A base (6) of rubber or rubbery-elastic plastic is designed between a rail foot and a carrier plate (4). A sliding element (5) is formed between the outer boundary surface of pad and the inner boundary surface of the frame.

Description

Die Erfindung betrifft eine Vorrichtung zum Lagern von Schienen für Schienenfahrzeuge, wobei sich die Schienen mit ihren seitlichen Begrenzungsflächen über starre Zwischenlagen gegen die inneren Begrenzungsflächen eines starren Rahmens abstützen und wobei unterhalb der Schiene - mit Abstand von der unteren Begrenzungsfläche des Schienenfußes - eine Tragplatte angeordnet ist, auf die sich der Rahmen abstützt.The invention relates to a device for supporting rails for rail vehicles, wherein the rails are supported with their lateral boundary surfaces via rigid intermediate layers against the inner boundary surfaces of a rigid frame and wherein below the rail - at a distance from the lower boundary surface of the rail - a support plate is arranged on which the frame is based.

Das Befahren einer Schiene durch das Rad eines Schienenfahrzeugs ist punktuell gesehen das Einwirken einer Einzellast auf einen auf zwei Stützen ruhenden Träger, wobei das Rad die Einzellast und die Schiene den Träger darstellt. Im dynamischen Ablauf wird die Einzellast eine Linienlast, die vom Rad auf die Schiene einwirkt. Hierbei werden durch den Ablauf des Rades auf der Schiene Schwingungen erzeugt, deren Intensität abhängig ist von der Geschwindigkeit und den Unregelmäßigkeiten des Rades und der Schienenoberfläche. Diese Schwingungen werden sowohl auf das Rad als auch auf die Schiene übertragen. Die auf das rollende Rad einwirkenden Schwingungen werden durch das zwischen Achse und Schienenfahrzeug vorhandene Federsystem weitgehend gedämpft. Nachhaltiger sind allerdings die Einwirkungen der Schwingungen auf die Schiene. Die endlos verschweißte Schiene wirkt in dem gesamten in Schwingung versetzten Bereich als Resonanzkörper. Die punktuell ausgelösten Schwingungen werden in Längsrichtung der Schiene in die starre Schiene übertragen (Körperschall) und ferner durch die Schienenoberfläche an die Umwelt abgegeben (Luftschall).Driving a rail through the wheel of a rail vehicle is punctually seen the action of a single load on a resting on two supports carrier, wherein the wheel is the single load and the rail is the carrier. In the dynamic process, the single load becomes a line load that acts on the rail from the wheel. In this case, the course of the wheel on the rail generates vibrations whose intensity depends on the speed and the irregularities of the wheel and the rail surface. These vibrations are transmitted to both the wheel and the rail. The vibrations acting on the rolling wheel are largely attenuated by the existing between axle and rail vehicle spring system. More sustainable, however, are the effects of vibrations on the railways. The endless welded rail acts as a resonating body in the entire vibrated area. The selectively triggered vibrations are transmitted in the longitudinal direction of the rail in the rigid rail (structure-borne sound) and further discharged through the rail surface to the environment (airborne sound).

Darüber hinaus entstehen durch die rollende Bewegung des Rades am Schienenkopf Laufgeräusche. Die sich aufgrund von Luftschall und Laufgeräuschen ergebenden Auswirkungen auf die Umwelt sind sehr störend. Zur Minderung der die Umwelt beeinträchtigenden Auswirkungen des Luftschalls und der Laufgeräusche sind mehrere bekannte Maßnahmen möglich. Eine dieser bekannten Maßnahmen ist die elastische Lagerung der Schienen.In addition, caused by the rolling motion of the wheel on the rail head running noise. The effects on the environment due to airborne noise and noise are very disturbing. To reduce the environmental impact of airborne noise and running noise several known measures are possible. One of these known measures is the elastic mounting of the rails.

