Abstract
Description
Die Erfindung bezieht sich auf eine Rolleneinrichtung für eine einem ersten Schienenabschnitt wie Backenschiene zugeordneten, zu diesem entlang eines Verstellwegs verstellbaren und an diesem anlegbaren bzw. mit diesem verriegelbaren zweiten Schienenabschnitt wie Weichenzunge umfassend eine Unterlage wie Gleitstuhl für den zweiten Schienenabschnitt sowie diesem entlang des Verstellwegs zugeordnete und vorzugsweise von einer gemeinsamen Halterung ausgehende federnde oder federnd gelagerte Rollenelemente, auf die der zweite Schienenabschnitt zumindest während des Versteilens abstützbar ist.The invention relates to a roller device for a first rail section assigned like stock rail, adjustable to this along an adjustment path and on this second rail section that can be put on or locked like switch tongue comprising a pad like sliding chair for the second Rail section and assigned to it along the adjustment path and preferably resilient or resiliently mounted roller elements originating from a common holder, to which the second rail section at least during the adjustment is supported.
Eine entsprechende Rolleneinrichtung ist der EP 0 532 860 A1 zu entnehmen. Um sicherzustellen, daß eine Weichenzunge auch dann nicht auf einen Gleitstuhl schlägt, wenn eine Schwingungsanregung erfolgt, ist vorgesehen, daß die Rollenelemente auf zumindest zwei Federelemente unterschiedlicher Kennlinien abgestützt sind, wobei eines der Federelemente eine im wesentlichen konstante Steifigkeit und das andere Federelement eine veränderliche Steifigkeit aufweist. Dabei sind die Federelemente derart mechanisch miteinander gekoppelt, daß bei durch die Weichenzunge belasteten Rollenelementen jedes Federelement einen federfähigen Zustand aufweist.A corresponding roller device can be found in EP 0 532 860 A1. Around ensure that a switch tongue does not hit a sliding chair even then, if vibration is excited, it is provided that the roller elements on at least two spring elements of different characteristics are supported, one the spring elements have a substantially constant rigidity and the other spring element has a variable rigidity. The spring elements are such mechanically coupled to each other that with roller elements loaded by the switch tongue each spring element has a resilient state.
Durch diese Maßnahmen konnte erstmals sichergestellt werden, daß die Weichenzunge, sofern diese nicht verriegelt ist, bei Schwingungseinleitungen auf den Gleitstuhl nicht schlagen kann. These measures made it possible for the first time to ensure that the switch tongue, if this is not locked, not when vibrations are initiated on the sliding chair can beat.
Während des Verstellen, und zwar dann, wenn die Weichenzunge von der verriegelten in die geöffnete Stellung bewegt werden soll, können Kraftspitzen auftreten, die durch das Anfahren des Weichenzungenfußes auf die in etwa 5 mm über den Gleitstuhl vorstehenden Rollenelemente verursacht werden können; denn in verriegelter Stellung ruht die Weichenzunge nach dem Stand der Technik allein auf dem Gleitstuhl und wird erst nach dem Entriegeln und Verstellen der Weichenzunge von den erwähntermaßen im unbelasteten Zustand in etwa 5 mm über den Gleitstuhl vorstehenden Rollen erfaßt und durch diese angehoben.During the adjustment, namely when the switch tongue is locked by the In the open position is to be moved, force peaks can occur that moving the switch tongue foot to the in about 5 mm above the sliding chair protruding roller elements can be caused; because in the locked position According to the prior art, the switch tongue rests and is alone on the sliding chair only after unlocking and adjusting the switch tongue from the mentioned in unloaded condition in about 5 mm above the sliding chair and protruding rollers raised by this.
Aus der DD 56 536 ist eine Weichenzungenrolleneinrichtung bekannt, die mit einer Rolle verbunden ist, die beim Verschieben der Weichenzunge auf einer Fläche abrollt.From DD 56 536 a switch tongue roller device is known, which with a Roll is connected, which rolls on a surface when moving the switch tongue.
Nach der DE-AS 10 56 641 wird eine Weichenzunge auf einer Stützrolle verfahren, die im erheblichen Umfang über einen Lagerbock vorsteht.According to DE-AS 10 56 641 a switch tongue is moved on a support roller, the protrudes to a considerable extent over a pedestal.
