Bei der betreffenden Ölwanne handelt es sich vorzugsweise um eine Ölwanne für Motoren und/oder Getriebe für Kraftfahrzeuge, Baufahrzeuge und dergleichen. Aus dem Stand der Technik ist es bekannt, an der Innenfläche einer Ölwanne eine Filtereinheit anzuordnen, die der Filtration des Motor- und/oder Getriebeöls dient und die mit der Ölwanne quasi ein System bildet.

Eine andere Befestigungsvorrichtung ist in der deutschen Patentanmeldung DE 10 2008 038 958 derselben Anmelderin beschrieben.The oil sump in question is preferably an oil sump for engines and / or transmissions for motor vehicles, construction vehicles and the like. From the prior art, it is known to arrange on the inner surface of an oil pan a filter unit which serves to filter the engine and / or transmission oil and which forms a system with the oil sump quasi. The attachment of the oil filter unit to the oil pan is done for example by means of a fastening device, as in the EP 10 2005 025 726 A1 the same applicant is described.

Die Aufgabe der Erfindung ist es, die Befestigung einer Ölfiltereinheit an einer Ölwanne zu optimieren.The object of the invention is to optimize the attachment of an oil filter unit to an oil pan.

Diese Aufgabe wird gelöst durch eine Ölwanne mit einer Ölfiltereinheit gemäß dem Anspruch 1. Vorteilhafte und bevorzugte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by an oil pan with an oil filter unit according to claim 1. Advantageous and preferred developments are the subject of the dependent claims.

Erfindungsgemäß wird eine Ölwanne für Motoren und/oder Getriebe vorgeschlagen, mit einer, d.h. wenigstens einer, an der Innenfläche angeordneten Filtereinheit zur Filtration von Motoren- und/oder Getriebeöl, wobei die Filtereinheit mittels wenigstens eines Magnethalters an der Ölwanne befestigt ist.According to the invention, an oil sump for engines and / or transmissions is proposed, with one, i. at least one, arranged on the inner surface of the filter unit for filtering motor and / or gear oil, wherein the filter unit is attached by means of at least one magnetic holder to the oil pan.

Eine Ölwanne dient der unteren Abdeckung eines Motors und/oder Getriebes. Die Ölwanne dient auch als Reservoir für das zur Schmierung und/oder Kühlung von Motor und/oder Getriebe benötigte Schmiermittel. Ein solches Schmiermittel ist insbesondere ein Motoröl und/oder ein Getriebeöl. Bevorzugt handelt es sich bei der Ölwanne um ein separates Bauteil, welches abnehmbar am Motor und/oder Getriebe gehaltert ist. Die Anordnung einer Filtereinheit im Inneren der Ölwanne bietet diverse Vorteile, wie z.B. eine hervorragende Bauraumausnutzung.An oil pan serves the lower cover of an engine and / or transmission. The sump also serves as a reservoir for the lubricant needed to lubricate and / or cool the engine and / or transmission. Such a lubricant is in particular an engine oil and / or a transmission oil. Preferably, the oil pan is a separate component, which is detachably mounted on the engine and / or gearbox. The arrangement of a filter unit inside the sump offers various advantages, such as an excellent space utilization.

