Vom Luftfiltergehäuse 2 und 4 führen jeweils zwei Rohrverbindungen 10 und 12 zu einem motorseitig an der Sauganlage befestigten Drosselklappengehäuse 14. Zwischen den beiden Luftfiltern 2 und 4 und dem Drosselklappengehäuse 14 sind zwei Abgasturbolader 13 und 15 angeordnet, deren erzeugte Ladeluft durch zwei nachgeschaltete Luftkühler 16 und 18 gekühlt wird.The suction device shown schematically in Fig. 1 for a two-row Internal combustion engine with turbocharging, for example V8 turbo engine, consists of one each leading to an air filter housing 2 and 4 air line, which as Air manifold tube 6 and 8 is formed. Lead from the air filter housing 2 and 4, respectively two pipe connections 10 and 12 attached to the engine on the intake system Throttle body 14. Between the two air filters 2 and 4 and the Throttle body 14, two exhaust gas turbochargers 13 and 15 are arranged, the generated charge air is cooled by two downstream air coolers 16 and 18.

Zur Befestigung des Luftkrümmerrohres 6, 8 am Luftfiltergehäuse 2, 4 ist im Luftfiltergehäuse 2, 4 eine Öffnung 20 vorgesehen, die von einem Ringkragen 22 begrenzt ist. Am Ringkragen 22 sind als Aufnahmeelemente für zwei Verriegelungsstifte 24 und 26 zwei obere Lageraugen 28a und 28b sowie zwei untere Lageraugen 30a und 30b vorgesehen. Das Luftkrümmerrohr 6, 8 weist einen Flanschabschnitt 32 auf, der im montierten Zustand in den Ringkragen 22 der Öffnung 20 des Luftfiltergehäuses 2, 4 eingreift. Zur Abdichtung beider Bauteile weist der Flanschabschnitt 32 eine radial umlaufende Nut 34 auf, in die ein nicht dargestellter O - Ring eingelegt ist. An den Flanschabschnitt 32 angrenzend sind zwei seitlich angeordnete Lagerhülsen 36 (nur eine sichtbar dargestellt) vorgesehen, die im montierten Zustand beider Bauteile - Luftkrümmerrohr 6, 8 und Luftfiltergehäuse 2, 4 - von den beiden Verriegelungsstiften 24, 26 durchdrungen sind. Die beiden Lagerhülsen 36 weisen jeweils zwei schräg verlaufende Stirnseiten 40 und 42 auf, die im montierten Zustand an der Innenwand des Ringkragens 22 zum Anliegen kommen. Der Ringkragen 22 ist mit jeweils zwei Ausnehmungen 44 und 46 versehen, die als Anschlag für zwei seitlich über den Flanschabschnitt 32 hinausstehende Sperrzapfen 48 (nur einer sichtbar dargestellt) dienen. Damit wird die Einstecktiefe des Luftkrümmerrohres 6, 8 in die Öffnung 20 des Luftfiltergehäuses 2, 4 so begrenzt, dass der Flanschabschnitt 32 vollständig im Ringkragen 22 Aufnahme findet. Der Anschlag über die Sperrzapfen 48 ist so abgestimmt, dass die in den jeweils oberen und unteren Lageraugen 28a und 30a bzw. 28b und 30b vorgesehenen Öffnungen mit den in den beiden Lagerhülsen 36 vorgesehenen Öffnungen korrespondieren bzw. zueinander fluchten. Damit können die zur Befestigung der Luftkrümmerrohre 6, 8 am Luftfiltergehäuse 2, 4 dienenden Verriegelungsstifte 24 und 26 durch die Lageraugen 28 und 30 und die Lagerhülsen 36 hindurch gesteckt werden.To attach the air manifold tube 6, 8 to the air filter housing 2, 4 is in Air filter housing 2, 4 an opening 20 is provided, which by an annular collar 22nd is limited. On the collar 22 are as receiving elements for two locking pins 24 and 26 two upper bearing eyes 28a and 28b and two lower bearing eyes 30a and 30b provided. The air manifold tube 6, 8 has a flange portion 32 which in the assembled state in the annular collar 22 of the opening 20 of the air filter housing 2, 4 intervenes. To seal both components, the flange section 32 has a radial circumferential groove 34 into which an O-ring, not shown, is inserted. To the Flange section 32 is adjacent to two laterally arranged bearing sleeves 36 (only one shown visibly) provided that both components are assembled - Air manifold pipe 6, 8 and air filter housing 2, 4 - from the two locking pins 24, 26 are penetrated. The two bearing sleeves 36 each have two inclines running end faces 40 and 42, which in the assembled state on the inner wall of the Ring collar 22 come to mind. The ring collar 22 is two each Recesses 44 and 46 provided as a stop for two laterally over the Flange section 32 protruding locking pin 48 (only one visible) serve. So that the insertion depth of the air manifold tube 6, 8 in the opening 20 of the Air filter housing 2, 4 limited so that the flange portion 32 completely in the Ring collar 22 takes place. The stop on the locking pin 48 is so coordinated that the in the upper and lower bearing eyes 28a and 30a or 28b and 30b provided openings with the in the two bearing sleeves 36th provided openings correspond or are aligned. So that for attaching the air elbow pipes 6, 8 to the air filter housing 2, 4 serving Locking pins 24 and 26 through the bearing eyes 28 and 30 and the bearing sleeves 36 be put through.

