Gebiet der ErfindungField of the Invention
Die Erfindung betrifft eine elastische Spannkleimme mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an elastic clamping glue with the features of the preamble of claim 1.
Stand der TechnikState of the art
Schienenbefestigungen in Form elastischer Spannklemmen sind seit langem bekannt und haben sich in umfangreichem Einsatz bewährt .Rail fastenings in the form of elastic tension clamps have been known for a long time and have proven themselves in extensive use.
In der Vergangenheit wurden auf Eisenbahnschwellen, insbesondere solchen aus Spannbeton,In the past, railway sleepers, especially prestressed concrete ones,
Schienenbefestigungssyste e mit elastischen Federelementen eingesetzt, die in Draufsicht W-förmig ausgeführt sind.Rail fastening systems with elastic spring elements used, which are designed W-shaped in plan view.
In der DE 32 43 895 wird eine Spannklemme beschrieben, die sich auf der Schwelle bereits im Schwellenwerk vormontieren läßt und zur endgültigen Verspannung der Schiene im Gleis aus ihrer Vormontagestellung um 1802 in die Montagestellung gedreht werden muß. Die Spannkleimme umfaßt ein bogenförmiges Mittelteil mit zwei sich an das Mittelteil anschließenden Schenkeln. Das bogenförmige Mittelteil sowie die sich daran anschließenden Schenkel umgeben in ihrer Einbaustellung den Schaft einer Befestigungsschraube. Die elastische Befestigung der Schiene erfolgt über Biegungen, die sich an die Innenschenkel anschließen und zu freien Enden erstrecken, die auf den Fuß einer Schiene drücken. Zusätzlich zu der elastischen Spannklemme umfaßt die Befestigungsvorrichtung eine Führungsplatte, die jeweils auf jeder Seite des Schienenfußes auf der Schwelle aufliegt und deren Oberflächenkontur an die elastische Spannklemme angepaßt ist, damit die von der Schiene kommenden Kräfte in die Schwelle eingeleitet werden. Die Biegungen der Spannklemme nach der DE 32 43 895 C2 besitzen eine Geometrie, so daß die freien Enden der Biegungen von dem bogenförmigen Mittelteil der Spannklemme so weit beabstandet sind, damit sich baugleiche Spannklemmen miteinander zu langen Ketten verhaken können.DE 32 43 895 describes a tensioning clamp which can be preassembled on the sleeper in the sleeper plant and must be rotated from its pre-assembly position by 180 2 to the assembly position in order to finally brace the rail in the track. The clamping glue comprises an arcuate central part with two legs adjoining the central part. The arch-shaped middle part and the adjoining legs surround the shaft of a fastening screw in their installed position. The elastic fastening of the rail takes place via bends that connect to the inner legs and extend to free ends that press on the foot of a rail. In addition to the elastic tension clamp, the fastening device comprises a guide plate which rests on each side of the rail foot on the sleeper and whose surface contour is adapted to the elastic tension clamp so that the forces coming from the rail are introduced into the sleeper. The bends of the tension clamp according to DE 32 43 895 C2 have a geometry, so that the free ends of the bends are spaced so far from the arcuate central part of the tension clamp so that identical tension clamps can hook together to form long chains.
Aufgrund gestiegener Ansprüche bezüglich der Schienenbefestigung selbst, aber auch einer zunehmenden Automatisierung des Gleisbaus im Rahmen der Vormontage, wurde eine Schienenbefestigung entwickelt, die nicht mehr aus ihrer Vormontagestellung in die Montagestellung gedreht werden muß, sondern horizontal senkrecht zur Schiene verschoben werden kann. Die DE 33 43 119 C2 beschreibt eine derartige Spannklemme. Auch diese Spannklemme wirkt bevorzugt mit einer speziell auf die Spannklemme abgestimmten Rippenplatte zusammen, um die auftretenden Kräfte in die Schwelle einzuleiten .Due to increased demands regarding the rail fastening itself, but also an increasing automation of the track construction during the pre-assembly, a rail fastening was developed, which no longer has to be rotated from its pre-assembly position into the assembly position, but can be moved horizontally perpendicular to the rail. DE 33 43 119 C2 describes such a tension clamp. This tension clamp also preferably interacts with a ribbed plate that is specially matched to the tension clamp in order to introduce the forces that occur into the threshold.
