BEARING ARRANGEMENT FOR A DRIVE DEVICE

摘要

The invention relates to a bearing arrangement for a drive device (1) comprising at least one electric machine (3) with a rotor (7). Said rotor (7) is mechanically connected to a power transmission unit (8). Said power transmission unit (8) is mechanically coupled to a differential (4) by means of a pinion shaft (5) introduced into a rotor shaft (7a) of the rotors (7) of at least one electric machine (3). Said rotor shaft (7a) is mounted by means of a first roller bearing (9) and a second roller bearing (14) and the pinion shaft (5a) is mounted by means of a third roller bearing (15) and a fourth roller bearing (16). A bearing cartridge (20) receives the second roller bearing (14), the third roller bearing (15) and the forth roller bearing (16), an external ring (27) of the second roller bearing (14) being supported on the bearing cartridge (20).
