Abstract
Description
Die Erfindung bezieht sich auf ein Tripodegelenk umfassend einen Tripodestern mit radial abstehenden Zapfen, die an ihrem Außenumfang einen rotationssymmetrischen Kugelflächenteilabschnitt aufweisen und an ihrem Stirnende dachkantförmig ausgebildet sind. Weiterhin bezieht sich die Erfindung auf ein Verfahren zur Herstellung eines Tripodesterns.The The invention relates to a tripod joint comprising a tripod ester with radially projecting pins, which on its outer circumference a rotationally symmetrical Spherical surface Part have and are formed at the front end roof edge. Farther The invention relates to a method for producing a Tripod star.
Tripodegelenke mit einem Tripodestern sind aus dem Stand der Technik allgemein bekannt. Die Zapfen dieser Gelenke sind an ihrem Außenumfang im Wesentlichen kugelförmig ausgebildet, um jeweils einen Lagerinnenring eines Rollelements abzustützen, das in einem Gelenkaußenteil axial geführt ist.tripod joints with a tripod ester are well known in the art known. The pins of these joints are on their outer circumference in the Essentially spherical designed to each have a bearing inner ring of a rolling element support, that in an outer joint part axially guided is.
Der
Tripodestern wird üblicherweise
umformtechnisch hergestellt. Dabei erhalten die freien Stirnenden
der Zapfen zur Einhaltung technisch möglicher Umformgrade eine leichte
Dachkantform. Diese Dachkantform lässt sich somit nicht vermeiden.
Sie verursacht bei der Herausarbeitung des rotationssymmetrischen
Kugelflächenteilabschnitts,
der für die
Lagerung eines Rollelements mit hoher Genauigkeit hergestellt werden
muss, zu einem unterbrochenen Schnitt. Die
Der Erfindung liegt daher die Aufgabe zugrunde, den Werkzeugsverschleiß bei der Herstellung eines Tripodesterns eines Tripodegelenks zu verringern.Of the The invention is therefore based on the object, the tool wear in the To reduce production of a Tripodesterns a tripod joint.
Diese Aufgabe wird durch ein Tripodegelenk gemäß Patentanspruch 1 gelöst. Das erfindungsgemäße Gelenk zeichnet sich dadurch aus, dass zwischen dem Kugelflächenteilabschnitt und dem nicht-rotationssymmetrischen Stirnende eine Fase vorgesehen ist, welche die Dachkantform anschneidet, jedoch im Übergang zum Kugelflächenteilabschnitt durch die Dachkantform nicht mehr unterbrochen ist. Anstelle einer Fase kann auch ein Radius vorgesehen sein.These Task is solved by a tripod joint according to claim 1. The joint according to the invention is characterized in that between the spherical surface portion and a non-rotationally symmetrical front end provided a chamfer which intersects the Dachkantform, however, in the transition to the spherical surface part section is no longer interrupted by the roof edge shape. Instead of a Chamfer can also be provided a radius.
Hierdurch wird der bisher durch die Dachkantform verursachte Werkzeugsverschleiß vermieden.hereby the tool wear previously caused by the roof edge shape is avoided.
Die vorstehend genannte Aufgabe wird ferner durch ein Verfahren zur Herstellung eines Tripodesterns für ein Tripodegelenk gemäß Patentanspruch 10 gelöst. Hierbei ist vorgesehen, zunächst einen Tripodestern-Rohling umformtechnisch herzustellen, wobei an der Stirnseite eines jeden Zapfens eine Dachkantform ausgeformt wird, sowie eine die Dachkantform anschneidende Fase oder ein die Dachkantform anschneidender Radius, welche bzw. welcher einen durch die Dachkantform ununterbrochenen rotationssymmetrischen Bereich ausbildet. Anschließend wird dann aus dem an die Fase bzw. den Radius axial anschließenden Abschnitt des Zapfens durch Hartbearbeitung ein Kugelflächenteilabschnitt am Außenumfang des Zapfens herausgearbeitet, wobei der Schnitt durch die Dachkantform nicht unterbrochen wird.The The above object is further achieved by a method for Production of a Tripodesterns for a tripod joint according to claim 10 solved. Here it is provided, first a Tripodestern blank to produce by forming technology, wherein at the Front side of each pin a Dachkantform is formed, as well as a chamfer cutting the Dachkantform or the Dachkantform Anschneidender radius, which or one through the roof edge shape Continuous rotationally symmetric area forms. Subsequently, will then from the axially adjacent to the chamfer or the radius section the pin by hard machining a spherical surface portion on the outer circumference worked out the pin, whereby the cut through the roof edge shape is not is interrupted.
