Abstract

Die Erfindung betrifft eine elektromagnetische Stellvorrichtung (1), die eine in axialer Richtung zwischen einer Ruheposition (I) und einer Stellposition (II) verschiebbare erste Ankeranordnung (10), welche mit einem ersten Stellelement (11) verbunden ist, einen in magnetische Wirkverbindung mit der ersten Ankeranordnung (10) bringbaren ersten Polkern (20),eine axial ausgerichtete bestrombare Spuleneinheit (50) zur Beeinflussung der magnetischen Wirkverbindung zwischen dem ersten Polkern (20) und der ersten Ankeranordnung (10) und eine mit einem zweiten Stellelement (31) verbundene, in axialer Richtung zwischen einer Ruheposition (I) und einer Stellposition (II) verschiebbare zweite Ankeranordnung (30) umfasst. Erfindungsgemäß ist ein in magnetische Wirkverbindung mit der zweiten Ankeranordnung (30) bringbarer zweiter Polkern (40) vorgesehen ist, welcher zur Beeinflussung von dessen magnetischen Wirkverbindung mit der zweiten Ankeranordnung (30) durch die Spuleneinheit (50) axial gegenüber dem ersten Polkern (10) ausgerichtet ist, sowie eine Permanentmagneteinheit (60), deren Magnetachse (61) zur Erzeugung einer magnetischen Wirkverbindung sowohl zwischen dem ersten Polkern (20) und der ersten Ankeranordnung (10) als auch zwischen dem zweiten Polkern (40) und der zweiten Ankeranordnung (30) radial ausgerichtet und feststehend ist.

The invention relates to an electromagnetic actuating device (1) which has a first armature arrangement (10) which can be displaced in the axial direction between a rest position (I) and an actuating position (II) and which is connected to a first actuating element (11) in magnetic operative connection with the first armature assembly (10) can be brought first pole core (20), an axially aligned energizable coil unit (50) for influencing the magnetic operative connection between the first pole core (20) and the first armature assembly (10) and a second actuator (31) connected , in the axial direction between a rest position (I) and a parking position (II) displaceable second armature assembly (30). According to the invention, a second pole core (40), which can be brought into magnetic operative connection with the second armature arrangement (30), is provided which axially influences the first pole core (10) through the coil unit (50) in order to influence its magnetic operative connection with the second armature arrangement (30). and a permanent magnet unit (60), the magnetic axis (61) of which generates a magnetic operative connection both between the first pole core (20) and the first armature arrangement (10) and between the second pole core (40) and the second armature arrangement (30 ) is radially aligned and fixed.
