Hierzu umfasst die Lagerung ein Federsystem mit einer Gesamtkennlinie mit geknicktem Verlauf derart, dass bei auf das Federsystem eingeleiteter Kraft, die kleiner als die im Arbeitsbereich wirkenden Kräfte ist, die Kennlinie steil ansteigt und im Arbeitsbereich flach verläuft. Hierzu können sowohl bodenseitig als auch oberseitig entlang der Unterlage Federelemente verlaufen, die im erforderlichen Umfang vorgespannt werden, um die gewünschte geknickte Kennlinie zu erzielen.From EP 0 666 938 B a storage for a shell is known, depending on considered optimal conditions from the introduced forces of elasticity adjust, inter alia, when passing through rail vehicles elasticity is given, which allows a strong damping. For this purpose, the storage comprises a spring system with an overall characteristic with kinked course such that when on the spring system introduced force which is smaller than the forces acting in the work area, the Characteristic increases steeply and runs flat in the work area.

Der EP 0 545 123 B1 ist eine Schienenbefestigungsanordnung zu entnehmen, bei der eine Rippenplatte in einer Zwischenplatte einvulkanisiert ist, die ihrerseits eine wannenförmige Einlage aufweist, die sich unterhalb der Schienenbefestigungsplatte erstreckt. Die Zwischenlage selbst wird über Befestigungselemente vorgespannt lagefixiert.EP 0 545 123 B1 discloses a rail fastening arrangement in which a Ribbed plate is vulcanized in an intermediate plate, which in turn a trough-shaped Insert has, which extends below the rail mounting plate. The liner itself is fixed in position by means of fastening elements.
Nach der EP 0 546 363 B ist eine Unterlage auf einer elastischen Zwischenlage abgestützt, deren Federsteifigkeit derart aufstandskraftabhängig veränderbar ist, dass die Gesamtauflagefläche der Zwischenlage mit zunehmendem Winkel α ausgehend von der Mittelachse eines Schienenabschnitts kontinuierlich zunimmt.According to EP 0 546 363 B, a pad is supported on an elastic intermediate layer, whose spring stiffness is changeable depending on the uprising force, that the total support surface the intermediate layer with increasing angle α, starting from the central axis of a Rail section continuously increases.
Aus der DE 44 41 561 A1 ist ein schalldämmendes Schienenlager bekannt, das eine asymmetrisch ausgebildete Leistenplatte zur Aufnahme eines Schienenfußes sowie eine Elastomer-Zwischenplatte umfasst, über die die Leistenplatte abgestützt ist. Außerhalb der Schiene verläuft die Leistenplatte mit der Zwischenplatte beabstandet zu einer Abstützung. Bei unzulässiger Neigung der Schiene stützt sich die Zwischenplatte mit der Leistenplatte auf der Unterlage ab, um die Kippbewegung zu begrenzen.From DE 44 41 561 A1 a sound-insulating rail bearing is known, which is an asymmetric trained strip board for receiving a rail foot and an elastomer intermediate plate includes, over which the last board is supported. Outside the rail the strip board runs with the intermediate plate spaced to a support. at Inadmissible inclination of the rail supports the intermediate plate with the last plate on the Pad to limit the tilting movement.
Die EP 0 236 703 A2 bezieht sich auf ein Körperschall dämmendes Schienenlager, bei dem eine Schwelle über elastische Zwischenlager in einem Rahmen gelagert ist. Unterhalb der Schwelle ist eine elastische Zwischenlage vorhanden, die beabstandet zu einem Fundament verläuft. Werden zulässige Krafteinleitungen überschritten, stützt sich die Schwelle über die Zwischenlage auf dem Fundament ab. Die Zwischenlage selbst weist zur Beeinflussung deren Federsteifigkeit Ausnehmungen bzw. Vorsprünge auf.EP 0 236 703 A2 relates to a structure-borne sound insulating rail bearing in which a threshold via elastic intermediate storage is stored in a frame. Below the Threshold is present an elastic intermediate layer which is spaced from a foundation runs. If permissible force transmissions are exceeded, the threshold is based on the Liner on the foundation from. The intermediate layer itself has to influence their Spring stiffness recesses or projections on.
