Definitions

  • the invention relates to an anti-skid module for an air filter according to claim 1, an air filter for a motor vehicle according to claim 5, in which an anti-skid module is insertable, an air filter according to claim 8, in which an anti-skid module is inserted, and an air filter according to claim 9.
  • an air filter is included in the intake system.
  • the raw air may contain snow under appropriate climatic conditions.
  • the snow may collect in the intake system, in the air filter or on the air filter element and cause increased pressure loss or occlusion of the intake system. Other contaminants can also cause a flow reduction of the primary intake.
  • Intake systems for motor vehicles in regions with snowfall therefore often have a device with which, instead of the unfiltered air from the vehicle exterior, untreated air is supplied from the region of the engine compartment of the internal combustion engine, a so-called secondary intake.
  • the collection of snow in the intake system can for example be done by a snow sieve or grid at a defined location.
  • Through the intake from the engine compartment By the engine waste heat already heated raw air of the engine is supplied by this heated unfiltered air can also be snow, which has already been collected in the intake or in the air filter, eg on the snow sieve, or on the air filter element thawed and as water at a lower outlet from the Intake system be discharged.
  • a solution is known in which the raw air is passed from the vehicle exterior via a pipe in the air filter.
  • the pipe ends with a snow sieve in the air filter housing.
  • a flap that closes with weight or spring loading leads from the engine compartment to the dirty side of the air filter into the air cleaner housing. If snow collects in the snow sieve, the differential pressure between the raw side of the air filter and ambient pressure increases until the flap opens against the spring force or the force of gravity and air from the engine compartment reaches the dirty side of the air filter. Through this heated air, the snow melts in the sieve and so releases the intake to the vehicle exterior again.
  • Such a flap can of course also at risk of contamination or other constipation of the intake from the vehicle exterior be used for internal combustion engine. Flap systems are also from the US 2006/0168920 and the DE 87 15 030 known.
  • the object of the invention is to provide an easy to be integrated into an intake system to switch between Rohluftansaugung from the engine compartment and the vehicle exterior.
  • it is the object to provide a system in which the production of air filters with switching ability and without switching option is cost-effective for the use of a motor vehicle type for different climates possible.
  • an anti-skid module according to claim 1 which can be inserted into an air filter, by an air filter according to claim 5, in which an anti-skid module is inserted through an air filter according to claim 8 in which an anti-skid module is inserted an air filter according to claim 9, with a special embodiment of the closure of an inlet for a secondary intake, solved.
  • An anti-skid module according to the invention for an air filter comprises a support plate, for supporting on the housing of the air filter; a partition plate for mounting inside the housing of the air filter; a valve plate for sealing the housing of the air filter below a predetermined differential pressure between the interior of the housing of the air filter behind the valve plate and the exterior of the housing of the air filter and the opening of the housing of the air filter above a predetermined differential pressure between the interior of the housing of the air filter behind the Valve plate and the exterior of the housing of the air filter; and at least one guide rail on which the valve plate is slidably mounted with at least one guide sleeve.
  • This embodiment of the anti-skid module allows the anti-skid module to be preassembled outside the air filter housing.
  • the sealing point of the valve plate can be placed between the valve plate and the support plate.
  • the one or more guide rails may connect the support plate and the partition plate.
  • the differential pressure at which opens the valve plate can be specified.
  • elastic plastic elements are also conceivable, for example.
  • the anti-skid module can be preassembled by means of plug connections, it can be produced particularly cost-effectively. If the individual components of the anti-snow module can be plugged together in such a way that the valve plate presses against the support plate in the preassembled state and the supporting and separating plates are connected to one another, then the module can be installed without requiring further adjustments, for example on the assembled air filter. the spring tension to be made.
  • the preassembled anti-skid module has no weld or glue joints between the backing plate, guide rails and separator plate. This facilitates the cost-effective and fast assembly.
  • An air filter for a motor vehicle with an em housing with a first inlet for a primary intake of unfiltered air and with a second inlet for a secondary intake of unfiltered air is equipped with guides on the housing of the air filter.
  • These guides can be designed, for example, as a guide with an L-angle profile or a U-profile.
  • An anti-skid module for closing the second inlet in response to the differential pressure between the interior of the housing of the air filter to the second inlet and the exterior of the housing of the air filter in front of the second inlet can be inserted into the guides.
  • a sealing plate may be used in place of the anti-snow module and seal the second inlet.
  • the air filter housing or a part of the air filter housing can be manufactured with an injection molding tool and used for variants with anti-snow system and without anti-snow system.
  • the guides are preferably designed such that the anti-skid module or the sealing plate can be inserted or inserted into the guides.
  • a gluing or welding of the module in the air filter housing is possible.
  • the guides are such that the anti-snow module inserted into the guides is sufficiently secured, it is possible to dispense with adhesive or welded connection between the anti-snow module and the housing of the air filter. This facilitates cost-effective and easy installation of the anti-snow system in the air filter housing. But even with a bond or welding after insertion is facilitated by the pre-positioning further assembly
  • an air filter for a motor vehicle having a housing with a first inlet for a primary intake of raw air and with a second inlet for a secondary intake of raw air with a special anti-skid device.
