RadlagerdichtungWheel bearing seal

Die Neuerung betrifft eine Radlag er dichtung aus elastischem Werkstoff, für insbesondere Kegelrollenlager, bestehend aus einem versteiften Haftteil, einer damit verbundenen, vorzugsweise federbelasteten Dichtlippe und einer Staubschutzlippe, wobei der Haftteil auf dem Außenring des Lagers aufgezogen ist.The innovation concerns a wheel bearing seal made of elastic material, For tapered roller bearings in particular, consisting of a stiffened adhesive part, a preferably spring-loaded sealing lip connected to it and a dust protection lip, the adhesive part being pulled onto the outer ring of the bearing.

Im Kraftfahrzeugbau sind die Räder mit ihren Radnaben im Achsgehäuse mittels Wälzlagern vorzugsweise Kegelrollenlagern abgestützt. Zur Abdichtung dieser Lager wurden bisher normale Wellendientringe verwendet, die aber wegen ihrer relativ großen Einbaubabmes sungen bzw. ihrer schwierigen Demontagemöglxchkeit nur ungern eingebaut wurden. Demzufolge wurde bereits vorgeschlagen, zur Abdichtung des Rollenlagers einen elastischen Dichtungsring zu verwenden, dessen Manschetten* teil durch einen metallischen Ring, dessen lichter Durchmesser auf der Lagerseite kleiner als der Außendurchmesser des Rollenkäfigs ist, versteift ist. Solche Dichtungen bestehen aus einer, das Lager abdichtenden federbelasteten Dichtlippe, sowie einer nach außen hin wirkenden Staubschutzlippe. Beide Lippen laufen dabei auf einem Bund des Lagerzapfens, der entsprechend gehärtet und im Einstichverfahren geschliffen sein muß*·In automotive engineering, the wheels are in the axle housing with their wheel hubs preferably tapered roller bearings supported by means of roller bearings. Normal shaft service rings were previously used to seal these bearings used, but because of their relatively large Einbaubabmes solutions or their difficult dismantling possibility were only reluctantly installed. As a result, it has already been proposed to use an elastic sealing ring to seal the roller bearing, the sleeves of which * part stiffened by a metallic ring, the inner diameter of which on the bearing side is smaller than the outer diameter of the roller cage is. Such seals consist of a spring-loaded sealing lip that seals the bearing and a dust protection lip that acts on the outside. Both lips run on a collar of the bearing journal, which must be suitably hardened and ground using the plunge-cut method *

Bei einer anderen bekannten Abdichtung eines Kugellagers sind der Innen- und Außenring des Lagers entsprechend verlängert, so daß zwischen beiden ein normaler Wellendich.tring eingebaut werden kann. Der Wellendichtung sitzt dabei mit seinem Haftteil fest im Außenring des Lagers, während die Dichtlippe auf dem Innenring des Lagers gleitet.In another known seal of a ball bearing, the inner and outer ring of the bearing are extended accordingly, so that between Both a normal shaft sealing ring can be installed. Of the The shaft seal sits firmly with its adhesive part in the outer ring of the Bearing while the sealing lip slides on the inner ring of the bearing.

Bei Ausnutzung dieses Vorteils soll eine Radlag er dichtung gefunden werden, die insbesondere bei einer doppellippigen Ausführung keine wesentliche axiale Verlängerung des Lagerkörpers benötigt.When taking advantage of this advantage, a wheel bearing seal should be found that is not essential, especially in the case of a double-lipped design axial extension of the bearing body required.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, daß die Dichtlippe der Dichtung in an sich bekannter Weise auf dem Innenring des Lagers und die Staubschutzlippe auf dem als Anschlag für den Innenring des Lagers dienenden Wellenbund dichtend aufliegen. Die Dichtung wird in an sich bekannter Weise über ihr Haftteil am Außenring des Rollenlagers befestigt. Die die eigentliche Lagerabdichtung übernehmende, scharfkantige Dichtlippe läuft dabei auf einer nur geringfügig in axialer Richtung verlängerten Umfangsflache des Innenringes des Lagers, während die Staubschutzlippe bereits auf dem axial hinter dem Lager folgenden Wellenbund dichtend aufliegt. Infolge keiner oder einer geringen Spannung, die der Staub schutz lippe innewohnt, sowie infolge des abgerundeten Berührung s quer schnitt es mit dem Lagerzapfen braucht letzterer nicht mehr gehärtet und geschliffen zu sein.This object is achieved according to the invention in that the sealing lip the seal in a manner known per se on the inner ring of the bearing and the dust protection lip on the as a stop for the inner ring of the bearing serving the shaft collar. The seal is in a manner known per se via its adhesive part on the outer ring of the roller bearing attached. The sharp-edged sealing lip, which takes on the actual bearing seal, runs only slightly in the axial direction Direction of the extended peripheral surface of the inner ring of the bearing, while the dust protection lip already on the following axially behind the bearing The shaft collar rests in a sealing manner. As a result of little or no tension inherent in the dust protection lip, and as a result of the rounded shape Contact s cross cut it with the bearing pin needs the latter not to be hardened and ground anymore.

Ein Ausführungsbeispiel einer neuerungsgemäßen Radlagerdichtung ist in der Zeichnung dargestellt und wird wie folgt beschrieben:One embodiment of a wheel bearing seal according to the invention is shown in the drawing and is described as follows:

Zwischen der Radnabe 1 und dem Lagerzapfen 2 ist das aus den Kegelrollen 3, dem Außenring 4 und dem Innenring 5 bestehende Kegelrollenlager eingebaut. Der Außenring 4 des Lagers weist eine Ausnehmung 6 auf, die zur Aufnahme des Haftteiles 7 der Lagerabdichtung dient. Die im wesentlichen aus einem elastischen Werkstoff gebildete Dichtung besitzt außer ihrem zylindrischen Haftteil 7 einen radial nach innen verlaufenden Verbindung steil 8, aus dessen radial innerem Ende die Dichtlippe 9 und die Staubschutzlippe 10 herausgebildet sind. Die Dichtlippe wird zusätzlich von einem Schraubenzugfederring 11 belastet und gleitet mit ihrer Dichtkante 12 auf der äußeren Umfangsfläche 13 des Innenringes 5 des Lagers. Die Staubschutzlippe 10 läuft dabei auf dem als An· schlag für den Innenring 5 des Lagers dienenden Wellenbund 13. Im eingebauten Zustand wird vielfach der zwischen der Dichtlippe 9 und der Staub schutz lippe 10 gebildete Raum 14 mit Schmierfett gefüllt.Between the wheel hub 1 and the journal 2 is that from the tapered rollers 3, the outer ring 4 and the inner ring 5 installed existing tapered roller bearings. The outer ring 4 of the bearing has a recess 6 on, which serves to accommodate the adhesive part 7 of the bearing seal. The seal formed essentially from an elastic material has in addition to its cylindrical adhesive part 7 a radially inwardly extending connection steep 8, from the radially inner end of the sealing lip 9 and the dust protection lip 10 are formed. The sealing lip is additionally loaded by a helical tension spring ring 11 and slides with its sealing edge 12 on the outer peripheral surface 13 of the inner ring 5 of the camp. The dust protection lip 10 runs on the built-in shaft collar 13 serving as a stop for the inner ring 5 of the bearing State is often the space 14 formed between the sealing lip 9 and the dust lip 10 is filled with grease.
