摘要

The drive consists of an electric motor (2), a first planetary reduction gear stage (3), an output reduction gear stage (4) consisting of a spindle drive with a spindle (41) and threaded nut (42), a linear displacement element (5) and a housing (6). The spindle drive is self-locking and at least one element interacts with a jam protection device (43). A freely pivoting device (22) is arranged between the motor and the displacement element.
