Der Erfindung liegt die Aufgabe zugrunde, einen Weichenendverschluß vorzuschlagen, der einfach herzustellen und möglichst wartungsarm ist.The invention has for its object to propose a switch end closure that is easy to manufacture and as low maintenance as possible.
Diese Aufgabe wird durch einen Weichenendverschluß mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a switch end closure with the features of claim 1.
Der Erfindung liegt der Gedanke zugrunde, daß das bei den Weichenverschlüssen in der Technik übliche Führungsstück, das an der Backenschiene festgeschraubt wird, vollständig entfallen kann, indem der Zungenkloben die Führung der Schieberstange übernimmt. Darüber hinaus bietet die Verwendung von Führungsrollen den Vorteil, daß durch die Linienberührung zwischen den Führungsrollen und der aufliegenden Schieberstange sowie durch die Drehbeweglichkeit der Führungsrolle die auftretende Reibung bei der Bewegung der Schieberstange beim Stellvorgang weitestgehend abgebaut ist und daher keine Wartungsarbeiten erforderlich sind. Zuletzt besitzt die vorgeschlagene Lösung den Vorteil, daß durch die direkt unter der Zungenschiene angeordnete Schieberstangenaufhängung möglicherweise auftretende Schwingungen oder Verbiegungen der Schieberstange keinen oder nur einen sehr geringen Einfluß auf die Funktionsfähigkeit des Weichenendverschlusses besitzen.The invention is based on the idea that the guide piece which is customary in technology in the point locks and which is screwed onto the stock rail can be completely dispensed with by the tongue block taking over the guidance of the slide rod. In addition, the use of guide rollers has the advantage that due to the line contact between the guide rollers and the overlying slide rod and due to the rotational mobility of the guide roller, the friction occurring during the movement of the slide rod during the actuating process is largely reduced and therefore no maintenance work is required. Finally, the proposed solution has the advantage that, due to the slide rod suspension arranged directly under the tongue rail, possibly occurring vibrations or bending of the slide rod have no or only a very slight influence on the functionality of the turnout end closure.
Vorteilhafte Ausführungsformen sind durch die übrigen Ansprüche gekennzeichnet.Advantageous embodiments are characterized by the remaining claims.
So ist nach einer bevorzugten Ausführungsform die Schieberstange zwischen Schenkeln des Zungenklobens geführt. Diese Ausführungsform besitzt den Vorteil, daß durch die auf beiden Seiten der Schieberstange befindlichen Wandungsteile des Zungenklobens auch auf beiden Seiten eine seitliche Führung der Schieberstange bewirkt wird.According to a preferred embodiment, the slide rod is guided between the legs of the tongue block. This embodiment has the advantage that a lateral guidance of the slide rod is also effected on both sides by the wall parts of the tongue block located on both sides of the slide rod.
Durch das Führen der Schieberstange auf korrosionsbeständigen, wartungsfreien Rollen wird die Reibung zwischen Schieberstange und den Führungsstücken deutlich verringert und es bedarf keiner Schmierung der Schieberstange im betreffenden Bereich. Hierdurch kann die regelmäßig anfallende Wartungsarbeit deutlich verringert werden. Des weiteren ist die Verschiebung der Schieberstange stets leichtgängig, so daß die zu deren Verschieben notwendigen Stellkräfte geringer sind. Deshalb kann schließlich die Leistung der Stellantriebe entsprechend geringer ausgelegt werden.By guiding the slide rod on corrosion-resistant, maintenance-free rollers, the friction between the slide rod and the guide pieces becomes clear reduced and no lubrication of the slide rod in the area in question is required. As a result, the regular maintenance work can be significantly reduced. Furthermore, the displacement of the slide rod is always smooth, so that the actuating forces required to move it are lower. Therefore, the performance of the actuators can ultimately be designed accordingly lower.
Nach einer vorteilhaften Ausführungsform sind dieAccording to an advantageous embodiment, the
Gleitkontaktflächen der Schieberstange im Bereich des Zungenklobens molybdänbeschichtet. Durch das Beschichten der Gleitkontaktflächen der Schieberstange entfällt auch in diesem Bereich ein manuelles Schmieren, wodurch sich die Wartungsarbeit am Weichenendverschluß weiter verringert.Sliding contact surfaces of the slide rod in the area of the tongue block are coated with molybdenum. By coating the sliding contact surfaces of the slide rod, manual lubrication is also eliminated in this area, which further reduces the maintenance work on the switch end closure.
