Einrichtung zum Verstellen und zum elastischen Verriegeln von beweglichen WeichenteilenDevice for adjusting and elastically locking movable switch parts
Die Erfindung bezieht sich auf eine Einrichtung zum Verstellen und zum elastischen Verriegeln der Endlage von beweglichen Weichenteilen, insbesondere von Weichenzungen von Rillenschie- nenweichen, mit einer axial verschieblichen Stange und einem die Stange umgebenden Rohr, in welchem eine die Stange umgreifende Feder gegen Anschläge verspannt ist und radial auswärts ver- schiebbare Verriegelungsglieder angeordnet sind, wobei die Stange in axialem Abstand Steueranschläge für eine radial innere Lage der Verriegelungsglieder und das Rohr Anschläge für die äußere Lage der Verriegelungsglieder aufweist.The invention relates to a device for adjusting and for elastically locking the end position of movable switch parts, in particular switch tongues of grooved rail switches, with an axially displaceable rod and a tube surrounding the rod, in which a spring encompassing the rod is clamped against stops and locking members which can be moved radially outward are arranged, the rod having control stops at an axial distance for a radially inner position of the locking members and the tube having stops for the outer position of the locking members.
Zur Verriegelung von beweglichen Weichenteilen ist neben dem sogenannten Klammerspitzenverschluß in der EP 603 156 AI bereits eine Ausbildung vorgeschlagen worden, bei welcher außeraxiale Belastungen des Verschlusses vermieden werden und eine vollkommen geschlossene Bauweise realisiert werden kann. Bei dieser bekannten Verriegelung, welche bei entsprechender Anordnung von Druckfedern auch als Umstellhilfe zum Einsatz gelangen kann, ist eine Stange in einem axial verschieblichen Rohr angeordnet, welche selbst wiederum in einem ortsfesten Rohr angeordnet war. Im axial verschieblichen Rohr waren Verriegelungsglieder in radialer Richtung verschiebbar geführt, und es waren jeweils Ausnehmungen im ortsfesten Rohr und in der Stange vorgesehen, mit welchen die Verriegelungsglieder bei der Verschiebung bzw. in der Endlage zusammenwirken. Bei der Verwendung einer derartigen Anordnung als Umstellhilfe zum Unterstützen der Verschiebe- bewegung wurden zwei Druckfedern eingesetzt, wodurch sich insgesamt ein relativ hoher konstruktiver Aufwand ergab. Ausführungsformen einer Umstellhilfe sind auch aus der AT-PS 379 624 bereits bekannt geworden, wobei hier eine Federwippe zum Einsatz gelangte, bei der ein Winkelhebel im Kreuzungspunkt der Arme gelagert ist, wobei ein Kraftspeicher mittels einer Druckfeder gegen die Arme der beiden Winkelhebel abgestützt ist. Zwei Federwippen waren hier über eine Koppelstange mit den beiden Zungenschienen verbunden. Aus der österreichischen Anmeldung A 2137/97 ist eine Umstellhilfe für ein elastisches Verriegeln von beweglichen Weichenteilen bekanntgeworden, bei welcher Verriegelungsglieder in axialem Abstand voneinander in zwischen einem Rohr und einer Stange angeordneten Käfigen gelagert sind, wobei zwischen diesen Käfigen eine in axialer Richtung wirkende Druckfeder angeordnet ist. Die Stange ist über Koppelstangen mit den Zungenschienen verbunden, wobei am Umfang der Stange Steuernuten angeordnet sind, welche die Verriegelungsglieder in ihre verschiedenen Positionen bewegen, sodaß die Druckfeder während des Umstellvorganges gespannt wird und in der Position der Anlage der Zunge an die Rillenschienen eine Anpreßkraft auf die Zunge ausübt. Die Kugelkäfige sind hiebei in beschränktem Ausmaß axial beweglich, sodaß ein Einsatz bei unterschiedlichem Zungenaufschlag bzw. unterschiedlicher Querbewegung der Zunge möglich ist. Die Druckfeder übt bei diesen bekannten Einrichtungen je nach Spannlänge unterschiedliche Kräfte auf die Zunge aus.To lock movable switch parts, in addition to the so-called clip tip lock, EP 603 156 AI has already proposed a design in which off-axis loads on the lock are avoided and a completely closed design can be implemented. In this known locking device, which can also be used as a changeover aid with a corresponding arrangement of compression springs, a rod is arranged in an axially displaceable tube, which in turn was arranged in a stationary tube. In the axially displaceable tube, locking members were guided so as to be displaceable in the radial direction, and recesses were provided in the stationary tube and in the rod, with which the locking members interact during the displacement or in the end position. When