Der vorliegenden Erfindung liegt das Problem zugrunde, eine Lagerung der eingangs genannten Art so auszubilden, dass unzulässige Belastungen der Unterlageplatten nicht zu einer Beschädigung dieser führen, ohne dass bei üblichen Krafteinleitungen die gewünschten Federeigenschaften der Zwischenlagen verlassen werden.The present invention is based on the problem, a storage of the above mentioned type in such a way that impermissible loads on the pads do not Damage this lead without the usual force discharges the desired Leave spring properties of the liners.
Erfindungsgemäß wird das Problem dadurch gelöst, dass das flächige Zwischenelement eigensteif ist und aus Metall oder Kunststoff besteht und dass das Zwischenelement mit seiner Längsachse in Längsrichtung der Unterlageplatte und innerhalb oder im Wesentlichen innerhalb in Richtung der Abstützung verlaufender vertikaler Projektion des Schienenabschnittes verläuft.According to the invention, the problem is solved in that the flat Interstitial element is eigensteif and is made of metal or plastic and that the intermediate element with its longitudinal axis in the longitudinal direction of the pad plate and inside or essentially in the direction of the support extending vertical projection of the Rail section runs.
Erfindungsgemäß wird die Steifigkeit der Unterlageplatte bei unzulässigen Krafteinleitungen in diese dadurch erhöht, dass eine Abstützung über die eine geringe Elastizität aufweisendes flächiges Zwischenelement wie Metallplatte erfolgt, so dass ein weiteres Verformen der Unterlageplatte, welches ansonsten aufgrund der Elastizität der Zwischenlage möglich wäre, unterbunden wird. Dabei kann das Zwischenelement integraler Bestandteil der Unterlageplatte sein. Vorzugsweise ist jedoch das Zwischenelement in das Zwischenlagenmaterial teilweise einvulkanisiert, so dass zwischen dem Zwischenelement und der Unterlageplatte eine elastische Schicht verläuft.According to the invention, the rigidity of the base plate in case of impermissible introduction of force increased in this fact that a support on the low elasticity exhibiting flat intermediate element such as metal plate takes place, so that further deformation of the Underlay plate, which would otherwise be possible due to the elasticity of the intermediate layer, is prevented. In this case, the intermediate element integral part of the pad be. Preferably, however, the intermediate element is partially in the interlayer material vulcanized, so that between the intermediate element and the base plate a elastic layer runs.
Bei dem Zwischenelement handelt es sich erwähntermaßen vorzugsweise um ein Plattenelement wie Blechplatte, deren Längsachse in Längsrichtung der Unterlageplatte verlaufen sollte. Dabei sollte das Plattenelement eine Breite von in etwa 20 bis 40 mm, eine Länge von in etwa 200 bis 300 mm und eine Dicke von in etwa 5 bis 15 mm aufweisen.The intermediate element is, as mentioned, preferably a plate element as sheet metal plate whose longitudinal axis extending in the longitudinal direction of the pad plate should. The plate element should have a width of about 20 to 40 mm, a length of in about 200 to 300 mm and a thickness of about 5 to 15 mm.
Bei unbelasteter Unterlageplatte sollte die freie Unterseite des Zwischenelementes zu der Fläche, die von den Bodenflächen der Vorsprünge aufgespannten Ebene einen Abstand von in etwa 3 bis 10 mm, insbesondere im Bereich von 5 mm aufweisen.When unloaded pad should the free bottom of the intermediate element to the Surface, the plane spanned by the bottom surfaces of the projections spaced from in about 3 to 10 mm, in particular in the range of 5 mm.