Diese Spannklemme besitzt Vorteile in bezug auf den Komfort bei der Schienenbefestigung, jedoch den Nachteil, daß eine automatische Vormontage nicht möglich ist, da sich in Vorratsbehältern eine Vielzahl von baugleichen Spannklemmen zu langen Ketten miteinander verbinden und von Hand zunächst vereinzelt werden müssen. Unter dem Verketten von Spannklemmen soll im folgenden verstanden werden, dass sich viele Spannklemmen jeweils miteinander verhaken. Darstellung der ErfindungThis tension clamp has advantages in terms of comfort when mounting the rails, but the disadvantage that automatic pre-assembly is not possible, since a large number of identical tension clamps connect to one another in long containers to form long chains and must first be separated by hand. In the following, the chaining of tensioning clamps should be understood to mean that many tensioning clamps get caught with each other. Presentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Schienenbefestigung zu entwickeln, die einfach und automatisch auf Eisenbahnschwellen vormontierbar ist.The invention has for its object to develop a rail fastening that can be easily and automatically preassembled on railway sleepers.
Diese Aufgabe wird durch eine elastische Spannklemme mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by an elastic tension clamp with the features of claim 1.
Der Erfindung liegt der Gedanke zugrunde, die Spannklemme bezüglich der Dimensionen so zu gestalten, daß der freie Abstand zwischen dem bogenförmigen Mittelteil und der Schlaufe im Bereich des freien Endes kleiner als der Durchmesser des Federstahls ist, aus dem die Spannklemme gefertigt ist. Hierdurch wird einem Verketten der Spannklemmen entgegengewirkt. Daher kann im Rahmen der Vormontage eine automatische Entnahme einzelner Spannklemmen aus einem Vorratsbehälter durchgeführt werden. Selbst bei einer manuellen Vormontage bietet die erfindungsgemäße elastische Spannklemme Vorteile, da auch das Montagepersonal nur die einzelnen Spannklemmen aus einem Vorratsbehälter entnehmen, nicht aber eventuell gebildete Ketten von Spannklemmen voneinander lösen muß.The invention is based on the idea of designing the tension clamp with respect to the dimensions so that the free distance between the arcuate central part and the loop in the region of the free end is smaller than the diameter of the spring steel from which the tension clamp is made. This counteracts chaining of the tension clamps. Therefore, during the pre-assembly, an automatic removal of individual tension clamps can be carried out from a storage container. Even in the case of manual pre-assembly, the elastic tension clamp according to the invention offers advantages, since the assembly personnel also only have to remove the individual tension clamps from a storage container, but do not have to detach any chains of tension clamps which may have formed.
Nach einer alternativen, bevorzugten Ausführungsform befinden sich an den freien Enden der Spannklemme Verdickungen oder Aufstauchungen. Derartige Verdickungen und AufStauchungen können ebenfalls den Abstand zwischen den freien Enden und dem bogenförmigen Mittelteil soweit verringern, daß ein Verketten von Spannklemmen sicher vermieden werden kann.According to an alternative, preferred embodiment, there are thickenings or upsets at the free ends of the tension clamp. Such thickening and upsetting can also reduce the distance between the free ends and the arcuate central part to such an extent that a chaining of clamping clamps can be safely avoided.
Nach einer bevorzugten Ausführungsform der Erfindung liegen die freien Enden der Spannklemme aneinander an. Durch das Aneinanderanlegen der freien Enden der Spannklemme alleine kann ein Verketten nicht verhindert werden, da bei einem entsprechenden Abstand zwischen den freien Enden und dem bogenförmigen Mittelteil noch immer ein Ineinandereingreifen zweier baugleicher Spannklemmen erfolgen kann. Diese Geometrie besitzt jedoch den Vorteil, daß ein Verkanten und gegenseitiges Verklemmen von Spannklemmen in einem Vorratsbehälter vermieden werden kann, auch wenn durch die Grundgeometrie ohnehin bereits ein Verketten ausgeschaltet ist .According to a preferred embodiment of the invention, the free ends of the tension clamp abut each other. Linking the free ends of the tension clamp alone cannot prevent a chaining, since with a corresponding distance between the free ends and the arcuate central part, there is still an engagement two identical clamps can be made. However, this geometry has the advantage that tilting and jamming of tension clamps in a storage container can be avoided, even if chaining is already switched off due to the basic geometry.
