Abstract

1. Rail bearing, which attenuates soudn conducted through solids, for rail vehicles, in which the rails rest on sleepers, metal plates or the like, which bear by way of elastic intermediate layers, such as rubber plates, rubber-to-metal bearing or the like, which are arranged set obliquely at their circumference, against bearing frames connected with the foundation, and where in a further elastic intermediate layer is arranged underneath the sleepers or the like and rests against either only the sleepers or the like or only the foundation so that a spacing is present between either the further elastic intermediate layer and the sleepers or the like or between the further elastic intermediate layer and the foundation, characterised thereby, that the obliquely set elastic intermediate layers (3) are so dimensioned that their maximum stroke is achieved already on normal loading of the rail bearing, which is exerted by a normally laden rail vehicle, and that either the spacing (A2) between the further elastic intermediate layer (6) and the sleepers (2) or the spacing (A4) between the further elastic intermediate layer (6) and the foundation (4) is so dimensioned that it assumes the zero value on reacting the normal loading of the rail bearing, so that the further elastic intermediate layer (6) contributes to the support of the sleepers or the like already when a rail vehicle with slightly greater than the normal loading travels over the rail bearing.

Description

Die Erfindung betrifft ein körperschalldämmendes Schienenlager für Schienenfahrzeuge, bei dem die Schienen auf Schwellen, Metallplatten o. dgl. ruhen, die sich über an deren Umfang angeordnete schräg ge­stellte elastische Zwischenlagen, wie Gummiplatten, Gummi-Metall-Lager o. dgl.,gegen mit dem Fundament verbundene Lagerrahmen abstützen, und bei dem unterhalb der Schwellen o. dgl. eine weitere elastische Zwischen­lage angeordnet ist, die nur an den Schwellen o. dgl. oder nur an dem Fundament anliegt, so daß zwischen der weiteren elastischen Zwischenlage und den Schwellen o. dgl. bzw. zwischen der weiteren elastischen Zwischen­lage und dem Fundament ein Abstand vorhanden ist.The invention relates to a structure-borne sound-absorbing rail bearing for rail vehicles, in which the rails rest on sleepers, metal plates or the like, which are arranged against inclined elastic intermediate layers, such as rubber plates, rubber-metal bearings or the like, arranged on their circumference support the frame connected to the foundation, and in which a further elastic intermediate layer is arranged below the sleepers or the like, which rests only on the sleepers or the like or only on the foundation, so that o. between the further elastic intermediate layer and the sleepers . Like. Or there is a distance between the further elastic intermediate layer and the foundation.

Körperschalldämmende Schienenlager der vorgenannten Art (vgl. z. B. DE-OS 28 28 713) sind so gestaltet, daß ihre maximale Einfederung bei Vollast erreicht wird. Bei steigender Belastung des Schienenlagers verringert sich der Abstand zwischen der weiteren elastischen Zwischenlage und den Schwellen o. dgl. bzw. zwischen der weiteren elastischen Zwischenlage und dem Funda­ment immer mehr und nimmt schließlich - bei Erreichen der Vollast - den Wert Null an. Erst bei Überschreiten der Vollast tritt die weitere elastische Zwischenlage in Funktion; sie dient also gewissermaßen als Notan­schlag, der eine Beschädigung des Schienenlagers bei etwaiger Überschreitung der Vollast verhindert. Da jedoch bei etwa 95 % des täglichen Verkehrs die Be­lastung unterhalb der Vollast liegt, ist während dieser Zeit die Körperschalldämmung nicht optimal. Die wäh­rend der genannten 95 % des täglichen Verkehrs auf­tretende Durchschnittsbelastung, die als Normal­ belastung bezeichnet wird, beträgt etwa 70 bis 80 % der Vollast. Gerade während der verkehrsruhigeren Zeiten wäre aber eine besonders gute Körperschall­dämmung zweckmäßig, weil bei geringerer Inanspruch­nahme des Schienenverkehrs auch der Straßenverkehr geringer ist und somit der auf den Straßenverkehr zurückzuführende Geräuschpegel erheblich niedriger ist als während der Hauptverkehrszeiten. Je niedriger nämlich der vom Straßenverkehr ausgehende Geräusch­pegel ist um so stärker wirkt sich der von den Schienen­fahrzeugen ausgehende Körperschall aus.Structure-borne sound-absorbing rail bearings of the aforementioned type (see, for example, DE-OS 28 28 713) are designed so that their maximum deflection is achieved at full load. With increasing load on the rail bearing, the distance between the further elastic intermediate layer and the sleepers or the like or between the further elastic intermediate layer and the foundation decreases more and more and finally - when the full load is reached - assumes the value zero. Only when the full load is exceeded does the further elastic intermediate layer function; it serves as a kind of emergency stop, which prevents damage to the rail bearing if the full load is exceeded. However, since the load is below full load in around 95% of daily traffic, the structure-borne noise insulation is not optimal during this time. The average load occurring during the mentioned 95% of daily traffic, which is considered normal load is about 70 to 80% of full load. Particularly during quieter times, a particularly good structure-borne noise insulation would be advisable, because with less use of rail traffic, road traffic is also lower and the noise level due to road traffic is therefore considerably lower than during rush hour. The lower the noise level from road traffic, the stronger the structure-borne noise emitted by the rail vehicles.

