。DETAILED DESCRIPTION OF THE INVENTION The present invention provides that the filtered air pipe of a filter case having a filter cartridge made of plastic and separating a filtered air range from an unfiltered air range and a filtered air pipe, It has great strength in the screw tightening range, and the filter (2) ridge is centered and is tightened in the axial direction through the metal connecting piece in the filtered air pipe.
Internal combustion engines, compressors and other air-breathing machines with which there is a gap-tight connection to the filtered air pipe, the filtered air pipe being made of plastic and forming a single workpiece together with the adjacent case parts. relating to intake air filters.

使用状態において最適の強度と密封性を与える。In intake air filters of sheet metal construction, the attachment of the filter cartridge is usually carried out via an axial force-directing coupling piece located in the center of the filter cartridge 1-ridge, and the filter cartridge is attached to the end face of the filter case without any gaps. is being pressed against. This requires a threaded mounting rod,
Usually, it is attached to the end face of the filter case by a welded transverse connecting piece at the filter outlet on the filtered air side. This method of mounting the filter cartridge provides optimum strength and sealing under all conditions of use.

ないからである。If such a filter case were to be made from plastic, in particular thermoplastic, in order to save weight and costs, it turns out that this mounting method is no longer possible in W et al. This is because the mounting elements are so severely deformed by the forces that occur, especially under the influence of heat, that the connection and sealing of the filter cartridge can no longer be guaranteed to the required extent.

まれた。しかし必要な溶接構造のため、特に濾過空気管
が湾曲している場合、この方策は非常に費用がかかる。The problem of providing an air filter made of plastic with a recess on the central screw 1 has hitherto been solved by giving the filter greater strength in the area of the abutment lid screwing of the filter cartridge 1-ridge. Moreover, the abutment lid screwing area of the filter air pipe and the filter car 1-ridge was constructed of a metal plate, which was subsequently embedded in the bottom of the injection-molded filter. However, because of the required welded construction, this solution is very expensive, especially if the filtered air tube is curved.
さらに特に溶接応力が存在すると、プラスチック底部と
後で埋込まれる金属板部分との結合がゆるむおそれがあ
る。Furthermore, especially in the presence of welding stresses, the connection between the plastic base and the later embedded metal plate part may loosen.

タを開発することである。Therefore, it is an object of the present invention to provide a filter car made of plastic, which is made by injection molding technology, has the advantage of having a center thread of the ridge, and which is free from the risk of loosening of the connection due to thermal or mechanical influences (4). The goal is to develop air filters.

成している。According to the present invention, this problem is solved as follows. That is, the filtered air pipe and the abutment area of the filter cartridge are reinforced by a built-in metal plate sleeve containing a connecting piece and having an integral flange extending into the case wall at right angles to the axis, a part of the flange being connected to the filter cartridge. It extends on the surface closer to the cartridge and forms an annular ridge thereon which serves as the abutment surface for the filter cartridge.

にするのが有利である。The forces resulting from the axial tightening of the filter cartridge L-ridge are thereby mostly introduced into this tSfil of the metal plate part, so that the plastic part is significantly relieved of the load due to the cartridge mounting. Since the transition area from the abutment area to the filtered air pipe has a particularly high strength, it is advisable to locate the metal layer in this area. Furthermore, in the area of the flange, a plastic bump is provided as an additional abutment (5) of the filter cartridge concentrically with the bump made of the metal plate, so that the vibrations of the filter cartridge are not affected by the embedded metal plate part. It is advantageous to do so.

金属板スリーブ６に取付けられている。The intake air filter 1 has a bottomed cylindrical filter case 2 with an unfiltered air intake pipe 3, from which a central filtered air pipe 5 emerges from the case bottom 4, which are integrally made of plastic. There is. The filtered air pipe 5 is reinforced by an embedded metal plate sleeve 6, to which the crosspiece 7 carrying the central screw 8 for mounting the filter cartridge 9 is also attached.

る。The sheet metal sleeve 6 has an integral flange 10 extending into the case wall or case bottom 4 at right angles to the axis, a part of which extends on the surface near the filter cartridge 9 and is located there. An annular protuberance 11 is formed on the filter cartridge, which serves as an abutment surface for the filter cartridge. The metal plate sleeve 6 and the flange 10 are made of the well-known (6
) It has a restraint hole 12 and a restraint hole 13 for well restraining the metal plate sleeve 6 to the plastic. The housing bottom 4 is furthermore provided with a plastic ridge 14 in the area of the flange 1°, which ridge 14 provides another abutment surface for the filter car 1-ridge 9 and at the same time reduces vibration stresses on the metal plate sleeve 6 and the flange 10. I am trying not to add any. The filter cartridge 9 is pressed against the contact surfaces 11 and 14 by the necks 1 to 15 and the center screw 8, and the sealing between the unfiltered air side and the filtered air side is performed by the filter cartridge sealing piece 16 made of a soft 8-piece. It will be done. A further sealing arm 18 attached to the filter cartridge body 17 seals the filter case 2 against the outside.

へ取付けることも可能である。When manufacturing the filter case, the plastic is formed around the metal plate parts of the finished cartridge mounting device, which therefore consist of flanges, sleeves, crosspieces and central screws. However, it is also possible to later attach the central screw to the crosspiece.

ルタは特に簡単かつ安価に製造することができる。The advantages obtained by the invention are inter alia the following: That is, the forces that occur when installing the filter car 1-ridge are absorbed by the metal plate sleeve and the metal plate flange and therefore do not load the joint between the plastic and the metal plate part, but rather strengthen the connection between the plastic and the metal plate. It helps make sure. Furthermore, this new filter can be manufactured particularly easily and inexpensively.