using such an arrangement as a changeover aid to support the displacement movement, two compression springs were used, which overall resulted in a relatively high design effort. Embodiments of a changeover aid have also become known from AT-PS 379 624, a spring rocker being used here in which an angle lever is mounted at the crossing point of the arms, an energy store being supported against the arms of the two angle levers by means of a compression spring. Two spring rockers were connected to the two tongue rails via a coupling rod. From the Austrian application A 2137/97, a changeover aid for the elastic locking of movable switch parts has become known, in which locking members are mounted at an axial distance from one another in cages arranged between a tube and a rod, a compression spring acting in the axial direction being arranged between these cages is. The rod is connected to the tongue rails via coupling rods, control grooves being arranged on the circumference of the rod, which move the locking members into their different positions, so that the compression spring is tensioned during the changeover process and a contact pressure is exerted on the tongue rails in the position of the tongue in contact with the groove rails tongue. The ball cages are axially movable to a limited extent, so that use with different tongue impact or different transverse movement of the tongue is possible. In these known devices, the compression spring exerts different forces on the tongue, depending on the span length.
In der EP-AI 603 156 sind verschiedene Verschlußanordnungen und Umstellhilfen beschrieben, wobei ein Antrieb zwischen zwei im wesentlichen ident aufgebauten Umstellhilfen angeordnet wurde. Insgesamt ergibt sich bei derartigen Ausbildungen eine relativ große Baulänge, wodurch der Einsatz bei geringen Spurweiten und insbesondere bei Rillenschienen nicht ohne weiteres möglich ist.EP-AI 603 156 describes various locking arrangements and changeover aids, a drive being arranged between two essentially identical changeover aids. Overall, such designs result in a relatively large overall length, which means that use with small track gauges and in particular with grooved rails is not readily possible.
Aus der FR-A-2 523 537 ist bereits eine Umstellhilfe mit einem integrierten hydraulischen Antrieb bekanntgeworden, wobei Federwippen in Form von zwei Druckfedern ausgebildetn sind, die am Gehäuse des Erdkastens abgestützt werden und nach Überschreiten entsprechender Totpunktslagen wirksam werden. Schließlich ist der EP-AI 0 779 197 eine Einrichtung zur Sicherung der Endlagen von hydraulischen Stellantrieben zu entnehmen.A changeover aid with an integrated hydraulic drive has already become known from FR-A-2 523 537, spring rockers being designed in the form of two compression springs which are supported on the housing of the earth box and take effect after corresponding dead center positions have been exceeded. Finally, EP-AI 0 779 197 shows a device for securing the end positions of hydraulic actuators.
Allen bekannten Einrichtung ist gemeinsam, daß der Verstellhub nicht ohne weiteres verändert und an die jeweiligen Erfordernisse angepaßt werden kann. Die Erfindung zielt nun darauf ab, die Voraussetzungen für eine kompakte kurzbauende Antriebs- und Umstellhilfe zu schaffen, welche insbesondere für den Einsatz bei Rillenschienen aufgrund kurzer Baulänge geeignet ist und sicherstellt, daß die federnde Andrückkraft an die Zunge unabhängig von einem jeweils einstellbaren aktiven Verstellweg wirksam wird, um konstante Andruck- kräfte an die Zunge unabhängig vom Verstellhub erzeugen zu können. Durch die kompakte Baueinheit soll weiters die Möglich- keit eines Auftretens von Querkräften verringert werden, wodurch der Verschleiß wesentlich verringert werden kann.It is common to all known devices that the adjustment stroke cannot be changed easily and adapted to the respective requirements. The invention now aims to create the conditions for a compact short drive and conversion aid, which is particularly suitable for use with grooved rails due to the short length and ensures that the resilient pressing force on the tongue is effective regardless of an adjustable active adjustment path in order to be able to generate constant pressure forces on the tongue regardless of the adjustment stroke. The compact structural unit is also intended to reduce the possibility of transverse forces occurring, as a result of which the wear can be significantly reduced.
Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Ausbildung im wesentlichen darin, daß wenigstens einer der Steueran- schlage in axialer Richtung der Stange verstellbar an der Stange festlegbar ist. Dadurch, daß wenigstens einer der Steueranschläge in axialer Richtung der Stange verstellbar an der Stange festlegbar ist, läßt sich nun in einfacher Weise der Hub und damit der jeweils geforderte Verstellweg einstellen, wobei durch die Verschiebbarkeit und Festlegbarkeit der Steueranschläge gleichzeitig gewährleistet wird, daß am Ende des Hubes jeweils die volle und konstante Federkraft wirksam wird.To achieve this object, the design according to the invention essentially consists in that at least one of the control stops can be fixed on the rod so as to be adjustable in the axial direction of the rod. Characterized in that at least one of the control stops in the axial direction of the rod can be fixed on the rod, the stroke and thus the respectively required adjustment path can now be set in a simple manner, the displaceability and fixability of the control stops simultaneously ensuring that at the end the stroke the full and constant spring force is effective.
Die Ausbildung kann erfindungsgemäß hiebei in besonders ein- facher Weise so getroffen sein, daß die Stange geteilt ausgebildet ist, wobei die axiale Lage eines Stangenteiles, welcher einen Steueranschlag trägt, gegenüber dem anderen Stangenteil veränderbar ist. Die Veränderung der axialen Länge des Stangenteiles unter gleichzeitiger axialer Verlagerung des Steueran- Schlages kann prinzipiell in unterschiedlicher Weise realisiert werden. Wenn die axiale Länge eines Stangenteiles gegenüber dem anderen Stangenteil verändert wird, kann dies beispielsweise so erfolgen, daß ein Stangenteil mit einem Außengewinde und der zweite Stangenteil mit einem Innengewinde ausgebildet ist, wobei der Stangenteil mit dem Außengewinde in den Stangenteil mit dem Innengewinde hinein- oder herausgeschraubt wird. In besonders einfacher Weise kann aber die Ausbildung so getroffen werden, daß der verstellbare Steueranschlag als Stirnfläche einer Hülse ausgebildet ist, welche auf die Stange aufschraubbar und an ihrem freien Ende mit der Koppelstange zum beweglichen Schienenteil verbunden ist. Eine derartig den verstellbaren Steueran- schlag tragende Hülse läßt sich in einfacher Weise auf die Stange aufschrauben und läßt sich auch nachträglich leicht justieren. Vor allen Dingen läßt sich eine derartige Einrichtung auch in besonders einfacher Weise gegen unbeabsichtigte Verstellung sichern und in der jeweils gewählten Position der Hülse arretie- ren bzw. blockieren. Zu diesem Zweck ist die Ausbildung mit Vorzug so getroffen, daß die Hülse ein Innengewinde aufweist, in welches ein ein Außengewinde tragendes Sperrstück nach Art einer Kontermutter im Anschlag an die Stange einschraubbar ist .According to the invention, the design can be made in a particularly simple manner in such a way that the rod is of divided construction, the axial position of a rod part, which carries a control stop, being changeable relative to the other rod part. The change in the axial length of the rod part with simultaneous axial displacement of the control stop can in principle be implemented in different ways. If the axial length of one rod part is changed compared to the other rod part, this can be done, for example, in such a way that one rod part is formed with an external thread and the second rod part is designed with an internal thread, the rod part with the external thread entering or into the rod part with the internal thread is unscrewed. In a particularly simple manner, however, the training can be made that the adjustable control stop is designed as an end face of a sleeve which can be screwed onto the rod and is connected at its free end to the coupling rod to form the movable rail part. Such a sleeve carrying the adjustable control stop can be screwed onto the rod in a simple manner and can also be easily adjusted subsequently. Above all, such a device can also be secured in a particularly simple manner against unintentional adjustment and locked or blocked in the respectively selected position of the sleeve. For this purpose, the design is preferably made such that the sleeve has an internal thread, into which a locking piece carrying an external thread can be screwed into the rod in the manner of a lock nut.