  • the anti-skid device includes a valve plate for sealing the housing of the air filter below a predetermined differential pressure between the interior of the housing of the air filter at the second inlet and the exterior of the housing of the air filter. Above a predetermined differential pressure between the interior of the housing of the air filter at the second inlet and the exterior of the housing of the air filter opens the valve plate.
  • the valve plate is slidably mounted on one or more guide rails with at least one guide sleeve.
  • Fig. 1 shows a section of the geodetic lower part of the air filter housing with the anti-skid module.
  • Fig. 2 a to d show the anti-snow module as well as various components of the anti-snow module.
  • Fig. 3 shows a view of a variant of the geodesic lower part of the air filter housing.
  • Fig. 1 a section of the geodetic lower part of an air filter housing 10 is shown.
  • An anti-skid module 11 is mounted in the air cleaner housing.
  • the anti-skid module includes a partition plate 14 which separates the lower part of the air cleaner housing into two areas A and B.
  • the partition plate can also be provided with openings which connect the two areas A and B to one another with fluid.
  • Inserted into the partition plate are two guide rails 18, which are fastened to a support plate 15 or made in one piece with the support plate 15.
  • On the guide rails 19 are springs 13 and a valve plate 16 with two guide sleeves 18. The springs 13 press the valve plate 16 against the support plate 15.
  • the valve plate 16 seals in the closed state with a seal 17 against the support plate 15 from.
  • the anti-skid module 11 In operation, without contamination or obstruction of the primary intake from the vehicle exterior, the anti-skid module 11 is closed and the valve plate 16 is pressed by the springs against the support plate 15, thereby passes no or very little air from the engine compartment into the air cleaner housing. Now takes the pressure difference in the primary intake, so the valve plate 16 is pressed by the ambient pressure against the force of the springs 13 and displaced on the guide rails in the air filter 10. As a result, the secondary intake is opened and air now flows from the engine interior into the air filter 10.
  • the air filter element is inserted into the geodesic lower part of the air filter housing 10, so that it comes to rest in the upper area, inter alia on the partition plate 14.
  • the anti-skid module 11 therefore separates the space below the air filter element into the areas A and B with the partition plate 14. In the operating state without blockage or passage reduction of the primary intake, the air filter element is therefore substantially flowed through in the region B. When opening the valve plate 16, the air filter element is flowed through in the area A.
  • the anti-snow module 11 may be preassembled and mounted as a component in the air cleaner housing 10. The assembly can be done by simply plugging. In the embodiment of Fig. 1 the anti-skid module is inserted with the partition plate 14 in guides on the air filter housing 11 and the support plate to other guides on the air filter housing 11. The insertion can be done with or without snap, in the embodiment of Fig. 1 the anti-snow module 11 is merely plugged in. If necessary, the anti-snow module 11 can also be welded or glued to the air filter housing 10. Since the anti-skid module 11 merely separates different regions A and B on the raw side of the air filter 10, or closes them off from the environment, sealing to the outside or to the partition plate 14 is usually unnecessary.
  • Fig. 2a shows a pre-assembled anti-skid module with the support plate with passages.
  • the valve plate 16 is fitted with guide sleeves 18 on guide rails 19 of the support plate 15.
  • Springs 13 press the valve plate 16 already in the preassembled state against the support plate 15.
  • the guide rails 19 are inserted into the partition plate 14.
  • the entire anti-snow module 11 is therefore also pre-assembled and produced only by mating the individual components.
  • the pre-assembled anti-snow module 11 can then be inserted into the air filter housing 10.
  • Figure 2 b shows the valve plate 16 with guide sleeves 18th
  • Figure 2c shows the support plate 15 with guide rails 19.
  • Figure 2d shows the partition plate 14 with plug-in devices 20 for inserting the guide rails 19 of the support plate 15.
  • the valve plate 16, the partition plate 14 and the support plate 15 are preferably made by injection molding.
  • Fig. 3 shows a section of the geodetic lower part of an air filter housing 10 in an alternative embodiment of the Fig. 1 ,
  • a protective cover 21 attached to the output of the secondary intake to the engine compartment. Through the canopy, the opening of the air filter 10 is protected to the engine compartment before by falling down in the engine compartment dirt or dripping water.
  • the strength of the closure of the secondary intake and thus the pressure at which this opens can be adapted to the data of the internal combustion engine.
  • the valve plate 16 opens from a differential pressure of about 50 mbar.
  • the air filter according to the invention can be easily closed at the passage of the air filter 10 to the engine compartment with a sealing plate and operate without the anti-snow module.
  • the sealing plate is inserted into the guides, which can also accommodate the support plate 15.
  • the air filter element is then the entire surface below the air filter element with the rooms A and B available. As a result, a cost-effective production is allowed. Only one tool is necessary for the injection molding of the lower part of the air filter housing 10.
  • the guide rails are always made with.
  • the housing of the air filter 10 is then either closed with a sealing plate or the anti-snow module 11 is inserted into the air filter 10. All components of the anti-snow module 11 are, as they are in the Fig. 1 to 3 are shown easily demoulded from an injection molding tool.
