Abstract
Axial-Wälzlager (1), aufweisend zwei parallel zueinander ausgerichtete Axiallagerscheiben (2, 3), zwischen denen eine Vielzahl an Wälzkörpern (4) angeordnet ist, wobei an einem der beiden Lagerscheiben (2, 3) eine Anlaufscheibe (7) angeordnet ist, die mit der Lagerscheibe (3) derart korrespondiert, dass ein Winkelversatz am Axial-Wälzlager (1) ausgleichbar ist. Axial rolling bearing (1), comprising two mutually parallel thrust washers (2, 3), between which a plurality of rolling elements (4) is arranged, wherein on one of the two bearing discs (2, 3) a thrust washer (7) is arranged, with the bearing disc (3) corresponds such that an angular offset on the thrust roller bearing (1) can be compensated.
Description
Die Erfindung betrifft ein Axial-Wälzlager, insbesondere ein Axial-Nadellager, nach dem Oberbegriff des Anspruchs 1. Des Weiteren betrifft die Erfindung ein Ausrücklager für eine Schalttrennkupplung mit einem solchen Axial-Wälzlager.The invention relates to an axial rolling bearing, in particular an axial needle bearing, according to the preamble of
Allgemein sind Axial-Wälzlager in unterschiedlichen Bauweisen und Ausführungen bekannt. Beispielhafte Axial-Wälzlager, insbesondere Axial-Nadellager, sind in den Druckschriften
In der
Aufgabe der vorliegenden Erfindung ist es, ein rationell herstellbares und weiterentwickeltes Axial-Wälzlager aufzuzeigen, das einen Winkelversatzausgleich ermöglicht.Object of the present invention is to show a rationally producible and developed thrust roller bearing, which allows an angular misalignment.
Zur Lösung der erfindungsgemäßen Aufgabe wird das im Anspruch 1 angegebene Axial-Wälzlager und in Anspruch 4 ein Ausrücklager mit einem solchen erfindungsgemäßen Axial-Wälzlager vorgeschlagen. Optionale vorteilhafte Ausgestaltungen der Erfindung ergeben sich ganz oder teilweise aus den abhängigen Ansprüchen.To achieve the object of the invention specified in
Das erfindungsgemäße Axial-Wälzlager, insbesondere Axial-Nadellager, Axial-Rollenlager oder Axial-Kugellager, weist zwei parallel zueinander ausgerichtete Axiallagerscheiben auf, zwischen denen eine Vielzahl an Wälzkörpern angeordnet ist. Das erfindungsgemäße Axial-Wälzlager zeichnet sich dadurch aus, dass an einem der beiden Lagerscheiben eine Anlaufscheibe angeordnet ist, die mit der Lagerscheibe derart korrespondiert, dass ein Winkelversatz am Axial-Wälzlager ausgleichbar ist. Ferner ist vorzugsweise ein radialer Versatz am Axial-Wälzlager ausgleichbar. Das bedeutet, dass die Anlaufscheibe relativ zu den Lagerscheiben radial verschiebbar ist. The axial roller bearing according to the invention, in particular axial needle roller bearings, axial roller bearings or thrust ball bearings, has two mutually parallel thrust washers, between which a plurality of rolling elements is arranged. The axial roller bearing according to the invention is characterized in that a thrust washer is arranged on one of the two bearing discs, which corresponds to the bearing disc such that an angular offset on the axial roller bearing can be compensated. Furthermore, preferably a radial offset on the axial rolling bearing can be compensated. This means that the thrust washer is radially displaceable relative to the bearing discs.
In einer bevorzugten Ausführungsform weist die Anlaufscheibe an der der Lagerscheibe zugewandten Stirnseite eine konvexe Wölbung auf. Die der Anlaufscheibe zugewandten Stirnseite der Lagerscheibe ist vorzugsweise konisch mit einer konkaven Wölbung ausgebildet.In a preferred embodiment, the thrust washer on the end face facing the bearing disk has a convex curvature. The thrust washer facing end side of the bearing plate is preferably formed conically with a concave curvature.
Vorzugsweise weist die Anlaufscheibe Kunststoff auf. Durch die Verwendung von Kunststoff an der Anlaufscheibe wird ein ruhigerer Lauf des Axial-Wälzlagers erreicht. Beispielsweise ist die Anlaufscheibe mit Kunststoff umspritzt. Alternativ ist die Anlaufscheibe komplett oder teilweise aus Kunststoff hergestellt.Preferably, the thrust washer on plastic. By using plastic on the thrust washer, a smoother running of the axial roller bearing is achieved. For example, the thrust washer is encapsulated in plastic. Alternatively, the thrust washer is completely or partially made of plastic.
Das erfindungsgemäße Ausrücklager für eine Schalttrennkupplung eines Kraftfahrzeugs weist ein oben beschriebenes erfindungsgemäßes Axial-Wälzlager auf. Die Anlaufscheibe ist vorzugsweise schwungradseitig am Axial-Wälzlager angeordnet.The release bearing according to the invention for a shift disconnect clutch of a motor vehicle has an above-described inventive axial roller bearing. The thrust washer is preferably arranged on the flywheel side on the axial rolling bearing.
