Definitions
- the invention relates to a track switch, in particular to a track switch with a large radius, in which the tongue rails can be adjusted in two end positions by means of an adjusting device, in each of which a tongue tip rests on the associated stock rail, with a position securing device for securing the position on the tongue rails
- the same is arranged, which has at least one multi-armed lever which engages on the tongue rails and can be pivoted about a fixed axis of rotation and is loaded by a force accumulator and which can be actuated by the tongue rails adjustable by the adjusting device, the line of action of the force of the force accumulator, in particular formed by a compression spring, in the two end positions of the lever on different sides of the pivot axis of the same.
- the rails are bent by two trolleys, one of which is moved along a track parallel to the main track and the other along a track parallel to the secondary track. With these trolleys, the curved, continuous rails can be clamped in their respective bending position on each sleeper.
- Such an arrangement is extremely complex and is also not usable for track switches in which the tongue rails are respectively applied to or lifted from the associated stock rail.
- the invention aims at ensuring the correct position of the switch tongues in the intermediate areas of the switch or in the central area of the switch and thus the required minimum distance between the remote switch tongue and the stock rail.
- the invention essentially consists in that the position securing device is arranged in an intermediate region of the length of the tongue rails, in particular in the central region thereof, that the end position of the lever, which determines the distance of the remote tongue rail from the cheek rail, by means of an interaction with the lever, Fixed, separate from the stock rail, optionally adjustable, stop is determined, and that the position securing device has two two-armed angle levers, one arm of which is articulated to a tongue rail and the other arm of which is supported against the energy accumulator.
- the levers are held in the respective position of the position securing device by the energy accumulator, whereby the tongue rails are held in their correct position by the articulation of the tongue rails.
- the correct position is determined by the stop and it is ensured even with great elasticity of the switch tongues by the selected position of the position securing device that the switch tongues lie in the correct position in the intermediate areas and in the central area, so that the maintenance of the free passage between the remote ones Tongue rail and the associated stock rail is guaranteed.
- the angle levers are adjusted by the tongue rails overcoming the force of the energy accumulator via a tipping point, whereupon the energy accumulator acts in the other direction and presses the levers into the other end position, in which the tongue rails are again in the correct position.
- the correct position of the tongue rails is determined by the respective end positions of the lever in that the end position of the lever which determines the distance of the remote tongue rail from the stock rail is determined by a fixed stop which interacts with the lever and which is separate and optionally adjustable from the stock rail . Due to the possible adjustability of the The correct position of the tongue rails in the intermediate areas or in the middle area can be set.
- Each angle lever of the position securing device having two two-arm angle levers can be supported against a separate energy store, which in turn is supported against a stationary abutment.
- Such a design of angle levers is known in principle from DE-AS 15 30 341.
- the angle levers are not actuated by the tongue rails, which can be adjusted by a separate adjusting device, but these angle levers themselves form the arbitrarily actuable adjusting device for the switch, which acts on the tongue tips of the tongue rails.
- the tip of the tongue is adjusted by electromagnets that engage these angle levers.
- the arms of the two angle levers can also be supported against a single common energy store.
- both angle levers swivel in different directions.
- the support points of the energy accumulator thus move in opposite directions.
- the angles which include the direction of force of the energy accumulator with the arms of the two angle levers acting on the energy accumulator are increased in the end positions thereof, and the two angle levers are therefore held in their end positions with greater certainty.
- This increased safety is essential if the tongue rails are to be held in their position in an intermediate area exclusively by the angle levers.
- the angle levers must be arranged between the tracks, since they interact with one another via the spring-loaded mechanism. If, on the other hand, each angle lever is supported on a stationary abutment by a separate energy store, the angle levers can also be arranged on both sides of the same outside the track.
- the switch can also be changed by a clamp fastener located in the tip area of the tongue rails and the correct position of the tongue rail is now set in one or more intermediate areas, the position securing device being automatically changed by the tongue rails itself, without the need for a separate actuating device.
- Fig. 1 shows a plan view of the track switch
- Fig. 2 and 3 show different designs of the position securing device on a larger scale in plan view.
