Definitions
- the present invention relates to an electromagnetic actuator.
- the present invention relates to an electromagnetic adjusting device with at least two actuator units and adjusting means for changing the relative position of the plunger of the actuator units.
- Electromagnetic adjusting devices as actuators for a wide variety of adjusting tasks in the motor vehicle sector are sufficiently known from the prior art. As for example in DE 20 114 466 U1 shown, these generally have stationary coil means that can be energized, armature means that are movably mounted relative to them, and a ram that interacts with them and is movably mounted along an axial direction of the ram, which can be driven in response to energizing the coil means along the ram direction and can be moved out of the actuator housing.
- Such actuators are used in particular for adjusting the camshaft of an internal combustion engine.
- at least two actuators to be provided adjacent are generally required, in particular in order to be able to realize a wide variety of positioning of the camshaft by means of two adjacently arranged tappets of the actuators.
- Such an embodiment is generally manufactured specifically for an interaction with a specific, predefined actuating partner, for example a specific camshaft guide, and its possible application or use is therefore very limited.
- Corresponding actuator arrangements are off DE102016123571A1 , DE102017114246A1 , DE102013108027A1 and JP2017078338A famous.
- the present invention is based on the object of overcoming the above-mentioned disadvantages of the prior art or at least significantly reducing them.
- an improved electromagnetic actuating device is to be provided which enables optimized adaptability with regard to installation and fitting tolerances at the installation site, while at the same time having a space-saving design and low production costs.
- the invention in a first aspect, relates to an electromagnetic actuating device having at least two actuator units arranged adjacent to one another in a housing, each having stationary coil means that can be energized, armature means mounted so as to be movable relative to them, and a tappet which interacts with the anchoring means and is mounted so that it can move along an axial tappet direction, with a free end section for engaging in an actuating partner, in particular a guide groove of a camshaft, the tappets of the actuator units of the actuating device being arranged in such a way that their tappet directions run parallel to one another, and wherein the device has adjusting means integrated in the housing for changing the arrangement of at least one plunger along a plane perpendicular to the respective direction of the plunger.
- a plane perpendicular to the direction of the ram is understood to be a plane which is perpendicular to the respective axial direction of the ram and thus extends radially thereto.
- the adjusting means should allow the respective tappet arrangement to be adapted along or parallel to the said plane and thus be radially flexible.
- the device according to the invention achieves the effect that the plungers of the adjacent actuator units of the adjusting device can be variably positioned relative to one another, in contrast to the prior art, while at the same time maintaining the preferred axis-parallel alignment of the plungers or the plunger directions.
- the device is not only designed to be adaptable with regard to assembly or operating tolerances, but can also be used for different purposes or adapted with regard to an intervention in different adjusting partners.
- the present device can be adapted to differently designed guide grooves of camshafts.
- the integral design of the device results in simplified component handling and simplified assembly of the actuating device, for example possible in an internal combustion engine. Furthermore, increased vibration rigidity is achieved through the single-housing design.
- the arrangement or positioning of the respective tappet or the respective tappets of the device relative to one another, in particular with regard to their relative radial position, is preferably determined during assembly of the electromagnetic actuating device or in the installed state of the device.
- the arrangement of the rams is defined either by an associated actuator itself or by guide means positioned in front of it, for example a guide or mounting plate having predefined fitting bores.
- the adjusting means according to the invention for changing the arrangement of a tappet along a plane perpendicular to the associated tappet direction can also be used in an alternative electromagnetic actuating device which has only a single actuator unit.
- the respective plungers of the actuator units of the device can preferably be brought selectively at least into a retracted and an extended state along the respective axial direction of the plunger by interaction with the associated armature and coil means.
- the adjustment means are designed in such a way that they enable the relative arrangement of the tappets to be changed or adapted independently of a relative arrangement of the respectively associated armature means and/or coil means. This means that a change in the relative arrangement of the plunger of the device in a plane perpendicular to the direction of the plunger is preferably not accompanied by a change in the relative arrangement of the armature means and/or coil means, in particular not in a plane perpendicular to the direction of the plunger.
- the respective coil means of the individual actuator units are preferably arranged statically in the housing, i.e. their position in relation to one another and/or in relation to the housing cannot be changed.
- the respective anchor means of the individual actuator units are preferably arranged in an unchangeable manner relative to one another, at least in one direction perpendicular to the direction of the ram. This means that the armature means are arranged to be movable along their longitudinal axis with respect to the respective associated coil means, but a radial distance between the individual armature means of the device is preferably unchangeable and thus firmly defined.