Losgelöst hiervon können die Vorsprünge bodenflächenseitig gegebenenfalls Einlagen aufweisen, die bei üblichen Belastungen der Unterlageplatte unmittelbar die Steifigkeit der Zwischenlage beeinflussen.Detached from this, the projections on the floor surface side, where appropriate, deposits have, under normal loads of the pad plate directly the rigidity of the Influence liner.
Erstreckt sich das plattenförmige Zwischenelement innerhalb der Zwischenlage in dem Bereich, der innerhalb der senkrechten Projektion des von der Unterlagenplatte aufgenommenen Schienenabschnitts, also dessen Fuß verläuft, sollten die Vorsprünge in Längsrichtung der Unterlageplatte betrachtet außerhalb des Zwischenelements verlaufen, über die die Unterlageplatte bei üblichen Krafteinleitungen abgestützt ist. Dabei können die Vorsprünge in Draufsicht eine rechteckige Geometrie aufweisen. Ferner sollten mehrere, vorzugsweise sämtliche Vorsprünge innerhalb senkrechter Projektion vom jeweiligen Längsrand eines auf der Unterlageplatte angeordneten Schienenabschnitts verlaufen. Mit anderen Worten sollten die Vorsprünge von den senkrechten Projektionen der Längsränder geschnitten werden.The plate-shaped intermediate element extends within the intermediate layer in the Area that is within the vertical projection of the recorded from the backing plate Rail section, ie whose foot extends, the projections should be in the longitudinal direction of Underlay plate viewed outside the intermediate element, over which the pad plate is supported at normal force discharges. In this case, the projections in Top view have a rectangular geometry. Furthermore, several, preferably all projections within vertical projection from the respective longitudinal edge of a run the pad plate arranged rail section. In other words, should the projections are cut from the vertical projections of the longitudinal edges.
Des Weiteren zeichnet sich nach einen vorteilhaften weiterbildung eine Unterlageplatte der zuvor beschriebenen Art mit zumindest zwei die Unterlageplatte sowie die Zwischenlage durchsetzenden Hülsen, die ihrerseits von jeweils einem Befestigungselement wie Bolzen zum Lagefixieren der Unterlageplatte auf der Abstützung und zum gegebenenfalls Vorspannen der Zwischenlage durchsetzbar sind, dadurch aus, dass die Hülse ein lösbar mit dieser verbundenes ringförmiges Flanschelement als Auflage auf die Abstützung aufweist, zu dem die Zwischenlage beabstandet verläuft. Dabei sollte die Hülse abstützungsseitig Vorsprünge aufweisen, die in Aufnahmen des Flanschelementes zum Fixieren dieses verlaufen.Furthermore, according to an advantageous further development of a pad plate of the type described above with at least two the pad plate and the intermediate layer passing sleeves, in turn, each of a fastener such as bolts to Fixing the base plate on the support and possibly biasing the Interposition can be enforced, characterized in that the sleeve releasably connected thereto having annular flange element as a support on the support, to which the Interposed spacer runs. The sleeve should support projections on the support side have, which extend in recordings of the flange to fix this.
Durch diese Maßnahmen ist sichergestellt, dass das Flanschelement, über das die Hülse und damit die Lagerung auf einer Abstützung abstützbar und im erforderlichen Umfang die Zwischenlage bzw. die entlang der Oberseite der Unterlageplatte verlaufenden weiteren Federelemente vorspannbar sind, zu einer Beeinflussung der Steifigkeit der Zwischenlage nicht führt, da ein unmittelbarer Kontakt zwischen der Zwischenlage und dem Flanschelement bei üblichen Krafteinleitungen in die Unterlageplatte nicht erfolgt. Mit anderen Worten führt das Flanschelement nicht zu einer Reduzierung der Steifigkeit der Zwischenlage.These measures ensure that the flange, over which the sleeve and so that the support can be supported on a support and to the required extent the Liner or along the top of the pad plate extending further Spring elements are biased to influence the rigidity of the intermediate layer does not lead, since a direct contact between the intermediate layer and the flange element does not occur at normal force transmission into the pad. In other words leads the flange element does not reduce the rigidity of the intermediate layer.

