Description

Die Erfindung betrifft ein Fahrzeug, insbesondere ein Brückenverlegefahrzeug, mit einer Abstützvorrichtung mit einem über eine Hubvorrichtung zwischen einer Abstützstellung und einer Fahrstellung hin- und her bewegbaren Stützschild, wobei die Hubvorrichtung mindestens ein längenveränderbares Hub-element aufweist. Die Erfindung betrifft ferner eine Abstützvorrichtung zur Anordnung an Fahrzeuge, insbesondere zur Anordnung an Brückenverlegefahrzeugen, mit einem über eine Hubvorrichtung zwischen einer Abstützstellung und einer Fahrstellung hin- und her bewegbaren Abstützschild, wobei die Hubvorrichtung mindestens ein längenveränderbares Hubelement aufweist.The invention relates to a vehicle, in particular a bridge laying vehicle, with a supporting device with a lifting device which can be moved back and forth between a supporting position and a driving position, wherein the lifting device has at least one length-adjustable lifting element. The invention further relates to a supporting device for arrangement on vehicles, in particular for arrangement on bridge laying vehicles, with a lifting device which can be moved back and forth between a supporting position and a driving position, wherein the lifting device has at least one length-adjustable lifting element.

Bei vielerlei Arten von Nutzfahrzeugen ist es aufgrund sich im Betrieb verändernder, in bestimmten Situationen ungünstiger Schwerpunktverhältnisse erforderlich, eine Abstützvorrichtung vorzusehen, über welche sich das Fahrzeug zusätzlich zu seiner eigentlichen Standfläche gegenüber dem Boden abstützen kann.In many types of commercial vehicles, it is due to changing in operation, unfavorable in certain situations balance conditions required to provide a support device through which the vehicle can be supported in addition to its actual footprint against the ground.

Beispielsweise ergeben sich bei Brückenverlegefahrzeugen, die eine transportable Brücke auf ihrer Oberseite aufnehmen und an einem Einsatzort über entsprechende Verlegeeinrichtungen verlegen, insbesondere während des Verlegevorgangs ungünstige Schwerpunktverhältnisse. Beim Verlegen derartiger Brücken wandert der sich aus dem Gewicht des Fahrzeugs und der auf diesem angeordneten Brückenelemente ergebende Gesamtschwerpunkt teilweise bis über die Kontur des Fahrzeugs hinaus, weshalb in solchen Situationen die Gefahr besteht, dass der Stand des Fahrzeugs instabil wird und dieses im schlimmsten Fall sogar zu kippen droht.For example, in bridge laying vehicles, which receive a transportable bridge on their upper side and lay at a place of use via corresponding laying devices, unfavorable center of gravity relationships arise, in particular during the laying process. When installing such bridges, the total center of gravity resulting from the weight of the vehicle and the bridge elements arranged thereon partially migrates beyond the contour of the vehicle, so that in such situations there is a risk of the vehicle becoming unstable and, in the worst case, even becoming unstable threatens to tip over.

Um derartige Probleme zu vermeiden, sind Abstützvorrichtungen bekannt, die in solchen Situationen einen zusätzlichen Abstützpunkt neben der Kontur des Fahrzeugs bereitstellen. Die Abstützvorrichtungen verfügen über eine Hubvorrichtung, über welche sich ein Stützschild bei Bedarf von einer höher liegenden Fahrstellung in eine Abstützstellung bewegen lässt, in welcher das Stützschild am Untergrund anliegt und einen zusätzlichen Abstützpunkt für das Fahrzeug bildet, welcher selbst bei ungünstigen Schwerpunktverhältnissen die Gefahr eines Kippens des Fahrzeugs deutlich reduziert.To avoid such problems, support devices are known which provide an additional support point next to the contour of the vehicle in such situations. The support devices have a lifting device, via which a support plate can move from a higher driving position to a support position when needed, in which the support plate rests against the ground and forms an additional support point for the vehicle, which even with unfavorable center of gravity the risk of tipping the vehicle significantly reduced.

Die Hubvorrichtungen zum Anheben bzw. Absenken des Stützschilds verfügen über zumindest ein längenveränderbares Hubelement, beispielsweise in Form eines Hydraulikzylinders, welches mit dem Stützschild gekoppelt ist.The lifting devices for raising or lowering the support plate have at least one length-variable lifting element, for example in the form of a hydraulic cylinder, which is coupled to the support plate.

