Description

Die Erfindung betrifft eine Anordnung zur Lagerung einer Schienenfahrbahn, mit einer zwischen einer Schiene und einer Schwelle positionierbaren elastischen Zwischenlage und einer Noppen aufweisenden Unterlage, wobei die elastische Zwischenlage wenigstens eine Reihe von Durchgangslöchern aufweist, in die im montierten Zustand die Noppen der Unterlage eingreifen.The invention relates to an arrangement for supporting a rail track, with a positionable between a rail and a threshold elastic intermediate layer and a nubbed pad, wherein the elastic intermediate layer has at least one row of through holes into which engage in the mounted state, the nubs of the pad.

Aus der GB 2 094 377 A ist eine Anordnung zur Lagerung einer Schienenfahrbahn bekannt, mit einer zwischen einer Schiene und einer Schwelle positionierbaren elastischen Zwischenlage sowie einer Unterlage, wobei die elastische Zwischenlage Durchgangslöcher aufweist, in die im montierten Zustand an der Unterlage angeordnete Noppen eingreifen. Die Höhe der Noppen ist nicht größer als die Dicke der elastischen Zwischenlage.From the GB 2 094 377 A an assembly for supporting a rail track is known, with a positionable between a rail and a threshold elastic intermediate layer and a base, wherein the elastic intermediate layer has through holes, engage in the mounted state in the pad arranged nubs. The height of the nubs is not greater than the thickness of the elastic intermediate layer.

Die Druckschriften GB 2 235 003 A und US 2007/210178 A1 offenbaren ebenfalls elastische Zwischenlagen, die zur Lagerung einer Schwelle einer Schienenfahrbahn dienen.The pamphlets GB 2 235 003 A and US 2007/210178 A1 also disclose elastic intermediate layers which serve to support a threshold of a railroad track.

Zur Lagerung einer Schienenfahrbahn werden üblicherweise Zwischenlagen benutzt, um dem Gleis eine bestimmte Elastizität zu verleihen. Bei bestimmten Anwendungen, beispielsweise bei Schienenfahrbahnen für Straßenbahnen, treten neben vertikalen Kräften in Kurven auch erhöhte horizontale Kräfte auf. Die von dem Schienenfahrzeug auf die Schiene übertragene resultierende Kraft ist dabei zur Kurvenaußenseite gerichtet. Die horizontale Komponente dieser schräg angreifenden Kraft verursacht somit ein auf die Schiene einwirkendes Kippmoment. Durch steife Schienenbefestigungen könnte ein dadurch verursachtes Kippen der Schiene ohne Weiteres verhindert werden, allerdings wird häufig ein "elastisches" Gleis gewünscht, um eine definierte Schieneneinsenkung zu erreichen sowie die Übertragung von Vibrationen und Schall auf den Untergrund zu verringern. Nachteilig ist dabei allerdings, dass ein derartiges elastisches Gleis, bei dem weiche Schienenbefestigungen und eine weiche Zwischenlage verwendet werden, bei einer bestimmten Belastung zum Kippen der Schiene neigen kann. Um derartige Kippbewegungen zu verhindern, werden üblicherweise Winkelführungsplatten eingesetzt, die eine Kante aufweisen, die ein Kippen der Schiene verhindert. Derartige Winkelführungsplatten erhöhen jedoch die Herstellungskosten einer Schienenfahrbahn und erschweren die Instandhaltung.For storage of a railroad track liners are usually used to give the track a certain elasticity. In certain applications, such as trams for trams, in addition to vertical forces in curves also increased horizontal forces occur. The transmitted from the rail vehicle to the rail resulting force is directed to the outside of the curve. The horizontal component of this obliquely acting force thus causes a tilting moment acting on the rail. Rigid rail fastenings could easily prevent tilting of the rail caused thereby, but often an "elastic" track is desired to achieve a defined rail depression and reduce the transmission of vibration and sound to the ground. The disadvantage here, however, is that such an elastic track, in which soft rail fasteners and a soft intermediate layer are used, may tend to tilt the rail at a certain load. To prevent such tilting, usually angle guide plates are used which have an edge which prevents tilting of the rail. However, such angled guide plates increase the cost of a rail track and make maintenance difficult.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Anordnung zur Lagerung einer Schienenfahrbahn anzugeben, bei der ein Kippen der Schiene verhindert wird und die kostengünstig herstellbar ist.The invention is therefore based on the object to provide an arrangement for supporting a rail track, in which a tilting of the rail is prevented and which is inexpensive to produce.

