Definitions
- the elastic intermediate plate 3 which sits directly on the hard support 6 (concrete sleeper), has openings for the screws 7 of the multi-part rail fastening.
- the elastic intermediate plate 3 can be used without using the elastic intermediate layer 1 , even if the series connection is preferred.
- the elastic intermediate plate 3 has three zones A and B , the central zone B having a different structure with respect to the system of knobs and depressions than the two structurally identical side zones A, but with an essentially mirror-symmetrical overall structure, namely in relation to the central planes X and Y running in the transverse direction of the rail and in the longitudinal direction of the rail.
- the circumferential edge 9 is equipped with a total of four drainage channels 18 running in the transverse direction of the rails, which ensure that any water that has penetrated can drain off.
- the edge 9 also includes a system of knobs and depressions. There are four knobs 10 within the central region of the central zone B , which are arranged separately from one another. In addition, the central zone B also has two web-shaped knobs 11 which are arranged in the region of the central plane Y running in the longitudinal direction of the rail and are each connected to the peripheral edge 9 .
- the two side zones A each have a large base knob 12 which is arranged in the region of the central plane X running in the transverse direction of the rail and is connected to the circumferential edge 9 , each base knob being provided with an opening 16 for the screws of the rail fastening. Furthermore, each base knob is provided with two drainage channels 17 running in the longitudinal direction of the rail, specifically to form a two-part base knob 12a and 12b. A further knob 13 is arranged between the base knob and the peripheral edge, which knob is not connected to the edge and has its largest dimension in the transverse direction of the rail.
- Fig. 3 now shows a modified elastic intermediate plate 3 ' . Thereafter, the active areas of the four central knobs 10 ' as well as the two web-shaped knobs 11' within the central zone B are made substantially smaller than in the context of the exemplary embodiment according to FIG. 2. At the same time, the non-active area of the depression 14 ' has increased significantly.
- the base cone 12 ' provided with an opening 16' is provided here with a total of five drainage channels 17 ' , namely to form a five-part base cone 12' a, 12'b and 12'c.

Abstract
Description
Die Erfindung betrifft eine Schienenanordnung für eine Gleisoberbaukonstruktion wie feste Fahrbahn, umfassend eine elastische Zwischenplatte, die sich zwischen dem Schienenfuß und einem harten Auflager (z.B. Betontragplatten, Stahlschwellen, Betonschwellen) befindet und zumeist mit zwei Durchbrechungen für die Schrauben der Schienenbefestigung versehen ist, wobei die elastische Zwischenplatte
- aus einem einstückigen Vulkanisat besteht, hergestellt aus einer Kautschukmischung, insbesondere auf der Basis von Naturkautschuk (NR), epoxidiertem Naturkautschuk (ENR), Isoprenkautschuk (IR), Butadienkautschuk (BR), Acrylat-Kautschuk (ACM), Styrol-Butadien-Kautschuk (SBR) oder Verschnitten dieser Kautschuktypen, insbesondere NR/SBR- oder NR/BR-Verschnitte, sowie üblichen Mischungsingredienzien, wie Füllstoffe, Weichmacher, Alterungsschutzmittel sowie gegebenenfalls weitere Zusatzstoffe;
- eine im wesentlichen ebenflächige Oberseite besitzt, während ihre Unterseite einen umlaufenden Rand aufweist, der zumeist mit wenigstens einem in Schienenquerrichtung verlaufenden Dränkanal versehen ist, wobei der Rand ein System aus Noppen und Vertiefungen mit vorzugsweise im wesentlichen spiegelsymmetrischer Gesamtstruktur, und zwar bezogen auf die in Schienenquerrichtung und in Schienenlängsrichtung verlaufenden Mittelebenen, einschließt, wobei die Unterseite zumeist direkt auf dem harten Auflager aufsitzt; sowie
- drei Zonen aufweist, die sich im wesentlichen parallel zur Schienenlängsrichtung erstrecken, wobei die Mittelzone in Bezug auf das System aus Noppen und Vertiefungen eine andere Struktur besitzt als die beiden strukturgleichen Seitenzonen, und zwar derart, daß die Mittelzone eine größere gummielastische Verformbarkeit aufweist als die beiden Seitenzonen.