Um nun die Erfordernisse einer besonders kompakten Bauform und damit die bevorzugte Eignung für Rillenschienenweichen zu gewährleisten, ist mit Vorteil die Ausbildung so getroffen, daß der Antrieb von einem in das Rohr koaxial zur Achse oder Stange integrierten und verschieblichen Zylinderkolbenaggregat gebildet ist, deren maximaler Verschiebeweg größer ist als der zulässige Verstellbereich des Steueranschlages bzw. der Hülse. Eine derartige Integration eines hydraulischen Antriebes in die Verstell- und Verriegelungseinrichtung führt zu besonders kurzen Abmessungen und damit gleichzeitig zu einer Verringerung der Gefahr von außermittigen exzentrischen Kräften, welche den Verschleiß erhöhen könnten. Besonders kompakte Ausmaße lassen sich erzielen, wenn der Kolben des Zylinderkolbenaggregates starr mit der Stange verbunden ist, wobei die Kolbenstange mit der die Steueranschläge tragenden Stange ident wird.In order to ensure the requirements of a particularly compact design and thus the preferred suitability for grooved rail switches, the design is advantageously made such that the drive is formed by a cylinder-piston unit integrated and displaceable in the tube coaxial to the axis or rod, the maximum displacement distance of which is greater is the permissible adjustment range of the control stop or sleeve. Such an integration of a hydraulic drive into the adjustment and locking device leads to particularly short dimensions and thus at the same time to a reduction in the risk of eccentric eccentric forces which could increase wear. Particularly compact dimensions can be achieved if the piston of the cylinder-piston unit is rigidly connected to the rod, the piston rod being identified with the rod carrying the control stops.
Eine gegen Eindringen von Staub gesicherte Ausbildung kann dadurch erzielt werden, daß das Rohr beidseitig von Stirnflächen verschlossen ist, wobei in an sich bekannter Weise mit Vorzug die Verriegelungsglieder als Kugeln ausgebildet und in axial verschieblichen Käfigen radial geführt sind, wobei die Feder zwischen den einander zugewandten Stirnflächen der Käfige angeordnet ist. Um auch aus den Endlagen heraus einen sicheren Betrieb der UmStellvorrichtung zu gewährleisten, ist mit Vorteil die Ausbildung so getroffen, daß die Käfige in Endlagen des Verstellweges in Abstand von den Stirnflächen des Rohres liegen.A design secured against the ingress of dust can be achieved in that the tube is closed on both sides by end faces, the locking members preferably being formed as balls in a manner known per se and being guided radially in axially displaceable cages, the spring between the mutually facing ones End faces of the cages is arranged. In order to ensure safe operation of the changeover device even from the end positions, the design is advantageously made such that the cages are in the end positions of the adjustment distance from the end faces of the tube.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert. In dieser zeigen Fig. 1 eine Draufsicht auf eine schematische Anordnung der erfindungsgemäßen Einrichtung und Fig. 2 einen Axialschnitt durch eine Einrichtung zum elastischen Verriegeln und Verstellen von Weichenteilen mit integriertem hydraulischen Antrieb.The invention is explained in more detail below on the basis of an exemplary embodiment shown schematically in the drawing. 1 shows a plan view of a schematic arrangement of the device according to the invention, and FIG. 2 shows an axial section through a device for the elastic locking and adjustment of switch parts with an integrated hydraulic drive.
In Fig. 1 ist eine Rillenschienenweiche ersichtlich, wobei die beweglichen Weichenzungen mit 1 und die Backenschienen mit 2 bezeichnet sind. Die Weichenzungen 1 sind über ein Zungengestänge 3 und Kardangelenke 4 mit der erfindungsgemäßen Einrichtung zum Verstellen und zum elastischen Verriegeln von beweglichen Weichenteilen 5 verbunden. Die Umstellvorrichtung 5 ist mit dem Prüfergestänge 6 in einem ersten U-förmigen offenen Kasten 7 gelagert. Durch die gekoppelte Bauweise der Umstellvorrichtung ist ein Einbau in einem offenen Erdkasten möglich und somit eine leichte Zugänglichkeit für Servicemaßnahmen gegeben. Der elek- trohydraulische Antrieb 8 ist in einem dicht abgeschlossenen separaten Kastenteil 9 an den Kasten 7 fest angebunden. Beide Kastenteile werden mit einer Deckplatte versehen, wobei bei Erfordernis die gesamte Kastenkonstruktion isoliert