  • 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.
  • 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.
  • the filter unit can be permanently or exchangeably attached to or in the oil sump.
  • 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.
  • 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.
  • 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.
  • 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.
  • metallic impurities are permanently bound by magnetic force to the magnet holder.
  • the magnet holder is arranged in the region of an oil inlet opening of the filter housing of the filter unit, since then the oil to be filtered has to flow past the magnet holder, as it were.
  • the filter function of the magnet holder is independent of the attachment function.

  • Such locking elements can, for. B. locking 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.
  • 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).
  • a wide variety of material combinations of filter housing and oil sump are possible.
  • a positive attachment is possible even when using metallic materials and can advantageously support the attachment function of the magnet holder in this case.
  • 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 is positively 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.
  • 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, for. B. the assembly.
  • 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).
  • a soldering, welding, riveting or the like may be provided. Bonding is possible in principle for all materials, but is particularly suitable for non-metallic and non-magnetic materials such. B. in a plastic oil pan or a plastic filter housing.
  • 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.
  • 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 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 nikringzylindrisch, 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.
  • 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 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.
  • a filter medium for filtering oil in particular engine and / or transmission oil
  • 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.
  • a nozzle 13 is arranged, at the upper end of which there is an oil outlet opening for the filtered oil.
  • 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 ).
  • 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.
  • the positional positioning of the filter unit 1 relative to the oil sump 2 likewise takes place via the magnet holders 3.
  • 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 housing bottom of the oil pan 2 are facing 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).
  • Such depressions and / or elevations may be referred to as fixing contours.
  • these are integrally formed with the filter housing 11 and / or the oil pan 2.
  • 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 z. B. 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.

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.
  • 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 the circular cylindrical magnet holder 3a embrace as shown.
  • the oil pan 2 or the filter housing 11 made of a non-magnetic material, such. As a plastic material or aluminum, be formed.
  • 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.
  • the form-locking elements 17 and 25 can also be formed on the magnet holder 3a or arranged on the latter.
