- Fig. 8 It can be seen that two different sized angle guide plates 5 and 5 'can be used to realize different head webs 23 and 24 respectively, which makes it possible to use different rails 2 and 2' (see FIG. FIGS. 1 and 2 ), with otherwise identical components of the rail fastening system 1.
- the wider track rail angle guide plate 5 (eg, the UIC60 rail type) has a narrower head land 23 than that for a narrower rail foot (eg, the U50 rail type) which defines the angle guide plate 5 on its side toward the rail. Accordingly, the angle guide plate is thus seen slightly shorter in the direction of the rail.
- a narrower head bridge 23 is present and for a narrower rail foot (U50) according to a wider head restraint 24th

Description
Die Erfindung betrifft ein Schienenbefestigungssystem zur kraftschlüssig-elastischen Befestigung einer Schiene auf einer Schwelle einer Gleisanlage, umfassend mindestens eine an der Schwelle mit mindestens einem Befestigungselement festlegbare Winkelführungsplatte und mindestens eine Spannklemme, wobei die Spannklemme im endmontierten Zustand des Schienenbefestigungssystems mit mindestens einem Abschnitt auf den Schienenfuß drückt und so die Schiene auf der Schwelle festlegt, und wobei zwischen dem mindestens einen Abschnitt der Spannklemme und dem Schienenfuß ein Isolationselement angeordnet ist.The invention relates to a rail fastening system for frictional-elastic fastening of a rail on a threshold of a track system, comprising at least one fixable at the threshold with at least one fastener angle guide plate and at least one tensioning clamp, wherein the tensioning clamp in the final assembled state of the rail fastening system with at least a portion of the rail presses and so sets the rail on the threshold, and wherein between the at least one portion of the tension clamp and the rail foot an insulation element is arranged.

Aus der
An ein gattungsgemäßes Schienenbefestigungssystem stellen sich dabei verschiedene Aufgaben:
- Zunächst ist es wünschenswert, dass verschiedene Schienentypen (beispielsweise des Typs U 50 und des Typs UIC 60) mit unterschiedlichen Schienenfußbreiten auf unterschiedlichen Betonschwellentypen mit nur einem Spannklemmtyp verspannt werden können. Die Anpassung kann dabei über verschiedene Winkelführungsplatten erfolgen.
- First of all, it is desirable that different types of rails (for example of type U 50 and of type UIC 60) with different rail foot widths can be braced on different concrete sleeper types with only one tension clamp type. The adjustment can be done via different angle guide plates.
Dann ist es für eine einfache, kostengünstige und sichere Montage des Schienenbefestigungssystems vorteilhaft, wenn die Montage durch Verschiebung der Spannklemme von einer Vormontageposition (mit einer Verspannung der Schraube mit einem Drehmoment von ca. 50 Nm) in die Endmontageposition erfolgen kann. Hierbei ist es wichtig, dass ein einfaches Schieben der Spannklemme mittels eines Schiebers ohne vorheriges Lösen der (mit dem genannten Drehmoment vorgespannten) Schraube erfolgen kann. Wichtig ist hierbei ferner, dass ein Anheben der Schwelle nicht nötig ist, was die Montage wesentlich erschweren würde. Nur so ist eine automatisierte Montage möglich.Then it is for a simple, inexpensive and safe installation of the rail fastening system advantageous if the assembly can be done by moving the clamp from a pre-assembly (with a tightening of the screw with a torque of about 50 Nm) in the final assembly position. It is important that a simple sliding of the tension clamp by means of a slider without prior release of the (biased with said torque) screw can be done. It is also important here that raising the threshold is not necessary, which would make the assembly much more difficult. Only in this way is automated assembly possible.
Ein weiterer Aspekt ist, dass die Schienenbefestigung einen hohen elektrischen Widerstandswert erreicht. Dieser wird zwischen den beiden Schienen auf einer Betonschwelle im nassen Zustand gemessen, d. h. der Widerstandswert wird während einer Dauerberegnung gemessen.Another aspect is that the rail attachment reaches a high electrical resistance. This is measured between the two rails on a concrete sleeper in the wet state, d. H. the resistance value is measured during a continuous irrigation.
