FiIterSystem FiIterSystem

Die Erfindung betrifft ein Filtersystem für ein Kraftfahrzeug, insbesondere ein Luftfilter für ein Nutzfahrzeug, nach dem Oberbegriff des Patentanspruchs 1 sowie des Patentanspruchs 11.The invention relates to a filter system for a motor vehicle, in particular an air filter for a commercial vehicle, according to the preamble of patent claim 1 and of patent claim 11.

Aus der DE 100 32 384 Al ist ein Filtersystem für ein Kraftfahrzeug, insbesondere ein Luftfilter für ein Nutzfahrzeug, bekannt, welches ein Einlassgehäuseteil, durch den zu reinigendes Fluid, insbesondere Rohluft, zuführbar ist, eine Anordnung von mehreren Filterelementen, die zur Schmutzabscheidung von dem zu reinigenden Fluid durchströmbar sind, sowie ein Auslassgehäuseteil, durch den gereinigtes Fluid abführbar ist, aufweist. Das Einlassgehäuseteil weist eine Einlasskammer auf, und die patronenförmig gestalteten Filterelemente sind in der Einlasskammer in einer Reihe hintereinander angeordnet und gemeinsam von dem zu reinigenden Fluid umströmbar.From DE 100 32 384 Al a filter system for a motor vehicle, in particular an air filter for a commercial vehicle, is known, which an inlet housing part, can be fed through the fluid to be cleaned, in particular raw air, an arrangement of a plurality of filter elements, the dirt separation of the through which the fluid to be purified can flow, as well as an outlet housing part through which purified fluid can be discharged. The inlet housing part has an inlet chamber, and the cartridge-shaped filter elements are arranged in the inlet chamber in a row one behind the other and can be flowed around jointly by the fluid to be cleaned.

Aufgabe der Erfindung ist es demgegenüber ein Filtersystem zu schaffen, welches eine einfache und kompakte Bauweise bei gleichzeitiger hoher Reinigungsleistung aufweist und für unterschiedliche Luftmengen von unterschiedlichen Motorvarianten einsetzbar ist. Diese Aufgabe wird durch ein Filtersystem mit den Merkmalen des Patentanspruchs 1 sowie des Patentanspruchs 11 gelöst.The object of the invention is in contrast to provide a filter system which has a simple and compact design with simultaneous high cleaning performance and can be used for different amounts of air of different engine variants. This object is achieved by a filter system having the features of patent claim 1 and patent claim 11.

Das erfindungsgemäße Filtersystem zeichnet sich dadurch aus, dass die Filterelemente axial durchströmbar sind, wobei bei gleichen Fluiddurchsätzen durch die Variation der Anzahl der Filterelemente die Reinigungsleistung des Filtersystems veränderbar ist. Mittels einheitlicher Filterpatronen können somit durch Kombination der Anzahl unterschiedliche Motorleistungen und damit Fluiddurchsätze bedient werden. Dies bedeutet im Weiteren, dass auch mit ein- und demselben Filtergehäuse verschiedene Fluiddurchsätze und damit Motorleistungen abgedeckt werden können und nicht je nach Baureihe des Fahrzeugs das Filtergehäuse entsprechend dem Fluiddurchsatz immer wieder konstruktiv angepasst werden muß. Das erfindungsgemäße Filtersystem ermöglicht vorteilhaft eine axiale Anströmung, Durchströmung und Abströmung der Filterelemente in gleichbleibender Richtung ohne Strömungsumlenkung des zu reinigenden Fluids. Dadurch wird der bei Umströmung der Filterelemente durch die Uinlenkung der Luft auftretende zusätzliche Druckverlust und somit der damit verbundene höhere Kraftstoffverbrauch bzw. eine Leistungsverminderung der Brennkraftmaschine auf zuverlässige Weise weitestgehend vermieden.The filter system according to the invention is characterized in that the filter elements are axially flowed through, wherein at the same fluid flow rates by the variation of the number of filter elements, the cleaning performance of the filter system is variable. By means of uniform filter cartridges can thus be operated by combining the number of different engine performance and thus fluid flow rates. This means, furthermore, that different fluid throughputs and thus engine outputs can be covered even with one and the same filter housing and not depending on the series of the vehicle, the filter housing according to the fluid flow rate must always be adapted constructively. The filter system according to the invention advantageously allows an axial flow, flow and outflow of the filter elements in the same direction without flow deflection of the fluid to be cleaned. As a result, the additional pressure loss occurring during flow around the filter elements as a result of the deflection of the air and thus the associated higher fuel consumption or a power reduction of the internal combustion engine are largely avoided in a reliable manner.

