Description

Die Erfindung betrifft eine Vorrichtung zum horizontalen Verstellen einer relativ zu einer Stützstruktur verschwenkbaren Kupplungsstange in eine vorab festgelegte oder festlegbare Stellung, insbesondere Mittenstellung. Insbesondere betrifft die Erfindung eine Vorrichtung zur horizontalen Mittenrückstellung einer Kupplungsstange, insbesondere einer Mittelpufferkupplung, eines spurgeführten Fahrzeugs.The invention relates to a device for horizontally adjusting a coupling rod that can be pivoted relative to a support structure into a predetermined or definable position, in particular a central position. In particular, the invention relates to a device for the horizontal center resetting of a coupling rod, in particular a center buffer coupling, of a track-guided vehicle.

Devices for center resetting are known, for example, from the following publications:

  • DE 2 419 184 A1
  • DE 2 822 104 A1
  • DE 2 445 460 A1
  • DE 2 846 860 A1
  • US 3,578,180 A
  • US 4,569,455 A

Im Einzelnen zeigt die DE 1 810 593 B2 eine Vorrichtung zur horizontalen Mittenrückstellung für eine mittels einer Kupplungsstange schwenkbar an einem Schienenfahrzeug angebrachte Mittelpufferkupplung mit einer die Schwenkbewegung der Kupplungsstange um seine vertikale Schwenkachse mitmachende Führung. Symmetrisch zur Längsachse der Kupplungsstange sind an Führungen schräge Druckflächen angeordnet.In detail it shows DE 1 810 593 B2 a device for horizontal center resetting for a center buffer coupling which is pivotably attached to a rail vehicle by means of a coupling rod, with a guide which follows the pivoting movement of the coupling rod about its vertical pivot axis. Sloping pressure surfaces are arranged on guides symmetrically to the longitudinal axis of the coupling rod.

Federnde Druckeinrichtungen, die sich am Gehäuse für die Kupplungsstange abstützen und die horizontale Mittenrückstellung bewirken, weisen jeweils eine Rückstellfeder, ein von der Rückstellfeder beaufschlagtes und mit einer der Druckflächen zusammenwirkendes, eine Rolle tragendes Druckübertragungsglied und ein die Bewegung des Druckübertragungsgliedes begrenzendes Anschlagglied auf, wobei jeder Druckfläche eine Druckeinrichtung zugeordnet ist.Resilient pressure devices, which are supported on the housing for the coupling rod and effect the horizontal center reset, each have a return spring, a pressure transmission member which is acted upon by the return spring and interacts with one of the pressure surfaces and carries a roller, and a stop member which limits the movement of the pressure transmission member, each A printing device is assigned to the printing surface.

Aus der DE 2 419 184 A1 ist eine weitere Vorrichtung zum horizontalen Mittenrückstellung einer Mittelpufferkupplung für Schienenfahrzeuge bekannt, bei der symmetrisch beiderseits der Kupplungsachse je eine Druckfeder angeordnet ist, die jeweils an einem in einem Gehäuse geführtes Gleitstück anliegt. Die Gleitstücke sind jeweils über eine zugehörige Stützrolle mit vertikaler Achse durch die Kraft der vorgespannten Druckfedern gegen eine die horizontale Schwenkbewegung der Kupplungsstange um die vertikale Schwenkachse der Mittelpufferkupplung mitmachende Führung angedrückt.From the DE 2 419 184 A1 a further device for the horizontal center reset of a center buffer coupling for rail vehicles is known, in which A compression spring is arranged symmetrically on both sides of the coupling axis, each of which rests on a slider guided in a housing. The sliders are each pressed via an associated support roller with a vertical axis by the force of the prestressed compression springs against a guide that follows the horizontal pivoting movement of the coupling rod about the vertical pivot axis of the central buffer coupling.

Die Stützrollen bilden symmetrisch beiderseits der Kupplungsachse je ein in der Führung gelagertes Stützrollenpaar, dessen beide Stützrollen jeweils unterschiedliche Abstände von der Kupplungsachse aufweisen, wobei die Achsen der Stützrollen auf einem zur vertikalen Schwenkachse der Mittelpufferkupplung konzentrischen Kreis liegen. In der Mittenstellung der Mittelpufferkupplung liegen diese Stützrollen jedes Stützrollenpaares jeweils an einer Gleitfläche des in Draufsicht etwa dreieckförmigen Gleitstückes an, wobei an jedem Gleitstück ein Führungsschaft angeordnet ist, der das Gehäuse durchdringt und in diesem geführt ist.The support rollers form symmetrically on both sides of the coupling axis a pair of support rollers mounted in the guide, the two support rollers of which are each at different distances from the coupling axis, the axes of the support rollers lying on a circle concentric to the vertical pivot axis of the central buffer coupling. In the middle position of the central buffer coupling, these support rollers of each pair of support rollers each rest on a sliding surface of the slider, which is approximately triangular in plan view, with a guide shaft being arranged on each slider, which penetrates the housing and is guided in it.

Im normalen Betrieb, d.h. auch bei Durchfahren von Kurven oder Weichen, ist die Mittenstellvorrichtung ständig wirksam, so dass sich an den Gleitflächen der Gleitstücke, die durch die Druckfedern gegen die Stützrollen gedrückt werden, durch die Schwenkbewegung der Mittelpufferkupplung ein relativ großer Verschleiß ergibt. Ein Kuppeln in einer Kurve ist nur mit Schwierigkeiten oder gar nicht möglich, da hier die Rückstellkräfte der Druckfedern dem manuell bewirkten Ausschwenken der zu kuppelnden Mittelpufferkupplung entgegenwirken. Um die Mittenrückstellung DE 2 419 184 A1 ausschalten zu können greift in DE 2 822 104 A1 das Gleitstück an einen doppelarmigen Schwenkhebel an, dessen einer Hebelarm direkt oder indirekt mit einem Hubzylinder verbunden ist und dessen anderer Hebelarm gegen das Gehäuse anliegt.During normal operation, ie even when driving through curves or switches, the center adjusting device is constantly active, so that the pivoting movement of the center buffer coupling results in relatively large wear on the sliding surfaces of the sliders, which are pressed against the support rollers by the compression springs. Coupling in a curve is only possible with difficulty or not at all, since the restoring forces of the compression springs counteract the manually effected swinging out of the center buffer coupling to be coupled. About the center reset DE 2 419 184 A1 Being able to switch it off comes into play DE 2 822 104 A1 the slider to a double-armed swivel lever, one lever arm of which is directly or indirectly connected to a lifting cylinder and the other lever arm rests against the housing.

