Description

Die Erfindung betrifft eine Lagerung einer Kraftfahrzeug-Getriebewelle nach dem Oberbegriff des Anspruchs 1.The invention relates to a bearing of a motor vehicle transmission shaft the preamble of claim 1.

Eine derartige Lagerung ist aus DE-AS 11 58 376 bekannt. Eine Getriebewelle ist im Gehäuse beidseits in Kegelrollenlagern gelagert. Bei Temperaturerhöhung verlängert sich das aus Aluminium gegossene Gehäuse stärker als die aus Stahl gefertigte Getriebewelle. Um diese unterschiedliche Wärmedehnung auszugleichen, ist der Außenring des einen Kegelrollenlagers gegenüber dem Gehäuse durch eine Lagerhülse befestigt, die an ihrem anderen Ende in das Gehäuse mit Schiebesitz eingepaßt ist.Such storage is known from DE-AS 11 58 376. A gear shaft is mounted on both sides in tapered roller bearings in the housing. At The temperature increase increases the aluminum cast housing stronger than the steel gear shaft. Around Compensating for different thermal expansion is the outer ring of one Tapered roller bearing attached to the housing by a bearing sleeve, the is fitted at its other end into the sliding seat housing.

Es ist die Aufgabe der Erfindung, eine Temperaturkompensation an einer anders gestalteten Lagerung einer Getriebewelle zu realisieren.It is the object of the invention to provide temperature compensation on a to realize a differently designed bearing of a gear shaft.

Zur Lösung dieser Aufgabe dienen die kennzeichnenden Merkmale des Anspruchs 1. Wenn ein Kompensationselement zwischen einem Festlager und einem Wellenabsatz der Getriebewelle eingespannt ist, kann durch geeignete Bemessung erreicht werden, daß das Kompensationselement die Getriebewelle um den gleichen Betrag in der einen Richtung zieht, um den das Getriebegehäuse in der anderen Richtung auswandert.The characteristic features of the claim serve to solve this problem 1. If a compensation element between a fixed bearing and a The shaft shoulder of the gear shaft is clamped by suitable Dimensioning achieved that the compensation element around the transmission shaft pulls the same amount in one direction around which the gear case emigrates in the other direction.

Nach Anspruch 2 wird eine solche Lagerung für eine Ritzelwelle verwendet, mit deren Kegelritzel ein Tellerrad der einen Fahrzeugachse angetrieben wird. Bei richtiger Auslegung des Kompensationselementes heben sich im Zahneingriff alle Wärmeverlagerungen auf und durch Temperaturerhöhung verursachte erhöhte Getriebegeräusche werden vermieden.According to claim 2, such a bearing is used for a pinion shaft, with their bevel pinion driven a ring gear of one vehicle axle becomes. With correct design of the compensation element stand out in Tooth meshing all heat transfer on and through temperature increase Increased gear noises caused are avoided.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend erläutert. An embodiment of the invention is shown in the drawing and is explained below.  

In einem aus einer Leichtmetall-Legierung gegossenen Achsgehäuse 1 eines sich in Fahrtrichtung X bewegenden Kraftfahrzeugs sind eine vom Geschwindigkeitswechselgetriebe angetriebene Ritzelwelle 2 und senkrecht zu ihr eine linke Achsantriebswelle 3 und eine rechte Achsantriebswelle 4 gelagert. Die Ritzelwelle 2 trägt endseitig ein Kegelritzel 5, das mit einem Tellerrad 6 im Eingriff steht. Das Tellerrad 6 ist an einem Ausgleichsgehäuse 7 angeflanscht. In ihm sind die zwischen den Achsantriebswellen 3, 4 der Vorderachse angeordneten Ausgleichskegelräder 8 gelagert.A pinion shaft 2 driven by the speed change gear and, perpendicular to it, a left axle drive shaft 3 and a right axle drive shaft 4 are mounted in an axle housing 1 cast from a light metal alloy of a motor vehicle moving in the direction of travel X. The pinion shaft 2 carries at the end a bevel pinion 5 which is in engagement with a ring gear 6 . The ring gear 6 is flanged to a differential housing 7 . The differential bevel gears 8 arranged between the axle drive shafts 3 , 4 of the front axle are mounted in it.

Die Ritzelwelle 2 ist nahe dem Kegelritzel 5 im Achsgehäuse 1 in einem Loslager 9, an ihrer anderen Seite in einem Festlager 10 des Achsgehäuses 1 gelagert. Als Loslager 9 dient ein Zylinderrollenlager, dessen Innenring 11 auf der Ritzelwelle 2 festsitzt. Der Innenring 11 liegt an einem Wellenabsatz 12 des Kegelritzels 5. Der Außenring 13 des Zylinderrollenlagers ist im Achsgehäuse 1 unverschieblich befestigt. Ihm gegenüber ist die Ritzelwelle 2 samt Innenring 11 längsverschieblich.The pinion shaft 2 is mounted near the bevel pinion 5 in the axle housing 1 in a floating bearing 9 , on its other side in a fixed bearing 10 of the axle housing 1 . A cylindrical roller bearing serves as the floating bearing 9 , the inner ring 11 of which is stuck on the pinion shaft 2 . The inner ring 11 lies on a shaft shoulder 12 of the bevel pinion 5 . The outer ring 13 of the cylindrical roller bearing is fixed immovably in the axle housing 1 . Opposite it, the pinion shaft 2 together with the inner ring 11 is longitudinally displaceable.