Aufgrund der axialen Anströmung und Abströmung kann der Filter vorteilhafterweise in ein Rohr1eitungsSystem eingesetzt werden. Die Integration des Filtergehäuses in die Roh- oder Reinluftführung erspart das Vorsehen von zusätzlichem Bauraum für das Filtergehäuse. Roh- und/oder Reinluftleitungen können somit zumindest teilweise entfallen. Hierdurch wird das erfindungsgemäße Filtersystem in seiner Bauweise wesentlich einfacher und kompakter und verringert somit die Teilevielfalt und hilft dadurch Kosten in der Fertigung und im Ersatzteilwesen sparen. In einer Ausführungsform nach Anspruch 2 sind die Aufnahmeeinrichtungen in Durchströmungsrichtung parallel zueinander im Filtergehäuse angeordnet.Due to the axial flow and outflow, the filter can be advantageously used in a Rohr1eitungsSystem. The integration of the filter housing in the raw or clean air guide saves the provision of additional space for the filter housing. Raw and / or clean air lines can thus be at least partially eliminated. As a result, the filter system according to the invention in its construction is much simpler and more compact and thus reduces the variety of parts, thereby helping to save costs in manufacturing and spare parts. In an embodiment according to claim 2, the receiving devices are arranged in the flow direction parallel to each other in the filter housing.

In einer weitergebildeten Ausführungsform nach Anspruch 3 sind die Aufnahmeeinrichtungen quer zur Durchströmungsrichtung in einer Ebene im Filtergehäuse angeordnet .In a further developed embodiment according to claim 3, the receiving means are arranged transversely to the flow direction in a plane in the filter housing.

Gemäß einer bevorzugten Ausführungsform nach Anspruch 4 sind die Aufnahmeeinrichtungen in Durchströmungsrichtung zur besseren Fluidverteilung gegeneinander versetzt im Filtergehäuse angeordnet.According to a preferred embodiment according to claim 4, the receiving means are arranged offset in the flow direction for better fluid distribution against each other in the filter housing.

Bei einem nach Anspruch 5 ausgeführten Filtersystem ist die äußere Form des Filtergehäuses an die Platzverhältnisse des Kraftfahrzeuges angepasst.In a running according to claim 5 filter system, the outer shape of the filter housing is adapted to the space conditions of the motor vehicle.

In einer Ausführungsform nach Anspruch 6 weist mindestens eine Aufnahmevorrichtung kein Filterelement auf.In an embodiment according to claim 6, at least one receiving device has no filter element.

In einer vorteilhaften Weiterbildung der Erfindung nach Anspruch 7 ist die nicht belegte Aufnahmeeinrichtung mit einem Dichtmaterial verschlossen. Dies kann beipielsweise ein Deckel oder eine Abdeckplatte mit zusätzlicher Abdichtung gegen die Umgebung sein, damit sich Roh- und Reinluftbereich nicht vermischen können.In an advantageous development of the invention according to claim 7, the unoccupied receiving device is closed with a sealing material. This can be, for example, a cover or a cover plate with additional seal against the environment, so that raw and clean air area can not mix.