Nach einer bevorzugten Ausführungsform der Erfindung verlaufen die Innenschenkel im wesentlichen parallel zueinander. Diese Formgebung gestattet es, daß die elastische Spannklemme sowohl horizontal senkrecht zur Schiene aus ihrer Vormontagestellung in die Montagestellung verschoben werden kann, als auch als Ersatz für Spannklemmen verwendet werden kann, die zur endgültigen Verspannung der Schiene im Gleis aus ihrer Vormontagestellung in die Montagestellung um 1802 gedreht werden müssen. Darüber hinaus wird durch die parallele Führung der Innenschenkel ohne eine Einschnürung der Mittelschleife die automatische Vormontage erleichtert.According to a preferred embodiment of the invention, the inner legs run essentially parallel to one another. This design allows the elastic tension clamp to be moved both horizontally perpendicular to the rail from its pre-assembly position to the assembly position, and also to be used as a replacement for tension clamps that are used to finally brace the rail in the track from its pre-assembly position to the assembly position by 180 2 must be rotated. In addition, automatic pre-assembly is facilitated by the parallel guidance of the inner legs without constricting the middle loop.
Vorzugsweise umfassen die Schlaufen einen sich an den jeweiligen Innenschenkel anschließenden hinteren Stützbogen sowie einen Außenschenkel, der sich an den hinteren Stützbogen anschließt, wobei der hintere Stützbogen so gestaltet ist, daß der Abstand D zwischen dem Innenschenkel und der parallelen Tangente hierzu am Außenschenkel D ≥ 50 mm, bevorzugt D ≥ etwa 60 mm beträgt.The loops preferably comprise a rear support arch adjoining the respective inner leg and an outer leg adjoining the rear support arch, the rear support arch being designed such that the distance D between the inner leg and the parallel tangent thereto on the outer leg D ≥ 50 mm, preferably D ≥ about 60 mm.
Aufgrund der Problematik des Verkettens mehrerer Spannklemmen miteinander wurde bislang davon Abstand genommen, Schlaufen mit einer großen Länge und somit einem großen umschlossenen Raum vorzusehen, da dies das unerwünschte Verketten mehrerer Spannklemmen mit der Schlaufe einer einzigen Spannklemme förderte. Wenn sich einmal mehrere Spannklemmen in der Schlaufe einer Spannklemme verkettet haben, ist es auch für geschultes Personal schwierig, die mehreren Spannklemmen wieder voneinander zu lösen, da der Bewegungsspielraum für das korrekte Anordnen der Spannklemmen zum Lösen derselben eingeschränkt ist und aufgrund der ebenfalls in der Schlaufe verhakten anderen Spannklemmen eingeschränkt wird. Andererseits ist man bestrebt, den Abstand zwischen dem Innenschenkel und der parallelen Tangente hierzu zum Außenschenkel groß zu gestalten, damit der Torsionsanteil bei der vertikalen Bewegung der freien Enden der Spannklemme auf dem Schienenfuß von diesem Bereich aufgenommen wird und die TorsionsSpannungen aufgrund der größeren Länge dieses Abschnittes leichter von der Spannklemme aufgenommen werden können. Durch das erfindungsgemäße Vermeiden einer Verhakung von Spannklemmen miteinander läßt sich somit die gesamte Geometrie besser an die immer weiter wachsenden Erfordernisse an eine Schienenbefestigung anpassen.Due to the problem of chaining several tension clamps together, it has so far been refrained from providing loops with a long length and thus a large enclosed space, since this promoted the undesired chaining of several tension clamps with the loop of a single tension clamp. Once several tension clamps have been chained in the loop of a tension clamp, it is also difficult for trained personnel to separate the several tension clamps from one another again, since there is the freedom of movement for the correct arrangement of the tension clamps to loosen them is restricted and is restricted due to the other tension clamps which are also hooked in the loop. On the other hand, efforts are being made to make the distance between the inner leg and the parallel tangent to the outer leg large so that the torsional component is absorbed by this area during the vertical movement of the free ends of the tension clamp on the rail foot and the torsional stresses due to the greater length of this section can be more easily picked up by the tension clamp. By avoiding the hooking of clamping clamps with one another according to the invention, the entire geometry can thus be better adapted to the ever-increasing requirements for rail fastening.
