Definitions

  • the present invention relates to a filter device for an internal combustion engine of a motor vehicle, according to the preamble of claim 1.
  • the invention also relates to a motor vehicle with an internal combustion engine having such a filter device.
  • Filter devices in particular so-called oil filters, are widely used in modern motor vehicles and serve, for example, for the purification of lubricants. Since such filter devices are usually not exposed to high temperatures, these could be formed at least in part from plastic, which can be cost-effective and at the same time reduced weight filter devices realized.
  • plastic filter devices a problem with such plastic filter devices is their connection, for example to an internal combustion engine of the motor vehicle. The connection must on the one hand reliable, that is fixed and on the other hand, a tight connection between the filter device on the one hand and the internal combustion engine, eg. A cylinder crankcase same, on the other hand.
  • the sometimes only insufficient creep resistance of the plastics has an effect here.
  • the present invention is concerned with the problem of providing an improved or at least another embodiment of a generic filter device, which is characterized in particular by an improved connection to an internal combustion engine.
  • the invention is based on the general idea to sandwich the filter device with a plastic housing and a stiffened, preferably metallic, connecting flange, via which the filter device can be braced against an internal combustion engine.
  • the connection flange thus lies between the internal combustion engine and the filter housing, wherein the connection flange also has a media transfer mechanism communicating with the filter device with corresponding supply / discharge lines or connections.
  • the stiffened Anitatisflansch thus assumes several tasks: First, by the stiffened construction of the same a solid and reliable connection to the engine can be achieved, the preferably metallic design of the Anitatisflanschs allows a strong tension of the same with the engine.
  • connection flange the entire supply / disposal mimic that supplies and discharges the filter device is integrated, whereby an attachment of the filter device according to the invention to the internal combustion engine is made extremely simple.
  • the assembly is carried out initially by connecting the filter housing to the connection flange, including self-drilling screws are used, which are screwed through the Anitatisflansch in the housing of the filter device, and then mounting the filter housing together with the Anitatisflansch on the engine.
  • this can be plugged together with the filter housing in a simple manner to appropriate connections on the engine, that is, in particular on the cylinder crankcase, and must be completely assembled Only about appropriate clamping means, for example.
  • Screws are braced against the engine. Due to the stiffened connection flange, which is preferably made of metal, creep can be almost completely excluded, which has often resulted in previous, completely made of plastic filter devices to a maintenance effort or to a Leckarge.
  • the stiffened connection flange is made of die-cast aluminum.
  • Aluminum die casting is a die casting process in which aluminum is pressed in a liquid or doughy state and under high pressure into a preheated steel mold. The pressed aluminum is held during the solidification process under pressure and after solidification by opening the die usually consisting of two halves die, de-shut.
  • alloying elements for example copper, iron or magnesium, are alloyed.
  • Aluminum has the great advantage that it has a high strength with corresponding alloying elements and thus ensures a reliable connection of the filter device to the internal combustion engine.
  • the filter device 1 can be designed, for example, as an oil filter and accordingly serve for the filtration of a lubricant in an internal combustion engine of a motor vehicle.
  • the filter device 1 according to the invention is clamped over the stiffened connection flange 3 according to the invention, so that in the fully assembled state, the connection flange 3 is located between the filter housing 2 and the internal combustion engine.
  • the connection flange 3 has one, with a not shown pure / raw space of the filter device 1 communicating media transfer mimic 4 with corresponding supply / discharge lines or terminals 5.
  • the stiffened Anitatisflansch 3 is made of metal, in particular of light metal, such as. An aluminum die-cast alloy formed.
  • a receptacle 6 is provided for a not-shown ring filter element, wherein the receptacle 6 can be screwed to a conventionally known filter housing cover and thus closed.
  • the connection flange 3 For connection of the filter housing 2 to the connection flange 3, not shown self-tapping or self-tapping screws may be provided, which are screwed through the connection flange 3 into the filter housing 2 of the filter device 1 and fix the filter housing 2 on the connection flange 3.
  • Possible locations for such self-tapping or self-tapping screws according to the Fig. 2 denoted by the reference numeral 7.
  • connection screws or generally clamping means are provided by means provided on the connection flange 3 clamping means 8 guides, which are formed, for example. In the form of through holes, plugged (see. Fig. 3 ).
  • the clamping device guides 8 may be formed, for example, as projecting bushes which engage in mounted filter housing in corresponding housing-side recesses 9 and at the same time with their respective free end 10 a stop for the clamping device to be screwed, for example. The screw.
  • the clamping means guides 8 are positioned such that the clamping means, for example the screws, carried out here permit a reliable and tight clamping of the connecting flange 3 and thus of the filter device 1 against the internal combustion engine.
  • at least one receptacle 6 'for a further functional element, such as, for example, an oil pressure sensor 11, may be integrated in the connecting flange 3.
  • the embodiments of the Anitatisflanschs 3 from stiffened, that is, solid material, offers the possibility of further functional elements, such as.
  • corresponding sealing grooves 12 may be provided on the connecting flange 3, in which corresponding seals, For example, ring seals, can be inserted.
  • corresponding seals For example, ring seals
  • sealing elements for example.