Zur Lösung dieser Aufgabe ist bei einer Anordnung zur Lagerung der Schienenfahrbahn der eingangs genannten Art erfindungsgemäß vorgesehen, dass die elastische Zwischenlage 1,5 mm bis 3 mm dicker als die Höhe der Noppen ist.To solve this problem, it is provided according to the invention in an arrangement for supporting the rail track of the type mentioned that the elastic intermediate layer is 1.5 mm to 3 mm thicker than the height of the knobs.

Die Erfindung beruht auf der Erkenntnis, dass mittels der Noppen einerseits ein zu starkes einseitiges Einsenken der Schiene vermieden werden kann, andererseits wird eine gewisse vertikale Schieneneinsenkung zugelassen. Bei der erfindungsgemäßen Anordnung ist eine Relativbewegung zwischen der elastischen Zwischenlage, die die Durchgangslöcher aufweist, und den an der Unterlage angeordneten Noppen möglich. Zwischen den Noppen und der Zwischenlage im Bereich der Durchgangslöcher ist ein Formschluss gebildet, der eine gewisse, geringe Verformung der elastischen Zwischenlage zulässt, eine größere Verformung wird jedoch durch die in die Durchgangslöcher eingreifenden Noppen verhindert. Gleichzeitig ermöglicht die Zwischenlage, die aus einem im Vergleich zur Unterlage wesentlich elastischeren Werkstoff hergestellt ist, die gewünschte Vertikalbewegung der Schiene, wodurch die Übertragung von Schall und Vibrationen reduziert wird.The invention is based on the recognition that by means of the knobs, on the one hand, an excessively one-sided countersinking of the rail can be avoided, on the other hand, a certain vertical rail depression is permitted. In the arrangement according to the invention, a relative movement between the elastic intermediate layer, which has the through holes, and the nubs arranged on the base is possible. Between the knobs and the intermediate layer in the region of the through holes, a positive connection is formed, which allows a certain small deformation of the elastic intermediate layer, but a greater deformation is prevented by the nubs engaging in the through holes. At the same time, the intermediate layer, which is made of a material which is substantially more elastic than the base, allows the desired vertical movement of the rail, which reduces the transmission of sound and vibrations.

Gemäß einer ersten Ausgestaltung der erfindungsgemäßen Anordnung können die Noppen an der Oberseite einer die Unterlage bildenden Schwelle angeordnet sein. Der in dieser Anmeldung verwendete Begriff "Schwelle" umfasst nicht nur herkömmliche Betonschwellen mit Spannbewehrung oder schlaffer Bewehrung, sondern auch Fertigteilelemente, die zur Herstellung einer festen Fahrbahn vorgefertigt und anschließend auf einer Tragplatte ausgerichtet und mit Beton vergossen werden. Ebenso sind aufgelagerte Systeme von dem Begriff Schwelle umfasst, bei denen Fertigteilelemente auf eine tragende Schicht aufgelegt werden. Die Noppen können auch direkt an der Oberseite einer Schwelle angeordnet sein, die elastische Zwischenlage wird dann auf die Schwellen aufgelegt.According to a first embodiment of the arrangement according to the invention, the knobs can be arranged at the top of a threshold forming the base. The term "threshold" used in this application includes not only conventional concrete sleepers with tension reinforcement or limp reinforcement, but also precast elements that are prefabricated for the production of a solid roadway and then aligned on a support plate and cast with concrete. Likewise, superposed systems are encompassed by the term threshold, in which precast elements are placed on a supporting layer. The knobs can also be arranged directly on top of a threshold, the elastic intermediate layer is then placed on the thresholds.