Insbesondere beim Auswechseln bestehender Spannklemmen, die zur endgültigen Verspannung der Schiene aus ihrer Vormontagestellung in die Montagestellung um 1802 gedreht werden müssen, kann die erfindungsgemäße Spannklemme eingesetzt werden, ohne die Schrauben auswechseln zu müssen.In particular when replacing existing tension clamps which have to be rotated by 180 2 from their pre-assembly position to the assembly position in order to finally brace the rail, the tension clamp according to the invention can be used without having to replace the screws.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
In den nachfolgenden Figuren werden zur einfacheren Bezugnahme jeweils gleiche oder ähnliche Abschnitte der Spannklemmen mit denselben Referenzziffern bezeichnet werden.In the following figures, the same or similar sections of the tension clamps will be designated with the same reference numerals for easier reference.
In Fig. 8a und 8b sind herkömmliche Spannklemmen gezeigt, die jeweils mit 10.1 sowie 10.2 bezeichnet sind. Die Zusätze .1 sowie .2 sollen jeweils die beiden zusammenwirkenden, baugleichen Spannklemmen bezeichnen. Die Spannklemmen bestehen aus einem bogenförmigen Mittelteil 14, zwei sich an das bogenförmige Mittelteil anschließende Innenschenkel 12 sowie Schlaufen 16, die sich jeweils an die Innenschenkel anschließen und in freien Enden 18 abschließen.8a and 8b show conventional tension clamps, which are each designated 10.1 and 10.2. The additions .1 and .2 are to designate the two interacting, identical clamping clamps. The tensioning clamps consist of an arcuate central part 14, two inner legs 12 adjoining the arcuate central part and loops 16, each of which connect to the inner legs and terminate in free ends 18.
Aufgrund der geometrischen Beziehungen der oben beschriebenen Abschnitte der Spannklemmen zueinander ist es möglich, daß die beiden Spannklemmen 10.1 und 10.2 miteinander verhaken. Dies erfolgt, indem zwischen einem der freien Enden 18.1 der ersten Spannklemme und dem entsprechenden Mittelteil 14.1 das freie Ende 18.2 der zweiten Spannklemme sowie das zugehörige Mittelteil 14.2 hindurchtreten können. Ist der Abstand zwischen dem freien Ende 18 und dem Mittelteil 14 größer als der Durchmesser d, so kann ein Verhaken zweier Spannklemmen an beliebiger Stelle erfolgen, indem, wie in Fig. 8b dargestellt ist, die Spannklemme 10.2 im Bereich ihrer Schlaufe 16.2 zwischen dem freien Ende 18 und dem Mittelteil 14 der Spannklemme 10.1 hindurchtritt.Due to the geometrical relationships of the sections of the tension clamps described above, it is possible for the two tension clips 10.1 and 10.2 to get caught. This is done by allowing the free end 18.2 of the second tension clamp and the associated middle part 14.2 to pass between one of the free ends 18.1 of the first tension clamp and the corresponding middle part 14.1. If the distance between the free end 18 and the central part 14 is greater than the diameter d, two tensioning clamps can get caught at any point by, as shown in FIG. 8b, the tensioning clamp 10.2 in the area of its loop 16.2 between the free End 18 and the central part 14 of the clamp 10.1 passes.
Aus Computersimulationen läßt sich zeigen, daß die Möglichkeit eines miteinander Verhakens zweier baugleicher Spannklemmen nicht alleine vom lichten Abstand zwischen dem freien Ende 18 und dem Mittelteil 14 abhängt, sondern sich die Engstelle auch in einer Entfernung vom freien Ende befinden kann und zudem der komplexe und häufig nicht-lineare Bewegungsablauf beim möglichen Verhaken von baugleichen Spannklemmen mitberücksichtigt werden muß.From computer simulations it can be shown that the possibility of interlocking two identical tension clamps does not only depend on the clear distance between the free end 18 and the central part 14, but the constriction can also be at a distance from the free end and also the complex and frequent Non-linear movement sequence must be taken into account when interlocking identical clamps.
