Description

Die Erfindung betrifft eine Schnell-Lösevorrichtung für Kurz­kupplungen von Schienenfahrzeugen, bei denen das Kupplungs­verschlusstück an einem Winkelhebel angeordnet ist, durch welchen die zu kuppelnden Kupplungen miteinander verspannt werden, indem eine Verspannelement, wie Schraube, Exzenter etc. den Winkelhebel in Verspannrichtung beaufschlagt.The invention relates to a quick-release device for close couplings of rail vehicles, in which the coupling closure piece is arranged on an angle lever, by means of which the couplings to be coupled are clamped together by a clamping element, such as a screw, eccentric, etc., acting on the angle lever in the clamping direction.

Kurzkupplungen werden derzeit insbesondere deswegen bevorzugt verwendet, weil sich damit Zugverbände aufbauen lassen, die einerseits nicht dauernd wieder aufgelöst werden müssen und die andererseits den Abstand zwischen zwei gekuppelten Wagen so kurz wie möglich halten. Der Nachteil dieser bekannten Kurzkupplungen liegt darin, dass insbesondere in gefährlichen Situationen keine schnelle Lösung der Kurzkupplungen möglich ist, sondern durch meist umständliches und zeitraubendes Auf­schrauben eine zugrosse Zeitspanne für das Aufschrauben und damit Auflösen des Zugverbandes im Gefahrenfalle vergeht.Short couplings are currently preferred in particular because they can be used to build train assemblies that on the one hand do not have to be permanently removed and on the other hand keep the distance between two coupled carriages as short as possible. The disadvantage of these known close couplings lies in the fact that, particularly in dangerous situations, a quick release of the close couplings is not possible, but rather a time-consuming period of time for unscrewing and thus dissolving the train assembly in the event of danger due to mostly laborious and time-consuming screwing on.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die Nachteile der bekannten Kurzkupplungen zu vermeiden und eine Vorrichtung zu schaffen, mit der im Gefahrenfalle eine Kurzkupplung in kürzester Zeit gelöst werden kann.The present invention is therefore based on the object of avoiding the disadvantages of the known short couplings and of creating a device with which a short coupling can be released in the shortest possible time in the event of danger.

Die Lösung der Aufgabe besteht darin, dass einerseits am Kupplungskörper eine Brücke in Wirkrichtung des Verspann­elements verschwenkbar angeordnet ist und dass andererseits an der Brücke ein Riegel angeordnet ist, welcher hinter eine Riegelnase greift, welche an einem um einen Bolzen schwenk­baren Riegelscheibe angeordnet ist.The solution to the problem is that, on the one hand, a bridge is pivotably arranged in the direction of action of the tensioning element on the coupling body and, on the other hand, a bolt is arranged on the bridge, which engages behind a bolt nose which is arranged on a bolt disc that can be pivoted about a bolt.

Vorteilhaft wird die Riegelscheibe direkt oder über Zwischen­hebel von einem Betätigungszylinder bzw. von einer Fernbe­ dienungsvorrichtung, wie Bowdenzug, Kugelzug, Flexballzug verschwenkt wird.The locking disc is advantageous directly or via an intermediate lever from an actuating cylinder or from a Fernbe service device, such as Bowden cable, ball cable, flex ball cable is pivoted.

Zweckmässig trägt die Riegelscheibe eine Nase, welche sich an die Riegelscheibe der Gegenkupplung anlegt und diese verschwenkt.The locking disk expediently carries a nose, which rests against the locking disk of the counter coupling and pivots it.

Der Vorteil dieser Lösevorrichtung liegt vor allem darin, dass damit die zwei Wagen verbindende Kurzkupplung sofort und mit grösster Schnelligkeit entkuppelt werden kann.The main advantage of this release device is that it enables the short coupling connecting the two carriages to be uncoupled immediately and with the greatest speed.

In den Zeichnungen ist eine beispielsweise Ausführungsform der Erfindung dargestellt und zwar zeigt :

  • Figur 1 eine Seitenansicht eines gekuppelten Kupplungspaars
  • Figur 2 eine Draufsicht auf dieses Kupplungspaar.
An exemplary embodiment of the invention is shown in the drawings and shows:
  • Figure 1 is a side view of a coupled coupling pair
  • Figure 2 is a plan view of this coupling pair.

