Abstract
Description
Die Erfindung betrifft eine Zugeinrichtung für Schienenfahrzeuge, im wesentlichen bestehend aus einem mit einem Befestigungsflansch versehenen Gehäuse, einer darin einliegenden, in Zugrichtung abgestützten Feder sowie einem Verbindungsstück zum Verbinden der Feder mit einem Zughaken, der an seinem Schaft ein Auge zur Aufnahme eines mit dem Verbindungsstück zusammenwirkenden Bolzens aufweist.The invention relates to a pulling device for rail vehicles, consisting essentially of a housing provided with a mounting flange, an inserted therein, in the pulling direction supported spring and a connecting piece for connecting the spring with a pulling hook, which has an eye on its shaft for receiving a with the connecting piece cooperating bolt.
Eine Zugeinrichtung mit den vorgenannten Merkmalen ist aus dem Katalog R 61 der Ringfeder GmbH bekannt, siehe darin den für Lokomotiven bestimmten Typ 400 oder DE 2 943 053 A1. Bei dieser Zugeinrichtungtung ist der Bolzen derart integriert, daß für ein Auswechseln der Verschleißteile Zughaken und Bolzen die Einrichtung aus dem Schienenfahrzeug ausgebaut und zerlegt werden muß.A traction device with the aforementioned features is known from the catalog R 61 of Ringfeder GmbH, see therein the type 400 or
Der Erfindung liegt die Aufgabe zugrunde, eine Zugeinrichtung der gattungsgemäßen Art auf möglichst einfache Weise so zu gestalten, daß die Verschleißteile Zughaken und Bolzen leicht auszuwechseln sind, wobei die Zugeinrichtung mit dem Fahrzeug verbunden bleiben soll.The invention has for its object to design a traction device of the generic type in the simplest possible way so that the wear parts pull hook and bolt are easy to replace, the traction device should remain connected to the vehicle.
Diese Aufgabe wird durch die im Kennzeichenteil des Patentanspruchs 1 angegebenen Merkmale dadurch gelöst, daß der Bolzen hinter der Feder angeordnet und durch eine Öffnung an der Unterseite des Gehäuses ein- und auszubauen ist, wobei die Öffnung durch einen den Bolzen haltenden, am Gehäuse lösbar angebrachten Deckel verschlossen ist.This object is achieved by the features specified in the characterizing part of
Eine alternative erfindungsgemäße Lösung der zugrunde liegenden Aufgabe besteht nach dem Kennzeichenteil des Anspruchs 2 darin, daß die Feder etwa in ihrer Längsmitte einen den Bolzen umschließenden Ring enthält, wobei der Ring und das Gehäuse jeweils an ihrer Unterseite eine Öffnung für den Ein- und Ausbau des Bolzens (5) aufweisen, und die Öffnung des Gehäuses durch einen lösbar angebrachten Deckel verschlossen ist, der den Bolzen unter Zwischenschaltung eines in der Öffnung des Ringes angeordneten Füllstückes trägt.An alternative solution to the underlying object according to the invention consists in the fact that the spring contains approximately in its longitudinal center a ring surrounding the bolt, the ring and the housing each having an opening on the underside for the installation and removal of the Have bolt (5), and the opening of the housing is closed by a detachably attached cover which carries the bolt with the interposition of a filler arranged in the opening of the ring.
Um für die vorgenannte Zugeinrichtung eine einfach aufgebaute Verdrehsicherung zu schaffen, besteht eine Ausgestaltung der Erfindung darin, daß der innerhalb der Feder befindliche Ring mit einer nach innen weisenden Leiste versehen ist, die in eine Nut des Verbindungsstückes eingreift.In order to provide a simply constructed anti-rotation device for the aforementioned traction device, one embodiment of the invention is that the ring located within the spring is provided with an inwardly facing strip which engages in a groove of the connecting piece.
Im Hinblick auf eine zuverlässige Halterung des Deckels wird gemäß einer weiteren Ausführungsform der Erfindung vorgeschlagen, daß das Gehäuse mit zwei jeweils neben der Öffnung parallel zueinander angeordneten Stegen versehen ist, die jeweils ein Langloch für die Halterung eines Riegels aufweisen, wobei der Deckel auf dem Riegel ruht und mit diesem durch zumindest eine Schraube verbunden ist.With regard to a reliable mounting of the lid, it is proposed according to a further embodiment of the invention that the housing is provided with two webs which are each arranged parallel to one another next to the opening and each have an elongated hole for holding a latch, the lid on the latch rests and is connected to it by at least one screw.