Bei sämtlichen, zuvor diskutierten Lösungen kommen Mittenrückstellungen zum Einsatz, die einen relativ großen Bauraum benötigen, der jedoch häufig nicht in dem Bereich der Schnittstelle zwischen der Kupplungsstange und dem Wagenkasten bzw. Untergestell des spurgeführten Fahrzeugs zur Verfügung steht.In all of the previously discussed solutions, center resets are used, which require a relatively large installation space, which, however, is often not available in the area of the interface between the coupling rod and the car body or underframe of the track-guided vehicle.

Das grundlegende Funktionsprinzip bei den zuvor diskutierten und allgemein aus dem Stand der Technik bekannten Mittenstelleinrichtungen besteht darin, dass ein krafterzeugendes Element, wie beispielsweise ein Pneumatikzylinder oder ein mechanisches Federpaket, ein geeignetes Element, wie beispielsweise eine Rolle, gegen eine geeignete Kurvenbahn drückt und so ein Drehmoment erzeugt, mit dem die ungekuppelte Kupplung horizontal in der Mittelachse gehalten wird.The basic operating principle in the center adjusting devices discussed above and generally known from the prior art is that a force-generating element, such as a pneumatic cylinder or a mechanical spring assembly, is a suitable element, such as a Roller, presses against a suitable cam path and thus generates a torque with which the uncoupled clutch is held horizontally in the central axis.

Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zum horizontalen Verstellen einer relativ zu einer Stützstruktur verschwenkbaren Kupplungsstange in eine vorab festgelegte oder festlegbare Stellung, insbesondere Mittenstellung, anzugeben, die aufgrund ihres kompakten Aufbaus nur einen relativ geringen Bauraum benötigt.The invention is based on the object of specifying a device for horizontally adjusting a coupling rod that can be pivoted relative to a support structure into a predetermined or definable position, in particular a central position, which only requires a relatively small amount of installation space due to its compact structure.

Insbesondere soll eine Vorrichtung zum horizontalen Verstellen einer Kupplungsstange angegeben werden, die sich durch einen technisch einfach zu realisierenden Aufbau auszeichnet, wobei insbesondere ein Verschleiß des krafterzeugenden Elements (Pneumatikzylinder oder mechanisches Federpaket), welches das zum Verstellen der Kupplungsstange notwendige Drehmoment generiert, reduziert werden kann.In particular, a device for the horizontal adjustment of a coupling rod is to be specified, which is characterized by a structure that is technically easy to implement, and in particular wear of the force-generating element (pneumatic cylinder or mechanical spring assembly), which generates the torque required to adjust the coupling rod, can be reduced .

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des unabhängigen Patentanspruches 1 gelöst, wobei vorteilhafte Weiterbildungen hiervon in den abhängigen Ansprüchen angegeben sind.This object is achieved according to the invention by the subject matter of independent patent claim 1, advantageous developments thereof being specified in the dependent claims.

Demgemäß betrifft die Erfindung insbesondere eine Vorrichtung zum horizontalen Verstellen einer relativ zu einer Stützstruktur verschwenkbaren Kupplungsstange in eine vorab festgelegte oder festlegbare Stellung, insbesondere Mittenstellung, wobei die Vorrichtung eine mit der Kupplungsstange wirkverbundene Führung und mindestens einen Druckkörper aufweist, welcher ausgebildet ist, zumindest bedarfsweise mit der Führung derart zusammenzuwirken, dass auf die Führung ein zum Verstellen der Kupplungsstange erforderliches Drehmoment wirkt. Hierzu ist dem mindestens einem Druckkörper eine Druckeinrichtung zugeordnet, um zumindest bedarfsweise eine auf den mindestens einen Druckkörper wirkende Druckkraft bereitzustellen.Accordingly, the invention relates in particular to a device for horizontally adjusting a coupling rod which can be pivoted relative to a support structure into a predetermined or definable position, in particular a central position, the device having a guide which is operatively connected to the coupling rod and at least one pressure body which is designed, at least if necessary, with interact with the guide in such a way that a torque required to adjust the coupling rod acts on the guide. For this purpose, a pressure device is assigned to the at least one pressure body in order to provide, at least if necessary, a pressure force acting on the at least one pressure body.

Die erfindungsgemäße Lösung zeichnet sich insbesondere dadurch aus, dass die dem mindestens einem Druckkörper zugeordnete Druckeinrichtung nicht unmittelbar, d.h. direkt, mit dem zugeordneten Druckkörper zusammenwirkt, sondern über einen Hebelmechanismus mit dem mindestens einem Druckkörper wirkverbunden ist.The solution according to the invention is characterized in particular by the fact that the printing device assigned to the at least one pressure body does not interact directly, ie directly, with the assigned pressure body, but is operatively connected to the at least one pressure body via a lever mechanism.

Durch die mechanische Entkopplung der Druckeinrichtung von dem mindestens einem Druckkörper sind mehrere Vorteile erzielbar. Insbesondere ist es mit dem erfindungsgemäßen Aufbau nicht mehr notwendig, dass die Druckeinrichtung unmittelbar an dem mindestens einem Druckkörper und somit in unmittelbarer Nähe zu der mit der Kupplungsstange wirkverbundenen Führung angeordnet ist. Vielmehr kann die Druckeinrichtung außerhalb des Bereiches der Schnittstelle zwischen der Kupplungsstange und der Stützstruktur, wie beispielsweise dem Wagenkasten bzw. Untergestellt des spurgeführten Fahrzeuges, angeordnet werden. Auf diese Weise wird für die Verstellvorrichtung weniger Bauraum im Schnittstellenbereich zwischen der Kupplungsstange und dem Wagenkasten bzw. der Stützstruktur benötigt.Several advantages can be achieved by mechanically decoupling the printing device from the at least one pressure body. In particular, with the structure according to the invention, it is no longer necessary for the printing device to be arranged directly on the at least one pressure body and thus in the immediate vicinity of the guide operatively connected to the coupling rod. Rather, the printing device can be arranged outside the area of the interface between the coupling rod and the support structure, such as the car body or the base of the track-guided vehicle. In this way, less installation space is required for the adjustment device in the interface area between the coupling rod and the car body or the support structure.

