Abstract

The shaft is born in a divided air intake channel housing. One housing half (5) has bearing shell half sections (6) of plastic, bearing metal, etc. Each section has a counter half section formed by a flat spiral spring (7). The bearing shell part (8) of the counter section is loaded by a spring leg (10), which is deformed by the second housing half (9) during assembly. The flat spiral spring has a further spring leg (14), which is inserted into a holder aperture (15) of the bearing shell half section, and aligns the spring relative to the shaft (3).

Hierbei bietet sich eine in Längsrichtung erfolgende Teilung des Gehäuses an, damit die Schaltklappenwelle eingebaut werden kann.Here, a division of the housing in the longitudinal direction is appropriate, so that the Switch valve shaft can be installed.

Es hat sich nun gezeigt, daß die im Luftansaugkanalsystem auftretenden Luftschwingungen die Schaltklappenwelle zum Schwingen bringt, so daß die Welle innerhalb ihrer Gehäusela­ gerung bewegt wird und Geräusche erzeugt, die als störend empfunden werden.It has now been shown that the air vibrations occurring in the air intake duct system causes the switching valve shaft to vibrate, so that the shaft within its housing movement and produces noises that are perceived as disturbing.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, Maßnahmen aufzufinden, mit denen eine Geräuschreduzierung erreicht wird.Proceeding from this, the object of the invention is to find measures with which noise reduction is achieved.

Diese Aufgabe ist bei dem angegebenen Luftansaugkanalsystem durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöst worden. Vorteilhafte Weiterbildungen sind mit den Unteransprüchen angegeben.This task is in the specified air intake duct system by the Characteristic of claim 1 specified features have been solved. Advantageous further developments are specified in the subclaims.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in the drawing and will described below.

Fig. 1 zeigt einen Schnitt eines Luftansaugkanalsystems 1 einer Brennkraftma­ schine mit einer Anordnung zur Lagerung einer mehrere Schaltklappen 2 tra­ genden Schaltklappenwelle 3 in einem in Längsrichtung der Welle 3 geteilten Luftansaugkanalsystem-Gehäuse 4, wobei eine der Gehäusehälften 5 aus Kunst­ stoff, Lagermetall oder einem Mehrstoff bestehende Lagerhalbschalenstücke 6 aufweist, in die die Schaltklappenwelle 3 eingelegt ist. Erfindungsgemäß ist nun vorgesehen, daß jedes Lagerhalbschalenstück 6 ein von einer Bandfeder 7 gebil­ detes Gegenhalblager aufweist, deren Lagerschalenabschnitt 8 unter der Ver­ spannkraft eines von der zweiten Gehäusehälfte 9 beim Zusammenbau verform­ ten Federschenkels 10 steht. Fig. 1 shows a section of an air intake duct system 1 of an internal combustion engine with an arrangement for mounting a plurality of switching flaps 2- carrying switching flap shaft 3 in a longitudinally divided shaft 3 of the air intake duct system housing 4 , one of the housing halves 5 being made of plastic, bearing metal or one Multi-material bearing half-shell pieces 6 , in which the switching valve shaft 3 is inserted. According to the invention it is now provided that each bearing half-shell piece 6 has a gebil det by a band spring 7 counter-half bearing, the bearing shell section 8 under the United tensioning force of one of the second housing half 9 during assembly deform spring legs 10 is.

Dieses Luftkanalsystem 1 ermöglicht das Öffnen und Schließen eines Kurz­ schlußkanals 11 durch die Schaltklappen 2, der zwischen einem Sammeleinlaß 12 und zu den einzelnen Zylindern der Brennkraftmaschine führende Einzelan­ saugkanälen 13 besteht, womit die Leistungsabgabe der Brennkraftmaschine be­ einflußt werden kann. Vorteilhafterweise ist vorgesehen, daß die Bandfeder 7 einen weiteren Federschenkel 14 aufweist, der in eine Aufnahmeöffnung 15 des Lagerhalbschalenstücks 6 eingeschoben ist und die Bandfeder 7 in bezug auf die Welle 3 ausrichtet. Darüber hinaus kann der in die Aufnahmeöffnung 15 einge­ setzte Federschenkel 14 einem Verklippsansatz 16 aufweisen, der in eine Ver­ klippsöffnung der Aufnahmeöffnung 15 einrastet bzw. in die Wandung der Auf­ nahmeöffnung 15 eingedrückt wird. Es kann vorgesehen sein, daß die Lager­ halbschalenstücke 6 direkt an der Gehäusehälfte 5 angespritzt, mit der Gehäuse­ hälfte 5 verspritzt oder in die Gehäusehälfte 5 eingesetzt sind.This air duct system 1 enables the opening and closing of a short-circuit duct 11 through the switching flaps 2 , the suction ducts 13 leading between a collecting inlet 12 and the individual cylinders of the internal combustion engine, so that the power output of the internal combustion engine can be influenced. It is advantageously provided that the band spring 7 has a further spring leg 14 , which is inserted into a receiving opening 15 of the half-shell part 6 and aligns the band spring 7 with respect to the shaft 3 . In addition, the spring leg 14 inserted into the receiving opening 15 may have a clip-on approach 16 which engages in a clip-on opening of the receiving opening 15 or is pressed into the wall of the receiving opening 15 . It can be provided that the bearing half-shell 6 pieces injection-molded directly on the housing half 5, half of the housing 5 splashed or are inserted into the housing half. 5
