Abstract

The hinge has a link pin (10) in a housing (14). A sealing bellow (16), supported by a medium (18), is mounted at the hinge and engages at the housing. The medium supports an inner wall of the sealing bellow and a neck area engages the link pin. The medium for support consists of a foam material. The medium supports a liquid, which is placed in the inner space of the sealing bellow.

Description

Die Erfindung betrifft ein Gelenk mit einem Gelenkzapfen, der in einem Gehäuse gelagert ist, und mit einem Dichtungsbalg, der mit einem Gelenk an dem Gehäuse angreift (z. B. befestigt ist).The The invention relates to a joint with a pivot pin, which in one casing is stored, and with a sealing bellows, with a joint the housing attacks (eg is attached).

Wird das Gelenk betätigt, kann sich der Dichtungsbalg verdrehen, hierbei können sich Falten bilden, und der Balg kann einfallen.Becomes the joint is actuated, Can the bellows twist, this can form wrinkles, and the bellows can come up.

Es ist Aufgabe der vorliegenden Erfindung, das Einfallen von Dichtungsbälgen zu verhindern.It Object of the present invention, the collapse of sealing bellows prevent.

Die Aufgabe wird dadurch gelöst, dass in dem Gelenk Mittel zum Abstützen des Dichtungsbalgs vorgesehen sind.The Task is solved by in that means for supporting the sealing bellows are provided in the joint are.

Dadurch, dass der Dichtungsbalg abgestützt wird, wird das Einfallen des Dichtungsbalgs bei einem Verdrehen verhindert. Durch die Wahl der Abstützung besteht auch die Möglichkeit, die Stützkraft zu steuern und das Einfallen bis zu einem gewünschten Maße zu begrenzen. Hierbei wird die Lebensdauer des Dichtungsbalges in Bezug auf Materialermüdung erheblich erhöht. Dem entgegen wird das Einfallverhalten von bisher bekannten und üblichen Dichtungsbälgen allein durch die Balggeometrie und die Wandstärke bestimmt.Thereby, that the sealing bellows is supported, the collapse of the sealing bellows is prevented during rotation. By choosing the support there is also the possibility the support force too control and limit the collapse to a desired extent. This is the life of the bellows in terms of material fatigue considerably elevated. The opposite is the incidence of previously known and usual Dichtungsbälgen alone determined by the bellows geometry and the wall thickness.

Bevorzugt sind die Mittel zum Abstützen innerhalb des gesamten Dichtungsbalgs angeordnet, d. h sie greifen an einer Innenwand des Dichtungsbalgs an (sind dort befestigt) und sie greifen an einem Halsbereich des Gelenkzapfens an (sind dort befestigt), so dass die Balgwand von innen gestützt wird. Durch eine geeignete Wahl der Mittel wird die Stützkraft gegen die Innenwand des Balges steuerbar.Prefers are the means of support disposed within the entire sealing bellows, d. h they grab on an inner wall of the sealing bellows (are attached there) and they attack a neck area of the pivot (they are there attached), so that the bellows wall is supported from the inside. By a suitable Choice of funds becomes the support force controllable against the inner wall of the bellows.

Beispielsweise können die Mittel zum Abstützen aus Schaumstoff, vorteilhafterweise aus einem offenporigen PU-Schaumstoff bestehen.For example can the means of support made of foam, advantageously consist of an open-cell PU foam.

Alternativ kann in einem von dem Dichtungsbalg gebildeten Innenraum als Mittel zum Abstützen eine Flüssigkeit vorgesehen sein, die mit einer Druckregelung verbunden sein kann um die Stützkraft nach Belieben variieren zu können.alternative can in an interior formed by the sealing bellows as a means for supporting one liquid be provided, which may be connected to a pressure control about the support force to be able to vary at will.

Nachfolgend wird eine bevorzugte Ausführungsform der Erfindung unter Bezug auf die Zeichnung beschrieben, wobei die einzige Figur einen Schnitt durch ein erfindungsgemäßes Gelenk zeigt.following becomes a preferred embodiment of the invention described with reference to the drawing, wherein the single figure shows a section through an inventive joint shows.

Ein Gelenkzapfen 10 ist in einer Lagerschale 12 eines Gehäuses 14 gelagert.A pivot pin 10 is in a bearing cup 12 a housing 14 stored.

Ein Dichtungsbalg 16 ist an einem Halsbereich des Gelenkzapfens 10 befestigt und gleichzeitig an dem Gehäuse 14. Während üblicherweise in dem Innenraum, der von dem Dichtungsbalg 16 gebildet ist, Luft befindlich ist, ist erfindungsgemäß vorgesehen, dass ein Schaumstoffkörper 18 an der Innenwand des Dichtungsbalgs 16 einerseits abgestützt ist und andererseits am Halsbereich des Gelenkzapfens 10.A sealing bellows 16 is at a neck area of the pivot pin 10 attached and at the same time to the housing 14 , While usually in the interior of the bellows 16 is formed, air is located, the invention provides that a foam body 18 on the inner wall of the sealing bellows 16 supported on the one hand and on the other hand on the neck area of the pivot pin 10 ,

Der Schaumstoffkörper 18 verhindert, dass es zur Faltenbildung bei einer Drehung kommt.The foam body 18 Prevents wrinkling on rotation.