Abgesehen hiervon zeichnet sich die erfindungsgemäße Lösung dadurch aus, dass die Druckeinrichtung unabhängig von der Richtung, in welcher der der Druckeinrichtung geordnete Druckkörper wirkt, angeordnet werden kann.Apart from this, the solution according to the invention is characterized in that the printing device can be arranged independently of the direction in which the pressure body assigned to the printing device acts.

Auf diese Weise kann wirksam verhindert werden, dass bei der Betätigung der Druckeinrichtung Torsion- oder Biegebelastungen auf die Druckeinrichtung wirken. Dadurch, dass bei Betätigung der Druckeinrichtung keine Biegebelastung auf die Druckeinrichtung wirkt, können als Druckeinrichtung Standardkomponenten, insbesondere Standard-Pneumatikzylinder, verwendet werden. Damit sind besonders kompakt bauende und insbesondere auch kostengünstige Verstellvorrichtungen realisierbar.In this way, it can be effectively prevented that torsional or bending loads act on the printing device when the printing device is actuated. Because no bending load acts on the printing device when the printing device is actuated, standard components, in particular standard pneumatic cylinders, can be used as the printing device. This makes it possible to implement particularly compact and, in particular, cost-effective adjustment devices.

Durch die Verwendung eines Hebelmechanismus, über den die Druckeinrichtung mit dem mindestens einem Druckkörper wirkverbunden ist, ist darüber hinaus eine Kraftverstärkung durch die Hebelverhältnisse des Hebelmechanismus möglich und insbesondere auch bedarfsweise einstellbar.By using a lever mechanism, via which the pressure device is operatively connected to the at least one pressure body, a force amplification through the lever ratios of the lever mechanism is also possible and, in particular, can also be adjusted if necessary.

In einer bevorzugten Realisierung der erfindungsgemäßen Verstellvorrichtung weist der Hebelmechanismus mindestens einen Hebelarm auf, wobei ein erster Endbereich des Hebelarms in einer horizontalen Ebene verschwenkbar mit der Druckeinrichtung verbunden ist, und wobei ein dem ersten Endbereich gegenüberliegender zweiter Endbereich des Hebelarms in einer horizontalen Ebene verschwenkbar mit der Stützstruktur verbunden ist. Als Stützstruktur im Sinne der vorliegenden Erfindung eignet sich beispielsweise der Wagenkasten oder ein Untergestell des Wagenkastens oder ein Lagerbock.In a preferred implementation of the adjusting device according to the invention, the lever mechanism has at least one lever arm, wherein a first end region of the lever arm is pivotally connected to the printing device in a horizontal plane, and wherein a second end region of the lever arm, which is opposite the first end region, is pivotally connected to the in a horizontal plane Support structure is connected. For example, the car body or a subframe of the car body or a bearing block is suitable as a support structure in the sense of the present invention.

Bei dieser Ausführungsform ist es insbesondere denkbar, dass der mindestens eine Druckkörper in einem Bereich zwischen dem ersten und dem zweiten Endbereich des Hebelarms angeordnet ist. Vorzugsweise ist eine Position des mindestens einen Druckkörpers zwischen dem ersten und dem zweiten Endbereich des Hebelarms einstellbar, um auf diese Weise die Hebelverhältnisse des Hebelmechanismus zu variieren und eine Kraftverstärkung der Druckeinrichtung einzustellen.In this embodiment, it is particularly conceivable that the at least one pressure body is arranged in a region between the first and second end regions of the lever arm. Preferably, a position of the at least one pressure body between the first and the second end region of the lever arm is adjustable in order to vary the lever ratios of the lever mechanism and to set a force amplification of the pressure device.

Bevorzugt kommen bei der erfindungsgemäßen Verstellvorrichtung mindestens zwei Druckkörper zum Einsatz, die vorzugsweise symmetrisch zur Längsachse der Kupplungsstange angeordnet sind, und die jeweils zum bedarfsweisen Erzeugen eines auf die mit der Kupplungsstange wirkverbundene Führung wirkendes Drehmoment dienen.In the adjusting device according to the invention, at least two pressure bodies are preferably used, which are preferably arranged symmetrically to the longitudinal axis of the coupling rod, and which each serve to generate a torque acting on the guide operatively connected to the coupling rod as required.

Bei dieser Ausführungsform bietet es sich an, dass der Hebelmechanismus zwei parallel zueinander verlaufende Hebelarme aufweist, die jeweils einen ersten Endbereich aufweisen, der in einer horizontalen Ebene verschwenkbar mit der Druckeinrichtung verbunden ist. Darüber hinaus weisen die beiden Hebelarme des Hebelmechanismus jeweils einen dem ersten Endbereich gegenüberliegenden zweiten Endbereich auf, der jeweils in einer horizontalen Ebene verschwenkbar mit der Stützstruktur verbunden ist.In this embodiment, it is advisable for the lever mechanism to have two lever arms running parallel to one another, each of which has a first end region which is pivotably connected to the printing device in a horizontal plane. In addition, the two lever arms of the lever mechanism each have a second end region opposite the first end region, which is each pivotally connected to the support structure in a horizontal plane.

Bei dieser Realisierung ist die Druckeinrichtung vorzugsweise freischwebend zwischen den beiden ersten Endbereichen der beiden Hebelarme angeordnet, insbesondere eingespannt.In this implementation, the printing device is preferably arranged, in particular clamped, in a freely floating manner between the two first end regions of the two lever arms.

