Definitions

  • the present invention relates to an oil sump. More particularly, the present invention related to an oil sump having an oil filter.
  • Oil sumps known from the prior art typically have a separate filter placed in direct proximity to the oil sump floor, comprising at least one oil filter medium and one oil filter housing, which is preferably implemented as a suction oil filter. Oil sumps of this type having such an oil filter are known.
  • the filters disclosed above have the problem that complex fastening/fixing of the components to one another is necessary due to the separation of the components, such as the oil sump and oil filter in particular. A connection of these components is performed in the prior art by riveting, etc., for example.
  • oil filters placed separately in an oil sump have a gap between the filter bottom side and the interior side of the oil sump, which results in uncontrolled air suction and the generation of noise by movement of the loose filter in the oil sump. This results in a decrease of the filter efficiency and reduction of the usage comfort.
  • the filter is fastened permanently in the oil sump, for example, by welding/gluing, and is no longer removable.
  • These embodiments have the disadvantage that a separate replacement of the filter is not possible and a replacement of the oil sump/oil filter unit is thus very complex and costly.
  • Embodiments of the present invention provide an oil sump having an oil filter, which no longer has the disadvantages described above and/or in particular to disclose an oil sump, preferably made of metal or plastic, having an oil filter, in which the oil filter is permanently integratable, simultaneously, the number of the necessary components being reduced, the assembly being made easier, the costs for production and installation being reduced, undesired disadvantageous technical effects being reduced, and the filter being situated in the oil sump so it is easily replaceable as needed and thus is separable.
  • an oil sump according to Claim 1 in which the filter housing comprises an internal thread, which is implemented to receive the external thread of the oil drain screw and in which the filter housing is fastened on the oil sump at least partially via the oil drain screw, which closes the oil drain opening and engages using its external thread in the internal thread on the filter housing side.
  • An important aspect of the invention is thus to use the oil drain screw provided in the oil sump not only for closing the oil drain opening provided in the floor area of the oil sump, but rather simultaneously to fasten at least a part of the filter housing, in particular the filter housing bottom shell, and/or the filter housing top shell, on the oil sump via the oil drain screw.
  • an especially efficient and cost-effective positioning of at least a part of the oil filter housing is provided, because an oil drain screw is already provided as standard equipment in oil sumps according to the species.
  • the already known closure function of the oil drain screw has added a fastening function for fastening at least a part of the oil filter housing according to the invention. It is possible to provide further fasteners for fastening the filter housing. Fundamentally, however, an important aspect of the invention also allows the filter housing to be fastened on the oil sump solely via the oil drain screw.
  • an oil sump according to Claim 5 in which the filter housing has a clamping means, using which the filter housing is positioned and fastened in the oil sump, in such a way that the clamping means en-gages in a detent means situated on the oil sump side.
  • the filter housing bottom shell preferably comprises an internal thread, which is implemented to receive the external thread of the oil drain screw.
  • the filter housing thus also has a filter housing top shell, which is connected in a suitable way to the filter housing bottom shell.
  • further connection means preferably removable connection means, may be provided, such as detent means, in order to allow a replacement of the filter medium situated inside the filter housing.
  • both the filter housing bottom shell and also the filter housing top shell with a suitable internal thread, which are situated lying one above another in the installed state in the screwing-in direction of the oil drain screw, so that the oil drain screw fastens both the filter housing bottom shell and also the filter housing top shell on the oil sump.
  • the filter housing bottom shell is formed by a floor area of the oil sump and the filter housing top shell comprises an internal thread, which is implemented to receive the external thread of the oil drain screw.
  • a separate filter housing bottom shell is thus not necessary, because this function is achieved by a subarea of the oil sump floor.
  • the module to be fastened on the oil sump which is open on one side, thus comprises at least the filter housing top shell (and possibly also the filter medium).
  • the internal thread necessary for receiving the external thread of the oil drain screw is situated on the filter housing top shell.
  • the internal thread is preferably implemented so that it protrudes from the inner surface of the filter housing top shell and points in the direction toward the oil sump floor.
  • the internal thread and/or the part of the filter housing top shell forming the internal thread especially preferably projects far enough in the direction of the oil sump floor that this part of the filter housing top shell stands up on the oil sump floor and/or is in contact therewith in the installed state. In this way, the filter housing top shell is fastened especially well on the oil sump.
  • the oil sump has detent means, for example, and suitable clamping means are concurrently situated on the filter housing bottom shell and/or on the filter housing top shell, which are implemented in such a way that they engage in the detent means on the oil sump side to position the filter housing bottom shell and/or the filter housing top shell in the oil sump.
  • detent means for example, and suitable clamping means are concurrently situated on the filter housing bottom shell and/or on the filter housing top shell, which are implemented in such a way that they engage in the detent means on the oil sump side to position the filter housing bottom shell and/or the filter housing top shell in the oil sump.
  • the filter housing bottom shell may be fastened using the oil drain screw in the way described above and the filter housing top shell may be clamped via suitable clamping means, such as retention ribs, in detent means on the oil sump side, such as detent webs.
  • the filter unit comprises a receptacle, in particular a receptacle frame, which is implemented to receive the filter medium.