Die an der Ölwanne befestigte Filtereinheit umfasst ein einteiliges oder mehrteiliges Filtergehäuse, in dem wenigsten ein Filtermedium angeordnet ist. Das Filtergehäuse weist wenigstens eine Öleinlassöffnung und wenigstens eine Ölauslassöffnung auf. Bei der Filtereinheit kann es sich um eine Saugölfiltervorrichtung handeln, bei welcher das zu filtrierende Öl von einer Pumpe beaufschlagt durch das Filtermedium gesaugt wird. Bei der Filtereinheit kann es sich aber auch um eine Druckölfiltervorrichtung handeln, bei der das zu filtrierende Öl von einer Pumpe beaufschlagt durch das Filtermedium gedrückt wird. Die erfindungsgemäße Befestigung der Filtereinheit an der Ölwanne erfolgt bevorzugt zwischen einem Abschnitt des Filtergehäuses und einem Abschnitt der Innenfläche bzw. Innenseite der Ölwanne, insbesondere derart, dass eine Unterseite des Filtergehäuses der Innenfläche der Ölwanne zumindest abschnittsweise zugewandt ist. Auch können sich die Unterseite des Filtergehäuses und die Innenfläche der Ölwanne punktuell berühren. Die Filtereinheit kann permanent oder auch auswechselbar an bzw. in der Ölwanne befestigt sein. Die erfindungsgemäße Befestigung mittels wenigstens eines Magnethalters soll jedoch dauerhafter Art sein, womit gemeint ist, dass auch über eine lange Betriebsdauer stets eine funktionssichere Befestigung gewährleistet ist.The attached to the oil pan filter unit comprises a one-piece or multi-part filter housing in which at least one filter medium is arranged. The filter housing has at least one oil inlet opening and at least one oil outlet opening. The filter unit may be a suction oil filter device in which the oil to be filtered is sucked by a pump through the filter medium. However, the filter unit may also be a pressure oil filter device in which the oil to be filtered is pressed by a pump through the filter medium. The attachment of the filter unit according to the invention to the oil sump is preferably effected between a section of the filter housing and a section of the inner surface or inside of the sump, in particular such that an underside of the filter housing faces the inner surface of the sump at least in sections. Also, the underside of the filter housing and the inner surface of the oil pan can touch selectively. The filter unit can be permanently or exchangeably attached to or in the oil sump. However, the attachment according to the invention by means of at least one magnetic holder should be permanent in nature, by which it is meant that a functionally reliable attachment is always ensured even over a long period of operation.

Im Sinne der Erfindung ist ein Magnethalter bzw. ein magnetischer Halter ein einteiliges oder mehrteiliges Bauteil, welches eine Befestigungsfunktion erfüllt. Wesentlich ist, dass dieses Bauteil permanentmagnetische Eigenschaften aufweist. Die Befestigungsfunktion kann unabhängig von diesen permanentmagnetischen Eigenschaften sein. Bevorzugt ist der Magnethalter zumindest teilweise aus einem permanentmagnetischen Material gebildet. Der Magnethalter kann vollständig aus einem solchen permanentmagnetischen Material gebildet sein. Ein solches permanentmagnetisches Material kann in einem Gehäuse eingebettet sein.For the purposes of the invention, a magnetic holder or a magnetic holder is a one-part or multi-part component, which fulfills a fastening function. It is essential that this component has permanent magnetic properties. The attachment function may be independent of these permanent magnetic properties. Preferably, the magnet holder is at least partially formed from a permanent magnetic material. The magnet holder may be formed entirely from such a permanent magnetic material. Such a permanent magnetic material may be embedded in a housing.

