Elektromagnet electromagnet
Die Erfindung betrifft einen Elektromagnet, insbesondere Schaltmagnet, mit einer auf einem Spulenkörper befindlichen Erregerwicklung und einem ein Teil des magnetischen Rückschlusses bildenden Polstück, wobei innerhalb des Spulenkörpers ein Polkern und ein axial beweglicher Magnetkolben vorgesehen sind, das Polstück an dem dem Polkern entgegengesetzten Bereich eine Durchgangsöffnung für den Magnetkolben bildet und dieser für seine Bewegung in einer Führung des Polkerns gelagert ist. The invention relates to an electromagnet, in particular switching magnet, having a coil body on an exciter winding and a part of the magnetic yoke forming pole piece, wherein inside the bobbin, a pole core and an axially movable magnetic piston are provided, the pole piece at the pole core opposite region a through hole forms for the magnetic piston and this is stored for its movement in a guide of the pole core.
Ein Elektromagnet dieser Art ist aus dem Dokument EP 1 818 951 BT be- kannt. Für die Betriebseigenschaften derartiger Magnete ist der magnetische Rückschluss zwischen Polstück und Magnetkolben von großer Bedeutung. Die Eigenschaft dieses Rückschlusses hängt von der Gestaltung des zwischen Magnetkolben und Polstück befindlichen Luftspaltes ab. Allgemein führt ein geringer Luftspalt zwischen Magnetkolben und Polstück zu einer Erhöhung der Magnetkraft über Hub. In dem genannten Dokument sind hinsichtlich der Gestaltung des Luftspaltes mehrere Lösungen aufgezeigt, die sämtliche auf Maßnahmen der Formgebung des Magnetkolbens an dessen der Durchgangsöffnung am Polstück benachbarten Ende basieren. Dabei handelt es sich um Verjüngungen am Endabschnitt des Kolbens oder um eine Verkürzung des Kolbens derart, dass dessen Endfläche die Durchgangsöffnung nicht völlig durchgreift. Bei den bekannten Lösungen lässt das Betriebsverhalten zu wünschen übrig. Im Hinblick hierauf liegt der Erfindung die Aufgabe zugrunde, einen Elektromagnet zur Verfügung zu stellen, der sich durch eine vergleichsweise verbesserte Magnetkraft-Hub-Kennlinie auszeichnet. An electromagnet of this kind is known from the document EP 1 818 951 BT. For the operating characteristics of such magnets, the magnetic inference between the pole piece and magnetic piston is of great importance. The property of this inference depends on the design of the air gap located between magnetic piston and pole piece. In general, a small air gap between the magnetic piston and the pole piece leads to an increase in the magnetic force via stroke. In said document, several solutions are shown in terms of the design of the air gap, all based on measures of the shaping of the magnetic piston at its the through hole adjacent the pole piece end. These are tapers at the end portion of the piston or a shortening of the piston such that its end face does not fully penetrate the passage opening. In the known solutions, the performance leaves much to be desired. In view of this, the invention has for its object to provide an electromagnet available, which is characterized by a comparatively improved magnetic force-stroke characteristic.
Erfindungsgemäß ist diese Aufgabe durch einen Elektromagnet gelöst, der die Merkmale des Patentanspruches 1 in seiner Gesamtheit aufweist. According to the invention this object is achieved by an electromagnet having the features of claim 1 in its entirety.
Demgemäß besteht eine Besonderheit der Erfindung darin, dass ein die Be- triebseigenschaften des Elektromagneten maßgeblich bestimmender parasitärer Luftspalt in der Weise gebildet ist, dass das Polstück, anschließend an ein das axiale Ende des Spulenkörpers teilweise übergreifendes Flanschteil ein Büchsenteil bildet, das sich in Form eines Hohlzylinders in den Spulenkörper erstreckt und einen Längenabschnitt des Magnetkolbens übergreift, wobei zwischen der Innenwand des Hohlzylinders und dem Umfang des Kolbens ein parasitärer Luftspalt ausgebildet ist. Durch Wahl des Unterschiedes zwischen Innendurchmesser des Hohlzylinders des Büchsenteiles und Außendurchmesser des Kolbens lässt sich die Spaltweite auf einen optimalen Wert einstellen. Im Unterschied zu den dem Stand der Technik ent- sprechenden Lösungen ergibt sich bei Kolbenbewegungen keinerlei Veränderungen der Spaltgeometrie, so dass eine optimale Kraft-Hub-Kennlinie realisierbar ist. Accordingly, a peculiarity of the invention resides in the fact that a parasitic air gap which decisively determines the operating properties of the electromagnet is formed such that the pole piece subsequently forms a bushing part in the form of a flange part which partially overlaps the axial end of the coil former Hollow cylinder extends into the bobbin and engages over a longitudinal portion of the magnetic piston, wherein between the inner wall of the hollow cylinder and the circumference of the piston, a parasitic air gap is formed. By selecting the difference between the inner diameter of the hollow cylinder of the sleeve part and the outer diameter of the piston, the gap width can be set to an optimum value. In contrast to the prior art solutions resulting in piston movements no changes in the gap geometry, so that an optimal force-stroke curve is feasible.
