Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Festlegen eines Straßendienstgeräts an einem Fahrzeug. Typischer Weise ist ein Straßendienstgerät, das mit der erfindungsgemäßen Vorrichtung festgelegt wird, ein Schneepflug.The present invention relates to a device for setting a road service device on a vehicle. Typically, a road service device that is fixed with the device according to the invention is a snow plow.
Ein Straßendienstgerät und insbesondere ein Schneepflug soll für einen normgerechten Einsatz in Bezug auf das Fahrzeug, auf dem der Schneepflug angeordnet ist, eine gewisse Beweglichkeit aufweisen. Insbesondere sollte der Schneepflug gehoben und gesenkt, schräg zur Fahrbahnrichtung gestellt und bevorzugt schräg zur Horizontalen gestellt werden können. Zur Anpassung an Krümmungen der Straße, besteht ein Schneepflug in der Regel darüber hinaus aus einer Mehrzahl von Schildern, die über Federelemente beweglich mit einem Trägerrahmen verbunden sindA road service device and in particular a snow plow should have a certain mobility in relation to the vehicle on which the snow plow is arranged so that it can be used in accordance with standards. In particular, the snow plow should be able to be raised and lowered, positioned at an angle to the direction of the road and preferably at an angle to the horizontal. To adapt to curvatures in the road, a snow plow usually consists of a plurality of blades that are movably connected to a support frame via spring elements
Um die notwendige Verstellbarkeit zu gewährleisten, umfasst daher eine bekannte Vorrichtung der eingangs genannten Art eine an dem Fahrzeug festlegbare Anbauplatte, einen Geräteträger und einen am Geräteträger angeordneten Geräteadapter, wobei sich zumindest ein an einer ersten horizontalen Achse schwenkbar an der Anbauplatte festgelegter Oberlenker und zumindest ein an einer zweiten horizontalen Achse schwenkbar an der Anbauplatte festgelegter Unterlenker zum Geräteträger erstrecken und der Geräteträger am Oberlenker an einer dritten horizontalen Achse und am Unterlenker an einer vierten horizontalen Achse schwenkbar festgelegt ist. Hierbei bilden die erste Achse und die zweite Achse ein erstes Achspaar und die dritte Achse und die vierte Achse ein zweites Achspaar mit jeweils parallel zueinander verlaufenden Achsen. Hierdurch wird eine Parallelogrammanlenkung zwischen Anbauplatte und Geräteträger geschaffen, was es ermöglicht, den Geräteträger parallel zur Anbauplatte anzuheben beziehungsweise abzusenken, sodass der Abstand der Unterkante des Schneepflugs zur Fahrbahn eingestellt werden kann. Weiters weist der Geräteadapter eine vertikale Achse zum verschwenkbaren Festlegen des Straßendienstgeräts auf, sodass der Schnee zur Seite der Fahrbahn gefördert und abgeworfen wird. In den allermeisten Fällen ist auch ein Verkippen des Straßendienstgeräts um eine horizontale Längsachse erforderlich, um auch Straßen räumen zu können, die bombiert sind oder nach einer Seite hängen.In order to ensure the necessary adjustability, a known device of the type mentioned at the outset therefore comprises a mounting plate that can be fixed to the vehicle, a device carrier and a device adapter arranged on the device carrier, with at least one upper link pivotably fixed to the mounting plate on a first horizontal axis and at least one on a second horizontal axis, the lower link pivotably fixed to the mounting plate extends to the equipment carrier and the equipment carrier is pivotally secured to the upper link on a third horizontal axis and to the lower link on a fourth horizontal axis. Here, the first axis and the second axis form a first pair of axes and the third axis and the fourth axis form a second pair of axes, each with axes running parallel to one another. This creates a parallelogram linkage between the mounting plate and the equipment carrier, which makes it possible to lift the equipment carrier parallel to the mounting plate or lowered so that the distance between the lower edge of the snow plow and the road can be adjusted. Furthermore, the device adapter has a vertical axis for pivotally fixing the road service device so that the snow is conveyed to the side of the road and thrown off. In the vast majority of cases, it is also necessary to tilt the road service device around a horizontal longitudinal axis in order to be able to clear roads that are cambered or slope to one side.