Eine Idee der Erfindung ist es, mit dem Magnethalter eine Befestigungseinrichtung bereitzustellen, die mehrere Funktionen wahrnehmen kann, wie diese insbesondere nachfolgend im Zusammenhang mit den Figuren im Einzelnen erläutert werden. So ist gemäß einer bevorzugten Weiterbildung vorgesehen, dass der Magnethalter gleichfalls zum Herausfiltern von metallischen Verunreinigungen (Urschmutz oder während des Betriebs auftretende Verschmutzungen aus einem magnetischen Metallmaterial) aus dem zu filtrierenden Motor- und/oder Getriebeöl dient. Hierbei werden die metallischen Verunreinigungen durch magnetische Kraft dauerhaft an den Magnethalter gebunden. Es kann von Vorteil sein, wenn der Magnethalter im Bereich einer Öleinlassöffnung des Filtergehäuses der Filtereinheit angeordnet ist, da dann das zu filtrierende Öl quasi am Magnethalter vorbeiströmen muss. Die Filterfunktion des Magnethalters ist jedoch unabhängig von der Befestigungsfunktion. In vorteilhafter Weise können die aus dem Stand der Technik bekannten Magnete zur Bindung metallischer Verunreinigungen für die erfindungsgemäße Lösung, d.h. für das Befestigen der Filtereinheit an der Ölwanne, herangezogen werden, was eine Bauteil- und Funktionsoptimierung, sowie Kostenoptimierung darstellt.One idea of the invention is to provide with the magnetic holder a fastening device which can perform a plurality of functions, as these are explained in detail below in particular in connection with the figures. Thus, according to a preferred embodiment, the magnet holder is likewise used for filtering out metallic contaminants (original dirt or contaminants from a magnetic metal material occurring during operation) from the engine and / or transmission oil to be filtered. Here, the metallic impurities are permanently bound by magnetic force to the magnet holder. It may be advantageous if the magnet holder in the region of an oil inlet opening of the filter housing of the filter unit is arranged, since then the oil to be filtered almost has to flow past the magnet holder. However, the filter function of the magnet holder is independent of the attachment function. Advantageously, the known from the prior art magnets for binding metallic contaminants for the inventive solution, ie for attaching the filter unit to the oil pan, are used, which is a component and function optimization, and cost optimization.

Gemäß einer bevorzugten Weiterbildung ist vorgesehen, dass ein Magnethalter eine magnetische Befestigung der Filtereinheit an der Ölwanne bewirkt. Die dem Magnethalter innewohnenden magnetischen Kräfte können in diesem Fall eine Doppelfunktion erfüllen, nämlich die Befestigung des Ölfiltereinheit an der Ölwanne und die Bindung metallischer Verunreinigungen im zu filtrierenden Motor- und/oder Getriebeöl, wie zuvor beschrieben. Die magnetische Befestigung gelingt besonders gut, wenn die Ölwanne und/oder das Filtergehäuse der Filtereinheit zumindest im Bereich der Befestigung mittels des Magnethalters aus einem magnetischen Material gebildet ist/sind. Alternativ kann der betreffende Bereich z.B. auch mit einem solchen magnetischen Material unterlegt werden.According to a preferred embodiment, it is provided that a magnet holder causes a magnetic attachment of the filter unit to the oil pan. The magnetic forces inherent in the magnet holder can in this case fulfill a dual function, namely the attachment of the oil filter unit to the oil sump and the binding of metallic contaminants in the engine and / or transmission oil to be filtered, as described above. The magnetic attachment succeeds particularly well when the oil pan and / or the filter housing of the filter unit is / are formed at least in the region of the attachment by means of the magnetic holder made of a magnetic material. Alternatively, the area in question may be e.g. be backed with such a magnetic material.

