Abstract

In an automatic coupling for rail vehicles, in addition to the coupling bodies which produce the mechanical connection between two vehicles and have a locking system line couplings are provided which in the coupled state produce the connection of the air lines and the electrical lines. The closure components of the locking system of the automatic coupling are decoupled with the aid of an actuation device. The actuation device is simultaneously provided for releasing at least one of the electric couplings of the line coupling and preferably for indirectly or directly drawing back the same such that no damage to the longitudinal guide of the electric coupling is caused by the transverse movement which is forcibly brought about by the mechanical coupling after it has been unlocked. <IMAGE>

Description

Die Erfindung betrifft eine automatische Kupplung nach dem Gattungsbegriff des Patentanspruches 1.The invention relates to an automatic clutch according to the preamble of claim 1.

Automatische Kupplungen der in Rede stehenden Art ermöglichen das automatisierte Verbinden zweier Schienenfahrzeuge, wobei im gekuppelten Zustand zwei derartige Kupplungen eine starre Verbindung zwischen den Fahrzeugen herstellen. Das Konzept derartiger Kupplungen gestattet bei geringem Raumbedarf das automatische Mitkuppeln von Luftleitungen und elektrischen Leitungen.Automatic couplings of the type in question enable the automated connection of two rail vehicles, with two such couplings establishing a rigid connection between the vehicles in the coupled state. The concept of such couplings allows automatic coupling of air lines and electrical lines with little space requirement.

Die für die elektrischen Leitungen vorgesehenen Elektrokupplungen müssen im gekuppelten Zustand im allgemeinen bis über das sogenannte Kupplungszentrum der Kupplungskörper der automatischen Kupplungen vorfahren, vor allem bei Benutzung von Steckkontakten Bei Willison-Kupplungen liegt dieses Zentrum vor der Profilkontur der mechanischen Kupplung. Daher müßte eine Elektrokupplung die Relativbewegungen zwischen zwei Willison-Kupplungen beim Kuppeln in X-, Y- und Z-Richtung ausgleichen. Hierzu müßte sie gegenüber der Willison-Kupplung in allen Richtungen beweglich angeordnet sein und bräuchte zum gegenseitigen Zentrieren beim Kuppeln große Greiforgane.In the coupled state, the electrical couplings provided for the electrical lines must generally advance to the coupling body of the automatic couplings above the so-called coupling center, especially when using plug contacts. With Willison couplings, this center lies in front of the profile contour of the mechanical coupling. An electric clutch would therefore have to compensate for the relative movements between two Willison clutches when coupling in the X, Y and Z directions. To do this, it would have to be movable in all directions with respect to the Willison coupling and would require large gripping members for mutual centering when coupling.

Ein einfachere Lösung bietet sich an, wenn die Elektrokupplung erst nachträglich, d.h. nach Beendigung des mechanischen Kuppelns, gekuppelt wird. Sie bräuchte dann im wesentlichen, d.h. bis auf den Ausgleich gewisser Querspiele zwischen den mechanischen Kupplungen, nur in Längsrichtung bewegt zu werden.A simpler solution is available if the electric coupling is only retrofitted, i.e. after mechanical coupling is completed. You would then essentially need, i.e. Except for the compensation of certain transverse play between the mechanical couplings, only to be moved in the longitudinal direction.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, auf einfache Weise sicherzustellen, daß die Elektrokupplung vor dem mechanischen Entkuppeln so gelöst wird, daß durch die von der mechanischen Kupplung erzwungenen Querbewegungen die Längsführung der Elektrokupplung nicht beschädigt wird.Proceeding from this, the object of the invention is to ensure in a simple manner that the electrical coupling is released before the mechanical uncoupling so that the longitudinal guidance of the electrical coupling is not damaged by the transverse movements forced by the mechanical coupling.

