Gebiet der ErfindungField of the invention
Die Erfindung betrifft einen elektromagnetischen Aktuator. Dieser umfasst ein Gehäuse mit einer elektrisch bestrombaren Magnetspuleneinrichtung, einen ersten Aktuatorstift und einen zweiten Aktuatorstift, die zwischen einer in das Gehäuse eingefahrenen Ruheposition und einer aus dem Gehäuse ausgefahrenen Arbeitsposition voneinander unabhängig verfahrbar im Gehäuse gelagert sind, sowie einen dem ersten Aktuatorstift zugeordneten ersten Permanentmagneten und einen dem zweiten Aktuatorstift zugeordneten zweiten Permanentmagneten, die mit den Aktuatorstiften und der Magnetspuleneinrichtung in kraftübertragender Wirkverbindung stehen.The The invention relates to an electromagnetic actuator. This includes a housing with an electrically energized solenoid device, a first actuator pin and a second actuator pin, the between a retracted into the housing rest position and a working position extended out of the housing moved independently of each other in the housing and a first permanent magnet associated with the first actuator pin and a second permanent magnet associated with the second actuator pin, the with the Aktuatorstiften and the solenoid device in force-transmitting Active compound stand.

als gattungsbildend betrachteten
Nachteilig an diesem Aktuator ist dessen hoher Herstellaufwand, da sich kostenwirksame Synergieeffekte im wesentlichen auf das gemeinsame Gehäuse beschränken.adversely this actuator is its high manufacturing costs, as cost-effective Synergy effects essentially on the common housing restrict.
In
der
Nachteilig
an dieser Ausgestaltung ist zum einen das mit dem erforderlichen
Abpralleffekt verbundene Funktionsrisiko des Aktuators dahingehend,
dass die Rückkehr des abprallenden Aktuatorstifts in dessen
magnetisch haftende Ruheposition unter allen Betriebsbedingungen
und über der gesamten Lebensdauer der Brennkraftmaschine
ohne weiteres nicht sicher reproduzierbar gewährleistet werden
kann. Zum anderen ist ein solcher Aktuator nicht für Verschiebenuten
mit gegensinnigem und sich kreuzendem Bahnverlauf geeignet, da in
diesem Fall beide Aktuatorstifte in die Verschiebenuten einspuren
und versuchen würden, dasselbe Nockenstück in
entgegengesetzte Richtungen zu verschieben. Die Nutgeometrie mit
sich kreuzendem Bahnverlauf ist beispielsweise aus der
Aufgabe der ErfindungObject of the invention
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Aktuator der eingangs genannten Art so fortzubilden, dass der Aktuator bei kompakter Bauweise mit möglichst geringem Aufwand herstellbar und für verschiedene Nutgeometrien verwendbar ist.Of the The present invention is therefore based on the object, an actuator of the type mentioned in such a way that the actuator in a compact Construction with the least possible effort produced and suitable for different groove geometries.
Zusammenfassung der ErfindungSummary of the invention
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruchs 1, während vorteilhafte Weiterbildungen und Ausgestaltungen den Unteransprüchen entnehmbar sind. Demnach wird die Aufgabe dadurch gelöst, dass die Magnetspuleneinrichtung bei elektrischer Umpolung ein sich mit der Bestromrichtung umkehrendes Magnetfeld erzeugt und einen den Permanentmagneten gemeinsam zugeordneten, stationären Kernbereich aufweist, an dem die Permanentmagnete bei unbestromter Magnetspuleneinrichtung magnetisch haften, wobei die Permanentmagnete zweipolig magnetisiert und in die Verfahrrichtung der Aktuatorstifte entgegengesetzt gepolt zueinander ausgerichtet sind.The Solution to this problem arises from the features of Claim 1, while advantageous developments and refinements the dependent claims are removable. Accordingly, the task becomes solved in that the magnetic coil device in electrical Umpolung a reversing with the Bestromrichtung magnetic field generated and assigned to the permanent magnet together, stationary core region, where the permanent magnets magnetically adhere to de-energized solenoid device, wherein the permanent magnets are magnetized bipolarly and in the direction of travel the Aktuatorstifte oppositely poled aligned with each other are.
Bei dieser Anordnung ist lediglich eine einzige, mit umgekehrten Polungen bestromte Magnetspule für zwei unabhängig voneinander verfahrbare Aktuatorstifte erforderlich. Die in Verfahrrichtung der Aktuatorstifte entgegengesetzte Ausrichtung der Permanentmagnetpole führt dazu, dass bei Bestromung der Magnetspule dasselbe Magnetfeld einen Permanentmagneten an den gemeinsamen Kernbereich anzieht und den anderen Permanentmagneten vom Kernbereich abstößt. Ausgehend vom unbestromten Ruhezustand des Akuators, bei welchem beide Permanentmagnete am Kernbereich haften und sich die Aktuatorstifte in deren eingefahrener Ruheposition befinden, führt also eine Bestromung der Magnetspule dazu, dass der erste Permanentmagnet in verstärktem Maße an den Kernbereich angezogen wird und der erste Aktuatorstift in seiner im Gehäuse eingefahrenen Ruheposition verharrt, während der zweite Permanentmagnet vom Kernbereich abgestoßen und gemeinsam mit dem damit ver bundenen zweiten Aktuatorstift in dessen ausgefahrene Arbeitsposition getrieben wird.at This arrangement is only a single, with reverse polarity energized solenoid for two independently movable actuator pins required. The in the direction of travel the Aktuatorstifte opposite orientation of the permanent magnet poles causes the same when the magnet coil is energized Magnetic field attracts a permanent magnet to the common core area and repels the other permanent magnet from the core area. Starting from the energized idle state of the Akuators, in which Both permanent magnets adhere to the core area and the actuator pins in their retracted rest position, so leads an energization of the solenoid to that of the first permanent magnet attracted to the core area to a greater extent and the first actuator pin retracted in its housing Resting position remains, while the second permanent magnet repelled from the core area and together with the so ver connected second actuator pin in its extended working position is driven.