Die Anbindung eines Schneepflugs an das entsprechende Zugoder Schubfahrzeug hat entscheidenden Einfluss auf das Räumergebnis und das Fahrverhalten des mit dem Schneepflug versehenen Fahrzeugs. So soll zum einen die Vorrichtung zum Festlegen eines Schneepflugs an einem Fahrzeug in Fahrtrichtung gesehen möglichst kurz ausgebildet sein, um die am Fahrzeug auftretenden Achslasten möglichst gering zu halten. Zum anderen ist es aber hinsichtlich der Laufruhe eines Schneepflugs als vorteilhaft zu betrachten, wenn die Oberlenker und die Unterlenker im Vergleich zur Gesamtlänge der Vorrichtung möglichst lange sind.The connection of a snow plow to the corresponding towing or pushing vehicle has a decisive influence on the clearing results and the driving behavior of the vehicle equipped with the snow plow. On the one hand, the device for fixing a snow plow on a vehicle should be as short as possible when viewed in the direction of travel in order to keep the axle loads occurring on the vehicle as low as possible. On the other hand, with regard to the smooth running of a snow plow, it is to be considered advantageous if the upper links and the lower links are as long as possible compared to the overall length of the device.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, bei einer möglichst geringen Baulänge einer Vorrichtung der eingangs genannten Art Oberlenker und Unterlenker möglichst lange auszugestalten, um die beiden genannten vorteilhaften Effekte möglichst in gleichem Maße zu erzielen.The present invention is therefore based on the object of making the upper link and lower link as long as possible with the shortest possible overall length of a device of the type mentioned in order to achieve the two advantageous effects mentioned to the same extent as possible.
Erfindungsgemäß ist daher eine Vorrichtung der eingangs genannten Art dahingehend weitergebildet, dass die vertikale Achse zumindest eine Achse des zweiten Achspaares schneidet oder zwischen zumindest einer Achse des zweiten Achspaares und dem ersten Achspaar verläuft. Im Gegensatz zu Vorrichtungen der eingangs genannten Art, die im Stand der Technik bereits bekannt geworden sind, sieht die Erfindung vor, die Achse für die vertikale Verschwenkbarkeit in den Bereich des zweiten Achspaares oder sogar zwischen die Achspaare zu verlagern. Hierdurch wird die Funktionalität der seitlichen Verschwenkbarkeit und des Verkippens gegenüber der Horizontalen durch Achsen bereitgestellt, die nicht über die Parallelogrammanlenkung, der durch die ersten und zweiten Achspaare begrenzt ist, hinausgehen, sodass sich Oberlenker und Unterlenker im Wesentlichen über die gesamte Länge der erfindungsgemäßen Vorrichtung erstrecken können. Oberlenker und Unterlenker können sich auf diese Weise bei der erfindungsgemäßen Vorrichtung bevorzugt über 95% der Gesamtbaulänge der Vorrichtung erstrecken.According to the invention, a device of the type mentioned is therefore further developed in such a way that the vertical axis intersects at least one axis of the second pair of axles or runs between at least one axis of the second pair of axles and the first pair of axles. Unlike fixtures of the type mentioned at the beginning, which have already become known in the prior art, the invention provides for the axis for vertical pivoting to be relocated into the area of the second pair of axles or even between the pairs of axles. As a result, the functionality of lateral pivoting and tilting relative to the horizontal is provided by axes that do not go beyond the parallelogram linkage, which is limited by the first and second pairs of axles, so that the upper link and lower link extend essentially over the entire length of the device according to the invention can. In this way, the upper link and lower link can preferably extend over 95% of the total length of the device in the device according to the invention.