gegenüber den Schienen eingebettet wird. Vom elektrohydraulischen Antrieb 8 führen Leitungen 10 zu einem in die Umstellvorrichtung 5 integrierten später näher beschriebenen Zylinderkolbenaggregat, welches das Zungengestänge 3 im Sinne des Doppelpfeiles 11 antreibt. Weiters ist in Fig. 1 ersichtlich, daß das parallel angeordnete Prüfergestänge 6 mit Betätigungsplatten 12 versehen ist, welche in der entsprechenden Anlage der Zunge mit induktiven Näherungsschaltern 14 in Kontakt kommen und damit neben der mechanischen auch eine elektrische Überwachung der Anlage ermöglichen. Zur Anpassung an den erforderlichen Hub der Umstellvorrichtung 5 sind die Näherungsschalter 14 so angeordnet, daß ihr Abstand voneinander durch ein Justierglied 13 verändert werden kann.In Fig. 1 a grooved rail switch can be seen, the movable switch tongues being designated 1 and the stock rails being designated 2. The switch tongues 1 are connected via a tongue linkage 3 and universal joints 4 to the device according to the invention for adjusting and elastically locking movable switch parts 5. The switching device 5 is mounted with the tester linkage 6 in a first U-shaped open box 7. Due to the coupled design of the changeover device, installation in an open earth box is possible and thus easy accessibility for service measures. The electro-hydraulic drive 8 is firmly connected to the box 7 in a tightly sealed separate box part 9. Both parts of the box are provided with a cover plate, the entire box construction being embedded insulated from the rails if necessary. Lines 10 lead from the electrohydraulic drive 8 to a cylinder piston unit which is integrated into the changeover device 5 and which is described in more detail below and which drives the tongue linkage 3 in the sense of the double arrow 11. Furthermore, it can be seen in Fig. 1 that the tester linkage 6 arranged in parallel is provided with actuating plates 12 which come into contact with inductive proximity switches 14 in the corresponding system of the tongue and thus in addition to mechanical and also electrical monitoring of the system enable. To adapt to the required stroke of the changeover device 5, the proximity switches 14 are arranged so that their distance from one another can be changed by an adjusting member 13.

Das mit 17 bezeichnete äußere Rohr bildet das Gehäuse für die Umstellvorrichtung. Koaxial zum äußeren Rohr ist eine Stange 15 und eine auf die Stange 15 aufgeschraubte Hülse2, the changeover device is shown in a position in which the tongue rests on the left side on the stock rail. The outer tube designated 17 forms the housing for the changeover device. A rod 15 and a sleeve screwed onto the rod 15 are coaxial with the outer tube
16 angeordnet, welche an ihren freien Enden mit den in Fig. 1 dargestellten Kardangelenken verbunden sind. Im äußeren Rohr 17 sind zwei Zylinderblöcke 19 angeordnet, die einen Zylinderraum 20 begrenzen und diesen nach außen bzw. zum in der Zeichnung linken Teil der Vorrichtung hin dichtend abschließen. Auf die Stange 15 ist im Bereich des Zylinderraumes 20 ein Zylinderkolben 21 aufgeschraubt, welcher mit dem Druck einer Hydaulik- flüssigkeit beaufschlagt werden kann, die über im äußeren Rohr16 arranged, which are connected at their free ends to the universal joints shown in Fig. 1. In the outer tube 17, two cylinder blocks 19 are arranged which delimit a cylinder space 20 and seal it off to the outside or to the part of the device on the left in the drawing. A cylinder piston 21 is screwed onto the rod 15 in the region of the cylinder space 20 and can be pressurized with the pressure of a hydraulic fluid which is in the outer tube
17 vorgesehene Anschlüsse 18 und die in Fig. 1 dargestellten Hydraulikleitungen 10 zu- bzw. abgeführt wird. In seinem linken, dem Zylinderkolbenaggregat benachbarten Abschnitt nimmt das äußere Rohr 17 die Einrichtung zum elastischen Verriegeln der Weichenzunge auf. Die Stange 15 weist an ihrem Umfang eine im Querschnitt trapezförmige Nut 22 auf und hat einen Abschnitt 23 mit kleinerem Durchmesser, welcher Abschnitt 23 zusammen mit der Stirnfläche 25 der auf die Stange 15 aufgeschraubten Hülse 16 eine zweite Nut ausbildet, die im Querschnitt ebenfalls trapezförmig ist. Die Stirnfläche 25 der Hülse 16 bildet gleichzeitig einen Steueranschlag für die radial innere Lage eines ersten Verriegelungsgliedes, das von Kugeln 26 gebildet und in einen axial verschlieblichen Käfig 27 