Abstract

A sound-damping rail assembly for a track for rail vehicles comprises a rail having a pair of downwardly converging flanks below its head and above its base. The rail is received in a frame with downwardly inclined sides, the flanks being braced against these sides by elastomeric layers which are interposed between the flanks and the sides. A further elastic layer can be provided between the base or foot of the rail and the inner supporting surface of the frame and such layers may completely envelop the rail except for the head.

Description

Die Erfindung betrifft eine elastisch gelagerte Schiene für Schienenfahrzeuge, die sich mit ihren unterhalb des Schienenkopfes befindlichen seitlichen Begrenzungsflächen über eine elastische Zwischenlage gegen die inneren seitlichen Begrenzungsflächen eines Rahmens abstützt. Derartige Schienen finden Verwendung bei der Straßenbahn, der U-Bahn, der Eisenbahn u. dgl.The invention relates to an elastically mounted rail for rail vehicles, which is supported with its lateral boundary surfaces located below the rail head via an elastic intermediate layer against the inner lateral boundary surfaces of a frame. Such rails are used in the tram, subway, railroad u. the like

Es ist bekannt, zur elastischen Lagerung einer Schiene für Schienenfahrzeuge unter dem Schienenfuß eine elastische Zwischenlage anzuordnen (DE-OS 27 45 220). Diese elastische Zwischenlage bewirkt jedoch keine bzw. nur eine sehr unbedeutende Schalldämmung.It is known to arrange an elastic intermediate layer for the elastic mounting of a rail for rail vehicles under the rail foot (DE-OS 27 45 220). However, this elastic intermediate layer causes no or only very insignificant sound insulation.

Es ist ferner bekannt, gemäß Oberbegriff des Anspruch 1, zur elastischen Lagerung einer Schiene für Schienenfahrzeuge eine elastische Zwischenlage unter dem Schienenkopf anzuordnen (GB-PS 1 155 075). Auch diese Schienenlagerung bewirkt nur eine äußerst geringe Schalldämmung, weil die elastische Zwischenlage, ebenso wie bei der vorgenannten unter dem Schienenfuß angeordneten elastischen Zwischenlage, vorwiegend nur auf Druck beansprucht wird. Darüber hinaus erfordert diese Schienenlagerung eine verhhältnismäßig große Bauhöhe.It is also known, according to the preamble of claim 1, to arrange an elastic intermediate layer under the rail head for the elastic mounting of a rail for rail vehicles (GB-PS 1 155 075). This rail mounting also results in an extremely low level of sound insulation, because the elastic intermediate layer, as in the case of the above-mentioned elastic intermediate layer arranged under the rail base, is predominantly only subjected to pressure. In addition, this rail storage requires a relatively large height.

Bei einter weiteren elastisch gelagerten Schiene ist sowohl unter dem Schienenfuß als auch unter dem Schienenkopf eine elastische Zwischenlage angeordnet (US-PS 2 045 253). Diese Schienenlagerung weist die Nachteile beider vorgenannter Schienenlagerungen auf.In the case of another further elastically mounted rail, an elastic intermediate layer is arranged both under the rail foot and under the rail head (US Pat. No. 2,045,253). This rail bearing has the disadvantages of both of the aforementioned rail bearings.

Es werden daher üblicherweise unter den die Schienen tragenden Schwellen Metallplatten o. dgl. schalldämmende Lager angeordnet. Bei einem derartigen Lager stützen sich die die Schienen tragenden Schwellen o. dgl. über an deren Umfang angeordnete schräg gestellte elastische Zwischenlagen gegen mit dem Fundament verbundene Lagerrahmen ab (DE-OS 28 28 713). Die schräg gestellten elastischen Zwischenlagen werden nur zu einem Teil auf Druck, zu einem Teil aber auch auf Schub beansprucht. Da hierdurch eine gute Schalldämmung bewirkt wird, haben sich diese Lager bestens bewährt; sie können aber nicht immer eingesetzt werden, weil der für die Lager erforderliche Raum nicht überall zur Verfügung steht.It is therefore usually arranged under the sleepers supporting the rails, metal plates or the like. Sound-absorbing bearings. In such a bearing, the sleepers supporting the rails or the like are supported against bearing frames connected to the foundation by means of inclined elastic intermediate layers arranged on their circumference (DE-OS 28 28 713). The inclined elastic intermediate layers are only partially subjected to pressure, but also partially to thrust. Since this provides good sound insulation, these bearings have proven their worth; however, they cannot always be used because the space required for the storage is not available everywhere.

