Vorrichtung zur Befestigung eines Arbeitsgerätes an einemDevice for attaching an implement to a
Fahrzeugvehicle
Die Erfindung betrifft eine "Vorrichtung zur Befesti¬ gung eines Arbeitsgerätes, z.B. der Schar eines Schnee¬ pfluges, an einem Fahrzeug, mit einem am Fahrzeug um eine waagrechte, quer zur Fahrzeuglängsrichtung verlaufende Hauptachse verschwenkbaren Grundrahmen, der an seinemThe invention relates to a "device for Befesti¬ supply of a working device, for example of the blade of a Schnee¬ plow, to a vehicle, with a pivotable on the vehicle about a horizontal, transverse to the vehicle longitudinal direction of the main axis of the base frame, at its
Vorderende, z.B. mittels eines Kugelgelenkes, das Arbeits¬ gerät trägt, wobei die üblichen zur Einstellung der Ar¬ beitslage des Arbeitsgerätes um die lotrecht und die ho¬ rizontal, parallel und quer zur Fahrzeuglängsrichtung verlaufenden Achsen vorgesehenen hydraulischen Zylinder unmittelbar am Arbeitsgerät angreifen.Front end, e.g. by means of a ball-and-socket joint which carries the implement, the customary hydraulic cylinders provided for adjusting the working position of the implement about the perpendicular and horizontal axes parallel and transverse to the longitudinal direction of the vehicle acting directly on the implement.
Vorrichtungen dieser Art weisen den Nachteil auf, daß jede Betätigung eines hydraulischen Zylinders eine allgemeine Bewegung des Schildes herbeiführt. Es ist also, ausgenommen'die reine Höhenverstellung, nicht möglich, die Neigung des Schildes um eine lotrechte Achse zu än¬ dern, ohne daß gleichzeitig auch die Höhe und die Nei¬ gung um eine waagrechte Achse verändert wird.Devices of this type have the disadvantage that each actuation of a hydraulic cylinder causes a general movement of the shield. It is thus excluded 'pure height adjustment, not possible countries the slope of the blade about a vertical axis to än¬ without simultaneously also the height and the Nei¬ is used to alter about a horizontal axis.
Andere Vorrichtungen, die Bewegungen der Bearbei- tungseinrichtungen um drei aufeinander senkrecht stehenden Raumachsen zulassen, sind ebenfalls bekannt. Um die er¬ heblichen Kräfte vom Fahrzeug auf das Bearbeitungsgerät zu übertragen, ist es jedoch nötig, schwere Rahmenkon¬ struktionen vorzusehen. Neben den hohen Produktionskosten wirkt sich das Gewicht der Einrichtung besonders negativ auf die Schwerpunktlage des Fahrzeuges aus.Other devices are known which allow the machining devices to move about three mutually perpendicular spatial axes. In order to transmit the considerable forces from the vehicle to the processing device, however, it is necessary to provide heavy frame structures. In addition to the high production costs, the weight of the device has a particularly negative effect on the center of gravity of the vehicle.
