Description
ZUSATZANWELDUNG Straßenfräse Das Hauptpatent (Aktenzeichen P 16 58 559.4) betrifft eine Straßenfräse mit einem auf vorzugsweise vier Rädern laufenden Rahmenteil und einem daran verstellbar aufgehängten, eine motorgetriebene Fräswelle tragenden Frästisch, wobei zwei in Fahrtrichtung hintereinander liegende, gegenläufige Fräswellen vorgesehen sind.ADDITIONAL APPLICATION Road milling machine The main patent (file number P 16 58 559.4) relates to a road milling machine with one that runs on preferably four wheels Frame part and an adjustable, motor-driven milling shaft suspended from it load-bearing router table, with two opposite one another in the direction of travel Milling shafts are provided.
Die Anordnung zweier gegenläufiger, hintereinander liegender Fräswellen hat, wie bereits in der Hauptanmeldunf ausgeführt worden ist, den Vorteil, daß sich die Schubwirkungen der Fräswerkzeuge auf den beiden Fräswellen in Bezug auf das Fahrgestell aufheben und nahezu keinen Einfluß auff die Fahrbewegung der arbeitenden Straßenfräse haben. Auf diese Weise kann mit relativ geringer Fahrabtriebsleistung auch an steilen Straßenstükken gearbeitet werden.The arrangement of two milling shafts running in opposite directions one behind the other has, as has already been stated in the main application, the advantage that the thrust effects of the milling tools on the two milling shafts in relation to the Raise the chassis and have almost no influence on the movement of the workers Have road milling machine. In this way, with relatively little power output also work on steep stretches of road.
Die bei einer Straßenfräse gemäß der Hauptanmeldung verwendeten Lamellenfräsringe sind besonders zum Abfräsen von Markierungen oder eines Gummibelags auf Landepisten von Flugzeugen geeignet; große Fräsringe weisen jedoch bei Fräsarbeiten an schwierigerem Untergrund gewisse Nachteile auf. Um eine Straßenfräse gemäß dem Hauptpatent auch für derartige schwere Fräsarbeiten verwenden zu können, wird gemäß vorliegender Erfindung vorgeschlagen, daß auf die Fräswellen Fräswalzen aufgebracht sind, die mit schraubenartig um den Walzenkörper angeordneten Hartmetallmeißeln bestückt sind.The lamellar milling rings used in a road milling machine according to the main application are especially for milling off markings or a rubber covering on runways suitable for aircraft; However, large milling rings point to more difficult milling work Underground has certain disadvantages. To a road milling machine according to the main patent too to be able to use it for such heavy milling work, according to the present Invention proposed that the milling drums are applied to the milling shafts are equipped with hard metal chisels arranged helically around the roller body.
Die in Fahrtrichtung der Straßenfräse hintere Fräswalze soll dabei wesentlich nehr Meißel aufweisen, als die ir; wesentlichen nur zum Vorfräsen dienende vordere Fräswalze. Besonders günstige Ergebnisse ergeben sich, wenn die Meißel auf der vorderen Fräswalze in Form einer einfachen Linksschraube und auf der hinteren Fräswalze in Form einer dreifachen Rechtsschraube angeordnet sind.The milling drum at the rear in the direction of travel of the road milling machine should be used have considerably more chisels than the ir; essential only for rough milling front milling drum. Particularly favorable results are obtained when the chisel is on the front milling drum in the form of a simple left-hand screw and on the rear Milling drum are arranged in the form of a triple right-hand screw.
Um die Fräswalzen in ihre Eingriffsstellung und aus dieser heraus bewegen zu können, was insbesondere zur Herstellung von Markierungen notwendig ist, sind die Fräswellen mit den Präswalzen vorteilhafterweise über Schwinghebel verstellbar, wobei zur unabhängigen Verstellung der Frästiefe der vorderen und hinteren Wellen zusätzliche, den Frästisch verstellende Schraubanschläge vorgesehen sind.Around the milling drums in and out of their engagement position to be able to move, which is particularly necessary for the production of markings, the milling shafts with the embossing rollers are advantageously adjustable via rocker arms, whereby for independent adjustment of the milling depth of the front and rear shafts additional screw stops that adjust the router table are provided.