- Fig. 1 the entire switch area is shown in plan view. 1 and 2 are the two stock rails, 3 and 4 are the two tongue rails.
- tongue area A depending on the position of the switch, either the tongue tip of the tongue rail 3 is in contact with the stock rail 1 or the tongue tip of the tongue rail 4 is in contact with the stock rail 2.
- the switch is adjusted in the usual way by an adjusting device which forms a clamp closure and is not shown in the drawing and which acts on the tongue rails 3 and 4 in the tongue area A. Due to the elasticity of the switch rails, the position of the switch rails in the intermediate areas of the switch is not secured for switches with a large radius.
- a position securing device B which determines the position of the tongue rails in this area, is therefore arranged in an intermediate region or in the middle region of the position of the switch or the tongue rails.
- This position securing device B is shown in Fig. 2 on a larger scale.
- the stock rails are again labeled 1 and 2 and the tongue rails 3 and 4.
- a plate 5 is fixed to the sleepers.
- This plate carries pivot axes 6, on which angle levers 7 and 8 are pivotally attached.
- the ends of the arms 9 and 10 are articulated on the tongue rails via length-adjustable rods 11.
- the arms 12 and 13 are supported against each other by an energy accumulator 14 formed by a compression spring.
- the tongue rail 4 lies away from the stock rail 2, the passage between the stock rail 2 and the tongue rail 4 being designated by 15.
- the tongue tip of the tongue rail 3 lies against the stock rail 1.
- the end position of the angle lever 8, which determines the largest passage 15 between the stock rail 2 and the tongue rail 4 is determined by a stop 16.
- the end position of the angle lever 7 is determined in an analogous manner by a stop 17.
- the axes 6 and the stops 16 and 17 are fixed in place on the plate 5, which in turn is attached to the sleepers, not shown.
- the narrowest passage 15 between the stock rail 2 and the tongue rail 4 is limited by the angle levers 7 and 8 in cooperation with the energy accumulator 14 and on the guarantee this narrowest passage is important so that the wheel flanges of the edges can pass over the stock rails 1 and 2 without hindrance.
- the ends or articulation points 18 and 19 of the arms 12 and 13 move in opposite directions.
- the angle ⁇ which includes the line of action 20 of the force of the energy accumulator 14 with the arms 12 and 13, is substantially greater than if the energy accumulator 14 were supported in a stationary manner, and it becomes the end position of the angle levers 7 and 8 which define the passage 15 determined between stock rail and tongue rail, adhered to with the greatest possible certainty.
- 21 is a telescopic tube which prevents the compression spring 14 forming the energy accumulator from buckling.
- the position of the tongue rails 3 and 4 relative to the stock rails 1 and 2 is again determined by angle levers 7 and 8.
- the arms 9 and 10 engage at 23 on the tongue rails 3 and 4 via adjustable rods 22.
- Force accumulators 24 engage arms 12 and 13 again. However, these energy stores 24 are supported here against abutments 27 fixed on plates 25 which are fastened to the sleepers 26.
- Both tongue rails can be connected to one another by a rod 30, which may be adjustable in length. If one of the tongue rails 3 or 4 abuts a stock rail 1 or 2 in this area, the stops 29 can be replaced by the connecting rod 30.
- the plates 25 with the angle levers 7 and 8 are arranged outside the track on both sides of the same. These plates 25 with the angle levers 7 and 8 can also be arranged between the tracks.

Description
Die Erfindung bezieht sich auf eine Gleisweiche, insbesondere auf eine Gleisweiche mit großem Radius, bei welcher die Zungenschienen mittels einer Stellvorrichtung in zwei Endstellungen verstellbar sind, in welchen jeweils eine Zungenspitze an der zugehörigen Backenschiene anliegt, wobei an den Zungenschienen eine Lagesicherungsvorrichtung zur Sicherung der Lage derselben angeordnet ist, welche wenigstens einen an den Zungenschienen angreifenden, um eine ortsfeste Drehachse schwenkbaren, durch einen Kraftspeicher belasteten mehrarmigen Hebel aufweist, der durch die durch die Stellvorrichtung verstellbaren Zungenschienen betätigbar ist, wobei die Wirkungslinie der Kraft des insbesondere von einer Druckfeder gebildeten Kraftspeichers in den beiden Endlagen des Hebels zu verschiedenen Seiten der Schwenkachse desselben liegt.The invention relates to a track switch, in particular to a track switch with a large radius, in which the tongue rails can be adjusted in two end positions by means of an adjusting device, in each of which a tongue tip rests on the associated stock rail, with a position securing device for securing the position on the tongue rails The same is arranged, which has at least one multi-armed lever which engages on the tongue rails and can be pivoted about a fixed axis of rotation and is loaded by a force accumulator and which can be actuated by the tongue rails adjustable by the adjusting device, the line of action of the force of the force accumulator, in particular formed by a compression spring, in the two end positions of the lever on different sides of the pivot axis of the same.