Bei militärischen Brückenverlegefahrzeugen ist oftmals vorgesehen, dass ein Ende des Hydraulikzylinders schwenkbeweglich an einem mit dem Stützschild verbundenen Längslenker angebunden ist, wobei das andere Ende des Hydraulikzylinders um eine quer zur Fahrzeuglängsrichtung verlaufende Schwenkachse schwenkbeweglich an einem fahrzeugfesten Anlenkpunkt angelenkt ist. Bei Betätigung des Hydraulikzylinders beginnt der Hydraulikzylinder und mit diesem der Längslenker in einer Fahrzeuglängsebene zu schwenken, so dass das am freien Ende des Längslenkers angeordnete Stützschild entlang einer Kreisbahn zu verschwenken beginnt.In military bridge laying vehicles is often provided that one end of the hydraulic cylinder is pivotally connected to a connected to the support plate trailing arm, the other end of the hydraulic cylinder is pivotable about a transverse to the vehicle longitudinal direction pivot axis pivotally mounted on a vehicle-fixed articulation point. Upon actuation of the hydraulic cylinder, the hydraulic cylinder begins to pivot and with this the trailing arm in a vehicle longitudinal plane, so that the arranged at the free end of the trailing arm support plate begins to pivot along a circular path.

Ein Fahrzeug mit einer Abstutzvorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus DE 2 932 135 bekannt.A vehicle with a Abstutzvorrichtung with the features of the preamble of claim 1 is made DE 2 932 135 known.

Bei dieser Art von Abstützvorrichtung hat es sich als nachteilig erwiesen, dass das Stützschild entlang einer Kreisbahn verschwenkt, was insbesondere in der vergleichsweise hoch liegenden Fahrstellung zu einer Sichteinschränkung des Fahrzeugführers führen kann.In this type of supporting device, it has proven to be disadvantageous that the support plate pivots along a circular path, which can lead to a visual restriction of the driver especially in the relatively high driving position.

Aufgabe der Erfindung ist es, ein Fahrzeug bzw. eine Abstützvorrichtung der eingangs genannten Art anzugeben, die in der Fahrstellung eine kompakte, die Sicht des Fahrzeugführers nicht einschränkende Stellung einnimmt.The object of the invention is to provide a vehicle or a supporting device of the type mentioned above, which occupies a compact, the view of the driver not restricting position in the driving position.

Diese Aufgabe wird bei einem Fahrzeug der eingangs genannten Art dadurch gelöst, dass das Hubelement schwenkbeweglich um eine sich in Fahrzeuglängsrichtung erstreckende Achse angeordnet ist.This object is achieved in a vehicle of the type mentioned above in that the lifting element is arranged to pivot about an axis extending in the vehicle longitudinal axis.

Bei einer Abstützvorrichtung der eingangs genannten Art wird die Aufgabe dadurch gelöst, dass das Hubelement schwenkbeweglich um eine sich in Fahrzeuglängsrichtung erstreckende Achse anordbar ist.In a supporting device of the type mentioned, the object is achieved in that the lifting element can be arranged to pivot about an axis extending in the vehicle longitudinal axis.

Die schwenkbewegliche Anordnung des Hubelements an einer sich in Fahrzeuglängsrichtung erstreckenden Achse erlaubt eine raumsparende Bewegung des Stützschilds zwischen der Fahrstellung und der Abstützstellung. Das Stützschild schwenkt nicht vom Fahrzeug weg, sondern bewegt sich translatorisch in einer Ebene parallel zur Außenkontur des Fahrzeugs, wodurch die Abstützvorrichtung in der Fahrstellung eine kompakte Stellung einnehmen kann.The pivotable arrangement of the lifting element on an axis extending in the vehicle longitudinal direction allows a space-saving movement of the support plate between the driving position and the support position. The support plate does not pivot away from the vehicle, but moves translationally in a plane parallel to the outer contour of the vehicle, whereby the support device can assume a compact position in the driving position.

Gemäß der Erfindung wird das Hubelement zwischen einer fahrzeugfesten Aufnahme und dem Stützschild angeordnet. Das Hubelement kann dabei direkt an die Aufnahme und/oder das Stützschild angebunden sein. Auch ist es denkbar, dass das Hubelement indirekt an die Aufnahme und/oder das Stützschild angebunden ist, beispielsweise über ein Zwischenelement wie eine Strebe oder ähnliche Elemente.According to the invention, the lifting element between a vehicle-mounted receptacle and the support plate is arranged. The lifting element can be connected directly to the receptacle and / or the support plate. It is also conceivable that the lifting element is indirectly connected to the receptacle and / or the support plate, for example via an intermediate element such as a strut or similar elements.