Um die erfindungsgemäße Vorrichtung verwindungssteif zu gestalten, ist die vorliegende Erfindung gemäß einer bevorzugten Ausführungsform dahingehend weitergebildet, dass jeweils zwei Oberlenker an der ersten Achse und zwei Unterlenker an der zweiten Achse festgelegt sind. Auf diese Weise wird der Geräteträger möglichst breit an der Anbauplatte abgestützt, sodass einer Tendenz zum seitlichen Verkippen wirksam entgegengewirkt wird. Damit beim seitlichen Verschwenken des Schneepflugs genügend Platz zur Verfügung steht, ohne dass der Schneepflug mit Oberlenker oder Unterlenker kollidiert, ist die Erfindung in diesem Zusammenhang bevorzugt dahingehend weitergebildet, dass sich die Oberlenker und die Unterlenker geräteträgerseitig jeweils zu einem gemeinsamen Oberlenker und einem gemeinsamen Unterlenker vereinigen.In order to make the device according to the invention torsion-resistant, the present invention is further developed according to a preferred embodiment in such a way that two upper links are fixed to the first axle and two lower links are fixed to the second axle. In this way, the equipment carrier is supported as widely as possible on the mounting plate, so that any tendency to tilt to the side is effectively counteracted. So that there is enough space available when the snow plow is pivoted sideways without the snow plow colliding with the upper link or lower link, the invention is preferably further developed in this context in such a way that the upper link and the lower link each combine on the equipment carrier side to form a common upper link and a common lower link .
Für eine symmetrische Krafteinleitung in die erfindungsgemäße Vorrichtung ist es gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung vorgesehen, dass die vertikale Achse jeweils zwischen den Oberlenkern und den Unterlenkern verläuft. Die Kraft, die beim Beiseiteschieben von Schnee durch einen Schneepflug auf die erfindungsgemäße Vorrichtung wirkt, wird gemäß dieser Ausführungsform mittig auf die beiden Oberlenker und Unterlenker übertragen und kann mit möglichst geringen Momenten auf die Anbauplatte abgeleitet werden.For a symmetrical introduction of force into the device according to the invention, according to a preferred embodiment The present invention provides that the vertical axis runs between the upper links and the lower links. The force that acts on the device according to the invention when snow is pushed aside by a snow plow is, according to this embodiment, transmitted centrally to the two upper links and lower links and can be transferred to the mounting plate with the lowest possible moments.
Um, wie eingangs erwähnt, auch eine Anpassung der Neigung des Schneepflugs an geneigte und bombierte Fahrbahnoberflächen zu ermöglichen, kann die vorliegende Erfindung bevorzugt dahingehend weitergebildet sein, dass der Geräteadapter an einer fünften horizontalen Achse verschwenkbar am Geräteträger gelagert ist, die quer zu den Achsen der Achspaare verläuft. Diese fünfte horizontale Achse verläuft somit in Längsrichtung der erfindungsgemäßen Vorrichtung beziehungsweise des Fahrzeugs und gestattet es, den Schneepflug an schräg verlaufende Fahrbahnen angepasst zu verkippen.In order, as mentioned at the beginning, to also enable the inclination of the snow plow to be adapted to inclined and cambered road surfaces, the present invention can preferably be further developed in such a way that the device adapter is pivotably mounted on the device carrier on a fifth horizontal axis, which is transverse to the axes of the Axle pairs runs. This fifth horizontal axis thus runs in the longitudinal direction of the device according to the invention or of the vehicle and allows the snow plow to be tilted to suit inclined roadways.
Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung bilden der Geräteadapter und der Geräteträger jeweils eine Box aus, wobei die Box des Geräteadapters in die Durchbrechungen für den Durchtritt der vertikalen Achse aufweisende Box des Geräteträgers eingesetzt ist und wobei die fünfte Achse am Boden einer der beiden Boxen ausgebildet ist und im Boden der anderen der beiden Boxen angreift und wobei der Geräteadapter und der Geräteträger miteinander in Eingriff bringbare Verbindungsmittel in einem Bereich zwischen zumindest einer Achse des zweiten Achspaares und dem ersten Achspaar aufweisen, welche Verbindungsmittel eine Verschwenkung des Geräteadapters bezüglich des Geräteträgers um die fünfte horizontale Achse gestatten. Auf diese Weise wird die Funktionalität des Verkippens des angebauten Schneepflugs zum Räumen bombierter oder zu einer Seite geneigter Straßen ebenso mittig wie die Funktionalität des seitlichen Verschwenkens durch die horizontale Achse realisiert. Damit dies möglich wird, wird gemäß dieser bevorzugten Ausführungsform der vorliegenden Erfindung die fünfte Achse lediglich durch einen Angriffspunkt am Boden einer der beiden Boxen ausgebildet und die mit der fünften Achse, der Längsachse, zu übertragenden Kräfte mittels der Boxen um die vertikale Achse herumgeleitet. Gleichzeitig werden die Boxen aber in den Bereich zwischen den Achspaaren gebaut, damit wiederum insgesamt eine geringe Baulänge im Vergleich zur Erstreckung der Oberlenker und Unterlenker resultiert. Durch die Verbindungsmittel werden die Boxen aneinandergehalten. Das gekrümmte Langloch weist eine Krümmung auf, die der Kreisbahn entspricht, die der Geräteadapter bezüglich des Geräteträgers beim Verkippen beschreibt.According to a preferred embodiment of the present invention, the device adapter and the device carrier each form a box, the box of the device adapter being inserted into the openings for the passage of the vertical axis of the device carrier, and the fifth axis being formed on the bottom of one of the two boxes is and engages in the bottom of the other of the two boxes and wherein the device adapter and the device carrier have connecting means which can be brought into engagement with one another in an area between at least one axis of the second pair of axles and the first pair of axles, which connecting means enable the device adapter to be pivoted relative to the device carrier by the fifth allow horizontal axis. In this way the functionality of tilting the attached The snow plow for clearing cambered streets or streets that slope to one side is implemented in the middle, as is the functionality of lateral pivoting through the horizontal axis. To make this possible, according to this preferred embodiment of the present invention, the fifth axis is only formed by a point of application on the bottom of one of the two boxes and the forces to be transmitted with the fifth axis, the longitudinal axis, are directed around the vertical axis by means of the boxes. At the same time, the boxes are built in the area between the pairs of axles, which results in a short overall length compared to the extension of the upper and lower links. The boxes are held together by the connecting means. The curved elongated hole has a curvature that corresponds to the circular path that the device adapter describes with respect to the device carrier when tilted.
Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung sind die Verbindungsmittel von gekrümmten Langlöchern und die Langlöcher durchsetzenden Bolzen gebildet. Hierbei können die Langlöcher am Geräteträger oder am Geräteadapter angeordnet sein, jedenfalls ist dementsprechend jeweils ein Bolzen am jeweils anderen Teil aus der Gruppe bestehend aus Geräteträger und Geräteadapter vorzusehen, der das Langloch durchsetzt und mit einer Mutter im Langloch gesichert wird.According to a preferred embodiment of the present invention, the connecting means are formed by curved elongated holes and bolts passing through the elongated holes. The elongated holes can be arranged on the device carrier or on the device adapter; in any case, a bolt must be provided on the other part of the group consisting of the device carrier and device adapter, which passes through the elongated hole and is secured in the elongated hole with a nut.
