Abstract
Description
Technisches GebietTechnical area
Die Erfindung betrifft einen Luftfilter, insbesondere für die Ansaugluft einer Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1. Üblicherweise bestehen solche Luftfilter aus einem Luftfiltereinsatz, der in einem Gehäuse angeordnet ist, das mit einem Deckel verschlossen wird. Der Luftfiltereinsatz wird abdichtend in das Gehäuse eingelegt und beide Gehäuseteile, welche üblicherweise aus Kunststoff bestehen miteinander verspannt. Gerade bei Kunststoffgehäuseteilen mussten bisher sehr hohe Spannkräfte aufgewendet werden um die bei Kunststoff gelegentlich unebenen Auflageflächen gegeneinander zu pressen. Dies führte dazu, dass trotz der hohen Verspannkräfte die Abdichtung nicht zuverlässig war und damit Leckluft angesaugt wurde.The The invention relates to an air filter, in particular for the Intake air of an internal combustion engine according to the preamble of the claim 1. Usually, such air filters consist of an air filter element, which is arranged in a housing, with a lid is closed. The air filter insert becomes sealing in the Housing inserted and both housing parts, which is usually Made of plastic braced with each other. Especially with plastic housing parts previously had to be used very high clamping forces around the plastic surfaces occasionally uneven to press against each other. This meant that despite the high clamping forces the seal is not reliable was and thus air leakage was sucked.

Offenbarung der ErfindungDisclosure of the invention
Der Erfindung liegt die Aufgabe zugrunde, einen Luftfiltereinsatz und einen Luftfilter zu schaffen, mit welchem eine zuverlässige Abdichtung des Systems unter Vermeidung hoher Spannkräfte bewirkt wird. Diese Aufgabe wird bei einem gattungsgemäßen Luftfilter durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst.Of the Invention is based on the object, an air filter cartridge and to create an air filter with which a reliable Sealing of the system while avoiding high clamping forces is effected. This object is achieved in a generic Air filter by the distinguishing features of the independent Claim 1 solved.
Der wesentliche Vorteil der Erfindung gemäß dem unabhängigen Anspruch 1 liegt darin, dass ein Luftfiltereinsatz nicht zwischen Deckel und Gehäuse axial verspannt wird sondern dass die Dichtung derart ausgestaltet ist, dass eine radiale Verspannung der Dichtung durch das Zusammenfügen von Deckel und Gehäuse entsteht. Die Dichtung des Luftfiltereinsatzes ist dabei derart geformt, dass sie einerseits eine Dichtfläche aufweist, die von dem Filtermedium abgewandt ist und ferner einer Dichtfläche die dem Filtermedium zugewandt ist. Dadurch entstehen zwei Dichtflächen, die sich umlaufend längs des Filtermediums erstrecken und gleichzeitig parallel zur Strömungsrichtung sich ausdehnen.Of the significant advantage of the invention according to the independent Claim 1 is that an air filter insert is not between Cover and housing is axially braced but that the Seal is designed such that a radial tension of the Seal by the assembly of cover and housing arises. The seal of the air filter cartridge is such shaped so that on the one hand it has a sealing surface, which faces away from the filter medium and also a sealing surface which faces the filter medium. This creates two sealing surfaces, which extend circumferentially along the filter medium and at the same time extend parallel to the flow direction.
Weiterbildungsgemäß ist die Dichtung an dem Filtermedium angeschäumt bspw. eine PUR-Schaumdichtung, die sich teilweise über die Anströmfläche erstreckt und somit für eine zuverlässige Verbindung zwischen Filtermedium und Dichtung sorgt.Training is according to Foamed the seal on the filter medium, for example. A PUR foam seal, partially over the inflow area extends and thus for a reliable connection between filter medium and seal ensures.
Eine weitere Ausgestaltung der Erfindung sieht vor an der ersten Fläche der Dichtung die zum Filtermedium hingerichtet ist eine Nut anzuformen d. h. diese erste Fläche bildet eine Wandung der Nut, während die weitere Wandung der Nut dem Filtermedium zugewandt ist. Diese Nut bildet die Aufnahme für einen Dichtungssteg an einem Gehäuse oder an einem Deckel.A further embodiment of the invention provides on the first surface the seal which is executed to the filter medium to form a groove d. H. this first surface forms a wall of the groove, while the further wall of the groove faces the filter medium. These Groove forms the receptacle for a sealing web at one Housing or on a lid.
Die Dichtung ist konzeptionell gemäß einer Ausgestaltung der Erfindung zungenartig ausgebildet, wobei die Zunge an einer Oberfläche durch ein Gehäuse und an einer anderen Oberfläche durch einen Deckel abgedichtet ist.The Seal is conceptually according to an embodiment of the invention tongue-like, wherein the tongue on a Surface through a housing and another Surface is sealed by a lid.
Die Erfindung betrifft auch einen Luftfilter mit einem Luftfiltereinsatz, wobei der Luftfilter aus einem Gehäuse und einem Deckel besteht, wobei hier unter dem Begriff Gehäuse bzw. Deckel nicht bestimmte konstruktive Bauteile zu verstehen sind sondern sämtliche Komponenten bei denen eine Komponente im Bezug auf die andere Komponente bewegt werden kann um einen Luftfiltereinsatz zwischen den beiden Komponenten anzuordnen. Die beiden Komponenten weisen Dichtflächen auf, die im Zusammenwirken mit den Dichtflächen des Filtereinsatzes eine radiale Abdichtung eines Filtereinsatzes bewirken, wobei hier der Begriff radial derart zu verstehen ist, dass er eine Dichtkraft beschreibt, die im Wesentlichen rechtwinklig zu der Fügerichtung d. h. dem Einbringen eines Luftfilterelements in ein Gehäuse und einem Verschließen des Gehäuses mit einem Deckel zu verstehen ist.The The invention also relates to an air filter with an air filter insert, the air filter consists of a housing and a lid exists, here under the term housing or cover not certain structural components are to be understood but all Components where one component in relation to the other component can be moved around an air filter insert between the two To arrange components. The two components have sealing surfaces on, in cooperation with the sealing surfaces of the filter cartridge a Radial sealing effect of a filter insert, in which case the Term is to be understood radially such that it has a sealing force describes, which is substantially perpendicular to the joining direction d. H. the introduction of an air filter element in a housing and closing the housing with a Cover is to be understood.
