Abstract
Description
Die Erfindung betrifft eine Getriebeeinheit für eine Achsantriebseinheit für ein Kraftfahrzeug mit einem Getriebegehäuse, in dem ein Differentialgetriebe mit einem Differentialkorb vorgesehen ist, das mit einer Antriebsachse drehbar wirkverbunden ist, wobei die Antriebsachse eine erste und eine zweite Seitenwelle aufweist, wobei die erste Seitenwelle einen getriebenahen Abtriebsflansch und die zweite Seitenwelle einen getriebefernen Abtriebsflansch aufweist. Des Weiteren betrifft die Erfindung eine Achsantriebseinheit mit einer derartigen Getriebeeinheit. The invention relates to a transmission unit for an axle drive unit for a motor vehicle having a transmission housing, in which a differential gear is provided with a differential carrier, which is rotatably operatively connected to a drive axle, wherein the drive axle has a first and a second side shaft, wherein the first side shaft a driven close Output flange and the second side shaft has a transmission remote output flange. Furthermore, the invention relates to an axle drive unit with such a transmission unit.
Derartige Getriebeeinheiten bzw. Achsantriebseinheiten sind aus dem Stand der Technik hinlänglich bekannt. So beschreibt beispielsweise die
Der Erfindung liegt daher die Aufgabe zugrunde, eine Getriebeeinheit bzw. eine Achsantriebseinheit bereitzustellen, deren Verschleißanfälligkeit hinsichtlich der Seitenwellen wesentlich geringer ausfällt als die bisherigen Lösungen. The invention is therefore based on the object to provide a gear unit or a final drive unit, the susceptibility to wear with respect to the side shafts turns out to be much lower than the previous solutions.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die erste Seitenwelle über ein erstes Wälzlager im Getriebegehäuse und über ein zweites Lager im Differentialkorb drehbar gelagert ist. Hierdurch konnte die Verschleißanfälligkeit der zweiten Seitenwelle auf einfache Weise wesentlich verringert werden. In einer besonders vorteilhaften Ausführungsform ist das zweite Lager als Nadellager ausgeführt, wodurch es möglich ist, auch in dem sehr begrenzt zur Verfügung stehenden Bauraum des Differentialgetriebes eine optimale Lagerung der zweiten Seitenwelle zu gewährleisten. Eine weitere Verringerung der Verschleißanfälligkeit kann dadurch erreicht werden, dass ein Axialgleitlager vorgesehen ist. This object is achieved in that the first side shaft is rotatably supported via a first rolling bearing in the gear housing and a second bearing in the differential carrier. As a result, the susceptibility to wear of the second side shaft could be significantly reduced in a simple manner. In a particularly advantageous embodiment, the second bearing is designed as a needle bearing, which makes it possible to ensure optimum storage of the second side shaft even in the very limited available space of the differential gear. A further reduction of the susceptibility to wear can be achieved by providing an axial sliding bearing.
Die Erfindung wird ebenfalls gelöst durch eine Achsantriebseinheit mit einer derartigen Getriebeeinheit, wobei das Getriebegehäuse Teil einer Gehäuseanordnung ist, in der eine Elektromaschine vorgesehen ist, wobei die zweite Seitenwelle an einer Lagerstelle der Gehäuseanordnung mittels eines Wälzlagers gelagert ist. Hierbei ist es insbesondere vorteilhaft, wenn die Lagerstelle für die zweite Seitenwelle in einem Lagerschild der Elektromaschine ausgebildet ist. The invention is also achieved by an axle drive unit having such a gear unit, wherein the gear housing is part of a housing arrangement in which an electric machine is provided, wherein the second side shaft is mounted at a bearing point of the housing assembly by means of a rolling bearing. It is particularly advantageous if the bearing for the second side shaft is formed in a bearing plate of the electric machine.
Die Erfindung wird nun anhand einer Zeichnung näher erläutert, hierbei zeigt:The invention will now be explained in more detail with reference to a drawing, in which:
Erfindungsgemäß ist nun vorgesehen, dass die erste Seitenwelle
In vorteilhafter Weise ist die beschriebene Getriebeeinheit