Zur Lösung dieser Aufgabe wird vorgeschlagen, die Elektrokupplung gemäß den Merkmalen des Kennzeichnungsteils des Patentanspruches 1 mit der Betätigung des Riegelsystems der automatischen Kupplung funktionell zu kuppeln, derart, daß beim Entkuppeln der einen oder anderen Seite der mechanischen Kupplung mindestens eine der Elektrokupplungen gelöst wird und somit mit dem Gegenstück außer Eingriff kommt und Querbewegungen, die von der mechanischen Kupplung erzwungen werden, ohne Beschädigung ausführen kann. Im besonderen ist sichergestellt, daß die Längsführung der Elektrokupplung nicht beschädigt wird.To solve this problem, it is proposed to functionally couple the electric clutch according to the features of the characterizing part of claim 1 with the actuation of the locking system of the automatic clutch, in such a way that when one or the other side of the mechanical clutch is disengaged, at least one of the electric clutches is released and thus disengages from the counterpart and can perform transverse movements, which are forced by the mechanical coupling, without damage. In particular, it is ensured that the longitudinal guide of the electric coupling is not damaged.

Vorteilhafte Ausgestaltungen und Weiterbildungen sind in weiteren Patentansprüchen aufgeführt.Advantageous refinements and developments are listed in further patent claims.

Die Erfindung ist nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die einzige Zeichnung erläutert. Die Zeichnung zeigt in schematischer Weise zu beiden Seiten einer Kuppel ebene zweier Schienenfahrzeuge befindliche Elektrokupplungen, von welchen die in der Zeichnung rechts befindlich dargestellte durch eine mit der mechanischen Kupplung in Verbindung stehende Betätigungseinrichtung verbunden ist.The invention is explained below using an exemplary embodiment with reference to the single drawing. The drawing shows schematically on both sides of a dome plane two rail vehicles electric clutches, of which the one shown in the drawing on the right is connected by an actuating device connected to the mechanical coupling.

In der einzigen Zeichnung ist schematisch eine Elektrokupplung als Bestandteil einer automatischen Kupplung wiedergegeben. Bei derartigen automatischen Kupplungen kann es sich z.B. um eine automatische Zugkupplung oder um eine Mittelpuffer-Kupplung, z.B. der Willison-Bauart, handeln. Im gekuppelten Zustand bilden zwei (nicht dargestellte) automatische Kupplungen eine starre Verbindung zwischen den Fahrzeugen, wobei jede der automatischen Kupplungen in mehrere Aggregate unterteilt ist. Die Kupplungskörper der automatischen Kupplung stellen die mechanische Verbindung zwischen zwei Schienenfahrzeugen her, wobei jeweils ein im Kupplungskörper ausgebildetes Riegelsystem das Kupplungsprofil beim Kuppeln schließt oder zum Entkuppeln öffnet. Dem Kupplungskörper ist eine die Elektrokupplung umfassende Leitungskupplung zugeordnet, welche im gekuppelten Zustand die Verbindung den Luftleitungen und den elektrischen Leitungen herstellt. Im allgemeinen sind ferner horizontal und vertikal federnde Abstützungen für die Kupplungskörper vorgesehen, ferner Betätigungseinrichtungen, welche die Verschlußteile des Riegelsystems zum Zwecke des Entkuppelns oder für den Abstoßbetrieb betätigen.In the single drawing, an electric clutch is shown schematically as part of an automatic clutch. Such automatic clutches can e.g. an automatic train coupling or a middle buffer coupling, e.g. the Willison type. When coupled, two automatic clutches (not shown) form a rigid connection between the vehicles, each of the automatic clutches being divided into several units. The coupling bodies of the automatic coupling establish the mechanical connection between two rail vehicles, a locking system formed in the coupling body closing the coupling profile when coupling or opening for uncoupling. The coupling body is assigned a line coupling comprising the electrical coupling, which in the coupled state establishes the connection between the air lines and the electrical lines. In general, horizontally and vertically resilient supports for the coupling body are also provided, as well as actuating devices which actuate the locking parts of the locking system for the purpose of uncoupling or for repelling operation.