- the respective anchoring means of the device can be variably arranged or mounted relative to one another in a direction perpendicular to the direction of the ram.
- the adjusting means are designed in such a way that they allow a change in an axial distance d between adjacent rams and/or a change in the preferably radial position of at least one respective ram relative to the respective other, in particular adjacent ram or to the housing of the device.
- the latter is understood to mean that in a top view or bottom view of the housing along the direction of the ram, a positioning of the respective ram that is preferably radial to the direction of the ram can be changed.
- this can be accompanied by or without changing the distance between the tappet axes.
- the adjusting means are preferably designed in such a way that they enable a change in the center distance d and/or the relative position of adjacent tappets to one another independently of a center distance and/or the relative position of the respective longitudinal axes of the respectively assigned coil means and/or the respectively assigned anchor means.
- the adjustment means are designed in such a way that they allow at least one ram to be moved relative to another ram in a direction perpendicular to the respective direction of the ram.

- a preferred axial spacing of the adjacently arranged rams of the device is between 10 and 30 mm, more preferably between 15 and 25 mm.
- the adjusting means preferably allow the respective ram position to be changed or shifted by up to 5 mm, more preferably by up to 10 mm and most preferably by up to 15 mm, in a direction perpendicular to the respective direction of the ram.

- the adaptable mounting can be, for example, a direct mounting of the ram or of a component connected to the ram, such as the ram guide described above, in which the ram can in turn be mounted in an axially displaceable manner.
- the adjustment means have at least one groove-shaped recess for the displaceable mounting of a tappet or a tappet guide receiving the tappet.
- the groove-shaped recess is preferably arranged in a base plate of the housing. This can be formed integrally with the housing or arranged on the housing as a separate component, for example in the form of a separate flange plate.

- the groove-shaped recess preferably has a homogeneous width.
- the adjusting means can have securing means, by means of which the respective ram and/or a ram guide accommodating the ram is secured against loss on the housing and in particular on the groove-shaped recess.
- the securing means can, for example, comprise a flange-like securing disk which is adapted to an outer diameter of the tappet guide and which can engage in the groove-shaped recess or is guided therein.
- Alternative security means can be realized by caulking the individual components to one another, so that the plunger or the guide receiving the plunger is secured to the housing.
- At least one ram whose position can be changed by the adjustment means is axially decoupled from the anchor means assigned to it and/or the coil means assigned to it.
- This means that the axial orientation of the plunger is not determined by the axial orientation of the associated stationary coil means and/or the axial orientation of the armature means.

- the invention relates to the use of the electromagnetic adjusting device as described above for mounting on an internal combustion engine of a motor vehicle for adjusting its camshaft.
- the camshaft itself or a component upstream of the camshaft can be used to determine the positioning of the tappets of the device in the installed state, for example a separate guide plate with predefined fitting bores, through which the tappets and/or the tappet guides are guided or supported in a radially fixed position relative to one another .

Description
Die vorliegende Erfindung betrifft eine elektromagnetische Stellvorrichtung. Insbesondere betrifft die vorliegende Erfindung eine elektromagnetische Stellvorrichtung mit wenigstens zwei Aktuatoreinheiten und Verstellmittel zur Veränderung der relativen Stößelpositionierung der Aktuatoreinheiten.The present invention relates to an electromagnetic actuator. In particular, the present invention relates to an electromagnetic adjusting device with at least two actuator units and adjusting means for changing the relative position of the plunger of the actuator units.
Elektromagnetische Stellvorrichtungen als Aktuatoren für verschiedenste Stellaufgaben im Kraftfahrzeugbereich sind aus dem Stand der Technik hinreichend bekannt. Wie beispielsweise in
Derartige Aktuatoren finden Verwendung insbesondere bei der Nockenwellenverstellung eines Verbrennungsmotors, wobei es sich zur Erreichung kurzer Schaltzeiten bei gleichzeitiger Möglichkeit zur wirtschaftlichen Serienproduktion als vorteilhaft erwiesen hat, derartige Aktuatoren ankerseitig mit Permanentmagneten zu versehen, welche abstoßend mit den bestromten Spulenmittel zusammenwirken. Gerade für die Verwendung zur Nockenwellenverstellung werden jedoch im Regelfall wenigstens zwei benachbart vorzusehende Aktuatoren benötigt, insbesondere um verschiedenste Positionierungen der Nockenwelle durch zwei benachbart angeordnete Stößel der Aktuatoren verwirklichen zu können.Such actuators are used in particular for adjusting the camshaft of an internal combustion engine. In order to achieve short switching times while at the same time enabling economical series production, it has proven advantageous to provide such actuators with permanent magnets on the armature side, which interact repulsively with the energized coil means. However, precisely for use in adjusting the camshaft, at least two actuators to be provided adjacent are generally required, in particular in order to be able to realize a wide variety of positioning of the camshaft by means of two adjacently arranged tappets of the actuators.
