Description

Die vorliegende Erfindung betrifft eine Schneefräse mit mindestens einem walzenförmigen Fräskörper, der mit einer Antriebseinheit verbunden und mittels zweier ihn seitlich einfassender Lagerelemente um eine horizontale Achse drehbar an einem Rahmen gelagert ist.The present invention relates to a snow blower at least one cylindrical milling body that with connected to a drive unit and by means of two him lateral bearing elements around a horizontal Axle is rotatably mounted on a frame.

Schneefräsen der vorstehend angegebenen Art sind in verschiedenen Ausführungen bekannt, beispielsweise aus den deutschen Offenlegungsschriften 3720158, 3304654, 2914338 und 19821052 sowie den US-Patenten 4255879 und 4457086 und der österreichischen Patentschrift 320008. Der Antrieb für den Fräskörper kann dabei mehr oder weniger mittig auf den Fräskörper wirken (z. B. DE-OS 3720158) oder aber außerhalb eines der beiden Lagerelemente an einem Achsstummel des Fräskörpers angreifen (z. B. DE-OS 3304654).Snow blowers of the type specified above are in various designs known, for example from German Offenlegungsschriften 3720158, 3304654, 2914338 and 19821052, and U.S. Patents 4,255,879 and 4457086 and the Austrian patent specification 320008. The drive for the milling body can do more or act less centrally on the milling body (e.g. DE-OS 3720158) or outside one of the two bearing elements attack on a stub axle of the milling body (e.g. DE-OS 3304654).

Unabhängig davon, welches Antriebskonzept gewählt wird, leiden Schneefräsen der gattungsgemäßen Art unter dem Nachteil, daß sie bei weichem Schnee nur bedingt und bei härterem und hartem Schnee nahezu überhaupt nicht lenkbar sind.Regardless of which drive concept is chosen, snow blowers of the generic type suffer from the Disadvantage that they are only conditional and soft snow with hard and hard snow almost not at all are steerable.

Neben Schneefräsen der gattungsgemäßen Art sind auch solche bekannt, bei denen der Fräskörper nicht seitlich gelagert ist sondern vielmehr mittig, insbesondere im Bereich eines Getriebes. Die beiden Abschnitte des Fräskörpers kragen dabei frei über die Lagerung aus. Dies bedarf einer technisch aufwendigen, teuren und schweren Ausführung der Lagerung. In addition to snow blowers of the generic type are also those known in which the milling body is not laterally is stored but rather in the middle, especially in Area of a transmission. The two sections of the The milling body protrudes freely over the bearing. This requires a technically complex, expensive and heavy execution of storage.

Aus den vorstehend dargelegten Nachteilen des Standes der Technik leitet sich die der vorliegenden Erfindung zugrundeliegende Aufgabenstellung ab, die darin besteht, eine Schneefräse der eingangs genannten Art zu schaffen, die sich gegenüber bekannten gattungsgemäßen Schneefräsen durch eine besonders gute Lenkbarkeit auszeichnet.From the disadvantages of the state set out above The technique derives from that of the present invention underlying task from that in it there is a snow blower of the type mentioned at the beginning create that compared to known generic Snow blowers through particularly good maneuverability distinguished.

Gemäß der vorliegenden Erfindung wird diese Aufgabe dadurch gelöst, daß mit dem Fräskörper mindestens eine seitlich außerhalb eines Lagerelements angeordnete Freischneideinrichtung drehfest verbunden ist. Bei der erfindungsgemäßen Schneefräse ist somit ergänzend zu dem mindestens einen Fräskörper mindestens eine Freischneideinrichtung vorgesehen, die außerhalb eines Lagerelements angeordnet ist und mit dem zugeordneten Fräskörper drehfest verbunden ist, insbesondere über einen durch das betreffende Lagerelement hindurchtretenden Wellenzapfen des Fräskörpers.According to the present invention, this object solved in that with the milling body at least one arranged laterally outside of a bearing element Brush cutter is non-rotatably connected. In the snow blower according to the invention is thus also supplementary the at least one milling body at least one Brush cutter provided outside of a Bearing element is arranged and associated with Milling body is rotatably connected, in particular via one passing through the bearing element in question Shaft journal of the milling body.