Bei einer der bekannten Vorrichtungen zum elastischen Lagern von Schienen für Schienenfahrzeuge sind beiderseits des Schienensteges und unterhalb des Schienenfußes Dämmelemente aus Gummi oder gummiähnlichem Werkstoff angeordnet ( DE 38 34 329 A1 ). Die Schiene ist somit sowohl in horizontaler als auch in vertikaler Richtung elastisch abgestützt.In one of the known devices for the elastic bearings of rails for rail vehicles both sides of the rail web and below the rail foot insulating elements made of rubber or rubber-like material are arranged ( DE 38 34 329 A1 ). The rail is thus elastically supported both in the horizontal and in the vertical direction.

Bei einer weiteren bekannten Vorrichtungen zum elastischen Lagern von Schienen für Schienenfahrzeuge stützt sich die Schiene mit den seitlichen Begrenzungsflächen des Schienensteges über elastische Zwischenlagen gegen die inneren seitlichen Begrenzungsflächen eines Rahmens ab ( DE 198 07 627 A1 ). Unterhalb des Schienenfußes kann ein Streifen aus elastischem Werkstoff vorgesehen sein, so dass auch in diesem Fall die Schiene sowohl in horizontaler als auch in vertikaler Richtung elastisch abgestützt ist.In another known devices for the elastic storage of rails for rail vehicles, the rail is supported with the lateral boundary surfaces of the rail web via elastic intermediate layers against the inner lateral boundary surfaces of a frame from ( DE 198 07 627 A1 ). Below the rail foot, a strip of elastic material may be provided, so that even in this case the rail is elastically supported both in the horizontal and in the vertical direction.

Die beiden vorgenannten bekannten Vorrichtungen weisen den Nachteil auf, dass die Schiene nicht nur in vertikaler Richtung Bewegungen ausführen kann, sondern auch in horizontaler Richtung quer zur Schienenlängsrichtung. Die Bewegungsmöglichkeit der Schiene in horizontaler Richtung ist jedoch nicht immer erwünscht. Der Erfindung liegt daher die Aufgabe zu Grunde, eine Vorrichtung zum Lagern von Schienen für Schienenfahrzeuge zu schaffen, die zwar eine horizontale Bewegung der Schiene zuläßt, die aber eine Bewegung der Schiene in horizontaler Richtung weitgehend verhindert.The two aforementioned known devices have the disadvantage that the rail can not only perform movements in the vertical direction, but also in the horizontal direction transverse to the rail longitudinal direction. However, the possibility of movement of the rail in the horizontal direction is not always desirable. The invention Therefore, the object is to provide a device for supporting rails for rail vehicles, although allowing a horizontal movement of the rail, but largely prevents movement of the rail in the horizontal direction.

Das Dokument DE 4 430 881 A offenbart eine Vorrichtung zum Lagern von Schienen mit den Merkmalen des Oberbegriffs des Anspruchs 1.The document DE 4 430 881 A discloses a device for supporting rails with the features of the preamble of claim 1.

Die Lösung der gestellten Aufgabe besteht bei einer Vorrichtung zum Lagern von Schienen für Schienenfahrzeuge der eingangs genannten Art mit den Merkmalen des Anspruchs 1 darin, dass die Zwischenlagen Starr sind und dass die äußeren Begrenzungsflächen der Zwischenlagen und die inneren Begrenzungsflächen des Rahmens geradlinig vertikal verlaufen.The solution of the problem consists in a device for supporting rails for rail vehicles of the type mentioned in the features of claim 1 is that the intermediate layers are rigid and that the outer boundary surfaces of the intermediate layers and the inner boundary surfaces of the frame are rectilinear vertical.

Während die Schiene in horizontaler Richtung - quer zur Schienenlängsrichung - völlig unbeweglich gegenüber der Tragplatte und damit auch gegenüber dem Unterbau ist, ermöglicht die zwischen dem Schienenfuß und der Tragplatte vorgesehene gummielastische Unterlage eine vertikale Bewegung der Schiene gegenüber der Tragplatte bzw. gegenüber dem Unterbau, wobei die gummielastische Unterlage gleichzeitig eine ausreichende Minderung der Auswirkungen des Luftschalls und der Laufgeräusche herbeiführt.While the rail in the horizontal direction - transverse to the rail longitudinal direction - completely immovable against the support plate and thus with respect to the substructure, provided between the rail and the support plate rubber-elastic pad allows vertical movement of the rail relative to the support plate or against the substructure, said the rubber-elastic pad at the same time causes a sufficient reduction of the effects of airborne noise and running noise.