Der Erfindung liegt die Aufgabe zugrunde, die Schiene derart elastisch zu lagern, daß möglichst große Federwege möglich sind, so daß eine weitgehende Dämmung sowohl des Körperschalls als auch des Luftschalls erreicht wird, und daß sie nur wenig Raum erfordert, so daß die Schiene sowohl als im Straßenniveau verlegte Straßenbahnschiene Verwendung finden als auch in Tunneln eingesetzt werden kann.The invention has for its object to support the rail so elastic that the largest possible spring travel is possible, so that extensive insulation of both structure-borne noise and airborne sound is achieved, and that it requires little space, so that the rail both tram rails laid at street level can also be used in tunnels.

Die Lösung der gestellten Aufgabe besteht darin, daß bei einer elastisch gelagerten Schiene der eingangs genannten Art, in dem Bereich, in dem die abstützung über die elastische Zwischenlage erfolgt, sich sowohl die die Schiene unterhalb des Schienenkopfes seitlich begrenzenden Flächen als auch die inneren seitlichen Begrenzungsflächen des Rahmens geradlinig nach unten verjüngen, und daß die Schiene derart innerhalb des Rahmens angeordnet ist, daß keine Berührung zwischen der Schiene un dem Rahmen stattfinden kann.The solution to the problem is that with an elastically mounted rail of the type mentioned, in the area in which the support is provided via the elastic intermediate layer, both the surfaces laterally delimiting the rail below the rail head and the inner lateral delimiting surfaces of the frame taper straight down and that the rail is arranged within the frame such that no contact between the rail and the frame can take place.

Die gemäß der Erfindung elastisch gelagerte Schiene erfordert eine Bauhöhe, die nur geringfügig größer ist als die Höhe der Schiene selbst. Sie ist daher insbesondere auch zur Sanierung von vorhandenen Strecken - mit oder ohne Schotter - geeignet. Außerdem hat sich gezeigt, daß bei einer gemäß der Erfindung gelagerten Schiene weniger Verschleiß an der Schiene und am Fahrzeugrad sowie eine geringere riffelung der Schie» nenlauffläche auftreten. Darüber hinaus entfallen die üblichen Klemmen für die Befestigung der Schiene.The rail mounted elastically according to the invention requires an overall height which is only slightly greater than the height of the rail itself. It is therefore particularly suitable for the rehabilitation of existing lines - with or without ballast. In addition, it has been found that less wear to the rail and on the vehicle wheel and a lower corrugation of the pushing "nenlauffläche occur in a bearing according to the invention rail. In addition, the usual clamps for fastening the rail are omitted.

In Ausgestaltung der Erindung ist zwischen dem Schienenfuß und der inneren unteren Begrenzungsfläche des Rahmens eine weitere elastische Zwischenlage vorgesehen, so daß bei einer bestimmten Belastung der Schiene die Federung progressiv verläuft und außerdem keine Berührung zwischen der Schiene und der inneren untern Begrenzungsfläche des Rahmens stattfinden kann.In an embodiment of the invention, a further elastic intermediate layer is provided between the rail foot and the inner lower boundary surface of the frame, so that the suspension runs progressively under a certain load on the rail and, moreover, no contact can take place between the rail and the inner lower boundary surface of the frame.

Vorteilhafterweise ist die Schiene, mit Ausnahme des Schienenkopfes, vollständig von elastischen Zwischenlagen umhüllt. Hierdurch wird außer der besseren Schalldämmung eine Isolierung der Schiene erreicht.With the exception of the rail head, the rail is advantageously completely covered by elastic intermediate layers. As a result, in addition to better sound insulation, the rail is insulated.

Nach einer anderen vorteilhaften Ausgestaltung der Erfindung ist der Winkel, den die seitlichen Begrenzungsflächen des sich verjüngenden Bereichs der Schiene miteinander bilden, kleiner als derjenige Winkel, den die inneren seitlichen Begrenzungsflächen des Rahmens miteinander bilden.According to another advantageous embodiment of the invention, the angle which the lateral boundary surfaces of the tapering region of the rail form with one another is smaller than the angle which the inner lateral boundary surfaces of the frame form with one another.

