Abstract
A drive unit with a planetary gear mechanism includes a stationary housing. A drive motor is eccentrically positioned on an end face of the stationary housing. A preliminary gear stage of the drive unit includes (i) an externally toothed spur gear shaft operatively connected to an output shaft of the drive motor, and (ii) an internally toothed gear that is operatively connected to the spur gear shaft, and that is coaxial with and is further operatively connected to a sun gear shaft. A hub housing is mounted on the stationary housing by at least two bearings, and has at least one integrated internal gear. At least two planetary stages are positioned downstream of the sun gear shaft, and are configured to transmit converted torque of the drive motor to the hub housing via the at least one integrated internal gear.