Bei einer Weichenzungenrollvorrichtung nach der DD 61 558 wird eine Weichenzunge auf Rollen abgestützt, um die Gleitreibung beim Verstellen zu reduzieren. With a switch tongue rolling device according to DD 61 558, a switch tongue is used supported on rollers to reduce sliding friction when adjusting.
Aus der AU-B- 0 552 880 ist eine Rolleneinrichtung der eingangs beschriebenen Art bekannt, bei der eine zu einer Backenschiene verstellbare Zunge stets auf Rollen abgestützt ist, sei es, dass die Zunge unmittelbar auf den Rollen aufliegt oder diese sich ihrerseits auf einen Gleitstuhl abstützen. Da die Weichenzunge stets auf den Rollen ruht, erfolgt eine punktuelle Abstützung, die zu starken Belastungen der Rollen führen kann.A roller device of the type described at the outset is known from AU-B-0 552 880, in which a tongue adjustable to a stock rail is always supported on rollers, be it that the tongue rests directly on the castors or that the turn is on a sliding chair support. Since the switch tongue always rests on the rollers, there is a selective one Support that can lead to heavy loads on the rollers.
Der vorliegenden Erfindung liegt das Problem zugrunde, eine Rolleneinrichtung der eingangs beschriebenen Art derart weiterzubilden, daß mögliche Kraftsritzen beim Umstellen des zu dem ersten Schienenabschnitt verstellbaren zweiten Schienenabschnitts unterbunden bzw. reduziert werden, sofern dieser auf Rollenelementen abgestützt werden soll.The present invention is based on the problem of a roller device at the beginning described type in such a way that possible scratches in power when changing the the second rail section adjustable to the first rail section is prevented or can be reduced if this is to be supported on roller elements.
Das Problem wird erfindungsgemäß dadurch gelöst, daß der zweite Schienenabschnitt in an dem ersten Schienenabschnitt anliegender Stellung auf zumindest einem der Rollenelemente aufliegt, wobei das erste Rollenelement bei anliegendem bzw. verriegeltem zweiten Gleisabschnitt fluchtend zur freien Oberfläche der Unterlage ausgerichtet ist oder über diese geringfügig vorsteht, oder wobei bei über der freien Oberfläche der Unterlage vorstehendem ersten Rollenelement der zweite Gleisabschnitt gewichtslos oder nahezu gewichtslos auf der Unterlage aufliegt, und daß die entlang des Verstellwegs (V) angeordneten Rollenelemente von der Halterung ausgehen, die über eine elastische Lagerung derart abgestützt ist, daß deren Steifigkeit mit zunehmender Last aufnehmender Fläche zunimmt und daß bei an dem ersten Schienenabschnitt anliegenden zweiten Schienenabschnitt die elastische Lagerung eine Keilform derart aufweist, daß deren Höhe schienenseitig geringer als im entferntliegenden Bereich ist. The problem is solved according to the invention in that the second rail section in the first rail section adjacent position on at least one of the roller elements rests, the first roller element with the adjacent or locked second track section is aligned with or slightly over the free surface of the underlay protrudes, or wherein the first above the free surface of the base Roller element of the second track section weightless or almost weightless on the base rests, and that the roller elements arranged along the adjustment path (V) of the Go out bracket that is supported via an elastic bearing so that its Stiffness increases with increasing load-bearing area and that at the first Rail section adjacent second rail section, the elastic storage Wedge shape in such a way that the height on the rail side is lower than in the distant one Area is.
Erfindungsgemäß erfolgt sowohl eine Verringerung der Gleitkräfte beim Öffnen des zweiten Gleisabschnitts als auch beim Auffahren des Fußes auf die folgenden Rollenelemente, da die entlang des Verstellwegs angeordneten Rollenelemente von einer gemeinsamen Halterung ausgehen, die ihrerseits über eine elastische Lagerung derart abgestützt ist, daß die Steifigkeit mit zunehmender lastaufnehmender Fläche zunimmt. Dabei ist bei an dem ersten Gleisabschnitt anliegendem zweiten Gleisabschnitt die elastische Lagerung derart keilförmig verformt, daß die Höhe schienenseitig geringer als im entferntliegenden Bereich ist. Hierdurch bedingt verlaufen die Rollen quasi entlang einer von dem zweiten Schienenabschnitt aus betrachtet ansteigenden Geraden mit der Folge, daß der rollenseitige Rand des Fußes des zweiten Gleisabschnitts wie Weichenzunge beim Anfahren des randseitigen Rollenelements diese nahezu tangential berührt, wodurch die unerwünschten Kraftspitzen unterbunden werden.According to the invention, both the sliding forces are reduced when the second is opened Track section as well as when moving the foot onto the following roller elements, because those arranged along the adjustment path Roll elements start from a common bracket, which in turn has a elastic support is supported such that the rigidity increases with increasing load Area increases. In this case, when there is contact with the first track section second track section deformed the elastic mounting so that the height is less on the rail side than in the distant area. Due to this run the rollers, as it were, viewed along one from the second rail section rising straight line with the result that the roller-side edge of the foot of the second Track section such as switch tongue when approaching the edge-side roller element touches almost tangentially, thereby preventing the undesired force peaks become.