Insbesondere bei Gleisweichen mit großem Radius ist infolge der Länge und Elastizität der Weichenzungen die richtige Lage der Zungenschienen im Mittelbereich bzw. in den Zwischenbereichen der Weiche nicht gewährleistet. Es besteht daher auch die Gefahr, daß in diesen Bereichen der lichte Abstand zwischen der abliegenden Zungenschiene und der Backenschiene zu gering für den freien Durchgang der Spurkränze der Räder ist. Dies hat eine Beschädigung der Spurkränze zur Folge, die weiterhin zu Entgleisungen führen kann. Aus der DE-AS 27 28 413 ist eine Weiche bekannt geworden, bei welcher durchlaufende Schienen im Weichenbereich in die Lage des Hauptgeleises oder in die Lage des Nebengeleises gebogen werden. Die Verbiegung der Schienen erfolgt durch zwei Stellwagen, von welchen einer entlang einer zum Hauptgeleise parallelen Bahn und der andere entlang einer zum Nebengeleise parallelen Bahn verfahren wird. Durch diese Stellwagen können auch die gebogenen durchlaufenden Schienen in ihrer entsprechenden Biegelage an jeder Schwelle verklammert werden. Eine solche Anordnung ist aber äußerst aufwendig und ist auch nicht für Gleisweichen verwendbar, bei welchen die Zungenschienen jeweils an die zugehörige Backenschiene angelegt oder von dieser abgehoben wird.In the case of track turnouts with a large radius in particular, the correct position of the tongue rails in the central area or in the intermediate areas of the turnout cannot be guaranteed due to the length and elasticity of the turnout tongues. There is therefore also the risk that in these areas the clear distance between the remote tongue rail and the stock rail is too small for the free passage of the wheel flanges of the wheels. This results in damage to the wheel flanges, which can still lead to derailment. A switch has become known from DE-AS 27 28 413, in which continuous rails in the switch area are bent into the position of the main track or into the position of the secondary track. The rails are bent by two trolleys, one of which is moved along a track parallel to the main track and the other along a track parallel to the secondary track. With these trolleys, the curved, continuous rails can be clamped in their respective bending position on each sleeper. However, such an arrangement is extremely complex and is also not usable for track switches in which the tongue rails are respectively applied to or lifted from the associated stock rail.