Gemäß einer alternativen Ausgestaltung der erfindungsgemäßen Anordnung kann es vorgesehen sein, dass die Noppen an der Oberseite einer die Unterlage bildenden Noppenplatte angeordnet sind. Eine derartige Noppenplatte kann bei der Herstellung der Schienenfahrbahn auf der Oberseite einer Schwelle positioniert und befestigt werden. Diese Ausgestaltung weist den Vorteil auf, dass die Noppenplatten nur an den Stellen verlegt werden müssen, an denen sie auch benötigt werden, das heißt, primär in Kurvenbereichen. Da die Noppenplatten separat von den Schwellen ausgebildet sind, ist keine Modifikation von Schwellen erforderlich, wodurch sich Vorteile hinsichtlich der Typenvielfalt ergeben.According to an alternative embodiment of the arrangement according to the invention, it can be provided that the knobs are arranged on the top of a nub plate forming the base. Such a studded plate can be positioned and fastened in the production of the railroad track on the top of a threshold. This embodiment has the advantage that the studded plates only have to be laid at the points where they are needed, that is, primarily in curved areas. Since the studded plates are formed separately from the sleepers, no modification of sleepers is required, resulting in advantages in terms of variety of types.

Bei der erfindungsgemäßen Anordnung wird es bevorzugt, dass die Noppenplatte aus einem Kunststoffmaterial besteht, insbesondere aus Polyamid. Derartige Noppenplatten können einfach hergestellt werden, beispielsweise im Spritzgussverfahren. Um die mechanischen Kennwerte der Noppenplatte zu verbessern, kann es vorgesehen sein, dass sie aus einem glasfaserverstärkten Kunststoffmaterial hergestellt ist. Beispielsweise kann der Glasfaseranteil 10 % bis 40 % betragen, vorzugsweise ca. 30 %.In the arrangement according to the invention it is preferred that the studded plate consists of a plastic material, in particular of polyamide. Such knobbed plates can be easily manufactured, for example by injection molding. In order to improve the mechanical characteristics of the studded plate, it may be provided that it is made of a glass fiber reinforced plastic material. For example, the glass fiber content may be 10% to 40%, preferably about 30%.

Es liegt auch im Rahmen der Erfindung, dass die Zwischenlage der erfindungsgemäßen Anordnung zwei an gegenüberliegenden Seiten angeordnete parallele Reihen von beabstandeten Durchgangslöchern aufweist. Obwohl die Zwischenlage der erfindungsgemäßen Anordnung im einfachsten Fall lediglich eine Reihe von Durchgangslöchern aufweist, wird es bevorzugt, dass zwei Reihen von Durchgangslöchern vorhanden sind, die voneinander beabstandet und in gegenüberliegenden Randbereichen der Zwischenlage angeordnet sind. Vorzugsweise sind zwischen den beiden Reihen der Durchgangslöcher keine weiteren Durchgangslöcher vorhanden.It is also within the scope of the invention that the intermediate layer of the arrangement according to the invention comprises two parallel rows of spaced-through holes arranged on opposite sides. Although the intermediate layer of the arrangement according to the invention in the simplest case has only one row of through-holes, it is preferred that there are two rows of through-holes which are spaced from each other and in opposite edge regions of the intermediate layer are arranged. Preferably, there are no further through-holes between the two rows of through-holes.

Eine Variante der erfindungsgemäßen Anordnung sieht vor, dass die Durchgangslöcher zylindrisch ausgebildet sind. Auf diese Weise wird ein Verkanten der Zwischenlage und der Noppenplatte verhindert.A variant of the arrangement according to the invention provides that the through holes are cylindrical. In this way, tilting of the intermediate layer and the studded plate is prevented.

Vorzugsweise weist die Noppenplatte zwei an gegenüberliegenden Seiten angeordnete Reihen von Noppen auf. Dazwischen sind vorzugsweise keine Noppen ausgebildet.Preferably, the nubbed plate has two rows of nubs arranged on opposite sides. In between, preferably no nubs are formed.