- consists of a one-piece vulcanizate, made from a rubber mixture, in particular based on natural rubber (NR), epoxidized natural rubber (ENR), isoprene rubber (IR), butadiene rubber (BR), acrylate rubber (ACM), styrene-butadiene rubber ( SBR) or blends of these types of rubber, in particular NR / SBR or NR / BR blends, as well as customary mixture ingredients, such as fillers, plasticizers, anti-aging agents and optionally other additives;
- has an essentially flat top, while its underside has a circumferential edge which is usually provided with at least one drainage channel running in the transverse direction of the rail, the edge being a system of knobs and depressions with an overall structure which is preferably essentially mirror-symmetrical, in relation to that in the transverse direction of the rail and in the longitudinal direction of the central planes, with the underside mostly sitting directly on the hard support; such as
- has three zones which extend essentially parallel to the longitudinal direction of the rail, the central zone having a different structure with respect to the system of knobs and depressions than the two structurally identical side zones, in such a way that the central zone has a greater rubber-elastic deformability than the two side zones.
Eine ähnliche Schienenanordnung ist aus der EP-A-0 541 884 bekann. Dabei wird beispielsweise vorgeschlagen, die elastische Zwischenplatte mit Sacklöchern oder zickzackförmigen Nuten zu versehen, wobei diese die Vertiefungen bildenden Elemente innerhalb der Mittelzone häufiger auftreten als innerhalb der beiden Seitenzonen, was dazu führt, daß die Mittelzone eine größere gummielastische Verformbarkeit aufweist als die beiden Seitenzonen. Ferner ist aus der DE-A-195 04 937 eine elastische zwischenlage bekannt, die mit einem Noppensystem versehen ist. Ein beträchtlicher Anteil des Personenfernverkehrs auf der Schiene wird bereits heute in mehreren Ländern, insbesondere in Frankreich, Japan und Deutschland, auf sogenannten Hochgeschwindigkeitsstrecken realisiert. Durch den Neubau derartiger Strecken, und zwar im Rahmen der Kopplung nationaler Hochgeschwindigkeitsstrecken in Europa zu einem internationalen Verbund unter gleichzeitiger Einbeziehung des Güterfernverkehrs (gemischte Nutzung der Strecken), schreitet diese Entwicklung weiter voran.A similar rail arrangement is known from EP-A-0 541 884. there For example, it is proposed that the elastic intermediate plate with blind holes or to provide zigzag grooves, these forming the recesses Elements within the central zone occur more frequently than within the two Side zones, which results in the central zone becoming a larger rubber elastic Has deformability than the two side zones. Furthermore, from DE-A-195 04 937 an elastic liner known with a knob system is provided. A significant proportion of long-distance passenger transport by rail is already today in several countries, especially in France, Japan and Germany so-called high-speed lines realized. By building new ones Routes, as part of the coupling of national high-speed lines in Europe to an international network with simultaneous involvement of long-distance freight transport (mixed use of routes), this development is progressing further ahead.
Nur in der Ausführungsart dieser Hochgeschwindigkeitsstrecken als sogenannte "Feste Fahrbahnen" auf Erdbauten, in Tunneln und auf Brücken wird - im Gegensatz zum klassischen Schotteroberbau - der Instandhaltungsaufwand vertretbar und somit eine instandhaltungsarme Langzeitnutzung möglich.Only in the design of these high-speed lines as so-called "festivals Roads "on earth structures, in tunnels and on bridges - in contrast to the classic ballast track - the maintenance effort is justifiable and therefore one Long-term, low-maintenance use possible.