Eine Ausbildung der eingangs genannten Art ist beispielsweise der US-A 2 906 477 entnehmbar. Bei dieser bekannten Ausbildung wurde darauf abgezielt, die Anlagestellung der Zungenschienenspitze in einer Weise zu sichern, daß diese frei von Federkräften gehalten wird, wobei dies durch andere Mittel als durch eine Feder erreicht werden soll. Zu diesem Zweck schlägt die US-A 2 906 477 vor, eine sogenannte Totpunktslagenverriegelung zu schaffen. Es soll somit eine Schwenkstellung des mehrarmigen Hebels eingenommen werden, bei welcher der Hebelarm, welcher über eine Stange am Zungenschienenende angreift, in gestreckter bzw. fluchtender Lage mit der am Zungenschienenende angreifenden Stange liegt. Bei einer derartigen Ausbildung bleiben eine Reihe von Problemen unberührt und auch nicht gelöst. Insbesondere ist nicht ohne weiteres klar und ersichtlich, wie ohne zusätzliche Maßnahmen ein Umlegen der Zungenschienen bzw. eine Verstellung in die andere Lage möglich ist. Die gestreckte Lage bzw. Totpunktverriegelung führt nämlich dazu, daß ein derartiges Umlegen der Zungenschienenenden blockiert wird. Eine Verstellung scheint somit offensichtlich nur durch eine komplizierte Nachlaufsteuerung der Verschiebebewegung möglich, bei welcher der mehrarmige Hebel zunächst aus seiner gestreckten Lage herausgezogen wird.An embodiment of the type mentioned in the introduction can be found, for example, in US Pat. No. 2,906,477. In this known design, the aim was to secure the contact position of the tongue rail tip in such a way that it is kept free of spring forces, which is to be achieved by means other than a spring. For this purpose, US-A 2 906 477 proposes to create a so-called dead center lock. A pivot position of the multi-armed lever is thus to be assumed, in which the lever arm, which engages via a rod at the end of the tongue rail, lies in an extended or aligned position with the rod engaging at the end of the tongue rail. With such training, a number of problems remain unaffected and not solved. In particular, it is not immediately clear and obvious how it is possible to flip the tongue rails or move them to the other position without additional measures. The extended position or dead center lock leads to the fact that such a flipping of the tongue rail ends is blocked. An adjustment therefore seems to be possible only through a complicated follow-up control of the displacement movement, in which the multi-arm lever is first pulled out of its extended position.
Die Erfindung zielt darauf ab, bei Weichen der eingangs genannten Art die richtige Stellung der Weichenzungen in den Zwischenbereichen der Weiche bzw. im Mittelbereich derselben und damit den erforderlichen Mindestabstand zwischen der abliegenden Weichenzunge und der Backenschiene zu gewährleisten. Zur Erreichung dieser Aufgabe besteht die Erfindung im wesentlichen darin, daß die Lagesicherungsvorrichtung in einem Zwischenbereich der Länge der Zungenschienen, insbesondere im Mittelbereich derselben angeordnet ist, daß die den Abstand der abliegenden Zungenschiene von der Backenschiene bestimmende Endlage des Hebels durch einen mit dem Hebel zusammenwirkenden, ortsfesten, von der Backenschiene gesonderten, gegebenenfalls einstellbaren, Anschlag bestimmt ist, und daß die Lagesicherungsvorrichtung zwei zweiarmige Winkelhebel aufweist, deren einer Arm an je eine Zungenschiene angelenkt ist und deren anderer Arm gegen den Kraftspeicher abgestützt ist. Durch den Kraftspeicher werden die Hebel in der jeweiligen Stellung der Lagesicherungsvorrichtung gehalten, wobei durch die Anlenkung der Zungenschienen an den Hebeln diese in ihrer korrekten Lage gehalten werden. Durch den Anschlag ist diese korrekte Lage bestimmt und es wird auch bei großer Elastizität der Weichenzungen durch die gewählte Position der Lagesicherungsvorrichtung gewährleistet, daß die Weichenzungen in den Zwischenbereichen und im Mittelbereich in der richtigen Lage liegen, so daß die Aufrechterhaltung des freien Durchganges zwischen der abliegenden Zungenschiene und der zugehörigen Backenschiene gewährleistet ist. Die Winkelhebel werden durch die Zungenschienen unter Überwindung der Kraft des Kraftspeichers über einen Kippunkt verstellt, worauf dann der Kraftspeicher in die andere Richtung wirkt und die Hebel in die andere Endlage drückt, in welcher wieder die Zungenschienen in der korrekten Lage gehatten werden.The invention aims at ensuring the correct position of the switch tongues in the intermediate areas of the switch or in the central area of the switch and thus the required minimum distance between the remote switch tongue and the stock rail. To achieve this object, the invention essentially consists in that the position securing device is arranged in an intermediate region of the length of the tongue rails, in particular in the central region thereof, that the end position of the lever, which determines the distance of the remote tongue rail from the cheek rail, by means of an interaction with the lever, Fixed, separate from the stock rail, optionally adjustable, stop is determined, and that the position securing device has two two-armed angle levers, one arm of which is articulated to a tongue rail and the other arm of which is supported against the energy accumulator. The levers are held in the respective position of the position securing device by the energy accumulator, whereby the tongue rails are held in their correct position by the articulation of the tongue rails. The correct position is determined by the stop and it is ensured even with great elasticity of the switch tongues by the selected position of the position securing device that the switch tongues lie in the correct position in the intermediate areas and in the central area, so that the maintenance of the free passage between the remote ones Tongue rail and the associated stock rail is guaranteed. The angle levers are adjusted by the tongue rails overcoming the force of the energy accumulator via a tipping point, whereupon the energy accumulator acts in the other direction and presses the levers into the other end position, in which the tongue rails are again in the correct position.
