Description

Die Erfindung betrifft eine elektromagnetische Nockenwellenverstelleinrichtung mit einer durch Bestromung einer stationären Spuleneinheit relativ zu einem Polkern bewegbaren und einen Ankerstößel aufweisenden Ankereinheit sowie mit einer Permanentmagneteinheit, durch welche die Ankereinheit im unbestromten Zustand der Spuleneinheit in einer Ruheposition gehalten ist.The invention relates to an electromagnetic camshaft adjusting device with a movable by energizing a stationary coil unit relative to a pole core and an anchor plunger armature unit and having a permanent magnet unit, by which the armature unit is held in the idle state of the coil unit in a rest position.

Eine solche elektromagnetische Nockenwellenverstelleinrichtung ist beispielsweise aus DE 20 2011 052 220 U1 bekannt. Die Permanentmagneteinheit weist dort einen scheibenförmigen Permanentmagneten auf, der zwischen einer ersten und einer zweiten magnetisch leitenden Polscheibe aufgenommen ist. Die beiden Polscheiben sind dabei mit dem Ankerstößel verschweißt. Das aus dem Gehäuse der elektromagnetischen Nockenwellenverstelleinrichtung herausragende Ende des Ankerstößels greift in eine umfangsseitige Nut einer auf einer Nockenwelle verstellbaren Nocke ein. Bei Bestromung der Spule der elektromagnetischen Nockenwellenverstelleinrichtung wird der Stößel in Richtung Nockenwelle geschoben und von der Nockenwelle beim Drehen wieder zurückgesetzt. Diese elektromagnetische Nockenwellenverstelleinrichtung verfügt über keine Federeinrichtung.Such an electromagnetic camshaft adjusting device is for example off DE 20 2011 052 220 U1 known. The permanent magnet unit has a disk-shaped permanent magnet there, which is accommodated between a first and a second magnetically conducting pole disk. The two pole discs are welded to the anchor tappet. The protruding from the housing of the electromagnetic camshaft adjusting device end of the anchor plunger engages in a circumferential groove of a cam shaft adjustable on a cam. When current is applied to the coil of the electromagnetic camshaft adjusting device, the plunger is pushed in the direction of the camshaft and reset by the camshaft when turning again. This electromagnetic camshaft adjusting device has no spring device.

Eine andere elektromagnetische Nockenwellenverstelleinrichtung beschreibt die EP 2 252 774 B1 , welche ebenfalls an der Stirnseite einer Nockenwelle eines Verbrennungsmotors platziert ist und als Reaktion auf eine Bestromung der stationären Spuleneinheit sowie durch das dadurch bewirkte Bewegen der Ankereinheit beziehungsweise des zugehörenden Ankerstößels eine Axialbewegung der Nockenwellenverstellung bewirkt. Die dortige Jocheinheit ist dabei relativ zur Spuleneinheit verdrehbar gelagert. Die Ankereinheit mit dem Ankerstößel ist dagegen in der drehbaren Joch- und Kerneinheit feststehend angeordnet. Damit kann insgesamt die Ankereinheit samt umgebender Jocheinheit mit der Nockenwelle rotieren.Another electromagnetic camshaft adjusting device describes the EP 2 252 774 B1 which is also placed on the end face of a camshaft of an internal combustion engine and causes axial movement of the camshaft adjustment in response to energization of the stationary coil unit and thereby caused by moving the armature unit or the associated armature tappet. The local yoke unit is rotatably mounted relative to the coil unit. The armature unit with the armature plunger, however, is arranged fixed in the rotatable yoke and core unit. Thus, in total, the armature unit, including the surrounding yoke unit, can rotate with the camshaft.

