Abstract
The invention relates to a rotor shaft bearing arrangement comprising an electric motor-drivable rotor shaft (1) for a motor vehicle, such as a hybrid motor vehicle, further comprising a fixed bearing arrangement and a movable bearing arrangement, both of which include rolling elements (7). The movable bearing arrangement comprises a cylindrical roller bearing, the rolling elements (7) of which directly rest on a rotating surface (9) of the rotor shaft (1). The invention also relates to a drive unit comprising an electric motor, an internal combustion engine, and a rotor shaft (1) which can be driven by the electric motor and which is mounted by means of a rotor shaft bearing arrangement described above.
