Description

Die Erfindung betrifft eine Schwellenblockeinheit für Eisenbahnschienensysteme, bestehend aus einem Schwellenblock und einem diesen Schwellenblock teilweise umgebenden Schwellenschuh, wobei der Schwellenblock einen Kopfbereich und einen Fussbereich mit Seitenwandflächen und einer Bodenfläche aufweist und wobei der Kopfbereich länger und breiter ist als der Fussbereich, derart, dass zwischen dem Kopfbereich und dem Fussbereich ein Absatz besteht, der eine Anlagefläche bildet, die bereichsweise mindestens annähernd parallel zur Bodenfläche orientiert ist.The invention relates to a sleep block unit for railroad track systems, comprising a sleep block and a threshold shoe partially surrounding this sleep block, the sleep block having a head area and a foot area with side panels and a bottom surface, and wherein the head area is longer and wider than the foot area such that between the head area and the foot area a paragraph that forms a contact surface, which is partially oriented at least approximately parallel to the bottom surface.

Schwellenblockeinheiten werden bei so genannten festen Fahrbahnen verwendet, die zunehmend den so genannten Schotterfahrbahnen vorgezogen werden, weil damit die Leistung der Fahrbahn hinsichtlich der erreichbaren Geschwindigkeiten erhöht und die Instandhaltungskosten reduziert werden. Solche Schwellenblockeinheiten weisen einen im Allgemeinen aus Beton bestehenden Block auf, einen im Allgemeinen aus geformten Gummi bestehenden Schuh, der den Block aufnimmt, sowie einen elastischen Elastomerdämpfer, der zwischen dem Boden des Blockes und dem Boden des Schuhs angeordnet ist. Oben auf dem Block ist ein Befestigungssystem für eine Schiene angeordnet. Der Schuh wird mit Beton eingegossen.Threshold block units are used in so-called fixed carriageways, which are increasingly preferred to the so-called gravel lanes, because it increases the performance of the roadway in terms of achievable speeds and reduces maintenance costs. Such sleeper block assemblies include a generally concrete block, a generally molded rubber shoe that receives the block, and a resilient elastomeric damper disposed between the bottom of the block and the bottom of the shoe. On top of the block, a mounting system for a rail is arranged. The shoe is poured with concrete.

Im Patent DE10196374B4 ist dargelegt, dass bei solchen Schwellenblockeinheiten das Verhältnis zwischen der dynamischen und der statischen Steife mit der senkrechten Bewegung des Blockes steigt und somit die Verformung des Elastomerdämpfers unter dynamischer Last durch eine Berührungsfläche zwischen dem Block und der Schuhwand behindert wird und dass diese Berührungsfläche ein als Keileffekt bekanntes Phänomen ist. Das genannte Patent beschreibt sodann eine Lösung, um den Keileffekt zu eliminieren ohne den lateralen Widerstand des Gleises zu reduzieren und das Verhältnis zwischen dynamischer und statischer Steife zu verringern. Es ist offensichtlich, dass die Steife und das Dämpfungsverhalten einer Schwellenblockeinheit nachteilig beeinflusst wird, wenn Wasser, Staub, Schmutz, Betonmilch oder dergleichen zwischen den Block und den Schuh eindringt, ganz besonders dann, wenn eingedrungenes Wasser gefriert. Es wurden daher schon Massnahmen vorgeschlagen, um den Raum Zwischen Block und Schuh nach aussen hin abzudichten.In the patent DE10196374B4 For example, in such threshold block units, the relationship between dynamic and static stiffness increases with vertical movement of the block, and thus deformation of the elastomeric damper under dynamic load increases Contact surface between the block and the shoe wall is hindered and that this contact surface is a known wedge effect phenomenon. The cited patent then describes a solution to eliminate the wedge effect without reducing the lateral resistance of the track and reducing the ratio between dynamic and static stiffness. It is obvious that the stiffness and damping behavior of a sleep block unit is adversely affected when water, dust, dirt, concrete milk or the like penetrates between the block and the shoe, especially when infiltrated water freezes. Measures have therefore already been proposed to seal the space between block and shoe outwards.