  • the receptacle may be a separate component, or may also be shaped into the oil sump.
  • a seal or an adhesive layer may be provided between the receptacle and the filter housing top shell and/or the oil sump floor, in order to achieve an especially tight connection.
  • clamping means such as retention ribs
  • clamping means may instead be used for positioning and fastening the filter inside the oil sump, which are implemented in such a way that they engage in detent means situated on the oil sump side, such as webs projecting toward the oil sump inner chamber.
  • detent means situated on the oil sump side, such as webs projecting toward the oil sump inner chamber.
  • Both the oil drain screw and also clamping means may be used for the removable fixing of the oil filter inside the oil sump.
  • Each of the cited fastening variants namely firstly via the oil drain screw or secondly via clamping means or thirdly via a combination of oil drain screw/clamping means, is applicable both for the one-piece embodiment of the filter housing, i.e., the filter medium is received by the filter housing top shell and the filter housing bottom shell is replaced by the floor area of the oil sump, and also for the two-piece embodiment of the filter housing, i.e., the filter medium is clamped between the filter housing top shell and bottom shell.
  • FIG. 1 shows a perspective lateral sectional view through an oil sump having an oil filter in a first embodiment.
  • FIG. 2 shows a perspective view of an oil sump having an oil filter in a second embodiment.
  • FIG. 3 shows a perspective sectional view of the oil sump from FIG. 2 along line A-A.
  • FIG. 4 shows a lateral sectional view of the oil sump from FIG. 2 or 3 .
  • FIG. 5 shows a perspective top view of an oil sump having an oil filter in a third embodiment.
  • FIG. 6 shows a sectional view of the oil sump from FIG. 5 along line B-B.
  • the oil sump 1 according to the first embodiment from FIG. 1 comprises an oil filter 2 , fastened on the oil sump 1 , having a filter housing top shell 3 , a filter housing bottom shell 4 , a filter medium 5 , which is clamped between the filter housing shells 3 and 4 , a filter outlet 6 , an oil drain screw 7 having sealing ring 8 and an external thread (not shown), and an internal thread (not shown) on the filter housing bottom shell, which is formed by a threaded bush 9 connected to the filter housing bottom shell.
  • the area around the oil drain screw 7 is also emphasized in a detail enlargement in FIG. 1 .
  • the two-piece filter housing made of filter housing top shell 3 , which is fastened on the filter housing bottom shell 4 , and filter housing bottom shell 4 is thus fastened solely via the internal thread of the threaded bush 9 , situated on the filter housing bottom shell 4 , in which the external thread of the oil drain screw 7 engages.
  • the oil drain screw 7 has to be removed. This procedure is also particularly advantageous, because an oil change also typically accompanies an oil filter change in practice.
  • the second embodiment according to FIGS. 2 , 3 , and 4 comprises an oil sump 1 ′, the filter housing top shell 3 ′, a filter medium 5 ′, a filter outlet 6 , an oil drain screw 7 having sealing ring 8 , a threaded bush 9 , fastened on the filter housing top shell side, having an internal thread (not shown), a filter shell seal 10 , a filter inlet 11 , a down-stream area 12 , and an upstream area 13 .
  • the receptacle 14 which is implemented as frame-like, for example, is used to receive the filter medium 5 ′ in this one-piece embodiment of the filter housing 20 .
  • the filter housing is partially formed by a floor area of the oil sump 1 ′.
  • the oil sump comprises the filter shell seal 10 , which is only interrupted in the area of the filter inlet 11 , in the contact area with the filter housing top shell 3 ′.
  • an internal thread is provided on the filter housing top shell 3 ′, which is formed by the threaded bush 9 fastened in the filter housing top shell 3 ′.
  • the threaded bush 9 is situated in an area projecting from the filter housing top shell 3 ′. This area projects far enough from the inner surface of the filter housing top shell 3 ′ that it stands up the floor area of the oil sump 1 ′ in the installed state according to FIG. 2 .
  • the positioning and fastening of the oil filter 2 on the oil sump 1 are not performed via the oil drain screw 7 , but rather via clamping means 15 which are situated on the filter housing 20 , independently of whether a one-piece or two-piece form of the filter housing 20 is provided, and en-gage in detent means 16 , such as detent webs, which are situated on the oil sump side.
  • These fasteners clamping means 15 and detent means 16
  • clamping means 15 and detent means 16 are preferably pro-vided on two opposing sides and thus allow fastening of the oil filter 2 within the oil sump 1 ′′ independently of the location of the oil drain screw 7 (not shown). Therefore, the actual position of the oil drain opening and/or the oil drain screw is not important for the fastening of the oil filter 2 .
  • the advantage thus results that in regard to the receptacle fastening, the position of the oil drain screw is freely selectable.
  • the oil drain screw 7 it is optionally possible to use the oil drain screw 7 (not shown) for positioning and fixing the oil filter 2 in addition to the clamping means 15 .
  • the integrated oil filter 2 is preferably a main stream oil filter used as a suction oil filter. It is also conceivable to implement the oil filter 2 having additional connections as a combination of a suction and pressure oil filter. It is also advantageous if needed to situate both main stream oil filter and also secondary stream oil filter in the shared filter housing 20 .