Die vorbekannten Schienenbefestigungssysteme weisen hinsichtlich dieser Aufgabenfelder noch Schwachstellen auf.The previously known rail fastening systems still have weak points with regard to these task fields.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Schienenbefestigungssystem der eingangs genannten Art so fortzubilden, dass die oben beschriebenen Anforderungen optimal erfüllt werden können. Demgemäß soll eine einfache und automatisierte Montage des Systems möglich sein, die sich an verschiedene Schienentypen einfach anpassen lässt. Weiterhin soll sich das System durch einen hohen elektrischen Widerstand auszeichnen. Die elektrische Isolation des Systems soll dabei unter allen Umständen sichergestellt sein.The invention is therefore the object of a rail fastening system of the type mentioned in such a way that the requirements described above can be optimally met. Accordingly, a simple and automated installation of the system should be possible, which can be easily adapted to different types of rails. Furthermore, the system should be characterized by a high electrical resistance. The electrical insulation of the system should be ensured under all circumstances.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Isolationselement als Spritzgießformteil ausgebildet ist, wobei dieses aus zwei relativ zueinander klappbaren Teilen besteht, die über einen Scharnierabschnitt miteinander verbunden sind. Hierbei kommt bevorzugt ein Filmscharnier (bzw. Faltscharnier) zum Einsatz. Die beiden zueinander klappbaren Teile können des weiteren mit einem Rast- oder Clipverschluss ausgestattet sein, so dass sie relativ zueinander verbindbar sind.This object is achieved in that the insulating element is formed as an injection molded part, which consists of two relatively foldable parts, which are connected to each other via a hinge portion. Here, a film hinge (or folding hinge) is preferably used. The two mutually folding parts can be further equipped with a locking or clip closure, so that they are connected relative to each other.
Die Spannklemme ist dabei bevorzugt zu einer vertikal verlaufenden Ebene, die von der Schienenlängsachse senkrecht durchsetzt wird, symmetrisch ausgebildet, wobei zwei (End-)Abschnitte der Spannklemme von einem einzigen Isolationselement umgeben sind.The tension clamp is preferably formed symmetrically to a vertically extending plane which is penetrated vertically by the rail longitudinal axis, wherein two (end) portions of the tension clamp are surrounded by a single insulating element.
Die Spannklemme kann aus einem gebogenen Draht mit kreisrundem Querschnitt bestehen, wobei dieser im Bereich des mindestens einen (End-)Abschnitts eine sekantenförmig ausgebildete Abflachung aufweisen kann, wobei das Isolationselement mindestens einen der Form des abgeflachten Abschnitts kongruenten Aufnahmeabschnitt aufweist, bevorzugt zwei dieser Abschnitte in voneinander abgewandten Endabschnitten des Isolationselements. Hierdurch wird das Isolationselement um die Drahtachse drehgesichert festgelegt. Dies hat einen besonderen Effekt, wenn weiterbildungsgemäß vorgesehen ist, dass das Isolationselement an einer Außenseite eine Abflachung aufweist, die der Form der Oberfläche des Schienenfußes angepasst ist, wobei die Abflachung insbesondere eben ausgebildet ist. Dann nämlich wird das Isolationselement - auf die Endabschnitte der Spannklemme montiert - so in Position gehalten, dass die genannte Abflachung passend zur Form des Schienenfußes auf diesem zur Anlage kommt, wodurch im übrigen auch die Montage erleichtert wird.The tensioning clamp can consist of a bent wire with a circular cross-section, wherein this can have a secant-shaped flattening in the region of the at least one (end) section, wherein the insulating element has at least one receiving section congruent to the shape of the flattened section, preferably two of these sections in FIG opposite end portions of the insulating element. As a result, the insulating element is fixed against rotation about the wire axis. This has a particular effect if it is provided according to further development that the insulation element has a flattening on an outer side, which is adapted to the shape of the surface of the rail foot, wherein the flattening is particularly flat. Then that is the insulating element - mounted on the end portions of the tension clamp - held in position so that said flattening matches the shape of the rail foot on this comes to rest, whereby otherwise the assembly is facilitated.
In einer Außenseite des Isolationselements kann eine Ausnehmung eingearbeitet sein, die der Form eines Abschnitts der Spannklemme angepasst ist.In an outer side of the insulating element, a recess may be incorporated, which is adapted to the shape of a portion of the tension clamp.
Das Schienenbefestigungssystem kann des weiteren ein in der Schwelle festgelegtes, insbesondere in das (Beton-)Material der Schwelle eingegossenes, Ankerelement umfassen. Dabei kann dann das Befestigungselement eine formschlüssig im Ankerelement festlegbare Schraube und eine zugehörige Mutter umfassen. Nach dieser Lösung wird also die übliche und allgemein vorbekannte Festlegung der Schiene an der Schwelle mittels einer Schrauben-Dübel-Kombination durch eine Hakenschraube-Mutter-Kombination ersetzt.The rail fastening system may further comprise an anchoring element fixed in the threshold and cast in particular into the (concrete) material of the sleeper. In this case, then, the fastening element comprise a positive lockable in the anchor element screw and an associated nut. After this solution, so the usual and generally known fixing the rail at the threshold by means of a screw-dowel combination is replaced by a hook-nut-nut combination.