Bei besonders vorteilhaften Ausführungsbeispielen ist der Magnetkolben auf einer Führungshülse in einer Gleitpassung gelagert, deren Koaxialität zum Hohlzylinder des Polstückes derart eng toleriert ist, dass der Magnetkolben bei einer Weite des parasitären Luftspaltes von weniger als 0,1 mm vom Hohlzylinder berührungsfrei bleibt. Eine Berührung zwischen Magnetkolben und Polstück würde durch Reibung zu einer erhöhten Hysterese in der Magnetkraft-Hub-Kennlinie führen und muss daher unbedingt vermieden werden. Dank der erfindungsgemäß vorgesehenen, eng tolerierten Koaxiali- tat der Führung im Polkern und der Führungshülse eröffnet sich die Möglichkeit, die Weite des parasitären Luftspaltes zu minimieren, ohne die Gefahr einer Berührung in Kauf nehmen zu müssen. In besonders vorteilhafter Weise kann die Anordnung so getroffen sein, dass ein zweites Polstück, das als Gleichteil des ersten Polstückes ausgebildet ist, an dem der Durchgangsöffnung entgegengesetzten Bereich angeordnet ist und mit seinem Büchsenteil den Festsitz für den im Hohlzylinder gelagerten Polkern bildet. Der Einsatz von zwei baugleichen Polstücken eröffnet die Möglichkeit, den Einzelteilepreis durch die doppelte Stückzahl zu minimieren, so dass das Endprodukt in kostengünstiger Weise herstellbar ist. In particularly advantageous embodiments, the magnetic piston is mounted on a guide sleeve in a sliding fit whose coaxiality with the hollow cylinder of the pole piece is so closely tolerated that the magnetic piston remains free of contact with a width of the parasitic air gap of less than 0.1 mm from the hollow cylinder. A contact between magnetic piston and pole piece would lead by friction to increased hysteresis in the magnetic force-stroke curve and must therefore be avoided at all costs. Thanks to the tight toleranced coaxial did the leadership in Polkern and the guide sleeve opens the possibility to minimize the width of the parasitic air gap without having to accept the risk of contact. In a particularly advantageous manner, the arrangement can be made such that a second pole piece, which is formed as a common part of the first pole piece, is disposed on the opposite side of the passage opening and forms with its sleeve part the tight fit for the pole core mounted in the hollow core. The use of two identical pole pieces opens up the possibility of minimizing the item price by twice the number of pieces, so that the end product can be produced in a cost-effective manner.
Hinsichtlich der Gestaltung des weiteren magnetischen Rückschlusses kann die Anordnung mit Vorteil so getroffen sein, dass ein die Wicklung zumin- dest teilweise umgebender magnetischer Rückführmantel einen magnetischen Rückschluss zum Flanschteil des betreffenden Polstückes bildet. Derartige Ausführungsbeispiele zeichnen sich durch eine bei geringer Baugröße vergleichsweise hohe Magnetkraft aus. Eine besonders rationelle Herstellung ermöglichen Ausführungsbeispiele, bei denen Spulenkörper, Polstück und Rückführmantel zur Bildung einer festen Einheit durch eine Kunststoff-Umspritzmasse umspritzt sind, die ein einheitliches Gehäuse bildet. Nachstehend ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles im Einzelnen erläutert. Es zeigen: With regard to the design of the further magnetic return path, the arrangement can advantageously be such that a winding at least partially surrounding magnetic return jacket forms a magnetic inference to the flange of the respective pole piece. Such embodiments are characterized by a small size comparatively high magnetic force. A particularly rational production allow embodiments in which bobbin, pole piece and return jacket to form a solid unit are encapsulated by a plastic Umspritzmasse, which forms a unitary housing. The invention with reference to an embodiment shown in the drawing will be explained in detail. Show it:

Die Erfindung ist nachstehend anhand eines Beispieles erläutert, bei dem der Elektromagnet innerhalb eines Gehäuses 1 das Betätigungselement für eine Ventileinrichtung bildet, die im Gehäuse 1 in einer Ventilkammer 3 angeordnet ist, die in der Zeichnung weggelassen ist, weil die Ventileinrichtung nicht Teil der Erfindung bildet. Das Gehäuse 1 ist aus einer Kunststoff- Umspritzmasse 5 einteilig ausgebildet, mit der der Spulenkörper 7 sowie die weiteren Komponenten des Elektromagneten umspritzt sind. The invention will now be described by way of example in which the electromagnet within a housing 1 forms the actuating element for a valve device, which is arranged in the housing 1 in a valve chamber 3, which is omitted in the drawing, because the valve device does not form part of the invention , The housing 1 is integrally formed from a plastic Umspritzmasse 5, with which the bobbin 7 and the other components of the electromagnet are encapsulated.