Schließlich beschreibt auch die EP 1 421 591 B1 eine elektromagnetische Nockenwellenverstelleinrichtung. Dort ist ebenfalls eine Permanentmagnetscheibe zwischen zwei Polscheiben vorgesehen, welche wiederum fest mit der Ankereinheit beziehungsweise dem Ankerstößel verbunden ist. Die Permanentmagneteinheit sorgt in Ruhestellung, das heißt bei nicht bestromter Spule, dafür, dass die Ankereinheit am Polkern festgehalten ist. Erst eine Strombeaufschlagung der Spule erzeugt ein Magnetfeld, welches dem Feld der Permanentmagnetscheiben entgegenwirkt und die Ankereinheit durch eine Federkraft unterstützt vom Polkern abgestoßen wird. Hierfür ist eine Spiralfeder vorgesehen, deren Federkraft kleiner dimensioniert ist als die Haltekraft der Permanentmagnetscheibe im unbestromten Zustand der Spuleneinheit. Sobald die Federkraft der Spiralfeder stärker ist als eine Anziehungs- beziehungsweise Rückhaltekraft der Permanentmagnetscheibe, kann eine Strombeaufschlagung der Spule entfallen und die Anordnung wird im ausgefahrenen Zustand des Ankerstößels gehalten, ohne dass es einer weiteren Stromzufuhr zur Spule bedarf.Finally, also describes the EP 1 421 591 B1 an electromagnetic camshaft adjusting device. There is also provided a permanent magnet between two pole discs, which in turn is firmly connected to the armature unit or the armature tappet. In the rest position, that is, when the coil is not energized, the permanent magnet unit ensures that the armature unit is held fast on the pole core. Only a current applied to the coil generates a magnetic field which counteracts the field of the permanent magnet discs and the armature unit is supported by a spring force repelled by the pole core. For this purpose, a coil spring is provided whose spring force is smaller than the holding force of the permanent magnet disc in the de-energized state of the coil unit. As soon as the spring force of the spiral spring is stronger than an attraction or retention force of the permanent magnet disc, a current loading of the coil can be omitted and the arrangement is kept in the extended state of the armature plunger, without the need for further power supply to the coil.

Die vorliegende Erfindung hat das Ziel, eine weitere elektromagnetische Nockenwellenverstelleinrichtung vorzuschlagen, die einfach herzustellen ist und trotzdem sehr schnelle Schaltzeiten, insbesondere Schaltzeiten von kleiner drei Millisekunden, erlaubt.The present invention aims to propose a further electromagnetic camshaft adjusting device, which is simple to manufacture and nevertheless allows very fast switching times, in particular switching times of less than three milliseconds.

Dieses Ziel wird durch eine elektromagnetische Nockenwellenverstelleinrichtung mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by an electromagnetic camshaft adjusting device having the features of patent claim 1.

Für die elektromagnetische Nockenwellenverstelleinrichtung nach der Erfindung ist dabei wesentlich, dass die Permanentmagneteinheit zwischen einem Gehäusedeckel und dem Polkern der elektromagnetischen Antriebseinheit feststehend angeordnet ist. Zusätzlich ist der Ankerstößel in einem Anker der Ankereinheit drehbar angeordnet, wobei sich die Federeinrichtung an einem Teil der Ankereinheit, welches drehfest oder annähernd drehfest angeordnet ist, abstützt. Der Teil der Ankereinheit ist der Anker, in dem der Ankerstößel drehbar sitzt.It is essential for the electromagnetic camshaft adjusting device according to the invention that the permanent magnet unit is arranged fixedly between a housing cover and the pole core of the electromagnetic drive unit. In addition, the armature plunger is rotatably arranged in an armature of the armature unit, wherein the spring device is supported on a part of the armature unit, which is arranged rotationally fixed or approximately rotationally fixed. The part of the anchor unit is the anchor in which the anchor tappet is rotatably seated.

