Description

Die Erfindung betrifft gemäß Patentanspruch 1 eine Weiche für Eisenbahnanlagen mit einer ersten und einer zweiten Flügelschiene, mit einem Herzstück, dessen Spitze zwischen einer ersten, an der ersten Flügelschiene anliegenden Stellung und einer zweiten, an der zweiten Flügelschiene anliegenden Stellung beweglich ist, mit einer Auflagefläche zur Abstützung der Herzstückspitze, mit einem Bügel, mit Laufbahnen und mit Rollen, wobei die Herzstückspitze auf dem Bügel aufliegt, der außerhalb der ersten und der zweiten Flügelschiene jeweils auf einer der Rollen gelagert ist, wobei die Rollen jeweils auf einer der Laufbahnen abrollen und mindestens eine Laufbahn abgesenkte Endabschnitte aufweist, um die Herzstückspitze bei der Bewegung zwischen der ersten Stellung und der zweiten Stellung anzuheben.The invention relates to a switch for railway systems with a first and a second wing rail, with a centerpiece, the tip of which is movable between a first, adjacent to the first wing rail position and a second, adjacent the second wing rail position, with a support surface for supporting the frog point, with a bracket, with raceways and with rollers, wherein the frog point rests on the bracket, which is mounted outside of the first and the second wing rail respectively on one of the rollers, wherein the rollers each roll on one of the tracks and at least a raceway has lowered end portions to lift the frog point in the movement between the first position and the second position.

Weichen von untergeordneten Gleisanlagen werden in der Regel mit starren Herzstücken ausgestattet, was eine technisch besonders einfache Lösung ist, aber im Fahrbetrieb Nachteile mit sich bringt. Aufgrund der unterbrochenen Fahrkante sind solche Weichen weder für hohe Achslasten noch für höhere Geschwindigkeiten geeignet. Um diese Nachteile zu vermeiden sind Herzstücke mit beweglichen Spitzen entwickelt worden, die sich je nach Stellung der Weiche an die eine oder die andere Flügelschiene anlegen. Mit solchen Weichen ist es möglich eine geschlossene Fahrkante darzustellen, so dass solche Weichen auch für höhere Belastungen und höhere Fahrgeschwindigkeiten geeignet sind.Turnouts of subordinate track systems are usually equipped with rigid frogs, which is a technically particularly simple solution, but brings disadvantages when driving. Due to the interrupted running edge, such switches are neither suitable for high axle loads nor for higher speeds. In order to avoid these disadvantages, frogs with moving tips have been developed which, depending on the position of the switch, rest against one or the other wing rail. With such switches, it is possible to represent a closed edge, so that such switches are also suitable for higher loads and higher speeds.

Eine einfache Lösung, eine bewegliche Herzstückspitze darzustellen, besteht darin, Gleitplatten vorzusehen auf denen die Herzspitze von der ersten Stellung in die zweite Stellung gleitet. Solche Gleitplatten müssen aber regelmäßig geschmiert werden, was einerseits einen erhöhten Arbeitsaufwand bedeutet und andererseits aus Umweltgesichtspunkten bedenklich ist. Darüber hinaus sind die Stellkräfte einer solchen Lösung groß. Im Lichte dieser Probleme sind so genannte Herzstückhebevorrichtungen bekannt geworden, bei denen die Herzstückspitze im Bewegungsbereich angehoben wird und auf Rollen geführt wird, so dass auch ohne Schmierung eine entsprechende Verringerung der Reibung erzielt wird. In den Endstellungen wird jedoch die Herzstückspitze wiederum auf eine Auflagefläche abgesenkt, um die beim Überfahren der Weiche entstehenden Belastungen nicht auf die Rolle, sondern auf die Auflagefläche abzuleiten, so dass eine unzulässige Belastung der Rollen vermieden wird.A simple solution to represent a movable frog point is to provide sliding plates on which the heart tip slides from the first position to the second position. However, such sliding plates must be lubricated regularly, which means on the one hand an increased workload and on the other hand is environmentally dubious. In addition, the restoring forces of such a solution are great. In the light of these problems so-called heart lift devices are known in which the frog point is raised in the range of motion and is guided on rollers, so that a corresponding reduction of the friction is achieved without lubrication. In the end positions, however, the frog tip is again lowered onto a bearing surface in order not to divert the loads arising when passing over the switch to the roller, but rather to the bearing surface, so that an impermissible loading of the rollers is avoided.