Dadurch, daß die den Abstand der abliegenden Zungenschiene von der Backenschiene bestimmende Endlage des Hebels durch einen mit dem Hebel zusammenwirkenden, ortsfesten, von der Backenschiene gesonderten, gegebenenfalls einstellbaren, Anschlag bestimmt ist, wird die richtige Lage der Zungenschienen durch die jeweiligen Endlagen des Hebels bestimmt. Durch die gegebenenfalls mögliche Verstellbarkeit der Anschläge kann die richtige Lage der Zungenschienen in den Zwischenbereichen bzw. im Mittelbereich eingestellt werden.The correct position of the tongue rails is determined by the respective end positions of the lever in that the end position of the lever which determines the distance of the remote tongue rail from the stock rail is determined by a fixed stop which interacts with the lever and which is separate and optionally adjustable from the stock rail . Due to the possible adjustability of the The correct position of the tongue rails in the intermediate areas or in the middle area can be set.
Es kann jeder Winkelhebel der zwei zweiarmige Winkelhebel aufweisenden Lagesicherungsvorrichtung gegen einen gesonderten Kraftspeicher abgestützt sein, welcher seinerseits wieder gegen ein ortsfestes Widerlager abgestützt ist. Eine solche Ausbildung von Winkelhebeln ist prinzipiell aus der DE-AS 15 30 341 bekannt. Hiebei werden die Winkelhebel jedoch nicht durch die Zungenschienen betätigt, welche durch eine gesonderte Stellvorrichtung verstellbar sind, sondern diese Winkelhebel bilden selbst die willkürlich betätigbare Verstellvorrichtung für die Weiche, welche an den Zungenspitzen der Zungenschienen angreift. Die Verstellung der Zungenspitzen erfolgt hiebei durch an diesen Winkelhebeln angreifende Elektromagnete. Diese Winkelhebel können daher nicht die Lage der Zungenschienen in einem Zwischenbereich oder Mittelbereich der Weiche sichern.Each angle lever of the position securing device having two two-arm angle levers can be supported against a separate energy store, which in turn is supported against a stationary abutment. Such a design of angle levers is known in principle from DE-AS 15 30 341. However, the angle levers are not actuated by the tongue rails, which can be adjusted by a separate adjusting device, but these angle levers themselves form the arbitrarily actuable adjusting device for the switch, which acts on the tongue tips of the tongue rails. The tip of the tongue is adjusted by electromagnets that engage these angle levers. These angle levers can therefore not secure the position of the tongue rails in an intermediate or middle area of the switch.
