Hintergrund der Erfindungbackground the invention
Derartig gattungsgemäß ausgebildete Wälzlager werden als Lenkungslager in der Kraftfahrzeugindustrie eingesetzt, wobei der Markt Lenkungslager mit einer sehr hohen Steifigkeit bei gleichzeitig niedrigem Reibmoment verlangt. Ursache für diese Forderung sind die immer höher werdenden Ansprüche der Kunden auf geringe Schwingungen und hohe Frequenz bei Hochgeschwindigkeitsfahrten. Ebenfalls müssen die immer schwerer werdenden Lenkräder ohne negativen Einfluss auf das Eigenschwingungsverhalten abgestützt werden. Ein weiterer Punkt sind die erhöhten Anforderungen an das Lenkungslager bei einem Crash.Such Generically trained roller bearing are used as steering bearings in the automotive industry, where the market steering bearings with a very high rigidity simultaneously requires low friction torque. Cause of this requirement they are always higher expectant claims the customers to low vibrations and high frequency in high-speed driving. Likewise the ever heavier steering wheels without negative impact be based on the natural vibration behavior. Another point are the heightened ones Requirements for the steering bearing in a crash.

Zusammenfassung der ErfindungSummary the invention
Ausgehend von den Nachteilen des bekannten Standes der Technik liegt der Erfindung daher die Aufgabe zugrunde, ein gattungsgemäßes spielfreies Wälzlager derart weiter zu entwickeln, dass einerseits die Steifigkeit verbessert und andererseits die Steifigkeit nicht durch das Elastomerelement allein bestimmt ist.outgoing from the disadvantages of the known prior art is the invention therefore, the object of a generic play-free bearings continue to develop so that on the one hand improves the rigidity and on the other hand, the rigidity not by the elastomeric element alone is determined.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil in Verbindung mit dessen Oberbegriff dadurch gelöst, dass einer der beiden äußeren Laufringe als ein Massivteil ausgebildet ist, der mit seiner Mantelfläche an einer Innenseite der Außenhülse und seiner Stirnseite an einem Bord der Außenhülse abgestützt ist, während der zugehörige andere äußere Laufring als ein spanlos geformtes Blechteil ausgebildet ist, der von der Außenhülse so aufgenommen ist, dass seine axiale Verschiebung innerhalb der Außenhülse begrenzt ist, wobei der äußere Laufring an seinem radial innenliegenden Teil wenigstens teilweise vom Bord der Außenhülse überdeckt ist und von der Außenhülse und deren Bord durch ein axialen und ein radialen Spalt beabstandet angeordnet ist.According to the invention this Task according to the characterizing part in conjunction with the preamble thereof solved by that one of the two outer races is formed as a solid part, with its lateral surface on a Inside of the outer sleeve and its end face is supported on a board of the outer sleeve, while the associated other outer race is designed as a non-cutting shaped sheet metal part of the Outer sleeve so recorded is that limits its axial displacement within the outer sleeve is, the outer race at its radially inner part at least partially from the board the outer sleeve covered is and from the outer sleeve and whose board is spaced apart by an axial and a radial gap is.
Der Vorteil dieser erfindungsgemäßen Lagerausbildung liegt insbesondere darin, dass durch den massiven Außenring und durch den Wegfall eines elastischen Einlageringes die Steifigkeit in etwa verdoppelt ist, wobei die Steifigkeit im Sinne der Erfindung durch die Eingrenzung des axialen Verschiebweges des spanlos geformten äußeren Laufringes bestimmt ist. Dies hat wiederum den Vorteil, dass das Lager nur leicht vorgespannt zu werden braucht, was sich positiv auf das Reibmoment auswirkt. Mit anderen Worten, das Reibmoment ist aufgrund der geringen Vorspannung niedrig, obwohl die Steifigkeit entsprechend hoch ist. Ein weiterer Vorteil liegt darin, dass durch den Wegfall eines elastischen Einlageringes die Fertigungskosten gesenkt sind. Ein weiterer Vorteil ist durch den massiven äußeren Laufring bedingt, weil dieser das Lager stromleitend macht.The advantage of this bearing design according to the invention is, in particular, that the stiffness is approximately doubled by the massive outer ring and by eliminating an elastic insert ring, wherein the stiffness in the context of the invention by the delimitation of the axial displacement path of the chipless outer race is determined. This in turn has the advantage that the bearing only needs to be slightly biased, which has a positive effect on the friction torque. In other words, the friction torque is low due to the low bias, although the rigidity is correspondingly high. Another advantage is that the production costs are reduced by eliminating an elastic insert ring. Another advantage is due to the massive outer race because it makes the bearing conductive.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 4 beschrieben.Further advantageous embodiments of the invention are in the dependent claims 2 to 4 described.