In einer besonders vorteilhaften Weiterbildung nach Anspruch 8 ist der durch das mindestens eine fehlende Filterelement entstandene Leerraum als Resonanzvolumen nutzbar. In einer alternativen Ausführungsform nach Anspruch 9 sind die Filterelemente als Patronen ausgebildet. Die Patrone ist beispielsweise durch gewickeltes oder geschichtetes Filterpapier bevorzugt als zylinderförmiger, quaderförmiger, prismenförmiger oder ovaler Körper herstellbar. Durch eine entsprechende Vergrößerung der Anströmfläche der Patronen lässt sich der Druckverlust der jeweiligen Patronen gezielt verringern. Als Filtermedien können an sich bekannte Papierfilter, Vliese, sowie auch mehrkomponentige und/oder mehrschichtige Materialien eingesetzt werden.In a particularly advantageous development according to claim 8, the space created by the at least one missing filter element can be used as resonance volume. In an alternative embodiment according to claim 9, the filter elements are designed as cartridges. The cartridge can be produced, for example, by wound or layered filter paper, preferably as a cylindrical, cuboidal, prismatic or oval body. By a corresponding increase in the inflow area of the cartridges, the pressure loss of the respective cartridges can be specifically reduced. As filter media known per se paper filter, nonwovens, as well as multi-component and / or multi-layer materials can be used.

Gemäß einer nach Anspruch 10 ausgeführten Erfindung sind die Filterelemente steckbar.According to an embodiment of the invention, the filter elements are pluggable.

Gemäß Anspruch 11 ist das Filtergehäuse des erfindungsgemäßen Fahrzeugs im Bereich eines Radkastens angeordnet.According to claim 11, the filter housing of the vehicle according to the invention is arranged in the region of a wheel house.

In einer weiteren bevorzugten Ausführungsform nach Anspruch 12 ist das Filtergehäuse in seiner Form dem Radkasten angepasst. Das Filtergehäuse ist durch die flexible Anordnung der einzelnen Patronen prinzipiell an jeglichen Bauraum anpassbar.In a further preferred embodiment according to claim 12, the filter housing is adapted in shape to the wheel arch. The filter housing is in principle adaptable to any space due to the flexible arrangement of the individual cartridges.

Bei einer bevorzugten Weiterbildung nach Anspruch 13 ist die Einlassöffnung und damit der Rohlufteintritt mit einem Ende einer Rohrleitung verbunden, deren anderes Ende im Bodenbereich, im Dachbereich (17) des Fahrzeugs oder in einem Bereich zwischen (Fahrbahn) Boden und Dach endet.In a preferred embodiment according to claim 13, the inlet opening and thus the Rohlufteintritt is connected to one end of a pipe whose other end in the floor area, in the roof area (17) of the vehicle or in an area between (road) floor and roof ends.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Filtersystems sowie des erfindungsgemäßen Fahrzeugs sind Gegenstand der Unteransprüche und der Beschreibung. Die Erfindung wird nun anhand der beigefügten Zeichnungen weiter beschrieben. In dieser zeigt beispielhaft auf schematische Weise:Advantageous embodiments of the filter system according to the invention and of the vehicle according to the invention are the subject matter of the subclaims and the description.

Ferner weisen die in den Fig. 1 bis 6 dargestellten erfindungsgemäßen FiIterSysteme zwischen Filtergehäuse 1 und nicht gesondert dargestelltem Deckel zur Abdichtung gegen die Umgebungsluft eine weitere Dichtung auf. Als Materialien zur Abdichtung kommen beispielsweise Dichtschnüre aus elastischen Werkstoffen, wie z.B. PUR-Kautschuke oder andere geeignete Materialien, zur Anwendung.The filter system according to the invention shown in Fig. 1 shows a filter housing 1 with an inlet opening 2 for the fluid to be cleaned, preferably the unfiltered air, and a Outlet opening 3 for the purified fluid, preferably the clean air, with subsequent clean air line 3.1. The outlet opening 3 may preferably be formed into a pipe socket for connection to the clean air line 3.1. The filter system is integrated here in the region of the raw air line, so that conveniently costly raw air lines can be omitted and thus can be saved as a further advantage space. The interior of the filter housing 1 has two receiving devices not shown in detail for receiving a respective filter element 4, wherein the receiving devices and thus the filter elements 4 are arranged in the flow direction parallel to each other in the filter housing 1. However, more than two receiving devices for receiving one filter element 4 may be provided without further ado. The filter elements 4 are advantageously designed as cartridges 8 here. Not separately shown seals in the interior of the filter housing 1, which are attached to the cartridges 8, the filter housing 1 and / or on the receiving devices or other suitable locations preferably by gluing, molding or foaming and act radially or axially, separate within the filter housing 1 the Raw air from the clean air area. Furthermore, the filter systems according to the invention shown in FIGS. 1 to 6 have a further seal between the filter housing 1 and the lid (not shown separately) for sealing against the ambient air. Sealing cords made of elastic materials, such as PUR rubbers or other suitable materials, for example, are used as sealing materials.