Aufgrund der Federcharakteristik der elastischen Unterstützung, die aus Elastomermaterial besteht, erfolgt während des Verstellens des zweiten Schienenabschnitts ein langsames Anheben der Halterung, da während des Verstellens die Fläche, über die die Last abgetragen wird, mit der Folge zunimmt, daß sich die Steifigkeit der elastischen Lagerung erhöht. Infolgedessen ist in abliegender Stellung des zweiten Schienenabschnittes die zu Beginn vorhandene Keilform der elastischen Lagerung verlorengegangen.Due to the spring characteristics of the elastic support, which is made of elastomer material there is a slow movement during the adjustment of the second rail section Raise the bracket because during the adjustment the area over which the load is removed, with the result that the rigidity of the elastic increases Storage increased. As a result, the second rail section is in the remote position the existing wedge shape of the elastic bearing was lost.
Um das Elastomermaterial zu entlasten, sieht eine Weiterbildung der Erfindung vor, daß im schienenseitigen Randbereich der elastischen Lagerung eine mechanische, jedoch Federeigenschaften aufweisende Verstärkung vorhanden ist, die z.B. durch ein Tellerfedernpaket realisiert werden kann.In order to relieve the elastomer material, a further development of the invention provides that a mechanical, however, in the edge region of the elastic mounting on the rail side There is reinforcement with spring properties, e.g. through a disc spring package can be realized.
Alternativ können aufeinanderfolgende Rollen unterschiedlich gelagert bzw. voneinander abweichende Federeigenschaften derart aufweisen, daß die dem ersten Schienenabschnitt naheliegende Rolle bei Belastung stärker einsinkt als die entferntliegenden.Alternatively, successive roles can be stored differently or from each other have different spring properties such that the first rail section obvious role sinks more under load than the distant one.
Schließlich zeichnet sich die Erfindung dadurch aus, daß dann, wenn der zweite Schienenabschnitt bei in bezug auf den ersten Schienenabschnitt abliegender Stellung mit ihrem Fuß zwischen Rollenelemente festgelegt wie festgeklemmt ist, das oberhalb des Fußes verlaufende Rollenelement höhenverstellbar und/oder elastisch gelagert ist.Finally, the invention is characterized in that when the second Rail section in the position remote from the first rail section with her foot between roller elements fixed as is clamped that above of the foot-running roller element is adjustable in height and / or is mounted elastically.

In den nachstehenden Figuren, in denen grundsätzlich gleiche Elemente mit gleichen Bezugszeichen versehen sind, wird anhand eines Weichenbereichs die erfindungsgemäße Lehre erläutert. Hierdurch erfolgt jedoch keine Einschränkung, da die die Erfindung prägenden Merkmale in all denjenigen Gleisbereichen realisiert werden können, in denen Schienenabschnitte relativ zueinander verstellbar und gegebenenfalls miteinander verriegelt werden.In the following figures, in which basically the same elements with the same Reference numerals are provided, the turnout according to the invention Teaching explained. However, this does not impose a restriction since the invention defining features can be realized in all those track areas in which rail sections are adjustable relative to each other and possibly with each other be locked.
In den Fig. 1 und 2 ist rein prinzipiell ein Fuß (10) einer Weichenzunge dargestellt, die in Fig. 1 mit einer nichtdargestellten Backenschiene verriegelt bzw. an dieser angelegt und in Fig. 2 zu dieser abliegend angeordnet ist.1 and 2, a foot (10) of a switch tongue is shown purely in principle, the locked in Fig. 1 with a not shown stock rail or applied to this and in Fig. 2 is arranged remote from this.