Um eine große Lagerbasis für die Ritzelwelle 2 zu schaffen, ist der Abstand des Festlagers 10 zum Loslager 9 verhältnismäßig groß gewählt. Als Festlager 10 wird ein Vierpunkt-Kugellager verwendet. Sein Außenring 14 ist im Achsgehäuse 1 befestigt. Die aneinander anliegenden beiden Innenringe 15, 16 des Festlagers 10 sind mit Übergangssitz so auf der Ritzelwelle 2 aufgepaßt, daß sie bei Einwirken hoher Axialkräfte sich gegenüber der Ritzelwelle längsverschieben lassen. Hierzu dient ein am Innenring 16 anliegendes Kompensationselement 17, das bei temperaturbedingter Längenänderung die Ritzelwelle 2 gegenüber dem Festlager 10 verschiebt.In order to create a large bearing base for the pinion shaft 2 , the distance between the fixed bearing 10 and the floating bearing 9 is chosen to be relatively large. A four-point ball bearing is used as the fixed bearing 10 . Its outer ring 14 is fastened in the axle housing 1 . The abutting two inner rings 15 , 16 of the fixed bearing 10 are fitted with a transition seat on the pinion shaft 2 so that they can be longitudinally displaced with respect to the pinion shaft when exposed to high axial forces. For this purpose, a compensation element 17 abuts against the inner ring 16 , which shifts the pinion shaft 2 relative to the fixed bearing 10 when the length changes due to temperature.

Das Kompensationselement 17 besteht aus einem mit einer Kunststoff-Dehnmasse 18 gefüllten Metalltopf 19, der mit seinem Boden am Innenring 16 anliegt. Die Kunststoff-Dehnmasse 18 besteht aus konditioniertem Polyamid oder FPM (Viton). Sie ist mit einer im Metalltopf 19 längsgeführten Metallscheibe 20 abgedeckt. Bei Wärmeausdehnung drückt die Kunststoff-Dehnmasse 18 über die Metallscheibe 20, eine Distanzhülse 21 und den Innenring 11 auf den Wellenabsatz 12 des Kegelritzels 12. Da sich das Kompensationselement 17 zugleich am Festlager 10 abstützt, verschiebt es die Ritzelwelle 2 ihm gegenüber. Durch geeignete Bemessung wird erreicht, daß die Längsverschiebung etwa so groß ist, wie die Differenz aus der Verlängerung des Achsgehäuses 1 abzüglich der Verlängerung der Ritzelwelle 2, die in Gegenrichtung erfolgt. Somit verbleibt das Zahnspiel an der Kegelritzel 5 - Tellerrad 6 - Verzahnung, das im kalten Zustand bei Montage durch Toleranzscheiben 22 eingestellt wird, bei Temperaturerhöhung annähernd konstant.The compensation element 17 consists of a metal pot 19 filled with a plastic expansion compound 18 , the bottom of which rests on the inner ring 16 . The plastic expansion compound 18 consists of conditioned polyamide or FPM (Viton). It is covered with a metal disk 20 which is longitudinally guided in the metal pot 19 . In the event of thermal expansion, the plastic expansion compound 18 presses onto the shaft shoulder 12 of the bevel pinion 12 via the metal disk 20 , a spacer sleeve 21 and the inner ring 11 . Since the compensation element 17 is also supported on the fixed bearing 10 , it shifts the pinion shaft 2 relative to it. Suitable dimensioning ensures that the longitudinal displacement is approximately as large as the difference between the extension of the axle housing 1 minus the extension of the pinion shaft 2 , which takes place in the opposite direction. Which is set in the cold state in assembly due to tolerance disks 22, approximately constant with increasing temperature toothing, - Thus, the backlash remains on the bevel pinion 5 - ring gear. 6

Der Längsverschiebung des Festlagers 10 zusammen mit dem Achsgehäuse 1 wirken zwei Tellerfedern 23 entgegen, die zwischen dem hinteren Innenring 15 des Festlagers 10 und einer Lager-Befestigungsmutter 24 eingespannt sind. Die Vorspannung wird so groß gewählt, daß im kalten Zustand die im Betrieb auftretende Zugkraft der Ritzelwelle von 12 KN abgedeckt ist. Bei Erwärmung wandert das Festlager 10 mit dem Achsgehäuse 1 nach hinten und die Tellerfedern 23 werden um einen entsprechenden Betrag weiter verspannt.The longitudinal displacement of the fixed bearing 10 together with the axle housing 1 are counteracted by two plate springs 23 which are clamped between the rear inner ring 15 of the fixed bearing 10 and a bearing fastening nut 24 . The preload is selected to be large enough that the tensile force of the pinion shaft occurring during operation is covered by 12 KN when cold. When heated, the fixed bearing 10 moves with the axle housing 1 to the rear and the plate springs 23 are further tensioned by a corresponding amount.
