Reach into the yoke sheet Holding claws of a holding plate that the sheet metal plate on press the end of the yoke sheet. The bracket is again with the electromagnet on a magnetic coil carrier attached.
Ferner ist bereits aus der DE 198 05 404 A1 die Herstellung eines Jochbleches in Form eines kappenförmigen Tiefziehteils bekannt, das die Spulenwindungen am Umfang vollflächig umschließt und das auf eine Jochscheibe aufgesetzt ist.Furthermore, the production is already from DE 198 05 404 A1 a yoke sheet in the form of a cap-shaped deep-drawn part known that the coil turns over the entire surface encloses and which is placed on a yoke.
Ziel der Erfindung ist es, einen Elektromagneten der angegebenen Art mit möglichst einfachen Mitteln herstelltechnisch zu optimieren, ohne daß die Funktion des Magneten beeinträchtigt wird. The aim of the invention is to provide an electromagnet specified type with the simplest possible means to optimize manufacturing technology without the function of the Magnet is affected.
Diese Aufgabe wird erfindungsgemäß für den Elektromagneten der angegebenen Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is inventively for the electromagnet of the specified type through the characteristic features of the Claim 1 solved.
Weitere Merkmale, Vorteile und Anwendungsmöglichkeiten der Erfindung gehen im nachfolgenden aus der Beschreibung mehrerer Ausführungsbeispiele hervor.Other features, advantages and possible uses of the Invention follow from the description below several embodiments.
Es zeigen:Show it:
Fig. 1 eine Schnittdarstellung zweier Elektromagnete in einer Seitenansicht, die auf einem Ventilaufnahmekörper aufgesetzt sind, Fig. 1 is a sectional view of two electromagnets in a side view, which are mounted on a valve accommodating member,
Fig. 2 eine räumliche Darstellung des erfindungsgemäßen Jochblechs, Fig. 2 shows a spatial representation of the yoke plate according to the invention,
Fig. 3 eine räumliche Ansicht des funktionsfähig vorgefertigten, in der Fig. 1 links dargestellten Elektromagneten. Fig. 3 is a spatial view of the functional prefabricated electromagnet shown in Fig. 1 left.
Die Fig. 1 zeigt in einer erheblich vergrößerten Prinzipdarstellung im Querschnitt zwei nebeneinander angeordnete Elektromagnete 5, wobei jeder der beiden Elektromagnete 5 aus dem die Ventilspule 7 aufnehmenden Spulenwickelkörper 3 und dem rechteckförmig zusammengefalteten Jochblech 1 besteht. Die Elektromagnete 5 sind innerhalb eines die Elektromagnete 5 tragenden Gehäuses 7 angeordnet, das flüssigkeitsdicht auf einem mehrere Hydraulikventile aufweisenden Ventilaufnahmekörper 6 aufgesetzt ist. Hierzu erstreckt sich jeweils ein am Ventilaufnahmekörper 6 hervorstehender Hülsenkörper 2, der Teile eines Hydraulikventils, wie einen Magnetkern und einen Magnetanker beinhaltet, durch eine Öffnung 1b im Jochblech 1 in den Hohlraum des Spulenwickelkörpers 3, der zur elektromagnetischen Erregung mit am Spulenwickelkörper 3 hervorstehenden Einpreßkontakten (Spulenkontakte 8) an einer Leiterplatte 4' angeschlossen ist. Die Leiterplatte 4' ist im Gehäuse 7 ein Bestandteil eines elektronischen Steuergerätes. Die Leiterplatte 4' ruht auf einem Magnetspulenträger 4, an dem sich jeweils die Endabschnitt 1c des Jochblechs 1 abstützen können. Der Magnetspulenträger 4 besteht vorzugsweise aus einer Wärmeleitplatte, so daß die während der elektromagnetischen Erregung der Ventilspule 7 entstehende Wärme über das Jochblech 1 auf den Magnetspulenträger 4 abgeleitet werden kann. Fig. 1 shows, in a greatly enlarged schematic representation in cross-section two adjacently disposed electromagnets 5, wherein each of the two electromagnets 5 of the valve spool 7 receiving coil bobbin 3 and the rectangular folded yoke plate 1 is made. The electromagnets 5 are arranged within a housing 7 which carries the electromagnets 5 and which is placed in a liquid-tight manner on a valve receiving body 6 having a plurality of hydraulic valves. For this purpose, a sleeve body 2 protruding from the valve receiving body 6 , which contains parts of a hydraulic valve, such as a magnetic core and a magnet armature, extends through an opening 1 b in the yoke plate 1 into the cavity of the coil winding body 3 , which, for electromagnetic excitation, has press-in contacts protruding from the coil winding body 3 (Coil contacts 8 ) is connected to a circuit board 4 '. The circuit board 4 'is part of an electronic control unit in the housing 7 . The circuit board 4 'rests on a magnet coil support 4 , on which the end sections 1 c of the yoke plate 1 can be supported. The magnet coil carrier 4 preferably consists of a heat-conducting plate, so that the heat generated during the electromagnetic excitation of the valve coil 7 can be dissipated via the yoke plate 1 to the magnet coil carrier 4 .
