Abstract

A servo drive for activating a tailgate of a motor vehicle has a drive, a sun wheel driven by the drive and rotatably mounted on a first axle, and a planetary wheel rotatably mounted on a second axle. The sun wheel engages with the planetary wheel. The first and second axles have ends, are movably arranged at their ends facing away from the drive in a common web, and are spaced apart from one another by a constant distance. The planetary wheel engages in a ring gear segment which is fixedly connected to a bodywork, and an end of the web, which faces the ring gear segment, is movably connected to a connecting rod through a third axle. An end of the connecting rod facing away from the third axle is movably connected, via a fourth axle, to an output element which is connected by an end facing away from the fourth axle to the tailgate.