Um beim Umspritzen eine gasdichte Verbindung zwischen Umspritzmasse und Spulenkörper zu gewährleisten, sind, wie in der vergrößerten Darstellung von Fig. 3 deutlicher erkennbar ist, am Spulenkörper 7 Zacken 9 ge- bildet, die beim Umspritzvorgang sogenannte Abschmelzkanten bilden. Die auf dem Spulenkörper 7 befindliche Erregerwicklung 1 1 ist in der bei derartigen Elektromagneten üblichen Weise von einem ein Teil des magnetischen Rückschlusses bildenden Rückführmantel 1 3 umgeben, der, ebenso wie zur Bestromung der Wicklung 1 1 dienende Flachstecker 1 5 in die Um- spritzmasse 5 eingebettet ist. In order to ensure a gas-tight connection between encapsulation compound and bobbin during encapsulation, as shown in the enlarged view of Fig. 3 is clearly recognizable, formed on the bobbin 7 spikes 9, which form so-called Abschmelzkanten the encapsulation. The excitation winding 1 1 located on the bobbin 7 is surrounded in the usual manner with such electromagnets by a part of the magnetic yoke forming return jacket 1 3, which, as well as for energizing the winding 1 serving 1 flat plug 1 5 in the transfer molding compound fifth is embedded.
An dem der Ventilkammer 3 zugewandten Bereich befindet sich innerhalb des Spulenkörpers 7 ein fest angeordneter Polkern 1 7, relativ zudem im Inneren des Spulenkörpers 7 ein Magnetkolben 19 axial beweglich ange- ordnet ist. In der Darstellung von Fig. 1 und 3 ist der Magnetkolben 19 in der Position seines an den Polkern 1 7 angenäherten Hubendes dargestellt, bei dem sich eine mit dem Magnetkolben 19 zusammenwirkende Führungshülse 21 , in der ein nicht näher dargestellter Betätigungsstößel aufnehmbar ist, der für die Steuerung der nicht gezeigten Ventileinrichtung vorgesehen ist, in ihrer in der Zeichnung am weitesten links gelegenen Stel- lung befindet. Wenn es sich um einen sogenannten„drückenden" Elektromagneten handelt, entspricht diese Kolbenstellung dem voll bestromten Zustand der Erregerwicklung 1 1 , anderenfalls ist der Magnetkolben 19 durch Bestromen aus der gezeigten Endposition nach rechts bewegbar. Für die Fortsetzung des magnetischen Rückschlusses vom Rückführmantel 13 ins Innere des Spulenkörpers 7 sind als Gleichteile ausgebildete Polstücke 23 vorgesehen, von denen ein erstes Polstück 23 im Bereich des Magnetkolbens 19 eine Durchgangsöffnung 25 bildet, innerhalb deren der Magnetkolben 19 bewegbar ist. Jedes der Polstücke 23 weist ein Flanschteil 27 auf, das das zugewandte axiale Ende des Spulenkörpers 7 so übergreift, dass es sich bis in die Nähe des Rückführmantels 13 erstreckt. Vom On the region facing the valve chamber 3, a fixedly arranged pole core 1 7 is located inside the bobbin 7, relative to which a magnetic piston 19 is disposed axially movably in the interior of the bobbin 7. In the illustration of Fig. 1 and 3, the magnetic piston 19 is shown in the position of his approach to the pole core 1 7 stroke end, in which a guide sleeve 21 cooperating with the magnetic piston 19, in which an actuating tappet (not shown in more detail) can be received, which is provided for the control of the valve device (not shown), is in its leftmost position in the drawing. If this is a so-called "pushing" electromagnet, this piston position corresponds to the fully energized state of the exciter winding 11, otherwise the magnetic piston 19 can be moved to the right by energizing from the end position shown, for the continuation of the magnetic return from the return jacket 13 to the interior of the bobbin 7 are formed as identical parts pole pieces 23, of which a first pole piece 23 forms a through hole 25 in the region of the magnetic piston 19, within which the magnetic piston 19 is movable of the bobbin 7 engages over so that it extends into the vicinity of the return jacket 13. Vom