In der Zeichnung sind bezüglich einer zwischen zwei Schienenfahrzeugen verlaufenden Kuppelebene 1 einander gegenüberliegend befindliche Elektrokupplungen 3 wiedergegeben, von welchen der gemäß Darstellung rechts angeordneten Elektrokupplung eine Betätigungseinrichtung 5 zugeordnet ist. Die Betätigunmgseinrichtung 5 entspricht einer Anordnung der vorgenannten Art, mittels welcher ein Entriegeln der (nicht dargestellten) automatischen Kupplung bewerkstelligt wird.The drawing shows electric clutches 3 located opposite one another between a coupling plane 1 running between two rail vehicles, of which an actuating device 5 is assigned to the electric clutch arranged on the right as shown. The actuation device 5 corresponds to an arrangement of the aforementioned type, by means of which the automatic clutch (not shown) is unlocked.

Gemäß der Erfindung ist die Betätigungseinrichtung 5 mit ihrem Handhebel 7 auch zum Entkuppeln bzw. Lösen der Elektrokupplung 3 und zum Zurückziehen derselben vorgesehen. Die Elektrokupplung 3 ist also mit der eigentlichen Betätigung des Riegelsystems des (nicht dargestellten) Kupplungskörpers so gekuppelt, daß beim Entkuppeln mindestens eine der Elektrokupplungen (im dargestellten Ausführungsbeispiel die rechte Elektrokupplung) gelöst und mit dem Gegenstück außer Eingriff gebracht wird, so daß sie die erforderlichen relativen Querbewegungen, die von der mechanischen Kupplung erzwungen werden, ohne Beschädigung der Längsführungen und zugeordneter Bauteile ausführen kann.According to the invention, the actuating device 5 with its hand lever 7 is also provided for uncoupling or releasing the electrical coupling 3 and for pulling it back. The electric clutch 3 is thus coupled to the actual actuation of the locking system of the clutch body (not shown) in such a way that at least one of the electric clutches (shown in FIG Embodiment right electrical coupling) is released and disengaged from the counterpart so that it can perform the required relative transverse movements, which are forced by the mechanical coupling, without damaging the longitudinal guides and associated components.

Selbst wenn der Vortrieb der Elektrokupplung beispielsweise durch Belüftung eines Zylinders aus der Luftleitung erfolgt, würde auch dann eine Beschädigung vermieden werden, wenn vor dem mechanischen Entkuppeln vergessen wurde, die Lufthähne wieder zu schließen, um pneumatisch die Elektrokupplungen zurückfahren zu lassen.Even if the electric coupling is propelled, for example, by venting a cylinder from the air line, damage would also be avoided if it was forgotten to close the air cocks again before the mechanical uncoupling in order to allow the electrical couplings to move back pneumatically.

Im dargestellten Ausführungsbeispiel ist der Handhebel 7 über eine schematisch wiedergegebene mechanische Koppelvorrichtung 9 mit der Elektrokupplung 1 in Verbindung befindlich dargestellt. Der Begriff mechanische Koppelvorrichtung umfaßt jegliche Einrichtung, welche geeignet ist, die Verbindung, z.B. Steckkontaktverbindung und ggfs. Verriegelung der beiden Elektrokupplungen zu lösen und wenigstens eine der Elektrokupplungen mittelbar oder unmittelbar in vorgenannter Weise aus dem Schwenkbereich der zugehörigen mechanischen Kupplung zurückzuziehen. Als mechanische Koppelvorrichtung sind auch mit pneumatischer Unterstützung wirkende Betätigungselemente gemeint, welche an den Elektrokupplungen angreifen und diese nach Entkupplung verlagern.In the exemplary embodiment shown, the hand lever 7 is shown connected to the electric clutch 1 via a schematically represented mechanical coupling device 9. The term mechanical coupling device encompasses any device which is suitable for releasing the connection, for example a plug contact connection and possibly locking the two electrical couplings, and for withdrawing at least one of the electrical couplings indirectly or directly in the aforementioned manner from the pivoting range of the associated mechanical coupling. Acting elements acting with pneumatic support, which act on the electrical couplings and displace them after disconnection, are also meant as a mechanical coupling device.
