Stand der TechnikState of the art

Die Erfindung betrifft ein Saugmodul, insbesondere für Brennkraftmaschine mit einem Ansaugtrakt mit wenigstens zwei Ansaugkanälen und jeweils einem Schließmittel in einem Ansaugkanal zur Beeinflussung des Durchflussquerschnittes.The invention relates to a suction module, in particular for internal combustion engine with a Intake tract with at least two intake ports and one closing means in one Intake channel for influencing the flow cross-section.

Ein derartiges Saugmodul ist aus der US 4,823,748 bekannt. Dieses Dokument offenbart eine Ansaugvorrichtung für eine Brennkraftmaschine mit wenigstens zwei Ansaugkanälen, wobei jeweils ein Schließmittel in einem der Ansaugkanäle zur Beeinflussung eines Durchflussquerschnittes vorgesehen ist. Diese Schließmittel werden von einem gemeinsamen Betätigungsmittel über Kupplungsmittel angesteuert. Ein Toleranzausgleich zwischen Betätigungsmittel und Schließmittel wird über einen elastischen Bereich erreicht, wobei die Elastizität durch gesonderte elastische Bauteile erzeugt wird.Such a suction module is known from US 4,823,748.

Zur Verbindung der Welle 19 mit der Welle 20 dient eine in Fig. 1b vergrößert gezeigte Kunststoffkupplung 22, die an beiden Stirnseiten mit einer Vierkantöffnung 23, 24 versehen ist. Die linke und die rechte Vierkantöffnung sind um ca. 1° gegeneinander verdreht, um eine Vorspannung zwischen den beiden Klappen 17 und 18 zu realisieren und zu gewährleisten, dass die Klappen nacheinander in geschlossenem Zustand anliegen. Durch konstruktive Ausgestaltungen wird gewährleistet, dass die Klappen in offenem Zustand trotz unterschiedlicher Positionen den optimalen Luftdurchsatz ermöglichen. Die Vorspannkraft kann über Verdrehung der Kunststoffkupplung und dem ausgewählten Material eingestellt werden. Gerade auch bei unterschiedlichen Temperaturen wirkt sich die Vorspannung und der Versatz dahingehend aus, dass unabhängig von der Umgebungstemperatur die miteinander gekoppelten Klappen wirksam schließen.The illustration according to FIG. 1a shows a flap frame 11 and a part shown further flap frame 12. Each flap frame has an inlet 13, 14th and an outlet 15, 16. Within the flap frame 11 is shown in dashed lines Flap 17 is arranged. The two flaps 17 and 18 have a steel square as a core. This steel square is guided to the outside and in the drawing as a shaft 19, 20 shown. The shaft ends are also formed as a square 21. To the connection the shaft 19 with the shaft 20 serves a plastic coupling shown enlarged in Fig. 1b 22, which is provided at both ends with a square opening 23, 24.