Eine solche elektromagnetische Nockenwellenverstelleinrichtung zeichnet sich durch einen sehr kompakten Aufbau aus und durch sehr konstante Schaltzeiten, die unterhalb drei Millisekunden liegen können. Besonders vorteilhaft ist dabei die feststehende Anordnung des Permanentmagneten zwischen Gehäusedeckel und Polkern. Dies vereinfacht den Aufbau der elektromagnetischen Nockenwellenverstelleinrichtung, da der Permanentmagnet ohne irgendwelche Lager- oder Führungsbuchsen verbaut werden kann. In einer Weiterbildung der Erfindung ist die Ankereinheit als topfförmiger Anker ausgebildet, dessen Boden eine Öffnung aufweist, durch welche der Ankerstößel greift. Dabei ist der Ankerstößel im Anker drehbar angeordnet. Eine solche drehbare Anordnung des Ankerstößels im oder am Anker hat den Vorteil, dass der Anker selbst lediglich axial verschiebbar, jedoch drehfest, in der elektromagnetischen Nockenwellenverstelleinrichtung angeordnet werden kann.Such an electromagnetic camshaft adjusting device is characterized by a very compact design and by very constant switching times, which can be below three milliseconds. Particularly advantageous is the fixed arrangement of the permanent magnet between the housing cover and pole core. This simplifies the construction of the electromagnetic camshaft adjusting device, since the permanent magnet can be installed without any bearing or guide bushes. In one development of the invention, the anchor unit is designed as a cup-shaped anchor, the bottom of which has an opening through which the anchor plunger engages. In this case, the armature plunger is rotatably arranged in the armature. Such a rotatable arrangement of the armature tappet in or on the armature has the advantage that the armature itself only axially displaceable, but rotationally fixed, can be arranged in the electromagnetic camshaft adjusting.

Die Ankereinheit beziehungsweise der Anker kann dabei gemäß einer Weiterbildung der Erfindung in einer Führungsbuchse axial beweglich, jedoch verdrehfest, geführt sein. Eine solche Verdrehfestigkeit kann beispielsweise dadurch erreicht werden, dass die Führungsbuchse auf ihrer der Ankereinheit zugewandten Seite und die Ankereinheit auf ihrer der Führungsbuchse zugewandten Seite über eine Nut-Feder-Führung, die sich entlang der Mittenachse der elektromagnetischen Nockenwellenverstelleinrichtung erstreckt, verfügt.The anchor unit or the armature can be axially movable, but rotationally guided, according to an embodiment of the invention in a guide bush. Such a torsional strength can be achieved, for example, by virtue of the fact that the guide bushing has on its side facing the armature unit and the armature unit on its side facing the guide bushing a tongue and groove guide which extends along the center axis of the electromagnetic camshaft adjusting device.

Gemäß einer Weiterbildung der Erfindung ragt der Ankerstößel durch den Boden des topfförmig ausgebildeten Ankers und wird auf der Innenseite des Ankers am Boden von einer Haltescheibe umgriffen und dort festgelegt, vorzugsweise so, dass sich der Ankerstößel weiterhin in dem Anker und in der Öffnung der Haltescheibe verdrehen kann.According to one embodiment of the invention, the anchor plunger protrudes through the bottom of the cup-shaped anchor and is gripped on the inside of the anchor at the bottom of a retaining washer and fixed there, preferably so that the anchor plunger continue to rotate in the armature and in the opening of the retaining disc can.