Um nun optimalen Fahrkomfort, geringe Schwingungs- und Lärmbelästigung für die Streckenanlieger, geringe dynamische Fahrwegbeanspruchung und hohe Verfügbarkeit der Fahrwege zu erreichen, werden an die elastische Zwischenplatte folgende Anforderungen gestellt, nämlich:
- Statische Sekantensteifigkeit Cstat= 10 bis 30 kN/mm,
insbesondere 15 bis 25 kN/mm
(Untergrenze 15 kN,Obergrenze 50 kN) - Dynamischer Versteifungsfaktor æ ≤ 2,5 insbesondere ≤ 1,5
- Static secant stiffness C stat = 10 to 30 kN / mm,
in particular 15 to 25 kN / mm
(Lower limit 15 kN,upper limit 50 kN) - Dynamic stiffening factor æ ≤ 2.5, in particular ≤ 1.5
Diese Anforderungen unter Beachtung der Ermüdungsbeständigkeit und Dauerfestigkeit (Lebensdauer) kann mit einer einstückigen Zwischenplatte, hergestellt als Formartikel, auf TPE-Werkstoffbasis nicht erfüllt werden. Ohne deutliche Vergrößerung der Bauhöhe sind die oben aufgeführten Vorgaben für Cstat mit einem verträglichen dynamischen Versteifungsfaktor über die geforderte Lebensdauer mit einem TPE-Werkstoff nicht erreichbar. Diese Anforderungen sind nur erfüllbar in Verbindung mit Vulkanisaten, hergestellt aus einer Kautschukmischung, insbesondere unter Anwendung der Kautschuktypen NR, ENR, IR, BR, ACM, SBR, NR/SBR oder NR/BR, und zwar unter Einbezug einer geeigneten Konstruktion der elastischen Zwischenplatte.These requirements, taking into account fatigue resistance and fatigue strength (service life), cannot be met with a one-piece intermediate plate, manufactured as a molded article, based on TPE material. Without a significant increase in the overall height, the above-mentioned specifications for C stat with a compatible dynamic stiffening factor cannot be achieved with the TPE material over the required service life. These requirements can only be met in connection with vulcanizates made from a rubber mixture, in particular using the rubber types NR, ENR, IR, BR, ACM, SBR, NR / SBR or NR / BR, with the inclusion of a suitable construction of the elastic intermediate plate ,
Die erfindungsgemäße elastische Zwischenplatte zeichnet sich nun durch folgenden konstruktiven Aufbau aus:
- Die Vertiefungen innerhalb der drei Zonen sind als nichtaktive Flächen gestaltet, die zugleich den Boden bilden, der die geschlossene Begrenzung zur Oberseite der elastischen Zwischenplatte darstellt, wobei die nichtaktiven Flächen innerhalb der Mittelzone tiefer liegen als die der beiden Seitenzonen sowie ferner innerhalb einer Zone eine im wesentlichen gleichbleibende Tiefe aufweisen.
- Die aktiven Flächen der Noppen innerhalb der Mittelzone weisen eine kleinere Gesamtfläche auf als die der Noppen innerhalb jeder Seitenzone.
- Die beiden Seitenzonen nehmen jeweils eine größere Fläche als die Mittelzone ein.
- The depressions within the three zones are designed as non-active areas, which also form the floor, which forms the closed boundary to the upper side of the elastic intermediate plate, the non-active areas within the central zone being lower than that of the two side zones and also within one zone have a substantially constant depth.
- The active areas of the knobs within the central zone have a smaller total area than that of the knobs within each side zone.
- The two side zones each take up a larger area than the central zone.

