Gegenstand des Gebrauchsmusters ist eine hochelastische Schienenunterlage mit ausgeprägter Schwingungsdämpfung durch Verwendung von Kunststoffen mit unterschiedlicher Elastizität in verschiedenen Belastungsbereichen.The subject of the utility model is a highly elastic rail base with pronounced vibration damping through the use of plastics with different elasticities in different load ranges.

Es sind hochelastische Schienenunterlagen als Zwischenlagen mit guter Kraftverteilung in Schienenlängsrichtung und mit Körperschall reduzierender Wirkung bekannt, die aus verschiedenen Kunststoffarten bestehen.Highly elastic rail supports are known as intermediate layers with good force distribution in the longitudinal direction of the rail and with a structure-borne sound-reducing effect, which consist of various types of plastic.

Die Nachteile dieser Ausführungen aus herkömmlichen Kunststoffen in relativ weicher Einstellung liegen vor allem darin, daß von der Schiene dadurch verstärkte Luftschallabstrahlungen ausgehen und die auftretenden Horizontalkräfte verhältnismäßig große Kippbewegungen der Schiene verursachen. Zur Begrenzung der Kippbewegungen der Schiene werden aufwendige konstruktive Maßnahmen, z.B. durch den Einsatz von versteifenden Stahlpiatten und / oder Vergrößerung der Schienenunterlage angewandt.The disadvantages of these designs made of conventional plastics in a relatively soft setting are primarily that the rail emits increased airborne noise and the horizontal forces that occur cause relatively large tilting movements of the rail. To limit the tilting movements of the rail, complex structural measures are used, e.g. by using stiffening steel plates and/or enlarging the rail base.

Zur Vermeidung dieser Nachteile besteht nach dem Gebrauchsmuster die hochelastische Schienenunterlage aus Kunststoff mit mindestens zwei unterschiedlich elastischen Bereichen, wobei diese eine relativ harte Umrandung und weicheren Innenbereich aufweist, die zweiteilig getrennt oder einstückig einseitig profiliert ist.To avoid these disadvantages, according to the utility model, the highly elastic rail base is made of plastic with at least two differently elastic areas, whereby this has a relatively hard border and a softer inner area which is separated in two parts or is profiled in one piece on one side.

Durch Kombination in Elastizität, Umfang und Größe der Bereiche wird die geforderte Eigenschaft erreicht. Ausführungsbeispiele zeigen die Abbildungen 1 und 2. In Fig. 1 besteht die hochelastische Schienenunterlage aus Kunststoff mit einer hart eingestellten Umrandung (1 ) und einem Mitteibereich (2 ), der weicher und dicker ausgebildet ist. Teil 1 besteht aus PU-Elastomer und Teil 2 aus zelligem PU-EIastomer. The required properties are achieved by combining the elasticity, extent and size of the areas. Examples of implementation are shown in Figures 1 and 2. In Figure 1, the highly elastic rail base is made of plastic with a hard border (1) and a middle area (2) that is softer and thicker. Part 1 is made of PU elastomer and part 2 is made of cellular PU elastomer.

In Fig. 2 wird die unterschiedliche Elastizität der Schienenunterlage durch Noppen ( 3 ) auf der Schwellenseite der Schienenunterlage
erreicht. Die schienenseitig angeordneten Noppen ( 3 ) sind in Dicke, Form und Verteilung auf den gewünschten Effekt ausgerichtet, z.B. in runder und / oder eckiger Form und in verschiedener Dicke und höher als die Umrandung (1 ) der Schienenunteriage, wobei die Länge auf die Schienenlängsrichtung bezogen größer als die Breite ist.
In Fig. 2, the different elasticity of the rail base is represented by studs ( 3 ) on the sleeper side of the rail base
achieved. The studs (3) arranged on the rail side are aligned in thickness, shape and distribution to the desired effect, e.g. in round and/or square shape and in different thicknesses and higher than the edge (1) of the rail base, whereby the length in the longitudinal direction of the rail is greater than the width.

Für das Wirkungsprinzip der hochelastischen Schienenunterlage ist es unerheblich, ob diese in Schienenlängsrichtung einseitig oder mittig geteilt ist. Die geteilte Ausführung erlaubt den Einsatz für verschiedene Schienenfußbreiten.For the functioning principle of the highly elastic rail base, it is irrelevant whether it is split on one side or in the middle in the longitudinal direction of the rail. The split design allows it to be used for different rail base widths.

Die Vorteile der vorgeschlagenen hochelastischen Schienenunterlage liegen vor allem in einer hohen Anfangselastizität, einer sodann unter Belastung verringerten Elastizität im oberen Belastungsbereich, wie diese z.B. in Kurven auftritt bei gleichzeitig verbesserter Lastverteilung auf Nachbarschwellen. Des weiteren wird eine Vergrößerung der Wellenlänge der Schienenbiegelinie erreicht und eine Verbesserung des Schwingungsverhaltens im Teilsystem Schiene gegenüber den unabgefederten Massen der Schienenfahrzeuge. Die kombinierten unterschiedlichen Eigenschaften der Schienenunterlage vermindern den Körper- und Luftschali wie Messungen gezeigt haben. Die Ausführungsform nach Fig. 1 läßt gem. Fig. 3 erkennen, daß diese Wirkung auch praktisch eintritt. Im Kraft-(x) -Wege-(y)-digramm ist Federkennlinie 1 von einer herkömmlichen Ausführung einer Schienenunterlage und das Diagramm 2 entsprechend Fig. 1 dargestellt.The advantages of the proposed highly elastic rail base lie primarily in a high initial elasticity, then a reduced elasticity under load in the upper load range, as occurs, for example, in curves, with simultaneously improved load distribution on neighboring sleepers. Furthermore, an increase in the wavelength of the rail bending line is achieved and an improvement in the vibration behavior in the rail subsystem compared to the unsprung masses of the rail vehicles. The combined different properties of the rail base reduce body and air noise, as measurements have shown. The embodiment according to Fig. 1 shows, according to Fig. 3, that this effect also occurs in practice. In the force (x) - path (y) diagram, spring characteristic curve 1 of a conventional design of a rail base and diagram 2 corresponding to Fig. 1 are shown.