Alternativ und/oder ergänzend zur magnetischen Befestigung der Filtereinheit an der Ölwanne ist gemäß einer bevorzugten Weiterbildung vorgesehen, dass ein Magnethalter eine formschlüssige Befestigung der Filtereinheit an der Ölwanne bewirkt. Diese formschlüssige Befestigung gelingt besonders gut mittels von Formschlusselementen und insbesondere Rastelementen, die an dem Magnethalter ausgebildet sind und/oder die an der Ölwanne und/oder der Filtereinheit bzw. deren Filtergehäuse ausgebildet sind und die am Magnethalter angreifen. Solche Rastelemente können z.B. Rasthaken sein, die in korrespondierende Rastelemente oder Rastabschnitte eingreifen. Eine formschlüssige Befestigung mittels des Magnethalters ermöglicht, dass die Ölwanne und/oder das Filtergehäuse der Filtereinheit zumindest im Bereich der Befestigung mittels des Magnethalters aus einem nicht-magnetischen Material gebildet sein kann. Insbesondere kann das Filtergehäuse und/oder die Ölwanne zumindest bereichsweise aus einem Kunststoffmaterial oder Aluminiummaterial (oder dergleichen) gebildet sein. Prinzipiell sind unterschiedlichste Materialpaarungen von Filtergehäuse und Ölwanne möglich. Eine formschlüssige Befestigung ist jedoch auch bei Verwendung metallischer Materialien möglich und kann in diesem Fall die Befestigungsfunktion des Magnethalters vorteilhaft unterstützen.Alternatively and / or in addition to the magnetic attachment of the filter unit to the oil pan is provided according to a preferred development that a magnetic holder causes a positive attachment of the filter unit to the oil pan. This positive fastening succeeds particularly well by means of positive locking elements and in particular locking elements which are formed on the magnet holder and / or which are formed on the oil pan and / or the filter unit or its filter housing and which engage the magnet holder. Such locking elements may e.g. Be latching hooks which engage in corresponding locking elements or latching sections. A positive fastening by means of the magnet holder makes it possible for the oil sump and / or the filter housing of the filter unit to be formed from a non-magnetic material at least in the region of the fastening by means of the magnet holder. In particular, the filter housing and / or the oil pan can be formed at least in regions from a plastic material or aluminum material (or the like). In principle, a wide variety of material combinations of filter housing and oil sump are possible. However, a positive attachment is possible even when using metallic materials and can advantageously support the attachment function of the magnet holder in this case.

Gemäß einer bevorzugten Weiterbildung ist vorgesehen, dass die Lagepositionierung der Filtereinheit relativ zur Ölwanne durch Vertiefungen erfolgt, welche in die Ölwanne und/oder in das Filtergehäuse der Filtereinheit eingebracht sind und in die ein Magnethalter formschlüssig einsitzt. Ebenso ist es möglich, in der Ölwanne und/oder dem Filtergehäuse Erhöhungen auszubilden, auf welche ein Magnethalter formschlüssig aufgesteckt wird. Solche Erhöhungen können als Dome bezeichnet werden. Eine Vertiefung weist vom korrespondierenden Bauteil (Filtereinheit oder Ölwanne) weg, eine Erhöhung weist auf das korrespondierende Bauteil zu.According to a preferred embodiment, it is provided that the position positioning of the filter unit takes place relative to the oil pan by depressions, which are introduced into the oil pan and / or in the filter housing of the filter unit and in which a magnetic holder form-fitting seated. It is also possible to form elevations in the oil sump and / or the filter housing, onto which a magnetic holder is plugged in a form-fitting manner. Such elevations may be referred to as domes. A depression points away from the corresponding component (filter unit or oil sump), an increase points to the corresponding component.

Gemäß einer bevorzugten Weiterbildung ist vorgesehen, dass der Magnethalter an der Unterseite des Filtergehäuses und/oder an der Innenfläche der Ölwanne festgeklebt ist. Eine solche Verklebung führt eine dauerhafte Verbindung zwischen Magnethalter und Filtergehäuse und/oder Ölwanne herbei und erleichtert z.B. die Montage. Insbesondere kann der Magnethalter in einer Vertiefung oder auf einer Erhöhung (wie zuvor erläutert) festgeklebt sein. Eine solche Verklebung kann auch mit Formschlusselementen (wie oben erläutert) kombiniert werden. Anstelle einer Verklebung kann auch eine Verlötung, Verschweißung, Vernietung oder dergleichen vorgesehen sein. Eine Verklebung ist prinzipiell bei allen Materialien möglich, eignet sich insbesondere jedoch bei nichtmetallischen und nicht magnetischen Materialien, wie z.B. bei einer Kunststoff-Ölwanne oder einem Kunststoff-Filtergehäuse.According to a preferred embodiment, it is provided that the magnet holder is glued to the underside of the filter housing and / or on the inner surface of the oil pan. Such bonding leads to a permanent connection between magnet holder and filter housing and / or oil pan and facilitates e.g. the assembly. In particular, the magnet holder can be glued in a recess or on a raised portion (as explained above). Such a bond can also be combined with positive-locking elements (as explained above). Instead of a bond, a soldering, welding, riveting or the like may be provided. Bonding is possible in principle with all materials, but is particularly suitable for non-metallic and non-magnetic materials, such as e.g. in a plastic oil pan or a plastic filter housing.

