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, wie Straßenbahn, U-Bahn, Eisenbahn u. dgl..The invention relates to an elastically mounted rail for rail vehicles, such as trams, subways, trains and. Like ..

Es ist bekannt, zur elastischen Lagerung einer Schiene für Schienenfahrzeuge unter dem Schienenfuß eine elastische Zwischenlage anzuordnen. Diese elastische Zwischenlage bewirkt jedoch keine bzw. nur eine sehr unbedeutende Schalldämmung. Es werden daher üblicherweise unter den die Schienen tragenden Schwellen Metallplatten o. dgl. schalldämmende Lager angeordnet. Bei einem derartigen bekannten Lager stützen sich die die Schienen tragenden Schwellen o. dgl. über an deren Umfang angeordnete schräg gestellte Zwischenlagen gegen mit dem Fundament verbundenen Lagerrahmen ab (DE-OS 28 28 713). Diese Lager haben sich bestens bewährt; sie können aber nicht immer eingesetzt werden, weil der für die Lager erforderliche Raum nicht immer zur Verfügung steht.It is known to arrange an elastic intermediate layer for the elastic mounting of a rail for rail vehicles under the rail foot. However, this elastic intermediate layer causes no or only very insignificant sound insulation. It is therefore usually arranged under the sleepers supporting the rails, metal plates or the like. Sound-absorbing bearings. In such a known bearing, the sleepers supporting the rails or the like are supported against bearing frames connected to the foundation by means of inclined intermediate layers arranged on their circumference (DE-OS 28 28 713). These bearings have proven their worth; however, they cannot always be used because the space required for the storage is not always available.

Der Erfindung liegt die Aufgabe zugrunde, die Schiene selbst/elastisch zu lagern, daß sie bei weitgehender Dämmung sowohl des Körperschalls als auch des Luftschalls nur wenig Raum erfordert, so daß die elastisch gelagerte Schiene sowohl als im Straßenniveau verlegte Straßenbahnschiene Verwendung finden als auch in Tunneln eingesetzt werden kann.The invention has for its object to mount the rail itself / elastic that it requires little space with extensive insulation of both structure-borne noise and airborne sound, so that the elastically mounted rail can be used both as a tram rail laid at street level and in tunnels can be used.

Die Lösung der gestellten Aufgabe besteht darin, daß unterhalb des Schienenkopfes ein sich nach unten verjüngender Bereich vorgesehen ist, dessen seitliche Begrenzungsflächen sich über eine elastische Zwischenlage gegen einen Rahmen abstützen, dessen innere seitliche Begrenzungsflächen sich ebenfalls nach unten verjüngen.The solution to the problem is that below the rail head a downwardly tapering area is provided, the lateral boundary surfaces are an elastic intermediate support against a frame, the inner lateral boundary surfaces of which also taper downwards.

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 Strekken - 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 Schienenlauffläche auftreten. Darüber hinaus entfallen die üblichen Klemmen für die Befestigung der Schiene.The rail mounted elastically according to the invention requires a construction height that is only slightly greater than the height of the rail itself. It is therefore particularly suitable for the renovation of existing routes - with or without ballast. In addition, it has been found that less wear occurs on the rail and on the vehicle wheel and less corrugation of the rail running surface occurs in a rail mounted according to the invention. In addition, the usual clamps for fastening the rail are omitted.

In Ausgestaltung der Erfindung 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 unteren 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.The rail, with the exception of the rail head, is advantageously completely covered by elastic intermediate layers. As a result, in addition to better sound insulation, the rail is insulated.

Nach einem anderen Merkmal 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 feature of the invention, the angle which the lateral boundary surfaces of the tapered 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 leere 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. This ensures optimal sound insulation 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 zweckmäßigerweise so bemessen, daß sie auch bei unbelasteter Schiene unter Vorspannung stehen.The elastic intermediate layers are expediently dimensioned such 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 so that between the tapering downwards In the area of the rail and the rail foot, a web with approximately parallel boundary surfaces is provided 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. This can be achieved by appropriate tensioning. the two halves of the frame holding the screws, the desired preload of the elastic inserts can be set very precisely.

Zwischen dem Schienenfuß 4 und der inneren unteren Begrenzungsfläche 6.2 des Rahmens 6 ist eine weitere elastische Zwischenlage 7 vorgesehen. Die elastischen Zwischenlagen 5 und 7 weisen eine durch ein Gewebe gebildete Einlage 8 auf.The rail shown in FIG. 1 has, below the rail head 1, a region 2 which tapers downwards, to which a web 3 with approximately parallel boundary surfaces adjoins and which merges into the rail base 4.

The contact surfaces 6.3 of the frame 6 are chamfered and thereby form a gap 6.4 open at the top. 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.