Flanschteil 27 erstreckt sich ein Büchsenteil 29 ins Innere des Spulenkörpers 7. Das Büchsenteil 29 bildet einen Hohlzylinder, der sich bei dem ersten Polstück 23 über einen Längenabschnitt des Kolbens 19 und beim zwei- ten Polstück 23 über einen Längenabschnitt des Polkernes 1 7 erstreckt. In diesem Längenabschnitt des zweiten Polstückes 23 ist der Polkern 1 7 durch Festsitz festgelegt. Die Innenwand des Hohlzylinders am ersten Polstück 23 befindet sich vom Umfang des Magnetkolbens 19 jedoch in einem kleinen parasitären Luftspalt 30 bildenden Abstand, wobei die Spaltweite weniger als 0,1 mm beträgt. Beim vorliegenden Ausführungsbeispiel beträgt die Differenz zwischen dem Außendurchmesser des Magnetkolbens 19 und dem Innendurchmesser des Hohlzylinders des Büchsenteiles 29 beispielsweise 0,07mm. Eine derart minimierte Spaltweite, ohne dass hierbei die Gefahr einer Berührung des Magnetkolbens 19 besteht, was zu einer erhöhten Hysterese und damit zu einer Betriebsstörung führen würde, ist bei der Erfindung dadurch auf sichere Weise realisierbar, dass der Magnetkolben 19 mit seiner Führungshülse 21 in einer eng tolerierten Gleitpassung am Polkern 1 7 verschiebbar gelagert ist und dass eine eng tolerierte Koaxialität der Hohlzy- linder beider Büchsenteile 29 der Polstücke 23 eingehalten wird. Dies wird dadurch erreicht, dass bei dem Umspritzprozess, bei dem die in Fig. 2 gezeigte Fertigungsstufe erreicht wird, in dem in Fig. 2 noch offenen Innenraum des Spulenkörpers 7 ein kalibrierter Umspritzdorn (nicht dargestellt) zum Einsatz gebracht wird, wodurch die Koaxialität zwischen den Hohlzy- lindern der Büchsenteile 29 beider Polstücke 23 kleiner als 0,07mm gehalten werden kann. Dergestalt ist auch eine insgesamt druckdichte Anordnung für den Magneten als Ganzes erreicht. Wie des weiteren die Fig. 1 und 3 zeigen, ist zwischen dem Außenumfang der Führungshülse 21 und dem zugewandten Innenumfang des Magnetkolbens 19 noch eine zylindri- sehe Führungsbuchse eingesetzt, die jedoch, wie dargestellt, nicht völlig bis zum Boden des Magnetkolbens 19 fortgeführt ist. Ferner ist die Führungsbuchse über eine absatzartige Verringerung des Durchmessers im Magnetkolben 19 gehalten, die in Blickrichtung auf die Figuren nach rechts gesehen in den Boden des Magnetkolbens 19 übergeht an dem sich die Füh- rungshülse 21 abstützt. Flange part 27 extends a bushing part 29 into the interior of the bobbin 7. The bushing part 29 forms a hollow cylinder which extends over a length portion of the piston 19 and at the second Polstück 23 over a longitudinal portion of the Polkernes 1 7 at the first pole piece 23. In this length portion of the second pole piece 23 of the pole core 1 7 is fixed by interference fit. However, the inner wall of the hollow cylinder on the first pole piece 23 is spaced from the circumference of the magnetic piston 19 in a small parasitic air gap 30, wherein the gap width is less than 0.1 mm. In the present embodiment, the difference between the outer diameter of the magnetic piston 19 and the inner diameter of the hollow cylinder of the sleeve member 29, for example, 0.07mm. Such a minimized gap width without the risk of touching the magnetic piston 19, resulting in increased hysteresis and thus would lead to a malfunction is in the invention in a safe manner realized that the magnetic piston 19 is slidably mounted with its guide sleeve 21 in a tight tolerance sliding fit on the pole core 1 7 and that a closely toleranced coaxiality of the hollow cylinder of both sleeve parts 29 of the pole pieces 23 is maintained. This is achieved by the fact that in the overmolding process, in which the manufacturing stage shown in FIG. 2 is achieved, a calibrated Umspritzdorn (not shown) is used in the in Fig. 2 still open interior of the bobbin 7 is used, whereby the coaxiality between the hollow cylinders of the sleeve parts 29 of both pole pieces 23 can be kept smaller than 0.07 mm. In this way, an overall pressure-tight arrangement for the magnet as a whole is achieved. As further shown in FIGS. 1 and 3, between the outer periphery of the guide sleeve 21 and the facing inner periphery of the magnetic piston 19 is still a cylindrical see guide bushing used, however, as shown, not completely continued to the bottom of the magnetic piston 19. Furthermore, the guide bush is held over a shoulder-like reduction of the diameter in the magnetic piston 19, which, viewed in the direction of the figures, passes into the bottom of the magnetic piston 19 to the right, on which the guide sleeve 21 is supported.