Gemäß einer bevorzugten weiterbildung ist vorgesehen, dass der Magnethalter als Abstandshalter zwischen der Unterseite der Filtereinheit bzw. deren Filtergehäuse und der Innenfläche der Ölwanne dient. Hierdurch lässt sich mit geringem Aufwand ein Beabstandung der Unterseite des Filtergehäuses und der Innenfläche der Ölwanne herstellen, wodurch eine Unterströmung des Filtergehäuses ermöglicht wird. Hierdurch ist eine anzustrebende Positionierung der Öleinlassöffnung auf der Unterseite des Filtergehäuses möglich.According to a preferred embodiment, it is provided that the magnet holder serves as a spacer between the underside of the filter unit or its filter housing and the inner surface of the oil pan. This makes it possible to produce a spacing of the underside of the filter housing and the inner surface of the oil pan with little effort, whereby an underflow of the filter housing is made possible. As a result, an aspired positioning of the oil inlet opening on the underside of the filter housing is possible.

Gemäß einer bevorzugten Weiterbildung ist vorgesehen, dass der Magnethalter kreisringzylindrisch ausgebildet ist. D.h. der Magnethalter, weist eine obere kreisringförmige Stirnfläche und einer untere kreisringförmige Stirnfläche, sowie eine axiale Erstreckung zwischen diesen Stirnflächen auf. Die kreisringzylindrische Ausbildung führt zu großen Stirnflächen, die als Auflageflächen und/oder Stützflächen genutzt werden können, bei einem verhältnismäßig geringem Gewicht des Magnethalters. Ein weiterer Vorteil ist die Möglichkeit zur formschlüssigen Befestigung auf einem Dom, wie nachfolgend noch näher erläutert.According to a preferred embodiment, it is provided that the magnet holder is formed annular cylindrical. That the magnet holder, has an upper annular end face and a lower annular end face, and an axial extension between these end faces. The annular cylindrical design leads to large end faces, which can be used as bearing surfaces and / or support surfaces, with a relatively low weight of the magnet holder. Another advantage is the possibility for positive attachment to a dome, as explained in more detail below.

Fig. 1 zeigt in einer Explosionsdarstellung eine insgesamt mit 1 bezeichnete Filtereinheit, die mit ihrer Unterseite an der Innenfläche einer insgesamt mit 2 bezeichneten Ölwanne befestigt wird. Die Befestigung erfolgt mittels von zwei Magnethaltern 3. Die Anzahl von zwei Magnethaltern 3 ist lediglich beispielhaft. Die Magnethalter 3 sind kreisringzylindrisch ausgebildet, was einer bevorzugten Ausführungsform entspricht. Die kreisringzylindrischen Magnethalter 3 werden in kreisrunden Vertiefungen 22 in der Ölwanne 2 aufgenommen. Die Magnethalter 3 dienen neben der Befestigung der Filtereinheit 1 auch deren Beabstandung zur Ölwanne 2 im befestigten Zustand. Zur Beabstandung sind weiterhin mehrere als Dome ausgebildete Erhöhungen 23 in die ölwanne 2 eingeformt, an denen die Filtereinheit 1 unmittelbar an der Ölwanne 2 aufliegt. Fig. 1 shows in an exploded view a generally designated 1 filter unit, which is fastened with its underside on the inner surface of a total of 2 designated oil pan. The attachment takes place by means of two magnetic holders 3. The number of two magnetic holders 3 is merely exemplary. The magnet holder 3 are formed kreisringzylindrisch, which corresponds to a preferred embodiment. The circular cylindrical magnet holder 3 are received in circular wells 22 in the oil pan 2. The magnet holder 3 are used in addition to the attachment of the filter unit 1 and their spacing to the oil pan 2 in the attached state. For spacing, a plurality of elevations 23 formed as domes are furthermore formed in the oil pan 2, on which the filter unit 1 rests directly on the oil pan 2.