Eine solche Lösung ist aus der DE 102 15 280 B bekannt. Dabei ist eine Rolle unterhalb der Herzstückspitze angeordnet, um diese anzuheben und zu führen. Nachteilig bei dieser Lösung ist jedoch, dass Grund des erforderlichen Bauraumes relativ umfangreiche konstruktive Vorkehrungen erforderlich sind, so dass nur neue Weichen in sinnvoller Weise mit dieser Vorrichtung ausgestattet werden können.Such a solution is out of the DE 102 15 280 B known. In this case, a roller is arranged below the frog point to raise and guide them. The disadvantage of this solution, however, is that the reason for the required installation space relatively extensive design precautions are required, so that only new points can be fitted in a meaningful way with this device.

Aus der ES 2 265 237 A ist eine Lösung bekannt, die einen Teil der oben beschriebenen Nachteile beseitigt. Dabei ist die Herzstückspitze auf einem Bügel gelagert, der auf Rollen geführt ist. Durch eine besondere Ausbildung der Laufbahn, die auf den Rollen abläuft, wird erreicht, dass die Herzstückspitze nur bei der Bewegung zwischen der ersten und der zweiten Stellung von einer Auflagefläche abgehoben wird, um die Reibung zu verringern. Der Bügel wird dabei durch Ausnehmungen in den Flügelschienen hindurchgeführt und ist auf Rollen gelagert, die zumindest teilweise unterhalb der Flügelschienen angeordnet sind. Diese Lösung ist konstruktiv aufwendig, benötigt viel Bauraum und ist für die Nachrüstung bestehender Weichen nicht geeignet. Darüber hinaus ist nicht sichergestellt, dass die Herzstückspitze in ihren Endlagen gegen die Flügelschienen angepresst wird, um undefinierte Stellungen sicher zu vermeiden.From the ES 2 265 237 A For example, a solution is known which overcomes some of the disadvantages described above. The frog tip is mounted on a bracket, which is guided on rollers. By a special design of the raceway, which runs on the rollers, it is achieved that the frog tip is lifted only on the movement between the first and the second position of a bearing surface in order to reduce the friction. The bracket is thereby passed through recesses in the wing rails and is mounted on rollers, which are arranged at least partially below the wing rails. This solution is structurally complex, requires a lot of space and is not suitable for retrofitting existing points. In addition, it is not ensured that the frog point is pressed in their end positions against the wing rails to safely avoid undefined positions.

Ferner ist aus der DE 43 15 559 A eine Lösung bekannt, die eine Vielzahl von Teilen aufweist.Furthermore, from the DE 43 15 559 A a solution is known which has a plurality of parts.

Aufgabe der vorliegenden Erfindung ist es, eine Lösung anzugeben, mit der die Reibungsverhältnisse bei Herzstückspitzen im obigen Sinn optimiert werden können, es aber gleichzeitig möglich ist, bestehende Weichen nachzurüsten. Eine weitere Aufgabe der vorliegenden Erfindung ist es, eine Lösung anzugeben, bei der die Herzstückspitze in ihren Endlagen automatisch gegen die Flügelschienen angepresst wird, ohne dass dafür gesonderte Bauteile oder Maßnahmen erforderlich sind.Object of the present invention is to provide a solution with which the friction conditions can be optimized at frog points in the above sense, but it is also possible to retrofit existing switches. Another object of the present invention is to provide a solution in which the frog point is automatically pressed in its end positions against the wing rails, without the need for separate components or measures are required.

Erfindungsgemäß werden diese Aufgaben durch die Merkmale von Patentanspruch 1 gelöst. Insbesondere ist vorgesehen, dass der Bügel die erste und die zweite Flügelschiene untergreift und dass der Bügel eine Basis besitzt, die in ihrem mittleren Bereich eine Aufnahme für das Herzstück aufweist, um die Kräfte beim Stellen der Weiche über den Bügel ohne Zwischenschaltung weiterer Bauteile zu übertragen, und dass die Basis gegenüber seitlich anschließenden Auflageabschnitten abgesenkt ist.According to the invention, these objects are achieved by the features of claim 1. In particular, it is provided that the bracket engages under the first and second wing rail and that the bracket has a base having in its central region a receptacle for the heart to transmit the forces when setting the switch on the bracket without the interposition of other components , and that the base is lowered relative to laterally adjoining support sections.

Wesentlich an der vorliegenden Erfindung ist, dass die Rollenlagerung räumlich von der Herzstückspitze entkoppelt ist und somit unterhalb des Herzstückes bzw. der Flügelschienen nur minimaler Platzbedarf entsteht. Wesentlich an der Erfindung ist insbesondere, dass Gleitführungen vollständig vermieden werden, da der Bügel ausschließlich auf Rollen läuft. Auch die direkte Übertragung der Kräfte über den Bügel ohne Zwischenschaltung weiterer Bauteile ist eine Eigenheit der Erfindung.An essential feature of the present invention is that the roller bearing is spatially decoupled from the frog tip and thus only minimal space is required below the heart piece or the wing rails. Essential to the invention is in particular that sliding guides are completely avoided, since the bracket runs exclusively on rollers. Also the direct transfer of forces over the bracket without the interposition of other components is a peculiarity of the invention.

