Description
Kugelgelenk Die Erfindung bezieht sich auf ein Kugelgelenk, welches aus einem Gelenkgehäuse mit Lenkhebel und einem auf der Gehäuseverschlußseite abgeflachten in das Gelenkgehäuse eingesetzten Kugelkopf besteht, der an einem Zapfen angeordnet und über elastischen Werkstoff, z. B. Gummi, im Gelenkgehäuse ohne einen durch den Werkstoff auf den Kugelkopf ausgeübten oder zumindest ohne einen wesentlichen solchen Druck gelagert ist.Ball joint The invention relates to a ball joint which from a joint housing with steering lever and one flattened on the housing locking side The ball head used in the joint housing is arranged on a pin and about elastic material, e.g. B. rubber, in the joint housing without one through the Material exerted on the ball head or at least without any substantial such Pressure is stored.
Der Erfindung liegt die Aufgabe zugrunde, ein Kugelgelenk zu schaffen, bei dem der Kugelzapfen im wesentlichen nur eine Winkelbewegung in der Ebene ausführen kann, in der der Lenkhebel des Gehäuses und der Kugelzapfen liegen. Bei dieser Bewegungsbeschränkung sollen Reibungsverluste, wie sie z. B. bei einer Führung des Kugelzapfens in einem Schlitz des Gehäuses auftreten, vermieden werden.The invention is based on the object of creating a ball joint, in which the ball stud essentially only performs an angular movement in the plane can, in which the steering lever of the housing and the ball stud are located. With this restriction of movement should frictional losses, as z. B. when guiding the ball stud in one Slit of the housing occur should be avoided.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß an der Abflachungsfläche des Kugelkopfes die schneidenartige Kante eines Wulstes anliegt, der quer zu der Achse des an dem Gelenkgehäuse befindlichen Lenkhebels verläuft und ebenfalls aus elastischem Werkstoff besteht.This object is achieved according to the invention in that on the flattened surface of the ball head the blade-like edge of a bead rests, which is transverse to the Axis of the steering lever located on the joint housing runs and also from elastic material.
Bekannt sind zwar Gelenke mit in einem gehäuseartigen Gelenkteil elastisch gehaltenem Gelenkkopf an einem Zapfen, bei welchen der die Form eines Flachtellers aufweisende Gelenkkopf in seinem unteren Teil in einem ihn dicht umschließenden elastischen Werkstoff gelagert ist, während die obere Fläche des Gelenkkopfes nur in der Mitte an einem Vorsprung aus elastischem Werkstoff anliegt. Der Gelenkzapfen ist demnach allseitig winkelbeweglich und kann die Winkelausschläge nur unter Verzerrung bzw. Verwalkung des unteren elastischen Werkstoffes ausführen. Mit solchen Gelenken ist die der Erfindung zugrunde liegende Aufgabe nicht gelöst. Demgegenüber ist gemäß der Erfindung ein elastisches Kugelgelenk mit größter Leichtgängigkeit, jedoch hinreichender Stoßsicherheit geschaffen, bei welchem der Gelenkzapfen nur zu Winkelausschlägen in Achsrichtung des Lenkhebels am Gehäuse befähigt ist, das Gelenk also nicht quer zur Achse des Gelenkzapfens kippen kann, ohne daß hierdurch die gewünschte Winkelbeweglichkeit gehemmt ist; denn auf dem schneidenartigen Wulst wälzt sich die Abflachungsfläche des Kugelkopfes bei Winkelausschlägen des Gelenkzapfens ab.Although joints are known with elastic in a housing-like joint part held joint head on a pin, in which the shape of a flat plate having joint head in its lower part in a tightly enclosing it elastic material is mounted, while the upper surface of the joint head only rests in the middle on a projection made of elastic material. The pivot pin is therefore angularly movable in all directions and can only deflect the angle with distortion Execute or manage the lower elastic material. With such joints the object on which the invention is based is not achieved. In contrast, according to the invention an elastic ball joint with the greatest ease of movement, but sufficient Shock resistance created, in which the pivot pin only to angular deflections is enabled in the axial direction of the steering lever on the housing, so the joint is not transverse can tilt to the axis of the pivot pin without the desired angular mobility is inhibited; because the flattened surface rolls on the blade-like bead of the ball head at angular deflections of the pivot pin.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung.The drawing illustrates an embodiment of the invention.
