Description
Die Erfindung bezieht sich auf ein Kugelgelenk für ein Kraftfahrzeugfahrwerk, mit einem Gelenkzapfen, einer geteilten Gelenkkugel mit einem oberen Kugelsegment und einem unteren Kugelsegment.The invention relates to a ball joint for a motor vehicle chassis, with a pivot pin, a split ball joint with an upper ball segment and a lower ball segment.
Ein derartiges Kugelgelenk wird im Allgemeinen als Traggelenk in dem Kraftfahrzeugfahrwerk verwendet, wobei typischerweise der Gelenkzapfen mit einem Radträger des Kraftfahrzeugfahrwerks und die Gelenkpfanne mit einem Querträger des Kraftfahrzeugfahrwerks verbunden sind, sodass das Kugelgelenk eine axiale Last aufnehmen muss. Ferner kommt es, insbesondere bei einer Lenkbewegung, zu einer Verdrehung und zu einer Verkippung des Gelenkzapfens bezüglich der Gelenkpfanne.Such a ball joint is generally used as a ball joint in the motor vehicle chassis, typically the pivot pin is connected to a wheel carrier of the vehicle chassis and the socket with a cross member of the vehicle chassis, so that the ball joint must absorb an axial load. Furthermore, in particular during a steering movement, there is a twisting and a tilting of the pivot pin with respect to the joint socket.
Aus der
Die
Bei einer Verdrehung des Gelenkzapfens bezüglich der Gelenkpfanne wird das untere Kugelsegment bezüglich des oberen Kugelsegments verdreht, wobei durch die Wälzlagerung nur geringe Reibung auftritt. Auf der Außenseite der Gelenkkugel liegt lediglich ein axial entlasteter Kontaktbereich des unteren Kugelsegments an einem korrespondierenden Kontaktbereich der Gelenkpfanne an, sodass die hier erzeugte Reibung gering ist.Upon rotation of the pivot pin relative to the socket, the lower ball segment is rotated with respect to the upper ball segment, which occurs by the rolling bearing only low friction. On the outside of the joint ball, only an axially relieved contact area of the lower ball segment rests against a corresponding contact area of the joint socket, so that the friction generated here is low.
Aufgabe der Erfindung ist es vor diesem Hintergrund,
ein kostengünstiges und auf einfache Weise montierbares Kugelgelenk zu schaffen, das eine reibungsarme Verdrehung des Gelenkzapfens bezüglich der Gelenkpfanne ermöglicht.The object of the invention is against this background,
to provide a cost-effective and easy to assemble ball joint, which allows a low-friction rotation of the pivot pin with respect to the joint socket.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Kugelgelenk mit den Merkmalen des Anspruchs 1.This object is achieved by a ball joint with the features of claim 1.
Das erfindungsgemäße Kugelgelenk weist einen Gelenkzapfen und eine geteilte Gelenkkugel auf. Die Gelenkkugel ist hierbei in ein oberes Kugelsegment und ein unteres Kugelsegment geteilt, wobei das untere Kugelsegment integral an den Gelenkzapfen angeformt ist und das obere Kugelsegment auf dem Gelenkzapfen drehbar gelagert ist. Vorzugsweise sind das obere Kugelsegment und das untere Kugelsegment jeweils im Wesentlichen halbkugelförmig ausgebildet.The ball joint according to the invention has a pivot pin and a split ball joint. The ball joint is here divided into an upper ball segment and a lower ball segment, wherein the lower ball segment is integrally formed on the pivot pin and the upper ball segment is rotatably mounted on the pivot pin. Preferably, the upper ball segment and the lower ball segment are each formed substantially hemispherical.
Das Kugelgelenk weist ferner eine Gelenkpfanne auf, die die Gelenkkugel zumindest teilweise axial und radial umschließt, sodass der Gelenkzapfen über die Gelenkkugel unverlierbar in der Gelenkpfanne gelagert ist.The ball joint further has a socket, which surrounds the ball at least partially axially and radially, so that the pivot pin is mounted captive on the ball in the joint socket.