Aus dem Stand der Technik ist somit bereits bekannt, zwei separate Aktuatoren benachbart anzuordnen und zum Eingriff der Stößel in die Nockenwelle geeignet zu betreiben. Dies verursacht jedoch zusätzlichen Aufwand im elektrischen Anschluss und in der Montage der einzelnen Aktuatoren. Auch können relativ geringe Stößelabstände aufgrund einer notwendigen Mindestgehäusebreite, welche durch die radiale Erstreckung der darin gelagerten Spulenmittel bedingt ist, nicht erzielt werden. Ebenso ist bekannt, zwei benachbarte und einzeln ansteuerbare Stößel in einem gemeinsamen Gehäuse anzuordnen. Eine solche Anordnung ist jedoch im Hinblick auf an einem Kraftfahrzeug-Verbrennungsmotor unvermeidlichen Montage- bzw. Betriebstoleranzen problematisch, da durch die mehrfache Stößelführung in einem einzelnen Gehäuse kein Toleranzausgleich möglich ist. Des Weiteren ist eine derartige Ausführung in der Regel speziell für eine Interaktion mit einem bestimmten vordefinierten Stellpartner, beispielsweise einer bestimmten Nockenwellenführung, gefertigt und somit ist deren Einsatzmöglichkeit bzw. Verwendung sehr begrenzt. Entsprechende Aktuatoranordnungen sind aus
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die vorgenannten Nachteile des Standes der Technik zu überwinden oder zumindest deutlich abzuschwächen. Insbesondere soll eine verbesserte elektromagnetische Stellvorrichtung bereitgestellt werden, welche eine optimierte Adaptierbarkeit hinsichtlich Einbau- und Passtoleranzen am Einbauort bei gleichzeitig platzsparender Ausführung und geringem Fertigungsaufwand ermöglicht. Diese Aufgabe wird durch den Gegenstand der unabhängigen Ansprüche gelöst. Die Unteransprüche stellen vorteilhafte Weiterbildungen der vorliegenden Erfindung dar.The present invention is based on the object of overcoming the above-mentioned disadvantages of the prior art or at least significantly reducing them. In particular, an improved electromagnetic actuating device is to be provided which enables optimized adaptability with regard to installation and fitting tolerances at the installation site, while at the same time having a space-saving design and low production costs. This object is solved by the subject matter of the independent claims. The dependent claims represent advantageous developments of the present invention.
In einem ersten Aspekt betrifft die Erfindung eine elektromagnetische Stellvorrichtung aufweisend wenigstens zwei in einem Gehäuse benachbart angeordnete Aktuatoreinheiten jeweils aufweisend bestrombare stationäre Spulenmittel, zu diesen relativ bewegbar gelagerte Ankermittel, und einen mit den Ankermitteln zusammenwirkenden und entlang einer axialen Stößelrichtung bewegbar gelagerten Stößel mit einem freien Endabschnitt zum Eingriff in einen Stellpartner, insbesondere einer Führungsnut einer Nockenwelle, wobei die Stößel der Aktuatoreinheiten der Stellvorrichtung derart angeordnet sind, dass deren Stößelrichtungen parallel zueinander verlaufen, und wobei die Vorrichtung im Gehäuse integrierte Verstellmittel zur Veränderung der Anordnung wenigstens eines Stößels entlang einer Ebene senkrecht zur jeweiligen Stößelrichtung aufweist.In a first aspect, the invention relates to an electromagnetic actuating device having at least two actuator units arranged adjacent to one another in a housing, each having stationary coil means that can be energized, armature means mounted so as to be movable relative to them, and a tappet which interacts with the anchoring means and is mounted so that it can move along an axial tappet direction, with a free end section for engaging in an actuating partner, in particular a guide groove of a camshaft, the tappets of the actuator units of the actuating device being arranged in such a way that their tappet directions run parallel to one another, and wherein the device has adjusting means integrated in the housing for changing the arrangement of at least one plunger along a plane perpendicular to the respective direction of the plunger.
