Abstract

The invention relates to a mounting of a shaft in a housing, in particular of a steering column in a supporting tube of a motor vehicle, by means of two angular contact ball bearings (1) that are braced with respect to each other by means of a spring, the inner rings (4) of said angular contact ball bearings being guided on the shaft by means of supporting elements, wherein the supporting elements are supported on retaining elements fixed to the shaft. According to the invention, the spring comprises at least one spring tongue (6), which is integrally moulded on the inner ring (4) and/or outer ring (2) of at least one of the angular contact ball bearings (1).

Description

Bezeichnung der Erfindung  Name of the invention
Lenksäulenlagerung für Kraftfahrzeuge Beschreibung Steering column bearing for motor vehicles Description
Gebiet der Erfindung Field of the invention
Die Erfindung betrifft eine Lagerung einer Welle in einem Gehäuse, insbeson- dere einer Lenksäule in einem Tragrohr eines Kraftfahrzeuges, mittels zweier gegeneinander mittels einer Feder verspannter Schrägkugellager, deren Innenringe mittels Stützelementen auf der Welle geführt sind, wobei die Stützelemente sich an auf der Welle befestigten Haltelementen abstützen. Hintergrund der Erfindung The invention relates to a bearing of a shaft in a housing, in particular a steering column in a support tube of a motor vehicle, by means of two biased by a spring angular contact ball bearings whose inner rings are guided by means of support elements on the shaft, wherein the support elements attached to on the shaft Support holding elements. Background of the invention
Durch eine ausgeführte Lenksäulenlagerung der Anmelderin ist es bekannt, den Innenring eines Schrägkugellagers auf einem Stützelement zu befestigen, wobei zwischen dem Stützelement und dem Halteelement eine Feder eingebaut ist, die das Stützelement in Richtung Innenring des Schrägkugellagers belastet. By an executed steering column bearing the applicant, it is known to attach the inner ring of an angular contact ball bearing on a support member, wherein between the support member and the holding element, a spring is installed, which loads the support member in the direction of the inner ring of the angular contact ball bearing.
Bei der Lenksäulenmontage ergibt sich dadurch jedoch das Problem, dass eine getrennte Feder zugeführt und montiert werden muss, wodurch sich unabhängig von einem Problem der Handhabung eine ungünstige Kostensituation er- gibt. Des Weiteren muss das Stützelement leicht verschiebbar auf der Lenksäule angebracht sein, damit die Feder die Kraft über das Stützelement an den Innenring weiterleiten kann. Wegen steigender Qualitätsanforderungen ist daher diese Lösung nicht mehr akzeptabel. Aufgabe der Erfindung In steering column assembly, however, this poses the problem that a separate spring has to be fed and mounted, which results in an unfavorable cost situation regardless of a problem of handling. Furthermore, the support member must be easily slidably mounted on the steering column so that the spring can pass the force on the support member to the inner ring. Because of increasing quality requirements, this solution is therefore no longer acceptable. Object of the invention
Aufgabe der Erfindung ist es daher, eine Lagerung einer Welle in einem Gehäuse, insbesondere einer Lenksäule in einem Tragrohr eines Kraftfahrzeuges, so zu verbessern, dass die beschriebenen Nachteile vermieden werden. Insbesondere soll eine Lösung geschaffen werden, die kostengünstig ist, die Handhabung vereinfacht und eine sichere Krafteinwirkung auf das Schrägschulterlager gewährleistet. The object of the invention is therefore, a bearing of a shaft in a housing, in particular a steering column in a support tube of a motor vehicle, to be improved so that the disadvantages described are avoided. In particular, a solution is to be created that is inexpensive, simplifies handling and ensures a safe force on the angular contact bearing.
Zusammenfassung der Erfindung Summary of the invention
Erfindungsgemäß wird die Aufgabe der Erfindung dadurch gelöst, dass die Feder zumindest eine Federzunge aufweist, die einstückig am Innen- und/oder Außenring zumindest eines der Schrägkugellager angeformt ist. According to the invention the object of the invention is achieved in that the spring has at least one spring tongue, which is integrally formed on the inner and / or outer ring of at least one of the angular contact ball bearings.
In vorteilhafter Weise ist die Federzunge an einem Anschlagflansch des Außenringes und/oder an einem Stützflansch des Innenringes des Schrägkugellagers angebracht. Die Zunge kann in vorteilhafter Weise durch einen Stanzvorgang hergestellt werden, wobei ein Radialschnitt und ein Anschnitt in Umfangsrich- tung am Anschlagflansch oder Stützflansch angebracht werden und die dadurch von den Flanschen gelöste Zunge in axialer Richtung des Lagers verbogen wird. Zur besseren Abstützung des Lagerinnen- oder Lageraußenringes werden in vorteilhafter Weise mehrere, vorzugsweise drei Federzungen, über den Umfang verteilt angebracht. Die Federzungen an einem Anschlagflansch des Außenringes können sich direkt am Gehäuse bzw. am Tragrohr der Lenk- säulenlage- rung abstützen. In vorteilhafter Weise werden aber die Federzungen im Stütz- flansch des Innenringes angebracht, wobei die zumindest eine Federzunge sich an einem Ringwulst des Stützelementes abstützt und dadurch die Federkraft direkt auf den Innenring des Schrägkugellagers weiterleitet. Advantageously, the spring tongue is attached to a stop flange of the outer ring and / or on a support flange of the inner ring of the angular contact ball bearing. The tongue can advantageously be produced by a stamping process, wherein a radial cut and a gate are mounted circumferentially on the stop flange or support flange and the tongue thereby released from the flanges is bent in the axial direction of the bearing. For better support of the bearing inner or outer bearing ring several, preferably three spring tongues distributed over the circumference are advantageously mounted. The spring tongues on a stop flange of the outer ring can be supported directly on the housing or on the support tube of the steering column bearing. Advantageously, however, the spring tongues are mounted in the support flange of the inner ring, wherein the at least one spring tongue is supported on an annular bead of the support element and thereby passes the spring force directly to the inner ring of the angular contact ball bearing.
Die Halteelemente können in vorteilhafter Weise als innen geschlitzte Tellerfe- dern ausgebildet sein, die auf die Welle aufgeschoben werden, sich dann mit den gekippten Segmenten abstützen und die Stützelemente direkt axial fixieren. Dabei können die Stützelemente passgenau auf der Welle bzw. der Lenksäule angeordnet sein. Kurze Beschreibung der Zeichnungen The holding elements can be designed in an advantageous manner as internally slotted Tellerfe- countries, which are pushed onto the shaft, then supported with the tilted segments and fix the support elements directly axially. In this case, the support elements can be arranged accurately on the shaft or the steering column. Brief description of the drawings