Je nach Motorvariante oder Luftbedarf kann aufgrund des jeweiligen Einsatzes (On- oder Off-Road) die zur Filterung benötigte Filterfläche durch Hinzufügen oder Weglassen von Filterpatronen angepasst werden. Die Reinigungsleistung des Filtersystems ist durch die Variation in Bezug auf die Anzahl und/oder die Kapazität zur Aufnahme von Schmutzpartikeln der Patronen beliebig variierbar. Der Fluiddurchsatz ist abhängig von der Motorleistung; die Patronen 8 werden auf den von der Brennkraftmaschine benötigten (Luft) Durchsatz entsprechend ausgelegt.Depending on the engine variant or air requirement, due to the particular application (on- or off-road), the filter surface required for filtering can be added by omitting or omitting Filter cartridges are adjusted. The cleaning performance of the filter system is arbitrarily variable by the variation with respect to the number and / or the capacity for receiving dirt particles of the cartridges. The fluid flow depends on the engine power; the cartridges 8 are designed according to the (air) throughput required by the internal combustion engine.

Die Pfeile symbolisieren die Strömungsrichtung des zu reinigenden Fluids, hier der angesaugten Verbrennungsluft für die Brennkraftmaschine. Das zu reinigende Fluid, die Rohluft, wird dem Filtersystem an dessen Anströmseite zugeführt, wobei die Filterelemente 4 axial durchströmt werden. Das gereinigte Fluid, die Reinluft, verlässt das Filtersystem über dessen Abströmseite, wobei die Filterelemente 4 in den Aufnahmeeinrichtungen quer zur Durchströmungsrichtung in einer Ebene im Filtergehäuse 1 angeordnet sind.The arrows symbolize the flow direction of the fluid to be cleaned, here the sucked combustion air for the internal combustion engine. The fluid to be cleaned, the raw air is fed to the filter system on the inflow side, wherein the filter elements 4 are flowed through axially. The cleaned fluid, the clean air, leaves the filter system via its outflow side, wherein the filter elements 4 are arranged in the receiving means transversely to the flow direction in a plane in the filter housing 1.

Die Filterelemente 4 sind auf einfache Art und Weise in die dafür vorgesehenen Aufnahmevorrichtungen innerhalb des Filtergehäuses 1 steckbar. Hierzu muss das Filtergehäuse 1 eine entsprechende Aufnahmevorrichtung bzw. Führung (nicht gezeigt) aufweisen. Ein Verdrehen oder Verrutschen der Patronen wird durch Formschluss mit dem Filtergehäuse 1 und seiner Aufnahmevorrichtung bzw. Führung zuverlässig verhindert. Mit der Verspannung in axialer oder radialer Richtung, welches von der verwendeten Dichtvariante abhängt, erfolgt die endgültige Positionierung der Patronen 8. Dies erfolgt durch den nicht gesondert dargestellten Filtergehäusedeckel bzw. die Filtergehäuseabdeckung, welcher nach seiner Entfernung eine Öffnung zur Wartung der Patronen 4 freigibt. Die Patronen 8 sind somit ebenso einfach im Rahmen einer Wartung oder im Falle eines Ersatzes wieder entnehmbar. Die Entnahme der auswechselbaren Filterelemente 4 kann roh- oder reinluftseitig erfolgen. Da bei der Entnahme des auswechselbaren Filtereinsatzes 4 Verunreinigungen in das Filtergehäuse 1 gelangen und dadurch die nachfolgenden Systeme schädigen können, kann im Anschluss an die Filterelemente 4 ein Sekundärelement 4.2 zur Zurückhaltung von diesen Verunreinigungen vorgesehen sein. Zur Abscheidung von groben Verunreinigungen kann den Filterelementen 4 ferner ein Vorfilter 4.1, wie z.B. eine gitterartige Struktur aus Metall oder Kunststoff, ein Vlies, Zyklone oder ein ähnlich geeignetes Mittel zur Vorfilterung, vorgeschaltet sein. Beide Vorfilter 4.1 und Sekundärelement 4.2 können in das Filtergehäuse 1 integriert sein.The filter elements 4 can be plugged in a simple manner into the receiving devices provided within the filter housing 1. For this purpose, the filter housing 1 must have a corresponding receiving device or guide (not shown). A twisting or slipping of the cartridges is reliably prevented by positive engagement with the filter housing 1 and its receiving device or guide. With the tension in the axial or radial direction, which depends on the sealing variant used, the final positioning of the cartridges 8. This is done by the filter housing cover not shown or the filter housing cover which releases an opening for the maintenance of the cartridge 4 after its removal. The cartridges 8 are therefore just as easy to remove as part of a maintenance or in the event of replacement. The removal of the interchangeable filter elements. 4 can be done raw or clean air side. Since impurities can enter the filter housing 1 when the interchangeable filter insert 4 is removed, thereby damaging the subsequent systems, a secondary element 4.2 can be provided following the filter elements 4 for restraining these contaminants. For the deposition of coarse impurities, the filter elements 4 may further be preceded by a pre-filter 4.1, such as a grid-like structure made of metal or plastic, a fleece, cyclones or a similarly suitable pre-filtering means. Both pre-filter 4.1 and secondary element 4.2 may be integrated into the filter housing 1.

