Description

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 an intake tract having at least two intake ports and in each case a closing means in an intake passage 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 from the US 4,823,748 known. This document discloses an intake device for an internal combustion engine having at least two intake ports, wherein in each case a closing means is provided in one of the intake ports for influencing a flow cross-section. These closing means are controlled by a common actuating means via coupling means. A tolerance compensation between the actuating means and closing means is achieved via an elastic region, wherein the elasticity is generated by separate elastic components.

Aus der US 4,566,424 ist eine Drosselklappenspeicherung zu entnehmen. Diese arbeitet mit zwei getrennten parallel angeordneten Drosselklappen. Die beiden Drosselklappenwellen sind über ein elastisches Federglied miteinander verbunden. Bei solchen Anordnungen besteht die Gefahr, dass eine exakte Zuordnung der Drosselklappen und damit ein exaktes Fluchten der Drosselklappen nicht möglich ist bzw. über eine aufwendige Justage eingestellt werden muss. Selbst eine einmal eingestellte Zuordnung stellt nicht sicher, dass die Drosselklappen über den gesamten Betriebszeitraum parallel arbeiten.From the US 4,566,424 is to take a throttle valve storage. This works with two separate parallel throttle valves. The two throttle shaft are connected to each other via an elastic spring member. In such arrangements, there is the danger that an exact assignment of the throttle valves and thus an exact alignment of the throttle valves is not possible or must be set via a complex adjustment. Even a once set assignment does not ensure that the throttle valves work in parallel over the entire operating period.

Der Aufbau ist jedoch aufwendig und hat den Nachteil, dass aufgrund von Fertigungstoleranzen der verschiedenen Bauteile auch die elastischen Mittel nicht mehr in der Lage sind, diese Toleranzen auszugleichen.However, the structure is complicated and has the disadvantage that due to manufacturing tolerances of the various components and the elastic means are no longer able to compensate for these tolerances.

Es ist ferner aus der US 6,032,634 eine Klappe zum Verschließen oder Öffnen eines Ansaugkanals bekannt. Es handelt sich hier um eine einzelne Klappe, deren Toleranzen unerheblich sind, da lediglich ein einziger Kanal verschlossen oder geöffnet werden muss.It is also from the US 6,032,634 a flap for closing or opening a suction channel known. This is a single flap, the tolerances are insignificant, since only a single channel must be closed or opened.

Aufgabe der Erfindung ist es, ein Saugmodul mit Schließmitteln in Ansaugkanälen eines Ansaugtraktes zu schaffen, das die Nachteile des Standes der Technik vermeidet, in der Herstellung einen geringen Aufwand erfordert und eine zuverlässige Funktion sicherstellt.The object of the invention is to provide a suction module with closing means in intake ducts of an intake tract which avoids the disadvantages of the prior art, requires little effort in the production and ensures a reliable function.

Diese Aufgabe wird durch die Merkmale des unabhängigen Anspruches 1 gelöst. Der wesentliche Vorteil der Erfindung liegt darin, dass das gemeinsame Betätigungsmittel, welches aus zwei miteinander fluchtend angeordneten Drehwellen besteht, über Kupplungsmittel miteinander verbunden wird, wobei die Kupplungsmittel einen definierten Winkelversatz zwischen den mit dem jeweiligen Kupplungsmittel verbundenen Drehwellen erzeugt. Dies bedeutet, dass aufgrund der Elastizität der gesamten Betätigungsmittel das Schließen aller Ansaugkanäle zuverlässig gewährleistet ist.This object is solved by the features of independent claim 1. The essential advantage of the invention is that the common actuating means, which consists of two aligned with each other arranged rotary shafts, is interconnected via coupling means, wherein the coupling means generates a defined angular offset between the rotational shafts connected to the respective coupling means. This means that due to the elasticity of the entire actuating means closing all intake ports is reliably guaranteed.

Weiterbildungsgemäß ist das Kupplungsmittel eine Kunststoffkupplung, welche über eine jeweilige Vierkantverbindung mit jeweils einer Drehwelle verbunden ist, wobei die Vierkantverbindung den definierten Winkelversatz aufweist. Hierfür kann sowohl der Innenvierkant an der Kunststoffkupplung als auch der Außenvierkant an einer Drehwelle versetzt angeordnet sein.According to the invention, the coupling means is a plastic coupling, which is connected via a respective square connection, each with a rotary shaft, wherein the square connection has the defined angular offset. For this purpose, both the inner square on the plastic coupling and the outer square can be arranged offset on a rotary shaft.

In einer alternativen Ausgestaltung ist wenigstens ein Kupplungsmittel eine Torsionsklammer. Diese Torsionsklammer kann aus einem Federblech bestehen und weist ebenfalls den Winkelversatz auf.In an alternative embodiment, at least one coupling means is a torsion clamp. This torsion clamp can consist of a spring plate and also has the angular offset.

Eine weitere alternative Ausgestaltung sieht vor, die Drehwellen über einen Hebel- bzw. einen Federblechmitnehmer zu koppeln. Durch die Anwendung eines Hebels besteht die Möglichkeit, die Verbindung zwischen Hebel und Drehwelle elastisch zu gestalten.A further alternative embodiment provides to couple the rotary shafts via a lever or a Federblechmitnehmer. By using a lever, it is possible to make the connection between lever and rotary shaft elastic.

