Description
Wälzlager, insbesondere Drucklager für die Ausrückhebel einer Kraftfahrzeugkupplung Die Erfindung bezieht sich auf ein Wälzlager, insbesondere Drucklager für die Ausrückhebel einer Kraftfahrzeugkupplung, mit einem Schmierkörper, der ringförmig ausgebildet ist, konzentrisch zur Lagerachse liegt und seitlich an den umlaufenden Wälzkörpern anliegt.Rolling bearings, in particular thrust bearings for the release levers of a motor vehicle clutch The invention relates to a roller bearing, in particular a thrust bearing for the release lever a motor vehicle clutch, with a lubricating body, which is annular is, is concentric to the bearing axis and laterally on the rotating rolling elements is present.
Es ist bekannt, den ringförmigen Schmierkörper als gefetteten Filzring auszubilden. Das hat jedoch den Nachteil, daß ein Teil des für das Schmiermittel zur Verfügung stehenden Raumes von dem Filzring eingenommen wird. Aufgabe der Erfindung ist es, diesen Nachteil zu vermeiden, so daß unter Beibehaltung derLagerabmessungen eine erheblich größere Schmiermittelmenge in dem Lager untergebracht werden kann.It is known to use the annular lubricating body as a greased felt ring to train. However, this has the disadvantage that a part of the for the lubricant available space is taken up by the felt ring. Object of the invention is to avoid this disadvantage, so that while maintaining the bearing dimensions a considerably larger amount of lubricant can be accommodated in the bearing.
Gemäß der Erfindung wird daher vorgeschlagen, daß der Schmierkörper aus einem vorwiegend aus Fett von feinster Konsistenz bestehenden Preßling besteht. Dies hat unter anderem folgende Vorteile: Es wird nur ein einziges Material, nämlich Fett, benötigt. Das Fett kann hart sein, während zum Tränken des Filzringes und zum Fließen aus dem Filzring an die Wälzkörper ein verhältnismäßig weiches Fett verwendet werden muß, was den Nachteil hat, daß das Fett leichter aus dem Lagergehäuse entweichen kann. Ferner kann bei dem Wälzlager gemäß der. Erfindung bei gleichem Platzaufwand mehr Fett untergebracht werden. Dieser Gesichtspunkt ist sehr wichtig, weil die erfindungsgemäße Schmierung in erster Linie bei solchen Lagern Anwendung finden soll, die schlecht zugänglich ' sin"d--und die während der Lebensdauer der Maschine nicht oder nur sehr selten mit neuem Schmiermittel versehen werden sollen. Obwohl ein Schmierstoff von fester Konsistenz verwendet wird, so daß ein Auslaufen des Schmierstoffes aus dem Lager nicht zu befürchten ist, ist doch eine ausreichende Schmierung deshalb gewährleistet, weil die Erschütterungen der umlaufenden, zu schmierenden Wälzkörper bewirken, daß diese immer wieder an den Schmierstoffpreßling anlaufen und dadurch den zur Schmierung notwendigen Schmierfilm aufgetragen erhalten.According to the invention it is therefore proposed that the lubricating body consists of a compact consisting mainly of fat of the finest consistency. Among other things, this has the following advantages: There is only one single material, namely Fat, needed. The grease can be hard while soaking the felt ring and a relatively soft grease to flow from the felt ring to the rolling elements must be used, which has the disadvantage that the fat more easily from the bearing housing can escape. Furthermore, in the rolling bearing according to FIG. Invention with the same Space required to accommodate more fat. This point of view is very important because the lubrication according to the invention is primarily used in such bearings is supposed to find the poorly accessible 'sin "d - and those during the life of the Machine should not be provided with new lubricant or only very rarely. Although a lubricant of solid consistency is used, so there is no leakage of the lubricant from the bearing is not to be feared, it is still sufficient Lubrication is guaranteed because of the vibrations of the rotating, to be lubricated Rolling bodies have the effect that they repeatedly run against the lubricant pressed part and thereby the lubricating film required for lubrication is applied.
Vorteilhaft ist es, wenn der äußere Wälzlagerring und der Schmierstoffpreßling von einem Blechmantel umfaßt sind.It is advantageous if the outer rolling bearing ring and the lubricant pressed part are encompassed by a sheet metal jacket.
In weiterer Ausgestaltung der Erfindung wird für das Drucklager für die Ausrückhebel einer Kraftfahrzeugkupplung vorgeschlagen, daß der ringförmige, innere Lagerteil in an sich bekannter Weise einstückig ausgebildet ist, während der äußere, umlaufende Lagerteil aus dem äußeren Wälzlagerring, einem auf der einen Seite an diesen anliegenden Druckring zum Abstützen der Ausrückhebel und dem auf der anderen Seite an den äußeren Wälzlagerring anliegenden Schmierstoffpreßling besteht, die sämtlich von dem Blechmantel in gleichfalls bekannter Weise zusammengehalten werden.In a further embodiment of the invention is for the thrust bearing for the release lever of a motor vehicle clutch proposed that the annular, inner bearing part is formed in one piece in a manner known per se, while the outer, circumferential bearing part from the outer rolling bearing ring, one on the one Side on this pressure ring to support the release lever and the on the other side of the lubricant pressed against the outer rolling bearing ring consists, all of which are held together by the sheet metal jacket in a likewise known manner will.