Die Arme der beiden Winkelhebel können auch gegen einen einzigen gemeinsamen Kraftspeicher abgestützt sein. Bei der Umstellung der Weiche schwenken beide Winkelhebel in verschiedenem Drehsinn. Die Abstützpunkte des Kraftspeichers verschieben sich somit gegenläufig. Dadurch werden die Winkel, welche die Kraftrichtung des Kraftspeichers mit den am Kraftspeicher angreifenden Armen der beiden Winkelhebel in den Endlagen derselben einschließen, vergrößert und die beiden Winkelhebel werden daher mit größerer Sicherheit in ihren Endlagen gehalten. Diese vergrößerte Sicherheit ist dann von wesentlicher Bedeutung, wenn die Zungenschienen in einem Zwischenbereich aüsschließlich durch die Winkelhebel in ihrer Lage gehalten werden sollen. Bei einer solchen Ausbildung müssen die Winkelhebel zwischen den Geleisen angeordnet sein, da sie ja über den Federspeicher miteinander zusammenwirken. Wenn jeder Winkelhebel dagegen durch einen gesonderten Kraftspeicher an einem ortsfesten Widerlager abgestützt ist, können die Winkelhebel auch außerhalb des Geleises zu beiden Seiten desselben angeordnet sein.The arms of the two angle levers can also be supported against a single common energy store. When switching the switch, both angle levers swivel in different directions. The support points of the energy accumulator thus move in opposite directions. As a result, the angles which include the direction of force of the energy accumulator with the arms of the two angle levers acting on the energy accumulator are increased in the end positions thereof, and the two angle levers are therefore held in their end positions with greater certainty. This increased safety is essential if the tongue rails are to be held in their position in an intermediate area exclusively by the angle levers. With such a design, the angle levers must be arranged between the tracks, since they interact with one another via the spring-loaded mechanism. If, on the other hand, each angle lever is supported on a stationary abutment by a separate energy store, the angle levers can also be arranged on both sides of the same outside the track.
Die Umstellung der Weiche kann weiterhin durch einen im Spitzenbereich der Zungenschienen angeordneten Klammerverschluß erfolgen und in einem oder mehreren Zwischenbereichen wird nun die richtige Lage der Zungenschiene eingestellt, wobei die Umstellung der Lagesicherungsvorrichtung durch die Zungenschienen selbst automatisch erfolgt, ohne daß es einer eigenen Betätigungsvorrichtung bedarf.The switch can also be changed by a clamp fastener located in the tip area of the tongue rails and the correct position of the tongue rail is now set in one or more intermediate areas, the position securing device being automatically changed by the tongue rails itself, without the need for a separate actuating device.
In den Zeichnungen ist die Erfindung an Hand von Ausführungsbeispielen schematisch erläutert.In the drawings, the invention is explained schematically using exemplary embodiments.
Fig. 1 zeigt eine Draufsicht auf die Gleisweiche, und Fig. 2 und 3 zeigen verschiedene Ausbildungen der Lagesicherungsvorrichtung in größerem Maßstab in Draufsicht.Fig. 1 shows a plan view of the track switch, and Fig. 2 and 3 show different designs of the position securing device on a larger scale in plan view.
In Fig. 1 ist der gesamte Weichenbereich in Draufsicht dargestellt. 1 und 2 sind die beiden Backenschienen, 3 und 4 sind die beiden Zungenschienen. Im Zungenbereich A liegt je nach der Stellung der Weiche entweder die Zungenspitze der Zungenschiene 3 an der Backenschiene 1 an oder es liegt die Zungenspitze der Zungenschiene 4 an der Backenschiene 2 an. Die Verstellung der Weiche erfolgt in üblicher Weise von einer, einen Klammerverschluß bildenden, in der Zeichnung nicht dargestellten Stellvorrichtung, welche im Zungenbereich A an den Zungenschienen 3 und 4 angreift. Infolge der Elastizität der Zungenschienen ist bei Weichen mit großem Radius die Lage der Zungenschienen in den Zwischenbereichen der Weiche nicht gesichert. Es ist daher in einem Zwischenbereich bzw. im Mittelbereich der Lage der Weiche bzw. der Zungenschienen eine Lagesicherungsvorrichtung B angeordnet, welche die Stellung der Zungenschienen in diesem Bereich bestimmt.In Fig. 1 the entire switch area is shown in plan view. 1 and 2 are the two stock rails, 3 and 4 are the two tongue rails. In the tongue area A, depending on the position of the switch, either the tongue tip of the