Die erfindungsgemäß vorgesehene Federeinrichtung zur kraftmäßigen Unterstützung der Bewegung der Ankereinheit in Richtung Nockenwelle stützt sich mit ihrem einen Ende an einer geeigneten Fläche innerhalb der Nockenwellenverstelleinrichtung, beispielsweise am Gehäusedeckel, ab und mit ihrem entgegengesetzten, der Nockenwelle zugewandten Ende an der Ankereinheit. Vorzugsweise stützt sich dabei die Federeinrichtung mit einem Ende am Boden des topfförmig ausgebildeten Ankers ab. Dies hat den Vorteil, dass sich die Federeinrichtung an ihren beiden Enden an Flächen abstützt, die im Betrieb nicht oder fast nicht drehen, sodass auch kein Abrieb an den Abstützflächen der Federeinrichtung erfolgt. Deshalb ist in einer Weiterbildung der Erfindung vorgesehen, dass die oben erwähnte Haltescheibe einen kleineren Durchmesser aufweist als die vorzugsweise als Spiralfeder ausgebildete Federeinrichtung. Hierdurch kann sich das vordere Ende der Federeinrichtung am Boden des Ankers der Ankereinheit abstützen.The inventively provided spring means for supporting the force of the movement of the armature unit in the direction of the camshaft is supported at one end on a suitable surface within the camshaft adjusting, for example on the housing cover, and with its opposite, the camshaft end facing the anchor unit. Preferably, the spring device is supported with one end at the bottom of the cup-shaped anchor from. This has the advantage that the spring device is supported at its two ends on surfaces that do not or almost do not rotate during operation, so that no abrasion takes place on the support surfaces of the spring device. Therefore, it is provided in a development of the invention that the above-mentioned retaining disk has a smaller diameter than the spring device preferably designed as a helical spring. hereby For example, the front end of the spring device may be supported at the bottom of the anchor of the anchor unit.

Auf diesem Flansch 100 sitzt das Gehäuse 11 der elektromagnetischen Nockenwellenverstelleinrichtung 10 auf.The adapter element 14 passes through a flange 100. The housing 11 of the electromagnetic camshaft adjusting device 10 rests on this flange 100.

Im Inneren der elektromagnetischen Nockenwellenverstelleinrichtung 10 sitzt ein Polkern 30 beabstandet zur in das Innere der elektromagnetischen Nockenwellenverstelleinrichtung 10 zeigenden Fläche des Deckels 12. Dieser Polkern 30 ist zur Nockenwelle 80 hin gerichtet mit einer sich konisch verjüngenden Umfangsfläche ausgebildet zum Bereitstellen eines an sich bekannten Steuerkonus. Zwischen dem Polkern 30 und dem Deckel 12 ist eine Permanentmagneteinheit 60 in Form einer Permanentmagnetscheibe angeordnet. Dabei sind der Deckel 12, die Permanentmagneteinheit 60 und der Polkern 30 feststehend und zueinander vorzugsweise spaltfrei innerhalb des Gehäuses 11 platziert.Inside the electromagnetic camshaft adjusting device 10 sits a pole core 30 spaced from the inside of the electromagnetic camshaft adjusting device 10 facing surface of the lid 12. This pole core 30 is directed towards the camshaft 80 with a conically tapered peripheral surface formed to provide a known control cone. Between the pole core 30 and the cover 12, a permanent magnet unit 60 is arranged in the form of a permanent magnet disc. In this case, the cover 12, the permanent magnet unit 60 and the pole core 30 are fixed and placed within each other preferably without gaps within the housing 11.