Entlang ihres Verstellweges V sind Rollenelemente(12), (14) und (16) angeordnet, die von einer gemeinsamen Halterung (18) ausgehen, die ihrerseits über eine aus vorzugsweise Elastomer bestehenden elastischen Zwischenlage (20) auf einer Unterlage (22) abgestützt ist.Along their adjustment path V roller elements (12), (14) and (16) are arranged, which start from a common holder (18), which in turn preferably via one Elastomeric elastic intermediate layer (20) on a base (22) is supported.
Bei unbelasteten Rollenelementen (12), (14), (16) ragen diese in etwa 5 mm über die Oberfläche einer Abstützung wie Gleitstuhl (24) für die Weichenzunge vor. Wirkt jedoch die Weichenzunge auf die Rollenelemente (12), (14), (16), so werden diese in bezug auf die freie Oberfläche des Gleitstuhls (24) um in etwa 1 mm eingesenkt.When the roller elements (12), (14), (16) are unloaded, they protrude about 5 mm above the Surface of a support like sliding chair (24) for the switch tongue in front. acts however, the switch tongue on the roller elements (12), (14), (16), so these are in with respect to the free surface of the sliding chair (24) sunk by approximately 1 mm.
Um beim Verstellen der Weichenzunge (10) Kraftspitzen zu reduzieren, die durch Wechselwirken des vorderen Randes (26) der Weichenzunge mit in deren Verstellweg V angeordneten Rollenelementen (14) und (16) auftreten, ist erfindungsgemäß vorgesehen, daß der Fuß (10) auch bei verriegelter bzw. anliegender Weichenzunge auf einer Rolle (12) aufliegt, die bei anliegender bzw. verriegelter Weichenzunge heruntergedrückt und vorzugsweise mit der Oberfläche des Gleitstuhls fluchtet, wie durch die Fig. 1 angedeutet werden soll.To reduce force peaks when adjusting the switch tongue (10) Interaction of the front edge (26) of the switch tongue with in its adjustment path V arranged roller elements (14) and (16) occur, is provided according to the invention, that the foot (10) on a roller even when the switch tongue is locked or attached (12), which is pressed down when the switch tongue is attached or locked preferably flush with the surface of the sliding chair, as indicated by FIG. 1 shall be.
Durch das Einsenken des Rollenelementes (12) derart, daß ein Fluchten zum Gleitstuhl (24) erfolgt, wird die elastische Zwischenlage (20) dann, wenn eine Lastabtragung nur in ihrem vorderen Bereich, also über das Rollenelement (12) erfolgt, in einem Umfang zusammengedrückt, daß sich eine Keilform ergibt, die rein prinzipiell der Fig. 1 zu entnehmen ist. Hierdurch bedingt ist die im Verstellweg V der Weichenzunge nachfolgende Rolle (14) stärker als normal in bezug auf die freie Oberfläche des Gleitstuhls (24) eingesenkt, so daß der vordere Rand (26) der Weichenzunge das Rollenelement (14) quasi tangential anfährt, wodurch Kraftspitzen beim Verstellen weitgehend ausgeschlossen werden.By sinking the roller element (12) in such a way that an alignment to the sliding chair (24) takes place, the elastic intermediate layer (20) is only when a load transfer in its front area, that is to say via the roller element (12), to an extent compressed that there is a wedge shape, which in principle of Fig. 1 too can be seen. This causes the following in the adjustment path V of the switch tongue Roller (14) stronger than normal in relation to the free surface of the sliding chair (24) sunk so that the front edge (26) of the switch tongue the roller element (14) approaches almost tangentially, which largely eliminates force peaks when adjusting become.
Je weiter die Weichenzunge verstellt wird, um so größer wird die Fläche der Zwischenlage (20), über die die Last abgetragen wird, mit der Folge, daß die Steifigkeit zunimmt. Infolgedessen verliert sich die Keilform der Zwischenlage (20), wie die Fig. 2 belegt.The further the switch tongue is adjusted, the larger the area of the intermediate layer (20) over which the load is transferred, with the result that the rigidity increases. As a result, the wedge shape of the intermediate layer (20) is lost, as shown in FIG. 2.
Um die elastische Lagerung (20) in ihrem vorderen schienenseitigen Endbereich (28) zu entlasten, um also einen unerwünschten Verschleiß zu unterbinden, ist des weiteren vorgesehen, daß eine mechanische Verstärkung (30) eingelassen ist, die aus einem Tellerfedernpaket bestehen kann.To the elastic mounting (20) in its front rail-side end region (28) relieve pressure, in order to prevent undesired wear, is also provided, that a mechanical reinforcement (30) is embedded, which consists of a plate spring package can exist.