Ein Verketten tritt allerdings nur dann auf, wenn die statistische Wahrscheinlichkeit eines möglichen Verhakens so groß ist, dass es zur Bildung von Ketten miteinander verhakter Spannklemmen kommen kann. Ein einzeln auftretendes Verkeilen oder Verhaken zweier Spannklemmen ist unschädlich, weil dies nicht zur Ausbildung langer Ketten führt.However, chaining only occurs when the statistical likelihood of possible hooking is so great that chains of interlocking clamps can form. A single wedging or hooking of two tension clamps is harmless because this does not lead to the formation of long chains.

freien Endes 26 ist, wodurch sich mehrere Spannklemmen nicht miteinander verketten können.Free end 26 is, so that several clamps can not chain together.
Wie zusätzlich aus der Darstellung in den Fig. la bis lc und insbesondere aus Fig. lc ersichtlich ist, ist der hintere Stützbogen so ausgebildet, daß dieser eine große Länge D besitzt, die als Abstand zwischen der Achse des Innenschenkels und der parallelen Tangente durch den Mittelpunkt des Außenschenkels entspricht. Dieser Abstand D sollte mindestens 50 mm betragen, damit die dargestellte Spannklemme einen hohen Torsionsweg gewährleisten kann, wodurch die Federsteifigkeit verringert werden kann. Allerdings ist auch die Geometrie der Schlaufe hierfür mitentscheidend. So sollten die Außenschenkel der Schlaufen einen Bogen beschreiben, dessen Sekante S (siehe Fig. lb) im wesentlichen parallel zum Verlauf der Innenschenkel ist.As can additionally be seen from the illustration in FIGS. 1 a to 1 c and in particular from FIG. 1 c, the rear support arch is designed such that it has a large length D, which is the distance between the axis of the inner leg and the parallel tangent through the The center of the outer leg corresponds. This distance D should be at least 50 mm, so that the tension clamp shown can ensure a high torsion path, which can reduce the spring stiffness. However, the geometry of the loop is also decisive for this. So the outer legs of the loops should describe an arc, the secant S (see Fig. Lb) is substantially parallel to the course of the inner legs.
Diese Geometrie ist insbesondere beim Einsatz der Spannklemme an problematischen Streckenabschnitten vom Vorteil. So können beispielsweise im Bereich von Steigungen durch das Durchrutschen der Räder von Schienenfahrzeugen hochfrequente Schwingungen entstehen, die eine Bewegung der Schienen in Längsrichtung trotz ordnungsgemäß befestigter Spannklemmen auslösen. Das Vorsehen eines größeren Torsionsabschnittes erhöht die Dauerfestigkeit der Schienenverbindung, da nicht nur der Torsionsanteil der Schlaufe erhöht ist, sondern auch eine relative Vergrößerung des Biegeradius in Schienenrichtung erfolgt.This geometry is particularly advantageous when using the tension clamp on problematic sections of the route. For example, high-frequency vibrations can occur in the area of slopes due to the slipping of the wheels of rail vehicles, which triggers a movement of the rails in the longitudinal direction despite properly tightened clamping clamps. The provision of a larger torsion section increases the fatigue strength of the rail connection, since not only is the torsion portion of the loop increased, but there is also a relative increase in the bending radius in the direction of the rail.
