Abstract

The shock absorber has separate systems for controlling the compression and release strokes of the piston (2). The compression stroke forces oil from working chamber A, opening a one-way valve (5) and feeding it back through a channel (3) to a second working chamber (B) above the piston. Excess oil in this chamber flows through an overflow (7) into an integral compensating chamber (6). When the piston is withdrawn, oil from chamber B flows through the overflow into the compensating chamber and out through a channel (4) at its base, opening a second valve (8) and flowing back into working chamber A.

Description

Um bei Teleskopstoßdämpfern die Druck- und Zugstufe separat verstellbar zu machen, ist es bisher notwendig, ein externes Ausgleichsgefäß zur Aufnahme des von der Kolbenstange verdrängten Öls zu verwenden.In order to make the compression and rebound stages separately adjustable for telescopic shock absorbers, it was previously necessary to use an external expansion tank to hold the oil displaced by the piston rod.

Des weiteren sind die Verstelleinrichtungen unkomfortabel angebracht.Furthermore, the adjustment devices are uncomfortably attached.

Mit der Erfindung erzielte Vorteile liegen darin, dass diese einen Stoßdämpfer darstellt, der in der Druckstufe sowie in der Zugstufe bzw. Progression separat einstellbar ist und kein separates Ausgleichsgefäß benötigt.Advantages achieved with the invention are that it represents a shock absorber in the compression stage as well as in the rebound or progression can be set separately and no separate expansion tank is required.

Des weiteren wird eine komfortable Zugänglichkeit der Verstelleinrichtungen erreicht.Comfortable accessibility of the adjustment devices is also achieved.

Ein Schema dieser Erfindung ist in der Zeichnung Fig. 1 dargestellt und wird im folgenden näher beschrieben.A diagram of this invention is shown in the drawing Fig. 1 and will be described in more detail below.

Beim Einfahren der Kolbenstange 1 wird das Öl in der Arbeitskammer A durch die Abwärtsbewegung des Kolbens 2 in beide Kanäle 3 und 4 gedrückt, wobei der anliegende Druck das verstellbare Einwegventil 5 öffnet. Das Öl strömt somit durch das Ventil 5 in die Arbeitskammer B.When the piston rod 1 is retracted, the oil in the working chamber A is pressed into both channels 3 and 4 by the downward movement of the piston 2 , the applied pressure opening the adjustable one-way valve 5 . The oil thus flows through the valve 5 into the working chamber B.

Das sich beim Hineindrücken vergrößernde Kolbenstangenvolumen bewirkt, dass sich überschüssiges Öl aus der Arbeitskammer B durch den Überlauf 7 in die Ausgleichkammer 6 gelangt.The piston rod volume, which increases when pressed in, causes excess oil to get from the working chamber B through the overflow 7 into the compensation chamber 6 .

Beim Ausfahren der Kolbenstange 1 drückt der Kolben 2 das in der Arbeitskammer B enthaltene Öl durch den Überlauf 7 in die Ausgleichkammer 6.When the piston rod 1 extends, the piston 2 presses the oil contained in the working chamber B through the overflow 7 into the compensation chamber 6 .

Der so entstehende Druck in der Ausgleichkammer 6 sowie der entstehende Unterdruck in der Arbeitskammer A bewirkt, dass das verstellbare Einwegventil 8 öffnet und das Öl durch den Kanal 4 in die Arbeitskammer A strömt.The resulting pressure in the compensation chamber 6 and the resulting negative pressure in the working chamber A have the effect that the adjustable one-way valve 8 opens and the oil flows through the channel 4 into the working chamber A.

Das vollständige Füllen der Arbeitskammer A wird durch ein in der Ausgleichkammer eingebrachter Gasdruck garantiert.The complete filling of the working chamber A is carried out by a gas pressure introduced in the compensation chamber guaranteed.

Das verstellbare Einwegventil 5 regelt die Druckstufe und kann sowohl druckbeauflagt wie auch querschnittregulierend konstruiert sein.The adjustable one-way valve 5 regulates the pressure level and can be designed to be pressurized as well as to regulate the cross section.

Das verstellbare Einwegventil 8 regelt die Zugstufe und kann sowohl druckbeauflagt wie auch querschnittregulierend konstruiert sein.The adjustable one-way valve 8 regulates the rebound and can be designed to apply pressure as well as to regulate the cross-section.

Die mit der Erfindung erzielten Vorteile sind, dass mehrfach verstellbare Teleskopstoßdämpfer einerseits kein externes Ausgleichsgefäß benötigen sowie dass die Verstelleinrichtungen leicht zugänglich und komfortabel angeordnet werden können.The advantages achieved by the invention are that multiply adjustable telescopic shock absorbers, on the one hand, do not need external expansion tank and that the adjustment devices are easily accessible and convenient can be arranged.
