Abstract

A drive device for a motor vehicle includes a drive unit with a driveshaft, a housing, and a planetary gear set disposed in the housing with a sun gear. A connection device allows relative movements, running in an axial direction of the driveshaft, between the sun gear and the driveshaft, via which the sun gear is drivable by the driveshaft. An axial bearing has a roller bearing for axially mounting the sun gear where the axial bearing is disposed in the axial direction between the drive unit and the planetary gear set. A bearing casing formed separately from the housing supports the roller bearing in the axial direction via an outer ring of the roller bearing non-rotationally connected to the bearing casing and the bearing casing is connected axially fixedly to the housing.
