Description

Die Erfindung betrifft ein Anbaugerät für ein Kraftfahrzeug, insbesondere Schneepflug, Schneefräse od. dgl., mit einem an das Kraftfahrzeug anschließbaren Gestell und mit einem im Gestell gelagerten Räumschild.The invention relates to an attachment for a motor vehicle, in particular snow plow, snowthrower od. Like., With a connectable to the motor vehicle frame and with a mounted in the frame plow blade.

Die bekannten, verstellbar an Fahrzeugen montierbaren Räumschilde tragen üblicherweise eine den unteren Rand des Räumschildes bildende Räumleiste, die zum Befreien einer Fahrbahn von Schnee und Eis die Fahrbahn entlang gleitend geschoben od. dgl. wird und das von der Fahrbahn abgeschabte Gut über den Räumschild seitlich aus dem Räumbereich verfrachtet. Da Straßen seitlich meist mit Leitschienen, Leitwänden od. dgl. gesichert sind, besteht beim Einsatz von Schneepflügen auf derart gesicherten Straßen das Problem, daß Leitschienen bzw. Leitwände und/oder der Räumschild bei gegenseitigem Kontakt beschädigt werden, was sich in weiterer Folge auch in einer erhöhten Korrosion und somit geringerer Standzeit der einzelnen Bauteile bemerkbar macht.The well-known, adjustable mounted on vehicles Räumschilde usually wear a the bottom of the plow blade forming scraper sliding the road to clear a road surface of snow and ice along the road od. Like. And the scrapped from the road Good on the plow blade side the clearing area shipped. Since roads are usually sideways with guide rails, guide walls od. Like. Are secured when using snow plows on such secure roads, the problem that guide rails or baffles and / or the dozer blade are damaged in mutual contact, which is subsequently in an increased corrosion and thus less service life of the individual components makes noticeable.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Anbaugerät der eingangs geschilderten Art zu schaffen, mit dem Beschädigungen von Leitschienen, Leitwänden od. dgl. neben dem Räumbereich befindlichen Objekten durch den Räumschild vermieden werden.The invention is therefore an object of the invention to provide an attachment of the type described, od with the damage of rails, baffles. The like. Located next to the clearing area objects are avoided by the plow blade.

Die Erfindung löst diese Aufgabe dadurch, daß eine über den Seitenrand des Räumschildes hinausragende Seitenführung für den Räumschild vorgesehen ist, welche Seitenführung wenigstens einen um eine stehende Achse umlaufenden Führungskörper aufweist.The invention solves this problem in that provided over the side edge of the plow blade protruding side guide for the plow blade is, which side guide has at least one about a stationary axis rotating guide body.

Durch das Vorsehen der über den Seitenrand des Räumschildes hinausragenden Seitenführung kann ein direkter Kontakt zwischen Räumschild und Leitschiene, Leitwand oder einem anderen im Seitenbereich der Fahrbahn befindlichen Objekt sicher vermieden werden, wobei der wenigstens eine um eine stehende Achse umlaufende Führungskörper der Seitenführung dafür sorgt, daß sich der Führungskörper an Leitschiene, Leitwand oder Objekt abwälzt, wodurch Beschädigungen derselben unterbunden werden.By providing the over the side edge of the plow blade protruding side guide direct contact between plow blade and guardrail, baffle or another located in the side region of the road object can be safely avoided, the at least one circumferential axis about a stationary guide body of the side guide ensures that the guide body rolls on guide rail, baffle or object, whereby damage to the same can be prevented.

Um die Seitenführung bei Nichtbedarf nicht in aufwendiger Weise vom Räumschild bzw. Schneepflug abmontieren zu müssen, empfiehlt es sich, wenn der Führungskörper mittels einer Stelleinrichtung aus der über den Seitenrand des Räumschildes vorstehenden Arbeitsstellung in eine Ruhestellung hinter den Seitenrand des Räumschildes verlagerbar ist. Der Antrieb hierfür kann beispielsweise hydraulisch, pneumatisch oder elektromechanisch erfolgen.In order not to have to disassemble the side guide when not needed in a complex manner from the ploughshare or snow plow, it is recommended that the guide body is displaceable by means of an adjusting device from the above the side edge of the plow blade above working position in a rest position behind the side edge of the plow blade. The drive for this can be done for example hydraulically, pneumatically or electromechanically.

Zum Anpassen der Höhenlage der Seitenführung empfiehlt es sich, wenn der Führungskörper gegenüber dem Räumschild der Höhe nach verstellbar gelagert ist, wodurch die Seitenführung beispielsweise exakt an die Höhenlage einer Leitschiene od. dgl. einstellbar ist.To adjust the altitude of the side guide, it is recommended that the guide body relative to the dozer blade height is adjustable, whereby the side guide, for example, exactly to the altitude of a guide rail od. Like. Is adjustable.

Besonders einfache Konstruktionsverhältnisse ergeben sich, wenn der Führungskörper aus einer Führungsrolle besteht, die beispielsweise eine PVC-Walze oder eine gummierte Stahlwalze sein kann. Es besteht aber auch die Möglichkeit, mehrere Laufrollen in Achsrichtung übereinander oder in Räumrichtung hintereinander anzuordnen. Sind bei besonders schweren Räumfahrzeugen sehr große Kräfte abzutragen, kann als Führungskörper auch eine gegebenenfalls antreibbare Raupenkette vorgesehen sein, die sich über mehrere Laufrollen am Räumschild abstützt. Daß sämtliche, die Erfindung betreffenden umlaufenden Führungskörper bei Bedarf drehangetrieben werden können, versteht sich von selbst.Particularly simple construction conditions arise when the guide body consists of a guide roller, which may be, for example, a PVC roller or a rubberized steel roller. But it is also possible to arrange several rollers in the axial direction one above the other or in the clearing direction one behind the other. If very heavy forces are to be removed in the case of particularly heavy clearing vehicles, it is also possible to provide as a guide body an optionally drivable track chain which is supported on the clearing blade over several rollers. It goes without saying that all rotating guide bodies, which concern the invention, can be rotated when required.

Um eine starre Verbindung zwischen Räumschild und Leitschiene, Leitwand od. dgl. zu vermeiden, bzw. um Stöße kompensieren bzw. dämpfen zu können, empfiehlt es sich, wenn der Führungskörper in einem in Richtung der Arbeitsbreite des Räumschildes federnd abgestützten Lager gehalten ist. Durch diese Maßnahme werden übermäßige, in der Folge von Stößen auf Räumschild oder Objekt einwirkende Kräfte vermieden, die wiederum zu Beschädigungen führen könnten.In order to avoid a rigid connection between plow blade and guide rail, baffle od. Like., Or to compensate for shocks or to be able to dampen, it is recommended that the guide body is held in a resiliently supported in the direction of the working width of the plow blade bearing. This measure avoids excessive forces acting on the plow blade or object as a result of impact, which in turn could lead to damage.

Zudem kann für den Führungskörper ein um eine in Fahrtrichtung verlaufende Achse begrenzt verschwenkbares Lager vorgesehen sein, wodurch gewährleistet ist, daß der Führungskörper stets mit einer größtmöglichen Auflagefläche von dem gewünschten Objekt ferngehalten wird und wodurch Flächenpressungskräfte zwischen Führungskörper und Objekt minimal gehalten werden.In addition, a limited pivotable about an axis extending in the direction of travel pivot bearing can be provided for the guide body, which ensures that the guide body is always kept away with a maximum contact surface of the desired object and which surface pressure forces between the guide body and object are kept minimal.
