Description

Die Erfindung betrifft einen Spannring für die Festlegung von Dichtungsbälgen, insbesondere in den Balgnuten von Kugelgelenken.The invention relates to a clamping ring for fixing sealing bellows, in particular in the Bellows grooves of ball joints.

Zur Abdichtung der Austrittsöffnung für den Kugelzapfen aus seinem Gehäuse werden gewöhnlich elastische- Abdichtbälge verwendet. Um der Ausschlagbewegung des Kugelzapfens folgen zu können, ohne daß sich die eine oder die andere Balgöffnung von der abzudichtenden Ringfläche abhebt, werden die Balgöffnungen durch einen Spannring radial festgehalten. Als Spannringe haben sich geschlossene Plastikringe oder offene Sprengringe aus Stahldraht bewährt. In bestimmten Fällen sind Plastikringe nicht einsatzfähig. Liegt dann die festzuhaltende Balgöffnung überdies noch in einer Nut, so ist die Montage eines Spannringes aus Stahl am Balg schwierig und birgt die Gefahr in sich, den Ring beim Heben über die die Nut begrenzende Wulst über seine Streckgrenze hinaus zu dehnen.For sealing the outlet opening for the ball stud elastic bellows are usually used from its housing. To the rash movement of the ball pin to be able to follow without one or the other bellows opening of the the ring surface to be sealed lifts off, the bellows openings are held in place radially by a clamping ring. as Closed plastic rings or open snap rings made of steel wire have proven their worth. In particular In some cases, plastic rings cannot be used. If the bellows opening to be held is also still in a groove, the assembly of a clamping ring made of steel on the bellows is difficult and harbors the risk of the To stretch the ring when lifting over the bead delimiting the groove beyond its yield point.

Es sind bereits Schraubenfedern für eine Teleskopfederung von Kraftfahrzeugen vorgeschlagen worden (DT-PS 8 14 255), die aus mehreren miteinander verdrillten Einzeldrähten bestehen. Diese Federbauart soll die Eigendämpfung durch Reibung der Einzeldrähte aneinander erhöhen.There have already been proposed coil springs for a telescopic suspension of motor vehicles (DT-PS 8 14 255), which consist of several individual wires twisted together. This type of spring is intended to increase the self-damping through friction between the individual wires.

Darüber hinaus ist auch schon eine auf Biegung beanspruchte Förderwagenachse vorgeschlagen worden (DT-PS 8 47 161), die aus einem Stück Drahtseil bestand. Auch für diese Anwendung waren Dämpfungsprobleme die Ursache.In addition, a truck axle that is subject to bending stress has also been proposed (DT-PS 8 47 161), which consisted of a piece of wire rope. There were also damping problems for this application the cause.

Die Aufgabe der Erfindung besteht darin, einen offenen Federring aus Stahldraht zu schaffen, der sich ohne bleibende Verformung weiter öffnen läßt, als die bisher verwendeten Spannringe.The object of the invention is to create an open spring ring made of steel wire, which Can be opened wider without permanent deformation than the previously used clamping rings.

ίο Dies wird erfindungsgemäß dadurch erreicht, daß der Federring aus mindestens zwei miteinander verdrillten Einzeldrähten hergestellt ist.ίο This is achieved according to the invention in that the Spring washer is made from at least two individual wires twisted together.

In der Zeichnung ist eine erfindungsgemäße Ausführungsform dargestellt,
is Es zeigtIn the drawing, an embodiment according to the invention is shown,
is it shows

F i g. 1 ein Kugelgelenk niit einem Abdichtungsbalg in üblicher Form, der oben und unten durch erfindungsgemäße Spannringe fixiert ist,F i g. 1 a ball joint with a sealing bellows in usual shape, which is fixed at the top and bottom by clamping rings according to the invention,

Fig.2 als Einzelheit aus Fig. 1 einen Spannring in der Nut des Balges undFig. 2 as a detail from Fig. 1, a clamping ring in the groove of the bellows and

F i g. 3 einen einzelnen Spannring schaubildlich.F i g. 3 shows a diagram of a single tension ring.

In Fig. 1 ist ein Kugelgelenkgehäuse mit 1 bezeichnet. In einer durch einen Verschlußring 2 im Gehäuse fixierten Kugelschale 3 ist ein Kugelzapfen 4 gelagert. Dieser besitzt eine Nut 5 zur axialen Fixierung eines Dichtungsbalges 6. In dieser Nut 5 liegt, ebenso wie in einer Gehäusenut 7, jeweils der untere und der obere Rand des Balges 6 und wird dort durch einen großen Spannring 8 und einen kleinen Spannring 9 axial festgelegt.In Fig. 1, a ball joint housing is denoted by 1. A ball pin 4 is mounted in a ball socket 3 fixed in the housing by a locking ring 2. This has a groove 5 for the axial fixation of a sealing bellows 6. This groove 5 is located, as in FIG a housing groove 7, each of the lower and the upper edge of the bellows 6 and is there by a large Tension ring 8 and a small tension ring 9 are axially fixed.

Nunmehr ist es durch die Verwendung des erfindungsgemäßen Spannringes möglich, zum Beispiel den Spannring 8 ohne bleibende Verformung so weit zu dehnen, daß er sich über den Durchmesser 10 hinweg in seine Nut einlegen läßt.Now it is possible through the use of the clamping ring according to the invention, for example the To stretch the clamping ring 8 without permanent deformation so far that it extends over the diameter 10 in can insert its groove.
