Description

Die Erfindung betrifft eine Klappenvorrichtung für ein Luftansaugkanalsystem einer Verbrennungskraftmaschine nach dem Oberbegriff des Hauptanspruchs.The The invention relates to a flap device for an air intake duct system an internal combustion engine according to the preamble of the main claim.

Derartige Klappenvorrichtungen werden beispielsweise als Schaltklappen zur Änderung der wirksamen Schwingrohrlänge oder als Tumble- oder Drallklappen zur Erhöhung der Zylinderfüllung und/oder zur besseren Verwirbelung im Brennraum in Luftansaugkanalsystemen in bekannter Weise verwendet.such Flap devices, for example, as switching flaps to change the effective vibration tube length or as tumble or swirl flaps to increase the cylinder filling and / or for better turbulence in the combustion chamber in air intake duct systems used in a known manner.

So wird in der DE 102 36 393 A1 ein Luftansaugkanalsystem beschrieben mit einer Tumbleklappenvorrichtung, welche in einem Unterteil des Luftansaugkanalsystems angeordnet ist, wobei diese auch im Oberteil angeordnet sein könnte. In dem den Luftansaugkanal freigebenden Zustand schwenkt diese Klappe in eine Tasche ein, so daß die Klappe den Kanal im wesentlichen verlängert, so daß keine Strömungshindernisse entstehen. Es handelt sich hierbei um eine im Spritzgußverfahren aus Kunststoff hergestellte Klappe, welche einteilig mit der Klappenwelle hergestellt wird. Im Querschnitt ist die Klappe im wesentlichen u-förmig geformt, wobei die Klappenwelle als Wellenstumpf ausgebildet ist, welcher sich jeweils von den beiden Schenkeln des Klappenkörpers an erstreckt.So will in the DE 102 36 393 A1 an air intake duct system described with a Tumbleklappenvorrichtung, which is arranged in a lower part of the air intake duct system, which could also be arranged in the upper part. In the air intake passage releasing state pivots this flap in a pocket, so that the flap extends the channel substantially, so that no flow obstacles arise. It is a valve made of plastic by injection molding, which is made in one piece with the flap shaft. In cross-section, the flap is substantially U-shaped, wherein the flap shaft is formed as a stub shaft, which extends from the two legs of the flap body on.

Ebenfalls bekannt ist aus der WO 02/088533 A1 ein Klappenverband, der aus unterschiedlichen Materialien hergestellt werden kann und zwei Wellenstümpfe an den beiden Enden aufweist. Bei Herstellung aus Metall muss aufgrund der komplizierten Form ein Gussverfahren mit toleranzgenauer Nachbearbeitung verwendet werden. Die Form und die aufwendige Herstellung führen zu erhöhten Kosten und erhöhtem Gewicht der Vorrichtung.Also is known from WO 02/088533 A1 a flap bandage, the different materials can be made and two stub shafts to the has both ends. When making metal must be due the complicated shape of a casting process with tolerance accurate post-processing be used. The shape and the elaborate production lead to increased Cost and increased Weight of the device.

Derartige Kanal bildende Klappen haben jedoch den Nachteil einer erhöhten Temperaturempfindlichkeit und erfüllen zum Teil nicht die gesetzlichen Anforderungen bezüglich ihrer Festigkeit. Aus diesem Grunde wurden derartige Klappen in den letzten Jahren mit einer Stahl- oder Metallseele ausgeführt, welche anschließend entsprechend umspritzt wird. Dies hat jedoch den Nachteil, daß ein zusätzlicher Fertigungsschritt entsteht, so daß die Herstellkosten steigen und die Temperaturunempfindlichkeit beispielsweise bei einem Einsatz im Abgasstrang weiterhin nicht ausreichend groß ist. Des weiteren ist durch die Schrumpfung im Spritzgußprozeß eine toleranzgenaue Fertigung schwierig.such However, channel-forming flaps have the disadvantage of increased temperature sensitivity and fulfill partly not the legal requirements regarding theirs Strength. For this reason, such flaps were in the last Years executed with a steel or metal core, which then accordingly is overmoulded. However, this has the disadvantage that an additional manufacturing step arises, so that the Production costs increase and the temperature insensitivity, for example is still not sufficiently large when used in the exhaust system. Of Another is the shrinkage in the injection molding process a tolerance-accurate production difficult.