Abb. 1 läßt ein Kugelgelenk in Längsansicht teilweise geschnitten erkennen; Abb. 2 ist ein Schnitt durch das Gelenk senkrecht zur Achse des Lenkhebels am Gehäuse; Abb. 3 gibt einen Schnitt nach der Linie I-I in Abb. 1 wieder: Das Kugelgelenk besteht aus dem Gelenkgehäuse 1 mit dem Lenkhebel 2 und dem Kugelzapfen 3 mit dem Kugelkopf 4, dessen oberer Teil abgeflacht ist. In das Gehäuse ist ein Gummifutter eingesetzt, welches bei dem Ausführungsbeispiel aus einem oberen Teil 5 und einem unteren Teil 6 besteht. Der obere Teil weist einen Wulst 7 quer zur Achse des Lenkhebels 2 des Gehäuses auf. Dieser Wulst liegt auf dem abgeflachten Teil des Kugelkopfes auf. Die sich an den kugeligen Teil des Kugelkopfes anlegende Innenfläche 8 des Gummifutters ist in ihrer Form und Größe dem Kugelkopf angepaßt, so daß der Kugelkopf ohne wesentliche Pressung im Futter ruht.Fig. 1 shows a ball joint partially cut in a longitudinal view; Figure 2 is a section through the hinge perpendicular to the axis of the steering arm on the housing; Fig. 3 shows a section along the line II in Fig. 1: The ball joint consists of the joint housing 1 with the steering lever 2 and the ball pin 3 with the ball head 4, the upper part of which is flattened. A rubber lining is inserted into the housing, which in the exemplary embodiment consists of an upper part 5 and a lower part 6. The upper part has a bead 7 transverse to the axis of the steering lever 2 of the housing. This bead rests on the flattened part of the ball head. The inner surface 8 of the rubber chuck, which rests against the spherical part of the ball head, is adapted in shape and size to the ball head, so that the ball head rests in the chuck without any significant pressure.
Auf der verschlossenen Gehäuseseite weist der elastische Werkstoff zu beiden Seiten des Wulstes 7 einen nach dem Umfang des Kugelkopfes hin wachsenden Abstand von der Abflachungsfläche des Kugelkopfes in Ausgangsstellung auf, so daß sich die Fläche bei Winkelausschlägen des Kugelzapfens ungehemmt auf dem schneidenartigen Wulst 7 abwälzen kann.The elastic material has on the closed side of the housing on both sides of the bead 7 a growing towards the circumference of the ball head Distance from the flat surface of the ball head in the starting position, so that With angular deflections of the ball stud, the surface is uninhibited on the blade-like Bead 7 can roll off.
Bei dem Ausführungsbeispiel ist in die Trennfuge zwischen dem Oberteil 5 und dem Unterteil 6 des Gummifutters ein Druckring 9, beispielsweise aus Stahlbronze, mit einem gewissen Abstand von dem Kugelkopf 4 eingesetzt. Der Druckring 9 dient bei größerer Belastung des Kugelgelenkes in Richtung des Lenkhebels 2 der Entlastung des Gummifutters. Der Austritt 10 des Kugelkopfzapfens 3 aus dem Gummifutter und aus dem Gehäuse ist in Richtung der Achse des Lenkhebels 2 langlochartig ausgebildet. Der Dichtungsbalg 11, welcher sich an den Kugelzapfen 3 anlegt und an letzterem durch den federnden Klemmring 12 gegen Hochrutschen gesichert ist, besteht mit dem Gummifutter aus einem Stück. Naturgemäß kann das Gelenk auch mit einer- Dichtung anderer Art, so z. B. mit einer üblichen offenen Gummikappe, versehen sein.In the embodiment is in the parting line between the upper part 5 and the lower part 6 of the rubber lining a pressure ring 9, for example made of steel bronze, used at a certain distance from the ball head 4. The pressure ring 9 is used with greater load on the ball joint in the direction of the steering lever 2 of the relief of the rubber lining. The outlet 10 of the ball head pin 3 from the rubber lining and from the housing is formed in the direction of the axis of the steering lever 2 like a slot. The sealing bellows 11, which is attached to the ball stud 3 creates and on the latter is secured against sliding up by the resilient clamping ring 12, consists of one piece with the rubber lining. Of course, the joint can also with a seal of another kind, so z. B. provided with a conventional open rubber cap be.
Die Innenfläche des Gummifutters ist mit einem geeigneten Gleitmittel versehen, so z. B. graphitiert.The inner surface of the rubber lining is coated with a suitable lubricant provided, so z. B. graphitized.
