Description

Die Erfindung betrifft eine Vorrichtung zum Verschwenken einer oder mehrerer Bugklappen eines spurgeführten Fahrzeuges, insbesondere Schienenfahrzeuges.The invention relates to a device for pivoting one or more nose flaps of a track-guided vehicle, in particular rail vehicle.

Eine Vorrichtung mit den im Oberbegriff von Anspruch 1 definierten Merkmalen ist aus der WO 2007/073273 bekannt.A device having the features defined in the preamble of claim 1 is known from WO 2007/073273 known.

Aus der Schienenfahrzeugtechnik ist es bekannt, die Stirnseite eines spurgeführten Fahrzeuges mit einer Schutzverkleidung zu versehen, um die an der Fahrzeugstirnseite vorgesehene Kupplung, und insbesondere den Kupplungskopf vor Witterungseinflüssen wie Schnee, Vereisung, Feuchtigkeit und Schmutz zu schützen, wenn die Kupplung nicht zum Einsatz kommt und in ihrem entkuppelten Zustand vorliegt. Hierzu kommen sogenannte Frontmodule zum Einsatz, welche an der Fahrzeugstirnseite montiert sind. Ein Frontmodul weist in der Regel mindestens eine Bugklappe auf, welche relativ zu dem Fahrzeuguntergestell und der an der Fahrzeugstirnseite vorgesehenen Kupplung verschwenkbar ist, um bei Bedarf den Kupplungsschacht freizulegen.From rail vehicle technology, it is known to provide the front side of a track-guided vehicle with a protective cover to protect the provided on the vehicle front side coupling, and in particular the coupling head from the weather, such as snow, icing, moisture and dirt when the clutch is not used and in its uncoupled state. For this purpose, so-called front modules are used, which are mounted on the vehicle front side. A front module usually has at least one nose flap, which is pivotable relative to the vehicle underframe and provided on the vehicle front side coupling to expose the coupling shaft when needed.

Unter dem Begriff "Bugklappe wird hierin die Verkleidung des Kupplungsschachtes verstanden, welche in ihrem geschlossenen Zustand den Kupplungsschacht frontseitig abdeckt, um einerseits die Kupplungsbauteile vor Witterungseinflüssen zu schützen und andererseits aerodynamisch nachteilige Frontpartien zu vermeiden, was insbesondere bei stromlinienförmigen Triebzügen wie Hochgeschwindigkeitszügen wichtig ist.The term "nose flap is here understood the cladding of the coupling shaft, which covers the coupling shaft in the front in its closed state, on the one hand to protect the coupling components from the weather and on the other to avoid aerodynamically disadvantageous front parts, which is particularly important for streamlined trainsets such as high-speed trains.

Zum Verschwenken der Bugklappe relativ zu dem Fahrzeuguntergestell kommt in der Regel eine Bugklappen-Kinematik zum Einsatz, welche mindestens eine Betätigungseinrichtung aufweist und dazu dient, bei Bedarf den Kupplungsschacht und somit den Kupplungskopf freizulegen. Dies ist insbesondere dann erforderlich, um das Fahrzeug in einen kuppelbereiten Zustand zu überführen, oder um beispielsweise aus Wartungsgründen einen Zugang zu dem Kupplungsschacht und den Kupplungsbauteilen zu ermöglichen.For pivoting the nose flap relative to the vehicle undercarriage is usually a Bugklappen kinematics used, which has at least one actuator and serves to expose the coupling shaft and thus the coupling head when needed. This is particularly necessary in order to bring the vehicle in a dome-ready state, or to allow for example for maintenance access to the coupling shaft and the coupling components.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Verschwenken einer Bugklappe anzugeben, mit welcher die Bugklappe von einer ersten geschlossenen Position in eine zweite geöffnete Position überführbar ist, wobei sich die Vorrichtung dadurch auszeichnet, dass die zum Verschwenken der Bugklappe zum Einsatz kommende Bugklappen-Kinematik einerseits möglichst einfach aufgebaut ist, andererseits aber dennoch zuverlässig funktioniert.The object of the invention is to provide a device for pivoting a nose flap, with which the nose flap can be moved from a first closed position to a second open position, wherein the device is characterized in that the pivoting of the nose flap coming to use the bow flap kinematics on the one hand as simple as possible, on the other hand, but still works reliably.