Eine in konstruktiver Hinsicht vorteilhafte Ausgestaltung sieht vor, dass ein zweites Hubelement vorgesehen ist. Dieses Hubelement kann in Bezug auf das erste Hubelement spiegelsymmetrisch beispielsweise zu einer vertikalen Fahrzeuglängsmittelebene angeordnet sein, wodurch sich eine in Bezug auf die Fahrzeuglängsmittelebene symmetrische Ableitung der Abstützkräfte ergibt.A structurally advantageous embodiment provides that a second lifting element is provided. This lifting element can be arranged mirror-symmetrically with respect to the first lifting element, for example, to a vertical vehicle longitudinal center plane, resulting in a symmetrical with respect to the vehicle longitudinal median plane derivative of the supporting forces.

Die Erfindung sieht vor, dass mindestens eine Strebe zur Aufnahme von auf das Stützschild einwirkenden Querkräften vorgesehen ist. Das längenveränderbare Hubelement, bei dem es sich insbesondere um einen Hydraulikzylinder handeln kann, ist üblicherweise nur zur Aufnahme von in dessen Längsrichtung wirkenden Kräften ausgelegt bzw. geeignet. Über die Strebe lassen sich in gewissem Maße auch auf das Stützschild einwirkende Querkräfte aufnehmen, wie diese beispielsweise beim Absenken des Stützschilds auf einen nicht ebenen Untergrund entstehen können. Vorteilhaft sollte die Anzahl der Hubelemente der Anzahl der Streben entsprechen.The invention provides that at least one strut is provided for receiving transverse forces acting on the support plate. The length-variable lifting element, which may in particular be a hydraulic cylinder, is usually designed or suitable only for receiving forces acting in its longitudinal direction. About the strut can be added to some extent on the support shield acting transverse forces, such as may occur when lowering the support plate on a non-flat surface. Advantageously, the number of lifting elements should correspond to the number of struts.

Gemäß einer weiteren Ausgestaltung wird vorgeschlagen, dass die Streben zwischen den Hubelementen angeordnet sind. Insbesondere können zwei Streben zwischen zwei Hubelementen angeordnet sein. Sowohl die Anordnung der Streben als auch die Anordnung der Hubelemente kann, bezogen auf eine vertikale Längsmittelebene des Fahrzeugs, spiegelsymmetrisch sein.According to a further embodiment, it is proposed that the struts are arranged between the lifting elements. In particular, two struts can be arranged between two lifting elements. Both the arrangement of the struts and the arrangement of the lifting elements can, with respect to a vertical longitudinal center plane of the vehicle, be mirror-symmetrical.

In weiterer Ausgestaltung wird vorgeschlagen, dass ein stützschildseitiges Ende des Hubelements mit dem stützschildseitigen Ende der Strebe gelenkgekoppelt ist.In a further embodiment, it is proposed that a support plate-side end of the lifting element is articulated with the support plate end of the strut.

In diesem Zusammenhang wird weiter vorgeschlagen, dass die Streben eine Abwinklung aufweisen. Die Abwinklung kann insbesondere in einem Winkelbereich von 30° bis 50°, bevorzugt im Bereich von 40°, liegen.In this context, it is further proposed that the struts have an angling. The angling may in particular be in an angular range of 30 ° to 50 °, preferably in the range of 40 °.

Die Erfindung sieht vor, dass ein Ende der Streben an der Aufnahme angelenkt ist und das andere Ende der Streben translatorisch bewegbar mit dem Stützschild gekoppelt ist. Durch die translatorisch bewegbare Kopplung mit dem Stützschild lässt sich dieses in einer rein vertikalen Ebene absenken, wodurch sich ein geringer Raumbedarf für die Bewegung des Stützschilds zwischen dessen Abstütz- sowie Fahrstellung ergibt. Auch die Ableitung der Kräfte über das Stützschild erfolgt in vertikaler Richtung.The invention provides that one end of the struts is articulated to the receptacle and the other end of the struts is translationally coupled to the support plate. Due to the translationally movable coupling with the support plate, this can be lowered in a purely vertical plane, resulting in a small space requirement for the movement of the support plate between its support and driving position. The derivative of the forces on the support plate takes place in the vertical direction.

Gemäß einer alternativen Ausführung der Erfindung wird vorgeschlagen, dass ein Ende der Streben an dem Stützschild angelenkt ist und das andere Ende der Streben translatorisch bewegbar mit der Aufnahme gekoppelt ist.According to an alternative embodiment of the invention it is proposed that one end of the struts is hinged to the support plate and the other end of the struts is translationally coupled to the recording.