Eine besonders begünstigte Ausführungsvariante der Erfindung sieht vor, dass die Laufbahn einen erhabenen Abschnitt aufweist, der von Anpresskanten begrenzt ist, an denen die Rolle in der ersten bzw. der zweiten Stellung anliegt. Der erhabene Abschnitt ist somit von den abgesenkten Endabschnitten begrenzt, wobei die Anpresskanten dazu dienen, die Herzstückspitze in der ersten bzw. zweiten Stellung, also den Endstellungen, an die Flügelschiene anzupressen. Je nach den speziellen Umständen können die Anpresskanten auch als Rampen ausgebildet sein.A particularly favorable embodiment variant of the invention provides that the raceway has a raised portion, which is delimited by contact pressure edges against which the roller rests in the first and the second position. The raised portion is thus limited by the lowered end portions, wherein the Anpresskanten serve to press the frog point in the first or second position, ie the end positions, to the wing rail. Depending on the specific circumstances, the Anpresskanten can also be designed as ramps.

Ein besonders bedeutsamer Aspekt der vorliegenden Erfindung ist die Tatsache, dass der Bügel eine Basis besitzt, die in ihrem mittleren Bereich eine Aufnahme für das Herzstück aufweist und die gegenüber seitlich anschließenden Auflageabschnitten abgesenkt ist. Auf diese Weise ist es möglich, die Rollen für die Lagerung des Bügels seitlich neben den Flügelschienen anzuordnen, was eine besonders kompakte Lösung ergibt. Auch die Nachrüstung bestehender Weichen wird dadurch ermöglicht. Eine besonders kompakte und für die Nachrüstung besonders geeignete Lösung sieht vor, dass der Bügel zwischen zwei Schwellen angeordnet ist.A particularly significant aspect of the present invention is the fact that the bracket has a base which has in its central region a receptacle for the heart and which is lowered relative to laterally adjacent support portions. In this way it is possible to arrange the rollers for the storage of the bracket laterally next to the wing rails, resulting in a particularly compact solution. The retrofitting of existing points is made possible. A particularly compact solution, which is particularly suitable for retrofitting, provides that the stirrup is arranged between two sleepers.

In der Folge wird die vorliegende Erfindung anhand des in den Figuren dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

In the following, the present invention will be explained in more detail with reference to the embodiment shown in FIGS. Show it:

In an sich bekannter Weise ist ein Herzstück 1 mit seiner Spitze 1a beweglich zwischen einer ersten Flügelschiene 2 und einer zweiten Flügelschiene 3 gelagert. In der in den Figuren dargestellten Stellung liegt die Herzstückspitze 1a an der zweiten Flügelschiene 3 an. In dieser Stellung liegt die Herzstückspitze 1a auf einer Auflagefläche 4 auf, die die Kräfte aufnimmt, die beim Überfahren der Weiche auf das Herzstück 1 ausgeübt werden. Dies ist auch der Fall, wenn die Herzstückspitze 1a in der nicht dargestellten Stellung an der ersten Flügelschiene 2 anliegt.In a manner known per se, a frog 1 is movably mounted with its tip 1 a between a first wing rail 2 and a second wing rail 3. In the position shown in the figures, the frog point 1a abuts against the second wing rail 3. In this position, the frog tip 1a rests on a bearing surface 4, which absorbs the forces exerted on the frog 1 when the switch is passed over. This is also the case when the frog point 1a rests against the first wing rail 2 in the position not shown.

Unterhalb der Herzstückspitze 1a ist ein Bügel 5 angeordnet, der im Bereich einer Basis 6 die Herzstückspitze 1a und beide Flügelschienen 2 und 3 untergreift und im Bereich seitlich angeordneter Auflageabschnitte 7a und 7b auf Rollen 9a, 9b gelagert ist. An der Basis 6 ist ein Auflageabschnitt 8 vorgesehen, der die Herzstückspitze 1a von unten unterstützt. Die Basis 6 ist gegenüber den Auflageabschnitten 7a und 7b abgesenkt, so dass die Rollen 9a, 9b seitlich neben den Flügelschienen 2 und 3 angeordnet werden können.Below the frog point 1a, a bracket 5 is arranged, which engages in the region of a base 6, the frog point 1a and both wing rails 2 and 3 and in the region of laterally arranged support portions 7a and 7b on rollers 9a, 9b is stored. At the base 6, a support portion 8 is provided, which supports the frog point 1a from below. The base 6 is lowered relative to the support sections 7a and 7b, so that the rollers 9a, 9b can be arranged laterally next to the wing rails 2 and 3.