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des unabhängigen Patentanspruches 1 gelöst.This object is achieved by the subject matter of the independent claim 1.

Demnach wird eine Vorrichtung zum Verschwenken einer oder mehrerer Bugklappen eines spurgeführten Fahrzeuges, insbesondere Schienenfahrzeuges vorgeschlagen, wobei die Vorrichtung mindestens einen mit dem Fahrzeuguntergestell verbunden oder verbindbaren Tragrahmen und mindestens eine mit dem mindestens einem Tragrahmen einerseits und der zur verschwenkenden Bugklappe andererseits verbundene Betätigungseinrichtung zum Verschwenken der Bugklappe relativ zu dem Tragrahmen von einem geschlossenen Zustand in einen geöffneten Zustand und umgekehrt aufweist, wobei die Betätigungseinrichtung mindestens einen Hubspindelantrieb aufweist.An apparatus for pivoting one or more nose flaps of a track-guided vehicle, in particular rail vehicle is proposed, wherein the device at least one connected to the vehicle undercarriage or connectable support frame and at least one with the at least one support frame on the one hand and the pivoting bow door on the other hand connected actuator for pivoting the Bug flap relative to the support frame from a closed state to an open state and vice versa, wherein the actuating device has at least one Hubspindelantrieb.

Durch das Vorsehen eines Hubspindelanstriebs zum Bewirken der Schwenkbewegung der Bugklappe relativ zu dem Tragrahmen wird eine besonders einfach zu realisierende aber dennoch effektive Bugklappen-Kinematik angegeben. Diese Lösung zeichnet sich insbesondere durch den geringen Wartungsaufwand für die Bugklappen-Kinematik aus. Darüber hinaus ist die Vorrichtung auch unter rauen Umgebungsbedingungen stets einwandfrei einsetzbar, da die gesamte Antriebsmechanik in einem Gehäuse gekapselt ausgeführt werden kann. Hubspindelantriebe weisen einen einfachen und wartungsarmen Aufbau auf, wobei zur Realisierung der erfindungsgemäßen Lösung insbesondere auch auf bereits existierende Technologien zurück gegriffen werden kann. Selbst bei einem Ausfall des Hubspindelantriebs bleibt die mit dem Hubspindelantrieb zu verschwenkende Bugklappe stets in ihrer letzten Verschwenkposition, da der Hubspindelantrieb selbsthemmend ist.By providing a Hubspindelanstriebs for effecting the pivotal movement of the nose flap relative to the support frame a particularly easy to implement but effective Bugklappen kinematics is specified. This solution is characterized in particular by the low maintenance required for the Bugklappen kinematics. In addition, the device is always perfectly usable even under harsh environmental conditions, since the entire drive mechanism can be executed encapsulated in a housing. Hubspindelantriebe have a simple and low-maintenance construction, which used to implement the inventive solution in particular also on existing technologies can be. Even with a failure of the Hubspindelantriebs remains to be pivoted with the Hubspindelantrieb Bugklappe always in its last pivoting position, since the Hubspindelantrieb is self-locking.

Vorteilhafte Weiterbildungen der erfindungsgemäßen Lösung sind in den Unteransprüchen angegeben.Advantageous developments of the solution according to the invention are specified in the subclaims.

So ist es im Hinblick auf die Betätigungseinrichtung denkbar, dass diese einen elektrisch, pneumatisch oder hydraulisch betätigbaren Hubspindelantrieb aufweist. Insofern kann zum Betätigen des Hubspindelantriebes auf in der Regel bereits existierende Strom-, Pneumatik- oder Hydraulikleitungen zurückgegriffen werden. Es ist dabei besonders bevorzugt, die Betätigungseinrichtung mit einem vorzugsweise elektrischen Verstellmotor zum Betätigen des Hubspindelantriebes auszubilden.Thus, with regard to the actuating device, it is conceivable that it has an electrically, pneumatically or hydraulically actuatable lifting spindle drive. In this respect, can be used to actuate the Hubspindelantriebes usually already existing power, pneumatic or hydraulic lines. It is particularly preferred to form the actuating device with a preferably electric adjusting motor for actuating the Hubspindelantriebes.