Von besonderem Vorteil ist eine Ausgestaltung, nach welcher die Streben derart ausgebildet und angeordnet sind, dass deren translatorisch bewegbares Ende sich infolge einer Längenänderung des Hubelements translatorisch gegenüber dem Stützschild oder der Aufnahme bewegt.Of particular advantage is an embodiment, according to which the struts are designed and arranged such that their translationally movable End moves due to a change in length of the lifting element translationally relative to the support plate or the recording.

Eine weitere, vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die Streben seitlich der Hubelemente angeordnet sind. Auch bei dieser Ausgestaltung ist es vorteilhaft, wenn zwei Streben und zwei Hubelemente vorgesehen sind, die spiegelsymmetrisch zu einer vertikalen Längsmittelebene des Fahrzeugs angeordnet sind.A further advantageous embodiment of the invention provides that the struts are arranged laterally of the lifting elements. Also in this embodiment, it is advantageous if two struts and two lifting elements are provided, which are arranged mirror-symmetrically to a vertical longitudinal center plane of the vehicle.

In einer nicht beanspruchten Ausgestaltung wird vorgeschlagen, dass die Streben ein Knickgelenk aufweisen. Über das Knickgelenkt kann ein Längenausgleich der Streben beim Anheben bzw. Absenken des Stützschilds erfolgen.In a non-claimed embodiment, it is proposed that the struts have an articulated joint. About the articulated can be made a length compensation of the struts when raising or lowering the support plate.

Eine weitere Ausgestaltung sieht vor, dass die Streben gelenkig mit der Aufnahme und dem Stützschild verbunden sind. Gegenüber einer translatorisch mit dem Stützschild verbundenen Strebe bietet diese Ausgestaltung den Vorteil einer geringeren Fehleranfälligkeit, da Verschmutzungen des Stützschildes und ähnliche Beeinträchtigungen die gelenkige Verbindung der Strebe mit dem Stützschild nicht zu beeinträchtigen vermögen.Another embodiment provides that the struts are pivotally connected to the receptacle and the support plate. Compared to a translationally connected to the support plate strut, this embodiment has the advantage of less susceptibility to errors, since contamination of the support plate and similar impairments are not able to affect the articulated connection of the strut with the support shield.

Gemäß einer besonders vorteilhaften Weiterbildung der Erfindung wird vorgeschlagen, dass die Abstützvorrichtung derart ausgebildet ist, dass in der Fahrstellung alle Elemente der Abstützvorrichtung tiefer als ein höchster Punkt der Aufnahme liegen. Mit Hilfe einer derartigen Ausgestaltung der Abstützvorrichtung wird erreicht, dass die Sicht des Fahrers bei angehobenem Stützschild nicht beeinträchtigt wird. Es ergeben sich eine in vertikaler Richtung betrachtet kompakte Bauweise der Abstützvorrichtung in deren Fahrstellung.According to a particularly advantageous embodiment of the invention it is proposed that the supporting device is designed such that in the driving position all elements of the supporting device are lower than a highest point of the recording. With the help of such an embodiment of the support device is achieved that the driver's view is not affected when the support plate is raised. This results in a viewed in a vertical direction compact design of the supporting device in the driving position.

Eine weitere Ausgestaltung sieht vor, dass die Abstützvorrichtung derart ausgebildet ist, dass sich das Stützschild infolge einer Betätigung der Hubvorrichtung in einer Ebene bewegt. Im Gegensatz zu einer Bewegung entlang einer Kreisbahn ergibt sich durch die Bewegung entlang einer Ebene ein geringer Platzbedarf beim Überführen des Stützschilds von einer Abstützstellung in eine Fahrstellung und umgekehrt.A further embodiment provides that the support device is designed such that the support plate moves as a result of an actuation of the lifting device in a plane. In contrast to a movement along a circular path resulting from the movement along a plane requires little space when transferring the support plate from a support position to a driving position and vice versa.

Schließlich wird in weiterer Ausgestaltung vorgeschlagen, dass die Abstützvorrichtung über eine Ein-Punkt-Schnittstelle mit dem Fahrzeug verbunden ist, die insbesondere als Flanschverbindung ausgestaltet sein kann. Während beim Stand der Technik mehrere Hubelemente an verschiedenen Stellen des Fahrzeugs montiert werden müssen, bietet die Verbindung über eine Ein-Punkt-Schnittstelle Vorteile insbesondere bei der Nachrüstung bereits im Betrieb befindlicher Fahrzeuge mit einer erfindungsgemäßen Abstützvorrichtung.Finally, it is proposed in a further embodiment that the support device is connected via a one-point interface with the vehicle, which may be configured in particular as a flange connection. While in the prior art, several lifting elements must be mounted at different points of the vehicle, the connection via a one-point interface offers advantages, especially in retrofitting already in operation vehicles with a supporting device according to the invention.

