Patent ID: 7052428

Claim:
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 ) form gear steps with different step-down ratios with respective associated planet wheels ( 20 , 22 ) and the planet wheel ( 20 ) associated with the first central wheel ( 16 ) is connected to the planet wheel ( 22 ) associated with the second central wheel ( 18 ) in a torque-proof manner, characterized in that the electric motor ( 12 ) drives a planet carrier ( 26 ) on which the planet wheels ( 20 , 22 ) are pivoted, and that the two central wheels ( 16 , 18 ) are internal geared wheels, between which a wheel disk ( 40 ) of the planet carrier ( 26 ) is arranged, with a hub ( 36 ) positioned on the output shaft ( 32 ) and having a cylindrical jacket ( 38 ) on the outer circumference on which a rotor ( 30 ) of the electric motor ( 12 ) sits.
