Description

Es ist bekannt, in hydraulisch betätigten Anlagen, beispielsweise hydraulischen Bremsen oder auch hydraulisch betätigten Kupplungen die Druckkammer mittels Ringmanschetten abzudichten. Diese Manschetten besitzen bekanntlich Abdichtungslippen, die im wesentlichen durch die Eigenspannung des Dichtungswerkstoffes an der abzudichtenden Fläche anliegen und bei der Betätigung der Vorrichtung durch das Druckmittel zusätzlich beaufschlagt werden.It is known in hydraulically operated systems, for example hydraulic brakes or hydraulically operated clutches the pressure chamber to be sealed with ring collars. These cuffs are known to have sealing lips, which is essentially due to the internal stress of the sealing material on the one to be sealed On the surface and additionally when the device is actuated by the pressure medium be applied.

Bei Manschettendichtungen größerer Abmessung kann, insbesondere wenn weniger elastische Gummi-oder Kunstgummisorten Verwendung finden, der Fall eintreten, daß in drucklosem Zustand dieLippen nicht völlig dicht an der abzudichtenden Fläche anliegen, so daß bei Betätigung, Druckmittel verlorengeht. Es ist zur Vermeidung dieses Nachteiles bereits vorgeschlagen worden, Drahtspiralen in die Dichtungen einzulegen, die entweder auf Zug oder Druck beansprucht, die Manschettenlippen im Ruhezustand an die Abdichtungsfläche andrücken. Bei Ringmanschetten größeren Durchmessers reichen derartige Spiralen nicht aus, da diese auf die erforderliche Länge keine ausreichende Knickfestigkeit besitzen. Erfindungsgemäß wird daher an Stelle derartig bekannter Stützfedern ein Stützkörper in die Ringmanschette eingelegt, auf dem sich nach innen gerichtete elastische Ansätze der Manschettenlippe abstützen. Als Stützkörper kann erfindungsgemäß eine Drahtspirale dienen.With cuff seals of larger dimensions, especially if less elastic rubber or synthetic rubber types are used, the case occurs, that in the unpressurized state the lips are not completely close to the surface to be sealed applied so that when actuated, pressure medium is lost. It's for avoidance this disadvantage has already been proposed to wire spirals in the seals insert, which is subject to either tension or pressure, the cuff lips in the Press rest position on the sealing surface. For ring cuffs with a larger diameter such spirals are not sufficient, as they do not have the required length have sufficient resistance to buckling. According to the invention, therefore, instead of such known support springs, a support body is inserted into the annular collar, on which Support inwardly directed elastic lugs on the cuff lip. As a support body According to the invention, a wire spiral can be used.

In der Abb. i ist eine Ringmanschette gemäß Erfindung im Schnitt dargestellt, und zwar zeigt die linke Hälfte der Abb. i die Manschette im uneingespannten Zustand, auf der rechten Hälfte im eingespannten Zustand. Die Manschette i besitzt zwei Lippen 2 und 3, die wiederum nach innen gerichtete J#nsätze ,4. bzw. 5 besitzen. In den Innenraum der Manschette ist eine Drahtspirale 6 eingelegt.In Fig. I, a ring collar according to the invention is shown in section, the left half of Fig. i shows the cuff in the unclamped state, on the right half when clamped. The cuff i has two lips 2 and 3, which in turn are inwardly directed junctions, 4. or 5 own. In the A wire spiral 6 is inserted inside the cuff.

Die Manschettenlippen sind, wie bei 2 dargestellt, konisch ausgebildet, der Ansatz 4. verläuft annähernd parallel dem Manschettenboden. Wird eine derartige Manschette in einen Zylinder 7 eingebaut, so wird die Lippe 3 zusammengebogen, wobei sich der Ansatz. 5 auf die Spirale 6 aufschiebt. Die dadurch hervorgerufene Verformung des Ansatzes 5 und damit der Lippe 3 bewirkt eine zusätzliche Anpressung, so daß auch im drucklosen Zustand die Manschettenlippen stets an der Dichtfläche 7 anliegen.The cuff lips are, as shown at 2, conical, approach 4. runs approximately parallel to the bottom of the cuff. Will such a Cuff installed in a cylinder 7, so the lip 3 is bent together, wherein the approach. 5 pushes onto the spiral 6. The resulting deformation of the approach 5 and thus the lip 3 causes additional pressure, so that Even in the unpressurized state, the cuff lips always rest against the sealing surface 7.

In Abb. 2 ist eine ganze Manschette im verkleinerten Maßstab wiedergegeben.In Fig. 2 a whole cuff is shown on a reduced scale.