Fig. 1 zeigt eine Schienenanordnung, bei der im Rahmen einer Reihenschaltung die elastische Zwischenplatte 3 mit einer elastischen Zwischenlage 1 kombiniert ist, und zwar derart, daß die zusätzliche Zwischenlage oberhalb der Zwischenplatte direkt unterhalb des Schienenfußes zu liegen kommt, wobei die Zwischenlage 1 von der Zwischenplatte 3 durch eine Grundplatte 2 aus Metall, die der Schienenbefestigung dient, getrennt ist. Die elastische Zwischenlage 1 hat etwa die Breite des Schienenfußes. Die elastische Zwischenplatte 3 besitzt im Vergleich zur Zwischenlage 1 etwa den doppelten Flächenbedarf, wobei hinsichtlich der Gesamtstärke dieser beiden Elastomersysteme folgende Werte gelten:
- elastische Zwischenlage 1:
mindestens 7 mm - elastische Zwischenplatte 3:
mindestens 10 mm
- elastic intermediate layer 1: at least 7 mm
- elastic intermediate plate 3: at least 10 mm
Die elastische Zwischenplatte 3, die direkt auf dem harten Auflager 6 (Betonschwelle)
aufsitzt, weist Durchbrechungen auf für die Schrauben 7 der mehrteiligen
Schienenbefestigung.The elastic
Im Rahmen einer alternativen Gestaltungsvariante kann die elastische Zwischenplatte
3 ohne Verwendung der elastischen Zwischenlage 1 eingesetzt werden, auch wenn die
Reihenschaltung bevorzugt wird.In the context of an alternative design variant, the elastic
Bei der Reihenschaltung ist es ferner von Vorteil, wenn die resultierende Federsteife stets kleiner ist als die kleinste Einzelfedersteife.With the series connection, it is also advantageous if the resulting spring stiffness is always smaller than the smallest single spring stiffness.
Bevor nun näher auf die erfindungsgemäße elastische Zwischenplatte 3 eingegangen wird, bleiben noch die vorteilhaften Ausgestaltungsvarianten der elastischen Zwischenlage 1 zu erwähnen. Diese sind:
Die Zwischenlage 1 besteht aus einem einstückigen Vulkanisat, insbesondere auf der Basis des gleichen Werkstoffes wie bei derZwischenplatte 3. Der Kautschukanteil beträgt dabei 45 bis 75 Gew.-%, insbesondere 55 bis 65 Gew.-%.Die Zwischenlage 1 besitzt eine im wesentlichen ebenflächige Oberseite, während ihre Unterseite einen umlaufenden Rand aufweist, der zumeist mit wenigstens einem in Schienenquerrichtung verlaufenden Dränkanal versehen ist, wobei der Rand ein System aus Noppen und Vertiefungen mit vorzugsweise im wesentlichen spiegelsymmetrischer Gesamtsturktur, und zwar bezogen auf die in Schienenquerrichtung und in Schienenlängsrichtung verlaufenden Mittelebenen, einschließt. Die Vertiefungen, die die nichtaktiven Flächen bilden, weisen überall im wesentlichen die gleiche Tiefe auf, und zwar bei einerMindesttiefe von 3 mm. Die aktiven Flächen der Noppen und die Oberfläche des umlaufenden Randes sind ferner so gestaltet, daß diese im unbelasteten Zustand eine im wesentlichen ebene Auflagefläche bilden.Bei der Zwischenlage 1 ist die Gesamtfläche aller Noppen ≥ der Gesamtfläche der nichtaktiven Flächen aller Vertiefungen.
- The
intermediate layer 1 consists of a one-piece vulcanizate, in particular based on the same material as in theintermediate plate 3. The rubber content is 45 to 75% by weight, in particular 55 to 65% by weight. - The
intermediate layer 1 has a substantially flat top, while its underside has a circumferential edge which is usually provided with at least one drainage channel running in the transverse direction of the rail, the edge being a system of knobs and depressions, preferably with an essentially mirror-symmetrical overall structure, with reference to the central planes running in the transverse direction of the rail and in the longitudinal direction of the rail. The depressions which form the non-active areas have essentially the same depth everywhere, with a minimum depth of 3 mm. The active surfaces of the knobs and the surface of the peripheral edge are also designed so that they form a substantially flat contact surface in the unloaded state. - In the case of the
intermediate layer 1 , the total area of all knobs is ≥ the total area of the non-active areas of all depressions.