Grundsätzlich ist es von Vorteil, wenn der Hubspindelantrieb auch manuell, insbesondere mit Hilfe einer Handkurbel, betätigbar ist. Somit lässt sich die Bugklappe auch dann verschwenken, wenn beispielsweise aufgrund einer Störung eine automatische Ansteuerung des Hubspindelantriebs nicht gegeben ist. Hierbei ist es insbesondere von Vorteil, die Betätigungseinrichtung grundsätzlich mit einem manuell betätigbaren Hubspindelantrieb auszurüsten, wobei dieser Hubspindelantrieb gegebenenfalls nachträglich derart umgerüstet werden kann, dass dieser auch pneumatisch, hydraulisch und/oder mit Hilfe eines elektrischen Verstellmotors betätigbar ist.In principle, it is advantageous if the Hubspindelantrieb also manually, in particular by means of a hand crank, can be actuated. Thus, the bow door can also be pivoted if, for example due to a fault, an automatic control of the Hubspindelantriebs is not given. It is particularly advantageous to basically equip the actuator with a manually actuated Hubspindelantrieb, this Hubspindelantrieb may optionally be retrofitted so that it can also be operated pneumatically, hydraulically and / or by means of an electric variable motor.

In einer möglichen Realisierung des Hubspindelantriebs ist vorgesehen, dass dieser ein Gehäuse und eine in dem Gehäuse vorzugsweise über eine Spindelmutter gelagerte Hubspindel aufweist, wobei die Hubspindel bei Betätigung des Hubspindelantriebs relativ zu dem Gehäuse bedarfsweise aus- und einfahrbar ist. Selbstverständlich kommen hier aber auch andere Ausführungsformen für den Hubspindelantrieb in Frage. Insbesondere ist das Vorsehen einer Spindelmutter, über welche die Hubspindel in dem Gehäuse des Hubspindelantriebs gelagert ist, nicht zwingend erforderlich.In a possible realization of the Hubspindelantriebs is provided that this has a housing and a preferably mounted in the housing via a spindle nut lifting spindle, wherein the lifting spindle when operating the Hubspindelantriebs relative to the housing as needed and retractable. Of course, other embodiments come here for the Hubspindelantrieb in question. In particular, the provision of a spindle nut, via which the lifting spindle is mounted in the housing of the Hubspindelantriebs, not mandatory.

In einer bevorzugten Weiterbildung der zuletzt genannten Ausführungsform, bei welcher der Hubspindelantrieb ein Gehäuse sowie eine relativ zu dem Gehäuse aus- bzw. einfahrbare Hubspindel aufweist, ist vorgesehen, dass das Gehäuse des Hubspindelantriebs vorzugsweise in der vertikalen oder horizontalen Ebene verschwenkbar mit dem mindestens einen Tragrahmen verbunden ist. Hierbei ist es ferner von Vorteil, wenn die Hubspindel des Hubspindelantriebs an ein Hebelelement angelenkt ist, welches vorzugsweise über ein Lager in der vertikalen oder horizontalen Ebene verschwenkbar an dem mindestens einen Tragrahmen angelenkt ist. Das Hebelelement ist in einer weiteren Ausführungsform dabei mit der der Hubspindelantrieb zugeordneten Bugklappe derart verbunden, dass bei Betätigung des Hubspindelantriebs die Bugklappe entsprechend verschwenkt wird.In a preferred development of the latter embodiment, in which the Hubspindelantrieb has a housing and a relative to the housing off or retractable lifting spindle, it is provided that the housing of the Hubspindelantriebs preferably in the vertical or horizontal plane pivotally with the at least one support frame connected is. It is also advantageous if the lifting spindle of the Hubspindelantriebs articulated to a lever element is, which is preferably articulated via a bearing in the vertical or horizontal plane pivotally mounted on the at least one support frame. In a further embodiment, the lever element is in this case connected to the nose flap associated with the lifting spindle drive in such a manner that, when the lifting spindle drive is actuated, the nose flap is correspondingly pivoted.

In einer besonders bevorzugten Realisierung der erfindungsgemäßen Lösung ist vorgesehen, dass zum Verschwenken der Bugklappe eine Betätigungseinrichtung vorgesehen ist, wobei diese Betätigungseinrichtung einen ersten Hubspindelantrieb mit mindestens einem der zuvor genannten Merkmale sowie einen zweiten Hubspindelantrieb vorzugsweise der gleichen Bauart aufweist, wobei der erste und zweite Hubspindelantrieb gemeinsam der Bugklappe zugeordnet sind, um die Bugklappe bedarfsweise verschwenken zu können.In a particularly preferred realization of the solution according to the invention, it is provided that an actuating device is provided for pivoting the nose flap, said actuating device having a first Hubspindelantrieb with at least one of the aforementioned features and a second Hubspindelantrieb preferably of the same type, wherein the first and second Hubspindelantrieb are jointly assigned to the bow door to pivot the bow door as needed.

