Die
Erfindung betrifft ein Wälzlager zur Lagerung einer Welle
in einem Lenksystem, nach dem Oberbegriff des Anspruchs 1.The
The invention relates to a rolling bearing for supporting a shaft
in a steering system, according to the preamble of
Zur Lagerung von Wellen in einem Lenksystem, etwa zur Lagerung einer Lenkspindel in einem Lenkgetriebe einer Hilfskraftlenkung oder zur Lagerung einer Lenkwelle werden in bekannter Weise Wälzlager und insbesondere Rillenkugellager angewandt. Die Wälzlager sind häufig auch mit Einrichtungen zur Schwingungsentkoppelung oder zum Ausgleich von Lagerspiel ausgestattet.to Storage of waves in a steering system, such as for storage of a Steering spindle in a steering gear of a power steering system or Bearings of a steering shaft are rolling bearings in a known manner and in particular deep groove ball bearings applied. The rolling bearings are often also with facilities for vibration isolation or to compensate for bearing play.
So

Das Wälzlager ist jedoch nicht in der Lage, Spiel, welches sich durch unterschiedliche Wärmedehnung zwischen dem Aussenring und dem Innenring ergibt, auszugleichen. Zudem lässt sich mit dem Wälzlager nicht immer in ausreichender Weise auf eine damit gelagerte Welle aufgebrachte Biegemomente durch eine Schiefstellung so ausgleichen, dass ein geringes Schwenkmoment resultiert und ein Klemmen der Welle vermieden wird.The However, rolling bearing is not able to play, which due to different thermal expansion between the outer ring and the inner ring results to compensate. In addition, can be with the rolling bearing is not always sufficient on one thus mounted shaft applied bending moments due to a misalignment compensate so that a low swing torque results and a terminals the wave is avoided.

Die
Die genannten Lager sind nicht vorzugsweise geeignet, Spiel, das sich aufgrund unterschiedlicher Wärmedehnung eines Außenringes und eines Innenringes in dem Lager ergibt, zu kompensieren.The said bearings are not preferably suitable game that itself due to differential thermal expansion of an outer ring and an inner ring in the bearing results to compensate.
Der Erfindung liegt die Aufgabe zugrunde, ein Wälzlager anzugeben, dessen Radialspiel und Axialspiel unter Einfluß von Umgebungstemperaturen des Wälzlagers nicht über das Betriebsspiel ansteigt.Of the Invention has for its object to provide a rolling bearing, its radial play and axial play under the influence of ambient temperatures of the rolling bearing does not rise above the operating clearance.
Die
Aufgabe wird mit einem Wälzlager mit den Merkmalen des
Anspruchs 1 gelöst.The
Task is with a rolling bearing with the characteristics of the
Dadurch, dass zumindest ein Lagerring – der Innenring oder der Außenring – des Wälzlagers entlang einer etwa senkrecht zu der Welle verlaufenden Trennebene in zwei Ringhälften geteilt ist und die Ringhälften mit axialem Abstand zueinander mit zumindest einem Federelement gegeneinander angefedert in dem Lenksystem eingebaut sind, ist ein Wälzlager geschaffen, das in der Lage ist, eine Welle in einem Bauteil eines Lenksystems zu lagern, wobei die Lagerringe des Wälzlagers in definierter Weise radial vorgespannt sind, indem ein oder beide Lagerringe geteilt und die Ringhälften der Lagerringe axial gegeneinander gespannt sind. Eine vollkommene Kompensation von Wärmedehnungen der Lagerringe und ein gleichbleibendes Betriebsspiel des Wälzlagers ist dadurch bewirkt.Thereby, that at least one bearing ring - the inner ring or the outer ring - of Rolling bearing along a plane extending approximately perpendicular to the shaft separating plane divided into two ring halves and the ring halves with axial distance from each other with at least one spring element spring loaded against each other in the steering system is a rolling bearing created that is capable of a shaft in a component of a To store the steering system, wherein the bearing rings of the bearing are radially biased in a defined manner by one or both Split bearing rings and the ring halves of the bearing rings axially against each other are curious. A perfect compensation of thermal expansion the bearing rings and a constant operating clearance of the rolling bearing is effected by.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred Designs emerge from the dependent claims.
In einem besonders bevorzugten Ausführungsbeispiel ist der Außenring des Wälzlagers in zwei Ringhälften geteilt und beide Ringhälften mit entgegengesetzt zueinander wirkenden Federlementen gegeneinander angefedert. Die Ringhälften stützen sich an den Wälzkörpern, insbesondere an schräg zu der Längsachse des Wälzlagers verlaufenden Wälzkörperflächen ab, sodaß bei etwaiger Aufweitung der Ringhälften beispielsweise des Aussenringes, diese zwar axial aufeinander sich zubewegen, das Betriebsspiel aber dasselbe bleibt und kompensiert ist.In a particularly preferred embodiment, the outer ring of the rolling bearing is divided into two ring halves and both ring halves spring-loaded with oppositely acting Federlementen against each other. The ring halves stut zen on the rolling elements, in particular on obliquely to the longitudinal axis of the rolling bearing Wälzkörperflächen, so that at any widening of the ring halves, for example, the outer ring, while axially moving towards each other, the operating clearance but remains the same and is compensated.