In abliegender Stellung ist der Schienenfuß (10) zwischen dem unterseitig angeordneten Rollenelement (16) und einem oberen Rollenelement (32) festgelegt bzw. festgeklemmt, welches sich auf der Oberseite (34) des Fußes (10) abstützt.In the remote position, the rail foot (10) is located between the bottom Roller element (16) and an upper roller element (32) fixed or clamped, which is supported on the top (34) of the foot (10).
Um das Festklemmen im gewünschten Umfang sicherzustellen, ist das Rollenelement (32) einerseits über seine Halterung (36) höhenverstellbar und andererseits elastisch gelagert. Hierzu weist die Halterung (36) einen elastischen Abschnitt (38) auf.The roller element is to ensure that it is clamped to the desired extent (32) on the one hand height-adjustable via its holder (36) and on the other hand elastic stored. For this purpose, the holder (36) has an elastic section (38).
In den Fig. 3 und 4 ist eine Weichenzunge (40) mit ihrem Fuß (10) sowie eine zugeordnete Backenschiene (42) dargestellt, die von einer Platte (44) ausgeht und deren Fuß (46) einerseits von einer Klemmplatte (48) und andererseits von einem sich entlang der Oberseite des Schienenfußes (46) erstreckenden Abschnitt (50) einer Halterung (52) festgelegt ist, die ihrerseits mit der Platte (44) verschweißt sein kann.3 and 4 is a switch tongue (40) with its foot (10) and an associated Shown rail (42), which starts from a plate (44) and the foot (46) on the one hand from a clamping plate (48) and on the other hand from one along the Top of the rail foot (46) extending portion (50) of a bracket (52) is fixed, which in turn can be welded to the plate (44).
Von der Halterung (52) gehen im Ausführungsbeispiel zwei Rollenelemente (54) und
(56) aus, auf die sich der Fuß (10) der Weichenzunge (40) sowohl in anliegender als
auch in abliegender Stellung abstützt. Dabei fluchtet zumindest das erste Rollenelement
(54) mit der freien Oberfläche eines nicht dargestellten Gleitstuhls bzw. ragt über
dessen Oberfläche geringfügig vor, sofern eine Belastung durch die Weichenzunge (40)
erfolgt. Hierdurch ergeben sich die Vorteile, die im Zusammenhang mit dem Ausführungsbeispiel
der Fig. 1 und 2 erläutert worden sind.In the exemplary embodiment, two roller elements (54) and
(56) on which the foot (10) of the switch tongue (40) both in adjacent and
also supports in the remote position. At least the first roller element is aligned
(54) with the free surface of a sliding chair, not shown, or protrudes
the surface of which slightly before, if there is a load through the switch tongue (40)
he follows. This results in the advantages associated with the
Zumindest das Rollenelement (54), das über eine Achse (58) starr gelagert ist, weist einen Schwingmetallaufbau auf, d. h., zwischen einer äußeren metallischen Hülse (62) und einer achsseitigen Hülse (64) ist eine aus elastischem Material bestehende Zwischenlage (66) angeordnet wie einvulkanisiert. Hierdurch erfährt das Rollenelement (54) eine Federeigenschaft derart, daß beim Verstellen der Weichenzunge (40) ein Entlanggleiten auf diesen erfolgt, ohne daß ein zu hohen Reibungsverlusten führendes flächiges Entlanggleiten des Fußes (10) auf dem Gleitstuhl erfolgt. Gleichzeitig wird erreicht, daß beim Verstellen der Weichenzunge das folgende Rollenelement (56), das ebenfalls über eine Achse (60) starr gelagert ist, jedoch geringere Federeigenschaften aufweist, quasi tangential angefahren wird.At least the roller element (54), which is rigidly mounted on an axis (58), has a vibrating metal structure, d. that is, between an outer metallic sleeve (62) and an axle-side sleeve (64) is an intermediate layer made of elastic material (66) arranged as vulcanized. This causes the roller element (54) to experience a spring characteristic such that sliding along the switch tongue (40) this takes place without a flat surface leading to high friction losses Glide along the foot (10) on the sliding chair. At the same time it is achieved that when adjusting the switch tongue the following roller element (56), which is also about an axis (60) is rigidly mounted, but has lower spring properties, so to speak is approached tangentially.