Im Hinblick auf die Noppen, die an der Unterlage angeordnet sind, kann es vorgesehen sein, dass diese zylindrisch (rund) oder rechteckig oder konisch oder oval geformt sind. Vorzugsweise besitzen die Noppen einen konischen oder kegelstumpfförmigen Endabschnitt. Der Durchmesser der Noppen und der Durchmesser der Durchgangslöcher ist dabei so gewählt, dass die gewünschte Relativbewegung ermöglicht wird. Besonders bevorzugt wird dabei die Variante, dass die Noppen einen konischen oder kegelstumpfförmigen Endabschnitt aufweisen. Der Endabschnitt ist vorzugsweise an einen zylinderförmigen Abschnitt der Noppen angeformt. Vorzugsweise kann sich der konische oder kegelstumpfförmige Endabschnitt über 60% bis 90%, vorzugsweise über näherungsweise 75%, der Höhe der Noppen erstrecken.With regard to the nubs, which are arranged on the base, it may be provided that they are cylindrical (round) or rectangular or conical or oval shaped. Preferably, the nubs have a conical or frusto-conical end portion. The diameter of the knobs and the diameter of the through holes is chosen so that the desired relative movement is made possible. Particularly preferred is the variant that the knobs have a conical or frusto-conical end portion. The end portion is preferably formed on a cylindrical portion of the nubs. Preferably, the conical or frusto-conical end portion may extend over 60% to 90%, preferably over approximately 75%, of the height of the dimples.

Bei der erfindungsgemäßen Anordnung ist es vorgesehen, dass die Dicke der elastischen Zwischenlage größer als die Höhe der Noppen ist. Dadurch wird eine vertikale Verformung und somit eine Einsenkung der Schienen ermöglicht. Anderenfalls, wenn die elastische Zwischenlage und die Noppen dieselbe Höhe hätten, wären die Schienen direkt auf den nicht elastischen Noppen aufgelagert, so dass keine Einsenkung möglich wäre.In the arrangement according to the invention, it is provided that the thickness of the elastic intermediate layer is greater than the height of the knobs. This allows a vertical deformation and thus a depression of the rails. Otherwise, if the elastic intermediate layer and the dimples had the same height, the rails would be supported directly on the non-elastic dimples, so that no depression would be possible.

Bei der erfindungsgemäßen Anordnung ist die Zwischenlage 1,5 mm bis 3 mm höher bzw. dicker als die Höhe der Noppen.In the arrangement according to the invention, the intermediate layer is 1.5 mm to 3 mm higher or thicker than the height of the knobs.

Daneben betrifft die Erfindung eine Schienenfahrbahn, umfassend eine Schiene, die mittels Schienenbefestigungen auf einer Schwelle angeordnet ist, wobei zwischen der Schiene und der Schwelle eine elastische Zwischenlage der beschriebenen Art angeordnet ist, in deren Durchgangslöcher Noppen eingreifen, die entweder an einer auf der Schwelle angeordneten Noppenplatte oder an der Oberseite der Schwelle angeformt sind.In addition, the invention relates to a rail track, comprising a rail which is arranged by means of rail fastenings on a threshold, wherein between the rail and the threshold, an elastic intermediate layer of the type described is arranged, in whose through holes engage knobs, which are arranged either at one on the threshold Noppenplatte or at the top of the threshold are formed.

Die in Fig. 1 gezeigte Anordnung 1 dient zur Lagerung einer Schienenfahrbahn und umfasst eine elastische Zwischenlage 2 und eine Noppenplatte 3. Die elastische Zwischenlage 2 ist aus einem Elastomermaterial, beispielsweise einem Gummimaterial, hergestellt und weist eine plattenförmige, rechteckige Grundform auf, wie am besten in Fig. 2 zu sehen ist. Die elastische Zwischenlage 2 weist zwei an gegenüberliegenden Seiten angeordnete Reihen 4, 5 von zueinander beabstandeten Durchgangslöchern 6 auf. Die Durchgangslöcher 6 sind kreisförmig bzw. zylinderförmig ausgebildet.In the Fig. 1 Arrangement 1 serves to support a rail track and comprises an elastic intermediate layer 2 and a stud plate 3. The elastic intermediate layer 2 is made of an elastomer material, for example a rubber material, and has a plate-shaped, rectangular basic shape, as best in Fig. 2 you can see. The elastic intermediate layer 2 has two rows 4, 5 arranged on opposite sides of each other spaced through holes 6. The through holes 6 are circular or cylindrical.