Um den Zughaken im hinteren Bereich in Längsrichtung und auch umfänglich zu führen, wird nach einer nächsten Ausgestaltung der Erfindung das Auge des Zughakens oben und unten von jeweils einem mit dem Gehäuse fest verbundenen Halteblech umgriffen.In order to guide the pull hook in the rear region in the longitudinal direction and also circumferentially, according to a next embodiment of the invention, the eye of the pull hook is gripped at the top and bottom by a holding plate which is firmly connected to the housing.

Gemäß Fig. 1 ist der Bolzen 5 hinter der Feder 2 angeordnet. Er kann durch eine Öffnung 1b an der Unterseite des Gehäuses 1 ein- und ausgebaut werden. Dies ermöglicht ein leichtes Auswechseln der Verschleißteile Zughaken 4 und Bolzen 5, wobei die eigentliche Zugeinrichtung mit dem Fahrzeug verbunden bleibt. Die Öffnung 1b ist durch einen lösbar am Gehäuse 1 angebrachten Deckel 1c verschlossen, der den Bolzen 5 hält. Für diese Halterung des Deckels 1c - siehe auch Fig. 2 - ist das Gehäuse 1 mit zwei neben der Öffnung 1b parallel zueinander angeordneten Stegen 1d versehen. Jeder Steg 1d hat ein Langloch 1e. In diesen Langlöchern 1e ist ein Riegel 10 eingeschoben, auf dem der Deckel 1c ruht. Der Riegel 10 und der Deckel 1c sind durch Schrauben 10a miteinander verbunden, so daß der Riegel 10 über den in der Öffnung 1b des Gehäuses 1 einliegenden Deckel 1c fixiert ist.1, the
Wie aus Fig. 1 weiter ersichtlich, wird der Zughaken 4 im hinteren Bereich in Längsrichtung geführt und zugleich gegen Verdrehen gesichert. Dazu dienen zwei Haltebleche 1f, die mit dem Gehäuse 1 fest verbunden sind und das Auge 4b des Zughakens 4 oben bzw. unten umgreifen. Die Haltebleche 1f haben im übrigen jeweils eine dem Durchmesser des Bolzens 5 entsprechende etwa halbkreisförmige Ausnehmung, die aus der Schnittdarstellung nicht hervorgeht.As can also be seen from FIG. 1, the
In der Ausführung nach Fig. 3 enthält die Feder 2 etwa in ihrer Längsmitte einen Ring 6, der den Bolzen 5 umschließt. Der Ring 6 und das Gehäuse 1 weisen jeweils an ihrer Unterseite eine Öffnung 6b bzw. 1b für den Ein- und Ausbau des Bolzens 5 auf. Die Öffnung 1b des Gehäuses 1 ist wiederum durch einen lösbar angebrachten Deckel 1c verschlossen, beispielsweise in der Art gemäß Fig. 1 und 2 oder über einfache Befestigungsschrauben (nicht dargestellt). Der Deckel 1c trägt den Bolzen 5 unter Zwischenschaltung eines Füllstückes 6a, das in der Öffnung 6b des Ringes 6 angeordnet ist.3, the
Bei der Zugeinrichtung nach Fig. 3 verhindert eine Zughakenführung 11, die mit dem im Querschnitt rechteckförmigen Schaft 4a des Zughakens 4 zusammenwirkt, das Verdrehen des Zughakens 4. Wie aus Fig. 4 ersichtlich, hat der innerhalb der Feder 2 befindliche Ring 6 eine nach innen weisende Leiste 6c, die in eine Nut 3a des Verbindungsstückes 3 eingreift. Durch die beiden vorbeschriebenen Verdrehsicherungen wird erreicht, daß die Öffnung 1b des Gehäuses 1 und die Öffnung 6b des Ringes 6 in ihrer Lage übereinstimmen.In the pulling device according to FIG. 3, a