radial geführt wird. Als Anschlag für die radial innere Lage des zweiten Verriegelungsgliedes, welches wiederum aus Kugeln 26' und einem Käfig 27' besteht, wird der Anschlag 24 der Nut 22 wirksam. Die Käfige 27 und 27' weisen jeweils einen Stützring 28 bzw. 28' auf, auf welche sich eine zwischen den Käfigen 27 und 27 ' wirkende Druckfeder 29 abstützt. In das feststehende Außenrohr 17 sind Rohr- stücke 30 und 31 eingeschoben, welche Anschläge 32 und 33 für die radial äußere Lage der Verriegelungsglieder aufweisen. Das Rohrstück 30 stützt sich hiebei am Zylinderblock 19 und das Rohrstück 31 am äußeren Deckel 34 ab, der mit einem Sicherungs- ring 35 in seiner axialen Lage festgelegt ist. Bei einer Umstellbewegung in Richtung des Pfeiles 36 wird zunächst die Feder 29 komprimiert, bis die Verriegelungsglieder 26 sich radial auwärts in den Anschlag 33 verlagern. Die weitere Verschiebung der Stange 15 in Richtung des Pfeiles 36 ist solange frei von jeder Federkrafteinwirkung, bis die Verriegelungsglieder 26' radial einwärts in die Nut 22 der Stange eintreten und mit dem Anschlag 24 derart zusammenwirken, daß die weitere Verschiebung nunmehr durch eine Entspannung der Druckfeder 29 unterstützt wird und daß bei Erreichen der rechten Endlage die federnde Anlage der rechten Zunge unter der Wirkung der Druckfeder 29 gewährleistet ist. Nach Beendigung des Umstellvorganges wird die Hydraulik des Zylinderkolbenaggregates auf Umlauf geschaltet und übt daher keine Kraft auf den Antriebskolben 21 aus. Bei einer Umstellbewegung entgegen der Richtung des Pfeiles 36 wird wiederum die Druckfeder 29, welche sich über das Verriegelungsglied 26 am Anschlag 33 abstützt, über einen kurzen Weg komprimiert, bis das Verriegelungsglied 26' aus der Nut 22 austritt und sich am Anschlag 32 abstützt. Da sich die Druckfeder 29 nun an den beiden ortsfesten Anschlägen 32 und 33 abstützt, ist die weitere Verschiebebewegung frei von Federkräften, bis das Verriegelungsglied 26 in die Nut 23 eintreten kann, worauf die Feder 29 wiederum eine Kraft auf den Steueranschlag 25 ausübt. Bei Erreichen der linken Endlage besitzt der Käfig 27 eine Freistellung f zum Deckel 34, sodaß die Haltekraft der Feder nur auf die Hülse 16 wirkt. Durch Auf- oder Abschrauben der Hülse 16 ändert sich die axiale Lage des Steueranschlages 25 zum Rohr 15, wodurch bei einer Verschiebebewegung entgegen der Richtung des Pfeiles 36 das Verriegelungsglied 26 zu einem anderen Zeitpunkt in die Nut 23 eintreten kann. Bei einer Verschrau- bung der Hülse 16 derart, daß die Länge der Nut 23 verkürzt wird, vergrößert sich der Hub der Umstellvorrichtung, wogegen er sich bei einer Verdrehung der Hülse 16 derart, daß die Länge der Nut 23 vergrößert wird, verringert. Mit der Kontermutter 37 wird die jeweilige Hubeinstellung gesichert. Die Druckfeder 29 hat bei dieser konstruktiven Ausgestaltung in der Endlage jeweils die selbe Gesamtlänge L und übt somit in der Endlage jeweils die selbe Druckkraft auf die Stange 15 bzw. auf die Stirnfläche der Hülse 16 aus. Während des Umstellvorganges wird die Feder 29 geringfügig zusätzlich komprimiert und in der jeweiligen Endlage wieder auf die Länge L entspannt . Es kann somit eine sehr kurze Druckfeder gewählt werden, da nur ein geringer Federweg während des Umstellvorganges benötigt wird. Es ist somit eine lineare Zylinder/Federwippenanordnung vorgesehen, die durch die Rohrbauweise leicht gekapselt und nach außen gedichtet werden kann. Die Einheit ist für einen Stellhub von etwa 35 bis 60 mm einstellbar und gewährleistet über die Druckfeder eine Endlagenfesthalte- kraft von ca. 2600 bis 2800 N. Dadurch, daß die Hydraulik des Zylinderkolbenaggregates in den Endlagen jeweils auf Umlauf geschaltet wird, ermöglicht die Vorrichtung auch eine Zwangsumstellung mit den Spurkränzen der Räder (Auffahren der Weiche) . Die Aufschneidekraft des Umstellmechanismus beträgt etwa 4000 N entsprechend der maximalen Vorspannkraft des Endlagenfesthalte- mechanismus und dem Verschiebewiderstand der Druckfeder des Federwippenmechanismus. Überlastungen oder Beschädigungen an der Stellmechanik können hierbei jedoch nicht auftreten. 