Die Noppenplatte 3 ist aus einem Kunststoffmaterial hergestellt, in dem dargestellten Ausführungsbeispiel handelt es sich dabei um glasfaserverstärktes Polyamid. Im Vergleich zu der elastischen Zwischenlage 2 ist die Noppenplatte steif.The nubbed plate 3 is made of a plastic material, in the illustrated embodiment, it is glass fiber reinforced polyamide. Compared to the elastic intermediate layer 2, the studded plate is stiff.

Länge und Breite der Noppenplatte 3 stimmen mit den entsprechenden Maßen der elastischen Zwischenlage 2 überein. Die Noppenplatte 3 weist eine Mehrzahl von Noppen 7 auf, die sich senkrecht zu der von der Noppenplatte 3 gebildeten Ebene erstrecken. Die Position der Noppen 7 entspricht der Position der Durchgangslöcher 6 der elastischen Zwischenlage 2, das heißt jedem Durchgangsloch 6 ist eine Noppe 7 zugeordnet. Der Innendurchmesser der Durchgangslöcher 6 und der Außendurchmesser der Noppen 7 sind dabei so gewählt, dass die elastische Zwischenlage 2 auf die Noppenplatte 3 aufgelegt werden kann, so dass die Noppen 7 in die Durchgangslöcher 6 eingreifen. In der geschnittenen Ansicht von Fig. 3 erkennt man, wie die elastische Zwischenlage 2 und die Noppenplatte 3 nach der Montage ineinander eingreifen.Length and width of the studded plate 3 are consistent with the corresponding dimensions of the elastic intermediate layer 2. The nubbed plate 3 has a plurality of nubs 7, which extend perpendicular to the plane formed by the nubbed plate 3. The position of the nubs 7 corresponds to the position of the through holes 6 of the elastic intermediate layer 2, that is, each through hole 6 is associated with a nub 7. The inner diameter of the through holes 6 and the outer diameter of the knobs 7 are chosen so that the elastic intermediate layer 2 can be placed on the knob plate 3, so that the knobs 7 engage in the through holes 6. In the sectional view of Fig. 3 it can be seen how the elastic intermediate layer 2 and the studded plate 3 engage each other after assembly.

Fig. 4 ist eine vergrößerte Detailansicht der geschnittenen Ansicht von Fig. 3 im Bereich einer Noppe 7. Die Noppen 7 weisen einen zylindrischen Abschnitt 8 und einen sich daran anschließenden kegelstumpfförmigen Endabschnitt 9 auf. In dem dargestellten Ausführungsbeispiel erstreckt sich der Endabschnitt 9 über ca. 75% der Höhe der Noppen 7. Dementsprechend verjüngen sich die Noppen 7 in Richtung ihres freien Endes. In Fig. 4 ist auch erkennbar, dass die elastische Zwischenlage 2 dicker als die Höhe der Noppen 7 ist. Das bedeutet, dass das freie Ende der Noppen 7 bezüglich der Oberseite 10 der elastischen Zwischenlage 2 vertieft angeordnet ist. Dementsprechend ist zwischen der Oberseite 10 der elastischen Zwischenlage 2 und dem freien Ende der Noppen 7 in senkrechter Richtung ein bestimmter, festgelegter Abstand vorhanden. In dem dargestellten Ausführungsbeispiel beträgt dieser Abstand 2,5 mm. Fig. 4 is an enlarged detail view of the sectioned view of Fig. 3 in the region of a nub 7. The nubs 7 have a cylindrical portion 8 and an adjoining truncated conical end portion 9. In the illustrated embodiment, the end portion 9 extends over about 75% of the height of the studs 7. Accordingly, the studs 7 taper in the direction of their free end. In Fig. 4 It can also be seen that the elastic intermediate layer 2 is thicker than the height of the knobs 7. This means that the free end of the studs 7 is recessed with respect to the top 10 of the elastic intermediate layer 2. Accordingly, between the top 10 of the elastic intermediate layer 2 and the free end of the studs 7 in the vertical direction, a certain, predetermined distance is present. In the illustrated embodiment, this distance is 2.5 mm.

