Abstract
Description
Die Erfindung betrifft ein Kugellager mit zwischen einem Innenring und einem Außenring angeordneten Kugeln, bei dem der Außenring in einer in einem Lagersitz zu positio nierenden Außenhülse angeordnet ist, insbesondere zur Verwendung als Lenkspindellager.The invention relates to a ball bearing with between one Inner ring and an outer ring arranged balls, at to which the outer ring is positioned in a bearing seat renal outer sleeve is arranged, in particular for Use as a steering spindle bearing.
Kugellager der vorstehenden Art sind allgemein bekannt und gebräuchlich. Grundsätzlich besteht bei solchen La gern der Wunsch, daß diese sowohl radial als auch axial möglichst spielfrei sind. Deshalb wurden zur Lagerung der Lenkspindel bisher geschliffene Präzisionslager einge setzt, die jedoch verhältnismäßig teuer sind. Billiger herzustellende Kugellager mit einer Außenhülse aus Kunst stoff können vielfach wegen der Toleranzen der Lenkspin del und des Lenkgehäuses nicht eingesetzt werden, da diese Toleranzen bei solchen Lagern zu Lagerspiel führen. Ein weiteres Hindernis für den Einsatz von Kugellagern mit Kunststoffaußenhülse liegt in den oftmals auftreten den hohen Lagerkräften, die beispielsweise in Lenkspin dellagern beim Überfahren von Bordsteinkanten mit einge schlagenen Vorderrädern auftreten.Ball bearings of the above type are generally known and common. Basically with such La gladly the wish that these are both radial and axial are as free of play as possible. Therefore, the storage of Steering spindle inserted previously ground precision bearings sets, but which are relatively expensive. Cheaper Ball bearings to be produced with an outer sleeve made of art fabric can often because of the tolerances of the steering spin del and the steering housing are not used because these tolerances lead to bearing play in such bearings. Another obstacle to the use of ball bearings with plastic outer sleeve often occurs in the the high bearing forces, for example in steering spin dell storage when driving over curbs with front wheels hit.
Der Erfindung liegt das Problem zugrunde, ein Kugellager der eingangs genannten Art so auszubilden, daß es trotz eines sehr einfachen Aufbaus möglichst spielarm in axi aler und radialer Richtung ist und hohen Belastungen standzuhalten vermag.The invention is based on the problem of a ball bearing of the type mentioned in such a way that it despite a very simple construction with as little play as possible in axi aler and radial direction and high loads able to withstand.
Dieses Problem wird erfindungsgemäß dadurch gelöst, daß der Außenring aus zwei Lagerringen besteht, welche von gegenüberliegenden Seiten jeweils mit einer schräg ver laufenden Lauffläche gegen die Kugeln anliegen und ge ringen axialen Abstand zueinander haben und daß die La gerringe durch eine Spanneinrichtung axial zueinander verspannt sind.This problem is solved according to the invention in that the outer ring consists of two bearing rings, which of opposite sides each with an oblique ver contact the running tread against the balls and ge wrestle have axial distance from each other and that the La gerrings axially to each other by a clamping device are tense.
Durch diese zweiteilige Ausbildung des Außenringes und die Spanneinrichtung erreicht man auch bei groben Tole ranzen zwangsläufig eine axiale und radiale Spielfrei heit, da durch die schrägen Laufflächen der Lagerringe die Kugeln radial nach innen bewegt werden, bis sie spielfrei gegen ihren Innenring anliegen. Das erfindungs gemäße Kugellager ist deshalb insbesondere zur Lagerung der Lenkspindel in einem Lenkgehäuse geeignet. Es vermag hohen Kräften standzuhalten und ist sehr kostengünstig herstellbar, da es teilweise aus Kunststoff gefertigt werden kann.Through this two-part design of the outer ring and the tensioning device can also be reached with large toles must inevitably have an axial and radial clearance unit because of the sloping running surfaces of the bearing rings the balls are moved radially inward until they rest against their inner ring without play. The invention appropriate ball bearing is therefore especially for storage the steering spindle in a steering housing. It can withstand high forces and is very inexpensive producible as it is partly made of plastic can be.
Die Spannvorrichtung kann sehr unterschiedlich ausgebil det sein. Besonders einfach ist sie gestaltet, wenn gemäß einer vorteilhaften Weiterbildung der Erfindung ein La gerring gegen eine axiale Schulter der Außenhülse anliegt und die Spanneinrichtung durch einen Spannring gebildet ist, welcher an der gegenüberliegenden Seite in der Au ßenhülse eingesetzt ist und mit einer Federlippe mit axi aler Vorspannung gegen den anderen Lagerring anliegt.The tensioning device can be designed in very different ways det be. It is particularly simple if according to an advantageous development of the invention a La ring against an axial shoulder of the outer sleeve and the clamping device is formed by a clamping ring which is on the opposite side in the Au outer sleeve is inserted and with a spring lip with axi aler preload against the other bearing ring.
