Definitions

  • Such an actuator is in the EP2528070 A2 described.
  • Such as in the DE 10 2006 015 233 B4 The actuating devices described by the applicant are adapted and optimized to the respective actuating task with regard to the housing, core, yoke and anchor geometry.
  • the actuating device described in the aforementioned publication is suitable for mass production and can be manufactured automatically due to the provision of a one-piece yoke core element, in contrast to the example in FIG DE 198 82 903 T1 or the DE 202 18 782 U1 described adjusting device in which separate core and yoke elements are provided.
  • the invention is therefore based on the object of specifying a large-volume electromagnetic actuating device which is characterized by good automatability, while at the same time minimizing installation space.
  • the electromagnetic adjusting device is to be designed as a pulling device, in which the armature then forming a tie rod is adjusted in the direction of the yoke core base when the coil device is energized.
  • the electromagnetic actuating device should also be usable in the context of an actuating system for applications in which the armature, in particular by the actuating partner, is subjected to a torque which tends to rotate the armature about its adjustment axis, in particular at high speed.
  • the armature can also be moved in different ways in one direction away from the yoke core bottom, for example by reversing the polarity of the current supply to the coil device and / or by spring force loading an optionally provided check spring and / or by a tensile force applied by the actuating partner.
  • the yoke core element in addition to a magnetic flux guiding function and a flux coupling function of the core section for coupling the magnetic flux into the armature, also has a carrier function or holding function for holding a guide pin for the armature, namely that which extends perpendicular to the adjustment axis and preferably at the same time a stop to limit the axial adjustment movement of the armature-forming yoke core has a, in particular central, guide pin recess, within which a guide pin is fixed, preferably by pressing, which during its axial adjustment movement, in particular over the entire maximum adjustment distance, into a corresponding, preferably centric Guide opening of the armature protrudes and extends parallel to the longitudinal extent of the sleeve-shaped yoke section.
  • this in particular on its inner circumference, more preferably on the inner circumference of the yoke section arranged axially adjacent to the core section, offers a support or holding surface for a slide bearing, which, for example, by pressing and / or Gluing and / or welding and / or is otherwise fixed to the yoke core element and which guides the armature on its outer circumference during its axial adjustment movement.
  • essential guide functions for the anchor which is preferably designed or controlled as a tie rod, are concentrated on the yoke core element, which is the direct carrier for a guide pin for guiding the anchor on its inner circumference and carrier for a slide bearing for guiding the anchor on its outer circumference.
  • the use of the one-piece yoke core element according to the invention results in a magnetic short circuit in the transition area between the core and the yoke, which in this transition area can preferably achieve magnetic saturation even at low coil currents, which has negative effects on efficiency and efficiency on the one-piece formation of the yoke and keep core within limits.
  • This effect can be further reduced by the fact that, according to a preferred development of the invention, the electromagnetic actuating device receives the effect of a proportional magnet working against a spring effect, so that short-circuit-related losses lie outside the operating core line in the force / stroke diagram of the device and therefore have no significant effect.
  • the core section and / or the yoke section taper / taper longitudinally in their thickness in the direction of the transition region and are set up such that a force-displacement characteristic of the adjusting device is linear over the stroke with constant coil current.
  • the guide pin recess in the yoke core base is designed as an axial through opening, in particular a through hole, which is more preferably closed at the end, ie on the axial side facing away from the armature, by the guide pin.
  • an axially adjustable, preferably elastomeric stop damping element can be supported in the axial direction, in particular on the bottom, in this closed opening or, in an alternative embodiment, on the bottom of a blind hole opening, with which the anchor is supported in a stop position adjusted in the direction of the core section, is supported in particular on the end face on the guide pin.
  • the guide opening in the armature is also designed as a through-opening, on the one hand because of a simpler manufacture and on the other hand for fixing a plunger or plunger section of the armature to a preferably sleeve-shaped guide section which has the guide opening and which is then on its side Outer circumference is guided on the plain bearing (plain bearing bush).
  • the yoke core element takes on additional functionality in addition to the two bearing functionalities and serves as a holder for an anti-rotation pin, which is arranged adjacent to a longitudinal central axis of the armature and which extends parallel to the guide pin into an anti-rotation pin recess.
  • This anti-rotation pin is fixed according to the invention (adjacent to the guide pin, preferably at a distance from it) in the yoke core base, in particular in an anti-rotation pin recess, it being particularly preferred to press the anti-rotation pin into it. wherein, in addition or as an alternative, welding and / or gluing can also be implemented.
  • the anti-rotation pin recess is particularly expedient to design the anti-rotation pin recess as a through hole which is closed at the end on the side facing away from the anchor by the anti-rotation pin.
  • the anti-rotation pin opening in the armature, into which the anti-rotation pin engages during the adjustment movement of the armature, in particular over its entire axial adjustment path, is also realized as a through opening for manufacturing reasons.
  • the further provision of an anti-rotation pin enables the use of the electromagnetic actuating device in the context of actuating systems in which the armature is subjected to a torque which tends to rotate the armature about its adjusting axis, which preferably coincides with its longitudinal central axis.
  • the absence of an anti-rotation device would lead to heavy loads and great wear on the actuating device.