Wie aus Figur 1 ersichtlich, sind sowohl der Polkern 30 als auch die Permanentmagnetscheibe 60 ringförmig gestaltet und weisen eine mittige Öffnung auf, durch welche eine Federeinrichtung 70, vorliegend eine Spiralfeder, greift. Die Spiralfeder 70 ist dabei zentrisch zur Mittenachse X ausgerichtet und stützt sich an ihrem in Figur 1 oben dargestellten Ende in einer ringförmigen Nut 12a des Deckels 12 ab. Mit ihrem gegenüberliegenden Ende stützt sich die Spiralfeder 70 am Boden 42 eines topfförmigen Ankers 41 ab. Vom Boden 42 des Ankers 41 erstreckt sich nach oben und die Spiralfeder 70 umgreifend eine umlaufende Wandung 43 des Ankers 41. Der Boden 42 des Ankers 41 verfügt über eine Öffnung 46, durch welche das obere Ende eines Ankerstößels 44 hindurchragt. Dieser Ankerstößel 44 bildet das zuvor erwähnte Stellelement für die Nockenwelle 80. Der Ankerstößel 44 ist an seinem durch den Boden 42 des Ankers 41 ragenden Ende von einer Haltescheibe 45 umgriffen und von dieser am Anker 41 festgelegt. Dieses Festlegen wird durch die Haltescheibe 45 dadurch erreicht, dass diese in eine umlaufende Nut am oberen Ende des Ankerstößels 44 ähnlich eines Sicherungsringes eingreift und am unteren Ende des Bodens 42 des Ankers 41 mit einem ringförmig hervorspringenden Flansch 44a des Ankerstößels 44 zusammenwirkt.How out FIG. 1 can be seen, both the pole core 30 and the permanent magnet disc 60 are annular and have a central opening through which a spring means 70, in this case a coil spring engages. The coil spring 70 is aligned centrally to the center axis X and relies on her in FIG. 1 End shown above in an annular groove 12 a of the lid 12 from. With its opposite end, the coil spring 70 is supported on the bottom 42 of a pot-shaped armature 41. From the bottom 42 of the armature 41 extends upward and the coil spring 70 encompassing a circumferential wall 43 of the armature 41. The bottom 42 of the armature 41 has an opening 46 through which the upper end of an anchor tappet 44 protrudes. This armature tappet 44 forms the aforementioned control element for the camshaft 80. The armature tappet 44 is gripped by a retaining disk 45 at its end protruding through the bottom 42 of the armature 41 and fixed by the latter to the armature 41. This fixing is achieved by the retaining washer 45 in that it engages in a circumferential groove at the upper end of the armature tappet 44 similar to a retaining ring and cooperates at the lower end of the bottom 42 of the armature 41 with a ring-shaped projecting flange 44a of the armature tappet 44.

Der Anker 41 mit seinem Boden 42 und der Wandung 43 bildet zusammen mit dem Ankerstößel 44 eine Ankereinheit 40. Die gesamte Ankereinheit 40, also der Anker 41 und der Ankerstößel 44, sind in Axialrichtung der Mittenachse X axial beweglich. Dies bedeutet, dass bei einer Axialbewegung des Ankers 41 der am Anker axial festgelegte Ankerstößel 44 mitbewegt wird. Hierfür sitzt der Anker 41 in einer Führungsbuchse 47, die es erlaubt, den Anker 41 axial zu bewegen. Allerdings ist der Anker 41 - anders als der Ankerstößel 44 - innerhalb dieser Führungsbuchse 47 nicht oder fast nicht verdrehbar angeordnet. Hierfür kann beispielsweise eine geeignete Nut-Feder-Verbindung vorgesehen werden. So kann die Führungsbuchse 47 beispielsweise eine entlang der Mittenachse X parallel verlaufende Längsnut aufweisen, in die ein entlang der Mittenachse X ebenfalls parallel verlaufender hervorspringender Längssteg an der umlaufenden Wandung 43 des Ankers 41 eingreift. Der besseren Übersichtlichkeit ist eine solche Nut-Feder-Verbindung zwischen Anker 41 und Führungsbuchse 47 in Figur 1 nicht dargestellt. In einer anderen Variante kann zwar grundsätzlich der Anker 41 in Bezug auf die Führungsbuchse 47 verdrehbar angeordnet sein. Durch die Federkraft der Federeinrichtung 70 wird der Anker 41 jedoch so axial verspannt, dass dieser nur entgegen der von der Federeinrichtung 70 aufgebrachten Federkraft verdreht werden kann. Bei entsprechend großer Dimensionierung der Federkraft ist der Anker 41 nahezu drehfest platziert. Im Vergleich hierzu kann jedoch der Ankerstößel 44 verhältnismäßig leichtgängig innerhalb des Ankers 41 verdreht werden. Im Ergebnis führt auch diese Lösung dazu, dass zwar der Ankerstößel 44 im Betrieb dreht, der Anker 41 jedoch nicht.The armature 41 with its bottom 42 and the wall 43, together with the armature tappet 44, forms an armature unit 40. The entire armature unit 40, that is to say the armature 41 and the armature tappet 44, are axially movable in the axial direction of the center axis X. This means that during an axial movement of the armature 41, the anchor tappet axially fixed on the armature is moved. For this purpose, the armature 41 is seated in a guide bush 47, which allows the armature 41 to move axially. However, the armature 41 - unlike the armature tappet 44 - within this guide bushing 47 is not arranged or almost non-rotatable. For this purpose, for example, a suitable tongue and groove connection can be provided. For example, the guide bushing 47 may have a longitudinal groove running parallel along the center axis X into which a protruding longitudinal ridge also extending parallel along the center axis X engages the peripheral wall 43 of the armature 41. The better clarity is such a tongue and groove connection between the armature 41 and guide bushing 47 in FIG. 1 not shown. In another variant, in principle, the armature 41 may be rotatably arranged with respect to the guide bushing 47. By the spring force of the spring device 70, the armature 41st However, so axially clamped that it can only be rotated against the force applied by the spring means 70 spring force. With a correspondingly large dimensioning of the spring force of the armature 41 is placed almost rotationally fixed. In comparison, however, the armature tappet 44 can be relatively easily rotated within the armature 41. As a result, this solution also causes the armature tappet 44 to rotate during operation, but the armature 41 does not.