Hierunter wird insbesondere verstanden, dass eine Anordnung bzw. Positionierung des jeweiligen Stößels durch die Verstellmittel anpassbar bzw. adaptierbar ist. Als Ebene senkrecht zur Stößelrichtung wird eine Ebene verstanden, welche senkrecht zur jeweiligen axialen Stößelrichtung und somit in radialer Erstreckung dazu liegt. Die Verstellmittel sollen insbesondere eine Anpassung der jeweiligen Stößelanordnung entlang bzw. parallel zu der genannten Ebene und somit radial flexibel ermöglichen.This means in particular that an arrangement or positioning of the respective tappet can be adjusted or adapted by the adjusting means. A plane perpendicular to the direction of the ram is understood to be a plane which is perpendicular to the respective axial direction of the ram and thus extends radially thereto. In particular, the adjusting means should allow the respective tappet arrangement to be adapted along or parallel to the said plane and thus be radially flexible.
Durch die erfindungsgemäße Vorrichtung wird erzielt, dass die Stößel der benachbarten Aktuatoreinheiten der Stellvorrichtung entgegen dem Stand der Technik relativ zueinander variabel positionierbar sind, bei gleichzeitiger Beibehaltung der vorzugsweisen achsparallelen Ausrichtung der Stößel bzw. der Stößelrichtungen. Hierdurch ist die Vorrichtung nicht nur hinsichtlich Montage- bzw. Betriebstoleranzen adaptierbar ausgebildet, sondern auch für unterschiedliche Einsatzzwecke einsetzbar bzw. hinsichtlich eines Eingriffs in unterschiedliche Stellpartner anpassbar. Insbesondere kann die vorliegende Vorrichtung an unterschiedlich ausgebildete Führungsnuten von Nockenwellen angepasst werden. Gleichzeitig wird durch die eingehäusige Ausbildung der Vorrichtung ein vereinfachtes Bauteilhandling und eine vereinfachte Montage der Stellvorrichtung beispielsweise in einem Verbrennungsmotor ermöglicht. Des Weiteren wird durch die eingehäusige Ausbildung eine erhöhte Vibrationssteifigkeit erzielt.The device according to the invention achieves the effect that the plungers of the adjacent actuator units of the adjusting device can be variably positioned relative to one another, in contrast to the prior art, while at the same time maintaining the preferred axis-parallel alignment of the plungers or the plunger directions. As a result, the device is not only designed to be adaptable with regard to assembly or operating tolerances, but can also be used for different purposes or adapted with regard to an intervention in different adjusting partners. In particular, the present device can be adapted to differently designed guide grooves of camshafts. At the same time, the integral design of the device results in simplified component handling and simplified assembly of the actuating device, for example possible in an internal combustion engine. Furthermore, increased vibration rigidity is achieved through the single-housing design.
Eine Festlegung der Anordnung bzw. Positionierung des jeweiligen Stößels bzw. der jeweiligen Stößel der Vorrichtung zueinander, insbesondere hinsichtlich derer relativer radialer Position, erfolgt vorzugsweise bei der Montage der elektromagnetischen Stellvorrichtung bzw. im verbauten Zustand der Vorrichtung. Hierbei wird die Anordnung der Stößel entweder durch einen zugehörigen Stellpartner selbst oder durch diesem vorgelagerte Führungsmittel, beispielsweise eine vordefinierte Passbohrungen aufweisende Führungs- oder Montageplatte, festgelegt.The arrangement or positioning of the respective tappet or the respective tappets of the device relative to one another, in particular with regard to their relative radial position, is preferably determined during assembly of the electromagnetic actuating device or in the installed state of the device. In this case, the arrangement of the rams is defined either by an associated actuator itself or by guide means positioned in front of it, for example a guide or mounting plate having predefined fitting bores.
Die erfindungsgemäßen Verstellmittel zur Veränderung der Anordnung eines Stößels entlang einer Ebene senkrecht zur zugehörigen Stößelrichtung können auch bei einer alternativen elektromagnetischen Stellvorrichtung Anwendung finden, welche lediglich eine einzelne Aktuatoreinheit aufweist.The adjusting means according to the invention for changing the arrangement of a tappet along a plane perpendicular to the associated tappet direction can also be used in an alternative electromagnetic actuating device which has only a single actuator unit.