So ist nach Anspruch 2 vorgesehen, dass der spanlos geformte einstückig ausgebildete äußere Laufring einen schräg zu einer Lagerachse sich erstreckenden, eine Außenlaufbahn tragenden Mittelteil aufweist, an den sich an einem radial außenliegenden und an einem radial innenliegenden Ende je ein axial nach außen gerichteter Flansch anschließt, so dass zwischen beiden Flanschen und dem die Laufbahn tragenden Mittelteil ein nach außen offener umlaufender Ringraum gebildet ist, in dem der elastische Einlagering aufgenommen ist, wobei der vom Bord der Außenhülse und vom radial außenliegenden Flansch gebildete axiale Spalt kleiner als der axiale Spalt ist, der vom Bord der Außenhülse und vom radial innenliegenden Flansch gebildet ist.So is provided according to claim 2, that the chipless formed integrally formed outer race a sloping to a bearing axis extending, an outer raceway carrying central part has, at at a radially outer and at a radial inside each end of an axially outwardly directed flange connects, so that between the two flanges and the race-bearing middle part an outward open circumferential annular space is formed, in which the elastic Inserted bearing ring, which is from the board of the outer sleeve and from the radially outer Flange formed axial gap is smaller than the axial gap, the from the board of the outer sleeve and is formed by the radially inner flange.
Der Vorteil dieser Ausführungsvariante liegt insbesondere darin, dass zum einen durch die konstruktive Ausbildung des Lageraußenringes der elastische Einlagering sicher aufgenommen ist, während zum anderen die Aufnahme von axialen Kräften verbessert ist, da der axial verschiebbare Außenring am radial außenliegenden Ende des Bordes der Außenhülse zuerst zur Anlage gelangt. Dies bedeutet, der Bord der Außenhülse kann aufgrund der geringen Hebelwirkung auch bei hohen auftretenden Axialkräften nicht aufgebogen werden.Of the Advantage of this embodiment lies in the fact that on the one hand by the constructive Training the bearing outer ring the elastic insert ring is securely received while to other the absorption of axial forces is improved because of axially displaceable outer ring at the radially outer End of the rim of the outer sleeve first comes to the plant. This means the board of the outer sleeve can not due to the low leverage even at high axial forces occurring be bent up.
Nach einem weiteren zusätzlichen Merkmal der Erfindung gemäß Anspruch 3 ist vorgesehen, dass der elastische Einlagering an seinem radial innenliegenden Teil einen Vorsprung aufweist, der mit Vorspannung am spanlos geformten äußeren Laufring anliegt.To another additional Feature of the invention according to claim 3 it is provided that the elastic insert ring at its radially inside part has a projection with bias on the chipless outer race is applied.
Hierbei ist von Vorteil, dass der axial verschiebbare spanlos geformte Außenring in seinem Querschnitt einfacher zu fertigen ist und dass die Vorspannung ebenfalls sehr gering sein kann, weil diese durch den Vorsprung des radial innenliegenden Teils des Einlageringes bestimmt ist.in this connection is advantageous that the axially displaceable non-cutting shaped outer ring in its cross-section is easier to manufacture and that the bias can also be very small, because these by the projection the radially inner part of the insert ring is determined.
Schließlich ist nach einem letzten Merkmal gemäß Anspruch 4 vorgesehen, dass die Außenhülse an ihrer Mantelfläche gleichmäßig voneinander beabstandete, in radialer Richtung hervorstehende Rippen aufweist. Dadurch ist sichergestellt, dass sich Differenzen in der Gehäuseaufnahmebohrung in einfacher Weise ausgleichen lassen.Finally is according to a last feature according to claim 4 provided that the outer sleeve on her lateral surface evenly spaced, Having radially protruding ribs. This is ensured that differences in the housing receiving bore in easier Let it equalize.