Beispielsweise kann die Druckeinrichtung eine zwischen dem ersten und zweiten Hebelarm eingespannte Druckfeder aufweisen, wobei diese Druckfeder insbesondere zwischen den beiden Endbereichen der beiden Hebelarme angeordnet, insbesondere eingespannt ist.For example, the printing device can have a compression spring clamped between the first and second lever arms, this compression spring being arranged, in particular clamped, between the two end regions of the two lever arms.

Allerdings ist die Erfindung nicht auf Ausführungsformen beschränkt, bei welcher als Druckeinrichtung eine Druckfeder zum Einsatz kommt. Vielmehr ist gemäß bevorzugten Realisierungen vorgesehen, dass die Druckeinrichtung einen linear wirkenden Aktuator aufweist, welcher ausgebildet ist, bedarfsweise eine zumindest teilweise quer zur Längsachse der Kupplungsstange wirkende Druckkraft zu generieren. Der Aktuator ist insbesondere derart ausgeführt, dass dieser bedarfsweise ein- bzw. abgeschaltet werden kann, so dass nur dann mit Hilfe der Druckeinrichtung und den zugeordneten Druckkörpern ein zum Verstellen der Kupplungsstange notwendiges Drehmoment generiert wird, wenn tatsächlich ein horizontales Verstellen der Kupplungsstange notwendig ist.However, the invention is not limited to embodiments in which a compression spring is used as the pressure device. Rather, according to preferred implementations, it is provided that the printing device has a linearly acting actuator, which is designed, if necessary, to generate a pressure force acting at least partially transversely to the longitudinal axis of the coupling rod. The actuator is designed in particular in such a way that it can be used as needed can be switched on or off, so that a torque necessary for adjusting the coupling rod is only generated with the help of the pressure device and the associated pressure bodies if a horizontal adjustment of the coupling rod is actually necessary.

Als Aktuator bietet sich beispielsweise ein Pneumatik- oder Hydraulikzylinder an, wobei allerdings auch elektromotorische Aktuatoren grundsätzlich geeignet wären.A pneumatic or hydraulic cylinder, for example, can be used as an actuator, although electric motor actuators would also generally be suitable.

Insbesondere bei Ausführungsformen, bei denen zwei parallel zueinander verlaufende Hebelarme als Hebelmechanismus zum Einsatz kommen, ist der Aktuator der Druckeinrichtung zwischen den beiden ersten Endbereichen der beiden Hebelarme angeordnet, insbesondere eingespannt, und vorzugsweise freischwebend gelagert.In particular in embodiments in which two mutually parallel lever arms are used as a lever mechanism, the actuator of the printing device is arranged between the two first end regions of the two lever arms, in particular clamped, and preferably mounted in a freely floating manner.

Im Hinblick auf die mit der Kupplungsstange wirkverbundene Führung der erfindungsgemäßen Verstellvorrichtung ist erfindungsgemäß vorgesehen, dass die Führung einen dem mindestens einem Druckkörper zugeordneten Bereich aufweist, welcher eine derart zu dem Drucckörper komplementär ausgeführte Formgebung und/oder Kontur aufweist, dass ein zum Verstellen der Kupplungsstange erforderliches Drehmoment auf die Führung wirkt, wenn der Druckkörper mit Hilfe der Druckeinrichtung in den ihm zugeordneten Bereich gedrückt wird.With regard to the guide of the adjusting device according to the invention, which is operatively connected to the coupling rod, it is provided according to the invention that the guide has an area assigned to at least one pressure body, which has a shape and / or contour that is complementary to the pressure body in such a way that a required for adjusting the coupling rod Torque acts on the guide when the pressure body is pressed into the area assigned to it using the pressure device.

Erfindungsgemäß sind der Druckkörper und der dem Druckkörper zugeordnete Bereich der Führung ausgeführt, zumindest bereichsweise eine formschlüssige Paarung auszubilden, wenn der Druckkörper in den ihm zugeordneten Bereich gedrückt wird.According to the invention, the pressure body and the area of the guide assigned to the pressure body are designed to form a positive pairing at least in some areas when the pressure body is pressed into the area assigned to it.

Erfindungsgemäß ist vorgesehen, dass die Führung zumindest bereichsweise als Kurvenscheibe ausgebildet ist, die um einen vertikal verlaufenden Schwenkbolzen relativ zu der Stützstruktur gelagert und mit der Kupplungsstange drehsynchron gekoppelt ist. Durch die Ausgestaltung der Führung als eine um den vertikal angeordneten Schwenkbolzen drehbare Kurvenscheibe, wird eine besonders einfach und leicht zu realisierende Möglichkeit angegeben, um ein Verschwenken der Kupplungsstange mittels der Verschwenkvorrichtung zu bewirken bzw. eine Führung zu realisieren, welche eine horizontale Schwenkbewegung der Kupplungsstange um eine vertikale Schwenkachse mitmacht. Selbstverständlich sind hier aber auch andere Ausführungsformen grundsätzlich denkbar.According to the invention, it is provided that the guide is designed, at least in some areas, as a cam disk, which is mounted relative to the support structure around a vertically extending pivot pin and is coupled in a rotationally synchronous manner to the coupling rod. By designing the guide as a cam that can be rotated about the vertically arranged pivot pin, a particularly simple and easy-to-implement option is provided for pivoting the coupling rod by means of the pivoting device or a guide to realize which involves a horizontal pivoting movement of the coupling rod about a vertical pivot axis. Of course, other embodiments are also fundamentally conceivable here.

Um zu erreichen, dass sich die Druckeinrichtung nach dem Erreichen einer Endlage bzw. nach dem Erreichen der in dem Schwenkbereich der Mittelpufferkupplung vorgesehenen Endposition selbstständig abschaltet, ist in einer besonders bevorzugten Ausführungsform vorgesehen, dass im Bereich einer Mittenstellung der Kupplungsstange eine Einrichtung vorgesehen ist, die das Abschalten der Druckeinrichtung angibt. Insbesondere ist es denkbar, dass die Druckeinrichtung nach Erreichen der Mittenstellung der Kupplungsstange sich selbstständig abschaltet.In order to ensure that the printing device switches off automatically after reaching an end position or after reaching the end position provided in the pivoting range of the central buffer coupling, it is provided in a particularly preferred embodiment that a device is provided in the area of a central position of the coupling rod indicates the switching off of the printing device. In particular, it is conceivable that the printing device switches off automatically after the coupling rod has reached the central position.