Bereits bei einer vergleichsweise geringen axialen Erstreckung der Freischneideinrichtung von ca. 10 cm zeichnet sich die erfindungsgemäße Schneefräse durch eine überragende Lenkbarkeit aus. Einer Verstärkung der Lagerelemente gegenüber denen gattungsgemäßer Schneefräsen bedarf es dabei nicht.Even with a comparatively small axial Extension of the brush cutter by approx. 10 cm is characterized by the snow blower according to the invention outstanding maneuverability. A reinforcement of the Bearing elements compared to those of generic snow blowers it is not necessary.

Wenngleich sich bereits eine Freischneideinrichtung, deren Durchmesser erheblich geringer ist als der Durchmesser des Fräskörpers, positiv auf die Lenkbarkeit der Schneefräse auswirkt, so entspricht doch gemäß einer bevorzugten Weiterbildung der Erfindung der Durchmesser der mindestens einen Freischneideinrichtung im wesentlichen dem Durchmesser des Fräskörpers. Er kann in Sonderfällen sogar Letzteren überschreiten.Although there is already a brush cutter, whose diameter is considerably smaller than the diameter of the milling body, positive on the steerability of the Snow blower affects, according to one preferred development of the invention of the diameter the at least one brush cutter essentially the diameter of the milling body. He can in Special cases even exceed the latter.

Gemäß einer anderen bevorzugten Weiterbildung ist die mindestens eine Freischneideinrichtung auf einen durch das benachbarte Lagerelement durchtretenden Wellenzapfen des Fräskörpers aufsteckbar. Dies ermöglicht einen Austausch der Freischneideinrichtung mit geringstem Aufwand. Dies hinwiederum gestattet beispielsweise die Freischneideinrichtung als Verschleißteil auszuführen, das in regelmäßigen Abständen zu erneuern ist. Als drehfeste Verbindung der Freischneideinrichtung mit dem Wellenzapfen des Fräskörpers kommt dabei beispielsweise ein Keilwellenprofil in Betracht.According to another preferred development, the at least one brush cutter on one the shaft bearing passing through the adjacent bearing element of the milling body attachable. this makes possible an exchange of the brush cutter with the least Expenditure. This in turn allows for example to design the brush cutter as a wearing part, which must be renewed at regular intervals. As a non-rotatable connection of the brush cutter with The shaft journal of the milling body comes for example consider a spline profile.

Im Rahmen der vorliegenden Erfindung kann die mindestens eine Freischneideinrichtung über einen Teil ihres Umfangs von einer auch den Fräskörper teilweise abdeckenden Schneeführung abgedeckt sein. Bei dieser Weiterbildung der Erfindung wird auch der von der Freischneideinrichtung erfaßte Schnee dem Auswurf zugeführt und aus dem Fräsbereich entfernt. Späteres Nachrutschen des durch die Freischneideinrichtung aufgelockerten Schnees in den Fräsbereich wird auf diese Weise unterbunden.In the context of the present invention, the at least one brush cutter over a part their circumference of one also partially the milling body covering snow guide. At this Further development of the invention is also that of Brush cutter detects snow that is ejected and removed from the milling area. Later Slipping through the brush cutter loosened snow in the milling area is on prevented this way.

Gemäß einer wiederum anderen bevorzugten Weiterbildung der Erfindung weist die Freischneideinrichtung im Bereich ihrer freien Stirnseite mindestens einen Ring auf. Besonders bevorzugt sind zwei derartige Ringe konzentrisch zueinander angeordnet. Der mindestens eine stirnseitige Ring der Freischneideinrichtung trägt zur Unfallverhütung bei, ohne dabei die Lenkbarkeit der Schneefräse allzu sehr zu beeinträchtigen. According to yet another preferred development the invention has the brush cutter in Area of their free end face at least one ring on. Two such rings are particularly preferred arranged concentrically to each other. The at least one front ring of the brush cutter contributes to Accident prevention without sacrificing the manageability of the Impact snow blower too much.