In dem oberen Kugelsegment und in dem unteren Kugelsegment sind korrespondierende Wälzlagerrillen vorgesehen, in denen die Wälzkörper angeordnet sind. Die Wälzkörper sind somit über die korrespondierenden Wälzlagerrillen axial und radial direkt durch die beiden Kugelsegmente gestützt. Durch die Wälzlagerung der beiden Kugelsegmente zueinander wird bei einer Verdrehung des Gelenkzapfens bezüglich der Gelenkpfanne nur eine geringe Reibung erzeugt. Dadurch, dass die Kugelsegmente korrespondierende Wälzlagerrillen aufweisen, in denen die Wälzkörper angeordnet sind, kann das erfindungsgemäße Kugelgelenk kostengünstig realisiert werden, da separate Lagerschalen entfallen.In the upper ball segment and in the lower ball segment corresponding rolling bearing grooves are provided, in which the rolling elements are arranged. The rolling elements are thus supported on the corresponding rolling bearing grooves axially and radially directly by the two spherical segments. By the rolling bearing of the two spherical segments to each other only a small friction is generated with a rotation of the pivot pin with respect to the socket. The fact that the ball segments have corresponding roller bearing grooves, in which the rolling elements are arranged, the ball joint according to the invention can be realized inexpensively, since separate bearing shells omitted.
Erfindungsgemäß ist oberhalb des oberen Kugelsegments eine Gelenkkappe an dem Gelenkzapfen befestigt, die das obere Kugelsegment axial stützt. Dies ermöglicht eine einfache und zuverlässige unverlierbare Verbindung zwischen dem Gelenkzapfen und der Gelenkpfanne.According to the invention, a joint cap is attached to the pivot above the upper segment of the ball, which axially supports the upper segment of the ball. This allows a simple and reliable captive connection between the pivot pin and the socket.
Vorzugsweise ist zwischen der Gelenkkugel und der Gelenkpfanne ein Gleitkörper angeordnet, der die Gelenkkugel zumindest teilweise radial und axial umschließt und an dieser anliegt. Der Gelenkkörper besteht aus einem Material, das bezüglich der Gelenkkugel einen geringeren Reibungskoeffizienten aufweist, als das Gelenkpfannenmaterial. Hierdurch kann die im Kugelgelenk erzeugte Reibung minimiert werden, insbesondere auch bei einer Verkippung des Gelenkzapfens in der Gelenkpfanne.Preferably, a sliding body is arranged between the joint ball and the socket, which surrounds the ball joint at least partially radially and axially and bears against this. The joint body is made of a material which has a lower coefficient of friction with respect to the joint ball than the joint socket material. As a result, the friction generated in the ball joint can be minimized, in particular even with a tilting of the pivot pin in the socket.
Gemäß einer bevorzugten Ausgestaltung besteht der Gleitkörper aus Kunststoff. Kunststoffe weisen im Allgemeinen eine ausreichende Stabilität und geringe Reibungskoeffizienten auf.According to a preferred embodiment, the slider is made of plastic. Plastics generally have sufficient stability and low coefficients of friction.
Vorzugsweise sind die Wälzkörper als Wälzkugeln ausgebildet, wodurch eine besonders einfache und reibungsarme axiale und radiale Wälzlagerung der beiden Kugelsegmente ermöglicht wird.Preferably, the rolling elements are designed as rolling balls, whereby a particularly simple and low-friction axial and radial roller bearing of the two spherical segments is made possible.
Gemäß einer bevorzugten Ausgestaltung ist der Gelenkzapfen als Hohlzapfen ausgebildet. Dies ermöglicht ein leichtes Kugelgelenk, das einfach und zuverlässig an dem Fahrzeugfahrwerk befestigt werden kann.According to a preferred embodiment, the pivot pin is formed as a hollow pin. This allows a lightweight ball joint that can be easily and reliably attached to the vehicle chassis.
Im Folgenden wird ein Ausführungsbeispiel der Erfindung sowie ein nicht in den Schutzbereich des Anspruchs 1 fallendes Ausführungsbeispiel anhand der beiliegenden Figuren näher erläutert.In the following, an embodiment of the invention and a not falling within the scope of claim 1 embodiment will be explained in more detail with reference to the accompanying figures.