Bei dieser Weiterbildung ist es insbesondere von Vorteil, ein Synchronisationselement beispielsweise in Gestalt eines stabförmigen Elements vorzusehen, um die Bewegung des ersten und zweiten Hubspindelantriebs bedarfsweise synchronisieren zu können. Durch das vorsehen eines derartigen Synchronisationselements ist es möglich, für die beiden über das Synchronisationselement miteinander gekoppelten Hubspindelantrieb eine gemeinsamen Antrieb, beispielsweise elektrischen Verstellmotor, vorzusehen.In this development, it is particularly advantageous to provide a synchronization element, for example in the form of a rod-shaped element in order to be able to synchronize the movement of the first and second Hubspindelantriebs if necessary. By providing such a synchronization element, it is possible for the two coupled via the synchronization element Hubspindelantrieb a common drive, for example, electric adjusting motor to provide.

In einer denkbaren Realisierung der zuletzt genannten Ausführungsform ist vorgesehen, dass der erste und zweite Hubspindelantrieb jeweils eine Spindelmutter und eine über die Spindelmutter gelagerte Hubspindel aufweisen, wobei das Synchronisationselement einerseits mit dem ersten Hubspindelantriebs und andererseits mit dem zweiten Hubspindelantriebs verbunden ist.In a conceivable implementation of the latter embodiment, it is provided that the first and second Hubspindelantrieb each have a spindle nut and a spindle mounted on the spindle spindle, wherein the synchronization element is connected on the one hand to the first Hubspindelantriebs and on the other hand to the second Hubspindelantriebs.

Die erfindungsgemäße Lösung ist nicht auf eine Vorrichtung beschränkt, welche lediglich eine einzige Bugklappe relativ zu dem Tragrahmen verschwenken kann. So ist es beispielsweise denkbar, die erfindungsgemäße Lösung auch zum Verschwenken einer zweigeteilten Bugklappe einzusetzen. In diesem Zusammenhang ist es von Vorteil, wenn eine erste Betätigungseinrichtung zum bedarfsweisen Verschwenken einer ersten Bugklappe und eine zweite Betätigungseinrichtung zum bedarfsweisen Verschwenken einer zweiten Bugklappe vorgesehen sind.The solution according to the invention is not limited to a device which can pivot only a single nose flap relative to the support frame. Thus, it is conceivable, for example, to use the solution according to the invention for pivoting a two-part nose flap. In this connection, it is advantageous if a first actuating device for pivoting a first nose flap as required and a second actuating device for pivoting a second nose flap as required are provided.

In einer besonders bevorzugten Realisierung der zuletzt genannten Lösung ist vorgesehen, dass die erste Bugklappe mit Hilfe der ersten Betätigungseinrichtung relativ zu dem Tragrahmen in einer vertikalen Ebene nach oben verschwenkbar ausgeführt ist, wobei die zweite Bugklappe mit Hilfe der zweiten Betätigungseinrichtung relativ zu dem Tragrahmen in einer vertikalen Ebene nach unten verschwenkbar ausgeführt ist. Selbstverständlich ist es aber auch denkbar, die beiden Bugklappen jeweils in einer horizontalen Ebene verschwenkbar auszuführen.In a particularly preferred realization of the latter solution, it is provided that the first nose flap with the aid of the first actuating device relative to the support frame is designed to pivot in a vertical plane upwards, wherein the second nose flap with the aid of the second actuator relative to the support frame in a vertical plane is designed to pivot downwards. Of course, it is also conceivable to perform the two bow flaps each pivotable in a horizontal plane.

Weitere Vorteile, Aspekte und Merkmale der erfindungsgemäßen Lösung ergeben sich anhand der nachfolgenden Beschreibung eines Ausführungsbeispiels, welches in den beiliegenden Zeichnungen dargestellt ist.Further advantages, aspects and features of the solution according to the invention will become apparent from the following description of an embodiment which is illustrated in the accompanying drawings.
