Die Erfindung betrifft einen hydraulischen Zylinder mit einem Zylinderrohr und zwischen zwei Endanschlägen längsverschiebbaren Kolbenstange mit Kolben und einer an beiden Endanschlägen einstellbaren wirksamen Endlagendämpfung.The invention relates to a hydraulic cylinder with a cylinder tube and a piston rod with piston that can be moved longitudinally between two end stops and an effective end position damping that can be adjusted at both end stops.
Die Aufgabe, einen hydraulischen Zylinder der eingangs genannten Gattung zur Verfügung zu stellen, der an beiden Endanschlägen eine einstellbare wirksame Endlagendämpfung mit geringem Aufwand ermöglicht, wird erfindungsgemäß dadurch gelöst, dass jeweils vor der Endlage hintereinanderliegend kleine Mediumabflussbohrungen in das Zylinderrohr eingebracht werden. Die Summe der Bohrungen ergibt den Abflussquerschnitt im ungebremsten Zustand. Die Anzahl und Größe der Bohrungen wird durch die gewünschte Dämpfungslänge bestimmt. Der abzubremsende Kolben verschließt eine Bohrung nach der anderen und verringert dadurch jeweils den Gesamtabflussquerschnitt, dadurch wird eine gezielte Dämpfung der Kolbenbewegung in Abhängigkeit der Kolbenposition vorgegeben.The task of providing a hydraulic cylinder of the type mentioned at the beginning, which enables adjustable, effective end position damping at both end stops with little effort, is achieved according to the invention by making small medium drainage holes one behind the other in the cylinder tube in front of the end position. The sum of the holes gives the drainage cross-section in the unbraked state. The number and size of the holes is determined by the desired damping length. The piston to be braked closes one hole after the other and thereby reduces the total drainage cross-section, thereby providing targeted damping of the piston movement depending on the piston position.
In der weiteren Ausgestaltung der vorliegenden Erfindung ist vorgesehen, dass ein, mit mechanischen Abdichtelementen versehenes drehbares oder verschiebbares Einstellelement vorhanden ist, das die gleichen übereinanderliegenden Mediumabflussbohrungen wie im Zylinderrohr aufweist. Durch Drehen oder Verschieben wird die Bohrungslage gegenüber dem Zylinderrohr verändert und der Abflussquerschnitt verringert sich. Dadurch wird eine von außen zu betätigende Einstellbarkeit der Dämpfung durch Drosselwirkung erreicht.In a further embodiment of the present invention, a rotatable or movable adjustment element is provided with mechanical sealing elements, which has the same medium discharge holes arranged one above the other as in the cylinder tube. By rotating or moving, the position of the holes relative to the cylinder tube is changed and the discharge cross-section is reduced. This enables the damping to be adjusted from the outside by means of a throttling effect.
Da in den Endstellungen des Kolbens am jeweiligen Anschlag die Drosselbohrungen durch den Kolben verschlossen sind, beim Anfahrvorgang des Zylinders aber der volle Anschlussquerschnitt benötigt werden kann, ist an der jeweiligen Endlage ein Rückschlagventil vorgesehen, das beim Arbeitsvorgang den benötigten Querschnitt durch den Betriebsdruck des Zylinders freigibt und beim Dämpfen diesen Zugang aber sicher verschließt und den Mediumabfluss nur über die erfindungsgemäßen Bohrungen zulässt.Since in the end positions of the piston at the respective stop the throttle bores are closed by the piston, but the full connection cross-section may be required when starting up the cylinder, a check valve is provided at the respective end position which releases the required cross-section through the operating pressure of the cylinder during the working process and securely closes this access during damping and only allows the medium to flow out via the bores according to the invention.
Diese erfindungsgemäße Endlagendämpfung kann in allen hydraulischen Zylindern angewendet werden.This end position damping according to the invention can be used in all hydraulic cylinders.
