Description
Die Erfindung betrifft ein selbstfahrendes Gerät zum Abfräsen von Verkehrsflächen nach dem Oberbegriff des Anspruchs 1.The The invention relates to a self-propelled device for milling traffic areas the preamble of claim 1.
Bei kleinen Geräten zum Abfräsen von Verkehrsflächen, sogenannten Kompaktfräsen, ist üblicherweise das Fräswerk mit einer Geräteseite bündig angeordnet und zur gegenüberliegenden Geräteseite beabstandet, da es eine im Vergleich zur Gerätebreite relative geringe Breite, die beispielweise der halben Gerätebreite entspricht, aufweist. Dementsprechend ist der Kraftangriff auf das Gerät weit aus der Mitte versetzt. Durch diesen Versatz entsteht ein Moment um die Hochachse des Geräts. Dieses führt dazu, daß das Gerät dazu neigt, beim Fräsvorgang aus der Spur gedrückt zu werden. Dies kann man durch ständiges Gegenlenken ausgleichen. Allerdings führt dies zu einem entsprechenden Bedienaufwand und Reifenverschleiß.at small devices for milling of traffic areas, so-called compact milling, is usually the milling machine with a device side arranged flush and to the opposite Device side spaced, as it is one in comparison to the device width relatively small width, for example, half the width of the device corresponds, has. Accordingly, the force attack on the Device far offset from the middle. This offset creates a moment around the vertical axis of the device. This leads that the Device to do so tends, during the milling process pushed out of the track to become. This can be compensated by constant counter-steering. However, this leads to a corresponding operating effort and tire wear.
Ferner ist es bekannt, dieses Problem dadurch zu mildern, daß man ein ausklappbares Hinterrad an der Seite, an der das Fräswerk bündig zur Geräteseite angeordnet ist, mit einem relativ großen Ausklapphebel vorsieht, so daß sich dadurch bei ausgeklapptem Hinterrad das Fräswerk mehr mittig zwischen den Hinterrädern befindet. Abgesehen davon, daß dies zu einer entsprechenden Breite des Geräts führt, kann nicht immer mit ausgeklapptem Hinterrad gearbeitet werden. Wenn benachbart zu Bordsteinen zu fräsen ist, geht dies nur mit eingeklapptem Hinterrad, so daß dann das Problem, daß das Gerät dazu neigt, aus der Spur gedrückt zu werden, weiterhin besteht.Further It is known to alleviate this problem by having one foldable rear wheel on the side, at which the milling machine is flush with the device side is arranged with a relatively large folding lever, so that thereby, with the rear wheel unfolded, the milling machine is more centered between the rear wheels located. Apart from that, this leads to a corresponding width of the device, can not always with unfolded Rear wheel to be worked. When milling adjacent to curbs, this is only possible with the rear wheel folded in, so that then the problem that the device tends pushed out of the track to continue to exist.
Aufgabe der Erfindung ist es, ein Gerät zum Abfräsen von Verkehrsflächen zu schaffen, bei dem die Neigung des Geräts, beim Fräsvorgang aus der Spur gedrückt zu werden, in einfacher Weise zumindest wesentlich herabgesetzt oder eliminiert ist.task The invention is a device for milling of traffic areas in which the tendency of the device to be pushed out of the way during the milling process, in a simple way at least significantly reduced or eliminated is.
Diese Aufgabe wird entsprechend den Merkmalen des Anspruchs 1 gelöst.These The object is achieved according to the features of claim 1.
