B. aus Elastomeren wie Polyurethan-Elastomeren angeordnet ist, deren Federsteifigkeit sich in etwa flächenabhängig in Bezug auf die jeweilige wirksame Abstützfläche der Unterlageplatte auf die Zwischenplatte ändert.The invention relates to a bearing for a track section comprising running along the track section and receiving these under plates such Rail fastening or rib plates, with between the respective base plate and an associated intermediate support such as a threshold or concrete slab made of elastic material such as B. from elastomers such as polyurethane elastomers is arranged, the spring stiffness is approximately area-dependent with respect to the changes respective effective support surface of the base plate on the intermediate plate.
Um definierte Elastizitäten für den Eisenbauoberbau sicherzustellen und gleichzeitig eine Reduktion von Körperschall zu erzielen, werden elastische Zwischenplatten zwischen den das Gleis aufnehmenden Unterlageplatten wie Rippenplatten und der Abstützung wie Schwellen oder Betonplatten angeordnet, wobei eine Anwendung sowohl im Schotteroberbau als auch bei einer festen Fahrbahn erfolgt. Die zum Einsatz gelangenden elastischen Zwischenlagen bestehen aus zelligen Elastomeren wie PU-Schäumen, die eine Federsteifigkeit aufweisen, die in etwa linear abhängig zu der Auflagefläche der Unterlageplatte ist. Dies bedeutet, dass für Unterlageplatten mit voneinander abweichenden Abstützflächen Zwischenlagen unterschiedlicher Dicken zum Einsatz gelangen müssen, um im Gleis ein gleiches elastisches Verhalten zu erreichen, also gleiche Federsteifigkeiten in den jeweiligen Zwischenlagen vorliegen zu haben. To ensure defined elasticities for the iron superstructure and at the same time one To achieve structure-borne noise reduction, elastic intermediate plates are used between the base plates that hold the track, such as ribbed plates and the support arranged like sleepers or concrete slabs, with an application both in Ballast track as well as on a solid road. The ones used elastic intermediate layers consist of cellular elastomers such as PU foams, which have a spring stiffness that is approximately linearly dependent on the contact surface of the Base plate is. This means that for base plates with different ones Intermediate layers of different thicknesses are used must have the same elastic behavior in the track, i.e. the same To have spring stiffness in the respective intermediate layers.
Oberbaukonstruktionen mit elastischen Zwischenlagen sind z. B. der EP 0 666 938 B1
oder der DE 44 06 105 A1 zu entnehmen. Dabei können zur Lagerung der Unterlageplatten
Federsysteme mit einer Gesamtkennlinie mit geknicktem Verlauf derart zum
Einsatz gelangen, dass bei auf das Federsystem eingeleiteter Kraft, die kleiner als die im
Arbeitsbereich wirkende Kraft ist, die Kennlinie steil ansteigt und im Arbeitsbereich
flach verläuft.Superstructure constructions with elastic intermediate layers are e.g. B. EP 0 666 938 B1
or in
Aus der EP 0 546 363 ist eine Unterlage mit einer elastischen Zwischenlage bekannt, deren Federsteifigkeit derart aufstandskraftabhängig veränderbar ist, dass die gesamte Auflagefläche der Zwischenlage mit zunehmendem Winkel α ausgehend von der Mittelachse eines Schienenabschnittes kontinuierlich zunimmt.A base with an elastic intermediate layer is known from EP 0 546 363, whose spring stiffness can be changed depending on the contact force so that the entire Contact surface of the intermediate layer with increasing angle α starting from the The central axis of a rail section increases continuously.
Der vorliegenden Erfindung liegt das Problem zugrunde, eine Lagerung der eingangs genannten Art mit einer Zwischenplatte aus elastischem Material, deren Federsteifigkeit sich in Abhängigkeit von der auf die Zwischenlage einwirkenden wirksamen Abstützfläche der Unterlageplatte in etwa linearer Beziehung verändert, derart weiterzubilden, dass unabhängig von der Größe der Unterlageplatte gleich dimensionierte Zwischenlagen zum Einsatz gelangen können, ohne dass sich unterschiedliche Federsteifigkeiten ergeben.The present invention is based on the problem of storing the input mentioned type with an intermediate plate made of elastic material, the spring stiffness depending on the effective support surface acting on the intermediate layer the base plate changed in an approximately linear relationship, to further develop that regardless of the size of the base plate the same dimensioned intermediate layers can be used without different spring stiffness surrender.