Allgemein ist die Vorrichtung im unbelasteten Zustand, d.h. bei unausgelenkter Kupplungsstange, durch einen symmetrischen Aufbau hinsichtlich der Grundkomponenten Führung, Druckkörper und Hebelarme charakterisiert. Die Führung ist mit der Kupplungsstange wenigstens mittelbar, vorzugsweise direkt verbindbar. Die Hebelarme wirken über formschlüssig mit der Führung zusammenwirkende Druckkörper auf diese unter Erzeugung eines Drehmomentes ein.In general, the device in the unloaded state, i.e. with the coupling rod undeflected, is characterized by a symmetrical structure with regard to the basic components of the guide, pressure body and lever arms. The guide can be connected to the coupling rod at least indirectly, preferably directly. The lever arms act on the guide via pressure bodies that interact positively with the guide to generate a torque.

Die Vorrichtung ist durch eine Erstreckung in Längsrichtung charakterisiert, welche im Einbauzustand mit der Längsrichtung der Kupplungsstange zusammenfällt. Die Hebelarme sind dazu in einer horizontalen Ebene beidseitig einer theoretischen Längsachse angeordnet und weisen einen Bereich auf, insbesondere Endbereich auf, welcher mit der Stützstruktur drehgelenkig verbindbar ist. Die Hebelarme weisen ferner einen Bereich zum wenigstens mittelbaren Einwirken auf die Führung auf. Dieser kann als Einwirkbereich bezeichnet werden und ist durch die Anordnung der Druckkörper charakterisiert. Zur Erzeugung der erforderlichen Kraft auf die Führung ist die Druckeinrichtung zur Beaufschlagung der Hebelarme vorgesehen. Diese kann in Längsrichtung der Vorrichtung betrachtet zwischen dem Anbindungsbereich an die Stützstruktur und dem Einwirkungsbereich oder aber dem Einwirkungsbereich nachgeordnet sein. Die Druckeinrichtung ist im einfachsten Fall zwischen den Hebelarmen angeordnet und weist einen linear wirkenden Aktuator auf, welche eine quer zur Längsachse der Kupplungsstange und Längsachse der Vorrichtung wirkende Kraft auf die Hebelarme generiert. In der Regel wird diese eine Zugkraft sein, welche die Hebel aufeinander zuzieht und somit den Einwirkbereich nach Art einer Zange auf die Führung wirken lassen wird.The device is characterized by an extension in the longitudinal direction, which, when installed, coincides with the longitudinal direction of the coupling rod. For this purpose, the lever arms are arranged in a horizontal plane on both sides of a theoretical longitudinal axis and have an area, in particular an end area, which can be connected to the support structure in a pivoting manner. The lever arms also have an area for at least indirectly influencing the guide. This can be referred to as the impact area and is characterized by the arrangement of the pressure bodies. To generate the required force on the guide, the pressure device is provided to act on the lever arms. Viewed in the longitudinal direction of the device, this can be arranged between the connection area to the support structure and the area of influence or downstream of the area of action. In the simplest case, the printing device is arranged between the lever arms and has a linearly acting actuator, which generates a force acting on the lever arms transversely to the longitudinal axis of the coupling rod and the longitudinal axis of the device. As a rule, this will be a tensile force that pulls the levers towards each other and thus causes the area of influence to act on the guide in the manner of pliers.

Die Erfindung betrifft nicht nur eine Verschwenkvorrichtung der zuvor genannten Art, sondern auch eine Mittelpufferkupplung eines spurgeführten Fahrzeugs, insbesondere Schienenfahrzeugs, mit einer relativ zu einer Stützstruktur verschwenkbaren Kupplungsstange und der erfindungsgemäßen Verstellvorrichtung zum horizontalen Verstellen der Kupplungsstange in eine vorab festgelegte oder festlegbare Stellung, insbesondere Mittenstellung.The invention relates not only to a pivoting device of the type mentioned above, but also to a center buffer coupling of a track-guided vehicle, in particular a rail vehicle, with a coupling rod which can be pivoted relative to a support structure and the adjusting device according to the invention for horizontally adjusting the coupling rod into a predetermined or definable position, in particular a central position .

Nachfolgend wird unter Bezugnahme auf die in FIG. 1a gezeigte Prinzipskizze eine erste exemplarische Ausführungsform der erfindungsgemäßen Verstellvorrichtung 1 näher beschrieben.Below is with reference to the in FIG. 1a The schematic diagram shown describes a first exemplary embodiment of the adjusting device 1 according to the invention in more detail.

Im Einzelnen dient die Verstellvorrichtung 1 zum horizontalen Verstellen einer relativ zu einer Stützstruktur 2 verschwenkbaren Kupplungsstange (in FIG. 1a ist die Kupplungsstange nicht explizit gezeigt) in eine vorab festgelegte oder festlegbare Stellung, insbesondere Mittenstellung.In detail, the adjusting device 1 is used to horizontally adjust a coupling rod (in FIG. 1a is the coupling rod not explicitly shown) into a predetermined or definable position, in particular a central position.

Die schematisch in FIG. 1a gezeigte Verstellvorrichtung 1 eignet sich insbesondere als eine Mittenstelleinrichtung für Kupplungen bei spurgeführten Fahrzeugen, insbesondere Schienenfahrzeugen.The schematic in FIG. 1a Adjusting device 1 shown is particularly suitable as a center adjusting device for couplings in track-guided vehicles, in particular rail vehicles.