Vorteilhafterweise sind auf der Schieberstange Druckstücke befestigbar, wobei die Druckstücke einseitig und in Einbaulage oben auf der Schieberstange angeordnet sind. Indem die Druckstücke lediglich einseitig auf der Schieberstange angeordnet sind, wird die Anzahl der zu montierenden Druckstücke halbiert. Eine Verringerung der Anzahl der Druckstücke stellt keinen Nachteil gegenüber den herkömmlichen Systemen dar, weil Versuche und Beobachtungen gezeigt haben, daß bei der Verwendung herkömmlicher Systeme in der Regel nur eines der auf beiden Seiten der Schieberstange angeordneten Druckstücke gegen den Zungenkloben stößt und somit die Stellkräfte vollständig überträgt. Die Anordnung der Druckstücke in Einbaulage oben auf der Schieberstange bietet den Vorteil, daß bei einer Verstellung oder Nachjustierung der Druckstücke auf der Schieberstange diese für den Weichenschlosser leicht zugänglich sind. Hierdurch werden die anfallenden Wartungsarbeiten vereinfacht.Advantageously, pressure pieces can be fastened on the slide rod, the pressure pieces being arranged on one side and in the installed position on top of the slide rod. Since the pressure pieces are only arranged on one side on the slide rod, the number of pressure pieces to be assembled is halved. A reduction in the number of pressure pieces is not a disadvantage compared to the conventional systems, because tests and observations have shown that when using conventional systems, usually only one of the pressure pieces arranged on both sides of the slide rod hits the tongue block and thus the actuating forces completely transfers. The arrangement of the pressure pieces in the installed position on the top of the slide rod has the advantage that when the pressure pieces on the slide rod are adjusted or readjusted, they are easily accessible to the switch mechanic. This simplifies the maintenance work involved.

eingreift, die parallel zur Längsachse der Zungenschiene orientiert ist. Der Vorteil einer Formfederverspannung liegt darin, daß ein problemloses Ein- und Ausschlagen der Formfeder möglich ist und zudem eine beidseitige Montage je nach Verschlußlage in der Weiche durchgeführt werden kann. Darüber hinaus ist eine Formfeder aus Metall keinem Verschleiß sowie in Kontakt mit dem Material des Zungenklobens keiner Kontaktkorrosion ausgesetzt, wodurch der Wartungsaufwand weiter verringert werden kann. Indem die Formfeder in eine nutförmige Vertiefung in dem Zungenkloben eingreift, läßt sich diese selbstsichernd fixieren, ohne daß es weiterer Sicherungseinrichtungen und somit weiterer Einzelteile im Weichenendverschluß bedarf.engages, which is oriented parallel to the longitudinal axis of the tongue rail. The advantage of a form spring tension is that the form spring can be driven in and out without problems and, in addition, can be installed on both sides depending on the locking position in the switch. In addition, a shaped spring made of metal is not subject to wear and contact corrosion with contact with the material of the tongue block, which further reduces the maintenance effort. By engaging the form spring in a groove-shaped recess in the tongue block, this can be fixed in a self-locking manner without the need for further securing devices and thus further individual parts in the switch end closure.

Nachfolgend wird die Erfindung rein beispielhaft anhand der beigefügten Figuren beschrieben, in denen:The invention is described below purely by way of example with reference to the attached figures, in which:
Fig. 1 eine Seitenansicht eines Teils des erfindungsgemäßen Weichenendverschlusses ist; undFig. 1 is a side view of part of the switch termination according to the invention; and
Fig. 2 eine Seitenansicht des Zungenklobens mit eingeschobener Schieberstange in Blickrichtung X in Fig. 1 ist.Fig. 2 is a side view of the tongue block with inserted slide rod in the viewing direction X in Fig. 1.
Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
In Fig. 1 ist ein Teil des Weichenendverschlusses 10 zur Bewegung und Fixierung von Eisenbahn-Weichenzungen dargestellt. Die Schieberstangenhälfte 12, die auf der in der Zeichenebene der Fig. 1 rechts dargestellten Seite mit einer weiteren Schieberstange fest verbunden ist, dient dazu, eine Zungenschiene 14 gezielt zu bewegen. Während die in Fig. 1 dargestellte Zungenschiene 14 fest gegen die Backenschiene 16 gedrückt wird, wird die in Fig. 1 nicht dargestellte, zweite Zungenschiene im Bereich der anderen Schieberstangenhälfe in einem definierten Abstand zur Backenschiene gehalten, wodurch
Baustahl geschmiedeten Bauteils die Lebensdauer erhöht werden.Structural steel forged component life can be increased.
Um die zwischen den Schenkeln 50 des Zungenklobens 18 geführte Schieberstange 12 zu lagern, wird diese auf Führungsrollen 30 aufgelegt, die jeweils zwischen den Schenkeln des Zungenklobens drehbar befestigt sind. Da in Fig. 1, wie oben erläutert wurde, nur ein Teil einer Schieberstangenhälfte abgebildet ist, ist in Fig. 1 nur eine der insgesamt zwei Führungsrollen 30 ersichtlich, auf denen die Schieberstange 12 gelagert ist. Die zweite Auflage geschieht ebenfalls auf einer Führungsrolle, deren zugehöriger Zungenkloben mit der zweiten Zungenschiene fest verbunden ist .In order to mount the slide rod 12 guided between the legs 50 of the tongue block 18, this is placed on guide rollers 30 which are each rotatably fastened between the legs of the tongue block. Since only part of a slide rod half is shown in FIG. 1, as explained above, only one of the two guide rollers 30 on which the slide rod 12 is mounted can be seen in FIG. 1. The second edition also takes place on a guide roller, the associated tongue block of which is firmly connected to the second tongue rail.
Beim Stellvorgang der Weiche wird die Schieberstange 12 axial, d.h. in Richtung der Längserstreckung, durch einen geeigneten Antrieb bewegt . Dieser Antrieb kann entweder separat mit der Schieberstange 12 verbunden sein, oder aber die Schieberstange ist über Gestänge mit einem oder mehreren Klammerverschlüssen verbunden und der oder die Klammerverschlüsse wie auch der Weichenendverschluß mittels eines gemeinsamen Antriebs betätigt. Beim Stellvorgang wird die Schieberstange 12 horizontal in Längsrichtung bewegt und an der Schieberstange befestigte Druckstücke 38 bewirken die gewünschte Spureinstellung.When the switch is set, the slide rod 12 is axially, i.e. in the direction of the longitudinal extension, moved by a suitable drive. This drive can either be connected separately to the slide rod 12, or the slide rod is connected to one or more clamp closures via linkage and the clamp closure or closures as well as the switch termination are actuated by means of a common drive. During the setting process, the slide rod 12 is moved horizontally in the longitudinal direction and pressure pieces 38 fastened to the slide rod bring about the desired track adjustment.
Das in Fig. 1 dargestellte Druckstück 38a ist in Kontakt mit dem Zungenkloben 18 und drückt somit die am Zungenkloben befestigte Zungenschiene 14 gegen die Backenschiene 16. Beim Stellvorgang wird einerseits der Zungenkloben relativ zur Backenschiene bewegt und somit die Zungenschiene in Richtung der Backenschiene bewegt und des weiteren nach Abschluß des Stellvorganges die Zungenschiene in festem Kontakt zur Backenschiene gehalten.The pressure piece 38a shown in Fig. 1 is in contact with the tongue block 18 and thus presses the tongue rail 14 attached to the tongue block against the stock rail 16. During the adjusting process, the tongue block is moved relative to the stock rail on the one hand and thus the tongue rail is moved in the direction of the stock rail and the further held the tongue rail in firm contact with the stock rail after completion of the adjustment process.