Fig. 2 zeigt die an der Ölwanne 2 befestigte Filtereinheit 1 in einer Schnittansicht. Die Filtereinheit 1 umfasst ein Filtergehäuse 11, das aus einem Gehäuseoberteil und aus einem Gehäuseunterteil gebildet ist, die an einem Flansch 12 miteinander gefügt sind. In dem von Gehäuseoberteil und Gehäuseunterteil eingeschlossenen Hohlraum ist ein Filtermedium zur Filtration von Öl, insbesondere von Motor- und/oder Getriebeöl, angeordnet. Das in der Ölwanne 2 befindliche und zu filtrierende Öl unterströmt hierzu das Filtergehäuse 11 und gelangt durch die Öleinlassöffnung 14 im Gehäuseunterteil ins Innere der Filtereinheit 1, wo es das Filtermedium durchströmt und hierbei gereinigt wird. Am Gehäuseoberteil ist ein Stutzen 13 angeordnet, an dessen oberen Ende sich eine Ölauslassöffnung für das filtrierte Öl befindet. Fig. 2 shows the attached to the oil pan 2 filter unit 1 in a sectional view. The filter unit 1 comprises a filter housing 11, which is formed from an upper housing part and a lower housing part, which are joined to one another at a flange 12. In the cavity enclosed by the upper housing part and the lower housing part, a filter medium for filtering oil, in particular engine and / or transmission oil, is arranged. The located in the oil pan 2 and to be filtered oil underflows for this purpose the filter housing 11 and passes through the oil inlet opening 14 in the lower housing part into the interior of the filter unit 1, where it flows through the filter medium and thereby cleaned. At the upper housing part, a nozzle 13 is arranged, at the upper end of which there is an oil outlet opening for the filtered oil.

Das Filtergehäuse 11 ist mittels der beiden Magnethalter 3 an der Innenfläche der Ölwanne 2 befestigt. Die Befestigung bzw. Halterung beruht auf magnetischen Haltekräften, die von den Magnethaltern 3 ausgehen, was jedoch nicht zwingend erforderlich ist, wie nachfolgend noch näher erläutert (im Zusammenhang mit der Fig. 3). Zur magnetischen Halterung sind sowohl das Gehäuseunterteil des Filtergehäuses 11 als auch die Ölwanne 2 aus einem magnetischen Material, insbesondere aus einem eisenhaltigen Material, gebildet. Die oberen Stirnflächen der Magnethalter 3 sind in unmittelbaren Kontakt mit dem Filtergehäuse 11 bzw. dem Gehäuseunterteil und die unteren Stirnflächen sind in unmittelbaren Kontakt mit der Innenfläche der Ölwanne 2. An den Kontaktflächen wird jeweils die magnetische Halterung herbeigeführt.The filter housing 11 is fixed by means of the two magnetic holder 3 on the inner surface of the oil pan 2. The attachment or holder is based on magnetic holding forces that emanate from the magnetic holders 3, but this is not absolutely necessary, as explained in more detail below (in connection with the Fig. 3 ). For magnetic support, both the lower housing part of the filter housing 11 and the oil pan 2 are made of a magnetic material, in particular of a ferrous material. The upper end surfaces of the magnet holder 3 are in direct contact with the filter housing 11 and the housing lower part and the lower end surfaces are in direct contact with the inner surface of the oil pan 2. At the contact surfaces each magnetic retention is brought about.