Nach den Figuren 1 und 2 trägt der Kuppelkopf 11 einen um den Bolzen 12 drehbaren Winkelhebel 13, an dessen kürzerem Hebelarm das Kupplungsverschlusstück 14 angelenkt ist, das seinerseits hinter einen Anschlag 15 der Gegenkupplung 16 greift, wodurch die beiden Kupplungen 11 und 16 miteinander verspannt werden, wenn der Winkelhebel 13 von der Schraube 17 als Verspannelement beaufschlagt wird. Am Kupplungsverschluss­stück 14 ist eine Zugfeder 18 so angebracht, dass das Ver­schlusstück 14 in Offenstellung verschwenkt wird, wenn keine Kräfte mehr auf das Verschlusstück 14 einwirken und das verschlusstück 14 in einer Raste 19 der Gegenkupplung 16 festgehalten wird. Die Verspannschraube 17 ist etwa in der Mitte einer Brücke 20 angeordnet, die ihrerseits an einer unteren Seite mit einem Bolzen 21 abklappbar an der Kupplung 11 angelenkt ist. Die Verschwenkung der Brücke 20 verläuft in Wirkrichtung der Verspannschraube 17. Am anderen, oberen Ende der Brücke 20 ist ein Riegel 22 angeordnet, dessen Riegelnase 23 hinter die Riegelnase 24 einer Riegelscheibe 25 greift, wenn die Kupplung sich in Normalstellung befindet.According to FIGS. 1 and 2, the coupling head 11 carries an angle lever 13 which can be rotated about the bolt 12, on the shorter lever arm of which the coupling locking piece 14 is articulated, which in turn engages behind a stop 15 of the counter coupling 16, as a result of which the two couplings 11 and 16 are clamped together when the angle lever 13 is acted upon by the screw 17 as a bracing element. A tension spring 18 is attached to the coupling closure piece 14 in such a way that the closure piece 14 is pivoted in the open position when no more forces act on the closure piece 14 and the closure piece 14 is held in a catch 19 of the counter-coupling 16. The bracing screw 17 is arranged approximately in the middle of a bridge 20, which in turn is hinged to the coupling 11 on a lower side with a bolt 21. The pivoting of the bridge 20 runs in the effective direction of the bracing screw 17. At the other, upper end of the bridge 20, a bolt 22 is arranged, the locking lug 23 engages behind the locking lug 24 of a locking disk 25 when the coupling is in the normal position.

Die Riegelscheibe 25 ist um einen Bolzen 26 verschwenkbar am Kuppelkopf 11 angeordnet und erstreckt sich mit einer Nase 27 bis in die Kuppelebene 28. Auf der anderen Seite der Riegelscheibe 25 erstreckt sie sich ebenfalls mit dem Teil 29 bis in die Kuppelebene 28. An der von der Riegelnase 24 abgewandten Seite der Riegelscheibe 25 ist an der Bohrung 30 ein Betätigungszylinder direkt oder über eine Fernbedienung angeschlossen, womit die Riegelscheibe 25 um den Bolzen 26 gedreht werden kann, wobei die Verschwenkung durch einen in einem Schlitz 31 liegenden Bolzen 32 begrenzt ist. Mit einer Zugfeder 33 wird die Riegelscheibe 25 in bekannter Art und Weise in der in der Zeichnung dargestellten Verschlusstellung gehalten. Eine weitere Feder 34 drückt gegen die Brücke 20.The locking plate 25 is pivotally mounted about a bolt 26 on the dome head 11 and extends with a nose 27 into the dome plane 28. On the other side of the locking plate 25, it also extends with the part 29 into the dome level 28 the locking lug 24 side of the locking plate 25 is connected to the bore 30, an actuating cylinder directly or via a remote control, with which the locking plate 25 can be rotated about the bolt 26, the pivoting being limited by a bolt 32 located in a slot 31. With a tension spring 33, the locking disk 25 is held in a known manner in the closed position shown in the drawing. Another spring 34 presses against the bridge 20.

Bei der Benutzung der erfindungsgemässen Vorrichtung ist von der in den Zeichnungen dargestellten Grundstellung auszugehen, in der die beiden Kupplungen 11 und 16 mit den Kupplungsver­schlusstücken 14 dadurch miteinander verspannt sind, dass der Winkelhebel 13 von der Spannschraube 17 so verdreht wird, dass das Verschlusstück 14 die Gegenkupplung 16 fest an die Kupplung 11 heranzieht. Die Verspannschraube 17 ist mit einer Kontermutter gesichert. In dieser Stellung greift die Riegel­nase 23 des an der Brücke 20 angeordneten Riegels 22 hinter die Riegelnase 24 der Riegelscheibe 25. Da so alle Teile mit­einander verspannt sind, sind auch die beiden Kupplungen 11 und 16 fest miteinander verbunden.When using the device according to the invention, it is to be assumed that the basic position shown in the drawings, in which the two clutches 11 and 16 are clamped together with the coupling closure pieces 14 in such a way that the angle lever 13 is rotated by the tensioning screw 17 in such a way that the closure piece 14 Counter clutch 16 pulls firmly onto the clutch 11. The bracing screw 17 is secured with a lock nut. In this position, the locking lug 23 of the locking bar 22 arranged on the bridge 20 engages behind the locking lug 24 of the locking disk 25. Since all parts are clamped together, the two couplings 11 and 16 are also firmly connected to one another.