Mittenstelleinrichtungen werden bei Kupplungen für Schienenfahrzeuge benötigt, um die Kupplung im ungekuppelten Zustand horizontal in der Mittelachse (Längsachse des Fahrzeugs) zu halten. Das ist notwendig, um einerseits ein Anschlagen der Kupplung am Fahrzeug während der Fahrt zu verhindern (Querbeschleunigung) und andererseits das automatische Kuppeln der Kupplungen zu ermöglichen, und zwar indem die Kupplungen gegeneinander gefahren werden.Center adjusting devices are required for couplings for rail vehicles in order to hold the coupling horizontally in the central axis (longitudinal axis of the vehicle) when uncoupled. This is necessary, on the one hand, to prevent the clutch from hitting the vehicle while driving (lateral acceleration) and, on the other hand, to enable automatic coupling of the clutches by moving the clutches against each other.

Das grundlegende Funktionsprinzip der aus dem Stand der Technik bekannten Mittenstelleinrichtungen besteht darin, dass ein krafterzeugendes Element, wie beispielsweise ein Pneumatikzylinder oder ein mechanisches Federpaket, ein geeignetes Element, zum Beispiel eine Rolle, gegen eine geeignete Kurvenbahn drückt und so ein Drehmoment erzeugt, mit welchem die ungekuppelte Kupplung horizontal in der Mittelachse gehalten wird.The basic functional principle of the center adjusting devices known from the prior art is that a force-generating element, such as a pneumatic cylinder or a mechanical spring assembly, presses a suitable element, for example a roller, against a suitable cam track and thus generates a torque with which the uncoupled coupling is held horizontally in the central axis.

Die erfindungsgemäße Verstellvorrichtung 1 dient somit insbesondere dazu, Kupplungen im ungekuppelten Zustand in der horizontalen Mittellage zu halten bzw. aus einer horizontal ausgelenkten Position wieder in die Mittellage zurückzuschwenken.The adjusting device 1 according to the invention thus serves in particular to hold couplings in the horizontal central position in the uncoupled state or to pivot them back into the central position from a horizontally deflected position.

Die erfindungsgemäße Verstellvorrichtung 1, die gemäß der in FIG. 1a schematisch dargestellten Prinzipskizze anhand einer exemplarischen Ausführungsform gezeigt ist, zeichnet sich insbesondere durch ihren technisch einfachen, leichten und kompakt gebauten Aufbau aus.The adjusting device 1 according to the invention, which according to in FIG. 1a schematically illustrated schematic sketch based on an exemplary embodiment, is characterized in particular by its technically simple, light and compact structure.

Im Einzelnen weist die Verstellvorrichtung 1 eine mit der in FIG. 1a nicht explizit dargestellten Kupplungsstange wirkverbundene Führung 3 sowie mindestens einen Druckkörper 4 auf, welcher ausgebildet ist, zumindest bedarfsweise mit der Führung 3 derart zusammenzuwirken, dass auf die Führung 3 ein zum Verstellen der Kupplungsstange erforderliches Drehmoment wirkt.In detail, the adjustment device 1 has one with the in FIG. 1a not explicitly shown coupling rod operatively connected guide 3 and at least one pressure body 4, which is designed, at least if necessary, to interact with the guide 3 in such a way that a torque required to adjust the coupling rod acts on the guide 3.

Darüber hinaus weist die erfindungsgemäße Verstellvorrichtung 1 eine dem mindestens einem Druckkörper 4 zugeordnete Druckeinrichtung 5 auf, um zumindest bedarfsweise eine auf den mindestens einen Druckkörper 4 wirkende Druckkraft bereitzustellen.In addition, the adjusting device 1 according to the invention has a pressure device 5 assigned to the at least one pressure body 4 in order to provide a pressure force acting on the at least one pressure body 4, at least if necessary.

Die erfindungsgemäße Verstellvorrichtung 1, welche exemplarisch in der Prinzipdarstellung gemäß FIG. 1a gezeigt ist, zeichnet sich insbesondere dadurch aus, dass die Druckeinrichtung 5 über einen Hebelmechanismus 6 mit dem mindestens einem Druckkörper 4 wirkverbunden ist.The adjusting device 1 according to the invention, which is shown as an example in the schematic diagram according to FIG. 1a is shown, is characterized in particular by the fact that the printing device 5 is operatively connected to the at least one pressure body 4 via a lever mechanism 6.

Im Einzelnen und wie in FIG. 1a schematisch dargestellt, weist der Hebelmechanismus 6 mindestens einen Hebelarm 6a, 6b auf, wobei ein erster Endbereich des Hebelarms 6a, 6b in einer horizontalen Ebene verschwenkbar mit der Druckeinrichtung 5 verbunden ist, und wobei ein dem ersten Endbereich gegenüberliegender zweiter Endbereich des Hebelarms 6a, 6b in einer horizontalen Ebene verschwenkbar mit der Stützstruktur 2 des spurgeführten Fahrzeugs verbunden ist.In detail and as in FIG. 1a Shown schematically, the lever mechanism 6 has at least one lever arm 6a, 6b, with a first end region of the lever arm 6a, 6b being pivotally connected to the printing device 5 in a horizontal plane, and with a second end region of the lever arm 6a, 6b opposite the first end region is pivotally connected in a horizontal plane to the support structure 2 of the track-guided vehicle.

Bei dieser Stützstruktur 2 handelt es sich beispielsweise um einen Lagerbock oder um eine Grundplatte der Kupplung, zu welcher die Kupplungsstange gehört.This support structure 2 is, for example, a bearing block or a base plate of the coupling, to which the coupling rod belongs.

Der mindestens eine Druckkörper 4 ist dabei in einem Bereich zwischen dem ersten und dem zweiten Endbereich des Hebelarms 6a, 6b angeordnet, wobei eine Position des mindestens einen Druckkörpers 4 zwischen dem ersten und dem zweiten Endbereich des Hebelarms 6a, 6b vorzugsweise einstellbar ist.The at least one pressure body 4 is arranged in a region between the first and the second end region of the lever arm 6a, 6b, with a position of the at least one pressure body 4 between the first and the second end region of the lever arm 6a, 6b being preferably adjustable.