. Die Lagepositionierung der Filtereinheit 1 relativ zur Ölwanne 2 erfolgt gleichfalls über die Magnethalter 3. Hierzu sind die Magnethalter 3 in von der Filtereinheit 1 wegweisenden Vertiefungen 22 in der Ölwanne 2 angeordnet, welche die Magnethalter seitlich bzw. radial durch Formschluss positionieren. Am Gehäuseunterteil der Ölwanne 2 sind nach unten, d.h. in Richtung der Ölwanne 2, weisende Erhöhungen bzw. Dome 15 ausgebildet, welche formschlüssig und zentrierend in die axiale Mittelbohrung 31 der kreisringzylindrischen Magnethalter 3 eingreifen (formschlüssige Befestigung auf einem Dom, wie bereits oben erwähnt). Ebenso ist es auch möglich, Vertiefungen am Filtergehäuse 11 und Erhöhungen bzw. Dome an der Ölwanne 2 vorzusehen. Solche Vertiefungen und/oder Erhöhungen können als Fixierkonturen bezeichnet werden. Bevorzugt sind diese integral mit dem Filtergehäuse 11 und/oder der Ölwanne 2 ausgebildet., The positional positioning of the filter unit 1 relative to the oil sump 2 likewise takes place via the magnet holders 3. For this purpose, the magnet holders 3 are arranged in depressions 22 pointing away from the filter unit 1 in the oil sump 2, which position the magnet holders laterally or radially by positive locking. On the lower housing part of the oil pan 2 are down, i. in the direction of the oil pan 2, facing elevations or dome 15 is formed, which engage positively and centering in the axial central bore 31 of the circular cylindrical magnet holder 3 (positive attachment to a dome, as already mentioned above). Likewise, it is also possible to provide depressions on the filter housing 11 and elevations or dome on the oil pan 2. Such depressions and / or elevations may be referred to as fixing contours. Preferably, these are integrally formed with the filter housing 11 and / or the oil pan 2.

Über die Magnethalter 3 erfolgt ferner eine Beabstandung der Unterseite des Filtergehäuses 1 zur Innenfläche der Ölwanne 2. Ein typischer Beabstandungswert ist z.B. 2 bis 5 mm. Diese Beabstandung dient zur Bildung eines Spalts, der die Unterströmung des Filtergehäuses 11 mit dem zu filtrierenden Öl ermöglicht. Beim Unterströmen ist es vorteilhaft, dass das in die Öleinlassöffnung 14 einströmende Öl an den Magnethaltern 3 vorbeifließt oder diese umströmt, wobei die Magnethalter 3 magnetische Festpartikel aus dem Öl herausfiltern und an sich binden. Dies ist eine weitere Funktion der Magnethalter 3. Bevorzugt ist daher, dass die Magnethalter 3 im Bereich der Öleinlassöffnung 14 des Filtergehäuses 11 angeordnet werden und zwar derart, dass das in die Öleinlassöffnung 14 einströmende Öl in die magnetische Einflusszone der Magnethalter 3 gelangt. Die Beabstandung des Filtergehäuses 11 zur Innenfläche der Ölwanne 2 wird ferner durch mehrere in der Ölwanne 2 eingeformte Dome 23 herbeigeführt. Im Ergebnis wir damit eine Mehrpunktauflage für die Filtereinheit 1 erreicht, bei der das Filtergehäuse 11 unmittelbar und mittelbar, d.h. mittels der Magnethalter 3, an der Ölwanne anliegt. Da die Magnethalter 3 damit u.a. eine Beabstandungsfunktion und/oder Stützfunktion erfüllen, kann in vorteilhafter Weise die Anzahl der Dome 23 gegenüber den aus dem Stand der Technik bekannten Lösungen reduziert werden, oder es kann ggf. auch vollständig auf solche Dome 23 verzichtet werden, wodurch die Herstellungswerkzeuge einfacher gestaltet werden können und ein größerer Fließquerschnitt zur Unterströmung des Filtergehäuses 11 bereitsteht.Furthermore, a spacing of the lower side of the filter housing 1 from the inner surface of the oil sump 2 takes place via the magnet holders 3. A typical spacing value is e.g. 2 to 5 mm. This spacing serves to form a gap which allows the underflow of the filter housing 11 with the oil to be filtered. During underflow, it is advantageous for the oil flowing into the oil inlet opening 14 to flow past or flow around the magnet holders 3, the magnet holders 3 filtering out magnetic solid particles from the oil and binding them to themselves. This is a further function of the magnet holder 3. It is therefore preferred that the magnet holders 3 are arranged in the region of the oil inlet opening 14 of the filter housing 11 in such a way that the oil flowing into the oil inlet opening 14 enters the magnetic influence zone of the magnet holder 3. The spacing of the filter housing 11 to the inner surface of the oil pan 2 is further brought about by a plurality of molded in the oil pan 2 dome 23. As a result, we thus achieved a multipoint support for the filter unit 1, in which the filter housing 11 directly and indirectly, i. by means of the magnet holder 3, rests against the oil pan. Since the magnet holder 3 thus u.a. fulfill a spacing function and / or support function, advantageously, the number of domes 23 compared to the known from the prior art solutions can be reduced, or it may possibly be completely dispensed with such domes 23, whereby the manufacturing tools can be made simpler and a larger flow cross-section for underflow of the filter housing 11 is available.