Wie schon beim Antrieb der Verschwenkbewegung des Geräteadapters um die fünfte horizontale Achse, kann es bevorzugt vorgesehen sein, dass Oberlenker und Unterlenker mittels zumindest eines Hydraulikzylinders zum Verschwenken antreibbar sind. Auch hier sind wiederum andere Ausführungsformen denkbar, bei denen Stellmotoren oder Spindelantriebe zum Einsatz gelangen, der Antrieb mittels Hydraulikzylindern ist jedoch besonders kraftvoll, unempfindlich gegenüber Stößen und Schlägen, die vom Schneepflug auf die erfindungsgemäße Vorrichtung einwirken, und kann darüber hinaus ein Hydrauliksystem nutzen, das üblicher Weise an Schub- oder Zugfahrzeugen, in aller Regel Lastkraftwagen, vorhanden sind. Darüber hinaus kann es gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung auch vorgesehen sein, die Verkippbewegung um die fünfte horizontale Achse durch einen Hydraulikzylinder zu bewerkstelligen.As with the drive of the pivoting movement of the device adapter about the fifth horizontal axis, it can preferably be provided that the upper link and lower link can be driven for pivoting by means of at least one hydraulic cylinder. Here too, other embodiments are conceivable, in which servomotors or Spindle drives are used, but the drive by means of hydraulic cylinders is particularly powerful, insensitive to shocks and impacts that act on the device according to the invention from the snow plow, and can also use a hydraulic system that is usually found on push or towing vehicles, usually trucks , available. In addition, according to a preferred embodiment of the present invention, it can also be provided that the tilting movement about the fifth horizontal axis is carried out by a hydraulic cylinder.
Aus denselben Gründen ist die vorliegende Erfindung bevorzugt dahingehend weitergebildet, dass am Geräteadapter zumindest ein Hydraulikzylinder gelagert ist, der mit einem am Geräteadapter verschwenkbar festgelegten Straßendienstgerät, insbesondere Schneepflug, verbindbar ist. Auf diese Weise kann beispielsweise der Schneepflug um die vertikale Achse zu den Seiten einer Fahrbahn verschwenkt werden, um Schnee neben die Fahrbahn zu fördern.For the same reasons, the present invention is preferably further developed in such a way that at least one hydraulic cylinder is mounted on the device adapter and can be connected to a road service device, in particular a snow plow, which is pivotably attached to the device adapter. In this way, for example, the snow plow can be pivoted about the vertical axis to the sides of a road in order to convey snow next to the road.
Gemäß einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung umfasst die erfindungsgemäße Vorrichtung weiters einen Trägerrahmen zum Festlegen des Straßendienstgeräts und ist dadurch gekennzeichnet, dass der Trägerrahmen schwenkbar am Geräteadapter angelenkt ist und dergestalt angeordnet ist, dass der Trägerrahmen zumindest eine Achse des zweiten Achspaares schneidet oder zwischen zumindest einer Achse des zweiten Achspaares und dem ersten Achspaar verläuft. Dies bedeutet, dass auch der Trägerrahmen nicht über die Parallelogrammanlenkung, der durch die ersten und zweiten Achspaare begrenzt ist, hinausreicht, sodass sich Oberlenker und Unterlenker wiederum im Wesentlichen über die gesamte Länge der erfindungsgemäßen Vorrichtung erstrecken können. Oberlenker und Unterlenker können sich auf diese Weise bei der erfindungsgemäßen Vorrichtung bevorzugt über 95% der Gesamtbaulänge der Vorrichtung erstrecken.According to a further preferred embodiment of the present invention, the device according to the invention further comprises a support frame for fixing the road service device and is characterized in that the support frame is pivotally articulated on the device adapter and is arranged in such a way that the support frame intersects at least one axis of the second pair of axles or at least between an axis of the second pair of axles and the first pair of axles. This means that the support frame does not extend beyond the parallelogram linkage, which is limited by the first and second pairs of axles, so that the upper link and lower link essentially extend over the can extend the entire length of the device according to the invention. In this way, the upper link and lower link can preferably extend over 95% of the total length of the device in the device according to the invention.