Lenkspindeln müssen meist in einem Bereich gelagert wer den, der einen gegenüber der übrigen Lenkspindel redu zierten Durchmesser hat. Das ist auf sehr einfache Weise möglich, wenn der Innenring auf einem geschlitzten, von der Seite her über eine zu lagernde Welle oder Lenkspin del zu schiebendes Gegenlager aus elastischem Kunststoff angeordnet ist. Dieses Gegenlager setzt sich fest auf den Lagerbereich, sobald man den Innenring auf das Gegenlager aufschiebt und dieses dadurch sich im Durchmesser ver kleinert. Steering spindles usually have to be stored in one area the one that reduces one compared to the rest of the steering spindle graced diameter. It is very simple possible if the inner ring is on a slotted, by the side over a shaft or steering spin to be supported del to be pushed counter bearing made of elastic plastic is arranged. This counter bearing is firmly on the Bearing area as soon as you place the inner ring on the counter bearing postpones and this ver in diameter diminishes.
Der Spannring braucht lediglich in die Außenhülse von einer Seite her eingeschoben zu werden und verrastet dort in seiner richtigen Position, wenn gemäß einer anderen Weiterbildung der Erfindung die Außenhülse in ihrer Man telfläche radiale Durchbrechungen aufweist und der Spann ring entsprechende, in diese Durchlässe einrastbare ra dial nach außen gerichtete Rastvorsprünge hat.The clamping ring only needs to be in the outer sleeve of to be pushed in from one side and latches there in its correct position if according to another Development of the invention, the outer sleeve in their man has radial openings and the instep ring corresponding ra which can be snapped into these passages dial has outward locking projections.
Lenkgehäuse sind oftmals nicht genau zylindrisch. Das er findungsgemäße Kugellager kann sich einer toleranzbeding ten Ovalität gut anpassen, wenn auf der Außenmantelfläche der Außenhülse radial vorspringende, den Preßsitz der Au ßenhülse bewirkende Rippen vorgesehen sind.Steering boxes are often not exactly cylindrical. That he Ball bearings according to the invention can be a tolerance Adjust the ovality well if on the outer surface the outer sleeve radially projecting, the press fit of the Au Ribs causing the outer sleeve are provided.
Die axiale Positionierung des Kugellagers im Lenkgehäuse ist durch einfaches Verrasten möglich, wenn die Außen hülse zwei aus ihrer Außenmantelfläche heraus radial nach außen federnde Rastzungen aufweist.The axial positioning of the ball bearing in the steering housing is possible by simply locking when the outside sleeve two radially out of its outer surface has resilient locking tongues on the outside.
Die Erfindung läßt zahlreiche Ausführungsmöglichkeiten zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfol gend beschrieben. In ihr zeigen dieThe invention leaves numerous execution possibilities to. To further clarify their basic principle is one of them is shown in the drawing and will follow described below. They show in her

Fig. 4 eine Seitenansicht einer Außenhülse des Kugellagers, Fig. 4 is a side view of an outer sleeve of the ball bearing,
Fig. 5 einen Längsschnitt durch die Außenhülse, Fig. 5 shows a longitudinal section through the outer sleeve,
Fig. 6 eine Ansicht eines Spannringes des Kugel lagers, Fig. 6 is a view of a clamping ring of the ball bearing,
Fig. 7 einen Schnitt durch den Spannring entlang der Linie VII-VII in Fig. 6 im vergrö ßerten Maßstab. Fig. 7 shows a section through the clamping ring along the line VII-VII in Fig. 6 on an enlarged scale.
Wie die Fig. 1 zeigt, hat das erfindungsgemäße Kugella ger eine Außenhülse 1 aus Kunststoff, die an einer Stirn seite einen nach innen gerichteten Bund 2 mit einer in nenseitigen Schulter 3 hat. Gegen diese Schulter 3 liegt ein Lagerring 4 an, der eine schräge Lauffläche 5 für Ku geln 6 hat. Seitenvertauscht zu dem Lagerring 4 ist ein zweiter Lagerring 7 mit einer schrägen Lauffläche 8 in der Außenhülse 1 angeordnet. Die Laufflächen 5, 8 di vergieren zu den Kugeln 6 hin. Eine als Spannring 9 aus gebildete Spanneinrichtung stützt sich axial gegen die Außenhülse 1 ab und spannt den Lagerring 7 in Richtung der Kugel 6 und des Lagerringes 4, der dadurch spielfrei gegen die Schulter 3 gehalten wird. Auf Grund der schrä gen Laufflächen 5, 8, welche vorzugsweise unter einem Winkel von 45° verlaufen, ergibt sich durch diese axiale Vorspannung eine Kraftzerlegung in Radialrichtung. Da durch werden die Kugeln 6 radial nach innen vorgespannt, so daß sie spielfrei gegen eine rillenförmige Laufbahn 10 eines Innenringes 11 anliegen.As shown in FIG. 1, the Kugella ger according to the invention has an outer sleeve 1 made of plastic, which has an inwardly directed collar 2 with a shoulder 3 in the inside on one end face. Against this shoulder 3 is a bearing ring 4 , which has an inclined tread 5 for Ku 6 gels. Swapped to the side of the bearing ring 4 , a second bearing ring 7 with an inclined running surface 8 is arranged in the outer sleeve 1 . The treads 5 , 8 di emulate towards the balls 6 . A clamping device formed as a clamping ring 9 is supported axially against the outer sleeve 1 and clamps the bearing ring 7 in the direction of the ball 6 and the bearing ring 4 , which is thereby held against the shoulder 3 without play. Due to the oblique running surfaces 5 , 8 , which preferably run at an angle of 45 °, this axial preload results in a force decomposition in the radial direction. Since the balls 6 are biased radially inwards so that they rest against a groove-shaped raceway 10 of an inner ring 11 without play.