Bei Nichtbelegung der vorhandenen Aufnahme- oder Steckvorrichtungen ist der durch das mindestens eine fehlende Filterelement 4 entstandene Leerraum vorteilhafter Weise als Resonanzvolumen nutzbar.If the existing receiving or plug-in devices are not used, the empty space created by the at least one missing filter element 4 can be used advantageously as a resonance volume.

Fig. 2 zeigt eine Variante des Filtersystems von Fig. 1, wobei der Übersichtlichkeit halber für funktionell gleiche oder gleichwirkende Komponenten dieselben Bezugszeichen verwendet werden und insoweit auf die obige Beschreibung zu Fig. 1 verwiesen werden kann.FIG. 2 shows a variant of the filter system of FIG. 1, wherein for the sake of clarity, the same reference numerals are used for functionally identical or equivalent components and, to that extent, reference can be made to the above description of FIG.

In Fig. 2 weist das Filtergehäuse 1 drei nicht gesondert dargestellte Aufnahmeeinrichtungen auf, welche in Durchströmungsrichtung gegeneinander versetzt im Filtergehäuse 1 angeordnet sind. Aufgrund der versetzten Anordnung ergeben sich im Filtergehäuse 1 ein gemeinsamer Sammelraum 5 auf der Einlassseite (Rohluft) und ein gemeinsamer Sammelraum 6 auf der Auslassseite (Reinluft) der Luftführung. Die Strömungsrichtung ist durch die entsprechenden Pfeile gekennzeichnet. Der Strömungsquerschnitt wird im Sammelraum 5 auf der Einlass- bzw. Rohluftseite in Strömungsrichtung kleiner, damit die Beaufschlagung, d.h. die gleichmäßige Verteilung des Fluids, bei allen Filterpatronen gleich ist. Diese gleichmäßige Anströmung der Filterelemente 4 verhindert lokale Überbelastungen durch abgeschiedene Partikel. Zusätzlich können hier auch Leitvorrichtungen, wie z.B. Schaufeln, Rippen oder ähnliches, vorgesehen sein, welche die Strömung ebenfalls gleichmäßig verteilen.In Fig. 2, the filter housing 1 has three receiving means not shown separately, which are arranged offset in the flow direction against each other in the filter housing 1. Due to the staggered arrangement arise in the filter housing 1, a common plenum 5 on the inlet side (raw air) and a common plenum 6 on the outlet side (clean air) of the air duct. The direction of flow is indicated by the corresponding arrows. The flow cross section is located in the collecting space 5 on the inlet or Rohluftseite smaller in the flow direction, so that the loading, ie the uniform distribution of the fluid is the same for all filter cartridges. This uniform flow of the filter elements 4 prevents local overloading by separated particles. In addition, here also guide devices, such as blades, ribs or the like, can be provided, which also distribute the flow evenly.