Zwischen der Schwelle und dem Schienenfuß ist bevorzugt ein Isolationselement angeordnet. Dieses besteht zumeist aus einem eben bzw. flächig ausgebildeten Gummiteil. Auch die Winkelführungsplatte besteht vorzugsweise aus einem isolierenden Material, insbesondere aus Kunststoff.Between the threshold and the rail foot an insulating element is preferably arranged. This consists mostly of a flat or flat trained Rubber part. The angle guide plate is preferably made of an insulating material, in particular of plastic.
Die Spannklemme kann an ihrer Oberseite mit mindestens einer Abflachung versehen sein, was die Montierbarkeit, d. h. das Verschieben der Spannklemme von der Vormontage- in die Endmontageposition erleichtert.The tension clamp may be provided on its upper side with at least one flattening, which the mountability, d. H. facilitates the movement of the tension clamp from the pre-assembly to the final assembly position.
Mit der vorgeschlagenen Ausbildung des Schienenbefestigungssystems kann erreicht werden, dass ein hoher elektrischer Widerstand zwischen der Schiene und der Schwelle sichergestellt ist, wobei dennoch eine einfache und automatisierbare Montage des Befestigungssystems erfolgen kann.With the proposed design of the rail fastening system can be achieved that a high electrical resistance between the rail and the threshold is ensured, while still a simple and automatable mounting of the fastening system can be done.
Bei der Montage wird die Befestigungsmutter zunächst mit einem vorgegebenen Vormontage-Drehmoment angezogen. Durch Verschieben der Spannklemme horizontal und senkrecht zur Längsachse der Schiene wird die Spannklemme in die Endmontageposition bewegt; das isolierte Ende der Spannklemme gelangt so auf den Schienenfuß, so dass die Schiene auf der Schwelle festgelegt wird.During assembly, the fastening nut is first tightened with a predetermined pre-assembly torque. By moving the tension clamp horizontally and perpendicular to the longitudinal axis of the rail, the tension clamp is moved to the final assembly position; the insulated end of the tension clamp thus comes on the rail foot, so that the rail is fixed on the threshold.

Somit wird eine Verdrehsicherung des Isolators erreicht, sobald er auf die Spannklemmenarme 6' aufgeclipst wird. Die Montage des Isolationselements 8 an der Spannklemme 6 und insbesondere an deren Endabschnitten 6' ist damit in einfacher Weise möglich.The free ends 6 'of the clamping clamp arms are enclosed by the insulating
Auf seiner Oberseite weist das Isolationselement 8 in dem Bereich zwischen den beidseitigen Aufnahmeabschnitten 10 eine Ausnehmung 13 auf. Diese Ausnehmung 13 ist so ausgeformt, dass sie zur Kontur des Mittenabschnitts 6" der Spannklemme 6 passt, d. h. die Ausnehmung 13 kann das geschlossene Ende des Mittenabschnitts 6" aufnehmen. Die Ausnehmung 13 stellt insofern ein tiefer liegendes Lagerbett für den Mittenabschnitt 6" dar, was zur Verringerung der Bauhöhe der Spannklemmen-Isolatoreinheit führt und damit einhergehend zur Verminderung der Bauhöhe im vormontierten Zustand beiträgt. Dies wiederum erleichtert die automatische Montage der Spannklemmen 6 mittels Einbauzügen.On its upper side, the insulating

Die Winkelführungsplatte 5 für einen breiteren Schienenfuß (z. B. des Schienentyps UIC60) weist gegenüber derjenigen für einen schmaleren Schienenfuß (z. B. des Schienentyps U50) einen schmaleren Kopfsteg 23 auf, der die Winkelführungsplatte 5 an ihrer Seite zur Schiene hin begrenzt. Demgemäß ist die Winkelführungsplatte somit in Richtung auf die Schiene gesehen etwas kürzer. Für den breiteren Schienenfuß (UIC60) ist also ein schmalerer Kopfsteg 23 vorhanden und für einen schmaleren Schienenfuß (U50) entsprechend ein breiterer Kopfsteg 24.The wider track rail angle guide plate 5 (eg, the UIC60 rail type) has a