Im Einzelnen ist bei der in FIG. 1a schematisch dargestellten Ausführungsform der erfindungsgemäßen Verstellvorrichtung 1 vorgesehen, dass symmetrisch zur Längsachse der Kupplungsstange insgesamt zwei Druckkörper 4 vorgesehen sind, welche jeweils ausgebildet sind, um zumindest bedarfsweise ein auf die Führung 3 wirkendes Drehmoment zu erzeugen.In detail, the in FIG. 1a In the schematically illustrated embodiment of the adjusting device 1 according to the invention, a total of two pressure bodies 4 are provided symmetrically to the longitudinal axis of the coupling rod, each of which is designed to generate a torque acting on the guide 3, at least if necessary.

Als Druckkörper 4 kommen beispielsweise Druckzylinder oder ähnliche Komponenten in Frage.Examples of possible pressure bodies 4 include pressure cylinders or similar components.

Bei der in FIG. 1a schematisch dargestellten exemplarischen Ausführungsform der erfindungsgemäßen Verstellvorrichtung 1 sind symmetrisch zur Längsachse der Kupplungsstange insgesamt zwei Druckkörper 4 vorgesehen, welche jeweils ausgebildet sind, bedarfsweise ein auf die Führung 3 wirkendes Druckmoment zu erzeugen.At the in FIG. 1a In the schematically illustrated exemplary embodiment of the adjusting device 1 according to the invention, a total of two pressure bodies 4 are provided symmetrically to the longitudinal axis of the coupling rod, each of which are designed, if necessary, to generate a pressure torque acting on the guide 3.

Die Druckeinrichtung 5 weist vorzugsweise einen linear wirkenden Aktuator auf, welcher ausgebildet ist, bedarfsweise eine zumindest teilweise quer zur Längsachse der Kupplungsstange wirkende Druckkraft zu generieren. Der Aktuator ist vorzugsweise als Pneumatik- oder Hydraulikzylinder ausgeführt.The pressure device 5 preferably has a linearly acting actuator, which is designed, if necessary, to generate a pressure force that acts at least partially transversely to the longitudinal axis of the coupling rod. The actuator is preferably designed as a pneumatic or hydraulic cylinder.

In einer alternativen Ausführungsform kann die Druckeinrichtung 5 auch eine entsprechende Druckfeder aufweisen (vgl. FIG. 1b).In an alternative embodiment, the printing device 5 can also have a corresponding compression spring (cf. FIG. 1b ).

Im Einzelnen ist es bevorzugt, dass der Hebelmechanismus 6 zwei parallel zueinander verlaufende Hebelarme 6a, 6b aufweist, wobei die Druckeinrichtung 5 zwischen den beiden ersten Endbereichen der beiden Hebelarme 6a, 6b angeordnet, insbesondere eingespannt ist. Wie in FIG. 1a schematisch angedeutet, bietet es sich in diesem Zusammenhang an, dass die Druckeinrichtung 5 freischwebend zwischen den beiden ersten Endbereichen der beiden Hebelarme 6a, 6b angeordnet, insbesondere eingespannt ist.In detail, it is preferred that the lever mechanism 6 has two lever arms 6a, 6b that run parallel to one another, with the pressure device 5 being arranged, in particular clamped, between the two first end regions of the two lever arms 6a, 6b. As in FIG. 1a schematically indicated, it is advisable in this context that the printing device 5 is arranged, in particular clamped, in a freely floating manner between the two first end regions of the two lever arms 6a, 6b.

Wie es ebenfalls der Prinzipdarstellung in FIG. 1a entnommen werden kann, ist gemäß Ausführungsformen der erfindungsgemäßen Verstellvorrichtung 1 vorgesehen, dass die Führung 3, welche mit der in FIG. 1a nicht explizit dargestellten Kupplungsstange wirkverbunden ist, einen dem mindestens einem Druckkörper 4 zugeordneten Bereich 7 aufweist, welcher eine derart zu dem Druckkörper 4 komplementär ausgeführte Formgebung und/oder Kontur aufweist, dass ein zum Verstellen der Kupplungsstange erforderliches Drehmoment auf die Führung 3 wirkt, wenn der Druckkörper 4 gedrückt wird.As is also the schematic diagram in FIG. 1a can be removed, it is provided according to embodiments of the adjusting device 1 according to the invention that the guide 3, which is connected to the in FIG. 1a Coupling rod, not explicitly shown, is operatively connected, has an area 7 assigned to at least one pressure body 4, which has a shape and / or contour that is complementary to the pressure body 4 in such a way that a torque required to adjust the coupling rod acts on the guide 3 when the Pressure body 4 is pressed.

Insbesondere ist es in diesem Zusammenhang denkbar, dass der Druckkörper 4 und der dem Druckkörper 4 zugeordnete Bereich 7 der Führung 3 ausgeführt sind, zumindest bereichsweise eine formschlüssige Paarung auszubilden, wenn der Druckkörper 4 in den ihm zugeordneten Bereich 7 gedrückt wird.In particular, it is conceivable in this context that the pressure body 4 and the area 7 of the guide 3 assigned to the pressure body 4 are designed to form a positive pairing, at least in some areas, when the pressure body 4 is pressed into the area 7 assigned to it.

Wie es ebenfalls der Prinzipdarstellung in FIG. 1a entnommen werden kann, ist es grundsätzlich denkbar, dass die Führung 3 zumindest bereichsweise als Kurvenscheibe ausgebildet ist, die um einen vertikal verlaufenden Schwenkbolzen relativ zu der Stützstruktur 2 gelagert und mit der Kupplungsstange drehsynchron gekoppelt ist.As is also the schematic diagram in FIG. 1a can be removed, it is fundamentally conceivable that the guide 3 is designed at least in some areas as a cam, which is mounted around a vertically extending pivot pin relative to the support structure 2 and is coupled in a rotationally synchronous manner to the coupling rod.

In FIG. 1b ist schematisch eine Prinzipskizze einer zweiten exemplarischen Ausführungsform der erfindungsgemäßen Vorrichtung 1 zum horizontalen Verstellen einer relativ zu einer Stützstruktur 2 verschwenkbaren Kupplungsstange in eine vorab festgelegte oder festlegbare Stellung, insbesondere Mittenstellung, gezeigt.In FIG. 1b A schematic diagram of a second exemplary embodiment of the device 1 according to the invention is shown schematically for horizontally adjusting a coupling rod which can be pivoted relative to a support structure 2 into a predetermined or definable position, in particular a central position.