Die jeweiligen Stößel der Aktuatoreinheiten der Vorrichtung können vorzugsweise entlang der jeweils axialen Stößelrichtung durch Zusammenwirkung mit den zugeordneten Anker- und Spulenmitteln selektiv wenigstens in einen eingefahrenen und einen ausgefahrenen Zustand gebracht werden. In einer bevorzugten Ausführungsform sind die Verstellmittel derart ausgebildet, dass diese eine Veränderung bzw. Anpassung der relativen Anordnung der Stößel unabhängig von einer relativen Anordnung der jeweils zugehörigen Ankermittel und/oder Spulenmittel ermöglichen. Dies bedeutet, dass mit einer Veränderung der relativen Stößelanordnung der Vorrichtung in einer Ebene senkrecht zur Stößelrichtung vorzugsweise keine Veränderung der relativen Anordnung der Ankermittel und/oder Spulemittel einhergeht, insbesondere nicht in einer Ebene senkrecht zur Stößelrichtung.The respective plungers of the actuator units of the device can preferably be brought selectively at least into a retracted and an extended state along the respective axial direction of the plunger by interaction with the associated armature and coil means. In a preferred embodiment, the adjustment means are designed in such a way that they enable the relative arrangement of the tappets to be changed or adapted independently of a relative arrangement of the respectively associated armature means and/or coil means. This means that a change in the relative arrangement of the plunger of the device in a plane perpendicular to the direction of the plunger is preferably not accompanied by a change in the relative arrangement of the armature means and/or coil means, in particular not in a plane perpendicular to the direction of the plunger.
Die jeweiligen Spulenmittel der einzelnen Aktuatoreinheiten sind vorzugsweise im Gehäuse statisch, d.h. in ihrer Lage zueinander und/oder zum Gehäuse unveränderbar angeordnet. Die jeweiligen Ankermittel der einzelnen Aktuatoreinheiten sind vorzugsweise relativ zueinander wenigstens in einer Richtung senkrecht zur Stößelrichtung unveränderbar angeordnet. Dies bedeutet, dass die Ankermittel bezüglich der jeweiligen zugeordneten Spulenmittel zwar entlang ihrer Längsachse bewegbar angeordnet sind, eine radiale Distanz der einzelnen Ankermittel der Vorrichtung zueinander aber vorzugsweise unveränderbar und somit fest definiert ist. In einer alternativen Ausführungsform können die jeweiligen Ankermittel der Vorrichtung zueinander in einer Richtung senkrecht zur Stößelrichtung variabel angeordnet bzw. gelagert sein.The respective coil means of the individual actuator units are preferably arranged statically in the housing, i.e. their position in relation to one another and/or in relation to the housing cannot be changed. The respective anchor means of the individual actuator units are preferably arranged in an unchangeable manner relative to one another, at least in one direction perpendicular to the direction of the ram. This means that the armature means are arranged to be movable along their longitudinal axis with respect to the respective associated coil means, but a radial distance between the individual armature means of the device is preferably unchangeable and thus firmly defined. In an alternative embodiment, the respective anchoring means of the device can be variably arranged or mounted relative to one another in a direction perpendicular to the direction of the ram.
In einer bevorzugten Ausführungsform sind die Verstellmittel derart ausgebildet, dass diese eine Veränderung eines Achsabstands d benachbarter Stößel zueinander und/oder eine Veränderung der vorzugsweise radialen Position wenigstens eines jeweiligen Stößels relativ zum jeweiligen anderen, insbesondere benachbarten Stößel bzw. zum Gehäuse der Vorrichtung ermöglichen. Unter letzterem wird verstanden, dass in Draufsicht oder Untersicht auf das Gehäuse entlang der Stößelrichtung eine zur Stößelrichtung vorzugsweise radiale Positionierung des jeweiligen Stößels veränderbar ist. Dies kann je nach Ausführung der Verstellmittel mit oder ohne Veränderung des Stößelachsabstands einhergehen.In a preferred embodiment, the adjusting means are designed in such a way that they allow a change in an axial distance d between adjacent rams and/or a change in the preferably radial position of at least one respective ram relative to the respective other, in particular adjacent ram or to the housing of the device. The latter is understood to mean that in a top view or bottom view of the housing along the direction of the ram, a positioning of the respective ram that is preferably radial to the direction of the ram can be changed. Depending on the design of the adjusting means, this can be accompanied by or without changing the distance between the tappet axes.
Die Verstellmittel sind vorzugsweise derart ausgebildet, dass diese eine Veränderung des Achsabstands d und/oder der relativen Position benachbarter Stößel zueinander unabhängig von einem Achsabstand und/oder der relativen Position jeweiliger Längsachsen der jeweils zugeordneten Spulenmittel und/oder der jeweils zugeordneten Ankermittel ermöglichen.The adjusting means are preferably designed in such a way that they enable a change in the center distance d and/or the relative position of adjacent tappets to one another independently of a center distance and/or the relative position of the respective longitudinal axes of the respectively assigned coil means and/or the respectively assigned anchor means.
