ABSTRACT:
A method for driving a thrust body with a bidirectional linear solenoid drive having at least in each case one first actuator and one second actuator includes the steps of providing the at least one first actuator with at least one coil and a yoke and applying force alternately to the thrust body by interacting the first actuator with at least one armature ring. The armature ring is rotated with the second actuator to thereby axially shift the thrust body by the rotation of the armature ring. The thrust body is, then, shifted axially and is subsequently fixed in position with the thrust body being shifted in steps in this way until it has reached its respective final position. Also provided is a configuration for carrying out the method.