Fig. 1 zeigt in perspektivischer Darstellung ein Fahrzeug 1 mit einer in dessen Frontbereich angeordneten Abstützvorrichtung 2. Bei dem Fahrzeug 1 handelt es sich um ein Brückenverlegefahrzeug, wie diese im militärischen Bereich zum Verlegen von mobilen Brücken verwendet wird. Derartige auch als Pionierbrücken bezeichnete Brücken setzen sich aus mehreren, in Fig. 1 nicht dargestellten Brückenelementen zusammen, die ein oftmals erhebliches Gewicht aufweisen und auf der Oberseite des Fahrzeugs 1 bevorratet werden. Mittels des Fahrzeugs 1 können die Brückenelemente zu einem Einsatzort transportiert und über eine in Fig. 1 ebenfalls nicht dargestellte Verlegeeinrichtung verlegt werden. Fig. 1 shows a perspective view of a vehicle 1 with a arranged in the front area supporting device 2. The vehicle 1 is a bridge laying vehicle, as it is used in the military field for laying mobile bridges. Such bridges, also referred to as pioneer bridges, consist of several, in Fig. 1 bridge elements not shown together, which often have a considerable weight and are stored on the top of the vehicle 1. By means of the vehicle 1, the bridge elements to a site transported and over an in Fig. 1 also not shown laying device to be laid.

Da sich beim Verlegen der Brückenelemente aufgrund deren weit über die Kontur des Fahrzeugs 1 hinausragender Stellung ungünstige Schwerpunktverhältnisse ergeben, ist im Frontbereich des Fahrzeugs 1 die Abstützvorrichtung 2 vorgesehen, die über ein Stützschild 4 einen zusätzlichen Abstützpunkt bereitstellt.Since unfavorable center of gravity relationships result when laying the bridge elements due to their position protruding far beyond the contour of the vehicle 1, the supporting device 2 is provided in the front region of the vehicle 1, which provides an additional support point via a support plate 4.

Nachfolgend wird zunächst auf Einzelheiten der Verbindung der Abstützvorrichtung 2 mit dem Fahrzeug 1 eingegangen werden, bevor dann die Funktionsweise der Abstützvorrichtung 2 im Einzelnen erläutert werden wird.Subsequently, details of the connection of the supporting device 2 to the vehicle 1 will first be discussed, before the functioning of the supporting device 2 will be explained in detail.

Wie die Darstellung in Fig. 1 erkennen lässt, ist die Abstützvorrichtung 2 über eine Ein-Punkt-Schnittstelle 20 an das Fahrzeug 1 angebunden. Die Ein-Punkt-Schnittstelle 20 bildet die einzige Verbindungsstelle zwischen dem Fahrzeug 1 und der Abstützvorrichtung 2. Die Ein-Punkt-Schnittstelle 20 ist nach Art einer Flanschverbindung mit einer fahrzeugfesten Flanschplatte 21 ausgebildet, an welche eine Aufnahme 6 der Abstützvorrichtung 2 angebunden ist.Like the illustration in Fig. 1 can be seen, the support device 2 is connected via a one-point interface 20 to the vehicle 1. The one-point interface 20 forms the only connection point between the vehicle 1 and the support device 2. The one-point interface 20 is formed in the manner of a flange with a vehicle-fixed flange plate 21, to which a receptacle 6 of the support device 2 is connected.

Neben dieser mechanischen Verbindung der Abstützvorrichtung 2 mit dem Fahrzeug 1 sind im Bereich der Ein-Punkt-Schnittstelle 20 auch die Schnittstellen für die zum Betrieb der Abstützvorrichtung 2 erforderlichen Versorgungsleitungen vorgesehen, beispielsweise Anschlüsse für die Herstellung einer hydraulischen Verbindung.In addition to this mechanical connection of the supporting device 2 to the vehicle 1, the interfaces for the supply lines required for operating the supporting device 2 are provided in the area of the one-point interface 20, for example, connections for the production of a hydraulic connection.

