a rest position when the clutch is not in use. The clutch must be held in this rest position so that it does not unintentionally fold out when braking. For this purpose, the coupling is releasably locked with a locking member when folded. The locking member is mounted on the rail vehicle so that it holds the free end of the coupling when it swings out on the rail vehicle. Difficulties are the accessibility of the locking member, because this is difficult to access due to stricter regulations in that energy dissipation elements are built in; manual locking or unlocking must be carried out directly on the locking element. In addition, the locking element is in the range of motion of the coupling.

Der Erfindung liegt die Aufgabe zugrunde, die Handhabung bei einer Kupplungshalterung der eingangs angegebenen Art erheblich benutzerfreundlicher als bisher zu gestalten.The invention has for its object to make the handling of a coupling bracket of the type specified considerably more user-friendly than before.

Zur Lösung dieser Aufgabe ist erfindungsgemäß das Verriegelungsglied schwenkbar und dieses Verriegelungsglied ist ein federbelastetes Schloss mit einem seitlichen Schlitz zur Aufnahme eines mit dem freien Ende der weiteren Kupplungsstange verbundenen Bolzens, wobei das federbelastete Schloss gegen eine Seite eines Anschlags geführt ist; an das federbelastete Schloss greift ein Bowdenzug an, unter dessen Wirkung das federbelastete Schloss bei Freigabe der einen Seite des Anschlags den Bolzen freigibt.To achieve this object, the locking member is pivotable according to the invention and this locking member is a spring-loaded lock with a lateral slot for receiving a bolt connected to the free end of the further coupling rod, the spring-loaded lock being guided against one side of a stop; a Bowden cable engages the spring-loaded lock, under whose action the spring-loaded lock releases the bolt when one side of the stop is released.

Vorteilhaft ist die erfindungsgemäße Kupplungshalterung vor allem insofern, als sie ein federbelastetes Schloss mit einem seitlichen Schlitz zur vereinfachten Arretierung des Bolzens am freien Ende der weiteren Kupplungsstange aufweist sowie durch den Bowdenzug, mit dessen Hilfe der Bolzen leicht entriegelbar ist. Mit dem Bowdenzug erfolgt also das Entriegeln der Kupplung ferngesteuert.The coupling bracket according to the invention is particularly advantageous in that it has a spring-loaded lock with a side slot for simplified locking of the bolt at the free end of the further coupling rod, as well as the Bowden cable, with the aid of which the bolt can be easily unlocked. With the Bowden cable, the clutch is unlocked remotely.

Zur besonders benutzerfreundlichen Handhabung der Kupplungshalterung ist es besonders vorteilhaft, wenn der seitliche Schlitz und der ihn aufnehmende Bolzen so abgestimmt konturiert sind, dass bei einer Betätigung des Bowdenzugs der Bolzen zum freien Ende des seitlichen Schlitzes nach vorn geschoben und freigegeben wird. Dabei erfolgt keine Verriegelung der Kupplung, wenn der Bowdenzug wieder losgelassen wird. Auf diese Weise lässt sich die Kupplung besonders leicht aufklappen und mit einem weiteren Schienenfahrzeug verbinden.For particularly user-friendly handling of the coupling bracket, it is particularly advantageous if the side slot and the bolt receiving it are contoured in such a way that when the Bowden cable is actuated, the bolt is pushed forward and released towards the free end of the side slot. The clutch is not locked when the Bowden cable is released. In this way, the coupling can be opened very easily and connected to another rail vehicle.

Ferner wird als vorteilhaft angesehen, wenn das federbelastete Schloss mit einem zu der weiteren Kupplungsstange hin schlank zulaufenden Öfnungsansatz versehen ist, über den der Bolzen in den seitlichen Schlitz durch vorüber gehendes Verschwenken des federbelasteten Schlosses einbringbar ist. Durch diese Ausgestaltung der erfindungsgemäßen Kupplungshalterung kann nämlich der Bolzen am freien Ende der weiteren Kupplungsstange beim Einklappen automatisch durch eine Rastfunktion im seitlichen Schlitz des Schlosses verriegelt werden.It is also considered to be advantageous if the spring-loaded lock is provided with an opening neck that tapers slimmer towards the further coupling rod, via which the bolt can be introduced into the lateral slot by temporarily pivoting the spring-loaded lock. This configuration of the clutch holder according to the invention namely the bolt at the free end of the further coupling rod can be automatically locked by a locking function in the side slot of the lock when folding.

Die erfindungsgemäße Kupplungshalterung gestattet in vorteilhafter Weise, dass das federbelastete Schloss scheibenartig flach auf einer flachen fahrzeugseitigen Halterung ausgeführt ist und der Bolzen relativ hoch aufbaut, so dass eine hohe Bewegungsfreiheit beim Einsatz der erfindungsgemäßen Kupplungshalterung gegeben ist.The clutch holder according to the invention advantageously allows the spring-loaded lock to be designed in a disk-like flat manner on a flat vehicle-side holder and to build up the bolt relatively high, so that there is a high degree of freedom of movement when using the clutch holder according to the invention.

Zur weiteren Erläuterung der Erfindung sind in

Fig. 1
ein Ausführungsbeispiel der erfindungsgemäße Kupplungshalterung in einer Gesamtansicht und in
Fig. 2
vergrößert eine Darstellung des federbelasteten Schlosses in einer Ansicht von oben
gezeigt.To further explain the invention are in
Fig. 1
an embodiment of the clutch holder according to the invention in an overall view and in
Fig. 2
enlarged view of the spring-loaded lock in a view from above
shown.