  • the yoke core bottom forms an axial stop (end stop) for the armature.
  • the yoke core section can form a support surface for a stop damping element which, in a further development of the invention, can optionally be arranged in the interior space delimited by the yoke core element between the anchor end face and the yoke core base.
  • the yoke core bottom does not form an axial stop (end stop) for the armature, but this axial stop function is taken over by the guide pin in this alternative embodiment, which is then dimensioned in the axial direction so long that the armature immediately or preferably in an end stop position can be supported indirectly via a, preferably elastomeric, stop damping element on the guide pin.
  • This stop damping element is preferably adjustable back and forth together with the armature and is preferably fixed to the armature for this purpose. This can be achieved, for example, in that the stop damping element is pressed into the guide opening for receiving the guide pin.
  • the guide opening can be designed as a blind hole, it being advantageous if the stop damping element is supported axially on the bottom of the blind hole.
  • the stop damping element is preferably axially supported on an end face of the plunger section received in the through opening .
  • the guide opening is not designed as a blind hole, but rather as a through opening closed at the end by a plunger section in a multi-part anchor design, which will be explained later.
  • the stop damping element is preferably axially supported on an end face of the plunger section received in the through opening .
  • the guide opening is additionally or alternatively possible to support the stop damping element axially on an annular shoulder or similar supporting surface of the guide opening.
  • At least one stop damping element can be provided on the end face of the armature facing away from the guide pin recess in the yoke core bottom, preferably such a stop damping element on the armature is fixed, in particular pressed into an end opening, so that the armature can be supported via this stop damping element in an end stop position on the axial side facing away from the yoke core bottom, in particular on the housing side.
  • a stop damping element adjacent to the guide opening, in particular fixed to the armature, in order to support the armature in an end stop position on the yoke core bottom side via the stop damping element on the yoke core bottom.
  • a loose arrangement of a stop damping element between the anchor and a fixed component of the actuating device is also possible. It is also feasible to fix a stop damping element not to the anchor, but to a fixed component, in particular pressed into a component opening, in particular in the yoke core base.
  • the one-piece yoke core element is given additional functionality, namely in that it serves as a holder or axial securing device for an annular disk element which, in a development of the invention, is fixed in an inner circumferential groove of the yoke core element and which is penetrated by the armature .
  • the annular disk element can itself serve directly as an (immediate) end stop element axially opposite the yoke core base or alternatively as a carrier (immediate end stop element) for an optional damping element for damping the axial stop. It is particularly preferred if that Annular disk element in the aforementioned inner circumferential groove of the yoke core element is fixed by axial bracing, that is to say axially secured, which is realized in that the annular disk element can be elastically tensioned in the radial direction for insertion and then can be relaxed outward in the radial direction in order to radially into the inner circumferential groove of the yoke core element to snap inside radially outside.
  • the ring disk element in a further development of the invention is designed as a snap ring disk, namely from a material which preferably does not or poorly conducts the magnetic flux, very particularly preferably bronze.
  • the annular disk element can be accommodated in the annular groove in a relaxed manner or, alternatively, can be under a detent spring tension in the radial direction.
  • the armature in its, preferably plunger-shaped actuating section carries a roller bearing, preferably designed as a ball bearing (on which a component of the actuating partner is relative) to the non-rotatably arranged armature, preferably at high speeds, for example at more than 1000 rpm).
  • the armature in addition to a basically conceivable one-piece design of the armature, it is possible and preferred to form the armature in several parts, in which case it then preferably has a preferably sleeve-shaped guide section which has the guide opening, preferably in the form of a through-opening, on which a control section which has or adjusts the adjusting section forming, one-part or multi-part, preferably a smaller diameter than the guide section having plunger section, it being particularly expedient is when the plunger section is received in sections in the guide opening, for example by pressing.
  • the yoke core element and the coil device which at least partially encloses the yoke core element radially on the outside, are arranged in a common, flux-conducting housing, which is used for the return flow.
  • the housing is preferably connected on the side axially opposite the core section via a yoke disk to the yoke section of the yoke core element, the yoke disk preferably securing the yoke core element axially in the housing.
  • the storage of the armature can be further optimized according to a preferred embodiment of the invention, in which the armature is supported on the guide pin via a slide bearing, this (inner) slide bearing preferably being arranged in the guide opening of the armature, in particular being pressed into this.
  • This inner plain bearing is preferably axially spaced from the optional, but preferably provided, plain bearing (outer plain bearing) for guiding the armature on its outer circumference, this outer plain bearing preferably being, as mentioned, fixed, in particular pressed in, on the yoke core element, in particular on the inner circumference of the yoke core element .
  • the invention also leads to an actuating system comprising an electromagnetic actuating device designed according to the concept of the invention and an actuating partner which is preferably designed to introduce a torque about the adjusting axis into the armature, in particular via a roller bearing fixed to the armature.

In its axial end region, the latter carries a roller bearing 15, only partially shown, on which an actuating partner can roll around the adjusting axis V in the circumferential direction. In order to prevent a drag torque caused thereby from rotating the armature 2 in the circumferential direction about the adjustment axis V, an anti-rotation pin 16 to be explained later is provided.