Diese Platte trägt Schwenkachsen 6, an welchen Winkelhebel 7 und 8 schwenkbar festgelegt sind. Die Enden der Arme 9 und 10 sind über längeneinstellbare Stangen 11 an den Zungenschienen angelenkt. Die Arme 12 und 13 sind durch einen von einer Druckfeder gebildeten Kraftspeicher 14 gegeneinander abgestützt. In der Darstellung der Fig. 2 liegt die Zungenschiene 4 von der Backenschiene 2 ab, wobei der Durchgang zwischen Backenschiene 2 und Zungenschiene 4 mit 15 bezeichnet ist. Die Zungenspitze der Zungenschiene 3 liegt an der Backenschiene 1 an. Die Endlage des Winkelhebels 8, welche den größten Durchgang 15 zwischen Backenschiene 2 und Zungenschiene 4 bestimmt, ist durch einen Anschlag 16 bestimmt. Die Endlage des Winkelhebels 7 ist in analoger Weise durch einen Anschlag 17 bestimmt. Die Achsen 6 und die Anschläge 16 und 17 sind ortsfest an der Platte 5 festgelegt, welche ihrerseits an den nicht dargestellten Schwellen befestigt ist.This plate carries
Bei einer Verstellung der Weiche werden durch die Stangen 11 die Arme 9 und 10 der Winkelhebel mitgenommen. Die Winkelhebel 7 und 8 werden verschwenkt und die Zungenschiene 3 von der Backenschiene 1 abgehoben, wobei die Zungenschiene 4 an die Backenschiene 2 angelegt wird. Es ergibt sich hiebei eine spiegelbildlich gleiche Stellung der in Fig. 2 dargestellten Anordnung. Der Kraftspeicher 14 steht nun in der anderen Richtung schräg und beim Übergang in diese neue Stellung überschreitet der Kraftspeicher 14 die Kippstellung, in welcher er in einer Linie mit den Armen 12 und 13 liegt und daher auf das kleinste Maß zusammengedrückt ist. In dieser umgestellten Lage liegt dann der Arm 12 an dem Anschlag 17 an, und der Arm 13 ist vom Anschlag 16 abgehoben.When the switch is adjusted, the
Da durch den Kraftspeicher 14 die Arme 12 und 13 stets an einen der Anschläge 16 und 17 angedrückt sind (bei der in der Zeichnung dargestellten Stellung ist der Arm 13 an den Anschlag 16 angedrückt), wird durch die Winkelhebel 7 und 8 in Zusammenwirken mit dem Kraftspeicher 14 auch der engste Durchgang 15 zwischen Backenschiene 2 und Zungenschiene 4 begrenzt und auf die Gewährleistung dieses engsten Durchganges kommt es an, damit die Spurkränze der Ränder unbehindert die Backenschienen 1 und 2 überfahren können.Since the
Beim Umstellen der Weiche bewegen sich somit die Enden bzw. Anlenkstellen 18 und 19 der Arme 12 und 13 gegenläufig. Dadurch wird der Winkel ∞, welchen die Wirkungslinie 20 der Kraft des Kraftspeichers 14 mit den Armen 12 und 13 einschließt, wesentlich größer, als wenn der Kraftspeicher 14 ortsfest abgestützt wäre, und es wird die Endlage der Winkelhebel 7 und 8, welche den Durchgang 15 zwischen Backenschiene und Zungenschiene bestimmt, mit größter Sicherheit eingehalten. 21 ist ein Teleskoprohr, welches ein Ausknicken der den Kraftspeicher bildenden Druckfeder 14 verhindert.When moving the switch, the ends or
Bei der Anordnung nach Fig. 3 ist wieder die Stellung der Zungenschienen 3 und 4 relativ zu den Backenschienen 1 und 2 durch Winkelhebel 7 und 8 bestimmt. Die Arme 9 und 10 greifen über einstellbare Stangen 22 bei 23 an den Zungenschienen 3 und 4 an. An den Armen 12 und 13 greifen wieder Kraftspeicher 24 an. Diese Kraftspeicher 24 sind aber hier gegen ortsfest an Platten 25, welche an den Schwellen 26 befestigt sind, festgelegte Widerlager 27 abgestützt.In the arrangement according to FIG. 3, the position of the tongue rails 3 and 4 relative to the stock rails 1 and 2 is again determined by
Beide Zungenschienen können durch eine, gegebenenfalls längeneinstellbare Stange 30 miteinander verbunden sein. Wenn in diesem Bereich jeweils eine der Zungenschienen 3 oder 4 an einer Backenschiene 1 oder 2 anliegt, können die Anschläge 29 durch die Verbindungsstange 30 ersetzt werden.Both tongue rails can be connected to one another by a
