Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft eine elastische Spannklemme mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an elastic tension clamp 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 fasteners in the form of elastic clamps are have long been known and have been in extensive use proven.

In der Vergangenheit wurden auf Eisenbahnschwellen, insbesondere solchen aus Spannbeton, Schienenbefestigungssysteme mit elastischen Federelementen eingesetzt, die in Draufsicht W-förmig ausgeführt sind.In the past, on railway sleepers, especially those made of prestressed concrete, Rail fastening systems with elastic spring elements used, which are executed in plan view W-shaped.

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 180º in die Montagestellung gedreht werden muß. Die Spannklemme 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 längen Ketten verhaken können.In DE 32 43 895 a tension clamp is described, the already pre-assembled on the threshold in the sleeper factory leaves and to the final tension of the rail in the track their pre-assembly position by 180 ° in the mounting position must be turned. The tension clamp comprises a bow-shaped Middle part with two adjoining the middle part Thighs. The arcuate middle part and the itself subsequent leg surrounded in its installed position the Shaft of a fastening screw. The elastic attachment The rail takes over bends, which are connected to the Connect inner leg and extend to free ends that Press on the foot of a rail. In addition to the elastic tensioning clamp comprises the fastening device a guide plate, each on each side of the Rail foot rests on the threshold and their Surface contour is adapted to the elastic tension clamp, thus the forces coming from the rail into the threshold be initiated. The bends of the tension clamp after the DE 32 43 895 C2 have a geometry so that the free Ends of the bends of the arcuate center of the Clamp are spaced so far so that identical Clamps with each other to length chains can hook.

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 34 119 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 claims regarding the Rail fastening itself, but also an increasing Automation of track construction in the context of pre-assembly, was developed a rail fastening, which is no longer from their Vormontagestellung must be rotated in the mounting position, but be moved horizontally perpendicular to the rail can. DE 33 34 119 C2 describes such Tension clamp. This tension clamp also preferably works with a specially adapted to the tension clamp ribbed plate Together, the forces occurring in the threshold initiate.

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. This tension clamp has advantages in terms of comfort in the rail fastening, but the disadvantage that a automatic pre-assembly is not possible, since in Reservoirs a variety of identical clamps connect to long chains together and by hand first must be isolated. Under the chaining of Clamps will be understood in the following that hook many clamps together.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, eine Schienenbefestigung zu entwickeln, die einfach und automatisch auf Eisenbahnschwellen vormontierbar ist.The invention is based on the object To develop rail fastening that is simple and easy automatically preassembled on railway sleepers.

Diese Aufgabe wird durch eine elastische Spannklemme mit den Merkmalen des Anspruchs 1 gelöst.This task is accomplished by an elastic tension clamp with the Characteristics of claim 1 solved.

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 the tension clamp in terms of dimensions so that the free Distance between the arcuate middle part and the Loop in the area of the free end smaller than the Diameter of the spring steel is from which the tension clamp is made. This is a chaining the Counteracted clamping clamps. Therefore, under the Pre-assembly automatic removal of individual clamps be carried out from a storage container. Even at a manual pre-assembly offers the inventive elastic tension clamp advantages, as well as the assembly staff only the individual clamps from a reservoir but not possibly formed chains of Clamps must solve each other.

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 at the free ends of the tension clamp thickening or Aufstauchungen. Such thickening and buckling can also change the distance between the free ends and reduce the arcuate middle part so far that a Chaining of 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 clamp to each other. By the Attaching the free ends of the tension clamp alone can not be prevented from daisy chaining, because at one corresponding distance between the free ends and the arcuate middle part still an intermeshing two identical clamps can be done. These However, geometry has the advantage that tilting and mutual jamming of clamps in one Reservoir can be avoided, even if by the Basic geometry already switched off a chaining anyway is.

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 180º 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 are substantially parallel to each other. This shaping allows the elastic Clamp both horizontally perpendicular to the rail from its Pre-assembled to be moved to the mounting position can be used as well as a replacement for tension clamps That can lead to the final bracing of the rail in the track from its pre-assembly to the assembly position by 180º have to be turned. In addition, by the parallel guidance of the inner leg without a constriction the center loop facilitates automatic pre-assembly.