Gleisoberbaus dargestellt. Die Lagerung umfasst eine Schienenbefestigungsplatte wie Rippenplatte
10 und wird über nicht dargestellte Verbindungselemente wie Bolzen mit einer
Abstützung wie zum Beispiel Betonplatte verbunden. Die Rippenplatte 10 ist umfangs- und
bodenseitig von einer elastischen Zwischenlage 12 umgeben, wobei die Rippenplatte 10 mit
der Zwischenlage 12 insbesondere durch Vulkanisieren verbunden wird. Die Zwischenlage
12 weist einen umlaufenden Rand 14 sowie im Ausführungsbeispiel in zwei Gruppen von
Trippeln angeordnete Vorsprünge 16, 18, 20 bzw. 22, 24, 26 auf, deren abstützungsseitigen
Bodenflächen 28, 30, 32, 34 in einer Ebene verlaufen, in der der umlaufende Rand 14 mit
seinem freien Ende verläuft. Gegebenenfalls können -wie die Fig. 2 und 3 verdeutlichen- in
den Bodenflächen 28, 30, 32, 34 flächige Einlagen 36, 38, 40, 42 einvulkanisiert werden, um
die gewünschte Steifigkeit der Vorsprünge 16, 18, 20, 22, 24, 26 und damit der Zwischenlage
12 gezielt einzustellen.In the figures, purely in principle is a storage for a track or rail section of a

22, 24, 26 zurückversetzt, wie die Schnittdarstellung gemäß Fig. 2 verdeutlicht. Dabei ist der
Abstand zwischen der Bodenfläche 46 der Einlage 44 zu den Bodenflächen 28, 30, 32, 34 der
Vorsprünge 16, 18, 20, 22, 24, 26 derart gewählt, dass bei üblichen Krafteinleitungen auf die
Rippenplatte 10 die Einlage 44 nicht auf der nicht dargestellten Abstützung aufliegt, also die
Steifigkeit der Zwischenlage 12 nicht beeinflusst. Erst wenn unzulässige Krafteinleitungen
auftreten, wird die Rippenplatte 10 über die Einlage 44 abgestützt, so dass eine weitere
wesentliche Verformung ersterer nicht erfolgen kann. Es wird ein Durchbiegen vermieden,
wodurch andernfalls die Rippenplatte 10 beschädigt werden könnte. Dadurch, dass die
Einlage 44 im Bereich vertikaler Projektion der Schiene verläuft, wird diese optimal gesichert.Set back to the

die Breite in etwa 30 mm und die Dicke 10 mm betragen sollte. In Abhängigkeit von der
Länge der Rippenplatte 10 beläuft sich die Länge der Einlage 44 vorzugsweise im Bereich
zwischen 200 und 300 mm.The
Aus der Unteransicht gemäß Fig. 1 wird des Weiteren ersichtlich, dass die Vorsprünge 16,
18, 20 bzw. 22, 24, 26 in Längsrichtung der Rippenplatte 10 betrachtet außerhalb der
Längserstreckung der Einlage 44 verlaufen. Des Weiteren sollten die Gruppen von Vorsprüngen
16, 18, 20 bzw. 22, 24, 26 in Bezug auf die Rippenplatte 10 derart angeordnet sein,
dass erstere unterhalb der Längsränder eines auf der Rippenplatte 10 anzuordnenden Schienenabschnittes
verlaufen.From the bottom view according to FIG. 1, it can further be seen that the

können. Um den erforderlichen Ausschnitt in der Zwischenlage 12 beim Vulkanisieren zu
erzielen, wird die Hülse 48, 50 im abstützungsseitigen Ende von einem entsprechenden