Wie Fig. 1 erkennen lässt, weist die dargestellte Kupplungshalterung 1 eine Kupplungsstange 2 auf, die in nicht näher gezeigter Weise gelenkig mit einem Teil 3 eines nicht weiter dargestellten Schienenfahrzeugs, insbesondere einer Straßenbahn, verbunden ist. Mit der einen Kupplungsstange 2 ist gelenkig eine weitere Kupplungsstange 4 verbunden, die an ihrem freien Ende 5 über ein Verbindungsglied 6 einen Bolzen 7 trägt (siehe auch Fig. 2).How Fig. 1 can be seen, the coupling bracket 1 shown has a coupling rod 2, which is articulated in a manner not shown with a part 3 of a rail vehicle, not shown, in particular a tram. With the one coupling rod 2, a further coupling rod 4 is connected in an articulated manner, which carries a bolt 7 at its free end 5 via a connecting member 6 (see also Fig. 2 ).

Der Bolzen 7 befindet sich in den Darstellungen nach den Figuren in einem seitlichen Schlitz 8 eines federbelasteten Schlosses 9, das um eine Drehachse 10 schwenkbar ist; die Drehachse 10 ist in einer Halterung 11 gelagert, die in nicht näher dargestellter Weise mit einem Teil des Schienenfahrzeugs verbunden ist. Das Schloss 9 ist mit einer Nase 12 versehen, an der ein Ende einer Zugfeder 13 angreift, wie Fig. 1 zeigt; es können aber auch zwei Zugfedern vorhanden sein, wie es aus Fig. 2 hervorgeht. An ihrem anderen Ende sind die Zugfedern 13 mit der Halterung 11 verbunden. Die Zugfedern 13 stellen die Federbelastung des Schlosses 9 dar. Im gezeigten Zustand ist das Schloss 9 durch die Federkraft der Zugfedern 13 mit einem Ansatz 14 gegen eine Seite 15 eines Anschlags 16 gedrückt, der ebenfalls an der Halterung 11 befestigt ist. Das Schloss 9 ist in dieser Position verriegelt.The bolt 7 is located in the representations according to the figures in a side slot 8 of a spring-loaded lock 9, which is pivotable about an axis of rotation 10; the axis of rotation 10 is mounted in a holder 11 which is connected in a manner not shown to a part of the rail vehicle. The lock 9 is provided with a nose 12 on which one end of a tension spring 13 engages, such as Fig. 1 shows; but there can also be two tension springs, such as it out Fig. 2 evident. At its other end, the tension springs 13 are connected to the holder 11. The tension springs 13 represent the spring loading of the lock 9. In the state shown, the lock 9 is pressed by the spring force of the tension springs 13 with a shoulder 14 against a side 15 of a stop 16, which is also fastened to the holder 11. The lock 9 is locked in this position.

An der Nase 12 greift außen auch ein Bowdenzug 17 an, der mittels Betätigung eines Handgriffs 18 an einer gut zugänglichen Stelle des Schienenfahrzeugs die Nase 12 entgegen der Wirkung der Zugfedern 13 spannt und dabei einen weiteren Ansatz 19 gegen die andere Seite 20 des Anschlags 16 führt, wodurch der eine Ansatz 14 von dem Anschlag 16 freikommt.On the outside of the nose 12 there is also a Bowden cable 17 which, by actuating a handle 18 at an easily accessible location of the rail vehicle, tensions the nose 12 against the action of the tension springs 13 and thereby leads a further extension 19 against the other side 20 of the stop 16 , whereby the one approach 14 is released from the stop 16.

Bei der Betätigung des Bowdenzugs 17 ist durch eine zwischen der Außenkontur des Bolzens 7 und der Innenkontur des seitlichen Schlitzes 8 des Schlosses 9 abgestimmte Konturierung dafür gesorgt, dass der Bolzen 7 zum freien Ende 21 des Schlitzes 8 nach vorn geschoben wird und dabei dem Zugriff durch eine Bedienungsperson frei zugänglich ist. Beim Entfernen des Bolzens 7 schwenkt das Schloss 9 wieder in die gezeigte Position zurück.When the Bowden cable 17 is actuated, a contouring that is coordinated between the outer contour of the bolt 7 and the inner contour of the lateral slot 8 of the lock 9 ensures that the bolt 7 is pushed forward to the free end 21 of the slot 8 and thereby access by an operator is freely accessible. When the bolt 7 is removed, the lock 9 pivots back into the position shown.

Soll nach dem Entkuppeln eines weiteren Schienenfahrzeugs der Bolzen 7 wieder in dem Schloss 9 verriegelt werden, dann lässt sich dies in einfacher Weise dadurch bewirken, dass der Bolzen 7 gegen eine Schräge 22 eines Öffnungsansatz 23 geführt wird, wobei das Schloss 9 im Uhrzeigersinne vorüber gehend verschwenkt wird, bis der Bolzen 7 in den seitlichen Schlitz 8 des Schlosses eingefallen ist.If, after the uncoupling of a further rail vehicle, the bolt 7 is to be locked again in the lock 9, this can be effected in a simple manner in that the bolt 7 is guided against a slope 22 of an opening extension 23, the lock 9 passing in a clockwise direction is pivoted until the bolt 7 has fallen into the side slot 8 of the lock.
