Abstract
Description
Die Erfindung betrifft eine insbesondere für Anhängerachsen bestimmte Radlagerung mit einer mittels eines vorderen und eines hinteren Wälzlagers drehbar auf einem Achsschenkel gelagerten Nabe, an der ein Rad befestigbar ist, wobei zwischen den Innenringen des vorderen und des hinteren Wälzlagers eine den Achsschenkel umgebende Hülse angeordnet ist.The invention relates in particular for trailer axles certain wheel bearings with one by means of a front and one rear roller bearing rotatable Hub supported on a steering knuckle, to which a wheel can be attached is, between the inner rings of the front and rear roller bearing a sleeve surrounding the steering knuckle is arranged.
Eine solche Radlagerung mit innerem
und äußerem Wälzlager,
die sich jeweils aus einem Innenring, einem Außenring und den Wälzkörpern zusammensetzen,
ist aus der
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Radlagerung der eingangs genannten Art derart weiterzubilden, daß trotz einer möglichen axialen Veränderung des Abstandes der Wälzlager zueinander einerseits das Austreten von Schmierstoff aus einem Schmierstoffvorrat und andererseits das Eindringen von Fremdstoffen in den Schmierbereich verhindert wird.The invention has for its object a Wheel bearings of the type mentioned in such a way that despite one possible axial change the distance between the rolling bearings on the one hand the lubricant escaping from a lubricant supply and on the other hand the penetration of foreign substances into the lubrication area is prevented.
Zur Lösung dieser Aufgabenstellung ist erfindungsgemäß die Hülse als in axialer Richtung des Achsschenkels biegeelastische Hülse ausgebildet.To solve this task is the sleeve according to the invention as Elastic sleeve formed in the axial direction of the steering knuckle.
Durch diese vollständige Rückverformbarkeit der Hülse in axialer Richtung ist es bei der erfindungsgemäßen Radlagerung möglich, daß die Hülse nicht nur den gesamten axialen Abstand zwischen dem vorderen und dem hinteren Wälzlager abdeckt, sondern sich die Wälzlager im Betrieb oder bei der Montage der Radlagerung voneinander wegbewegen können, ohne daß dadurch ein Freiraum zwischen den Wälzlagern entsteht, in den Schmutzpartikel eintreten können.Due to this complete reshapability of the Sleeve in Axial direction, it is possible in the wheel bearing according to the invention that the sleeve is not only the total axial distance between the front and the rear roller bearing covers, but the rolling bearings move away from each other during operation or when installing the wheel bearing can, without this a space between the roller bearings arises, into which dirt particles can enter.
Zur Erzielung einer Elastizität, bei der die Hülse auch bei vom Achsschenkel abgezogener Radlagerung an beiden Wälzlagern zugleich anliegt, können in bevorzugter Weise an der Hülse einzelne vorgegebene Biegebereiche ausgebildet sein. Durch die Vorgabe bestimmter Biegebereiche ist es durch geeignete Materialauswahl und/oder geometrische Ausgestaltung der Hülse möglich, das Maß der Biegeelastizität der Hülse genau vorherzubestimmen.To achieve an elasticity in which the sleeve even with the wheel bearing removed from the steering knuckle on both roller bearings at the same time, can preferably on the sleeve individual predetermined bending areas can be formed. By default It is certain bending areas through suitable material selection and / or geometric design of the sleeve possible, the degree of bending elasticity of the sleeve exactly predict.
Gemäß einer praktischen Ausführungsform der Erfindung weist die Hülse wenigstens zwei Teilbereiche mit jeweils unterschiedlichen Durchmessern auf, wobei diese Teilbereiche über einen Übergangsbereich miteinander verbunden sind, der im Längsschnitt S-förmig ausgebildet ist. Dieser S-förmige Übergangsbereich bildet den definierten Biegebereich der Hülse, da sich im Bereich dieser S-förmigen Wellenstruktur die einzelnen Teilbereiche der Hülse in Axialrichtung des Achsschenkels gegeneinander verschieben können.According to a practical embodiment of the Invention has the sleeve at least two sub-areas, each with different diameters on, with these subareas about a transition area are interconnected, the S-shaped in longitudinal section is. This S-shaped transition area forms the defined bending area of the sleeve, because in the area of this S-shaped Wave structure the individual sections of the sleeve in the axial direction of the steering knuckle can move against each other.
Die Biegeelastizität der Hülse kann bei dieser Ausgestaltung dadurch verstärkt werden, daß die Hülse zumindest im S-förmigen Übergangsbereich mindestens einen radial umlaufenden Bereich mit einer reduzierten Materialwandstärke aufweist. Durch diese Reduzierung der Materialwandstärke im Bereich des S-förmigen Übergangsbereichs wird die Biegeelastizität der Hülse bei einer auftretenden Axialbelastung deutlich erhöht, wodurch auch die Gefahr einer unerwünschten, bleibenden Verformung der Hülse bei einer Axialverschiebung der Wälzlager aufeinander zu minimiert wird.The bending elasticity of the sleeve can be reinforced in this embodiment in that the sleeve at least at least in the S-shaped transition area has a radially circumferential area with a reduced material wall thickness. This reduction in the material wall thickness in the area of the S-shaped transition area becomes the bending elasticity the sleeve with an occurring axial load significantly increased, whereby also the risk of unwanted, permanent deformation of the sleeve minimized in the event of an axial displacement of the rolling bearings becomes.
Schließlich wird mit der Erfindung vorgeschlagen, daß auf der äußeren Mantelfläche der Hülse auf einer umlaufenden Kreisbahn radial nach außen vorstehende Nocken zur Anlage an einem mit dem Außenring des hinteren Wälzlagers verbundenen Fettfangblech ausgebildet sind.Finally, with the invention suggested that on the outer surface of the Sleeve on a circumferential circular path radially projecting cams Attachment to one with the outer ring of the rear rolling bearing connected grease trap are formed.
Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung hält die Hülse in Zusammenspiel mit der Nabe oder Mitteln wie einem Fettfangblech, einer Ablaufsicherung, einer Dichtung oder dergleichen, Schmierfett im Bereich der Wälzlager. Dadurch läßt sich die zu befüllende Schmierfettmenge reduzieren und für eine längere Zeit im Bereich der Wälzlager halten.According to a particularly advantageous embodiment of the invention, the sleeve holds together mens play with the hub or means such as a grease trap, a drain safety device, a seal or the like, grease in the area of the rolling bearings. This allows the amount of grease to be filled to be reduced and kept in the area of the roller bearings for a longer period of time.