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.Preferably, the loops comprise a to the respective inner leg adjoining rear support arch as well as an outer leg, which adjoin the rear Support bow connects, with the rear support arch so is 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 clamps so far they have refrained from each other, loops with a large length and thus a large enclosed Provide space as this is the undesirable chaining of several Clamps with the loop of a single clamp promoted. If once several clamps in the Chained loop of a tension clamp, it is also for trained personnel difficult, the several clamps to solve each other again, because the range of motion for the correct placement of the clamps to release the same is restricted and due to which also in the loop hooked other clamps is restricted. On the other hand, one strives to reduce the distance between the Inner leg and the parallel tangent to this Make outer thighs large, so that the torsion at the vertical movement of the free ends of the tension clamp on the rail foot is taken up by this area and the Torsional stresses due to the greater length of this Section easier to be absorbed by the tension clamp can. By avoiding entanglement according to the invention From clamps with each other can thus be the entire Geometry better to the ever-growing requirements adapt to a rail fastening.

Insbesondere beim Auswechseln bestehender Spannklemmen, die zur endgültigen Verspannung der Schiene aus ihrer Vormontagestellung in die Montagestellung um 180° gedreht werden müssen, kann die erfindungsgemäße Spannklemme eingesetzt werden, ohne die Schrauben auswechseln zu müssen.In particular, when replacing existing clamps, the for the final bracing of the rail from her Pre-assembly position turned in the mounting position by 180 ° must be, the tension clamp according to the invention be used without having to replace the screws.

Wege zur Ausführung der ErfindungWays to carry 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 become easier Reference to the same or similar sections of the Clamps are designated by the same reference numerals.

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.In Fig. 8a and 8b conventional tensioning clamps are shown, the each with 10.1 and 10.2 are designated. The additives .1 as well as .2 the two cooperating, designate identical clamping terminals. The clamps consist of an arcuate middle part 14, two at the arcuate middle part adjoining inner leg 12th as well as loops 16, each attached to the inner thighs connect 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 geometric relationships of the above Sections of the clamps to each other, it is possible that Hook the two tension clamps 10.1 and 10.2 together. This is done by between one of the free ends 18.1 of first tension clamp and the corresponding middle part 14.1 the free end 18.2 of the second tension clamp and the associated Center part 14.2 can pass. Is the distance between the free end 18 and the middle part 14 is greater than the diameter d, so can hooking two clamps take place at any point by, as in Fig. 8b is shown, the tension clamp 10.2 in the area of her Loop 16.2 between the free end 18 and the Middle 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 can be shown that the Possibility of interlocking two identical Clamps not alone from the clearance between the free end 18 and the middle part 14 depends, but itself the bottleneck also at a distance from the free end and more complex and often non-linear Movement when possible hooking of identical Clamps must be taken into account.

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, concatenation only occurs when the statistical probability of a possible entanglement so it is great that there is formation of chains with each other hooked clamps can come. A single occurrence Wedging or catching two tension clamps is harmless, because this does not lead to the formation of long chains.

Wendet man sich den Fig. 1a, 1b sowie 1c zu, so ist eine erste Ausführungsform der erfindungsgemäßen Spannklemme dargestellt. Die Spannklemme 10 umfaßt zwei Schlaufen 16, die sich an einen Mittelteil anschließen, der im wesentlichen aus zwei Innenschenkeln 12 gebildet ist, die, wie aus Fig. 1b ersichtlich ist, parallel zueinander verlaufen. Zwischen den Innenschenkeln 12 wird im Montagezustand eine Schwellenschraube (nicht dargestellt) geführt, die im Montagezustand auf Abflachungen 20 im Bereich der Oberseite der Innenschenkel 12, ggf. unter Vermittlung einer Beilagscheibe, aufliegt. Bei der Montage wird die Schwellenschraube mittels eines Drehmomentschlüssels, der am Kopf der Schwellenschraube angreift, in einen in der Schwelle befindlichen Kunststoffdübel in bekannter Weise eingeschraubt, bis die gewünschte Spannkraft hergestellt ist.Turning to Figs. 1a, 1b and 1c, so is a first embodiment of the tension clamp according to the invention shown. The tension clamp 10 comprises two loops 16, the connect to a middle part, which consists essentially of two inner legs 12 is formed, which, as shown in Fig. 1b is apparent, parallel to each other. Between Inner legs 12 is in the assembled state a Threshold screw (not shown) guided in the Mounting state on flats 20 in the top the inner leg 12, possibly with the mediation of a Washer, rests. During assembly, the Threshold screw by means of a torque wrench, the Head of the sleeper screw attacks, in one in the threshold located plastic dowels in a known manner screwed in until the desired clamping force is produced.

