"Schaftlagerdichtung, insbesondere für Kolbenschäfte von hydraulischen Soiiwingungsdämpfern". "Skirt bearing seal , especially for piston shafts of hydraulic vibration dampers".

Die Heuerung betrifft eine Sohaftlagerdichtung, insbesondere für Kolbenschäfte von hydraulischen Schwingungsdämpfern. Sie besteht aus einem Lagerdichtungskörper mit armiertem Stützring und zwei Abdichtungslippen für den Kolbenschaft, von denen die eine unter der Wirkung eines Spannringes steht.The hiring relates to a bonded bearing seal, in particular for piston shafts of hydraulic vibration dampers. It consists of a bearing seal body with a reinforced support ring and two sealing lips for the piston skirt, one of which is under the action of a clamping ring.

!Teuerungsgemäß besteht der gegen die Innenwandung des Druckzylinders wirkende Bereich der Dichtung aus einem im Querschnitt annähernd trapezförmigen, den konisch verlaufenden, an die Armierung anschließenden Teil verlängernden Ringteil, der durch das JPührungslager des Schaftes beim Einbringen der Dichtung derart verformbar ist, daß der zuerst bestehende Hohlraum zwischen dem Konusteil der Dichtung und der Innenwandung des Druckzylinders annähernd ausgefüllt ist.! According to the price, it exists against the inner wall of the pressure cylinder effective area of the seal consisting of an approximately trapezoidal cross-section, the conical, to the reinforcement adjoining part lengthening ring part, which by the J guide bearing of the shaft when inserting the Seal is deformable in such a way that the first existing cavity between the conical part of the seal and the inner wall of the printing cylinder is approximately filled.

Durch diese Ausbildung wird mittels statischer Abdichtung zwischen dem Dichtungskörper und der Innenwandung des Druckzylinders sichergestellt, daß Unrundigkeiten der Innenwandung des Zylinders ausgeglichen werden und eine leinstbearbeitung des Druckzylinders entbehrlich wird.By means of this design, a static seal between the sealing body and the inner wall of the pressure cylinder ensures that irregularities in the inner wall of the cylinder are compensated and a fine machining the printing cylinder is dispensable.

Die Schaftlagerdichtung wird in bekannter Weise durch Verkleidung, Einrollen, Verschraubung, Verklammerung od. dgl. mit dem Druckzylinder des Dämpfers verbunden.The shaft bearing seal is made in a known manner by cladding, Rolling, screwing, clamping or the like. Connected to the pressure cylinder of the damper.

Die Zeichnung zeigt eine beispielsweise Ausführungsform der Schaftlagerdichtung im Schnitt j links nach erfolgtem Einbringen und entsprechender Verformung, rechts in unverformtem Zustand. The drawing shows an example embodiment of the Shaft bearing seal in section j on the left after it has been introduced and the corresponding deformation, on the right in the undeformed state.

Die Innenwandung des Druckzylinders 2 ist mit 1 bezeichnet, die Armierung der Schaftlagerdichtung mit 3 und der hieran anschließende Teil mit 4· Dieser wird durch den konisch verlaufenden, im Querschnitt annähernd trapezförmigen Ringteil 5 verlängert. Gegen diesen drückt beim Einbringen der Schaftlagerdichtung das Führungslager β für den Kolbenschaft 7>The inner wall of the pressure cylinder 2 is denoted by 1, the reinforcement of the shaft bearing seal by 3 and the one attached to it adjoining part with 4 · This is due to the conical, Ring part 5 which is approximately trapezoidal in cross section extended. When the shaft bearing seal is introduced, the guide bearing β for the piston shaft 7> presses against this