Aufgabe der Erfindung ist es daher eine Klappenvorrichtung zu schaffen, welche eine ausreichende Festigkeit und Temperaturbeständigkeit aufweist und in möglichst wenigen Fertigungsschritten toleranzgenau hergestellt werden kann.task The invention is therefore to provide a flap device, which has sufficient strength and temperature resistance has and in as possible a few manufacturing steps can be produced tolerance tolerances.

Diese Aufgabe wird durch den kennzeichnenden Teil des Hauptanspruchs gelöst.These The object is solved by the characterizing part of the main claim.

Es wird somit kein zusätzlicher Fertigungsschritt für eine Kunststoffumspritzung benötigt, wobei gleichzeitig eine ausreichende Festigkeit und Temperaturbeständigkeit erreicht wird. Zusätzlich ist der Klappenkörper auf einfache Art und Weise in eine Stellung drehbar, in der der Klappenkörper eine Innenwand eines umliegenden Kanals im wesentlichen verlängert also durch seine U-Form Kanal bildend ausgeführt ist. Dies verringert die Strömungswiderstände im korrespondierenden Kanal.It will not be additional Production step for a plastic extrusion needed while maintaining sufficient strength and temperature resistance is reached. additionally is the valve body in a simple manner rotatable in a position in which the door body an inner wall of a surrounding channel thus substantially lengthened executed by its U-shape channel forming. This reduces the Flow resistance in the corresponding Channel.

Vorzugsweise ist die Welle aus einem Rundmaterial hergestellt, welches durch Umformung zumindest im Bereich des Klappenkörpers abgeflacht ist. Derartiges Rundmaterial ist kostengünstig und einfach zu bearbeiten, so daß am Rundmaterial nach der Umformung eine glatte Auflagefläche für den Klappenkörper besteht, der dann durch Schweißen, Schrauben oder ähnliches befestigt werden kann.Preferably the shaft is made of a round material, which by Forming is flattened at least in the region of the valve body. such a Round material is inexpensive and easy to work, so that the round material after the Forming a smooth bearing surface for the valve body, then by welding, screws or similar can be attached.

In einer alternativen Ausführungsform ist die Welle aus einem Mehrkantprofil hergestellt, welches im Bereich von Lagerstellen mit Kunststoff umspritzt ist. Hier können beispielsweise Vierkantprofile verwendet werden, so daß ohne eine Umformung des Metallprofils die Klappe befestigt werden kann. Allerdings ist es dann notwendig im Bereich der Lagerstellen eine im Querschnitt runde Fläche herzustellen. Dies erfolgt auf einfache Art und Weise durch Kunststoffumspritzung.In an alternative embodiment the shaft is made of a polygonal profile, which is in the range is encapsulated by bearings with plastic. Here, for example Square profiles are used, so that without a deformation of the metal profile the flap can be attached. However, it is necessary produce a cross-sectionally round surface in the area of the bearing points. This takes place in a simple manner by plastic extrusion.

In einer weiterführenden Ausführung ist die Welle durch Umformung in eine zum Klappenkörper korrespondierende U-Form gebogen. Hierdurch erhält der Klappenkörper eine zusätzliche Stabilität, so dass eine dünne Blechausführung für den Klappenkörper gewählt werden kann. Es handelt sich des weiteren um ein kostengünstiges Umformverfahren zur Herstellung des Klappenverbandes.In a continuing execution is the shaft by forming in a flap body corresponding Bent U-shape. This preserves the valve body an additional Stability, so a thin one sheet design for the door body chosen can be. It is also a cost-effective Forming process for the production of the flap bandage.

In einer alternativen Ausführung ist an Schenkelenden des u-förmigen Klappenkörpers je ein rund ausgebildeter Wellenstumpf geschweißt, wodurch der Materialaufwand verringert wird und eine hohe Festigkeit erhalten bleibt. Die Welle kann dabei entweder als Vollwelle oder als Hohlwelle ausgeführt werden.In an alternative embodiment is at leg ends of the U-shaped door body each welded a round trained stub shaft, reducing the cost of materials is reduced and a high strength is maintained. The wave can be performed either as a solid shaft or as a hollow shaft.