Jede der Rollen 9a, 9b ist auf einem fest mit dem Untergrund (z.B. den benachbarten Schwellen) verbundenen Lagerstuhl 10a, 10b gelagert. Die Laufbahnen 11a, 11b an der Unterseite der Auflageabschnitte 7a, 7b laufen jeweils in einer Nut 16 der Rollen 9a, 9b ab, um die Bewegung des Bügels 5 in Richtung des Doppelpfeils 12 zu ermöglichen.Each of the rollers 9a, 9b is mounted on a bearing block 10a, 10b fixedly connected to the ground (e.g., the adjacent sills). The raceways 11a, 11b on the underside of the support sections 7a, 7b each run in a groove 16 of the rollers 9a, 9b to allow the movement of the bracket 5 in the direction of the double arrow 12.

Die Auflageabschnitte 7a, 7b weisen an ihren Laufbahnen 11a, 11b jeweils einen rechteckigen Vorsprung 14a, 14b auf, der eine Breite B von beispielsweise 32 mm und eine Höhe H von beispielsweise 3 mm besitzt. Ein Verhältnis von etwa 1:10 zwischen Höhe H und Breite B hat sich als besonders günstig herausgestellt, wobei vorteilhafte Bereiche zwischen 1:5 und 1:20 liegen. Besonders bevorzugt ist es, wenn die Höhe H des Vorprungs 14a, 14b zwischen 8% und 12% seiner Breite B beträgt.The support sections 7a, 7b each have a rectangular projection 14a, 14b on their raceways 11a, 11b, which has a width B of, for example, 32 mm and a height H of, for example, 3 mm. A ratio of about 1:10 between height H and width B has been found to be particularly favorable, with advantageous ranges between 1: 5 and 1:20. It is particularly preferred if the height H of the projection 14a, 14b is between 8% and 12% of its width B.

Seitlich sind die rechteckigen Vorsprünge 14a, 14b von Anpresskanten 15 begrenzt, an die abgesenkte Endabschnitte 12a, 13a; 12b, 13b anschließen. Die Geometrie des Bügels 5 und der benachbarten Bauteile ist dabei so gewählt, dass in den Endstellungen die abgesenkten Endabschnitte 12a, 13a; 12b, 13b ohne wesentliche Belastung auf den Rollen 9a, 9b aufliegen, gleichzeitig aber das Herzstück auf der Auflagefläche 4 aufliegt und die Anpresskanten 15 an den Rollen 9a, 9b anliegen und so die jeweilige Position sichern. Um beim Stellen der Weiche das Herzstück 1 bzw. seine Spitze 1a in die jeweils andere Position zu bringen, muss der Bügel 5 zunächst angehoben werden, indem der rechteckige Vorsprung 14a, 14b auf die Rollen 9a, 9b aufläuft, wodurch gleichzeitig die Herzstückspitze 1a von der Auflagefläche 4 abgehoben wird. Dadurch ist die weitere Verstellung mit geringem Kraftaufwand möglich.Laterally, the rectangular projections 14a, 14b of pressing edges 15 are limited to the lowered end portions 12a, 13a; Connect 12b, 13b. The geometry of the bracket 5 and the adjacent components is chosen so that in the end positions, the lowered end portions 12a, 13a; 12b, 13b without substantial load on the rollers 9a, 9b rest, but at the same time the heart rests on the support surface 4 and the Anpresskanten 15 abut the rollers 9a, 9b and thus secure the respective position. In order to bring the core 1 and its tip 1a in the other position when placing the switch, the bracket 5 must first be raised by the rectangular projection 14a, 14b runs on the rollers 9a, 9b, thereby simultaneously the frog tip 1a of the support surface 4 is lifted. As a result, the further adjustment with little effort is possible.

Der Bügel 5 ist zwischen zwei benachbarten Schwellen 17a, 17b angeordnet, wobei der Freiraum zwischen den Schwellen 17a, 17b auch die Rollen 9a, 9b samt Lagerstuhl 10a, 10b aufnimmt.The bracket 5 is disposed between two adjacent sleepers 17a, 17b, wherein the space between the sleepers 17a, 17b and the rollers 9a, 9b including bearing block 10a, 10b receives.

Die vorliegende Erfindung ermöglicht es, eine Weiche mit beweglicher Herzstückspitze 1a mit geringem Aufwand und zuverlässiger Funktion darzustellen.The present invention makes it possible to represent a switch with movable frog point 1a with little effort and reliable function.