In einer bevorzugten Ausführungsform sind die Verstellmittel derart ausgebildet, dass diese eine Bewegung wenigstens eines Stößels gegenüber einem anderen Stößel in eine Richtung senkrecht zur jeweiligen Stößelrichtung ermöglichen. In einer weiter bevorzugten Ausführungsform ermöglichen die Verstellmittel eine relative Bewegung von beiden bzw. mehreren Stößel der Vorrichtung zueinander. Die einzelnen Stößel können dabei durch die Verstellmittel in gleicher Weise und/oder in unterschiedlicher Weise zueinander bewegbar angeordnet sein.In a preferred embodiment, the adjustment means are designed in such a way that they allow at least one ram to be moved relative to another ram in a direction perpendicular to the respective direction of the ram. In a further preferred embodiment, the adjustment means enable a relative movement of both or more plungers of the device to one another. The individual tappets can be arranged such that they can be moved in relation to one another in the same way and/or in different ways by the adjusting means.
Ein bevorzugter Achsabstand der benachbart angeordneten Stößel der Vorrichtung liegt zwischen 10 bis 30 mm, mehr bevorzugt zwischen 15 und 25 mm. Die Verstellmittel ermöglichen vorzugsweise eine Veränderung bzw. Verschiebung der jeweiligen Stößelposition um bis zu 5 mm, mehr bevorzugt um bis zu 10 mm und am bevorzugtesten um bis zu 15 mm, in eine Richtung senkrecht zur jeweiligen Stößelrichtung. Hierdurch wird eine besonders flexible Anpassbarkeit an unterschiedliche Einsatzzwecke und Stellpartner ermöglicht. Für den Anwendungsfall eines reinen Toleranzausgleichs ermöglichen die Verstellmittel vorzugsweise eine Veränderung bzw. Verschiebung der jeweiligen Stößelposition um bis zu 0,15 mm, vorzugsweise um bis zu 0,3 mm, und am bevorzugtesten um bis zu 0,5 mm, in eine Richtung senkrecht zur jeweiligen Stößelrichtung.A preferred axial spacing of the adjacently arranged rams of the device is between 10 and 30 mm, more preferably between 15 and 25 mm. The adjusting means preferably allow the respective ram position to be changed or shifted by up to 5 mm, more preferably by up to 10 mm and most preferably by up to 15 mm, in a direction perpendicular to the respective direction of the ram. This enables a particularly flexible adaptability to different purposes and partners. For the application of pure tolerance compensation, the adjusting means preferably allow a change or displacement of the respective ram position by up to 0.15 mm, preferably by up to 0.3 mm, and most preferably by up to 0.5 mm, in a vertical direction to the respective ram direction.
In einer bevorzugten Ausführungsform ist der jeweilige Stößel der Aktuatoreinheit mittels einer vorgesehenen Stößelführung im Gehäuse gelagert. Die Stößelführung ist vorzugsweise ein im Wesentlichen zylinderförmiges Bauteil, in welchem der Stößel in der jeweiligen Stößelrichtung axial verschiebbar gelagert bzw. geführt ist. Die Führung ist vorzugsweise in axialer Stößelrichtung unbeweglich am Gehäuse angeordnet und kann wenigstens teilweise aus einem Gehäusegrundkörper ragen. Die Führung kann beispielsweise zwei innenliegende Lagerpunkte zur Lagerung bzw. Führung des Stößels aufweisen. Alternativ kann der Stößel auch lediglich in einer zylindrischen Bohrung der Führung gelagert bzw. geführt sein.In a preferred embodiment, the respective plunger of the actuator unit is mounted in the housing by means of a plunger guide provided. The ram guide is preferably an essentially cylindrical component in which the ram is mounted or guided so that it can be displaced axially in the respective direction of the ram. The guide is preferably arranged immovably on the housing in the axial direction of the ram and can protrude at least partially from a housing base body. For example, the guide can have two internal bearing points for storage or Have leadership of the plunger. Alternatively, the plunger can also be mounted or guided only in a cylindrical bore of the guide.