Die Fig. 2 und 3 zeigen ein Gegenlager 12, welches an einer Seite einen Schlitz 13 aufweist. Dadurch kann das Gegenlager 12 von der Seite her über eine zu lagernde Welle oder Lenkspindel geschoben und dann axial in die richtige Position bewegt werden. Ist das geschehen, dann schiebt man, in Fig. 2 gesehen von links her, die in Fig. 1 gezeigte Baueinheit über außenseitige Noppen 14. Dabei wird das Gegenlager 12 fest auf die Lagerstelle gespannt. Im montierten Zustand sitzt der Innenring 11 zwischen den Noppen 14 und einen umlaufenden Bund 15 nahe der den Noppen 14 gegenüberliegenden Stirnseite des Ge genlagers 12. Figs. 2 and 3 illustrate an abutment 12, which has on one side a slot 13. As a result, the counter bearing 12 can be pushed from the side over a shaft or steering spindle to be supported and then moved axially into the correct position. If this has happened, then as seen from the left in FIG. 2, the structural unit shown in FIG. 1 is pushed over knobs 14 on the outside. The counter bearing 12 is firmly clamped to the bearing point. In the assembled state, the inner ring 11 sits between the knobs 14 and a circumferential collar 15 near the opposite end of the knobs 14 of the Ge counter bearing 12th
Die Seitenansicht gemäß Fig. 4 und die Schnittdarstel lung gemäß Fig. 5 der Außenhülse 1 lassen in ihrer Man telfläche unmittelbar hinter einem Flansch 16 Durchbre chungen 17 erkennen. In diese Durchbrechungen 17 vermögen radial nach außen gerichtete, in den Fig. 6 und 7 ge zeigte Rastvorsprünge 18 des Spannringes 9 zu rasten, um diesen in der richtigen Position in der Außenhülse 1 zu fixieren.The side view according to FIG. 4 and the sectional representation according to FIG. 5 of the outer sleeve 1 show 16 breakthroughs 17 in their man surface immediately behind a flange. In these openings 17 are radially directed outwards, in FIGS . 6 and 7 ge showed locking projections 18 of the clamping ring 9 to snap to fix it in the correct position in the outer sleeve 1 .
Die Fig. 4 läßt weiterhin aus der Mantelfläche der Au ßenhülse 1 geringfügig vorspringende Rippen 19 erkennen, welche bei Einbau des Kugellagers beispielsweise im Lenk spindelgehäuse mit Preßsitz gegen die Innenmantelfläche der Lagerstelle des Lenkspindelgehäuses anliegen. Weiter hin zeigt Fig. 4 eine Rastzunge 20, die von der dem Flansch 16 gegenüberliegenden Seite her ebenfalls aus der Mantelfläche der Außenhülse 1 ragt. Fig. 4 can also be seen from the outer surface of the outer sleeve 1 slightly projecting ribs 19 which abut upon installation of the ball bearing, for example in the steering spindle housing with an interference fit against the inner surface of the bearing of the steering spindle housing. Farther Fig. 4 shows a locking tongue 20 from the flange 16 opposite side also extends out of the lateral surface of the outer sleeve 1.
Bei der Darstellung gemäß Fig. 5 wurde die Außenhülse gegenüber Fig. 4 um 90° um ihre Längsachse verdreht. Deshalb ist zu erkennen, daß insgesamt zwei Rastzungen 20, 20a vorgesehen sind. Diese vermögen in nicht gezeigte Ausnehmungen im Bereich der Lagerstelle zu rasten, um die Außenhülse 1 axial zu positionieren.In the illustration according to FIG. 5, the outer sleeve with respect to Fig was. 4 rotated 90 ° about its longitudinal axis. It can therefore be seen that a total of two locking tongues 20 , 20 a are provided. These can snap into recesses, not shown, in the region of the bearing point in order to position the outer sleeve 1 axially.
Die Schnittdarstellung gemäß Fig. 7 läßt die Gestaltung eines Rastvorsprunges 18 des Spannringes 9 erkennen. Wei terhin ist zu sehen, daß der Spannring 9 eine Federlippe 21 hat, mit der er, wie in Fig. 1 zu erkennen, gegen den Lagerring 7 mit axialer Vorspannung anliegt.The sectional view according to FIG. 7 shows the design of a locking projection 18 of the clamping ring 9 . Wei terhin can be seen that the clamping ring 9 has a spring lip 21 with which he, as can be seen in Fig. 1, bears against the bearing ring 7 with axial bias.