Anliand des in den Figuren der Zeichnung schematisch dargestellten Ausführungsbeispiels soll die Erfindung nachstehend mit weiteren Merkmalen näher erläutert werden. Dabei zeigt: Fig. 1 eine schematische Seitenansicht einer erfindungsgemäßen Straßenfräse, Fig. 2 und 3 seitliche Ansichten und. Schnittdarstellungen der vorderen und. hinteren Fräsenwalzen zur Verdeutlichung der Anordnung der Meißel.Anliand of the shown schematically in the figures of the drawing Exemplary embodiment, the invention is to be described in more detail below with further features explained. 1 shows a schematic side view of an inventive Road milling machine, Fig. 2 and 3 side views and. Sectional views the front and. rear milling rollers to illustrate the arrangement of the chisels.
Die erfindungsgemäße Straßenfräse läuft auf vier Rädern und ist mit einem Dieselmotor, einen Vorscllubaggregat, einen Propangasbrenner und. zwei gegenläufigen Fräswellen 1 versehen, deren Frästiefe verstellt werden kann. Das Vorschubaggregat und der Propangasbrenner sind dabei der Übersichtlichkeit lialber nicht mit eingezeichnet worden, der Dieselmotor ist schematisch angedeutet und nit 10 bezeichnet. Das Verstellen der Prästiefc erfolgt über eine, durch ein Speichenrad 12 betätigbare Spindel 2, die den an den Schwinghebeln 4 aufgehängten Fräsentisch 3 bewegt. Die Schwinghebel 4 bilden an jeder Längsseite ein Parallelogramm und eine Aufhängung für den Frästisch - der sämtliche Aggregate trägt -an dem Rahmenteil 7. Durch Schraubanschläge 5 wird die gewünschte Tiefe eingestellt.The road milling machine according to the invention runs on four wheels and is with a diesel engine, a preclub unit, a propane gas burner and. two counter-rotating Milling shafts 1 provided, the milling depth of which can be adjusted. The feed unit and the propane gas burner are not shown for the sake of clarity has been, the diesel engine is indicated schematically and designated nit 10. The adjustment the Prästiefc takes place via a spindle 2, which can be actuated by a spoked wheel 12, which moves the milling table 3 suspended on the rocking levers 4. The rocker arm 4 form a parallelogram and a suspension for the router table on each long side - which carries all the units - on the frame part 7. By screw stops 5 is set the desired depth.
Die beiden Fräswalzen 14 und 16 sind mit Fräsmeißen 15 bestückt, die schraubenartig um den Walzenkörper angeordnet sind, wobei die Meißel auf der vorderen Fräswalze 14 (Fig. 3) in Form einer einfachen Linksschraube und auf der hinteren Fräswalze 16 (Fig. 2) in Fern einer dreifachen Rechtsschraube angeordnet sind. Durch diese Anordnung der Meißel und durch die gegenläufige Drehrichtung der Fräswalzen ist es möglich, in einem Durchgang eine Straßendecke in einer Tiefe bis zu 30 mm abzufräsen. Dabei reißt die vordere Fräswalze die Decke bis zu einer Tiefe von etwa 20 mm auf; die hintere Fräswalze fräst die Decke anschließend auf eine Tiefe von 30 mm aus und glättet sie. Da die vordere Fräswalze gegen den Vorschub fräst und die hintere mit dem Vorschub, ist es mit einer relativ geringen Achsenlast und einem relativ kleinen Vorschubgetriebe möglich, auch Strassen, die große Steigungen aufweisen, abzufräsen; die hohen Fräswiderstände heben sich durch die gegenläufige Drehrichtung der Fräswellen praktisch auf.The two milling drums 14 and 16 are equipped with milling cutters 15, which are arranged helically around the roller body, with the chisel on the front Milling drum 14 (Fig. 3) in the form of a simple left-hand screw and on the rear Milling drum 16 (Fig. 2) are arranged in the distance of a triple right-hand screw. By this arrangement of the chisels and the opposite direction of rotation of the milling drums it is possible to build a road surface with a depth of up to 30 mm in one pass to mill off. The front milling drum tears the ceiling to a depth of about 20 mm on; the rear milling drum then mills the ceiling to a depth of 30 mm and smooths them. Since the front milling drum mills against the feed and the rear with the feed, it is with a relatively low axle load and one relatively small feed gears possible, even roads with steep inclines, to mill off; the high Milling resistances are offset by the opposite Direction of rotation of the milling shafts practically on.