Der Schmierstoffpreßling kann mit Axialspiel in den Blechmantel eingelegt, und der sich radial erstreckende Teil des Mantels kegelstumpfförmig ausgebildet sein, damit sich der Schmierstoffpreßling axial gegen die Wälzkörper anlegt und diese gut schmiert.The compacted lubricant can be inserted into the sheet metal jacket with axial play, and the radially extending portion of the shell is frustoconical be so that the lubricant pressed axially rests against the rolling elements and this lubricates well.
Der Schmierstoffpreßling kann aber auch durch eine Druckfeder in axialer Richtung belastet sein, die ihn an die Wälzkörper anpreßt. Es wird also beim Herstellen des Schmierstoffpreßlings darauf ankommen, ihn aus solchen Bestandteilen zusammenzuschmelzen, die eine gute Lagerschmierung bei geringem Abrieb je Wellenumdrehung gewährleisten.The lubricant compact can, however, also be axially supported by a compression spring Be loaded in the direction that presses him against the rolling elements. So it becomes when manufacturing of the compressed lubricant depends on melting it together from such components, which ensure good bearing lubrication with little wear per shaft revolution.
Bei einer anderen Bauart ist der Blechmantel im Bereich des Schmierstoffpreßlings kegelig ausgebildet, so daß dieser infolge der durch die Fliehkraft im Zusammenwirken mit der schrägen Auflage erzeugten axialen Schubkraft an die Wälzkörper angelegt wird.In another design, the sheet metal jacket is in the area of the pressed lubricant conical, so that it interacts as a result of the centrifugal force with the inclined support generated axial thrust applied to the rolling elements will.
In den Zeichnungen sind Längsschnitte von verschiedenen Ausführungsbeispielen gemäß der Erfindung dargestellt: Fig. 1 veranschaulicht ein Wälzlager mit einem fest ins Gehäuse eingesetzten Schmierstoffpreßling, Fig. 2 ein Wälzlager mit einem lose in das Gehäuse eingesetzten, sich unter der Einwirkung der Schwerkraft an die Wälzkörper anlegenden Schmierstoffpreßfing, Fig. 3 ein Wälzlager mit einem unter Federspannung stehenden Schmierstoffpreßling und Fig. 4 ein Wälzlager mit einem sich unter der Einwirkung der Fliehkraft axial an die Wälzkörper anliegenden Schmierstoffpreßling.In the drawings are longitudinal sections of various exemplary embodiments illustrated according to the invention: Fig. 1 illustrates a rolling bearing with a Firmly inserted lubricant compact in the housing, Fig. 2 shows a roller bearing with a loosely inserted into the housing, under the action of gravity to the Lubricant pressfing applying to rolling elements, 3 shows a roller bearing with a compressed lubricant under spring tension and FIG. 4 shows a roller bearing with a bearing axially against the rolling elements under the action of centrifugal force Lubricant compact.

Der Druckring 2 b wird beim Ausrücken der Kupplung in Richtung des Pfeiles A belastet. Der äußere Wälzlagerring 7 befindet sich zwischen dem Druckring 5, an den sich der Ausrückhebel 4- anlegt, und dem ringförmigen Schmierstoffpreßling 6,-. alle drei Teile werden durch den Blechmantel $ zusammengehalten, dessen ringförmiger Mantelteil 8 a sieh am äußeren Ende radial in Richtung zum inneren Lagerteil 2 hin erstreckt.The inner bearing part 2 is axially displaceable on the shaft 1 and the rolling elements 3 (balls) roll on its raceway 2a. The pressure ring 2 b is loaded in the direction of arrow A when the clutch is disengaged. The outer roller bearing ring 7 is located between the pressure ring 5, on which the release lever 4 is applied, and the annular lubricant pressed part 6, -. all three parts are held together by the sheet metal jacket $ whose annular jacket part 8 a see extends radially towards the inner bearing part 2 at the outer end.
Beim Gegenstand der Fig. 2 ist der Mantelteil 8a schräg nach innen abgewinkelt. Der Schmierstoffpreßling 6 sitzt lose =im Blechmantel 8 und liegt infolge seines Gewichtes und des schrägen Verlaufes des radialen Mantelteiles 8 a - der fortschreitenden Abnützung des Schmierstoffpreßlings 6 folgend - stets auf den Wälzkörpern 3 des Wälzlagers auf.In the subject of FIG. 2, the jacket part 8a is inclined inwards angled. The lubricant pressed part 6 sits loosely = in the sheet metal jacket 8 and lies as a result its weight and the oblique course of the radial shell part 8 a - the following progressive wear of the lubricant pressed part 6 - always on the rolling elements 3 of the rolling bearing.
Beim Gegenstand der Fig. 3 steht der Schmierstoffpreßling 6 unter der Spannung der Druckfeder 9, die ihn an die Wälzkörper 3 anpreßt.In the subject of FIG. 3, the lubricant pressed part 6 is below the tension of the compression spring 9, which presses it against the rolling elements 3.
Beim Gegenstand der Fig.4 bewirkt die Kegelfläche 8 b des Mantels 8, daß der sich drehende Schmierstoffpreßling 6 stets an den Wälzkörpern 3 anliegt. Die Fliehkräfte üben auf den Schmierstoffpreßling 6 eine axial gerichtete Schubkraft S aus.When the subject of Figure 4 causes the conical surface 8 b of the shell 8, that the rotating lubricant compact 6 is always in contact with the rolling elements 3.
