Description
Die Erfindung betrifft eine Brennkraftmaschine mit einem Saugrohr, insbesondere Schaltsaugrohren, welches mittels einer auf einer Klappenwelle angeordneten Klappe verschließbar ist, wobei die Klappe mittels einer Clipverbindung auf der Klappenwelle fixiert ist.The invention relates to an internal combustion engine with a suction tube, in particular switching suction, which is closable by means of a valve shaft arranged on a flap, wherein the flap is fixed by means of a clip connection on the flap shaft.
Eine solche Brennkraftmaschine ist Gegenstand der
Als nachteilig erweist sich bei dieser Brennkraftmaschine die mit der Durchbrechung der Klappenwelle einhergehende verringerte Belastbarkeit der Klappenwelle. 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.A disadvantage found in this internal combustion engine associated with the breakthrough of the valve shaft reduced load capacity of the valve shaft. To counteract this disadvantage, the flap shaft therefore has a comparatively large diameter. Furthermore, the introduction of the opening in the valve shaft is associated 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.Against this background, the invention has for its object to realize a secure and cost-effective fixation of the flap on the valve shaft with little effort.
Diese Aufgabe wird gelöst mit einer Brennkraftmaschine gemäß den Merkmalen des Patentanspruchs 1. Die Unteransprüche betreffen besonders zweckmäßige Weiterbildungen der Erfindung.This object is achieved with an internal combustion engine according to the features of
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, therefore, an internal combustion engine is provided in which the flap shaft has a receptacle arranged on its circumference for the rotationally fixed fixing of a projection of the flap. The flap shaft is free from perforations, because the flap is fixed only on the circumference of the valve shaft by the clip connection, while the required for transmitting the rotational movement rotationally fixed fixation is achieved by means arranged on the circumference of the valve shaft receptacle. The recording can be realized with little effort during production or subsequently mounted on the valve shaft, so that in addition 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.It is particularly useful if the projection is positively fixed in the receptacle so as to avoid unwanted slippage of the flap relative to the flap shaft and thus a change in the predetermined angular position.
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 receptacle could engage with a cam in a recess of the flap radially or axially. In contrast, a modification of the present invention in which the receptacle has a radial groove in order to ensure a simple and reliable transmission of the rotational movement is particularly advantageous.
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 purpose, a modification is particularly well if the projection has an over the contour of the flap axially projecting tab, because thereby effective as a flow guide surface of the flap is fully available, while the non-rotatable connection of the flap is realized by means of the tab.
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.It is also particularly practical if the flap has a shape which encloses the flap shaft over more than half the circumference. Here, the clip connection is realized by an elastic expansion of the Ω-shaped region until reaching the valve shaft diameter-related restoring forces, which thus requires no additional shaping or locking lugs.
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.Particularly useful is also an embodiment of the invention, when the recording is performed at the same time for the axial fixation of the flap so as to be able to dispense with further components for determining the relative position between 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 receptacle could have an undercut, in which the projection engages with a widening and the flap is thus fixed axially in both directions. However, another particularly practical shape is achieved in that the flap has a second projection opposite the first projection, which is assigned to a second receptacle of the flap shaft and thereby the flap between the two receptacles is reliably fixed in position.
Hierzu eignet sich insbesondere eine Abwandlung, bei der die Klappe zur Klappenwellenachse symmetrisch ausgeführt ist, um so eine fehlerhafte Montage weitgehend auszuschließen.For this purpose, in particular, a modification is suitable, in which the flap is symmetrical to the flap shaft axis, so as largely to preclude a faulty 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.It is particularly advantageous if the flap shaft is free of perforations, thus avoiding an undesirable reduction in the load capacity, such as the bending load.
Die Erfindung lässt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben. Diese zeigt inThe invention allows numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below. This shows in