Die Dokumente EP1017906B1 , DE4335516A1 und FR2684489A1 zeigen jeweils einen Schwellenblock mit einem diesen teilweise umgebenden Schwellenschuh, wobei am oberen Rand des Schwellenschuhs eine an der im Wesentlichen vertikal orientierten Aussenwand des Schwellenblocks anliegende elastische Dichtlippe angeordnet ist. Diese Anordnungen haben den Nachteil, dass bei den vertikalen Bewegungen des Schwellenblocks die Dichtlippe an der Aussenwand des Schwellenblocks reibt und dadurch einer Abnutzung unterworfen ist, wodurch die Dichtwirkung mit der Zeit nachlässt. Im Dokument EP0915202A1 ist eine Anordnung mit einem Schwellenblocks und einem Schwellenschuh beschrieben, wobei letzterer am oberen Rand eine umlaufende Dichtungsanordnung aufweist, die in eine eigens dafür vorgesehene, umlaufende Nut im Schwellenblock dichtend eingreift. Diese Nut erschwert die Herstellung des Schwellenblocks. Schliesslich beschreibt die Patentanmeldung FR2840330A1 eine Anordnung mit einem Schwellenblock und einem Schwellenschuh, wobei letzterer am oberen Rand eine relativ komplizierte Dichtanordnung aufweist, die unter Zuhilfenahme einer fliessfähigen Dichtmaterials erstellt wird. Bei der Betonschwelle gemäss EP1006239A1 greift der obere Rand des Schwellenschuhs vertikal in eine an einem Absatz des Schwellenblocks vorgesehene Nut ein und ist dadurch beim Einfedern des Schwellenblocks ebenfalls einer relativ starken Reibung ausgesetzt.The documents EP1017906B1 . DE4335516A1 and FR2684489A1 each show a threshold block with a this partially surrounding threshold shoe, wherein at the upper edge of the threshold shoe on the substantially vertically oriented outer wall of the threshold block fitting elastic sealing lip is arranged. These arrangements have the disadvantage that during the vertical movements of the sleeper block, the sealing lip rubs against the outer wall of the sleeper block and is thus subject to wear, as a result of which the sealing effect decreases over time. In the document EP0915202A1 an arrangement with a threshold block and a threshold shoe is described, the latter having at the upper edge a circumferential sealing arrangement which sealingly engages in a specially provided, circumferential groove in the sleeper block. This groove complicates the manufacture of the threshold block. Finally, the patent application describes FR2840330A1 an arrangement with a threshold block and a threshold shoe, the latter at the top of a having relatively complicated sealing arrangement, which is created with the aid of a flowable sealing material. In the concrete sleeper according to EP1006239A1 engages the upper edge of the sleeper shoe vertically in a provided on a shoulder of the threshold block groove and is thereby also exposed to a relatively strong friction during compression of the threshold block.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, eine Schwellenblockeinheit der eingangs genannten Art anzugeben, bei welcher die Dichtungsanordnung einfach aufgebaut und trotzdem im Betrieb einer geringen Abnutzung unterworfen ist.Based on this prior art, the invention is based on the object to provide a threshold block unit of the type mentioned, in which the seal assembly is simple and yet subjected to low wear during operation.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass am oberen Rand des Schwellenschuhs eine umlaufende Dichtlippe angeordnet ist, deren freies Ende nach oben und aussen gerichtet ist und von unten an der durch den Absatz gebildeten Anlagefläche anliegt.This object is achieved according to the invention that a circumferential sealing lip is arranged at the upper edge of the sleeper shoe whose free end is directed upwards and outwards and rests from below on the abutment surface formed by the shoulder.

Diese erfindungsgemässe Lösung hat insbesondere den Vorteil, dass die Dichtlippe bei vertikalen Bewegungen des Schwellenblocks im Schwellenschuh durch den Absatz im Wesentlichen vertikal im elastischen Bereich deformiert wird und nicht wie bei bekannten Schwellenblockeinheiten an einer Aussenwand des Schwellenblocks reibt. Dadurch wird die Dichtlippe weniger abgenützt, wodurch die Dichtwirkung länger aufrechterhalten wird und die Schwellenblockeinheit eine längere Lebensdauer hat.This solution according to the invention has the particular advantage that the vertical direction of the threshold block in the sleeper shoe deforms the sealing lip substantially vertically in the elastic region and does not rub against an outer wall of the sleeper block as in the case of known threshold block units. As a result, the sealing lip is less worn, whereby the sealing effect is maintained longer and the threshold block unit has a longer life.

