  • the invention relates to an electromagnetically operating Actuating device specified in the preamble of claim 1 Art.
  • the actuator is for electromagnetic control of the gas exchange valve one Reciprocating internal combustion engine provided.
  • the actuator has two spaced apart magnet systems, between which an anchor plate with an actuator stem to which the valve plate of the valve is coupled, can be moved back and forth.
  • the valve-side magnet system for opening the valve exists from a known electromagnet with excitation coil, while the magnetic system facing away from the valve for closing of the valve has a permanent magnet whose magnetic field can be neutralized by a compensation coil.
  • an electromagnetic one Control suggested. This consists of two magnet systems each with an excitation coil and an associated one Permanent magnets. Both systems, i.e. Permanent electromagnets, act on a common anchor plate between them, which is firmly connected to a valve stem. On the anchor plate and thus the valve press in opposite directions Towards two feathers. The permanent magnets hold the Anchor in the end positions. The holding force of the permanent magnets is used to trigger the valve movement by energizing the electromagnetic system canceled so that the Anchor and thus the valve under the action of the respective pre-stressed Springs and the attraction of each other Magnet is transferred to the other end position.
  • the holding force of the two permanent magnets can be determined by a direction opposite to the magnetic field of the permanent magnet Cancel the DC field of the associated electromagnet. Will the Excitation coil of the permanent electromagnet in question is supplied with a current of suitable polarity and strength the permanent magnet "neutralizes". The result is that the anchor falls under the action of the preloaded spring and from which other permanent electromagnet is captured. Whose Permanent magnet in turn holds the armature in its stroke end position until its holding force through the constant field of this permanent magnet associated electromagnetic system is canceled.
  • the advantage of this solution is that only a short one alternating energization of the electromagnetic systems necessary is. Another advantage is that with this Actuator relatively short valve closing and Opening times are available.
  • the Permanent magnets that the control valve in the normal case switched off motor and thus switched off power supply remains in the desired stroke end position.
  • actuators are also in DE 30 24 109 A1 and DE 33 07 683 C1 described. Both actuators have also two opposite electromagnetic systems, So two electromagnets, between which an anchor plate can be moved back and forth. The anchor plate itself is firmly connected with an employment. In these two However, documents is not a magnet system with permanent magnets intended.
  • the present invention is based on the object Electromechanical actuator mentioned at the beginning to train so that on the one hand a much simpler Control of the excitation coils is possible, and on the other hand the actuator in the de-energized state always in a defined, predetermined end position is brought.
  • This task is electromagnetic in the aforementioned Actuating device working in the license plate of the specified features solved.
  • the invention essentially consists in that the two excitation coils either in series or parallel to each other are switched.
  • the spring force of the springs and the magnetic force are preferred of the permanent magnet dimensioned so that the armature in de-energized state of the two excitation coils from the alone given by the springs stable spring position in the direction of the magnet system to which the permanent magnet is assigned, staggered.
  • the main advantage of the actuating device according to the invention lies in the fact that both excitation coils are from one and the same Control signals of a control circuit can be applied, so that a very simple control circuit is sufficient.
  • the control circuit can, for example, at its output terminals a pulse width modulated voltage signal for Provide the current with its duty cycle can be determined.
  • both magnet systems preferably with an overexcitation current switched (100% DE).
  • This overexcitation current neutralizes the permanent magnet and gives the other magnet system large switching forces.
  • the so-called Holding current reduced or switched back (lower% ED, lower power consumption, less heating).
  • the holding current is expediently dimensioned such that that the desired holding force between zero and an air gap Permanent magnet and magnet system is ensured.
  • Figure 1 is a sectional view through an embodiment an electromagnetic actuator shown.
  • the control device shown in sectional view has a tubular housing 1. Inside the case 1, a control shaft 15 is arranged centrally by two Plain bearings 19a, 19b is guided and with a still to be explained Compensating element 51 cooperates.
  • the staff 15 extends through the entire axial length of the housing 1.
  • a plate-shaped Anchor 17 attached to the stem 15.
  • the anchor 17 is located between two magnet systems and thus in the magnetic Circle of both the left and right magnet systems arranged. Both magnetic systems are after Kind of pot magnets preferably rotationally symmetrical.
  • the magnet system arranged on the left in FIG. 1 exists from a pot-shaped jacket 9, a core 5 and a coil former 7, on which an excitation coil 3 is wound.
  • Between the bottom plate of the jacket 9 and the core 5 is a plate-shaped permanent magnet 71 arranged.
  • the magnetization this permanent magnet 71 is chosen so that the north pole N and south pole S are provided as plate-shaped elements are, the plate levels parallel to the plane of the plate-shaped Permanent magnets 71 are arranged.
  • the separation of The north pole N and south pole S are dashed in Figure 1 in the permanent magnet 71 indicated.
  • the permanent magnet 71 also has a central opening in which an annular element 13 sits. At this Element 13 is supported by a compression spring 11 with one end. This compression spring 11 is arranged coaxially around the control shaft 15. Around this compression spring 11 is the core 5 of the Magnet system. The compression spring 11 is supported with her other End at the plate-shaped anchor 17.
  • This electromagnet has one a coil carrier 27 wound excitation coil 23.
  • the Magnetic system of this electromagnet is in this embodiment also designed rotationally symmetrical and has a one-piece magnetic body 25, which has a central through opening. Through this Through opening extends the stem 15.
  • the Position shaft 15 is guided in the bearing bush 19b, which on the Bottom side of the magnetic body 25 is attached.
  • Compression spring 21 which is on the one hand on the plate-shaped armature 17th and on the other hand on a ring-shaped projecting shoulder supports in the vicinity of the bearing bush 19b.
  • the left front this electromagnet is spaced from the opposite one Surface of the plate-shaped anchor 17.
  • the end of the actuator stem protruding from the bearing bush 19b 15 is connected to a compensating element 51.
  • This Compensating element 51 serves to ensure that even at existing end stop of the part to be moved the anchor plate 17 air gap on the magnetic body 25 of the electromagnet is present. This measure guarantees a low holding power.
  • the prestressed compression spring 53 in End of stroke position almost constant forces. So that to be moved Part that is articulated in the bore 52, too can perform an arcuate movement is the compensating element 51 on the control shaft 15 via a compensating ring 59 gimbal mounted.
  • Such actuators are ideal where Large actuating forces in the stroke start or stroke end position with a small one Construction volume, small weight and small performance required e.g. for flap adjustments in automotive applications. Of this actuator is also suitable for actuation of elements that require a specific work profile.
  • the two excitation coils 3, 23 are either connected in series or parallel to each other.
  • the row or Parallel connection of the two excitation coils 3, 23 is with output terminals 43, 44 of the control circuit 41 already mentioned in connection.
  • the entire actuator In the position of the armature 17 shown the entire actuator is in a de-energized state. In this de-energized state, the in the left magnet system ensures existing permanent magnet 71 for the armature 17 lies flat against the magnetic body 5, 9 of the left magnet system.
  • the main advantage of this control device is that very simple control option by switching on and off a control signal. A separate control of the two excitation coils 3, 23 is no longer necessary.
  • FIG. 3 shows two different block diagrams, in which the one in connection with FIG explained two excitation coils 3, 23 one after the other (cf. Figure 3 above) and on the other hand connected in parallel are (see FIG. 3 below).