In Ausgestaltung der Erfindung ist zwischen den äußeren Begrenzungsflächen der Zwischenlagen und den inneren Begrenzungsflächen des Rahmens mindestens ein Gleitelement angeordnet. Dadurch wird die vertikale Bewegung der Schiene gegenüber dem Unterbau wesentlich erleichtert.In an embodiment of the invention, at least one sliding element is arranged between the outer boundary surfaces of the intermediate layers and the inner boundary surfaces of the frame. This significantly facilitates the vertical movement of the rail relative to the base.

Zweckmäßigerweise ist das Gleitelement aus einem hoch gleitfähigen und hochverschleißfesten Kunststoff, vorzugsweise aus Polytetrafluorethylen (PTFE) gebildet. Der unter dem Handelsnamen Teflon bekannte Werkstoff PTFE besitzt besonders gute Gleiteigenschaften bei außergewöhnlich hoher Wärmebeständigkeit. Ferner trägt das erfindungsgemäße Gleitelement zur Minderung der Auswirkungen des Luftschalls und der Laufgeräusche bei.Conveniently, the slider is made of a highly lubricious and highly wear-resistant plastic, preferably made of polytetrafluoroethylene (PTFE). The PTFE material known under the trade name Teflon has particularly good sliding properties with exceptionally high heat resistance. Furthermore, the sliding element according to the invention contributes to reducing the effects of airborne noise and running noise.

Bei einer anderen Ausführungsform der Erfindung sind die Gleitelemente aus Gummi oder aus gummielastischem Kunststoff gebildet. Bei dieser Vorrichtung ist - innerhalb genau bestimmbarer Grenzen - auch eine geringe Bewegung der Schiene in horizontaler Richtung möglich. In diesem Falle ist es zweckmäßig, die den starren Zwischenlagen zugewandten Flächen der Gleitelemente besonders gleitfähig bzw. besonders glatt auszubilden oder mit einem Gleitmittel zu versehen.In another embodiment of the invention, the sliding elements are made of rubber or rubber-elastic plastic. In this device is - within exactly determinable limits - also a slight movement of the rail in the horizontal direction possible. In this case, it is expedient to form the surfaces of the sliding elements facing the rigid intermediate layers in a particularly slippery or particularly smooth manner or to provide them with a lubricant.

In weiterer Ausgestaltung der Erfindung erstreckt sich die zwischen dem Schienenfuß und der Tragplatte vorgesehene Unterlage über die gesamte Breite des Schienenfußes. Durch entsprechende Wahl des Werkstoffs und der Dicke der Unterlage kann eine passende Einfederung eingestellt werden.In a further embodiment of the invention, the provided between the rail and the support plate base extends over the entire width of the rail foot. By appropriate choice of material and the thickness of the pad a suitable deflection can be adjusted.

Die Erfindung kann noch dadurch verbessert werden, dass die zwischen dem Schienenfuß und der Tragplatte vorgesehene Unterlage aus einem Ring mit viereckigem Querschnitt besteht, der derart ausgebildet ist, dass seine äußeren und inneren Begrenzungsflächen sich geradlinig nach unten verjüngen und sich gegen konische Flächen der Unterlage und gegen ein unter dem Schienenfuß vorgesehenes konisches Auflageteil abstützen. Dadurch ist eine sehr genaue Bestimmung der Federkennlinie möglich.The invention can be further improved by the fact that provided between the rail and the support plate pad from a ring with quadrangular Cross-section is formed, which is formed such that its outer and inner boundary surfaces taper straight down and support against conical surfaces of the pad and against a provided under the rail foot conical rest part. As a result, a very accurate determination of the spring characteristic is possible.

Bei einer bevorzugten Ausführungsform der Erfindung ist zwischen den Seitenflächen der Schiene und den starren Zwischenlagen und/oder zwischen dem Fuß der Schiene und dem konischen Auflageteil mindestens eine Isolierfolie vorgesehen.In a preferred embodiment of the invention, at least one insulating film is provided between the side surfaces of the rail and the rigid intermediate layers and / or between the foot of the rail and the conical support part.