Im vorliegenden Ausführungsbeispiel nach Fig. 1 sind am rechts abgebildeten Elektromagneten 5 die Endabschnitte 1c des Jochblechs 1 doppelt gefaltet, so daß sich im Bereich des Ventildoms, d. h. am Ende des Hülsenkörpers 2 eine besonders gute, verbreiterte Kontaktierung zur optimalen Gestaltung des Magnetkreises ergibt.In the present embodiment according to FIG. 1, the end sections 1 c of the yoke plate 1 are folded twice on the electromagnet 5 shown on the right, so that in the region of the valve dome, ie at the end of the sleeve body 2, there is a particularly good, widened contact for optimal design of the magnetic circuit.
Obwohl aus der Fig. 1 nicht ersichtlich, wird darauf hingewiesen, daß sich parallel zur Zeichnungsebene weitere Elektromagnete 5 und Hülsenkörper 2 befinden, die jeweils in einer Ventilreihe sehr kompremiert angeordnet sind, was durch die unmittelbar hintereinander gelegenen, von den Jochblechen 1 nicht umschlossenen und damit nicht versperrten Seitenwände der Spulenwickelkörper 3 gewährleistet wird. Der Abstand zwischen zwei benachbarten Elektromagneten 5 verringert sich folglich um die ansonsten gemäß dem Stand der Technik notwendige Abstandsvergrößerung nunmehr um die zweifache Wandstärke des Jochblechs 1.Although it is not apparent from FIG. 1, it is pointed out that there are further electromagnets 5 and sleeve bodies 2 parallel to the plane of the drawing, each of which is arranged in a very compressed manner in a row of valves, which is due to the fact that the yoke plates 1 are immediately adjacent and not enclosed and so that unlocked side walls of the bobbin 3 is guaranteed. The distance between two adjacent electromagnets 5 is consequently reduced by the distance enlargement otherwise necessary according to the prior art, now by twice the wall thickness of the yoke plate 1 .