Die konische Form der Noppen 7 wurde so gewählt, dass lediglich eine geringe Kippbewegung der Schiene ermöglicht wird. Eine weitere oder größere Verkippung wird durch die Noppen 7 der Noppenplatte 3 verhindert. Ein Kippen der Schiene ist nur solange möglich, bis die Unterseite des Schienenfußes auf der Oberseite der Noppen 7 aufliegt. In diesem Zustand ist ein weiteres Absinken der Schiene nicht möglich, wodurch die Kipp- und/oder Drehbewegung begrenzt wird. Die spezielle Form der Endabschnitte 9 begrenzt dabei progressiv die Kippbewegung, während die Zwischenlage 2 eine vertikale Bewegung, d. h. ein Einsinken, einer Schienenfahrbahn ermöglicht. Die zylinderförmigen Durchgangslöcher 6 der Zwischenlage 2 verhindern eine Beschädigung der flächigen Zwischenlage 2 durch die Noppen 7 bei auftretenden Lasten. Andererseits ermöglicht die in Fig. 4 gezeigte Form der Noppen 7 und der Durchgangslöcher 6 eine gewisse vertikale Einsenkung der elastischen Zwischenlage 2. Beim Auftreten vertikaler Lasten wird die elastische Zwischenlage 2 somit elastisch verformt, ohne dass ein Verkippen auftritt, wenn gleichzeitig eine horizontale Kraft bzw. eine Kraft mit einer horizontal wirkenden Komponente vorhanden ist.The conical shape of the nubs 7 was chosen so that only a slight tilting movement of the rail is made possible. Another or larger tilting is prevented by the knobs 7 of the stud plate 3. A tilting of the rail is only possible until the bottom of the rail foot rests on the top of the knobs 7. In this state, a further lowering of the rail is not possible, whereby the tilting and / or rotational movement is limited. The special shape of the end portions 9 thereby progressively limits the tilting movement, while the intermediate layer 2 permits a vertical movement, ie sinking, of a rail track. The cylindrical through-holes 6 of the intermediate layer 2 prevent damage to the flat intermediate layer 2 by the knobs 7 when loads occur. On the other hand, the in Fig. 4 shown form of the studs 7 and the through-holes 6 a certain vertical depression of the elastic intermediate layer 2. When vertical loads occur, the elastic intermediate layer 2 is thus elastically deformed without tilting occurs when simultaneously a horizontal force or a force with a horizontally acting Component is present.

Die in den Fig. 1 bis 4 gezeigte Anordnung ist Bestandteil einer Schienenfahrbahn. Die Schienenfahrbahn umfasst eine Schiene, die mittels Schienenbefestigungen auf einer Schwelle angeordnet ist, wobei die elastische Zwischenlage 2 zwischen der Schiene und der Schwelle angeordnet ist. Die elastische Zwischenlage 2 kann dazu kraft- und/oder formschlüssig mit der Schwelle verbunden werden. Beispielsweise kann die elastische Zwischenlage mit der Schwelle verschraubt oder auf die Schwelle geklebt sein. Neben der beschriebenen Ausführung der Noppen als Bestandteil einer Noppenplatte können die Noppen alternativ auch an der Oberseite einer Betonschwelle angeformt sein. Die in diesem Ausführungsbeispiel beschriebene Anordnung ist unter anderem zur Lagerung einer Fahrbahn für Straßenbahnen und/oder Fernbahnen vorgesehen.The in the Fig. 1 to 4 The arrangement shown is part of a railroad track. The rail track comprises a rail, which is arranged by means of rail fasteners on a threshold, wherein the elastic intermediate layer 2 is arranged between the rail and the threshold. The elastic intermediate layer 2 can be positively and / or positively connected to the threshold. For example, the elastic intermediate layer may be screwed to the threshold or glued to the threshold. In addition to the described embodiment of the knobs as part of a studded panel, the studs may alternatively be formed on the top of a concrete sleeper. The arrangement described in this embodiment is provided inter alia for the storage of a roadway for trams and / or long-distance trains.