Die Roh- und/oder Reinluftrohrführungen können durch die Sammelräume 5,6 weitestgehend ersetzt und so in das Filtergehäuse 1 integriert werden, dass auf diese im wesentlichen verzichtet werden kann. Die Bauweise eines solchen Filtersystems wird daher als ein weiterer Vorteil wesentlich kompakter und benötigt entsprechend weniger Bauraum. Die äußere Form des Filtergehäuses 1 kann somit an die Platzverhältnisse des jeweiligen Kraftfahrzeuges angeglichen werden. Zusätzlich können in den Ausführungsformen der Fig. 1 und 2 Verrippungen zur Steifigkeit des Filtergehäuses und zur Strömungsbeeinflussung beitragen.The raw and / or clean air pipe guides can be largely replaced by the collecting chambers 5,6 and integrated into the filter housing 1, that can be dispensed with this substantially. The design of such a filter system is therefore much more compact as a further advantage and requires correspondingly less space. The outer shape of the filter housing 1 can thus be adapted to the space conditions of the respective motor vehicle. Additionally, in the embodiments of FIGS. 1 and 2, ribs may contribute to the stiffness of the filter housing and to the flow control.

Ferner kann als ein weiterer Vorteil ein einheitliches Filtergehäuse 1 an die jeweilige Motorleistung und den damit verbundenen Luftdurchsatz angepasst werden, indem die erforderliche Filterfläche durch flexible Bestückung des Filtergehäuses 1 mit patronenförmigen Filterelementen 4,8 erfolgt. Dies geschieht durch Variation in Bezug auf Art und/oder Anzahl der jeweils benötigten Filterelemente 4,8. Werden jedoch nicht alle Aufnahmevorrichtungen mit Filterelementen 4 belegt, so wird der entstandene Leerraum im Ein- und Auslassbereich der Aufnahmevorrichtung mit einem Dichtmaterial verschlossen, wie z.B. mit einem Deckel mit Dichtung, damit die angesaugte Rohluft nicht ungefiltert in die Reinluftleitung strömen kann. Vorteilhafterweise ist jedoch der durch das mindestens eine fehlende Filterelement entstandene Leerraum als Resonanzvolumen nutzbar. Hierbei wird die nicht bestückte Aufnahmevorrichtung im Filtergehäuse 1 mit einem Dämfungseinsatz versehen. Durch die Integration eines Schalldämpfers in das Luftfiltergehäuse wird somit eine wesentliche Geräuschdämpfung im Bereich der Luftansaugung erzielt. Dies kann beispielsweise mittels eines Helmholtz- Resonators erfolgen. Es handelt sich um ein zusätzliches Resonanzvolumen, welches zum Reinluftbereich hin geöffnet ist. Dadurch können Pulsationsspitzen gedämpft werden. Das Resonanzvolumen muss in seiner Größe mit den Störfrequenzen abgestimmt werden. Der Resonator kann an jeder nicht bestückten Aufnahmevorrichtung montiert werden.Furthermore, as a further advantage, a unitary filter housing 1 can be adapted to the respective engine power and the associated air throughput by the required filter surface by flexible placement of the filter housing 1 with cartridge-shaped filter elements 4,8. This is done by variation with respect to type and / or number of each required filter elements 4.8. However, if not all recording devices occupied with filter elements 4, the resulting void in the inlet and outlet of the receiving device is sealed with a sealing material, such as a lid with seal, so that the sucked raw air can not flow unfiltered into the clean air line. Advantageously, however, is the through the at least one missing filter element resulting empty space usable as resonant volume. Here, the unequaled receiving device is provided in the filter housing 1 with a Dämfungseinsatz. The integration of a silencer in the air filter housing thus a significant noise attenuation in the air intake is achieved. This can be done for example by means of a Helmholtz resonator. It is an additional resonance volume, which is open to the clean air area. As a result, pulsation peaks can be damped. The resonance volume must be tuned in its size with the interference frequencies. The resonator can be mounted on any unequipped recording device.