In einer bevorzugten Ausführungsform weisen die Verstellmittel eine adaptierbare bzw. verstellbare Lagerung wenigstens eines Stößels einer Aktuatoreinheit im Gehäuse der Vorrichtung auf. Die adaptierbare Lagerung kann beispielsweise eine direkte Lagerung des Stößels sein oder eines mit dem Stößel verbundenen Bauteils, wie beispielsweise der oben beschriebenen Stößelführung, in welcher der Stößel wiederum axial verschiebbar gelagert sein kann.In a preferred embodiment, the adjustment means have an adaptable or adjustable mounting of at least one plunger of an actuator unit in the housing of the device. The adaptable mounting can be, for example, a direct mounting of the ram or of a component connected to the ram, such as the ram guide described above, in which the ram can in turn be mounted in an axially displaceable manner.
In einer bevorzugten Ausführungsform weisen die Verstellmittel wenigstens eine nutförmige Ausnehmung auf, zur verschiebbaren Lagerung eines Stößels oder einer den Stößel aufnehmenden Stößelführung. Die nutförmige Ausnehmung ist vorzugsweise in einer Bodenplatte des Gehäuses angeordnet. Diese kann integral mit dem Gehäuse ausgebildet sein oder als separates Bauteil, beispielsweise in der Form einer separaten Flanschplatte, an dem Gehäuse angeordnet sein. Die nutförmige Ausnehmung kann dabei wenigstens teilweise linear und/oder gebogen sein. In einer weiteren bevorzugten Ausführungsform kann die nutförmige Ausnehmung auch kreisabschnittsförmig ausgebildet sein und/oder eine komplexe Kurvenbahn formen. Die nutförmige Ausnehmung weist vorzugsweise eine homogene Breite auf.In a preferred embodiment, the adjustment means have at least one groove-shaped recess for the displaceable mounting of a tappet or a tappet guide receiving the tappet. The groove-shaped recess is preferably arranged in a base plate of the housing. This can be formed integrally with the housing or arranged on the housing as a separate component, for example in the form of a separate flange plate. The groove-shaped recess can be at least partially linear and/or curved. In a further preferred embodiment, the groove-shaped recess can also be in the form of a segment of a circle and/or form a complex curved path. The groove-shaped recess preferably has a homogeneous width.
Die Verstellmittel können Sicherungsmittel aufweisen, mittels derer der jeweilige Stößel und/oder eine den Stößel aufnehmende Stößelführung an dem Gehäuse und insbesondere an der nutförmigen Ausnehmung gegen verlieren gesichert ist. Die Sicherungsmittel können beispielsweise eine auf einen Außendurchmesser der Stößelführung angepasste flanschartige Sicherungsscheibe umfassen, welche in die nutförmige Ausnehmung eingreifen kann bzw. darin geführt ist. Alternative Sicherungsmittel können mittels Verstemmen der einzelnen Bauteile zueinander realisiert sein, so dass der Stößel bzw. die den Stößel aufnehmende Führung am Gehäuse gesichert ist.The adjusting means can have securing means, by means of which the respective ram and/or a ram guide accommodating the ram is secured against loss on the housing and in particular on the groove-shaped recess. The securing means can, for example, comprise a flange-like securing disk which is adapted to an outer diameter of the tappet guide and which can engage in the groove-shaped recess or is guided therein. Alternative security means can be realized by caulking the individual components to one another, so that the plunger or the guide receiving the plunger is secured to the housing.
Gemäß einer bevorzugten Ausführungsform ist wenigstens ein durch die Verstellmittel in seiner Position veränderbarer Stößel von den ihm zugeordneten Ankermitteln und/oder den ihm zugeordneten Spulenmittel axial entkoppelt. Dies bedeutet, dass die axiale Ausrichtung des Stößels nicht durch die axiale Ausrichtung der zugeordneten stationären Spulenmittel und/oder der axialen Ausrichtung der Ankermittel festgelegt ist. Vorzugsweise ist der jeweilige Stößel gegenüber den ihm zugeordneten stationären Spulenmittel und/oder den zugeordneten Ankermitteln der jeweiligen Aktuatoreinheit in eine Richtung senkrecht zur jeweiligen axialen Erstreckung, d.h. radial, verschiebbar angeordnet bzw. gelagert. Die beschriebene axiale Entkopplung kann auch für beide bzw. mehrere Stößel der Vorrichtung vorliegen sein.According to a preferred embodiment, at least one ram whose position can be changed by the adjustment means is axially decoupled from the anchor means assigned to it and/or the coil means assigned to it. This means that the axial orientation of the plunger is not determined by the axial orientation of the associated stationary coil means and/or the axial orientation of the armature means. The respective tappet is preferably arranged or mounted such that it can be displaced relative to the stationary coil means assigned to it and/or the associated anchor means of the respective actuator unit in a direction perpendicular to the respective axial extension, i.e. radially. The described axial decoupling can also be present for both or several rams of the device.