Es wird somit eine Klappenvorrichtung geschaffen, welche eine hohe Lebensdauer und Dauerfestigkeit aufweist. Des weiteren ist auf kostengünstige Art und Weise eine sehr toleranzgenaue Fertigung möglich. Vorteile bezüglich des Einbaus in einen Luftansaugkanalsystem sowie die Verhinderung von Strömungswiderständen im offenen Zustand der Klappe bleiben im Vergleich zu bekannten Ausführungen mit Kunststoffklappen erhalten.It Thus, a flap device is created, which has a high Lifespan and fatigue strength has. Furthermore, is in a cost effective manner and way a very accurate tolerance manufacturing possible. Advantages regarding the Installation in an air intake duct system and the prevention of flow resistance in the open state of the flap remain compared to known designs obtained with plastic flaps.

Ein Ausführungsbeispiel ist in den Zeichnungen dargestellt und wird nachfolgend beschrieben.One embodiment is shown in the drawings and will be described below.

1 zeigt eine perspektivische Ansicht einer erfindungsgemäßen Klappenvorrichtung. 1 shows a perspective view of a flap device according to the invention.

2 zeigt eine alternative Ausführung einer erfindungsgemäßen Klappenvorrichtung in perspektivischer Ansicht. 2 shows an alternative embodiment of a flap device according to the invention in a perspective view.

3 zeigt eine weitere alternative Ausführung einer erfindungsgemäßen Klappenvorrichtung in perspektivischer Ansicht. 3 shows a further alternative embodiment of a flap device according to the invention in a perspective view.

Die in 1 dargestellte Klappenvorrichtung 1 besteht aus einer Metallwelle 2, auf der ein Klappenkörper 3 angeordnet ist.In the 1 illustrated flap device 1 consists of a metal shaft 2 on which a valve body 3 is arranged.

Die Metallwelle 2 besteht dabei aus einem Rundmaterial, welches im Bereich 4 des Klappenkörpers derart verformt ist, daß ein rechteckiges flaches Vierkantprofil entsteht. Diese Umformung kann durch Stauchen oder Plätten erreicht werden.The metal shaft 2 consists of a round material, which is in the range 4 the flap body is deformed such that a rectangular flat square profile is formed. This deformation can be achieved by upsetting or flattening.

Des weiteren ist zu erkennen, daß die Metallwelle 2 in einem Biegeformprozess im Bereich 4 des Klappenkörpers 3 etwa u-förmig gebogen ist, wobei die jeweiligen nicht umgeformten Wellenenden 5, 6 wiederum um etwa 90° zu den Schenkeln des u-förmigen Bereiches in Achsrichtung gebogen sind. Auf dieser Metallwelle 2 ist der Klappenkörper 3 im vorliegenden Beispiel über zwei Schrauben 7 angebracht, wobei auch Schweiß- oder Lötverfahren denkbar sind. Der Klappenkörper 3 ist ebenfalls im wesentlichen u-förmig geformt und korrespondiert zu dem Bereich 4 der Metallwelle 2. Auch der Klappenkörper 3 kann durch Umformen in diese U-Form gebogen werden. Er kann aus Blech oder einem sonstigen Metall hergestellt werden.Furthermore, it can be seen that the metal shaft 2 in a bending process in the area 4 of the valve body 3 bent approximately U-shaped, with the respective non-deformed shaft ends 5 . 6 in turn bent by about 90 ° to the legs of the U-shaped area in the axial direction. On this metal shaft 2 is the valve body 3 in the present example two screws 7 attached, with welding or soldering are conceivable. The valve body 3 is also substantially U-shaped and corresponds to the area 4 the metal shaft 2 , Also the valve body 3 Can be bent by forming in this U-shape. It can be made of sheet metal or other metal.

Die sich axial erstreckenden runden Wellenenden 5, 6 dienen jeweils als Lagerstelle in einem Gehäuse eines Luftansaugkanalsystems.The axially extending round shaft ends 5 . 6 each serve as a bearing in a housing of an air intake duct system.

In der 2 ist eine alternative Ausführungsform dargestellt, wobei gleiche Teile, gleiche Bezugszeichen erhalten.In the 2 an alternative embodiment is shown, wherein like parts, like reference numerals.