Während also der Anker 41 zwar axial entlang der Mittenachse X verschiebbar, jedoch nicht verdrehbar, angeordnet ist, ist eine solche Verdrehung des Ankerstößels 44 erlaubt und auch ausdrücklich vorgesehen. Hierfür ist der Ankerstößel 44 in der Öffnung 46 im Boden 42 des Ankers 41 verdrehbar platziert. Eine solche verdrehbare Platzierung des Ankerstößels 44 kann beispielsweise dadurch erreicht werden, dass ein gewisses Spiel zwischen der Öffnung 46 des Ankers 41 und dem Ankerstößel 44 einerseits sowie zwischen dem Abstand der Haltescheibe 45 und dem Flansch 44a vorgesehen wird.Thus, while the armature 41, while axially displaceable along the center axis X, but not rotatable, is arranged, such a rotation of the armature tappet 44 is allowed and expressly provided. For this purpose, the armature plunger 44 is rotatably placed in the opening 46 in the bottom 42 of the armature 41. Such a rotatable placement of the armature tappet 44 can be achieved, for example, by providing a certain clearance between the opening 46 of the armature 41 and the armature tappet 44, on the one hand, and between the spacing of the retaining disk 45 and the flange 44a.

Der Vollständigkeit halber ist im Zusammenhang mit der Darstellung von Figur 1 noch ein flanschförmiges Jochteil 32 zu erwähnen, welches feststehend innerhalb des Gehäuses 11 der elektromagnetischen Nockenwellenverstelleinrichtung 10 platziert ist und das magnetische Gegenstück zum Polkern 30 darstellt. Der Polkern 30 und das Jochteil 32 sind vorzugsweise an einer weiteren Hülse 36 festgelegt, beispielsweise durch Verschweißen. Zusätzlich sind sowohl der Deckel 12 als auch das Jochteil 32 über Dichtungsringe 37, 38 gegenüber der Hülse 36 abgedichtet.For the sake of completeness, in connection with the presentation of FIG. 1 Still to mention a flange-shaped yoke 32, which is fixedly placed within the housing 11 of the electromagnetic camshaft adjusting device 10 and the magnetic counterpart to the pole core 30 represents. The pole core 30 and the yoke 32 are preferably fixed to a further sleeve 36, for example by welding. In addition, both the lid 12 and the yoke 32 are sealed by means of sealing rings 37, 38 relative to the sleeve 36.

Eine solche elektromagnetische Nockenwellenverstelleinrichtung 10, wie sie in Figur 1 dargestellt ist, arbeitet folgendermaßen. Dabei wird auch auf die Darstellungen der Figuren 2 und 3 Bezug genommen, die die elektromagnetische Nockenwellenverstelleinrichtung 10 in jeweils anderen, noch zu erläuternden Betriebszuständen zeigt. Die bekannten Bezugszeichen sind jedoch die gleichen.Such an electromagnetic camshaft adjusting device 10, as in FIG. 1 is shown works as follows. It is also on the representations of the FIGS. 2 and 3 Referring to the electromagnetic camshaft adjusting device 10 in each case, to be explained yet operating states. However, the known reference numerals are the same.