Die Federelemente oder das Federelement kann aus einem elastomerem Material oder aus einem metallischen Werkstoff wie etwa Federstahl gebildet sein. Die Federelemente können beispielsweise Schraubendruckfedern sein, die in Abständen zueinander um den Umfang der Ringhälften angeordnet, sich zwischen dem Bauteil, das als Gestell für die zu lagernde Welle fungiert und den Stirnflächen der Ringhälften abstützen. Dabei federn die Schraubendruckfedern die Ringhälften des Innen – oder Aussenringes gegeneinander an.The Spring elements or the spring element may be made of an elastomeric material or formed of a metallic material such as spring steel be. The spring elements can for example helical compression springs be spaced at intervals around the circumference of the ring halves Arranged between the component, which serves as a frame for the shaft to be supported acts and the faces of the ring halves support. The helical compression springs spring the ring halves of the inner or outer ring against each other.
In einem weiteren Ausführungsbeispiel können ein oder mehrere Federelemente vorgesehen sein, die durch axial geführte Öffnungen in den Ringhälften eingreifen oder diese durchgreifen oder in anderer geeigneter Weise an den Ringhälften so festgelegt sind, daß diese durch die Zugkraft der Federelemente gegeneinander angefedert werden. Diese Ausführungsform des Wälzlagers hat den Vorteil, daß die betreffenden Ringhälften an den übrigen Bauteilen des Wälzlagers fixiert sind und das Wälzlager insgesamt leicht zu handhaben und zu montieren ist.In a further embodiment can a or a plurality of spring elements may be provided by axially guided openings engage in the ring halves or reach through this or determined in other appropriate manner to the ring halves so are that these by the tensile force of the spring elements against each other be sprung. This embodiment of the rolling bearing has the advantage that the relevant ring halves fixed to the other components of the rolling bearing and the rolling bearing as a whole are easy to handle and to assemble.
Anders als bei bekannten Schräglagern sind die betreffenden Ringhälften des Innen- oder Außenringes symmetrisch zueinander in Bezug zu der Trennebene aufgebaut. Bevorzugt sind die Wälzkörper des Wälzlagers als Kugeln gebildet und bilden ein Rillenkugellager oder ein Vierpunktlager.Different as in known oblique bearings are the relevant ring halves of the inner or outer ring symmetrical to each other in relation built up to the dividing plane. Preferably, the rolling elements of the Rolling bearing formed as balls and form a deep groove ball bearing or a four-point camp.
Es kann auch zweckmäßig sein, die Wälzkörper des Wälzlagers als Tonnen auszubilden.It may also be appropriate, the rolling elements of the rolling bearing form as tons.
Um eine in begrenztem Umfang gewünschte Kippfähigkeit des Wälzlagers zu bewirken, beispielsweise um Biegemomente in der zu lagernden Welle und deren Klemmwirkung auf das Wälzlager besser beherrschen zu können, ist in einem besonders bevorzugten Ausführungsbeispiel des erfindungsgemäßen Wälzlagers ein Ring mit balliger oder konvexer Aussenkontur um den Aussenring oder die Aussenringe des Wälzlagers gelegt. Mit Hilfe des Ringes stützt sich das Wälzlager an dem betreffenden Bauteil des Lenksystems, etwa an einer Kugelumlaufmutter ab und kann relativ zu der Kugelumlaufmutter bei Einwirkung von Biegemomenten etwa auf eine durch die Kugelumlaufmutter greifende Spindel kippen, ohne in irgendeiner Weise zu klemmen.Around a limited desired tiltability cause the rolling bearing, for example, bending moments in the shaft to be supported and its clamping effect on the rolling bearing Being able to master better is in a particularly preferred Embodiment of the invention Rolling bearing a ring with spherical or convex outer contour placed around the outer ring or the outer rings of the bearing. With the help of the ring, the rolling bearing is supported on the relevant component of the steering system, such as a ball nut and can relative to the ball nut when exposed to Bending moments approximately to a cross through the ball nut Tilt spindle without jamming in any way.
Die Kugelumlaufmutter ist Teil eines als Kugelmutter-Spindelgetriebes oder Kugelmutter-Hydrogetriebes gebildeten Lenkgetriebes. Das Lenksystem kann ein Hilfskraft- oder Fremdkraftlenksystem eines Personenkraftwagens oder Nutzkraftwagens ist.The Recirculating ball nut is part of a ball-nut spindle gearbox or ball-nut hydraulic transmission formed steering gear. The steering system can an auxiliary power or power steering system of a passenger car or commercial vehicle.
Die Erfindung wird nun näher anhand eines Ausführungsbeispiels beschrieben und anhand der beiliegenden Zeichnung wiedergegeben.The Invention will now be closer with reference to an embodiment described and reproduced with reference to the accompanying drawings.
