The invention relates to an electromagnetic actuator arrangement comprising an electromagnetic actuator device (), in particular a camshaft adjusting device, having a housing () and at least one armature unit which can be driven, in response to the energization of a stationary, axially aligned coil unit, in or parallel to the axial direction and which is designed to interact with at least one slide and/or tappet unit () extending in the axial direction, in particular a tappet unit () effecting a camshaft adjustment of an internal combustion engine, and at least one switching gate () which can be arranged on a slide cam () and through which a transverse central plane () passes, wherein the actuator device () comprises a detection device for contactless magnetic and/or electrical interaction with the switching gate (), which detection device comprises at least one magnetic field and/or electric field detection means which is designed to produce and/or detect a detection field acting directly on the switching gate (), and a detection field evaluation means () which is designed to determine the position of the switching gate () by means of the measured detection field, the magnetic field and/or electric field detection means being arranged at least partially outside the housing ().

Electromagnetic actuator arrangement

The invention relates to an electromagnetic actuating device () having at least two actuator units (a,b) which are arranged adjacently in a housing () and which each have electrically energizable static coil means (a,b), armature means (a,b) mounted so as to be movable relative to said coil means, and a plunger (a,b) which interacts with the armature means (a,b) and which is mounted so as to be movable along axial plunger direction (S, S) and which has a free end portion (a,) for engagement into an actuation partner, in particular a guide groove of a camshaft, wherein the plungers () of the actuator units () of the actuating device () are preferably arranged such that the plunger directions (S, S) thereof run parallel to one another, and wherein the device () has adjustment means () which are integrated in the housing () and which serve for varying the arrangement of at least one plunger along a plane (E) perpendicular to the respective plunger direction (S, S).

Electromagnetic actuating device with adaptable plunger arrangement

A device for adjusting a camshaft of an internal combustion engine includes a lifting profile assembly rotationally fixed on an axially movable camshaft, and has a control groove having a depth that varies along a rotation direction, an actuator to cause axial movement by controlled engaging in the control groove, and an electromagnetically drivable tappet unit that cooperates with the control groove such that, when rotating, a reset or driver effect is exerted on the tappet unit, wherein the tappet unit has at least two independently drivable tappets, the control groove engages a first individual tappet, forms a radially peripheral wall along a peripheral groove side whereby a second individual tappet is positioned outside the control groove during rotation, and a ramp section cooperating with the second individual tappet whereby the second individual tappet is reset or driven when the first individual tappet is reset or driven.

Device for adjusting a camshaft of an internal combustion engine

An electromagnetic actuating mechanism comprising an armature unit () which can be moved by a certain armature excursion along an axial direction of travel as a result of stationary coil means being energized, plunger means () which are associated with the armature unit, are designed such that the end thereof cooperates with an external actuating partner, and can be moved by a certain plunger excursion along the direction of travel from a starting position into an engagement position, and spring means () which bias the plunger means in the direction of travel.

Electromagnetic actuating mechanism

An electromagnetic actuating apparatus with two armature means which are designed to exert an actuating force on two tappet units which are extended in the longitudinal direction along a longitudinal movement axis and are guided such that they can be moved in a parallel manner in a common guide section of a housing which accommodates the armature means, wherein the tappet units each have an engagement end which is designed to interact with an actuating groove in a motor vehicle motor adjustment system and projects from the guide section at least in an engaged state, and the common guide section forms a guide end surface in which guide openings associated with the two tappet units, are open, wherein a connecting path which runs through center axes of the only two guide openings in the guide end surface forms an offset (v) from a surface center point of the guide end surface and/or from a surface center point of a housing end surface of the housing, wherein the surface center point lies on a perpendicular bisector of the connecting path.

Electromagnetic actuating apparatus and system for adjusting a functionality of a motor vehicle assembly

An electromagnetic actuator device having a core unit () having a coil means (), which core unit is constructed for interacting with armature means () that are movably guided relatively to the core unit, as a reaction to an energizing of the coil means, wherein the armature means have a plurality of tappet units (), which are spatially spaced from one another and can be driven simultaneously, to which tappet units, permanent magnet means () are assigned in the direction towards the core unit, which permanent magnet means have a permanent magnetization along a respective movement longitudinal axis of the tappet units, wherein the plurality of tappet units that can be driven parallel to one another magnetically interacts with an identically poled end face of the core unit and the permanent magnet means have an axially identically directed permanent magnetization.
