Definitions

  • the invention relates to an oil pan with an attached oil filter unit according to the preamble of claim 1.
  • 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. Another fastening device is in the German patent application DE 10 2008 038 958 the same applicant described.
  • the object of the invention is to optimize the attachment of an oil filter unit to an oil pan.
  • 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.
  • 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.
  • a lubricant is in particular an engine oil and / or a transmission oil.
  • 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.
  • 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. 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.
  • the filter function of the magnet holder is independent of the attachment function.
  • 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.
  • 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.
  • the area in question may be e.g. be backed with such a magnetic material.
  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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 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.
  • 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.
  • 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 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.
  • 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.
  • 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 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 Vietnamese Embrace magnet holder 3a, as shown.
  • the oil pan 2 or the filter housing 11 may be formed of a non-magnetic material such as a plastic material or aluminum.
  • 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.