Aufgrund der Formgebung der parallel zueinander angeordneten Innenschenkel ist sowohl eine Verschiebebewegung horizontal senkrecht zur Schiene zwischen der Vormontagestellung und der Montagestellung wie auch ein Drehen um 180º von der Vormontagestellung in die Montagestellung realisierbar. Darüber hinaus ist es möglich, eine Spannklemme mit ebenfalls parallel zueinander verlaufenden Innenschenkeln durch die in den Fig. 1a bis 1c dargestellte Spannklemme zu ersetzen, indem lediglich die Schwellenschraube gelockert wird und die Spannklemmen durch eine Dreh- sowie Verschiebebewegung jeweils ausgetauscht werden.Due to the shape of the arranged parallel to each other Inner leg is both a sliding movement horizontal perpendicular to the rail between the pre-assembly and the Assembly as well as a turn of 180º from the Pre-assembly in the mounting position feasible. In addition, it is possible to use a tension clamp as well parallel inner legs through the in to replace the clamp shown in FIGS. 1a to 1c, by only the sleeper screw is loosened and the Clamps by a rotary and sliding movement each to be exchanged.

Im vorliegenden Ausführungsbeispiel sind die Innenschenkel durch ein bogenförmiges Mittelteil 14 miteinander verbunden. Auf der relativ zum bogenförmigen Mittelteil entgegengesetzten Seite der Innenschenkel schließen sich die Schlaufen 16 an, die selbst aus einem hinteren Stützbogen 22, Außenschenkeln 24 und miteinander fluchtenden freien Enden 26 bestehen.In the present embodiment, the inner legs connected by an arcuate central part 14 with each other. On the relative to the arcuate middle section opposite side of the inner thighs close the Loops 16, themselves from a rear support bow 22, Outer legs 24 and aligned free ends 26th consist.

Die freien Enden 26 sind im vorliegenden Ausführungsbeispiel relativ zum bogenförmigen Mittelteil 14 so angeordnet, daß der freie Abstand zwischen dem Mittelteil 14 und der Schlaufe 16 im Bereich der jeweiligen freien Enden 26 geringer als der Durchmesser des Federstahls im Bereich des freien Endes 26 ist, wodurch sich mehrere Spannklemmen nicht miteinander verketten können.The free ends 26 are in the present embodiment relative to the arcuate central portion 14 so arranged that the free distance between the middle part 14 and the Loop 16 in the region of the respective free ends 26 less than the diameter of the spring steel in the area of free end 26, which does not cause several clamps can chain together.

Wie zusätzlich aus der Darstellung in den Fig. 1a bis 1c und insbesondere aus Fig. 1c 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. 1b) im wesentlichen parallel zum Verlauf der Innenschenkel ist.As additional from the illustration in Figs. 1a to 1c and in particular from Fig. 1c can be seen, is the rear Support bow designed so that this has a large length D possesses, as the distance between the axis of Inner leg and the parallel tangent through the Center of the outer leg corresponds. This distance D should be at least 50 mm, so that the illustrated Tensioning clamp can ensure a high torsion, whereby the spring stiffness can be reduced. However, the geometry of the loop is for this purpose decisive. So should the outer thighs of the loops describe an arc whose secant S (see Fig. 1b) in is essentially parallel to the course of the inner leg.

