Description

Es ist erwünscht, bei hydraulischen Schwingungsdämpfern, wile sie an Fahrzeugen benutzt werden, den Venbilöffnungsdruck vom Kolbenweg abhängig zu machen und dabei gleichzeitig die Wirkung allmählich zu steigern. Das wird gemäß der Erfindung dadurch in eünfachster Weise erreicht, daß die für die Rückführung des Kolbens dienende Feder gleichzeitig benutzt wird, um entsprechend dem Niedergang des Kolbens allmählich den Federdruck auf die Ventilplatte zu verstärken. Zu diesem Zweck stützt sich die genannte Feder auf einen mit einer anderen Feder belasteten Bolzen, der durch Umkehrhebel auf die Ventilplatte drückt und die Belastung für diese Platte darstellt. Die Zeichnung zeigt ein Beispiel einer zweckmäßigen Ausführungsform dieser Erfindung.It is desirable for hydraulic shock absorbers to wile them are used on vehicles to increase the valve opening pressure depending on the piston travel and at the same time gradually increasing the effect. That will be according to the invention thereby achieved in the easiest way that the return the piston serving spring is used at the same time to correspond to the companionway gradually increasing the spring pressure on the valve plate. To this Purpose, the said spring is based on a spring loaded with another spring Bolt that presses on the valve plate through the reversing lever and the load for this plate represents. The drawing shows an example of an expedient embodiment of this invention.

Die zur Rückführung des Kolbens i dienende Feder 2 stützt sich auf eine Platt 3, die auf einem Absatz des Bolzens 4 aufruht. Der Bolzen 4 liegt in der Ventilsitzplatte 5 und steht unter dem Druck einer Feder 6. Er stützt sich mit seinem Flansch 7 auf zwei Umkehrhebel. 8, die in dem Boden des Zylinders mittels der Wälzgelenke 9 gelagert sind. Die anderen Enden der Hebel drücken auf die Bodenventilplatte io. Bei der Abwärtsbewegung des Kolbens i wind zunächst die Feder 2 allmählich zusammengedrückt, und dieser Druck wirkt in steigendem Maße auf den Bolzen 4 und damit über die Umkehrhebel 9 auf die Bodenventilplatte io ein. Dadurch wird eine dem Kolbenweg und damit der Bewegung des Hebels des Stoßdämpfers angepaßte Dämpfungsänderung erzielt.The spring 2 used to return the piston i is supported on a plate 3 which rests on a shoulder of the bolt 4. The bolt 4 lies in the valve seat plate 5 and is under the pressure of a spring 6. It is supported with its flange 7 on two reversing levers. 8, which are mounted in the bottom of the cylinder by means of the roller joints 9. The other ends of the levers press on the bottom valve plate io. During the downward movement of the piston i, the spring 2 is initially gradually compressed, and this pressure acts to an increasing extent on the bolt 4 and thus, via the reversing lever 9, on the base valve plate io. As a result, a change in damping adapted to the piston travel and thus the movement of the lever of the shock absorber is achieved.