In weiterer Ausgestaltung der Erfindung ist zwischen der unter dem Schienenfuß angeordneten elastischen Zwischenlage und der inneren unteren Begrenzungsfläche des Rahmens mindestens ein Zwischenraum vorgesehen, dessen Höhe und dessen Querschnitt so bemessen sind, daß bei Überschreitung der Normalbelastung der Schiene - die durch ein normal beladenes Schienenfahrzeug ausgeübt wird - der Zwischenraum von der elastischen Zwischenlage völlig ausgefüllt ist. Die Normalbelastung beträgt dabei etwa 70% bis 80% der Vollast. Durch dieses Merkmal der Erfindung ist die Federung bei leeren bis normal beladenen Fahrzeugen verhältnismäßig weich, während sie bei einer höheren Belastung sehr schnell härter wird. Dadurch wird bei einer Belastung der Schiene durch lere bis normal beladene Fahrzeuge eine optimale Schalldämmung erreicht.In a further embodiment of the invention, at least one intermediate space is provided between the elastic intermediate layer arranged under the rail foot and the inner lower boundary surface of the frame, the height and cross section of which are dimensioned such that when the normal load on the rail is exceeded, which is exerted by a normally loaded rail vehicle - the space is completely filled by the elastic liner. The normal load is about 70% to 80% of full load. With this feature of the invention, the suspension is relatively soft in empty to normally loaded vehicles, while it becomes very hard at higher loads. In this way, optimal sound insulation is achieved when the rail is loaded by empty to normally loaded vehicles.

Um ein Herauswandern des die elastischen Einlagen bildenden Werkstoffs, wie beispielsweise Gummi, zu verhindern, weisen die elastischen Zwischenlagen mindestens eine Einlage aus Metall, Gewebe o. dgl. auf.In order to prevent the material forming the elastic inserts, such as rubber, from migrating out, the elastic intermediate layers have at least one insert made of metal, fabric or the like.

die elastischen Zwischenlagen sind zweckmäßi-the elastic intermediate layers are

gerweise so bemessen, daß sie auch bei unbelasteter Schiene unter Vorspannung stehen.dimensioned in such a way that they are under tension even when the rail is not loaded.

Um auch genormte Schienen gemäß der Erfindung elastisch lagern zu können, ist in Weiterbildung der Erfindung der sich nach unten verjüngende Bereich der Schiene durch Formteile gebildet, deren innere Begrenzungsflächen der genormten Schiene angepaßt sind.In order to be able to elastically support standardized rails according to the invention, in a further development of the invention the downwardly tapering region of the rail is formed by molded parts, the inner boundary surfaces of which are adapted to the standardized rail.

Die erfindungsgemäß gelagerte Schiene kann so gestaltet sein, daß zwischen dem sich nach unten verjüngenden Bereich der Schiene und dem Schienenfuß ein Steg mit etwa parallelen Begrenzungsflächen vorgesehen ist oder daß die Formteile sich über die gesamte Höhe des Steges der genormten Schiene erstrecken.The rail mounted according to the invention can be designed such that a web with approximately parallel boundary surfaces is provided between the downwardly tapering region of the rail and the rail base, or that the molded parts extend over the entire height of the web of the standardized rail.

Der Zusammenbau der elastisch gelagerten Schiene wird dadurch erleichtert, daß der Rahmen durch zwei metallene Hälften gebildet ist, die durch Schrauben zusammengehalten sind.The assembly of the elastically mounted rail is facilitated in that the frame is formed by two metal halves which are held together by screws.

Bei einer bevorzugten Ausführungsform der Erfindung sind die Berührungsflächen des Rahmens derart abgeschrägt, daß sie einen nach oben offenen keilförmigen Spalt bilden. Dadurch kann durch entsprechendes Spannen der die beiden Hälften des Rahmens zusammenhaltenden Schrauben die gewünschte Vorspannung der elastischen Einlagen sehr genau eingestellt werden.In a preferred embodiment of the invention, the contact surfaces of the frame are chamfered in such a way that they form an upwardly open wedge-shaped gap. As a result, the desired pretensioning of the elastic inserts can be set very precisely by appropriately tightening the screws holding the two halves of the frame together.

The contact surfaces 6.3 of the frame 6 are beveled and thereby form an upwardly open gap 6.4. In its lower area, the frame 6 has flange-like lugs 6.5. An intermediate space 10 with a height H1 is provided between the elastic intermediate layer 7 arranged under the rail foot 4 and the inner lower boundary surface 6.2 of the frame 6.

Bei der in Fig. 2 dargestellten Schiene entsprechen der Schienenkopf 11 und der Steg 13 einer genormten Schiene, während der Schienenfuß 14 schmaler als bei einer genormten Schiene ist.