Die Fig. 2 bis 5b zeigen jeweils Möglichkeiten, um den freien Abstand zwischen dem bogenförmigen Mittelteil und der Schlaufe im Bereich des freien Endes gering zu gestalten. So ist in Fig. 2 dargestellt, daß sich die Länge des Mittelteils und somit die Länge der Innenschenkel 12 erhöhen läßt, um eine geringere Entfernung zwischen dem bogenförmigen Mittelteil und den freien Enden 26 der Schlaufen 16 zu erzeugen. Eine alternative, in Fig. 3 dargestellte Ausführungsform ist der in Fig. 2 dargestellten Ausführungsalternative ähnlich, verlängert jedoch die freien Enden 26 soweit, daß sich nur noch ein geringer Abstand d2 zwischen den freien Enden 26 befindet. Die Annäherung der freien Enden 26 alleine kann jedoch ein Verketten nicht verhindern; es muß entsprechend den oben dargelegten Ausführungen auch auf den entsprechend gering gewählten freien Abstand zwischen den jeweiligen, einzelnen freien Enden 26 und den bogenförmigen Mittelteil 14 in gleicher Weise geachtet werden.2 to 5b each show possibilities for making the free distance between the arcuate central part and the loop small in the area of the free end. Thus, it is shown in Fig. 2 that the length of the central part and thus the length of the inner legs 12 can be increased to produce a shorter distance between the arcuate central part and the free ends 26 of the loops 16. An alternative embodiment shown in FIG. 3 is similar to the embodiment alternative shown in FIG. 2, but extends the free ends 26 to such an extent that there is only a small distance d2 between the free ends 26. However, the approach of the free ends 26 alone cannot prevent chaining; according to the explanations set out above, attention must also be paid in the same way to the correspondingly small free distance between the respective individual free ends 26 and the arcuate central part 14.
Eine alternative Ausführungsform ist aus den Fig. 4a und 4b ersichtlich, wobei Fig. 4a eine Draufsicht auf diese Ausführungsform der Spannklemme und Fig. 4b eine Seitenansicht derselben darstellt. Wie sich aus der Grundgeometrie der in Fig. 4a dargestellten Spannklemme ergibt, ist diese der in den Fig. la bis lc dargestellten Spannklemme im Bezug auf die Länge des Mittelteiles und die Krümmung der Schlaufen 16 sehr ähnlich. Der wesentliche Unterschied liegt darin, daß sich an den freien Enden 26 Verdickungen 28 befinden, welche den freien Abstand zwischen dem bogenförmigen Mittelteil und den Verdickungen der freien Enden soweit verringern, daß ein Verketten wirkungsvoll vermieden werden kann. Die Verdickungen 28 können als AufStauchungen der Enden gebildet sein und erfordern einen erhöhten fertigungstechnischen Aufwand. Der Vorteil der Verdickungen liegt jedoch darin, daß ein größerer freier Abstand zwischen dem bogenförmigen Mittelteil und dem verdickten Ende des freien Endes 26 möglich ist. Dies kann aus fertigungstechnischer Sicht günstig sein, wenn bei den einzelnen Biegeschritten der Federstahl der Spannklemme stark zurückfedert und es daher aufgrund geometrischer Beschränkungen nicht möglich ist, die freien Enden soweit dem bogenförmigen Mittelteil anzunähern, daß ein Verketten verhindert werden kann. Die Fig. 5a und 5b zeigen schließlich eine alternative Ausführungsform, deren Innenschenkel nicht durch ein bogenförmiges Mittelteil miteinander verbunden sind. Anstelle dessen liegen keine freien Enden 26 vor, sondern ist die Spannklemme in diesem Bereich durchgehend hergestellt. Trotz der recht unterschiedlich wirkenden Anordnung der Enden relativ zu den durchlaufenden Bereichen entwickelt sich jedoch dieselbe Grundgeometrie, nach der der freie Abstand zwischen den im vorliegenden Fall an den Innenschenkeln 12 angeordneten freien Enden und der durchgehenden Schlaufe 30 gebildete freie Abstand ebenfalls so klein gewählt werden muß, daß ein Verketten nicht möglich ist.An alternative embodiment can be seen from FIGS. 4a and 4b, FIG. 4a showing a top view of this embodiment of the tension clamp and FIG. 4b showing a side view thereof. As can be seen from the basic geometry of the tension clamp shown in FIG. 4 a, this is very similar to the tension clamp shown in FIGS. 1 a to 1 c with respect to the length of the middle part and the curvature of the loops 16. The essential difference is that there are thickenings 28 at the free ends, which reduce the free distance between the arcuate central part and the thickenings of the free ends to the extent that concatenation can be effectively avoided. The thickenings 28 can be formed as upsetting of the ends and require an increased manufacturing outlay. The advantage of the thickening is, however, that a larger free distance between the arcuate central part and the thickened end of the free end 26 is possible. This can be advantageous from a production point of view if the spring steel of the tension clamp springs back strongly at the individual bends and it is therefore not possible due to geometrical restrictions to approach the free ends as far as the arc-shaped central part that a chaining can be prevented. 5a and 5b finally show an alternative embodiment, the inner legs of which are not connected to one another by an arcuate central part. Instead of this there are no free ends 26, but the tension clamp is produced continuously in this area. Despite the arrangement of the ends acting quite differently relative to the continuous areas, however, the same basic geometry develops, according to which the free distance between the free ends arranged on the inner legs 12 in the present case and the continuous loop 30 must also be chosen so small that chaining is not possible.