Um die Schnellösung der beiden Kupplungen 11 und 16 zu be­wirken, wird die Riegelscheibe 25 mit der (nicht dargestellten) Betätigungsvorrichtung, welche an der Bohrung 30 angreift, verschwenkt um den Bolzen 26. Dabei passieren zwei Dinge gleichzeitig . Einmal gibt die verschwenkte Riegelscheibe 25 die Riegelnase 23 frei, sodass sich die Brücke 20 um den Bolzen 21 verschwenken kann, sodass die Verspannschraube 17 nicht mehr auf den Winkelhebel 13 drückt, wodurch das Kupplungsverschlusstück 14 frei kommt und aus der Rast 19 von der Feder 18 herausgedreht wird. Eine Feder 34 unterstützt die Schwenkbewegung der Brücke 20 in Offenstellung. Zum anderen drückt bei einer Drehung der Riegelscheibe 25 um den Bolzen 26 die Nase 27 der Riegelscheibe gegen den Teil 29 der Riegelscheibe 25 der Gegenkupplung, wodurch deren Riegelscheibe ebenfalls verschwenkt wird und die Öffnung der Gegenkupplung in der gleichen Weise wie bei der darge­stellten Kupplung in die Wege leitet. Mit den Federn 18 und 34 werden alle Kupplungsteile automatisch in Offenstellung verschwenkt, wenn die Riegelscheibe 25 in Öffnungsstellung verschwenkt wird. Die Feder 33 drückt die Riegelscheibe 25 wieder in die in der Zeichnung dargestellte Ruhestellung, sobald die Einwirkung der Betätigungselemente aufhört, sodass dann zum Schliessen der Kupplung die Brücke 20 so verschwenkt wird, dass die Riegelnase 23 hinter die Riegelnase 24 der Riegelscheibe 25 einfallen kann. Dann kann auch wieder die Verspannschraube 17 verschraubt werden, um den Winkelhebel 13 zu verdrehen, womit das Kupplungsverschlusstück 14 die Gegenkupplung 16 mit der Kupplung 11 verspannt. Dieselbe Manipulation muss mit der Brücke, der Verspannschraube etc. der Gegenkupplung vorgenommen werden.In order to bring about the quick release of the two clutches 11 and 16, the locking disk 25 is pivoted about the bolt 26 with the actuating device (not shown) which engages the bore 30. Two things happen at the same time. Once the pivoted locking plate 25 releases the locking lug 23, so that the bridge 20 can pivot about the bolt 21, so that the bracing screw 17 no longer presses on the angle lever 13, which means that Coupling closure piece 14 comes free and is rotated out of the catch 19 by the spring 18. A spring 34 supports the pivoting movement of the bridge 20 in the open position. On the other hand, when the locking disk 25 is rotated about the bolt 26, the nose 27 of the locking disk presses against the part 29 of the locking disk 25 of the counter-coupling, whereby its locking disk is also pivoted and the opening of the counter-coupling in the same manner as in the coupling shown Leads. With the springs 18 and 34, all coupling parts are automatically pivoted into the open position when the locking disk 25 is pivoted into the open position. The spring 33 presses the locking plate 25 back into the rest position shown in the drawing as soon as the action of the actuating elements ceases, so that the bridge 20 is then pivoted to close the coupling so that the locking lug 23 can engage behind the locking lug 24 of the locking plate 25. Then the bracing screw 17 can also be screwed again in order to turn the angle lever 13, whereby the coupling closure piece 14 braces the counter-coupling 16 with the coupling 11. The same manipulation must be carried out with the bridge, the bracing screw etc. of the counter coupling.

Es ist aber wichtig daraufhinzuweisen, dass beim schnellen Öffnen beide Kupplungen auch dann geöffnet werden, wenn nur die Riegelscheibe 25 einer Kupplung verschwenkt wird, solange dafür gesorgt wird, dass die Nasen 27 der Riegelscheiben 25 beider Kupplungen am jeweiligen Teil 29 der Gegenkupplungen anliegen. Dabei ist es nicht unbedingt notwendig, dass sich die Nase 27 und das Teil 29 in der Kupplungsebene 28 befindet, sondern es genügt, dass sich die Riegelscheibe der einen Kupplung von der Riegelscheibe der anderen Kupplung soweit verdrehen lässt, dass die Riegelnase 23 des Riegels 22 freigegeben wird.However, it is important to point out that, when opening quickly, both clutches are opened even if only the locking disk 25 of a coupling is pivoted, as long as it is ensured that the lugs 27 of the locking disks 25 of both clutches rest on the respective part 29 of the counter-couplings. It is not absolutely necessary for the nose 27 and the part 29 to be located in the coupling plane 28, but it is sufficient that the locking disk of the one coupling can be rotated by the locking disk of the other coupling to such an extent that the locking tab 23 of the locking bar 22 is released.