17 provided connections 18 and the hydraulic lines 10 shown in FIG. 1 is supplied or discharged. In its left section, which is adjacent to the cylinder piston unit, the outer tube 17 receives the device for elastically locking the switch tongue. The rod 15 has on its circumference a groove 22 which is trapezoidal in cross section and has a section 23 with a smaller diameter, which section 23 together with the end face 25 of the sleeve 16 screwed onto the rod 15 forms a second groove which is also trapezoidal in cross section . The end face 25 of the sleeve 16 also forms a control stop for the radially inner position of a first locking member, which is formed by balls 26 and is guided radially into an axially displaceable cage 27. The stop 24 of the groove 22 acts as a stop for the radially inner position of the second locking member, which in turn consists of balls 26 'and a cage 27'. The cages 27 and 27 'each have a support ring 28 or 28', on which a compression spring 29 is supported, which acts between the cages 27 and 27 '. In the fixed outer tube 17 are tube Pieces 30 and 31 inserted, which have stops 32 and 33 for the radially outer position of the locking members. The pipe section 30 is supported on the cylinder block 19 and the pipe section 31 on the outer cover 34, which is fixed in its axial position with a retaining ring 35. When changing over in the direction of arrow 36, the spring 29 is first compressed until the locking members 26 are displaced radially outward into the stop 33. The further displacement of the rod 15 in the direction of arrow 36 is free from any spring force until the locking members 26 'enter radially inward into the groove 22 of the rod and cooperate with the stop 24 in such a way that the further displacement is now due to a relaxation of the compression spring 29 is supported and that when the right end position is reached, the resilient contact of the right tongue is ensured under the action of the compression spring 29. After the changeover process has ended, the hydraulic system of the cylinder-piston unit is switched to circulation and therefore does not exert any force on the drive piston 21. In the event of a changeover movement in the direction of the arrow 36, the compression spring 29, which is supported on the stop 33 via the locking member 26, is compressed over a short distance until the locking member 26 'emerges from the groove 22 and is supported on the stop 32. Since the compression spring 29 is now supported on the two fixed stops 32 and 33, the further displacement movement is free of spring forces until the locking member 26 can enter the groove 23, whereupon the spring 29 in turn exerts a force on the control stop 25. When the left end position is reached, the cage 27 has an exemption f from the cover 34, so that the holding force of the spring acts only on the sleeve 16. By screwing on or unscrewing the sleeve 16, the axial position of the control stop 25 relative to the tube 15 changes, as a result of which the locking member 26 can enter the groove 23 at a different time during a displacement movement against the direction of the arrow 36. When the sleeve 16 is screwed in such a way that the length of the groove 23 is shortened, the stroke of the changeover device increases, whereas when the sleeve 16 is rotated it increases in such a way that the length of the Groove 23 is enlarged, reduced. The respective stroke setting is secured with the lock nut 37. The compression spring 29 has the same total length L in the end position in this construction and thus exerts the same pressure force on the rod 15 or on the end face of the sleeve 16 in the end position. During the changeover process, the spring 29 is additionally compressed slightly and relaxed again to the length L in the respective end position. A very short compression spring can thus be selected, since only a small spring travel is required during the changeover process. A linear cylinder / spring rocker arrangement is thus provided, which can be easily encapsulated by the tubular construction and sealed to the outside. The unit can be adjusted for an adjustment stroke of approx. 35 to 60 mm and guarantees an end position holding force of approx. 2600 to 2800 N via the compression spring. The fact that the hydraulic system of the cylinder piston unit is switched to the end position also enables the device a forced changeover with the wheel flanges (opening of the switch). The cutting force of the changeover mechanism is approximately 4000 N, corresponding to the maximum preload force of the end position retaining mechanism and the displacement resistance of the compression spring of the spring rocker mechanism. However, overloading or damage to the actuating mechanism cannot occur.