Der Erfindung liegt daher die Aufgabe zugrunde, das Schienenlager der genannten Art so auszubilden, daß eine optimale Körperschalldämmung bei Normalbelastung des Schienenlagers erreicht wird.The invention is therefore based on the object of designing the rail bearing of the type mentioned in such a way that optimum structure-borne sound insulation is achieved with normal loading of the rail bearing.

Die Lösung der gestellten Aufgabe besteht darin, daß die schräg gestellten elastischen Zwischenlagen so bemessen sind, daß ihre maximale Einfederung bereits bei Normalbelastung des Schienenlagers - die durch ein normal beladenes Schienenfahrzeug ausgeübt wird - erreicht wird, und daß der Abstand zwischen der weite­ren elastischen Zwischenlage und den Schwellen bzw. der Abstand zwischen der weiteren elastischen Zwischenlage und dem Fundament so bemessen ist, daß er bei Erreichen der Normalbelastung des Schienenlagers den Wert Null annimmt, so daß die weitere elastische Zwischenlage schon dann zur Abstützung der Schwellen o.dgl. bei­trägt, wenn ein Schienenfahrzeug mit einer geringfügig höheren als der normalen Beladung über das Schienen­lager fährt.The solution to the problem is that the inclined elastic intermediate layers are dimensioned such that their maximum deflection is achieved even with normal loading of the rail bearing - which is exercised by a normally loaded rail vehicle - and that the distance between the further elastic intermediate layer and the thresholds or the distance between the further elastic intermediate layer and the foundation is dimensioned such that it assumes the value zero when the normal load of the rail bearing is reached, so that the further elastic intermediate layer or the like is then already used to support the sleepers. contributes when a rail vehicle with a slightly higher than normal load passes over the rail bearing.

Damit bei Überschreitung der Normalbeladung der Schienen­fahrzeuge ein allmählicher Übergang von der weicheren - durch die schräg gestellten elastischen Zwischenlager gebildete - auf die härtere - durch die weitere elastische Zwischenlage gebildete - Feder erfolgt, ist in Ausgestaltung der Erfindung die Weitere elastische Zwischenlage mit Ausnehmungen versehen.So that when the normal load of the rail vehicles is exceeded, there is a gradual transition from the softer spring - formed by the inclined elastic intermediate bearing - to the harder spring - formed by the further elastic intermediate layer, the further elastic intermediate layer is provided with recesses.

Statt der Ausnehmungen kann die weitere elastische Zwischenschicht auch mit Rippen, Wülsten o. dgl. ver­sehen sein, wobei in weiterer Ausgestaltung der Erfin­dung die Wülste kegel- oder pyramidenförmig ausge­bildet sind.Instead of the recesses, the further elastic intermediate layer can also be provided with ribs, beads or the like, the beads being conical or pyramid-shaped in a further embodiment of the invention.

In der Zeichnung sind zwei Ausführungsbeispiele der Er­findung jeweils im Querschnitt dargestellt. Es zeigen:

  • Fig. 1 ein Schienenlager, bei dem auf dem Fundament eine weitere elastische Zwischenlage angeordnet ist;
  • Fig. 2 ein Schienenlager, bei dem unter der Schwelle eine weitere elastische Zwischenlage angeordnet ist.
In the drawing, two embodiments of the invention are each shown in cross section. Show it:

Eine weitere elastische Zwischenlage 6 ist auf dem Fundament 4 angeordnet, derart, daß zwischen der Schwelle 2 und der Oberfläche der elastischen Zwischenlage 6 ein Abstand A2 verbleibt. Die weitere elastische Zwischen­lage 6 ist an ihrer Oberseite mit Ausnehmungen 7 ver­sehen.The rail bearing shown in Fig. 1 consists of a rail 1 carrying, designed as a rib plate threshold 2, which is supported by inclined elastic intermediate layers 3 against the frame 4 connected to the foundation 4. Another elastic intermediate layer 6 is arranged on the foundation 4 such that a distance A2 remains between the threshold 2 and the surface of the elastic intermediate layer 6. The further elastic intermediate layer 6 is provided with recesses 7 on its upper side.

Bei dem in Fig. 2 dargestellten Schienenlager ist eine weitere elastische Zwischenlage 6 an der Unterseite der Schwelle 2 befestigt. An der elastischen Zwischenlage 6 sind Wülste 8 vorgesehen, die kegel- oder pyramiden­förmig ausgebildet sind. Die Wülste 8 der elastischen Zwischenlage 6 haben vom Fundament 4 einen Abstand A4.In the rail bearing shown in FIG. 2, a further elastic intermediate layer 6 is attached to the underside of the sleeper 2. On the elastic intermediate layer 6 beads 8 are provided, which are conical or pyramid-shaped. The beads 8 of the elastic intermediate layer 6 are at a distance A4 from the foundation 4.
