Thermoplastic material are partitions on the resonator tube and on the radial outer diameter the partition walls sealing lips arranged.
the partitions and The outside sealing lips are different resonator chambers in the receptacle sealed off from each other.
the partitions also serve for sealing the resonator chambers outwards or inwards into the installation space of the filter housing. Accordingly, the partitions with the sealing lips adapted to the inner shape of the receptacle to create the seal there to be able to.
the flexible sealing lips are based on the 2-component process molded partitions.
the air filter includes that the resonator tube is non-destructive is detachably arranged in the filter housing.
the resonator tube can be retrofitted in the intake port of an air filter housing can and is connected to this via a detachable connection.
the detachable connection is conceivable as a screw connection or clip connection or other in the stand the types of connection known in the art.
the configuration of the Resonatorrohres in connection with the receptacle a two-chamber resonator.
this second partition are in turn circular recesses over the circumference arranged, which of a last, essentially surrounding the resonator tube circular partition with sealing lips molded onto the outer area becomes.
the recesses are freely selectable, which is advantageous Design, however, as an annular recess, since this increases the tool costs reduce.
the geometry of the recess has no significant influence on the quality of sound absorption.
the geometry of the partitions with that in the outer The area of the molded sealing lip must be adapted to the geometry of the socket be so as to seal the chambers from each other and from the outside to realize. So there are two resonator chambers in connection with at least part of the receptacle, which by a different Wall thickness of the resonator tube and a different volume of the resonator chamber can cover different frequency ranges. This allows a wider frequency range lower soundproofing.
the air filter can be integrated with an air filter element adapt to different internal combustion engines, depending on the Requirement profile, a modified resonator tube is used.
This has the advantage that not a complete for every new engine variant or every new vehicle model new filter housing must be constructed, but it can be made with a constant Air filter housing only different by replacing the resonator tube Internal combustion engines or engine variants are covered.
a modular system for the assembly of an air filter proposed for the intake air of internal combustion engines contains an air filter housing consisting of at least two housing parts, whereby at least one housing part has a receptacle for a resonator tube, an in the housing arranged filter element and a corresponding to the receptacle designed resonator tube to form a multi-chamber resonator.
This Modular system with the matching parts has the advantage in different Internal combustion engines with different frequency ranges to be damped to be able to.
the simple structure also includes simple swapping individual air filter components. So z. B. when the noise requirement changes by changing the resonator tube of the air filter to the new requirements be adjusted.
such a modular system also meets the requirement economical production and low expenditure for warehouse logistics.
the resonator tube is via detachable connecting means connected to the receptacle.
the releasable connection means include e.g. B. a screw connection or a clip connection or other im Connection means known in the art.
the method according to the invention for manufacturing the air filter includes manufacturing of the air filter housing in the injection molding process, with at least part of the walls the air filter housing forms a receptacle of a resonator tube. in this connection is determined by the tool geometry at the inlet or outlet of the air filter housing Receptacle formed, which neither impedes the air flow nor the size of the air filter element to be used afterwards.
the so made Air filter housing is sealed between the inlet and outlet with an air filter element provided and can then if necessary in the receptacle with a resonator tube be equipped with a resonator silencer.
the air filter produced in this way can without any restriction either with resonator silencer or without resonator silencer be used. This gives the advantage of cheaper manufacturing, because only one tool has to be used and lower storage costs, because two different air filter housings are not kept in stock have to.
An advantageous embodiment of the method for producing the air filter in particular An internal combustion engine is given in that the partitions of the resonator tube Sealing lips are added, which in the releasable connection of the air filter housing and resonator tube a sealing effect between the resulting Effect resonator chambers and to the environment.