Nach einer Ausführungsart ist ein Übergangsbereich zwischen Seitenwänden des Fussbereichs und dem Absatz gerundet. In diese Rundung fügt sich vorteilhaft die Dichtlippe ein, so dass eine relativ grosse Berührungsfläche zwischen der Dichtlippe und dem Schwellenblock besteht.In one embodiment, a transition region between sidewalls of the foot area and the heel is rounded. In this rounding fits the advantageous Sealing lip, so that there is a relatively large contact surface between the sealing lip and the threshold block.

Gemäss einer weiteren Ausführungsart ist am Schwellenschuh im Fussbereich der Dichtlippe eine umlaufende, nach aussen gerichtete Nase angeordnet. Diese Nase dient einerseits als Indikator für das Niveau des Betons, mit dem die Schwellenblockeinheit einzugiessen ist, andererseits bildet die Nase eine stabile Basis für die Dichtlippe.According to a further embodiment, a circumferential, outwardly directed nose is arranged on the threshold shoe in the foot region of the sealing lip. This nose, on the one hand, serves as an indicator of the level of the concrete with which the threshold block unit is to be enclosed, on the other hand, the nose forms a stable base for the sealing lip.

Schliesslich ist nach einer zusätzlichen Ausführungsart vorgesehen, dass sowohl der Fussbereich des Schwellenblocks als auch der Schwellenschuh von oben nach unten in der Länge und Breite abnehmen. Dadurch wird ein Austausch der einbetonierten Schwellenblockeinheit ohne Aufbrechen des umgebenden Betons möglich.Finally, according to an additional embodiment, it is provided that both the foot region of the sleeper block and the sleeper shoe decrease in length and width from top to bottom. As a result, an exchange of the embedded threshold block unit without breaking the surrounding concrete is possible.

Ein Ausführungsbeispiel der Erfindung wird nachstehend unter Bezugnahme auf die angefügten Zeichnungen beispielsweise näher beschrieben. Es zeigt

Figur 2
eine teilweise geschnittene Ansicht auf die kurze Seite der gleichen Schwellenblockeinheit und

eine Einzelheit aus Figur 1 bzw. 2 in einem vergrösserten Massstab.
An embodiment of the invention will be described below, for example, with reference to the accompanying drawings. It shows
FIG. 1
a partially sectioned view of the long side of a threshold block unit;
FIG. 2
a partially sectioned view of the short side of the same threshold block unit and
FIG. 3
a detail FIG. 1 or 2 on an enlarged scale.

Die Figuren 1 und 2 zeigen jeweils eine teilweise aufgeschnittene Seitenansicht eines Ausführungsbeispiels einer erfindungsgemässen Schwellenblockeinheit 1, mit Blick einmal auf die lange und einmal auf die kurze Seite der Schwellenblockeinheit 1, die einen im Wesentlichen rechteckigen Grundriss hat. Die Schwellenblockeinheit 1 entspricht bis auf die weiter unten beschriebene Dichtlippe 14 derjenigen, die im Dokument DE10196374B4 beschrieben ist und besteht aus einem Schwellenblock 2 aus Beton und einem diesen auf einem Teil seiner Höhe umgebenden Schwellenschuh 3 aus elastomerem Material, vorzugsweise aus Gummi. Der Schwellenblock 2 hat einen Kopfbereich 4 mit einer Auflagefläche 5 für Schienenbefestigungsmittel (nicht dargestellt). Ausserdem hat der Schwellenblock 2 einen Fussbereich 6, der kürzer und schmaler ist als der Kopfbereich 4, so dass zwischen dem Kopfbereich 4 und dem Fussbereich 6 ein Absatz 10 besteht. Die Seitenwandflächen 7 des Fussbereichs 6 sind leicht geneigt, so dass die Länge und Breite des Fussbereichs 6 nach unten abnehmen. Damit wird das Austauschen der Schwellenblockeinheit 1 ermöglicht, ohne dass der umgebende Beton aufgebrochen werden muss. Mit 8 ist die Bodenfläche des Schwellenblocks 2 bezeichnet. Der genannte Absatz 10 bildet eine umlaufende, im aussenliegenden Bereich mindestens annähernd parallel zur Bodenfläche 8 orientierte Anlagefläche, deren Funktion nachstehend noch beschrieben wird. Der Übergangsbereich 9 zwischen den Seitenwandflächen 7 und dem Absatz 10 ist vorzugsweise wie dargestellt gerundet.The Figures 1 and 2 each show a partially cutaway side view of an embodiment of an inventive threshold block unit 1, with a view once on the long and once on the short side of the threshold block unit 1, which has a substantially rectangular plan. The threshold block unit 1 corresponds to those described in the document except for the sealing lip 14 described below DE10196374B4 is described and consists of a threshold block 2 made of concrete and a surrounding this on a portion of its height threshold shoe 3 made of elastomeric material, preferably made of rubber. The threshold block 2 has a head portion 4 with a bearing surface 5 for rail fastening means (not shown). In addition, the threshold block 2 has a foot region 6 which is shorter and narrower than the head region 4, so that a heel 10 exists between the head region 4 and the foot region 6. The side wall surfaces 7 of the foot portion 6 are slightly inclined, so that the length and width of the foot portion 6 decrease downward. Thus, the replacement of the threshold block unit 1 is made possible without the surrounding concrete has to be broken. With 8, the bottom surface of the threshold block 2 is designated. Said paragraph 10 forms a circumferential, in the outer region at least approximately parallel to the bottom surface 8 oriented contact surface, whose function will be described below. The transition region 9 between the side wall surfaces 7 and the shoulder 10 is preferably rounded as shown.