Bei dazu entgegengesetzt gepolter Bestromung der Magnetspule kehrt sich die Wirkung des Magnetfelds um, so dass nunmehr der zweite Permanentmagnet verstärkt an den Kernbereich angezogen wird, während der erste Permanentmagnet abgestoßen wird. In analoger Weise verlagert sich nun der erste Aktuatorstift in dessen Arbeitsposition, während der zweite Aktuatorstift in seiner Ruheposition verharrt.at opposite poled energization of the solenoid reverses the effect of the magnetic field, so that now the second permanent magnet reinforced is attracted to the core area while the first permanent magnet is repelled. In analog Way, the first actuator pin now shifts into its working position, while the second actuator pin remains in its rest position.
In Weiterbildung der Erfindung sollen die einander zugeordneten Aktuatorstifte und Permanentmagnete aneinander befestigt und so im Gehäuse angeordnet sein, dass der Mittenabstand der Aktuatorstifte zueinander wesentlich kleiner als der Mittenabstand der Permanentmagnete zueinander ist. Diese exzentrische Anordnung der Aktuatorstifte gegenüber den jeweils zugehörigen Permanentmagneten ermöglicht es, die einander zugewandten magnetischen Wirkflächen der Permanentmagnete und des Kernbereichs im Hinblick auf die zu übertragenden Anziehungs- und Abstoßungskräfte ausreichend groß zu gestalten und gleichzeitig die Aktuatorstifte mit geringem Abstand zueinander anzuordnen.In Further development of the invention, the mutually associated actuator pins and permanent magnets attached to each other and arranged in the housing be that the center distance of the actuator pins to one another essential is smaller than the center distance of the permanent magnets to each other. This eccentric arrangement of Aktuatorstifte opposite allows the respective associated permanent magnet it, the mutually facing magnetic surfaces of the Permanent magnets and the core region with respect to the attraction and repulsive forces sufficiently large shape and at the same time the actuator pins with a small distance to arrange each other.
Ein
derart gestalteter Aktuator ist insbesondere für Verschiebenuten
geeignet, in die zwei Aktuatorstifte abwechselnd eingekoppelt werden.
Dies ist beispielsweise der Fall bei dreistufig variablen Ventiltrieben
gemäß der
In konstruktiv vorteilhafter Weise können die Permanentmagnete im wesentlichen als Flachquader ausgebildet sein, deren Kantenlänge in die Verfahrrichtung der Aktuatorstifte deutlich kleiner als orthogonal dazu ist. Gegenüber den bekannten Aktuatoren mit kreisförmigen Permanentmagneten bewirkt diese geometrische Ausgestaltung einen orthogonal zur Verfahrrichtung der Aktua torstifte deutlich kleineren Bauraumbedarf der Permanentmagnete bei konstanter magnetischer Wirkfläche und somit einen kompakter bauenden Aktuator. Zudem soll die den Permanentmagneten zugewandte Stirnfläche des Kernbereichs, entsprechend der Form beider Permanentmagnete, im wesentlichen rechteckig und im wesentlichen so groß wie die Summe der dem Kernbereich zugewandten Stirnflächen der Permanentmagnete sein.In constructively advantageous way, the permanent magnets be designed essentially as a flat cuboid whose edge length in the direction of movement of the Aktuatorstifte significantly smaller than orthogonal is to. Compared to the known actuators with circular Permanent magnets causes this geometric design a orthogonal to the direction of movement of Aktua pestles significantly smaller Space requirement of the permanent magnets with a constant magnetic effective area and thus a compact actuator. In addition, the permanent magnets should facing end face of the core region, according to the Shape of both permanent magnets, substantially rectangular and in essentially as big as the sum of the core area be facing end faces of the permanent magnets.
Im Hinblick auf einen insgesamt möglichst kompakt bauenden Aktuator soll das Gehäuse im Bereich der Permanentmagnete deren geometrischer Gestaltung als Flachquader folgen und somit einen im wesentlichen rechteckigen Querschnitt aufweisen. Dabei dient die Innenwandung des Gehäuses, in welcher die Permanentmagnete vorzugsweise mit geringem Spiel quer zur Verfahrrichtung der Aktuatorstifte beherbergt sind, als eine Verdrehung der Permanentmagnete begrenzender Anschlag.in the With regard to a total of compact as possible Actuator should be the housing in the area of the permanent magnets follow their geometric design as flat cuboid and thus have a substantially rectangular cross-section. there serves the inner wall of the housing, in which the permanent magnets preferably accommodated with little play transversely to the direction of movement of the actuator pins are, as a rotation of the permanent magnets limiting stop.