In einer bevorzugten Ausführungsform ist wenigstens einer der Stößel der Vorrichtung, mehr bevorzugt beide bzw. alle Stößel der Vorrichtung, gegenüber den zugeordneten stationären Spulenmitteln und/oder den zugeordneten Ankermitteln der jeweiligen Aktuatoreinheit exzentrisch angeordnet. Dies bedeutet, dass die jeweilige Stößelmittelachse nicht koaxial mit der jeweiligen Ankermittelachse bzw. einer Spulenmittelachse angeordnet ist. Ein Achsabstand der jeweiligen Stößel ist vorzugsweise kleiner als ein Achsabstand der zugeordneten Spulenmittel und/oder Ankermittel.In a preferred embodiment, at least one of the rams of the device, more preferably both or all rams of the device, is arranged eccentrically with respect to the associated stationary coil means and/or the associated anchor means of the respective actuator unit. This means that the respective center axis of the tappet is not arranged coaxially with the respective center axis of the armature or a center axis of the coil. A center distance of the respective tappet is preferably smaller than a center distance of the associated coil means and/or armature means.
In einer bevorzugten Ausführungsform ist der jeweilige Stößel mittels Magnetkraft an den Ankermitteln bzw. an einem sogenannten Scheibenpaket der Ankermittel verschiebbar gelagert bzw. haftet an diesen verschiebbar. Dies kann beispielsweise durch eine Magnetisierung eines den Ankermitteln zugeordneten Endes des Stößels und/oder der Ankermitteln bzw. des Scheibenpakets erfolgen. Der Stößel ist hierbei vorzugsweise in einer Richtung senkrecht zur Stößelrichtung an den Ankermitteln verschiebbar angeordnet.In a preferred embodiment, the respective tappet is slidably mounted on the anchoring means or on a so-called disc pack of the anchoring means by means of magnetic force or is slidably attached to them. This can be done, for example, by magnetizing an end of the plunger and/or the anchor means or the end associated with the anchor means Disk package done. In this case, the ram is preferably arranged to be displaceable on the anchoring means in a direction perpendicular to the direction of the ram.
In einer alternativen Ausführungsform ist der jeweilige Stößel fest mit den ihm zugeordneten Ankermitteln verbunden und die jeweiligen Ankermittel sind im Gehäuse gegenüber den zugeordneten stationären Spulenmitteln in eine Richtung senkrecht zur Stößelrichtung verschiebbar angeordnet bzw. gelagert.In an alternative embodiment, the respective plunger is firmly connected to the armature means assigned to it and the respective armature means are arranged or mounted in the housing such that they can be displaced relative to the assigned stationary coil means in a direction perpendicular to the direction of the ram.
In einer bevorzugten Ausführungsform weist die Stellvorrichtung eine gemeinsame Anschluss- oder Steckereinheit zur Bestromung der Spulenmittel der Aktuatoreinheiten auf. Diese ist vorzugsweise aus polymerem Material gebildet. Die Anschluss- oder Steckereinheit ist vorzugsweise integral am Gehäuse, d.h. nicht als separates Bauteil, ausgebildet.In a preferred embodiment, the adjusting device has a common connection or plug unit for energizing the coil means of the actuator units. This is preferably made of polymeric material. The connection or plug unit is preferably formed integrally on the housing, i.e. not as a separate component.
In einem weiteren Aspekt betrifft die Erfindung die Verwendung der elektromagnetischen Stellvorrichtung wie oben beschrieben, zur Montage an einem Verbrennungsmotor eines Kraftfahrzeugs zu dessen Nockenwellenverstellung.In a further aspect, the invention relates to the use of the electromagnetic adjusting device as described above for mounting on an internal combustion engine of a motor vehicle for adjusting its camshaft.
Zur Festlegung der Positionierung der Stößel der Vorrichtung im verbauten Zustand kann die Nockenwelle selbst oder ein der Nockenwelle vorgeschaltetes Bauteil dienen, beispielsweise eine separate Führungsplatte mit vordefinierten Passbohrungen, durch welches die Stößel und/oder die Stößelführungen in zueinander radial festgelegter Position geführt bzw. gelagert werden.The camshaft itself or a component upstream of the camshaft can be used to determine the positioning of the tappets of the device in the installed state, for example a separate guide plate with predefined fitting bores, through which the tappets and/or the tappet guides are guided or supported in a radially fixed position relative to one another .