Im Vergleich zu der Ausführung aus 1 ist die Metallwelle 2, hier nicht aus einem Rundmaterial sondern aus einem Vierkantmaterial hergestellt, welches lediglich im Querschnitt in U-Form gebogen wird mit den sich axial erstreckenden Wellenenden 5,6. Eine sonstige Bearbeitung ist lediglich im Bereich dieser Wellenenden 5, 6 erforderlich, um eine runde Lagerstelle herzustellen. So ist in 2 das Wellenende 5 mit einer entsprechenden Lagerstelle dargestellt, welche durch einen Umspritzvorgang mit einem Kunststoff hergestellt ist. Auf dem gegenüberliegenden Wellenende 6 ist diese Lagerstelle nicht ausgeführt. Im übrigen entsprechen sich die Darstellungen gemäß 1 und 2.Compared to the execution 1 is the metal shaft 2 , here not made of a round material but of a square material, which is bent only in cross-section in a U-shape with the axially extending shaft ends 5 . 6 , Other processing is only in the area of these shaft ends 5 . 6 required to make a round bearing. So is in 2 the shaft end 5 represented with a corresponding bearing point, which is produced by a extrusion coating with a plastic. On the opposite shaft end 6 this storage location is not executed. For the rest, the illustrations correspond to 1 and 2 ,

Während die Alternative gemäß 1 den Vorteil aufweist, daß keine zusätzliche Umspritzung der Metallwelle mit Kunststoff erforderlich ist, entfällt bei der Ausführung mit dem Vierkantprofil ein Umformen der Metallwelle im Bereich der Klappe. Beide Alternativen sind geeignet, auch bei hohen Temperaturschwankungen eingesetzt zu werden und verfügen des weiteren über eine hohe Festigkeit bei einfacher und kostengünstiger Herstellung und hoher Fertigungsgenauigkeit.While the alternative according to 1 has the advantage that no additional encapsulation of the metal shaft with plastic is required, eliminates in the version with the square profile forming the metal shaft in the flap. Both alternatives are suitable to be used even at high temperature fluctuations and also have a high strength with simple and cost-effective production and high manufacturing accuracy.

Die in 3 dargestellte alternative Klappenvorrichtung 1 ist als vollständiger Klappenverband dargestellt. Die u-förmig gebogenen vier Klappenkörper 3 aus Stahlblech sind an ihren beiden Schenkelenden 8 mit je einem Wellenstumpf 10 verschweißt und somit stoffschlüssig verbunden. Dabei kann der Wellenstumpf 10 entweder außen an den Klappenkörper 3 geschweißt werden oder über ein Loch 9 durch das jeweilige Schenkelende 8 gesteckt werden und von der Klappeninnenseite verschweißt werden. Vorzugsweise wird ein Laserschweißverfahren verwendet.In the 3 illustrated alternative flap device 1 is shown as a complete flap bandage. The U-shaped four flap body 3 made of sheet steel are at their two leg ends 8th each with a stub shaft 10 welded and thus materially connected. In this case, the stub shaft 10 either on the outside of the valve body 3 be welded or over a hole 9 through the respective leg end 8th be plugged and welded from the inside of the flap. Preferably, a laser welding process is used.

Durch eine derartige Ausführung wird das Gewicht weiter reduziert und es entfallen zusätzliche Umformprozesse. Dennoch wird eine deutlich erhöhte Festigkeit im Vergleich zu Kunststoffklappen erzielt.By Such an embodiment the weight is further reduced and it eliminates additional forming processes. Nevertheless, a significantly increased Strength compared to plastic flaps achieved.

Selbstverständlich ist es denkbar, eine andere Form der Klappe beziehungsweise der Metallwelle zu wählen, wobei der besondere Vorteil dieser U-Form darin liegt, daß die Klappe auf diese Art und Weise Kanal bildend genutzt werden kann. Insbesondere bei einer Ausführung gemäß 3 ist dies einfach realisierbar.Of course, it is conceivable to choose a different shape of the flap or the metal shaft, with the particular advantage of this U-shape is that the flap can be used in this way channel forming. In particular, in an embodiment according to 3 this is easily realizable.

Eine Ausführung als Klappenverband ist selbstverständlich auch für eine der Ausführungen gemäß 1 oder 2 möglich. Ein so entstehender Klappenverband erleichtert die Montage.A version as a flap Association is of course also for one of the versions according to 1 or 2 possible. Such a resulting flap bandage facilitates assembly.