Figur 1 zeigt die elektromagnetische Nockenwellenverstelleinrichtung im Ruhezustand, d. h. bei nicht bestromter Erregerspule 22. Dabei ist angenommen, dass sich der Ankerstößel 44 zunächst in seiner obersten Stellung befindet. In diesem Zustand ist aufgrund der Permanentmagneteinheit 60 ein magnetischer Kraftfluss bereitgestellt, der die Ankereinheit 40 an den Polkern 30 herangezogen hält. Dabei ist wesentlich, dass die Federeinrichtung 70, also die vorgesehene Spiralfeder im Ausführungsbeispiel eine Federkraft hat, die kleiner dimensioniert ist als die Haltekraft der Permanentmagneteinheit 60 im unbestromten Zustand der Erregerspule 22. FIG. 1 shows the electromagnetic camshaft adjusting device at rest, ie when energized excitation coil 22. It is assumed that the armature tappet 44 is initially in its uppermost position. In this state, due to the permanent magnet unit 60, a magnetic flux of force is provided, which keeps the armature unit 40 applied to the pole core 30. It is essential that the spring device 70, so the proposed coil spring in the embodiment has a spring force which is smaller than the holding force of the permanent magnet unit 60 in the de-energized state of the exciter coil 22nd

Wird im nächsten Schritt die Erregerspule 22 von Strom durchflossen derart, dass die hierdurch bewirkte Kraft der Kraft der Permanentmagneteinheit 60 entgegen gerichtet ist, wird die Kraft der Permanentmagneteinheit 60 minimiert bzw. aufgehoben, so dass die Federkraft der Federeinrichtung 70 ausreicht, den Anker 41 am Ankerstößel 44 wegzudrücken. Bei entsprechender Bestromung der Erregerspule 22 kann dies so schnell geschehen, dass innerhalb von weniger als 3 msec ein Wegdrücken des Ankerstößels 44 möglich ist, um in die Nockenwellennut 82 der Nockenwelle 80 einzugreifen und diese entsprechend zu verstellen. Die Kraft der Permanentmagneteinheit 60 reicht in der in Figur 2 maximal ausgefahrenen Stellung des Ankerstößels 44 dann nicht mehr aus, um den Anker 41 zurückzuholen.If in the next step, the field coil 22 flows through current such that the force caused thereby the force of the permanent magnet unit 60 is directed, the force of the permanent magnet unit 60 is minimized or lifted, so that the spring force of the spring means 70 is sufficient, the armature 41 on Push away anchor tappet 44. With appropriate energization of the exciter coil 22, this can happen so quickly that within less than 3 msec a pushing away of the armature plunger 44 is possible to engage in the camshaft groove 82 of the camshaft 80 and adjust them accordingly. The force of the permanent magnet unit 60 extends in the in FIG. 2 then maximum extended position of the anchor tappet 44 then no longer to retrieve the armature 41.

Dieses Zurückholen wird erst dadurch möglich, dass die Nockenwellennut 82 der Nockenwelle 80 den Ankerstößel 44 wieder zurückdrückt, wie dies in Figur 3 dargestellt ist. Sobald der Anker 41 nahe genug an den Polkern 30 heranreicht, wird über den Permanentmagneten 60 der Kraftfluss so groß, dass der Anker in seine Ruhestellung weiter zurückgezogen wird bis dieser wieder seine Ruhestellung gemäß Figur 1 erreicht hat.This retrieval is only possible because the camshaft groove 82 of the camshaft 80, the anchor tappet 44 back again, as in FIG. 3 is shown. As soon as the armature 41 reaches close enough to the pole core 30, the force flux becomes so great over the permanent magnet 60 that the armature is further retracted into its rest position until it returns to its rest position FIG. 1 has reached.