Figur 3 zeigt eine mögliche Lage des erfindungsgemäßen Filtersystems im Bereich der Frontluftansaugung. Das Filtergehäuse 1 kann beispielsweise am Fahrzeugrahmen, am Fahrerhaus oder direkt auf der Brennkraftmaschine befestigt sein. Der Luftfilter 7 ist in Fig. 3 direkt vor der Brennkraftmaschine oberhalb des Ladeluftkühlers 9 angeordnet. Das Filtergehäuse 1 ersetzt die Rohluftleitung oder ist Teil der Rohluftleitung. Hierdurch entfällt in vorteilhafter Weise mindestens teilweise eine separate Rohluftleitung. Die Einlassöffnung 2 zur Ansaugung von Rohluft befindet sich oberhalb des Kondensators 9.1. Die Ansaugung der benötigten Luft erfolgt, wie in Fig. 6 dargestellt, aus einer beruhigten Zone zwischen Stirnwand 23 und Brüstung 24 im Bereich des Fahrerhauses 18 heraus. Zusätzlich kann eine Leitung (nicht dargestellt) als Rohluftführung angesetzt sein, um die Ansaugöffnung weiter nach oben zu bringen.FIG. 3 shows a possible position of the filter system according to the invention in the area of the front air intake. The filter housing 1 may for example be attached to the vehicle frame, on the cab or directly on the internal combustion engine. The air filter 7 is arranged in Fig. 3 directly in front of the internal combustion engine above the charge air cooler 9. The filter housing 1 replaces the raw air line or is part of the raw air line. This eliminates advantageously at least partially a separate raw air line. The inlet opening 2 for intake of raw air is located above the condenser 9.1. The suction of the required air takes place, as shown in Fig. 6, from a calm zone between the end wall 23 and parapet 24 in the area of the cab 18 out. In addition, a line (not shown) can be set as Rohluftführung to bring the intake further up.

Die im Filtergehäuse 1 aufgenommenen Filterelemente 4 in Form von Patronen 8 sind als separates Bauteil ausgeführt und werden axial in Richtung des eingezeichneten Pfeiles von der Luft durchströmt. Die Filterelemente 4,8 sind, wie auch in Fig. 1 gezeigt, in Durchströmungsrichtung parallel zueinander und quer zur Durchströmungsrichtung in einer Ebene im Filtergehäuse 1 angeordnet. Die zu reinigende Rohluft wird dem Luftfilter 7 axial an dessen Anströmseite 10 zugeführt, die gereinigte Reinluft verlässt den Luftfilter 7 ebenfalls axial über dessen Abströmseite 11. Die den Luftfilter 7 verlassende Reinluft wird von der Reinluftleitung 12 aufgenommen und wird vorzugsweise zur Aufladung in den Abgasturbolader 13 geführt.The recorded in the filter housing 1 filter elements 4 in the form of cartridges 8 are designed as a separate component and are flowed through axially in the direction of the arrow by the air. The filter elements 4,8 are, as shown in Fig. 1, in the flow direction parallel to each other and arranged transversely to the flow direction in a plane in the filter housing 1. The clean air to be cleaned air is supplied to the air filter 7 axially on the inflow side 10, the purified clean air leaves the air filter 7 also axially on the downstream side 11. The air filter 7 leaving clean air is received by the clean air line 12 and is preferably for charging in the exhaust gas turbocharger 13th guided.

Fig. 4 und Fig. 5 zeigen eine mögliche Lage des erfindungsgemäßen Filtersystems im Bereich der Heckluftansaugung. Bei Nutzfahrzeugen kann das Filtergehäuse 1 mit den darin befindlichen patronenförmigen, nicht näher gezeigten Filterelementen beispielsweise vor dem Vorderrad (nicht gesondert gezeigt) oder im Bereich des Radkasten 15 angeordnet sein, wobei das Filtergehäuse 1 vorzugsweise in seiner Form dem Radkasten 15 angepasst ist. Diese Anpassung wird durch die spezielle Anordnung der Filterelemente im Filtergehäuse 1 ermöglicht, in dem diese in4 and 5 show a possible position of the filter system according to the invention in the area of the rear air intake. In commercial vehicles, the filter housing 1 with the therein cartridge-shaped, not shown filter elements, for example, in front of the front wheel (not shown separately) or in the region of the wheel arch 15 may be arranged, wherein the filter housing 1 is preferably adapted in its shape to the wheel arch 15. This adaptation is made possible by the special arrangement of the filter elements in the filter housing 1, in which this in

