Description
Blockiereinric-htung für Pendelachsen an Fahrzeugen aller Art insbesondere Baggern und Kranen Allgemeines : Es sind Blockiereinrichtungen für Pendelachsen an oben genannten Fahrzeugen bekannte die mit mechanischen oder hydraulischen Mitteln eine Blockierung der pendelnd aufgehängten Starrachse erreichen.Blocking device for swing axles on vehicles of all kinds, in particular Excavators and cranes General: They are blocking devices for pendulum axles known on the above-mentioned vehicles using mechanical or hydraulic means achieve a blockage of the pendularly suspended rigid axle.
. Diese bekannten Vorrichtungen haben jedoch den Nachteil, daß das Übertragungselement (meist Zylinder mit doppelt oder einfach wirkenden Kolben) mit der pendelnden Achse einerseits und dem Rahmen andererseits fest verbunden ist, so daß die Kolben jeder Bewegung der Achse zwangsläufig folgen müssen. Durch diese Tatsache ergibt sich naturgem. ein erhöhter Verschleiß in den Durchführungen, Dichtungen und Kolbenstangen und besteht dadurch die große Gefahr, daß durch eintretende Leckölverluste die Blockierung teilweise oder ganz verlorengeht.. However, these known devices have the disadvantage that the Transmission element (usually cylinder with double or single-acting piston) with the oscillating axle on the one hand and the frame on the other hand is firmly connected, so that the pistons must necessarily follow every movement of the axis. Through this The fact arises naturally. increased wear in the bushings, seals and piston rods and there is therefore a great risk of leakage oil losses occurring the blockage is partially or completely lost.
Die nachfolgende Lösung gibt bei ausgeschalteter Blockierung die pendelnd aufgehängte Achse vollkommen frei, so daß durch die Kreisbewegung, welche die Achse beschreibt, keine Seitendrücke, die Kolben und Dichtungselemente deformieren und verschleißen, auftreten können. Außerdem gleicht diese Lösung automatisch auftretende Leckverluste aus und gewährleistet immer eine feste, kraftschlüssige Verbindung zwischen Kolben und Achse. Das ist bei den bekannten hydraulischen Einrichtungen nicht der Fall, weil schon die geringste Fehlmenge an dem Übertragungsmedium ein weites und gefährliches Nachgeben der Blockierung bewirkt. The following solution gives the pendulum suspended axis completely free, so that by the circular movement which the axis describes, no side pressures that deform the piston and sealing elements and wear out. Also, this solution resembles those that occur automatically Leakage losses and always guarantees a firm, force-fit connection between piston and axle. This is the case with the known hydraulic devices not the case, because even the slightest shortfall in the transmission medium causes wide and dangerous yielding of the blockage.
Beschreibung Zwischen dem Rahmen 15, um den Punkt 16 der pendelnd aufgehängten Achse 17 befinden sich die Zylinder 11 mit den Kolbenstangen 12 und die Federn 13, die die Kolbenstangen 12 in Ruhe-oder in Fahrstellung der Blockierung von den Auflagen 14 der Achse 17 abheben.Description Between the frame 15, around the point 16 of the pendulum suspended axis 17 are the cylinder 11 with the piston rods 12 and the springs 13 which block the piston rods 12 in the rest or driving position lift off the supports 14 of the axis 17.
Bei Betätigung der Blockierung strömt Druckluft durch die Leitung 1 einerseits in den Arbeitsraum a des Füllzylinders 2 und in den Arbeitsraum c des Schiebers 5. Dadurch werden die Leitungen 10 am Schieber 5 blockiert. Gleichzeitig verschiebt sich der Kolben 3 des Füllzylinders 2 und läuft Öl aus seinem Arbeitsraum b über die Leitung 9, die Rückschlagventile 4, die Leitung 10 in den Arbeitsraum d des Zylinders 11 und verschiebt die Kolbenstange 12 entgegen der Federkraft der Feder 13 soweit nach unten, bis die Kolbenstangen 12 die kraftschlüssige Verbindung mit der Achse 17 in jeder Lage herstellen. Versucht nun eine einseitig in der Achse 17 angreifende Kraft die Kolbenstangen 12 nach oben zu verschieben, so ist der Rückfluß des Öles durch die Leitung 10 durch die Stellung des Schiebers 5 und der Sperrichtung des Rückschlagventiles 4, verhindert. Die Achse ist also blockiert. Tritt am Kolben 11 ein Leckölverlust ein, so speist automatisch der Füllzylinder 2 über das Rückschlagventil 4 Öl in diesen Zylinder nach, so daß immer die kraftschlüssige Verbindung aufrecht erhalten wird. Zum Lösen der Blockierung wird Druckluft über die Leitung 1 aus dem Arbeitsraum a des Zylinders 2 und aus dem Arbeitsraum c des Schiebers 5 abgelassen. Die Feder 7 im Schieber 5 drückt den Schieberkolben 6 nach oben. Die Federn 13 an den Kolbenstangen 12 drücken das Öl über die Leitung 10 und die inzwischen vom Schieberkolben 6 freigegebene Leitung 8 zurück in den Füllzylinder, dessen Kolben 3 sich dadurch nach dem Arbeitsraum a verschiebt. Die Kolbenstangen 12 stehen also in Fahrstellung der Blockierung auf der Auflagepfanne 14 der Achse 17 entsprechend dem vorgesehenen Ausschlag und gewährleisten ein vollkommen freies Ausschwingen der Achse auf den vollen Pendelausschlag. Die Betätigung der Achsblockieranlage kann sowohl am Unterwagen wie auch vom Führersitz des drehbaren Oberteiles, insbesondere bei Baggern und Kranen vorgenommen werden. Die Leitung 1 kann dabei über ein entsprechendes Ventil mit der Feststellbremse des Gerätes verbunden werden, so daß beim Anziehen der Feststellbremse gleichzeitig die Blockierung in Tätigkeit tritt.When the blockage is activated, compressed air flows through the line 1 on the one hand in the working space a of the filling cylinder 2 and in the working space c of the slide 5. This blocks the lines 10 on the slide 5. Simultaneously the piston 3 of the filling cylinder 2 moves and oil runs out of its working space b via line 9, check valves 4, line 10 into the working space d of the cylinder 11 and moves the piston rod 12 against the spring force of the Spring 13 down until the piston rods 12 form the positive connection with the axis 17 in each position. Now try a one-sided in the axis 17 acting force to move the piston rods 12 upwards, so is the reflux of the oil through the line 10 by the position of the slide 5 and the blocking direction of the check valve 4, prevented. So the axis is blocked. Kick on the piston 11 a leakage oil loss, the filling cylinder 2 automatically feeds via the check valve 4 oil in this cylinder, so that the positive connection is always upright is obtained. To release the blockage, compressed air is supplied via line 1 from the Working space a of the cylinder 2 and drained from the working space c of the slide 5. The spring 7 in the slide 5 pushes the slide piston 6 upwards. The springs 13 on the piston rods 12 push the oil through the line 10 and the meanwhile from the slide piston 6 released line 8 back into the filling cylinder, the piston 3 of which is thereby after the working space a moves. The piston rods 12 are therefore in the driving position the blocking on the support pan 14 of the axis 17 according to the intended Deflection and ensure a completely free swing of the axis on the full swing of the pendulum. The axle lock system can be activated on the undercarriage as well as from the driver's seat of the rotating upper part, especially in excavators and cranes be made. The line 1 can with a corresponding valve the parking brake of the device, so that when the parking brake is applied at the same time the blocking is activated.