Die Ein-Punkt-Schnittstelle 20 erlaubt eine wenige Montageschritte erfordernde Befestigung der Abstützvorrichtung 2 an dem Fahrzeug 1 und eignet sich insbesondere auch als Nachrüstlösung für bereits im Betrieb befindliche Fahrzeuge 1, die mit einer entsprechenden Abstützvorrichtung 2 nachgerüstet werden sollen. Im Falle einer solchen Nachrüstung muss neben der Bereitstellung entsprechender Versorgungsanschlüsse lediglich eine Flanschplatte 21 an der Außenkontur des Fahrzeugs 1 beispielsweise durch Schweißen befestigt werden. Anschließend wird die Aufnahme 6 durch Verschrauben mit der Flanschplatte 21 verbunden und die Versorgungsleitungen angeschlossen.The one-point interface 20 allows a few installation steps requiring attachment of the support device 2 to the vehicle 1 and is particularly suitable as a retrofit solution for already in operation vehicles 1, which are to be retrofitted with a corresponding support device 2. In the case of such retrofitting, in addition to the provision of corresponding supply connections, only one flange plate 21 has to be fastened to the outer contour of the vehicle 1, for example by welding. Subsequently, the receptacle 6 is connected by screwing with the flange plate 21 and the supply lines connected.

Wie nachfolgend im Einzelnen dargelegt werden wird, zeichnet sich die Abstützvorrichtung 2 insbesondere auch dadurch aus, dass das Stützschild 4 auf engem Raum zwischen einer Abstützstellung, wie diese in Fig. 1 dargestellt ist, und einer höher liegenden Fahrstellung hin- und her bewegbar ist und in der Fahrstellung eine kompakte Stellung einnimmt.As will be explained in detail below, the support device 2 is characterized in particular by the fact that the support plate 4 in a small space between a support position, as in Fig. 1 is shown, and a higher-lying driving position is movable back and forth and occupies a compact position in the driving position.

Zum Anheben bzw. Absenken des Stützschilds 4 ist eine Hubvorrichtung 3 vorgesehen, die bei der Ausführung gemäß Fig. 1 zwei längenveränderbare, als Hydraulikzylinder ausgebildete Hubelemente 5 aufweist. Im Bereich zwischen den Hubelementen 5 sind zwei Streben 7 zur Aufnahme von auf das Stützschild 4 wirkenden Querkräften vorgesehen.For raising or lowering the support plate 4, a lifting device 3 is provided, which in the embodiment according to Fig. 1 has two variable in length, designed as a hydraulic cylinder lifting elements 5. In the area between the lifting elements 5, two struts 7 are provided for receiving transverse forces acting on the support plate 4.

Sowohl die Streben 7 als auch die Hubelemente 5 sind mit einem Ende innerhalb der im Querschnitt U-förmig ausgebildeten Aufnahme 6 schwenkbeweglich um sich in Fahrzeuglängsrichtung erstreckende Achsen A angelenkt. Stützschildseitig sind die Hubelemente 5 mit dem stützschildseitigen Ende 7.1 der Streben 7 gelenkig verbunden. Der Anlenkpunkt jeweils eines Hubelements 5 in der Aufnahme 6 bildet gemeinsam mit dem Anlenkpunkt der zugehörigen Strebe 7 und dem Verbindungspunkt des Hubelements 5 mit dem stützschildseitigen Ende 7.1 der Strebe 7 eine Art Dreieck, dessen durch das Hubelement 5 gebildete Seite längenveränderbar ist. Bei Betätigung des Hubelements 5 ändert sich dessen Länge, wodurch sich die Winkel des Dreiecks ändern und das Stützschild 4 angehoben oder abgesenkt werden kann.Both the struts 7 and the lifting elements 5 are hinged at one end within the U-shaped in cross-section receptacle 6 pivotally about extending in the vehicle longitudinal direction axes A. Support shield side, the lifting elements 5 are hingedly connected to the support plate side end 7.1 of the struts 7. The articulation point of each lifting element 5 in the receptacle 6 forms together with the articulation point of the associated strut 7 and the connection point of the lifting element 5 with the support plate end 7.1 of the strut 7 a kind of triangle whose side formed by the lifting element 5 is variable in length. Upon actuation of the lifting element. 5 changes its length, which change the angle of the triangle and the support plate 4 can be raised or lowered.