Die Verriegelungsstifte 24 und 26 weisen an ihrem Ende jeweils eine Rastnase 52 und 54 auf, die wie nachfolgend noch näher beschrieben, zur Verriegelung der Befestigung dienen. Damit die mit der Rastnase 52, 54 versehenen Verriegelungsstifte 24, 26 durch die in den oberen und unteren Lageraugen 28a und 30a bzw. 28b und 30b sowie in den Lagerhülsen 36 vorgesehenen Öffnungen hindurch gesteckt werden können, weisen die genannten Bauteile jeweils eine Innennut 56 auf, mit deren Hilfe die mit der Rastnase 52, 54 versehenen Verriegelungsstifte 24, 26 durch die Öffnungen hindurch gesteckt werden können. Wenn die beiden Verriegelungsstifte 24, 26 durch die Öffnungen hindurch gesteckt worden sind, werden die beiden Verriegelungsstifte 24, 26 um jeweils 180° gedreht, wodurch die Rastnasen 52, 54 in jeweils eine an den unteren Lageraugen 30a, 30b vorgesehene Rastnut 58 und 60 zum Eingriff kommen. Damit die Rastnasen 52, 54 sicher in den beiden Rastnuten 58, 60 gehalten werden, sind zwischen den beiden Köpfen 24a und 26a der Verriegelungsstifte 24, 26 und den oberen Lageraugen 28a und 28b jeweils ein Elastomerring 62 und 64 vorgesehen. Der Elastomerring 62, 64 kann bei der Überführung der Verriegelungsstifte 24, 26 in ihre verriegelte Position axial zusammengedrückt werden; wenn die Rastnasen 52, 54 in die Rastnuten 58, 60 eingreifen, stellen die Elastomerringe 62, 64 die dauerhafte formschlüssige Verriegelung der Bauteilverbindung sicher.The locking pins 24 and 26 each have a detent 52 and 54 at their ends on, as described in more detail below, for locking the attachment serve. So that the locking pins 24, 26 provided with the detent 52, 54 through those in the upper and lower bearing eyes 28a and 30a or 28b and 30b and in the Bearing sleeves 36 provided openings can be inserted, have the mentioned components each have an inner groove 56, with the help of which with the detent 52, 54 provided locking pins 24, 26 are inserted through the openings can. When the two locking pins 24, 26 through the openings have been inserted, the two locking pins 24, 26 by 180 ° rotated, whereby the locking lugs 52, 54 each in one on the lower bearing eyes 30a, 30b provided locking groove 58 and 60 come into engagement. So that the locking lugs 52, 54 held securely in the two locking grooves 58, 60 are between the two Heads 24a and 26a of the locking pins 24, 26 and the upper bearing eyes 28a and 28b, an elastomer ring 62 and 64 is provided. The elastomer ring 62, 64 can the transfer of the locking pins 24, 26 to their locked position axially be squeezed together; when the locking lugs 52, 54 into the locking grooves 58, 60 intervene, the elastomer rings 62, 64 provide the permanent positive locking the component connection safely.