Fig. 3 zeigt eine alternative Befestigungsmöglichkeit der Filtereinheit 1 an der Ölwanne 2 mittels wenigstens eines Magnethalters 3a. Die Befestigung bzw. Halterung beruht hierbei auf Formschlusselementen und zwar in der Form von federnden Rasthaken 17 und 25, die an der Unterseite der Filtereinheit 1 bzw. dem Gehäuseunterteil und der Ölwanne 2 angeordnet sind und die formschlüssig den Innenumfangsrand und den Außenumfangsrand des kreisringzylindrischen Magnethalters 3a umgreifen, wie abgebildet. In diesem Fall kann die Ölwanne 2 oder das Filtergehäuse 11 aus einem nicht-magnetischen Material, wie z.B. einem Kunststoffmaterial oder aus Aluminium, gebildet sein. Um Platz für das Hintergreifen der Rastnasen am Magnethalter 3a bereitzustellen, sind Abstandselemente 41 und 42 vorgesehen, die als separate Elemente ausgebildet oder auch einstückig mit dem Filtergehäuse 11, der Ölwanne 2 und/oder dem Magnethalter 3a ausgebildet sein können. Alternativ können die Formschlusselemente 17 und 25 im Übrigen auch am Magnethalter 3a ausgebildet bzw. an diesem angeordnet sein. Obwohl bei dieser Befestigungsmöglichkeit die magnetische Haltfunktion entfällt oder ggf. ein untergeordnete Rolle spielt, bleiben die anderen, oben erläuterten Funktionen des Magnethalters 3, insbesondere die Abstandshaltung und die Partikelrückhaltung, im Wesentlichen erhalten. Fig. 3 shows an alternative attachment possibility of the filter unit 1 to the oil pan 2 by means of at least one magnetic holder 3a. The attachment or holder is based on positive locking elements in the form of resilient latching hooks 17 and 25 which are arranged on the underside of the filter unit 1 and the lower housing part and the oil pan 2 and the form-fitting the inner peripheral edge and the outer peripheral edge of kreisringzylindrischen Embrace magnet holder 3a, as shown. In this case, the oil pan 2 or the filter housing 11 may be formed of a non-magnetic material such as a plastic material or aluminum. In order to provide space for the engagement of the locking lugs on the magnet holder 3a, spacer elements 41 and 42 are provided, which may be formed as separate elements or integrally formed with the filter housing 11, the oil pan 2 and / or the magnet holder 3a. Alternatively, the form-locking elements 17 and 25 can also be formed on the magnet holder 3a or arranged on the latter. Although in this mounting option, the magnetic holding function is eliminated or possibly plays a minor role, the other, above-mentioned functions of the magnet holder 3, in particular the spacing and the particle retention, are substantially retained.