Das stützschildseitige Ende 7.1 der Streben 7 ist darüber hinaus mit dem Abstützschild 4 verbunden, wobei der entsprechende Verbindungspunkt translatorisch gegenüber dem Stützschild 4 bewegbar angeordnet ist. Durch Betätigung des Hubelements 5 kann das Stützschild 4 beispielsweise von der in Fig. 1 dargestellten Abstützstellung in eine höher liegende Fahrstellung angehoben werden, wobei sich das stützschildseitigen Ende 7.1 der Strebe 7 gegenüber dem Stützschild 4 translatorisch nach fahrzeugaußen bewegt, vgl. auch Fig. 2 und Fig. 4.The support plate end 7.1 of the struts 7 is also connected to the support plate 4, wherein the corresponding connection point is arranged translationally relative to the support plate 4 movable. By actuating the lifting element 5, the support plate 4, for example, from the in Fig. 1 shown support position are raised in a higher driving position, with the support plate end 7.1 of the strut 7 relative to the support plate 4 translationally moved to vehicle outside, see. also 2 and FIG. 4 ,

Fig. 2 zeigt das Fahrzeug 1 in einer schematisierten Frontansicht, in welcher sich das Stützschild 4 in dessen Fahrstellung befindet. Zu erkennen ist, dass sämtliche Elemente 5, 7 der Hubvorrichtung 3 spiegelsymmetrisch bezüglich einer vertikalen Längsmittelebene L des Fahrzeugs 1 angeordnet sind. Die Elemente 5, 7 der Hubvorrichtung 3 reichen in vertikaler Richtung nicht über die Aufnahme 6 hinaus, die auch in der Fahrstellung einen höchsten Punkt der Abstützvorrichtung 2 bildet. In der in Fig. 2 dargestellten Fahrstellung nimmt die Abstützvorrichtung 2 eine kompakte Stellung ein, weshalb die Sicht des Fahrzeugführers, der beispielsweise über ein Sichtelement 30 aus dem Fahrzeuginneren nach außen blickt, durch die Abstützvorrichtung 2 nicht beeinträchtigt wird. Fig. 2 shows the vehicle 1 in a schematic front view, in which the support plate 4 is in its driving position. It can be seen that all the elements 5, 7 of the lifting device 3 are arranged mirror-symmetrically with respect to a vertical longitudinal center plane L of the vehicle 1. The elements 5, 7 of the lifting device 3 do not extend beyond the receptacle 6 in the vertical direction, which also forms a highest point of the supporting device 2 in the driving position. In the in Fig. 2 illustrated driving position, the support device 2 assumes a compact position, which is why the view of the driver, for example, looks over a viewing element 30 from the vehicle interior to the outside, is not affected by the support device 2.

Zum Absenken des Stützschilds aus der in den Fign. 2 und 3 dargestellten Fahrstellung werden die Hubelemente 5 ausgefahren, wodurch diese in der Aufnahme 6 um eine sich in Fahrzeuglängsrichtung erstreckende Achse A zu verschwenken beginnen. Dabei beginnen auch die Streben 7 in einer entsprechenden Richtung zu verschwenken. Um die Schwenkbewegung der Streben 7 zu vereinfachen, weisen diese eine Abwinklung 7.3 auf. Sowohl die Schwenkbewegung der Hubelemente 5 als auch jene der Streben 7 erfolgt in einer vertikalen Fahrzeugquerebene, vgl. Fig. 3 und Fig. 5, was eine Bewegung des Stützschilds 4 auf engem Raum ermöglicht.To lower the support plate from the in the FIGS. 2 and 3 illustrated driving position, the lifting elements 5 are extended, whereby they begin to pivot in the receptacle 6 about an axis A extending in the vehicle longitudinal direction. At the same time, the struts 7 also begin to pivot in a corresponding direction. To the pivoting movement of the struts 7 to simplify, they have a bend 7.3. Both the pivotal movement of the lifting elements 5 and those of the struts 7 takes place in a vertical vehicle transverse plane, cf. FIG. 3 and FIG. 5 , which allows movement of the support plate 4 in a small space.

Um die zum Längenausgleich erforderliche Relativbewegung des stützschildseitigen Endes 7.1 der Streben 7 gegenüber dem Stützschild 4 zu ermöglichen, ist das Stützschild 4 mit einer Langlochführung 8 versehen, innerhalb welcher das Ende 7.1 geführt gleiten kann. Nachdem die Hubzylinder 5 ihre maximale Länge erreicht haben, befindet sich das Stützschild 4 in der in den Fig. 4 und Fig. 5 dargestellten Abstützstellung. Wie zu erkennen ist, ist die Hubvorrichtung 3 derart ausgelegt, dass das Stützschild 4 nicht nur bis in eine Standebene 40 des Fahrzeugs 1 abgesenkt werden kann, sondern bis in eine darunter liegende Ebene 41, die vorzugsweise um mindestens 20 cm tiefer liegt als die Standebene 40, um auch bei abschüssigem Gelände eine zuverlässige Abstützwirkung erreichen zu können.In order to allow for length compensation required relative movement of the support plate end 7.1 of the struts 7 relative to the support plate 4, the support plate 4 is provided with a slot guide 8, within which the end 7.1 can slide guided. After the lifting cylinder 5 have reached their maximum length, the support plate 4 is in the in the 4 and FIG. 5 shown support position. As can be seen, the lifting device 3 is designed such that the support plate 4 can not only be lowered into a standing plane 40 of the vehicle 1, but up to an underlying level 41, which is preferably at least 20 cm lower than the standing level 40 in order to achieve a reliable supporting effect even on sloping terrain.

