Abstract
(DE)
Antriebseinrichtung (10), mit einer Antriebseinheit (12), welche eine Antriebswelle (14) aufweist, mit einem in einem Gehäuse (16) angeordneten Planetenradsatz (24), welcher ein Sonnenrad (34) aufweist, mit einer in axialer Richtung der Antriebswelle (14) verlaufende Relativbewegungen zwischen dem Sonnenrad (34) und der Antriebswelle (14) zulassenden Verbindungseinrichtung (46), über welche das Sonnenrad (34) von der Antriebswelle (14) antreibbar ist, und mit einem ein Wälzlager (50) aufweisendes Axiallager (48) zum axialen Lagern des Sonnenrads (34), wobei das Axiallager (48) in axialer Richtung zwischen der Antriebseinheit (12) und dem Planetenradsatz (24) angeordnet ist und aufweist: einen Lagertopf (56), an welchem das Wälzlager (50) über dessen drehfest mit dem Lagertopf (56) verbundenen Außenring (58) in axialer Richtung abgestützt ist; wobei der Lagertopf axial fest mit dem Gehäuse (16) verbunden.
(EN)
A drive device (10), having a drive unit (12) which has a drive shaft (14), having a planetary gear set (24) which is arranged in a housing (16) and which has a sun gear (34), having a connecting device (46) which permits relative movements, running in an axial direction of the drive shaft (14), between the sun gear (34) and the drive shaft (14) and via which the sun gear (34) can be driven by the drive shaft (14), and having an axial bearing (48) which has a rolling bearing (40) and which serves for axially bearing the sun gear (34), wherein the axial bearing (48) is arranged in an axial direction between the drive unit (12) and the planetary gear set (24) and has: a bearing pot structure (56) on which the rolling bearing (50) is supported in an axial direction by way of the outer ring (58) of said rolling bearing, which outer ring is connected to the bearing pot structure (56) for conjoint rotation; wherein the bearing pot structure is connected axially fixedly to the housing (16).
