ABSTRACT:
The invention starts from an actuating drive (10) with an electric motor (12), which drives an output shaft (32) via a toothed wheel gear (14) in a planetary design, which includes a first housing-mounted central wheel (16) and a second rotatable central wheel (18), whereby both central wheels (16, 18) each form gear steps with different step-down ratios with at least one planet wheel (20, 22) and the planet wheel (20) belonging to the first central wheel (16) is connected to the planet wheel (22) belonging to the second central wheel (18) in a torque-proof manner. It is proposed that the electric motor (12) drive a planet carrier (26) on which the planet wheels (20, 22) are pivoted.
