Definitions

  • the invention relates to an air filter according to the preamble of claim 1.
  • Such an air filter for internal combustion engines, compressors and other air-sucking machines is known from DE-GM 19 60 531.
  • the filter housing of this air filter is flexibly connected to a clean air outlet duct and possibly also to a raw air inlet duct, the filter housing carrying two fork-shaped spring clips which are arranged at a distance from one another. These spring clips can snap into rubber parts that are arranged on the engine housing or on other vehicle parts and thus fix the air filter housing.
  • connection method does not offer sufficient safety for internal combustion engines in vehicles. Especially in land vehicles, greater shocks or bumps are to be expected, which may lead to the spring clips jumping out of the rubber parts. Doing so the air filter may still be held by the connecting lines.
  • the invention has for its object to provide an air filter which is elastically and reliably connected to a mounting flange and is simple in design.
  • a major advantage of the invention is the fact that a vibrating metal element is used as the elastic fastening element, which, however, does not receive the air filter housing with a snap connection, but instead creates a reliable connection between the air filter and the fastening flange by means of a screw connection.
  • the elastic intermediate tube can have a shape that is favorable in terms of flow technology and is completely decoupled from the carrying or supporting function.
  • the invention thus creates a compact connection module which can be pre-assembled as a structural unit and thus enables simple final assembly and also simple replacement.
  • this connection module has a mounting flange. This is directly connected to the intake tract or can be screwed onto a receptacle of the intake tract.
  • the elastic intermediate tube consists of an elastomer and is tied to the fastening flange and / or the air filter housing. This type of connection can be applied to the elastic intermediate tube without any problems, since the actual attachment of the air filter takes place via the vibrating metal elements and there is therefore no danger that this attachment will come loose in the event of strong impacts or vibrations.
  • Another embodiment of the invention provides for the elastic intermediate tube to be provided with an inlet funnel or for an inlet funnel to be arranged on the elastic intermediate tube as an additional part.
  • This additional part can be an aluminum sheet or a plastic molded part. This advantageously improves the flow properties of the air filter.
  • the elastic intermediate tube is convex in the radial direction between the two connection points of the air filter housing and the mounting flange.
  • the air filter according to FIG. 1 consists of a lower housing part 10, a cover 11 and an air filter insert 12 clamped between the lower housing part and cover 11.
  • a raw air inlet 15 is arranged on the lower housing part 10.
  • the cover is fastened to the lower housing part with tension locks 16.
  • On the lower housing part 10 are arranged concentrically to a clean air outlet 17 vibrating metal elements 18, 19.
  • three elements are arranged at an angle of 120 ° to each other.
  • These vibrating metal elements 18, 19 are fixed on the one hand by means of screw connections 20, 21 to the lower housing part and on the other hand by means of screw connections 22, 23 to a fastening flange 24.
  • An elastic intermediate tube 25 is tied in between the opening of the lower housing part 10 at the clean air outlet 17 and the fastening flange 24.
  • This intermediate tube grips at its upper end over the opening of the lower housing part and encloses this opening.
  • the intermediate tube 25 is fixed to the mounting flange 24.
  • the type of attachment is irrelevant.
  • the intermediate tube can, for example, be tied into recesses in the fastening flange. In the figure, this intermediate tube 25 is vulcanized into the fastening flange 24 as an elastomer part.
  • the intermediate tube 25 is provided with a sheet metal apron 26 at the upper end. On the one hand this serves to secure the intermediate pipe, on the other hand it improves the flow behavior of the intake air in this area.
  • the fastening flange 24 is screwed directly onto an injection system 27.
  • the lower housing part 10 forms a compact structural unit with the vibration-damping system of the oscillating metal elements and the elastic intermediate tube, which is designed as a connection module between the air filter and the intake tract.
  • connection module An alternative embodiment of the connection module is shown in FIG. 2, where the intermediate tube 25 and the oscillating metal element 19 are designed as one unit.
  • the fastening flange 24 is vulcanized into the oscillating metal element 19.
  • the vibrating metal element 19 also contains a bore 28 in which a steel plate is inserted.
  • the connection module is connected to the lower housing part of the air filter via a riveted connection in the bore 28.
  • connection module A further variant of the connection module is shown in FIG. 3.
  • the intermediate tube 25 and the oscillating metal element 19 are one unit.
  • a threaded bolt 30 is vulcanized onto the oscillating metal element 19.
  • the lower housing part 10 of the air filter is screwed onto this threaded bolt 30.
  • the vulcanized-on fastening flange 24 is provided with a fastening bore 31 for fastening the entire air filter to the injection system 27, which is shown in FIG. 1.
