Description

Da aus Rillenschienen gebildete Gleise für Schienenfahrzeuge häufig im Erdreich verlegt werden, müssen sie mit einer elektrischen Isolierung ersehen sein. Die Erfindung betrifft eine derartige mit einer elektrischen Isolierung versehene, elastisch gelagerte Rillenschiene, wobei die Rillenschiene an ihren beiden Seiten und unter dem Schienenfuß mit einem isolierenden Werkstoff versehen ist und wobei die unter dem Schienenkopf etwa waagerecht verlaufenden Bereiche der elektrischen Isolierung mit Hohlräumen versehen sind. Der die elektrische Isolierung der Rillenschiene bewirkende Werkstoff bewirkt gleichzeitig eine Körperschalldämpfung.Since rails made of grooved rails for rail vehicles are often laid in the ground, they must be seen with electrical insulation. The invention relates to such provided with an electrical insulation, elastically mounted grooved rail, wherein the grooved rail is provided on both sides thereof and under the rail with an insulating material and wherein the under the rail head approximately horizontally extending portions of the electrical insulation are provided with cavities. The electrical insulation of the grooved rail causing material simultaneously causes a structure-borne noise.

Bei den bekannten mit einer elektrischen Isolierung versehenen Rillenschienen bestehen die an dem Schienensteg anliegenden Teile der elektrischen Isolierung aus Vollkörpern, während lediglich die unterhalb des Schienenkopfes etwa senkrecht verlaufenden Bereiche der elektrischen Isolierung mit Hohlräumen versehen sind ( DE 299 23 532 Ul ). Durch diese Ausbildung der elektrischen Isolierung ist zwar eine vertikale Bewegung der Rillenschiene möglich, nicht aber eine horizontale Bewegung. Somit ist in horizontaler Richtung auch keine Körperschalldämpfung möglich.In the known grooved rails provided with an electrical insulation, the parts of the electrical insulation applied to the rail web consist of solid bodies, while only the areas of the electrical insulation extending approximately vertically below the rail head are provided with cavities ( DE 299 23 532 Ul ). Although this embodiment of the electrical insulation, a vertical movement of the grooved rail is possible, but not a horizontal movement. Thus, no structure-borne sound attenuation is possible in the horizontal direction.

WO-A-01/83889 zeigt eine Rillenschiene mit elektrischen Isolierung gemäß dem Oberbegriff des Anspruchs 1. WO-A-01/83889 shows a grooved rail with electrical insulation according to the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, eine mit einer elektrischen Isolierung versehene, elastisch gelagerte Rillenschiene der eingangs genannten Art derart auszubilden, dass sie bei guter elektrischer Isolierung sowohl horizontale als auch vertikale Bewegungen ausführen kann, also sowohl in horizontaler als auch in vertikaler Richtung eine Körperschalldämpfung bewirkt.The invention is based on the object, provided with an electrical insulation, elastically mounted Grooved rail of the type mentioned in such a way that they can perform both horizontal and vertical movements with good electrical insulation, thus causing both in the horizontal and in the vertical direction a structure-borne noise.

Die an die Rillenschiene anliegende elektrische Isolierung ist aus einer Außenschale und einer Innenschale gebildet , die durch Stege auf Abstand voneinander gehalten werden. Wegen des Abstandes der Außenschale und der Innenschale voneinander entstehen Hohlräume zwischen den beiden Schalen, die eine freie Beweglichkeit der Rillenschiene sowohl in horizontaler als auch in vertikaler Richtung ermöglichen, ohne dass an der Außenfläche der elektrischen Isolierung Reibung oder Verformungen entstehen können. Die erfindungsgemäße Isolierung der Rillenschiene bewirkt eine sehr hohe Vibrationsdämfung. Als Werkstoff für die elektrische Isolierung kommen verschiedene Kunststoffe in Betracht, beispielsweise thermoplastischer Kunststoff.The applied to the grooved rail electrical insulation is formed of an outer shell and an inner shell, which are held by webs at a distance from each other. Because of the distance between the outer shell and the inner shell of each other arise cavities between the two shells, which allow free movement of the grooved rail in both the horizontal and vertical direction without the outer surface of the electrical insulation friction or deformation can arise. The isolation of the grooved rail according to the invention causes a very high vibration damping. As a material for electrical insulation, various plastics come into consideration, such as thermoplastic.

Die Lösung der gestellten Aufgabe besteht darin, dass die die Außenschale und die Innenschale verbindenden Stege derart schräg angeordnet sind, dass sie im eingebauten Zustand der Rillenschiene, von der Außenschale zur Innenschale hin nach unten verlaufen, wobei deren obere Fläche mit der inneren Fläche der betreffenden Aussenschale (2) einen Winkel bildet, der größer als 90° ist. Durch diese Gestaltung der Stege werden sie bei vertikaler Absenkung der Rillenschiene nur geringfügig verformt.The solution of the problem is that the connecting the outer shell and the inner shell webs are arranged obliquely so that they run in the installed state of the grooved rail, from the outer shell to the inner shell down, the upper surface with the inner surface of the relevant Outer shell (2) forms an angle which is greater than 90 °. This design of the webs they are only slightly deformed at vertical lowering of the grooved rail.

Bei einer besonders einfachen Ausführungsform der erfindungsgemäßen Rillenschiene umfasst die elektrische Isolierung auch den Fuß der Rillenschiene. Die elektrische Isolierung besteht somit nur aus einem einzigen Teil und ist daher sehr leicht und kostengünstig herzustellen.In a particularly simple embodiment of the grooved rail according to the invention, the electrical insulation also includes the foot of the grooved rail. The electrical insulation thus consists of only one Part and is therefore very easy and inexpensive to manufacture.

In Ausgestaltung der Erfindung ist zwischen dem Fuß der Rillenschiene und dem unter dem Fuß der Rillenschiene befindlichen Bereich der elektrischen Isolierung ein elastisches Formteil angeordnet. Dieses Formteil bewirkt die elastische Lagerung der Rillenschiene. Das Formteil sollte eine möglichst geringe dynamische Steifigkeit aufweisen und besteht zweckmäßigerweise aus gummielastischem Werkstoff, also beispielsweise aus Gummi oder aus einem gummielastischen Kunststoff. Das Formteil ermöglicht verschiedene Einfederungen, beispielsweise 0,5 mm, 1 mm oder 1,5 mm.In an embodiment of the invention, an elastic molded part is arranged between the foot of the grooved rail and located under the foot of the grooved rail area of the electrical insulation. This molding causes the elastic mounting of the grooved rail. The molding should have the lowest possible dynamic stiffness and is expediently made of rubber-elastic material, so for example made of rubber or of a rubber-elastic plastic. The molded part allows various deflections, for example 0.5 mm, 1 mm or 1.5 mm.

In weiterer Ausgestaltung der Erfindung ist der unter dem Fuß der Rillenschiene befindliche Bereich der elektrischen Isolierung härter ausgebildet als die übrigen Bereiche der elektrischen Isolierung. Damit ist gewährleistet, dass der unter dem Fuß der Rillenschiene befindliche Bereich der elektrischen Isolierung stets vollflächig auf dem Untergrund der Rillenschiene (Beton o. dgl.) aufliegt.In a further embodiment of the invention located under the foot of the grooved rail area of the electrical insulation is harder than the other areas of electrical insulation. This ensures that the region of the electrical insulation located under the foot of the grooved rail always rests on the entire surface of the grooved rail (concrete or the like) over its full area.
