Abstract

The ball or roller bearing to support vehicle wheels which are fitted on the inner race of the bearing with a brake drum or brake disc, has holes in an extension of the inner race which act like a radial-flow fan when the wheel revolves. The air flow induced thereby is directed against the wheel bearing and into passages at the back of the brake disc to cool bearing and brake. The inner race (16) of the ball bearing (6) has holes (15) in the flange (4) carrying the brake disc (3) and the wheel (1) which act like a radial fan. The induced air flow (17) partly cools the brake disc through passages (5) and partly the outer race (7). The lubricating oil supply (13) for the homekinetic coupling (11) of drive shaft (14) to inner race communicates through holes (18) with the oil reservoir (8) of the bearing (6). This effects a pressure lubrication at a pressure which rises with the square of the wheel speed.

Description

Wälzlager zur Lagerung von Rädern, die mit Rolling bearings for the storage of wheels with

einer Bremsvorrichtung versehen sind Die Erfindung betrifft ein Wälzlager zur Lagerung von Rädern, die mit einer Bremsvorrichtung versehen sind, deren Bremsscheibe oder Bremstrommel am Innenring des Wälzlagers befestigt ist. a braking device are provided. The invention relates to a roller bearing for the storage of wheels which are provided with a braking device, their brake disc or brake drum is attached to the inner ring of the rolling bearing.

Der Erfindung liegt die Aufgabe zugrunde, das bis jetzt noch nicht zufriedenstellend gelöste Problem des Abführens der Bremswärme bei einer auf einen möglichst kleinen Einbauraum zusammengedrängten Antriebseinheit für die Räder eines Kraftfahrzeuges, bei der die Bremsscheibe am Innenring des Wälzlagers zur Lagerung des Rades befestigt ist und zusammen mit der Gleichlaufgelenkkupplung aum Antrieb des Rades eine bauliche Einheit bildet, mit einfachen, raum- und kostensparenden Mitteln zu lösen.The invention is based on the object that has not yet been achieved problem solved satisfactorily of the dissipation of the braking heat in one to one Smallest possible installation space crowded drive unit for the wheels of a Motor vehicle in which the brake disc on the inner ring of the roller bearing for storage of the wheel is attached and together with the constant velocity joint aum drive of the wheel forms a structural unit with simple, space- and cost-saving Funds to solve.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Innenring des Wälzlagers mit Durchbrüchen versehen ist, durch die bei Rotation die Wirkung eines Radialgebläses zustandekommt, dessen Luftströme ein Aufheizen des Wälzlagers durch die Bremswärme verhindern.According to the invention, this object is achieved in that the inner ring of the roller bearing is provided with openings through which the effect during rotation a radial fan comes about, the air streams of which heat the roller bearing prevent by the brake heat.

Nach einer bevorzugten Ausführungsform der Erfindung ist das Wälzlager, wie an sich bekannt, in die Gleichlaufgelenkkupplung zum Antrieb des Rades integriert und der Schmiermittelvorrat des Wälzlagers ist mit dem Schmiermittelvorrat der Gleichlaufgelenkkupplung über eine oder mehrere Bohrungen verbunden, sodass bei Rotation eine Druckschmierung des Wälzlagers zustandekommt, deren Schmiermitteldruck mit dem Quadrat der Drehzahl des Rades ansteigt.According to a preferred embodiment of the invention, the roller bearing is as known per se, integrated into the constant velocity joint coupling to drive the wheel and the lubricant supply of the rolling bearing is equal to the lubricant supply of the constant velocity joint connected via one or more bores, so that a pressure lubrication during rotation of the rolling bearing comes about, the lubricant pressure of which with the square of the speed of the wheel increases.

