Description

Die Erfindung betrifft eine Schneefräse mit mindestens einer im inneren der Frästrommel angeordneten Antriebseinheit.The invention relates to a snow blower with at least a drive unit arranged inside the milling drum.

Eine für den Hausgebrauch geschaffene, bekannte Schneefräse dieser Art (ueutsche Offenlegungsschrift 1 459 656) weist im Inneren der Frästrommel einen Elektromotor auf, wobei für den vorgesehenen Verwendungszweck eine Drehzahl- oder Drehmomentenregelung nicht vorgesehen ist.A well-known snow blower of this type created for household use (German Offenlegungsschrift 1 459 656) has an electric motor inside the milling drum, whereby for the intended purpose speed or torque control is not provided.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, Schneefräsen der in Frage stehenden Art so weiterzuentwickeln, daß sie hinsichtlich ihres Antriebs an die jeweiligen Schnee-erhältnisse angepaßt werden können.In contrast, the invention is based on the object of snow blowers of the type in question to be further developed in such a way that their drive is adapted to the respective snow conditions can be.

Erfindungsgemäß wird zur Losung dieser Aufgabe vorgeschlagen, daß mindestens zwei wahlweise zu- oder abschaltbare hydraulische Antriebseinheiten vorgesehen sind. Die Verwendung einer Mehrzahl solcher Antriebseinheiten ermöglicht deren Anpassung in Drehzahl und Drehmoment an die herrschenden Schneeverhältnisse; bei während des Geräteein- »atzes häufig veränderlichen Schneeverhältnissen ist es dadurch möglich, beispielsweise bei lockeren Schnecschichten mit hoher Drehzahl und geringerem Drehmoment, hingegen bei durch Sonneneinwirkung verdichteten Schneeschichten bei geringerer Drehzahl mit größerem Drehmoment zu arbeiten. Durch die Auflösung des Antriebsaggregats in mehrere Einheiten wird aber zugleich der Vorteil erzielt, daß diese sich besser im Inneren der Frästrommcl unterbringen lassen.According to the invention it is proposed to solve this problem that at least two optionally available or disconnectable hydraulic drive units are provided. The use of a plural Such drive units enable their speed and torque to be adapted to the prevailing Snow conditions; when the snow conditions »frequently change while the device is in use this makes it possible, for example with loose layers of snow at high speed and lower Torque, on the other hand in the case of layers of snow compacted by the action of the sun at a lower speed to work with greater torque. By breaking up the drive unit into several units but at the same time the advantage is achieved that these can better accommodate themselves inside the Frästrommcl leave.

Die erfindungsgemäß vorgeschlagene Schaltung der hydraulischen Antriebseinheiten kann auch zur Steuerung der Wurfweite des ausgeworfenen Schnees eingesetzt werden. Bei Abschaltung einer Antriebseinheit kann mit der gleichen Menge an Hydraulikflüssigkeit eine sehr hohe Drehzahl der angeschalteten Antriebseinheit, also ein weiter Wurf der Schneemassen erzielt werden; umgekehrt kann bei Betrieb beider Antriebseinheiten, bei welchem diese mit der gleichen Menge an Hydraulikflüssigkeit langsamer drehen, eine niedrigere Drehzahl der Antriebseinheiten und damit ein kurzer Wurf der Schneemassen bei hoher Förderleistung erzielt werden.The circuit of the hydraulic drive units proposed according to the invention can also be used for Control of the throwing distance of the thrown snow can be used. When switching off a drive unit can achieve a very high speed of the switched on with the same amount of hydraulic fluid Drive unit, so a further throw of the snow masses can be achieved; vice versa when operating both drive units, in which they are slower with the same amount of hydraulic fluid turn, a lower speed of the drive units and thus a short throw of the snow masses high delivery rate can be achieved.

Eine zweckmäßige Ausführungsform besteht darin, daß die Antriebseinheiten jeweils auf ein allen oder mehreren Antriebseinheiten gemeinsames mit der Welle der Frästrommel drehfest verbundenes Antriebszahnrad treiben. Dadurch wird der bauliche Aufwand verkleinert.An expedient embodiment is that the drive units are each on all or several drive units that are jointly connected to the shaft of the milling drum in a rotationally fixed manner Drive drive gear. This reduces the structural effort.

Eine Ausführungsform der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Fig. 1 zeigt die Vorderansicht einer Schneefräse mit aufgeschnittener Frästrommel undFig. 1 shows the front view of a snow blower with a cut-open milling drum and

Fig. 2 einen Schnitt gemäß H-II der Fig. 1 in vergrößerier Darstellung.FIG. 2 shows a section according to H-II of FIG. 1 in enlarged view.

F i a. 1 zeiet eine Schneefräse 1, deren Frästrommel 3 in einem mittleren Bereich aufgeschnitten ist. Im Inneren der Frästrommel erkennt man die Welle 4 der Frästrommel. Auf der Welic4 sitzt das Antriebszahnrad 5. Mit dem Antriebszahnrad kämmen die Antriebsritzel 6 der beiden hydraulischen Antriebseinheifv.n 7 und 8.F i a. 1 shows a snow blower 1, its milling drum 3 is cut open in a central area. You can see them inside the milling drum Shaft 4 of the milling drum. That sits on the Welic4 Drive gear 5. The drive pinions 6 of the two hydraulic ones mesh with the drive gear Drive units 7 and 8.

Aus Fig. 2 ist ersichtlich, daß die hydraulischen Antriebseinheiten 7 und 8 diametral gegenüberliegend am Antriebszahnrad 5 angeordnet sind. Im Zentrum des Antriebszahnrads 5 ist die als HoIiI-welle ausgebildete Welle 4 der Frästrommel gezeigt. 9 und 10 sind Ventile bzw. Hähne zum Steuern des Druckmittelkreislaufs. In den Hahn 10 mündet die zentrale Hochdruckleitung Π. Der Hahn 10 verteilt das Öl über die zwei Arme 12 und 13 in die bciden hydraulischen Antriebseinlieiten 8 und 7. Gegenüberliegend an den hydraulischen Antriebseinlieilen ist über die Leitungsarme 14 und 15 die zentrale RücklauHeiiung 16 über den Hahn 9 angeschlossen. In dem gezeigten Ausführungsbeispiel sind die hydraulischen Antriebscinheiten also parallel geschaltet. Die Hähne 9 und 10 können als Mehrwegventile ausgebildet sein, derart, daß jeder der h\draulischen Antriebseinheiten auch allein betrieben werden kann. Dadurch ist eine einfache Steuerung des Drehmoments bzw. der Drehzahl der Frästrommel möglich. Dabei ist es zweckmäßig, die Mehrwegventile vom Fahrerhaus des Fahrzeues 2 aus zu steuern.From Fig. 2 it can be seen that the hydraulic drive units 7 and 8 are diametrically opposite are arranged on the drive gear 5. In the center of the drive gear 5 is called the HoIiI-shaft formed shaft 4 of the milling drum is shown. 9 and 10 are valves and cocks for controlling of the pressure medium circuit. The central high pressure line Π opens into the cock 10. The cock 10 distributed the oil via the two arms 12 and 13 into the two hydraulic drive units 8 and 7. Opposite on the hydraulic drive units the central return line 16 is connected via the tap 9 via the line arms 14 and 15. In the embodiment shown, the hydraulic Drive units connected in parallel. The taps 9 and 10 can be used as multi-way valves be designed in such a way that each of the hydraulic Drive units can also be operated alone. This makes it easy to control the torque or the speed of the milling drum is possible. It is advisable to use the multi-way valves from To control the driver's cab of the vehicle 2.
