Description

Schwellenblockeinheit für Eisenbahnechienensysteme  Threshold block unit for railroad track systems
Die Erfindung betrifft eine Schwellenblockeinheit für The invention relates to a threshold block unit for
Eisenbahnschienensysteme, bestehend aus einem Schwellenblock und einem diesen Schwellenblock teilweise umgebenden  Railway track systems, consisting of a threshold block and a threshold block partially surrounding this
Schwellenschuh, wobei der Schwellenblock einen Kopfbereich und einen Fussbereich mit Seitenwandflachen und einer Threshold shoe, wherein the threshold block has a head area and a foot area with side wall surfaces and a
Bodenfläche aufweist und wobei der Kopfbereich länger und breiter ist als der Fussbereich, derart, dass zwischen dem Kopfbereich und dem Fussbereich ein Absatz besteht. Floor area and wherein the head area is longer and wider than the foot area, such that between the head area and the foot area is a paragraph.
Schwellenblockeinheiten werden bei so genannten festen Fahrbahnen verwendet, die zunehmend den so genannten Threshold block units are used in so-called fixed carriageways, increasingly the so-called
Schotterfahrbahnen vorgezogen werden, weil damit die Schotterfahrbahnen be preferred because with it the
Leistung der Fahrbahn hinsichtlich der erreichbaren Performance of the roadway in terms of achievable
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 Speeds are increased and the maintenance costs are reduced. Such sill block units comprise a generally concrete block, a generally molded rubber shoe which receives the block and an elastic block

Der Schuh wird mit Beton eingegossen. Elastomer damper located 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 In patent DE10196374B4 it is stated that in such threshold block units the relationship between the
dynamischen und der statischen Steife mit der senkrechten Bewegung des Blockes steigt und somit die Verformung des Elastomerdämpfers unter dynamischer Last durch eine dynamic and static stiffness with the vertical movement of the block increases and thus the deformation of the elastomer damper under dynamic load by a

Es ist offensichtlich, dass die Steife und das Dämpfungsverhalten einer eliminate without reducing the lateral resistance of the track and reducing the ratio between dynamic and static stiffness. It is obvious that the stiffness and the damping behavior of a