Die bereits aus Fig. 1 bekannte vereinfachte Ausführung des Jochblechs 1 wird in einer räumlichen Darstellung in Fig. 2 hervorgehoben. Die Fig. 2 zeigt ein dünnwandiges, streifenförmiges Jochblech 1, das im Mittenabschnitt 1a eine Öffnung 1b zur Hindurchführung des Hülsenkörpers 2 aufweist. Die lichte Weite des Mittenabschnitts 1a ist an den Außendurchmesser des Spulenwickelkörpers 3 angepaßt, so daß die rechtwinklig nach oben abgeknickten Schenkel 1d unmittelbar die Wandung der Ventilspule 9 begrenzen. Die Höhe der Schenkel 1d ist wiederum an die Höhe des Spulenwickelkörpers 3 angepaßt, weshalb auch die rechtwinklig an den Schenkeln 1d abgeknickten Endabschnitte 1c auf der Oberseite des Spulenwickelkörpers 3 anliegen. Allerdings mit dem Unterschied gegenüber dem rechten Ausführungsbeispiel in Fig. 1, daß die Gesamtlänge des streifenförmigen Jochblechs 1 auf das aus der Höhe und dem Außendurchmesser des Spulenwickelkörpers 3 sich ergebende Umfangsmaß beschränkt ist, so daß sich die Kontaktierung der in den Endabschnitten 1c eingeformten Ausnehmungen 1e für den Hülsenkörper 2 auf die einfache Wandstärke des Jochblechs 1 beschränkt. Gut zu erkennen sind in Fig. 2 nicht nur die an die Kontur des Hülsenkörpers 2 angepaßten Ausnehmungen 1e, sondern auch die nach dem Endverformen des streifen- bzw. bandförmigen Jochblechs 1 verbliebene schlitzförmige Aussparung 1f zwischen den Endabschnitten 1c, die gemäß der nachfolgend beschriebenen Fig. 3 zur Durchführung der Spulenkontakte 8 dient.The simplified design of the yoke 1 already known from FIG. 1 is emphasized in a spatial representation in FIG. 2. Fig. 2 shows a thin-walled, strip-shaped yoke plate 1, which in the center portion 1a, an opening 1b for passage of the sleeve body 2 has. The clear width of the central portion 1 a is adapted to the outer diameter of the coil bobbin 3 , so that the right-angled upward leg 1 d directly limit the wall of the valve coil 9 . The height of the legs 1 d is in turn adapted to the height of the coil bobbin 3 , which is why the end portions 1 c bent at right angles to the legs 1 d rest on the upper side of the coil bobbin 3 . However, with the difference compared to the right embodiment in Fig. 1 that the total length of the strip-shaped yoke sheet 1 is limited to the circumferential dimension resulting from the height and the outer diameter of the coil bobbin 3 , so that the contacting of the recesses formed in the end sections 1 c 1 e for the sleeve body 2 limited to the simple wall thickness of the yoke sheet 1 . Easy to recognize not only adapted to the contour of the sleeve body 2 recesses 1 are shown in Fig. 2 e, but also the remaining after Endverformen the strip- or band-shaped yoke plate 1 slot-shaped recess 1 f between the end portions 1 c, which according to the subsequently described FIG. 3 is used to perform the coil contacts 8.
Die Fig. 3 verdeutlicht in räumlicher Darstellung die im rechteckförmigen Jochblech 1 integrierte Ventilspule 7 mit dem Spulenwickelkörper 3, aus dessen Oberseite im Bereich der schlitzförmigen Aussparung 1f die als Einpreßpfosten ausgebildeten Spulenkontakte 8 hervorstehen. Diese Spulenkontakte 8 werden zum Zwecke der in Fig. 1 gezeigten Anordnung durch den Magnetspulenträger 4 in die Öffnung der Leiterplatte 4' eingepreßt. Fig. 3 illustrates in a spatial representation in the integrated rectangular yoke plate 1 valve spool 7 with the coil bobbin 3, from the top thereof in the region of the slot-shaped recess 1f, the coil contacts 8 designed as press-in pins protrude. For the purpose of the arrangement shown in FIG. 1, these coil contacts 8 are pressed into the opening of the printed circuit board 4 'by the magnet coil support 4 .
Soweit nicht auf alle übrigen, aus der Abbildung ersichtlichen Merkmale eingegangen wird, entsprechen diese den vorangegangenen Erläuterungen zu den Fig. 1 und 2. Unless all the other features shown in the figure are dealt with, they correspond to the explanations given above for FIGS. 1 and 2.