Die Die technischen und wirtschaftlichen Vorteile der Erfindung sind aus der Zeichnung erkennbar, die zeigt,dass die durch die erfindungsgemässe Ausbildung des Wälzlagers zustandekommende Kühlwirkung ein unmittelbares Heranrücken des wärmeempfindlichen Wälzlagers, welches in die ebenfalls wärmeempfindliche Gleichlaufgelenkkupplung integriert ist, an die sich manchmal bis zur Rotglut erwärmende Bremsscheibe erlaubt, sodass es möglich ist, eine besonders rationelle bauliche Einheit zum Antrieb der Vorderräder eines Kraftfahrzeuges zu schaffen, die kleiner, leichter und billiger ist als die bis jetzt bekanntgewordenen Vorschläge für solche Antriebseinheiten.the The technical and economic advantages of the invention can be seen from the drawing, which shows that the inventive Formation of the rolling bearing resulting cooling effect a direct approach of the heat-sensitive roller bearing, which is inserted into the also heat-sensitive constant velocity joint is integrated, on which the brake disc, which sometimes heats up to the red heat, allows so that it is possible to use a particularly rational structural unit to drive the To create front wheels of a motor vehicle that are smaller, lighter and cheaper is considered to be the proposals for such drive units that have become known up to now.

Das erfindungsgemässe Wälzlager 6 hat einen Innenring 16, welcher mit Durchbrüchen 15 versehen ist, durch die bei Rotation die Wirkung eines Radialgebläses zustandekommt, dessen Luftströme 17 ein Aufheizen des Wälzlagers 6 durch die Bremswärme verhindern, sodass die sich manchmal bis zur Rotglut erwärmende Bremsscheibe 3, welche mittels der Schrauben 2 zusammen mit dem Rad 1 am Flansch 4 des Innenringes 16 befestigt ist, ganz nane und platzsparend an das Wälzlager 6 herangerückt werden kann. Das B lzlager 6, dessen Aussenring 7 mittels der Schrauben 10 am Radträger 9 befestigt ist, ist in die Gleichlaufgelenkkupplung 11 integriert, deren Schmiermittelvorrat 13 über eine oder mehrere Bohrungen 18 mit dem Schmiermittelvorrat 8 des Wälzlagers verbunden ist, sodass bei Rotation eine Druckschmierung des Wälzlagers 6 zustandekommt, deren Schmiermitteldruck mit dem Quadrat der Drehzahl des Rades ansteigt. Diese wirkungsvolle und auf einfache Weise zustandekommende Schmierung ergibt zusammen mit der Luftkühlung eine besonders lange Lebensdauer des Wälzlagers 6, welches über die Dichtelemente 20 und 21 mit einer dem Überdruck der Druckschmierung Rechnung tragenden Sicherheit abgedichtet ist.The roller bearing 6 according to the invention has an inner ring 16 which is provided with openings 15 through which the action of a radial fan when rotating comes about whose air flows 17 a heating of the roller bearing 6 by the braking heat prevent the brake disc 3, which sometimes heats up to the red heat, which by means of the screws 2 together with the wheel 1 on the flange 4 of the inner ring 16 is attached, are moved very nane and space-saving to the roller bearing 6 can. The ball bearing 6, its outer ring 7 by means of the screws 10 on the wheel carrier 9 is attached, is integrated into the constant velocity joint 11, the lubricant supply 13 via one or more bores 18 with the lubricant supply 8 of the roller bearing is connected, so that pressure lubrication of the roller bearing 6 occurs during rotation, whose lubricant pressure increases with the square of the speed of the wheel. These effective and easily achieved lubrication results together with the air cooling a particularly long life of the roller bearing 6, which over the sealing elements 20 and 21 with the overpressure of the pressure lubrication account bearing security is sealed.

Die Abdichtung des Schmiermittelvorrats 13 erfolgt huber die Antriebswelle 14, die Dichtungsmanschette 12 und die Verschlusskappe 19. Zur Erhöhung der Kühiwirkung sind die Durchbrüche 15 des Innenringes 16 des Wälzlagers 6 au die zur Kühlung der Bremsscheibe vorgesehenen Durchbrüche 5 hin ausgerichtete ?atentansprüche: LeerseiteThe lubricant supply 13 is sealed off via the drive shaft 14, the sealing collar 12 and the sealing cap 19. To increase the cooling effect are the openings 15 of the inner ring 16 of the roller bearing 6 au for cooling the Brake disc provided breakthroughs 5 aligned? Blank page
