摘要

The drive unit has an electric motor (6) and a coaxially mounted planetary gear (7) in a common housing (8) with internal teeth forming the ring gear teeth of the planetary gear. The electric motor has external teeth with which it is supported on the inner teeth of the common housing. The housing has a hollow cylindrical cross-section, whereby the outer dia. of the motor and planetary gear are essentially equal to the internal dia. of the housing.
