Abstract
An electric setting drive for an automotive vehicle speed control or regulating system has an electric motor (1), a gearing (2) which is connected to said motor, and has an electromagnetic rapid-disconnect coupling as well as elements for converting a rotation of the gearing into a linear motion. The linear motion can be transmitted via a pull cable to a spring-loaded throttle valve. For the conversion of the rotary movement into linear movement there is provided a threaded spindle (3) which is turnably connected with the gearing (2) and engages into a thread of a displaceably mounted electrically energizable pot magnet (4). Facing the pot magnet (4) there is a linearly movable armature plate (6) to which the pull cable (7) is attached.