Der Schwellenschuh 3 weist vier Seitenwände 11 und einen Boden 12 auf und zwischen der Bodenfläche 8 des Schwellenblocks 2 und dem Boden 12 des Schwellenschuhs 3 ist eine elastische Einlage 15 angeordnet, die im Betrieb unter Last eine vertikale Bewegung des Schwellenblocks 2 im Schwellenschuh 3 zulässt. An den Aussenwänden 11 des Schwellenschuhs 3 ist eine horizontal verlaufende Nase 13 angeordnet, die beim Einbetonieren der Schwellenblockeinheit 1 als Orientierung für das einzuhaltende Niveau des Betons dient, das in den Figuren 1 und 2 mit der Linie 16 angegeben ist.The threshold shoe 3 has four side walls 11 and a bottom 12 and between the bottom surface 8 of the threshold block 2 and the bottom 12 of the threshold shoe 3, an elastic insert 15 is arranged, which allows a vertical movement of the threshold block 2 in the threshold shoe 3 during operation under load. On the outer walls 11 of the threshold shoe 3 is a horizontally extending nose thirteenth arranged in the concreting of the threshold block unit 1 as an orientation for the level of concrete to be maintained, which in the Figures 1 and 2 indicated by line 16.

Wie die Ausschnittsvergrösserung in Figur 3 besonders deutlich zeigt, ist am oberen Rand des Schwellenschuhs 3 eine umlaufende Dichtlippe 14 angeordnet, deren freies Ende nach aussen gerichtet ist und von unten an der durch den Absatz 10 gebildeten Anlagefläche anliegt. Im Betrieb, wenn sich der Schwellenblock 2 unter Einfederung der Einlage 15 vertikal bewegt, wird die Dichtlippe 14 durch die Anlagefläche federnd umgebogen, wobei sie stets den Kontakt mit der Anlagefläche hält und dadurch den Zwischenraum zwischen dem Schwellenschuh 3 und dem Schwellenblock 2 zuverlässig abdichtet. Durch das federnde Umbiegen entsteht verhältnismässig wenig Reibung zwischen der Dichtlippe 14 und dem Schwellenblock 2, so dass die erfindungsgemässe Schwellenblockeinheit 1 trotz einem einfacheren Aufbau eine höhere Lebensdauer hat als bekannte Schwellenblockeinheiten.Like the magnification in FIG. 3 shows particularly clearly, at the upper edge of the threshold shoe 3, a circumferential sealing lip 14 is arranged, whose free end is directed outwards and rests from below on the contact surface formed by the shoulder 10. In operation, when the threshold block 2 moves vertically under deflection of the insert 15, the sealing lip 14 is resiliently bent by the contact surface, always keeping in contact with the contact surface and thereby reliably seals the gap between the threshold shoe 3 and the threshold block 2. The resilient bending results in relatively little friction between the sealing lip 14 and the sleeper block 2, so that the inventive threshold block unit 1 despite a simpler structure has a longer life than known threshold block units.