In vorteilhafter Weise sind für die Schließmittel zwei Stellungen vorgesehen, die mittels des Toleranzausgleiches exakt erreicht werden können. Es handelt sich dabei um die Offen- und die Geschlossenstellung. Jede dieser Stellungen ist durch Anschläge bestimmt.Advantageously, two positions are provided for the closing means, which can be achieved exactly by means of the tolerance compensation. It is the open and the closed position. Each of these positions is determined by stops.

Beschreibung der AusführungsbeispieleDescription of the embodiments

Die Darstellung gemäß Fig. 1a zeigt einen Klappenrahmen 11 sowie einen zum Teil dargestellten weiteren Klappenrahmen 12. Jeder Klappenrahmen weist einen Einlass 13, 14 und einen Auslass 15, 16 auf. Innerhalb des Klappenrahmens 11 ist die gestrichelt dargestellte Klappe 17 angeordnet. Die beiden Klappen 17 und 18 haben einen Stahlvierkant als Kern. Dieser Stahlvierkant ist nach außen geführt und in der Zeichnung als Welle 19, 20 dargestellt. Die Wellenenden sind ebenfalls als Vierkant 21 ausgebildet. 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 as well as a further flap frame 12 shown in part. Each flap frame has an inlet 13, 14 and an outlet 15, 16. Within the flap frame 11, the flap 17 shown in dashed lines is arranged. The two flaps 17 and 18 have a steel square as the core. This steel square is guided to the outside and shown in the drawing as a shaft 19, 20. The shaft ends are also formed as a square 21. To connect the shaft 19 with the shaft 20 is a in Fig. 1b shown enlarged plastic coupling 22, which is provided at both ends with a square opening 23, 24. The left and right square openings are rotated by about 1 ° from each other to realize a bias between the two flaps 17 and 18 and to ensure that the flaps lie successively in the closed state. By constructive configurations it is ensured that the flaps in the open state allow optimum air flow despite different positions. The preload force can be adjusted by turning the plastic coupling and the selected material. Especially at different temperatures, the bias and the offset effect to the effect that regardless of the ambient temperature, the mutually coupled flaps effectively.

Fig. 2a, b zeigt die Verbindung zweier Klappen mit einer sogenannten Torsionsklammer. Gleiche Teile sind mit denselben Bezugszeichen versehen. In Fig. 2a ist die Torsionsklammer 25 als Verbindungsglied zwischen den beiden Wellen 19 und 20 dargestellt. Diese Torsionsklammer besteht, wie in Fig. 2b ersichtlich, aus einem dünnen Verbindungssteg 26 sowie einem rechtsseitigen Klammerelement 27 und einem linksseitigen Klammerelement 28. Beide Klammerelemente sind offen, d.h. aufgrund der Federwirkung der Klammer ist ein zuverlässiger Halt auf der entsprechenden Welle gewährleistet. Auch hier wird der Versatz um beispielsweise 1° realisiert durch ein leichtes Verdrehen der beiden Klammerelemente, was durch eine geringfügige Torsion des Verbindungssteges bewerkstelligt werden kann.Fig. 2a, b shows the connection of two flaps with a so-called torsion clamp. Identical parts are provided with the same reference numerals. In Fig. 2a, the torsion clamp 25 is shown as a connecting member between the two shafts 19 and 20. As can be seen in FIG. 2b, this torsion clamp consists of a thin connecting web 26 and a right-side clamp member 27 and a left-side clamp element 28. Both clamp elements are open, ie due to the spring action of the clamp a reliable hold on the corresponding shaft is guaranteed. Again, the offset is implemented by, for example, 1 ° by a slight twisting of the two clip elements, which can be accomplished by a slight twist of the connecting web.

Fig. 3a, b zeigt eine Variante, bei welcher die Klappe 17 über einen Hebel 29 mitgenommen wird. Der Hebel 29 ist unmittelbar auf der Welle 19 befestigt und besteht beispielsweise aus Kunststoff. Dieser Hebel ist, wie in Fig. 3b gezeigt, mit einem Federblech 30 verbunden. Dieses Federblech 30 ist auf der Welle 20 befestigt. Die Befestigung erfolgt beispielsweise über eine Nietverbindung. Selbstverständlich besteht auch die Möglichkeit, das Federblech auf einem Vierkantanschluss der Welle 20 zu befestigen, d.h. eine verdrehsichere Steckverbindung zwischen Federblech und Welle 20 zu nutzen. Die Verbindung des Federbleches 30 mit dem Hebel 29 erfolgt beispielsweise dadurch, dass der Hebel in seinem äußeren Bereich lediglich geschlitzt ist und das Federblech 30 in diesen Schlitz eingesteckt werden kann.Fig. 3a, b shows a variant in which the flap 17 is entrained via a lever 29. The lever 29 is mounted directly on the shaft 19 and consists for example of plastic. This lever is, as shown in Fig. 3b, connected to a spring plate 30. This spring plate 30 is mounted on the shaft 20. The attachment takes place for example via a riveted joint. Of course, it is also possible to fix the spring plate on a square connection of the shaft 20, i. to use a twist-proof connector between spring plate and shaft 20. The connection of the spring plate 30 with the lever 29, for example, by the fact that the lever is only slotted in its outer region and the spring plate 30 can be inserted into this slot.