Die zweite exemplarische Ausführungsform gemäß FIG. 1b entspricht in struktureller und funktioneller Hinsicht der ersten Ausführungsform gemäß FIG. 1a, wobei allerdings bei der zweiten Ausführungsform die Druckeinrichtung 5 eine Druckfeder als linear wirkender Aktuator aufweist, welcher ausgebildet ist, bedarfsweise eine zumindest teilweise quer zur Längsachse der Kupplungsstange wirkende Druckkraft zu generieren.The second exemplary embodiment according to FIG. 1b Corresponds structurally and functionally to the first embodiment FIG. 1a , although in the second embodiment the pressure device 5 has a compression spring as a linear actuator, which is designed, if necessary, to generate a pressure force acting at least partially transversely to the longitudinal axis of the coupling rod.

Die Erfindung ist nicht auf die schematisch in FIG. 1a und FIG. 1b gezeigten exemplarischen Ausführungsformen beschränkt, sondern ergibt sich aus einer Zusammenschau sämtlicher hierin offenbarter Merkmale.The invention is not limited to the schematic in FIG. 1a and FIG. 1b shown exemplary embodiments, but results from a synopsis of all features disclosed herein.

Die FIG. 2 zeigt eine konstruktive Ausführung einer Ausführungsform gemäß FIG. 1a. Der Hebelmechanismus 6 weist zwei Hebelarme 6a und 6b auf, welche vorzugsweise in einer horizontalen Ebene E angeordnet sind. Die Hebelarme 6a und 6b sind im dargestellten Fall spiegelbildlich bezüglich einer senkrecht zur horizontalen Ebene E angeordneten Ebene angeordnet. Diese senkrechte Ebene kann in Einbaulage durch die Kupplungslängsachse und eine Senkrechte zu dieser beschrieben werden. Jeder der einzelnen Hebelarme 6a, 6b ist in einem zweiten Endbereich mit einer hier nicht dargestellten Stützstruktur verbunden. Die Verbindung erfolgt gelenkig, insbesondere drehbar um eine senkrecht zur horizontalen Ebene E angeordnete Achse. Dies wird beispielsweise über ein Drehgelenk 8 realisiert. Die Hebelarme 6a, 6b wirken jeweils auf die Druckkörper 4, welche wiederum mit der mit der Kupplungsstange wirkverbundenen Führung 3 derart zusammenwirken, dass auf diese ein zum Verstellen der Kupplungsstange erforderliches Drehmoment erzeugt wird. Der Einwirkbereich der Hebelarme 6a, 6b auf die Druckkörper 4 ist im dargestellten Fall in Längsrichtung der Vorrichtung betrachtet zwischen erstem und zweitem Endbereich angeordnet. Die Druckeinrichtung 5 ist zwischen den beiden, dem zweiten Endbereich gegenüberliegenden ersten Endbereichen der Hebelarme 6a, 6b angeordnet und wenigstens mittelbar, vorzugsweise direkt freitragend und gelenkig mit diesen verbunden. Im dargestellten Fall ist die Druckeinrichtung 5 als hydraulischer Aktuator, insbesondere Zylinder-/Kolbeneinheit ausgebildet, welche die erforderliche Kraft am Druckkörper über Zugkraft auf beide Hebelarme einstellt. Die Verbindung zwischen dem Kolben einerseits und dem diesen zugeordneten Hebelarm und dem Zylinder und dem diesen zugeordneten Hebelarm andererseits erfolgt hier jeweils über ein Drehgelenk 9, d.h. gelenkig um eine senkrecht zur Ebene E ausgerichtete Achse.The FIG. 2 shows a structural design of an embodiment according to FIG. 1a . The lever mechanism 6 has two lever arms 6a and 6b, which are preferably arranged in a horizontal plane E. In the case shown, the lever arms 6a and 6b are arranged in mirror image with respect to a plane arranged perpendicular to the horizontal plane E. In the installed position, this vertical plane can be described by the longitudinal axis of the coupling and a perpendicular to it. Each of the individual lever arms 6a, 6b is connected in a second end region to a support structure, not shown here. The connection is articulated, in particular rotatable about an axis arranged perpendicular to the horizontal plane E. This is realized, for example, via a swivel joint 8. The lever arms 6a, 6b each act on the pressure bodies 4, which in turn interact with the guide 3, which is operatively connected to the coupling rod, in such a way that a torque required for adjusting the coupling rod is generated. The area of action of the lever arms 6a, 6b on the pressure bodies 4 is arranged in the case shown in the longitudinal direction of the device between the first and second end areas. The printing device 5 is arranged between the two first end regions of the lever arms 6a, 6b opposite the second end region and is connected to them at least indirectly, preferably directly, in a cantilevered and articulated manner. In the case shown, the printing device 5 is designed as a hydraulic actuator, in particular a cylinder/piston unit, which generates the required force on the pressure body adjusted via tensile force on both lever arms. The connection between the piston on the one hand and the lever arm assigned to it and the cylinder and the lever arm assigned to it on the other hand takes place here via a swivel joint 9, ie articulated about an axis aligned perpendicular to the plane E.

Die geometrische Ausführung der Hebelarme 6a, 6b selbst kann durch eine gerade Linie oder eine gekrümmte Ausführung beschrieben werden. Entscheidend sind die Erstreckung in Längsrichtung und die in dieser Richtung erfolgende versetzte Anordnung von Einwirkbereich und Anbindungsbereich für die Druckeinrichtung und das Erzeugen des erforderlichen Drehmomentes an der Führung über Formschluss zwischen Führung und Druckkörper bzw. Führung und Hebelarm.The geometric design of the lever arms 6a, 6b themselves can be described by a straight line or a curved design. What is crucial is the extension in the longitudinal direction and the offset arrangement of the action area and connection area for the printing device in this direction and the generation of the required torque on the guide via positive connection between the guide and pressure body or guide and lever arm.
