The invention relates to an electric drive unit for a motor vehicle, having two electric drives (A,B), which are arranged in a housing casing () of a common drive housing () and each comprise a stator and a rotor () rotating together with a rotor shaft (A,B). Adjacent shaft ends (A,B) of the rotor shafts (A,B) are rotatingly mounted in a bearing housing (), which is the central region of a bearing plate () arranged in the drive housing (). In order to create an electrical drive unit having electric drives arranged one behind the other in a common drive housing, which is compact in the longitudinal direction, without disadvantages with respect to the strength of the drive housing being associated therewith, components of the bearing plate () are struts () which extend from the bearing housing () to the outside and connect the bearing housing () to the housing casing () of the drive housing ().

Electric drive unit for a motor vehicle

The invention relates to an electric drive unit for a motor vehicle, comprising an electric drive and a multi-stage transmission (), which is connected downstream of the electric drive and which is arranged, alone or together with the electric drive, in a drive housing (). The drive housing is composed of a housing shell (), the interior () of which annularly surrounds the transmission (), and an end wall (), which is formed integrally with the housing shell (). The end wall is provided, at the center thereof, with a transmission opening () for the transmission output shaft () of the transmission (). Cooling liquid is conducted through the drive housing in order to cool the components of the transmission. In order to improve the cooling performance while utilizing precisely the design-related particularities of the electric drive unit, a ring chamber () arranged around the transmission opening () is provided on the outside of the end wall (), and coolant channels () are formed in the drive housing (), which coolant channels lead from the interior () of the housing shell () into the ring chamber ().
