Description
Die Erfindung betrifft eine Klappeneinrichtung für Ansaugrohre, insbesondere von Brennkraftmaschinen, gemäß dem Oberbegriff des Anspruchs 1. Des Weiteren betrifft die Erfindung die Herstellung einer solchen Klappeneinrichtung gemäß Anspruch 7.The The invention relates to a flap device for intake pipes, in particular of internal combustion engines, according to the preamble of claim 1. Furthermore, the invention relates to the production Such a flap device according to claim 7.
Für Klappen- bzw. Abschaltmechanismen in Luftverteilen von Verbrennungsmaschinen werden in Zukunft durch schärfere Abgasgesetzgebungen immer kleinere Spaltmaße bzw. immer größere Dichtheit zwischen Klappen und Rohrkanälen gefordert. Daraus ergeben sich immer größere Probleme bei der Toleranzauslegung der Bauteile, insbesondere hinsichtlich der Wärmeausdehnung der Bauteile. Die Luftverteiler bestehen größtenteils aus thermoplastischem Kunststoff, wogegen die Klappen auf Metallwellen angebracht sind. Die Klappen selber bestehen ebenfalls selbst aus thermoplastischem Kunststoff.For flaps or shutdown mechanisms in air distributors of internal combustion engines will be through sharper in the future Emissions legislation ever smaller gaps or ever greater tightness between flaps and pipe channels required. This results in ever greater problems with the tolerance design the components, in particular with regard to the thermal expansion of the components. The air distributors exist largely made of thermoplastic material, whereas the flaps on metal shafts are attached. The flaps themselves also consist of themselves thermoplastic.
Zur Lösung des Problems werden bislang Kunststoffklappen auf eine Metallwelle aufgeschoben und sind auf dieser Welle axial verschiebbar, um ein Verklemmen der Klappen in den Rohrkanälen durch Wärmeausdehnungen zu verhindern. Bei dieser Konstruktion ist jedoch nachteilig, dass lediglich Wärmeausdehnungen ausgeglichen werden können. Des Weiteren müssen fertigungsbedingte Spaltmaße unbedingt eingehalten werden. Da die Klappe axial auf der Metallwelle verschiebbar ist – auch schwimmend gelagert –, können Relativbewegungen zwischen Klappe und Metallwelle auftreten, die zu einem erhöhten Verschleiß an den Klappen führen können.to solution So far plastic flaps on a metal shaft have become problematic deferred and are axially displaceable on this shaft to a Jamming the flaps in the pipe channels to prevent thermal expansion. In this construction, however, is disadvantageous that only thermal expansions can be compensated. Of Further need production-related gap dimensions necessarily be respected. Since the flap axially displaceable on the metal shaft is - too floating - can Relative movements between flap and metal shaft occur, the to an increased Wear on lead the flaps can.

Der Erfindung liegt die Aufgabe zugrunde, eine Klappeneinrichtung und dessen Herstellung vorzustellen, wobei diese Klappeneinrichtung ein minimales Spaltmaß zwischen Klappe und Rohrkanal realisiert.Of the Invention is based on the object, a flap device and to present its production, this flap device a minimal gap between Realized flap and pipe channel.
Die Erfindung wird durch die Merkmale des unabhängigen Anspruchs 1 und durch die Merkmale des unabhängigen Anspruchs 7 gelöst.The Invention is characterized by the features of independent claim 1 and by the characteristics of the independent Claim 7 solved.
Die Klappeneinrichtung für Ansaugrohre umfasst eine Welle und mindestens eine Klappe, die mit dieser Welle drehfest verbunden ist. Dabei ist um die Klappe ein Ausgleichselement angeordnet, das relativ zur Klappe verschiebbar ist. Zwischen dem Ausgleichselement und der Klappe ist ein Federelement angeordnet. Das Ausgleichselement wird von dem Federelement gegen die Rohrwandung gedrückt, so dass bei geschlossener Stellung der Klappe praktisch kaum ein Spaltmaß zwischen Ausgleichselement und Rohrwandung vorhanden ist. Da das Ausgleichselement federnd gelagert ist, kann es ohne weiteres thermische Ausdehnungen aufnehmen, ohne dass die Klappe sich im Rohr verkeilt.The Flap device for Intake manifold includes a shaft and at least one flap with this Shaft is rotatably connected. It is a compensation element to the flap arranged, which is displaceable relative to the flap. Between the Compensation element and the flap is arranged a spring element. The compensation element is by the spring element against the pipe wall pressed so that in the closed position of the flap virtually no Gap between Compensation element and pipe wall is present. Because the compensation element is resiliently mounted, it can easily thermal expansions record without the flap wedged in the tube.
Erfindungsgemäß ist das Ausgleichselement an der Klappe und/oder Welle verliersicher befestigt. Dies hat den Vorteil, dass das Ausgleichselement einerseits bei der Montage andererseits beim Aufdrehen der Klappe das Ausgleichselement von der Klappe abfällt. Ferner weist das Ausgleichselement mindestens ein Verrastelement auf, das mit einem komplementärgeformten Verrastelement greift, wobei diese beiden Verrastelemente im montierten Zustand zueinander ein Spiel aufweisen. Dabei ist das komplementärgeformte Verrastelement an der Welle geformt. Diese Konstruktion bietet die Möglichkeit einer einfachen Montage des Ausgleichselements an die Klappe. Die Verrastelemente des Ausgleichselementes sind an den freien Enden angeordnet. Damit ist das Ausgleichselement am flexibelsten und bietet das größtmögliche Spiel an, so dass größere Toleranzen und Temperaturschwankungen ausgeglichen werden können.This is according to the invention Compensation element attached to the flap and / or shaft captive. This has the advantage that the compensation element on the one hand during assembly on the other hand, when turning the flap, the compensation element of the flap drops. Furthermore, the compensation element has at least one latching element on that with a complementarily shaped one Latching element engages, with these two latching elements mounted in the Condition to each other have a game. This is the complementarily formed Latching element formed on the shaft. This construction offers the possibility a simple installation of the compensation element to the flap. The Locking elements of the compensation element are at the free ends arranged. Thus, the compensation element is the most flexible and offers the greatest possible game so that larger tolerances and temperature fluctuations can be compensated.
Vorzugsweise ist das Ausgleichselement U-förmig und umklammert im eingebauten Zustand die Kanten der Klappe. Darunter ist zu verstehen, dass das Ausgleichselement entlang des gesamten Umfangs der Klappe angeordnet ist. Vorzugsweise umfasst der Umfang der Klappe eine Führung für das Ausgleichselement auf. Diese Führung verhindert, dass das Ausgleichselement senkrecht zur Klappenfläche verrutschen kann.Preferably the compensation element is U-shaped and clasps the edges of the flap when installed. among them is to be understood that the compensation element along the entire circumference the flap is arranged. Preferably, the circumference of the flap comprises a guide for the compensation element on. This guide prevents the compensation element from slipping perpendicular to the flap surface can.
Vorzugsweise ist das Federelement an der Führung der Klappe und/oder an der Innenkante des Ausgleichselementes angeformt. Mit dieser Ausgestaltung kann ein zusätzliches Bauteil eingespart werden, da die Federwirkung entweder durch die Klappe oder aber durch das Ausgleichselement übernommen wird.Preferably is the spring element on the guide the flap and / or formed on the inner edge of the compensating element. With this embodiment, an additional component can be saved, because the spring action either through the flap or through the Compensation element adopted becomes.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den übrigen abhängigen Ansprüchen angegeben.Further advantageous embodiments of the invention are specified in the remaining dependent claims.
