Description
Die Erfindung betrifft ein Lager-Nabe-Aggregat, das die Einleitung von Druckluft in den Luftreifen eines nicht angetriebenen Rades eines Motorfahrzeugs ermöglich.The The invention relates to a bearing-hub-unit, the introduction of compressed air in the pneumatic tire of a non-driven wheel of a motor vehicle allows.
Bekannt sind Lager-Nabe-Aggregate, die das Einleiten oder Einblasen von Druckluft aus einer am Fahrzeug angebrachten Druckluftquelle in den Luftreifen gestatten, um den Luftdruck in den Luftreifen zu regeln und/oder zu überwachen.Known are bearing-hub aggregates that allow the introduction or injection of Compressed air from a compressed air source mounted on the vehicle allow the pneumatic tire to increase the air pressure in the pneumatic tire regulate and / or monitor.

Bei den beiden oben erwähnten Fällen erfolgt die Drucklufteinleitung in unmittelbarer Nachbarschaft der Wälzkörper des Lager-Nabe-Aggregats, so dass es erforderlich wird, besondere Hochleistungs-Dichtungen einzubauen, um zu verhindern, dass die Druckluft unmittelbar in die inneren Teile des Lagers eindringt, wo das Schmierfett für die Wälzkörper enthalten ist. Diese Dichteinrichtungen sind kostspielig und erzeugen eine beträchtliche Reibung. Außerdem kann der Durchtritt von Druckluft durch das Lager dessen Lebensdauer erheblich verkürzen, falls die vorerwähnten Dichteinrichtungen schadhaft sind oder schadhaft werden. Dazu kommt, dass diese Einrichtungen gewöhnlich in der Nähe der Laufbahnen des Lagers angebracht sind und daher wegen des in diesen Bereichen äußerst knappen verfügbaren Raumes miniaturisiert werden müssen.at the two mentioned above make the compressed air is introduced in the immediate vicinity of Rolling elements of the Bearing hub aggregate so it will require special high performance gaskets To prevent the compressed air from directly entering the inner parts of the bearing penetrates where the grease for the rolling elements contain is. These sealing devices are expensive and produce a considerable Friction. Furthermore can the passage of compressed air through the bearing its life shorten considerably, if the aforementioned Sealing devices are damaged or become defective. In addition, that these facilities usually near the raceways of the bearing are mounted and therefore because of in this Areas extremely tight available Space must be miniaturized.
