Die Baubreite derartiger Stützlager wird im Wesentlichen von dem Durchmesser der Lagerkugeln bestimmt, welche bei einem durch den Getriebe- oder Kupplungshersteller festgelegten Bauraum eine nur begrenzte Bauraumnutzung hinsichtlich der Tragfähigkeit und des Schmiermittelreservoirs zulassen. Werden als Wälzköper Lagerkugeln verwendet, so lässt sich bislang aufgrund der Montagebedingungen im Kupplungsbereich nur ein Druckwinkel von maximal 25° erreichen. Da die Kupplungslasten im Wesentlichen als Axialkomponenten auftreten, sind die übertragbaren maximalen Lasten bei der geforderten Lebensdauer entsprechend begrenzt.The Width of such support bearings is essentially determined by the diameter of the bearing balls, which at a specified by the gear or clutch manufacturer Space only a limited space utilization in terms of carrying capacity and the lubricant reservoir allow. Are used as Wälzköper bearing balls used, so lets so far due to the mounting conditions in the coupling area only reach a pressure angle of 25 ° max. Because the coupling loads occur essentially as axial components, are the transferable maximum loads corresponding to the required service life.

Insbesondere ist es Aufgabe der Erfindung, ein Stützlager zu schaffen, welches bei möglichst kurzer Baubreite eine hohe Gebrauchsdauer ermöglicht und hohe Traglasten aufnehmen kann.Of the Invention is the object of the invention to provide a support bearing, which does not have described disadvantages. In particular, it is the task the invention, a support bearing to create which, if possible short width allows a long service life and high payloads can record.
Zusammenfassung der ErfindungSummary of the invention
Der Erfindung liegt die Erkenntnis zugrunde, dass sich die gestellte Aufgabe auf überraschend einfache Art und Weise dadurch lösen lässt, dass als Wälzkörper Kugelrollen verwendet werden.Of the Invention is based on the finding that the asked Task on surprisingly simple Solve it by way of fashion leaves, that as rolling elements spherical rollers be used.
Die Erfindung geht gemäß den Merkmalen des Hauptanspruchs daher von einem Stützlager zur Lagerung einer Doppelkupplungsvorrichtung eines Doppelkupplungsgetriebes eines Kraftfahrzeuges aus, bestehend aus einem Au ßenring und einem Innenring, zwischen denen in einem Käfig aufgenommene Wälzkörper angeordnet sind, welche in Laufbahnen abrollen, welche in einer radial inneren Mantelfläche des Außenrings und in einer radial äußeren Mantelfläche des Innenrings ausgebildet sind, wobei Dichtungen in die gegenüberliegenden Mantelflächen von Außenring und Innenring eingesetzt sind, und wobei die Außenstirnseiten der Dichtungen bündig mit zugeordneten Stirnseiten von Außenring und Innenring abschließen. Zudem ist vorgesehen, dass die Wälzkörper des Stützlagers als Kugelrollen ausgebildet sind, welche mit jeweils zwei symmetrisch von einer Kugelgrundform abgeflachten sowie parallel zueinander angeordneten Seitenflächen ausgebildet sind und gegenüber dem Durchmesser ihrer Kugelgrundform eine um 15% bis 40% reduzierte Breite zwischen den Seitenflächen aufweisen.The Invention is according to the features of Hauptanspruchs therefore from a support bearing for storage of a Double clutch device of a dual-clutch transmission of a Motor vehicle consisting of an outer ring and an inner ring, between those in a cage arranged rolling elements arranged which roll in raceways, which in a radially inner lateral surface of the outer ring and in a radially outer surface of the Inner ring are formed, with seals in the opposite lateral surfaces from outer ring and inner ring are used, and wherein the outer end faces of the seals flush complete with associated end faces of outer ring and inner ring. moreover is provided that the rolling elements of the support bearing are formed as ball rollers, which with two symmetrical from a spherical base shape flattened and arranged parallel to each other faces are trained and opposite reduced the diameter of their basic ball shape by 15% to 40% Width between the side surfaces exhibit.
Durch diesen Aufbau wird vorteilhaft erreicht, dass bei ansonsten gleichen Abmessungen des Stützlagers und der Kugeldurchmesser der Nenndruckwinkel des Stützlagers deutlich erhöht werden kann. Die axiale Tragfähigkeit des Stützlagers ist dadurch wesentlich vergrößert, welches zu einer signifikanten Erhöhung der Lebensdauer führt. Durch die schmale Bauweise der Kugellrollen wird gleichzeitig auch der für Fettschmierung zur Verfügung stehende Bauraum vergrößert, wodurch die Gebrauchsdauer ebenfalls erhöht wird.By This structure is advantageously achieved that with otherwise the same Dimensions of the support bearing and the ball diameter of the nominal pressure angle of the support bearing clearly increased can be. The axial load capacity of the support bearing is thereby significantly increased, which to a significant increase the life leads. Due to the narrow design of the ball rolls is also at the same time the for Grease lubrication available increased space increases, which the service life also increased becomes.
Der
Einsatz von Kugelrollen ist auf dem Gebiet von einreihigen Radialwälzlagern
an sich bekannt. So ist aus der
Bei Untersuchungen mit erfindungsgemäßen Stützlagern haben sich einige Vorteile gegenüber herkömmlichen Stützlagern mit Lagerkugeln herausgestellt. Insbesondere konnte eine höhere Tragfähigkeit und damit eine höhere nominelle Lebensdauer erreicht werden. Letzterer Vorteil wird insbesondere durch einen größeren Schmiermittelvorrat bei gleichem Füllgrad erreicht, was einer längeren Gebrauchsdauer einhergeht. Alternativ dazu lässt sich bei gleicher Tragfähigkeit und gleicher Lebensdauer im Vergleich zu einem herkömmlichen Stützlager mit Lagerkugeln eine kürzere Baubreite des Stützlagers erreichen.at Investigations with support bearings according to the invention have some advantages over conventional ones support bearings exposed with bearing balls. In particular, a higher load capacity could and thus a higher one nominal life can be achieved. The latter advantage is in particular by a larger supply of lubricant at the same degree of filling achieves something longer Duration of use is associated. Alternatively, it can be at the same load capacity and the same life compared to a conventional one support bearings with bearing balls a shorter one Reach the width of the support bearing.
Ebenso ist aber mit der erfindungsgemäßen Ausgestaltung eines Stützlagers auch möglich, unter Beibehaltung der Baubreite den Außendurchmesser des Stützlagers zu vergrößern, welches eine Vergrößerung der Kugelrollendurchmesser ermöglicht. Durch die Durchmesservergrößerung des Stützlagers wächst die Tragfähigkeit des Lagers entsprechend exponentiell, wodurch die nominelle Lebensdauer erhöht wird. Gleichzeitig wird der Vorratsraum für das Schmiermittel vergrößert, wodurch die Gebrauchsdauer ebenfalls verlängert wird.As well but is with the embodiment of the invention a support bearing also possible, while maintaining the width of the outer diameter of the support bearing to enlarge which one an enlargement of the Ball roller diameter allows. By the diameter increase of the support bearing grows the carrying capacity the bearing accordingly exponentially, reducing the nominal life elevated becomes. At the same time the storage space for the lubricant is increased, thereby the service life is also extended.
Außerdem kann vorgesehen sein, dass die Kugelrollen als Kugelscheiben oder Ringe ausgebildet sind.