Nach Fig. 2 weist die elastische Zwischenplatte 3 drei Zonen A und B auf, wobei die
Mittelzone B in Bezug auf das System aus Noppen und Vertiefungen eine andere
Struktur besitzt als die beiden strukturgleichen Seitenzonen A, jedoch bei einer im
wesentlichen spiegelsymmetrischen Gesamtstruktur, und zwar bezogen auf die in
Schienenquerrichtung und in Schienenlängsrichtung verlaufenden Mittelebenen X
und Y.According to FIG. 2, the elastic
Der umlaufende Rand 9 ist insgesamt mit vier in Schienenquerrichtung verlaufenden
Dränkanälen 18 ausgestattet, die dafür sorgen, daß eventuell eingedrungenes Wasser
abfließen kann.The
Der Rand 9 schließt ferner ein System aus Noppen und Vertiefungen ein. Dabei sind
innerhalb des mittigen Bereiches der Mittelzone B vier Noppen 10 vorhanden, die
getrennt zueinander angeordnet sind. Außerdem weist die Mittelzone B noch zwei
stegförmige Noppen 11 auf, die im Bereich der in Schienenlängsrichtung verlaufenden
Mittelebene Y angeordnet sind und dabei jeweils mit dem umlaufenden Rand 9
verbunden sind.The
Die beiden Seitenzonen A weisen jeweils eine große Basisnoppe 12 auf, die im
Bereich der in Schienenquerrichtung verlaufenden Mittelebene X angeordnet und mit
dem umlaufenden Rand 9 verbunden ist, wobei jede Basisnoppe mit einer
Durchbrechung 16 für die Schrauben der Schienenbefestigung versehen ist. Ferner ist
jede Basisnoppe mit zwei in Schienenlängsrichtung verlaufenden Dränkanälen 17
versehen, und zwar unter Bildung einer zweiteiligen Basisnoppe 12a und 12b.
Zwischen der Basisnoppe und dem umlaufenden Rand ist eine weitere Noppe 13
angeordnet, die nicht mit dem Rand verbunden ist und in Schienenquerrichtung ihre
größte Erstreckungsdimension besitzt.The two side zones A each have a
Fig. 3 zeigt nun eine modifizierte elastische Zwischenplatte 3'. Danach sind die aktiven Flächen der vier zentralen Noppen 10' wie auch die beiden stegförmigen Noppen 11' innerhalb der Mittelzone B wesentlich kleiner ausgebildet als im Rahmen des Ausführungsbeispieles gemäß Fig. 2. Gleichzeitig hat sich hier die nichtaktive Fläche der Vertiefung 14' deutlich vergrößert.Fig. 3 now shows a modified elastic intermediate plate 3 ' . Thereafter, the active areas of the four central knobs 10 ' as well as the two web-shaped knobs 11' within the central zone B are made substantially smaller than in the context of the exemplary embodiment according to FIG. 2. At the same time, the non-active area of the depression 14 ' has increased significantly.
Was die Noppenkonstellation innerhalb der beiden strukturgleichen Seitenzonen A betrifft, so zeichnet sich diese zum einen dadurch aus, daß die mit einer Durchbrechung 16' versehene Basisnoppe 12' hier mit insgesamt fünf Dränkanälen 17' versehen ist, und zwar unter Bildung einer fünfteiligen Basisnoppe 12'a, 12'b und 12'c. Zum anderen sind zwischen der Basisnoppe und dem umlaufenden Rand 9' zwei Noppen 13' vorhanden, die getrennt zueinander angeordnet sind. Gegebenenfalls ist eine dritte Noppe 13' (gestrichelte Linienführung) vorhanden. Die Noppen 13' innerhalb der Seitenzone A weisen jeweils eine etwa gleich große aktive Fläche auf, die wiederum etwa gleich groß ist wie die aktive Fläche jeder Noppe 10' der Mittelzone B. With regard to the cone constellation within the two structurally identical side zones A , this is distinguished on the one hand by the fact that the base cone 12 ' provided with an opening 16' is provided here with a total of five drainage channels 17 ' , namely to form a five-part base cone 12' a, 12'b and 12'c. On the other hand, between the base knob and the peripheral edge 9 'there are two knobs 13' which are arranged separately from one another. A third knob 13 ' (dashed lines) may be present. The knobs 13 ' within the side zone A each have an approximately equal active area, which in turn is approximately the same size as the active area of each knob 10' in the central zone B.