Zusammenfassend zeichnet sich die anhand den Fig. 1 bis 3 dargestellte Erfindung durch folgende herstell- und funktionstechnisch vorteilhafte Merkmale aus:In summary, the invention shown with reference to FIGS. 1 to 3 is characterized by the following features that are advantageous in terms of production and function:
Das Jochblech 1 ist als Stanzbiegeteil aus einem einstückigen, den Magnetfluß leitenden Bandstahl hergestellt, dessen Mittenabschnitt 1a eine Öffnung 1b zur Hindurchführung des Hülsenkörpers 2 aufweist und dessen beide Endabschnitte 1c mit halbkreisförmigen Ausnehmungen 1e versehen sind, die an die Kontur des Hülsenkörpers 2 angepaßt sind.The yoke plate 1 is made as a stamped and bent part from a one-piece, the magnetic flux conductive steel strip, the central portion 1 a has an opening 1 b for the passage of the sleeve body 2 and the two end portions 1 c are provided with semicircular recesses 1 e, which to the contour of the sleeve body 2 are adjusted.
Der Durchmesser der Öffnung 1b ist an den Außendurchmesser des Hülsenkörpers 2 derart angepaßt, daß das Jochblech 1 spielfrei am Hülsenkörper 2 anliegt.The diameter of the opening 1 b is adapted to the outer diameter of the sleeve body 2 such that the yoke plate 1 rests against the sleeve body 2 without play.
Das Jochblech 1 ist mit seinen beiden Schenkeln 1d beiderseits der Öffnung 1b entsprechend dem Durchmesser und der Höhe des Spulenwickelkörpers 3 gleichsinnig um 4 × 90 Grad zu einem Rechteckprofil gefaltet.The yoke plate 1 is folded with its two legs 1 d on both sides of the opening 1 b in accordance with the diameter and the height of the coil bobbin 3 by 4 × 90 degrees to form a rectangular profile.
Die Länge des Jochblechs 1 ist an das aus der Höhe und dem Außendurchmesser des Spulenwickelkörpers 3 gebildeten Umfangsmaß angepaßt.The length of the yoke sheet 1 is adapted to the circumferential dimension formed from the height and the outer diameter of the coil bobbin 3 .
Die Breite beziehungsweise die Tiefe des Jochblechs 1 ist nicht größer gewählt als der Außendurchmesser des Spulenwickelkörpers 3.The width or the depth of the yoke sheet 1 is not chosen to be greater than the outer diameter of the coil winding body 3 .
Die Schenkeln 1d drücken kontaktfreudig mittels ihrer eigenen Vorspannkraft die beiden Endabschnitte 1c gegen den Hülsenkörper 2.The legs 1 d press the two end portions 1 c against the sleeve body 2 in a sociable manner by means of their own pretensioning force.
Es sind vorzugsweise mehrere Elektromagnete 5 zu einer Elektromagnetebaugruppe an einem Magnetspulenträger 4 zusammengefaßt, die als vormontierte Einheit auf einen mehrere Hydraulikventile aufnehmenden Ventilaufnahmekörper 6 aufgesetzt werden, wobei die Elektromagnete 5 derart in einer Reihe am Magnetspulenträger 4 angeordnet sind, daß die von den Jochblechen 1 nicht verschlossenen Seitenwände der Spulenwickelkörper 3 möglichst dicht nebeneinander gelegen sind.There are preferably a plurality of electromagnets 5 combined to form an electromagnet assembly on a solenoid carrier 4 , which are placed as a preassembled unit on a valve receiving body 6 accommodating a plurality of hydraulic valves, the electromagnets 5 being arranged in a row on the solenoid carrier 4 such that the yoke plates 1 do not closed side walls of the bobbin 3 are as close to each other as possible.
Schließlich ist es im Hinblick auf die Aufnahme der Montagekräfte und zur Wärmeableitung aus der Ventilspule 7 sinnvoll, daß die Jochbleche 1 mit ihren Endabschnitten 1c an dem steifen, den Wärmefluß leitenden Magnetspulenträger 4 anliegen. Finally, it is useful with a view to accommodating the mounting forces and heat dissipation from the solenoid coil 7, that the yoke plates 1 with their end portions 1 c of the rigid abut the flow of heat-conducting magnet coil carrier. 4