Um zu verdeutlichen, daß mit den vorgeschlagenen Spannklemmen ein gegenseitiges Einrücken der Schlaufe einer Spannklemme in die Schlaufe einer baugleichen Spannklemme nicht länger möglich ist, soll das Ausführungsbeispiel gemäß den Fig. 4a und 4b in der Fig. 7 in einer entsprechenden Position dargestellt werden. Die Fig. 7 zeigt, daß aufgrund der Verdickungen 28.1 an der Spannklemme 10.1 sowie 28.2 an der Spannklemme 10.2 kein Verhaken der Schlaufen 16.1 sowie 16.2 mehr möglich ist. In gleicher Weise zeigen die Figuren 6a und 6b anhand der in den Figuren la bis lc dargestellten Ausführungsvariante, daß ebenfalls mit dieser dargestellten Geometrie kein Verhaken der beiden Spannklemmen mehr möglich ist .In order to clarify that a mutual engagement of the loop of a tension clamp in the loop of an identical tension clamp is no longer possible with the proposed tension clamps, the embodiment according to FIGS. 4a and 4b in FIG. 7 should be shown in a corresponding position. FIG. 7 shows that, due to the thickenings 28.1 on the tension clamp 10.1 and 28.2 on the tension clamp 10.2, it is no longer possible for the loops 16.1 and 16.2 to get caught. In the same way, FIGS. 6a and 6b show on the basis of the embodiment variant shown in FIGS.
Indem einem Verketten der Spannklemmen entgegengewirkt wird, lassen sich die Schlaufen entsprechend groß dimensionieren, da die Gefahr einer Verkettung mehrerer Spannklemmen nicht länger besteht. Hierdurch besteht die Möglichkeit, die Biegeradien in Schienenrichtung zu vergrößern und den Torsionsanteil zu erhöhen, so daß die Spannklemmen eine verbesserte Federcharakteristik aufweisen. Durch das Verlängern der freien Enden im Rahmen der Verringerung des freien Abstandes lassen sich zudem größere Flächenpressungen auf dem Schienenfuß erzielen. Hierdurch werden im Vergleich zu bekannten, ebenfalls W-förmig geformten Spannklemmen mindestens gleiche technische Eigenschaften, insbesondere hinsichtlich der Elastizität in vertikaler und horizontaler Richtung sowie in Längs- und Querrichtung zur Schiene erzeugt. Darüber hinaus wird eine einfache und automatische Vormontage von Eisenbahnschwellen möglich, auf der anderen Seite aber auch durch das Vorsehen parallel zueinander verlaufender Innenschenkel eine mit möglichst geringem Aufwand realisierbare Austauschbarkeit sowohl gegenüber Spannklemmen von dem gleichen Typ wie auch gegenüber bereits bekannten, ähnlich geformten Modellen. By counteracting a chaining of the tensioning clamps, the loops can be dimensioned correspondingly large, since there is no longer a risk of chaining several tensioning clamps. This makes it possible to increase the bending radii in the rail direction and to increase the proportion of torsion, so that the tension clamps have an improved spring characteristic. By extending the free ends as part of the reduction in the free distance, larger surface pressures can also be achieved on the rail foot. This compares to known, also W-shaped clamping clamps at least the same technical properties, in particular with regard to the elasticity in the vertical and horizontal direction and in the longitudinal and transverse directions to the rail. In addition, a simple and automatic pre-assembly of railway sleepers is possible, but on the other hand, by providing inner legs running parallel to each other, interchangeability can be achieved with as little effort as possible, both with tension clamps of the same type and with already known, similarly shaped models.
