Um diesem Nachteil entgegenzuwirken weist die Klappenwelle daher einen vergleichsweise großen Durchmesser auf. Weiterhin ist das Einbringen der Durchbrechung in die Klappenwelle mit einem hohen Herstellungsaufwand verbunden.When disadvantageous proves in this internal combustion engine with the Opening of the valve shaft associated reduced load capacity of the Valve shaft. To counteract this disadvantage, the flap shaft therefore a comparatively large one Diameter up. Furthermore, the introduction of the opening connected in the valve shaft with a high production cost.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine sichere und kostengünstige Fixierung der Klappe auf der Klappenwelle mit geringem Aufwand zu realisieren.In front In this background, the invention is based on the object safe and cost effective Fixation of the flap on the valve shaft with little effort too realize.
Diese Aufgabe wird gelöst mit einer Brennkraftmaschine gemäß den Merkmalen des Patentanspruchs 1. Die Unteransprüche betreffen besonders zweckmäßige Weiterbildungen der Erfindung.These Task is solved with an internal combustion engine according to the features of the claim 1. The dependent claims relate to particularly expedient developments the invention.
Erfindungsgemäß ist also eine Brennkraftmaschine vorgesehen, bei der die Klappenwelle eine an ihrem Umfang angeordnete Aufnahme zur drehfesten Fixierung eines Vorsprunges der Klappe aufweist. Die Klappenwelle ist dabei frei von Durchbrechungen, weil die Klappe lediglich am Umfang der Klappenwelle durch die Clipverbindung fixiert wird, während die zur Übertragung der Drehbewegung erforderliche drehfeste Fixierung mittels der am Umfang der Klappenwelle angeordneten Aufnahme erreicht wird. Die Aufnahme kann dabei mit geringem Aufwand bereits bei der Herstellung realisiert oder nachträglich auf der Klappenwelle angebracht werden, so dass zudem eine einfache Einstellbarkeit der Winkelstellung der Klappe möglich ist.According to the invention is thus provided an internal combustion engine, wherein the flap shaft to an arranged circumferentially receptacle for rotationally fixed fixing a Projection of the flap has. The flap shaft is free of breakthroughs, because the flap only at the periphery of the valve shaft is fixed by the clip connection while being transferred the rotational movement required rotationally fixed fixation by means of the Scope of the flap shaft arranged receiving is achieved. The Recording can with little effort already in the production realized or subsequently be mounted on the valve shaft, so that also a simple Adjustability of the angular position of the flap is possible.
Dabei ist es besonders zweckmäßig, wenn der Vorsprung in der Aufnahme formschlüssig fixiert ist, um so einen unerwünschten Schlupf der Klappe gegenüber der Klappenwelle und damit eine Veränderung der vorbestimmten Winkelstellung zu vermeiden.there it is particularly useful if the Projection is positively fixed in the receptacle, so as a undesirable Slip the flap opposite the flapper shaft and thus a change in the predetermined angular position to avoid.
Die Aufnahme könnte mit einer Nocke in eine Aussparung der Klappe radial oder axial eingreifen. Besonders vorteilhaft ist hingegen eine Abwandlung der vorliegenden Erfindung, bei der die Aufnahme eine radiale Nut aufweist, um so eine einfache und zuverlässige Übertragung der Drehbewegung sicherzustellen.The Could be recording with a cam in a recess of the flap radially or axially intervention. In contrast, a modification of the present invention, wherein the receptacle has a radial groove, so a simple and reliable transmission to ensure the rotational movement.
Hierzu eignet sich eine Abwandlung besonders gut, wenn der Vorsprung eine über die Kontur der Klappe axial vorspringende Lasche hat, weil dadurch die als Strömungsleitelement wirksame Fläche der Klappe uneingeschränkt zu Verfügung steht, während die drehfeste Verbindung der Klappe mittels der Lasche realisiert ist.For this a modification is particularly well if the projection on the one Contour of the flap has axially projecting tab, because thereby the as a flow guide effective area of Flap unrestricted available stands while realized the non-rotatable connection of the flap by means of the tab is.
Besonders praxisnah ist es auch, wenn die Klappe eine Ausformung aufweist, welche die Klappenwelle über mehr als den halben Umfang einschließt. Hierbei wird die Clipverbindung durch eine elastische Aufweitung des Ω-förmigen Bereichs bis zum Erreichen des Klappenwellendurchmessers bedingten Rückstellkräfte realisiert, die somit keine zusätzlichen Formgebung oder Rastnasen erfordert.Especially it is also practical if the flap has a shape, which the flap shaft over more than half the circumference. This is the clip connection by an elastic widening of the Ω-shaped area until reaching realized the valve shaft diameter conditional restoring forces, which thus no additional Shaping or locking lugs required.
Besonders zweckmäßig ist dabei auch eine Ausführungsform der Erfindung, wenn die Aufnahme zugleich zur axialen Fixierung der Klappe ausgeführt ist, um so auf weiteren Bauelemente zur Festlegung der relativen Position zwischen der Klappe und der Klappenwelle verzichten zu können.Especially is appropriate while also an embodiment the invention, when the recording at the same time for axial fixation the flap is executed, so on on other components to determine the relative position to be able to do without the flap and the flap shaft.
Die Aufnahme könnte eine Hinterschneidung aufweisen, in welcher der Vorsprung mit einer Aufweitung eingreift und die Klappe somit axial in beiden Richtungen festgelegt ist. Eine andere besonders praxisgerechte Formgebung wird jedoch dadurch erreicht, dass die Klappe einen dem ersten Vorsprung gegenüberliegend angeordneten zweiten Vorsprung aufweist, welche einer zweiten Aufnahme der Klappenwelle zugeordnet ist und dadurch die Klappe zwischen den beiden Aufnahmen in ihrer Position zuverlässig festgelegt ist.The Could be recording have an undercut, in which the projection with a Expansion engages and the flap thus axially in both directions is fixed. Another particularly practical shape However, this is achieved by the flap being opposite the first projection arranged second projection having a second receptacle the flapper shaft is assigned and thereby the flap between the two recordings in their position is reliably fixed.
Hierzu eignet sich insbesondere eine Abwandlung, bei der die Klappe zur Klappenwellenachse symmetrisch ausgeführt ist, um so eine fehlerhafte Montage weitgehend auszuschließen.In particular, an Ab is suitable for this purpose conversion, in which the flap to the valve shaft axis is symmetrical, so as to largely rule out incorrect assembly.
Dabei ist es besonders günstig, wenn die Klappenwelle frei von Durchbrechungen ist, um somit eine unerwünschte Reduzierung der Belastbarkeit, beispielsweise der Biegelast, zu vermeiden.there is it particularly favorable when the flap shaft is free of openings, thus a undesirable Reduction of load capacity, such as the bending load, too avoid.