Es wurden daher schon Threshold block unit is adversely affected when water, dust, dirt, concrete milk or the like penetrates between the block and the shoe, especially if infiltrated water freezes. It was therefore already
Massnahmen vorgeschlagen, um den Raum Zwischen Block und Schuh nach aussen hin abzudichten. Die Dokumente EP1017906B1 und DE4335516A1 zeigen beide einen Schwellenblock mit einem diesen teilweise umgebenden Measures proposed to seal the space between block and shoe outwards. The documents EP1017906B1 and DE4335516A1 both show a threshold block with a partially surrounding it
Schwellenschuh, wobei am oberen Rand des Schwellenschuhs eine an der im Wesentlichen vertikal orientierten Aussenwand des Schwellenblocks anliegende elastische Dichtlippe 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
angeordnet ist. Diese Anordnungen haben den Nachteil, dass bei den vertikalen Bewegungen des Schwellenblocks die is arranged. These arrangements have the disadvantage that in the vertical movements of the threshold block the
Dichtlippe an der Aussenwand des Schwellenblocks reibt und dadurch einer Abnutzung unterworfen ist, wodurch die Sealing lip rubs against the outer wall of the threshold block and is thus subject to wear, whereby the
Dichtwirkung mit der Zeit nachlässt. Im Dokument EP0915202A1 ist eine Anordnung mit einem Schwellenblock und einem Sealing effect wears off over time. In document EP0915202A1 there is an arrangement with a threshold block and a
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. Threshold described, the latter has at the top of a circumferential seal assembly 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 FR2840330A1 describes an arrangement with a threshold block and a threshold shoe, the latter having at the upper edge a relatively complicated sealing arrangement, the lower With the help of a flowable sealing material is created.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, eine Schwellenblockeinheit der eingangs genannten Art anzugeben, bei welcher die 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
Dichtungsanordnung einfach aufgebaut und trotzdem im Betrieb einer geringen Abnutzung unterworfen ist. Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass am oberen Rand des Schwellenschuhs eine umlaufende Dichtlippe angeordnet ist, die nach oben und aussen gerichtet ist und am Absatz anliegt. Diese erfindungsgemässe Lösung hat insbesondere den Vorteil, dass die Dichtlippe bei vertikalen Bewegungen des Sealing arrangement is simple and yet subject to low wear during operation. This object is achieved in that at the upper edge of the threshold shoe, a circumferential sealing lip is arranged, which is directed upwards and outwards and abuts the shoulder. This inventive solution has the particular advantage that the sealing lip in vertical movements of the
Schwellenblocks im Schwellenschuh durch den Absatz im Threshold blocks in the sleeper shoe through the heel in the
Wesentlichen vertikal im elastischen Bereich deformiert wird und nicht wie bei bekannten Schwellenblockeinheiten an einer Aussenwand des Schwellenblocks reibt. Dadurch wird die Is deformed substantially vertically in the elastic region and does not rub as in known threshold block units on an outer wall of the threshold block. This will be the
Dichtlippe weniger abgenützt, wodurch die Dichtwirkung länger aufrechterhalten wird und die Schwellenblockeinheit eine längere Lebensdauer hat. Nach einer Ausführungsart der Erfindung bildet der Absatz eine Anlagefläche, die bereichsweise mindestens annähernd parallel zur Bodenfläche orientiert ist. Diese Anlagefläche drückt beim Einfedern des Schwellenblocks im Schwellenschuh die Dichtlippe vertikal zusammen. Sealing lip less worn, whereby the sealing effect is maintained longer and the threshold block unit has a longer life. According to one embodiment of the invention, the shoulder forms a contact surface, which is partially oriented at least approximately parallel to the bottom surface. This contact surface presses the compression lip of the emerging block in the sleeper shoe vertically together.
Nach einer anderen 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 another embodiment, a transition region between sidewalls of the foot region 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 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 serves as an indicator of the level of the concrete with which the
Schwellenblockeinheit einzugiessen ist, andererseits bildet die Nase eine stabile Basis für die Dichtlippe. 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 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. This will be an exchange of

Die Figuren 1 und 2 zeigen jeweils eine teilweise Figures 1 and 2 each show a partial
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 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 is essentially one
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 rectangular floor plan has. The threshold block unit 1 corresponds, except for the sealing lip 14 described below, to that described in DE10196374B4 and consists of a concrete threshold block 2 and a threshold shoe 3 of elastomeric material, preferably of rubber, surrounding it over part of its height. The threshold block 2 has a head region 4 with a
Auflagefläche 5 für Schienenbefestigungsmittel (nicht dargestellt) . Ausserdem hat der Schwellenblock 2 einen Support surface 5 for rail fastening means (not shown). In addition, the threshold block 2 has a
Fussbereich 6, der kürzer und schmaler ist als der Foot area 6, which is shorter and narrower than the one
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 Head area 4, so that between the head area 4 and the foot area 6 a paragraph 10 is made. 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. The said paragraph 10 forms a circumferential, 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. outboard area 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 The threshold shoe 3 has four side walls 11 and a bottom 12 and between the bottom surface 8 of the
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 Sleeper blocks 2 and the bottom 12 of the threshold shoe 3, an elastic insert 15 is arranged, which in operation under load, a vertical movement of the threshold block 2 in
Schwellenschuh 3 zulässt. An den Aussenwänden 11 des Threshold shoe 3 allows. On the outside walls 11 of the
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. Threshold shoe 3 is a horizontally extending nose 13th arranged, which serves in the concreting of the threshold block unit 1 as an orientation for the level to be maintained of the concrete, which is indicated in the figures 1 and 2 with the 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 As the detail enlargement in Figure 3 shows particularly clearly, a circumferential sealing lip 14 is arranged at the upper edge of the threshold shoe 3, whose free end is directed outwards and abuts 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 replaced by the
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. Bearing surface resiliently bent, whereby it always keeps 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.