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 especially true when using the tension clamp on problematic sections of the advantage. So can for example in the range of slopes through the Slipping of the wheels of rail vehicles high-frequency Vibrations occur that cause a movement of the rails in Longitudinal direction despite properly fastened tension clamps trigger. The provision of a larger torsion section increases the fatigue strength of the rail connection, as not only the torsional portion of the loop is increased, but also a relative increase in the bending radius in Rail direction is done.

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. Figs. 2 to 5b each show ways to the free Distance between the arcuate middle part and the Loop in the area of the free end to make small. So is shown in Fig. 2 that the length of the central part and thus increase the length of the inner leg 12 to a smaller distance between the arcuate Middle part and the free ends 26 of the loops 16 to produce.

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.An alternative embodiment shown in FIG. 3 is similar to the alternative embodiment shown in FIG. 2, however, extends the free ends 26 so far that only still a small distance d2 between the free ends 26 located. The approach of the free ends 26 alone can however, do not prevent a chaining; it must be done accordingly the above explanations also to the corresponding slightly chosen free space between the respective, individual free ends 26 and the arcuate middle part 14th be respected in the same way.

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. 1a bis 1c 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. An alternative embodiment is shown in FIGS. 4a and 4b can be seen, with Fig. 4a is a plan view of this Embodiment of the tension clamp and Fig. 4b a Represents side view of the same. As is clear from the Basic geometry of the tension clamp shown in Fig. 4a This results in the one shown in Figs. 1a to 1c Clamp in relation to the length of the middle part and the Curvature of the loops 16 very similar. The essential The difference is that at the free ends 26 Thickenings 28 are located, indicating the free distance between the arcuate middle part and the thickenings of the free Reduce ends so far that chaining is effective can be avoided. The thickenings 28 can as Buckling of the ends can be formed and require one increased production costs. The advantage of Thickening is, however, that a larger free Distance between the arcuate middle part and the thickened end of the free end 26 is possible. This can be favorable from a manufacturing point of view, if at the single bending the spring steel of the tension clamp strong springs back and it therefore due to geometric Restrictions are not possible, the free ends as far as the approximate arcuate central part that a chaining can be prevented.

Die Fig. 5a und 5b zeigen schließlich eine andere, nicht unter die vorliegende Erfindung fallende 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.Finally, FIGS. 5a and 5b show another, not covered by the present invention Embodiment, the inner leg is not through a arcuate central part are interconnected. Instead of there are no free ends 26 before, but is the Clamping clamp made in this area throughout. In spite of the quite different acting arrangement of the ends relative to the traversing areas evolves However, the same basic geometry, according to the free distance between the present in the case of the inner legs 12th arranged free ends and the continuous loop 30th formed free distance also be chosen so small must be that a 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 1a bis 1c dargestellten Ausführungsvariante, daß ebenfalls mit dieser dargestellten Geometrie kein Verhaken der beiden Spannklemmen mehr möglich ist.To clarify that with the proposed clamps a mutual engagement of the loop of a tension clamp in the loop of a similar clamp no longer is possible, the embodiment according to FIGS. 4a and 4b in Fig. 7 in a corresponding position being represented. Fig. 7 shows that due to the Thickenings 28.1 at the clamp 10.1 and 28.2 at the Clamp 10.2 no hooking of loops 16.1 and 16.2 more is possible. In the same way, the figures 6a and 6b with reference to those shown in Figures 1a to 1c Embodiment that also shown with this Geometry no hooking of the two clamps possible is.

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 tension clamps, the loops can be dimensioned correspondingly large, because the danger of a chaining of several clamps not longer exists. This gives the possibility to the To increase bending radii in the rail direction and the Torsionsanteil increase, so that the clamps a have improved spring characteristic. By the Extending the free ends in the context of reducing the free space can also be larger surface pressures achieve on the rail foot. This will be compared to known, also W-shaped clamping clamps at least the same technical characteristics, in particular in terms of elasticity in vertical and horizontal Direction and in the longitudinal and transverse direction to the rail generated. In addition, a simple and automatic Pre-installation of railway sleepers possible, on the other Side but also by providing parallel to each other extending inner leg one with as low as possible Effort feasible interchangeability both opposite Clamps of the same type as before already known, similarly shaped models.