Durchströmungsrichtung gegeneinander versetzt, aber parallel zueinander im Filtergehäuse 1 angeordnet sind, ähnlich wie auch in Fig. 2 dargestellt. Hierbei ist aufgrund der flexiblen Anordnung der patronenförmigen Filterelemente 4,8, eine Anpassung des Filtergehäuses 1 an die unterschiedlichsten Bauräume im Fahrzeug in vorteilhafter Weise möglich. Die Strömungsrichtung ist auch hier durch die entsprechenden Pfeile gekennzeichnet: Die zu reinigende Rohluft wird über die Einlassöffnung 2 angesaugt und verlässt nach Filterung über die Auslassöffnung 3 das Filtergehäuse 1 als Reinluft in Richtung Abgasturbolader (nicht gesondert dargestellt) .Flow direction offset from each other, but are arranged parallel to each other in the filter housing 1, similarly as shown in Fig. 2. In this case, due to the flexible arrangement of the cartridge-shaped filter elements 4.8, an adaptation of the filter housing 1 to a variety of installation spaces in the vehicle in an advantageous manner possible. The flow direction is also characterized by the corresponding arrows: The raw air to be cleaned is sucked in via the inlet opening 2 and, after filtering through the outlet opening 3, leaves the filter housing 1 as clean air in the direction of the exhaust-gas turbocharger (not shown separately).

Wie in Fig. 5 gezeigt, ist die Einlassöffnung 2 mit einem Ende 21 einer Rohrleitung 19, hier als Rohluftleitung 19 bezeichnet, verbunden, dessen anderes Ende 16 im Dachbereich 17 des Fahrzeugs endet. Die Ansaugung der Rohluft über die Ansaugstelle 16 ist besonders bei Nutzfahrzeugen, insbesondere bei Baustellenfahrzeugen, über dem Dach 17 des Fahrerhauses 18 wegen des geringeren Staubeintrags bevorzugt. Vorzugsweise verläuft die Rohluftleitung 19 entlang der Fahrerhausrückwand 20 nach unten und mündet anschließend in die Einlassöffnung 2 des Filtergehäuses 1. Der Übergang zwischen Rohrleitung, hier Rohluftführung 19, in das Filtergehäuse 1 wird durch einen Faltenbalg 22 realisiert, der sich zwischen Einlassöffnung 2 und Rohrleitungsende 21 befindet. Durch die unmittelbare Nähe zur Kippachse des Fahrzeugs muss die Luftführung in diesem Bereich nicht getrennt werden; der Balg 22 wird lediglich gedehnt.As shown in FIG. 5, the inlet opening 2 is provided with one end 21 of a pipeline 19, here as a blank air line 19 designated, connected, the other end 16 ends in the roof area 17 of the vehicle. The intake of unfiltered air via the suction point 16 is particularly preferred in commercial vehicles, especially in construction vehicles, above the roof 17 of the cab 18 because of the lower dust input. Preferably, the unfiltered air line 19 extends down the cab rear wall 20 and then opens into the inlet opening 2 of the filter housing 1. The transition between the pipe, here unfiltered air guide 19, in the filter housing 1 is realized by a bellows 22 extending between the inlet opening 2 and the pipe end 21st located. Due to the close proximity to the vehicle's tipping axle, the air flow in this area need not be separated; the bellows 22 is merely stretched.

Die in Fig. 1 bis 6 gezeigten erfindungsgemäßen Filtersysteme benötigen aufgrund der axialen An-, Durch- und Abströmung günstigerweise keine Luftberuhigungskammer im Bereich der Anströmseite 10 der Filterelemente 4,8. The filter systems according to the invention shown in FIGS. 1 to 6 desirably do not require an air calming chamber in the area of the inflow side 10 of the filter elements 4, 8 due to the axial inflow, outflow and outflow.