Wie darüber hinaus die Darstellung in Fig. 6 erkennen lässt, erlaubt die erfindungsgemäße Abstützvorrichtung 2 aufgrund der Schwenkbeweglichkeit der Elemente 5, 7 der Hubvorrichtung 3 um sich in Fahrzeuglängsrichtung erstrekkende Achsen A in gewissem Maße auch eine Schrägstellung des Stützschildes 4 gegenüber der Horizontalen, wie diese ebenfalls zum Ausgleich von Geländeunebenheiten erforderlich ist. Im Falle solcher Geländeunebenheiten kann die Abstützung derart erfolgen, dass die Hydraulikzylinder kraftgeregelt jeweils die gleiche Kraft auf das Stützschild 4 übertragen, bis die in Fig. 6 dargestellte Endlage erreicht ist.As well as the presentation in Fig. 6 can be seen, the support device 2 according to the invention allows due to the pivoting movement of the elements 5, 7 of the lifting device 3 extending in the vehicle longitudinal axes A to some extent, a tilt of the support plate 4 relative to the horizontal, as this is also required to compensate for uneven terrain. In the case of such terrain bumps, the support can be made such that the hydraulic cylinder force-controlled in each case transmit the same force on the support plate 4 until the in Fig. 6 shown end position is reached.

Eine nicht beanspruchte Ausführung ist in den Fig. 7 bis 11 dargestellt.An unclaimed design is in the Fig. 7 to 11 shown.

Im Gegensatz zu der anhand der Darstellungen in den Fig. 1 bis 6 beschriebenen Ausführung sind bei dieser Ausführung die Hubelemente 5 zwischen den Streben 7 vorgesehen. Die Hubelemente 5 sind um eine gemeinsame, sich in Fahrzeuglängsrichtung erstreckende Achse A angelenkt und stützschildseitig mit dem Stützschild 4 gelenkig verbunden. Die Streben 7 sind zur Aufnahme von auf das Stützschild 4 wirkenden Querkräften sowohl mit der Aufnahme 6 als auch dem Stützschild 4 gelenkig verbunden. Um ein Verkanten der Streben 7 während einer Längenveränderung der Hubelemente 5 zu vermeiden, weisen die Streben 7 gemäß dieser Ausführung ein Knickgelenk 7.4 auf.In contrast to the representations in the Fig. 1 to 6 described embodiment, the lifting elements 5 are provided between the struts 7 in this embodiment. The lifting elements 5 are articulated about a common, extending in the vehicle longitudinal direction axis A and supporting plate side hingedly connected to the support plate 4. The struts 7 are connected to receive acting on the support plate 4 transverse forces with both the receptacle 6 and the support plate 4 hinged. In order to avoid tilting of the struts 7 during a change in length of the lifting elements 5, the struts 7 according to this embodiment, an articulation 7.4.

Die vorstehend beschriebene Abstützvorrichtung 4 bzw. ein Fahrzeug 1 mit einer solchen Abstützvorrichtung 4 zeichnen sich insbesondere dadurch aus, dass das Stützschild 4 in einer rein translatorischen Bewegung entlang einer vertikalen Ebene bewegbar ist, wodurch sich eine kompakte Geometrie der Abstützvorrichtung 4 in der Fahrstellung ergibt. In der Fahrstellung liegen sämtliche Elemente der Abstützvorrichtung 4 tiefer als ein höchster Punkt der Aufnahme 6, so dass die Sicht des Fahrzeugführers bei angehobenem Stützschild 4 durch dieses nicht beeinträchtigt wird. Darüber hinaus werden die Abstützkräfte in rein vertikaler Richtung abgeleitet.The support device 4 described above or a vehicle 1 with such a support device 4 are characterized in particular in that the support plate 4 is movable in a purely translational movement along a vertical plane, resulting in a compact geometry of the support device 4 in the driving position. In the driving position all elements of the support device 4 are deeper than a highest point of the receptacle 6, so that the view of the driver is not affected by the support plate 4 raised by this. In addition, the support forces are derived in a purely vertical direction.