daß Fertigungstoleranzen sowie funktionsbedingte Verstellungen zwischen dem Zungenkloben und der Zungenschiene kraftvoll ausgeglichen werden können. Ein derartiges elastisches Element ist vorzugsweise eine aus Metall bestehende Formfeder, die in eine nutförmige Vertiefung in dem Zungenkloben eingreifen kann, wobei die nutförmige Vertiefung parallel zur Längsachse des Schienenfußes orientiert ist. Durch das Einrücken der Formfeder in die nutförmige Vertiefung im Zungenkloben läßt sich diese selbstsichernd fixieren, ohne daß es weiterer Sicherungseinrichtungen bedarf.that manufacturing tolerances and function-related adjustments between the tongue block and the tongue rail can be powerfully compensated. Such an elastic element is preferably a metal formed spring which can engage in a groove-shaped recess in the tongue block, the groove-shaped recess being oriented parallel to the longitudinal axis of the rail foot. By inserting the form spring into the groove-shaped recess in the tongue block, it can be fixed in a self-locking manner without the need for further securing devices.
Durch die Verwendung von stahlgeschmiedeten Einzelkomponenten aus mikrolegiertem Stahl kann der Verschleiß des erfindungsgemäßen Weichenendverschlusses verringert und die Lebensdauer der Bauteile erhöht werden. Aufgrund der weitgehenden Verwendung von Standardelementen der Deutschen Bahn AG lassen sich Einstell- und Justierarbeiten einfach und problemlos durchführen, da die hierfür benötigten Werkzeuge von den Weichenschlossern mitgeführt werden.By using steel-forged individual components made of micro-alloyed steel, the wear of the turnout end closure according to the invention can be reduced and the service life of the components can be increased. Due to the extensive use of standard elements from Deutsche Bahn AG, adjustment and adjustment work can be carried out easily and without any problems, since the tools required for this are carried by the turnout mechanics.
Im Unterschied zu herkömmlichen Systemen sind keine kastenförmigen Führungsstücke mehr erforderlich, die im Bereich des Weichenendverschlusses an der Backenschiene befestigt sind und bei den im Stand der Technik verwendetenIn contrast to conventional systems, box-shaped guide pieces are no longer required, which are fastened to the stock rail in the area of the switch end closure and are used in those used in the prior art
Systemalternativen jeweils der Führung und Lagerung der Schieberstange dienen. Darüber hinaus ist der erfindungsgemäße Weichenendverschluß in den in der Technik seit langem bekannten, kastenförmig ausgebildeten Gleisschwellen verwendbar, so daß er problemlos gegen bestehende, liegende Systeme ausgetauscht werden kann. Es sind keine neuen Bohrbilder an der Zungenschiene erforderlich. Die bereits bestehenden Bohrungen an der Backenschiene können problemlos ungenutzt verbleiben.System alternatives are used to guide and mount the slide rod. In addition, the turnout end closure according to the invention can be used in the box-shaped track sleepers which have long been known in the art, so that it can be exchanged for existing horizontal systems without problems. No new hole patterns are required on the tongue rail. The existing holes on the stock rail can easily remain unused.
Der wesentliche Aspekt des erfindungsgemäßen Weichenendverschlusses liegt darin, daß die Anzahl von Bauteilen verringert werden konnte. Hierdurch läßt sich der erfindungsgemäße Weichenendverschluß kostengünstiger herstellen und montieren. Darüber hinaus läßt sich trotz der Verringerung von Bauteilen die Funktion des Weichenendverschlusses verbessern, weil Schwingungen und Verbiegungen der Schieberstange aufgrund der engen örtlichen Nähe zwischen den Druckstücken und der Schieberstangenauflage nur einen geringen Einfluß auf die Funktion ausüben. Weitere Verbesserungen wie das Vorsehen von Druckstücken nur auf der Oberseite oder aber die in den Figuren nicht dargestellte Federverspannung zwischen Zungenschiene und Zungenkloben dienen weiterhin dazu, die Anzahl benötigter Bauteile zu verringern und den Wartungsaufwand des Weichenendverschlusses zu minimieren. The essential aspect of the switch termination according to the invention is that the number of components could be reduced. This allows the Manufacture and assemble switch end closure according to the invention more cost-effectively. In addition, despite the reduction in components, the function of the switch end closure can be improved because vibrations and bending of the slide rod have only a slight influence on the function due to the close local proximity between the pressure pieces and the slide rod support. Further improvements, such as the provision of thrust pieces only on the upper side, or the spring tension between the tongue rail and the tongue block (not shown in the figures) continue to serve to reduce the number of components required and to minimize the maintenance effort of the turnout end closure.