Die Erfindung betrifft daher ein selbstfahrendes Gerät zum Abfräsen von Verkehrsflächen mit einem höhenverstellbaren Chassis, das ein lenkbares Fahrwerk mit einem vorderen und einem hinteren Paar von Rädern mit Einzelradantrieben und ein Antriebsaggregat hierfür und zum Antreiben eines mit dem Antriebsaggregat gekoppelten Fräswerks trägt, das eine Fräswalze und ein Fräsgetriebe hierfür umfaßt, wobei sich die Fräswalze quer zur Fahrtrichtung erstreckt, eine Breite geringer als die Gerätebreite aufweist und außermittig zum Gerät angeordnet ist, wobei die Traktion mindestens eines Rades entsprechend einer wenigstens teilweisen Kompensation des beim Fräsen um die Hochachse des Geräts wirkenden Moments geändert ist. Hierdurch kann somit eine Verteilung der Zugkräfte auf die einzelnen Räder vorgegeben werden, und zwar derart, daß das beim Fräsvorgang erzeugte Moment um die Hochachse der Maschine wenigstens teilweise kompensiert und der Geradeauslauf des Geräts auch bei hohen Fräslasten entsprechend verbessert ist.The The invention therefore relates to a self-propelled device for milling traffic areas a height-adjustable Chassis, which has a steerable landing gear with a front and a rear pair of wheels with Einzelradantrieben and a drive unit for this and the Driving a coupled to the drive unit carries milling machine, the a milling drum and a milling gear therefor comprises with the milling drum extends transversely to the direction of travel, has a width less than the device width and off-center to the device is arranged, wherein the traction of at least one wheel accordingly an at least partial compensation of the milling around the Vertical axis of the device changed effective moments is. This allows a distribution of tensile forces given the individual wheels be such that the during the milling process generated moment about the vertical axis of the machine at least partially compensated and the straight-line stability of the device even at high milling loads is improved accordingly.
Insbesondere ergibt sich eine sehr einfache Lösung, wenn wenigstens einer der Einzelradantriebe, parallel geschaltete, hydraulische Axialkolbenmotoren, eine Verstelleinrichtung für die Traktion des zugehörigen Rades aufweist, mit der die Verteilung der Zugkräfte entsprechend einer wenigstens teilweisen Kompensation des beim Fräsen um die Hochachse des Geräts wirkenden Moments beeinflußt wird.Especially results in a very simple solution if at least one of the single-wheel drives, connected in parallel, Hydraulic axial piston motors, an adjustment device for traction of the associated Rades, with the distribution of tensile forces according to at least one partial compensation of the milling around the vertical axis of the device Moments is affected.
Jedoch ist auch möglich, daß mindestens ein Einzelradantrieb an einer Seite des Geräts ein Getriebe mit einer Übersetzung aufweist, die zu einer wenigstens teilweisen Kompensation des beim Fräsen um die Hochachse des Geräts wirkenden Moments gegenüber den Übersetzungen von Getrieben von mindestens zwei Einzelradantrieben von Rädern an der anderen Seite des Geräts unterschiedlich ist, oder daß mindestens ein Raddurchmesser an einer Seite des Geräts zu einer wenigstens teilweisen Kompensation des beim Fräsen um die Hochachse des Geräts wirkenden Moments gegenüber den Raddurchmessern von Rädern auf der anderen Seite des Geräts unterschiedlich ist. Allerdings bleibt in diesen Fällen die unterschiedliche Traktion der Räder beim Transportgang des Geräts erhalten, so daß bei diesem der Geradeauslauf beeinträchtigt wird. Da allgemein die vom Gerät zurückzulegenden Transportstrecken jedoch gering sind, ist dies von untergeordneter Bedeutung.however is possible, too, that at least a single-wheel drive on one side of the unit a gearbox with a translation which leads to an at least partial compensation of the mill around the vertical axis of the device opposite to acting moments the translations of transmissions of at least two single wheel drives of wheels the other side of the device is different, or that at least a wheel diameter on one side of the device for at least partial compensation when milling around the vertical axis of the device opposite to acting moments the wheel diameters of wheels on the other side of the device is different. However, in these cases, the different traction of the wheels during transport of the device received so that at this affects the straight-line stability becomes. As generally the device to be covered Transport routes are low, this is of minor importance Importance.
