Description

Die Erfindung betrifft ein Saugmodul, insbesondere für Brennkraftmaschinen mit wenigstens einem Ansaugtrakt. Derartige Saugmodule sind bekannt, z. B. aus der deutschen Patentanmeldung DE 40 32 250.The invention relates to a suction module, in particular for Internal combustion engines with at least one intake tract. Such Suction modules are known, e.g. B. from the German patent application DE 40 32 250.

Will man derartige Saugmodule in z. B. PKWs verwenden, so ist daran nachteilig, daß sie während des gesamten Betriebszyklus einen Drehschieber im Strömungsquerschnitt aufweisen, der Strömungsverluste verursacht. Weiter ist daran nachteilig, daß durch die dort notwendige Baulänge des Gesamtdrehschiebers Toleranzprobleme auftreten.If you want such suction modules in z. B. use cars, so disadvantageous in that they operate throughout the operating cycle have a rotary valve in the flow cross section, the Flow losses caused. Another disadvantage is that due to the required overall length of the rotary valve Tolerance problems occur.

Man könnte nun das ganze Bauteil aus Guß herstellen. Dies ist aber einmal kostenaufwendig in der Herstellung, es würde das Saugmodul verteuern. Zum anderen würde es das Gewicht erhöhen.The entire component could now be made from cast iron. This is but once costly to manufacture, it would Make suction module more expensive. Second, it would increase weight.

Es ist somit Aufgabe der Erfindung, ein Saugmodul der eingangs genannten Art dahingehend zu verbessern, daß ein einfach zu erzeugendes, leicht zu montierendes und zuverlässig arbeitendes billiges Saugmodul entsteht.It is therefore an object of the invention to provide a suction module to improve the kind mentioned that an easy to generating, easy to assemble and reliable working cheap suction module is created.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Ansaugtrakt wenigstens zwei Saugrohröffnungen aufweist und wenigstens eine Saugrohröffnung des Ansaugtraktes mit unveränderbarem Querschnitt in die Brennkraftmaschine führt und wenigstens eine andere Saugrohröffnung desselben Ansaugtrakts mittels eines Drehschiebers mit der Brennkraftmaschine verbunden ist.According to the invention this object is achieved in that the Intake tract has at least two intake pipe openings and at least one intake pipe opening of the intake tract unchangeable cross section leads to the internal combustion engine and at least one other intake manifold opening of the same intake tract  connected to the internal combustion engine by means of a rotary valve is.

Im Betriebszuständen, in denen nur ein Teil des Saugrohrquerschnitts benötigt wird, behindert kein zusätzliches Teil den Strömungswiderstand, was einem verminderten Verbrauch entgegenkommt. In Betriebszuständen, in denen ein erweiterter Querschnitt erforderlich ist, wird über den zuschaltbaren Drehschieber die Querschnittsfläche optimal angepaßt.In operating conditions in which only a part of the Intake manifold cross section is required, does not hinder any additional Part of the flow resistance, which reduces consumption accommodates. In operating conditions in which an extended Cross section is required, is on the switchable Rotary valve optimally adapted to the cross-sectional area.

Eine vorteilhafte Weiterbildung sieht vor, daß der Drehschieber im Flansch des Saugmoduls angeordnet ist. Diese Anordnung erleichtert sowohl die Montage als auch die Wartung der Drehschiebereinheiten. Weiter läßt diese Variante unterschiedliche Materialkombinationen zwischen Zylinderkopf, Flansch und Drehschieber zu.An advantageous development provides that the rotary valve is arranged in the flange of the suction module. This arrangement facilitates both assembly and maintenance of the Rotary vane units. This variant leaves further different material combinations between cylinder head, Flange and rotary valve too.

Weiterhin kann man vorteilhafterweise vorsehen, daß der Drehschieber symmetrisch zu seiner Längsachse ist. Durch die symmetrische Ausgestaltung ergeben sich Vorteile sowohl hinsichtlich der Herstellung als auch im Betrieb des Drehschiebers.Furthermore, one can advantageously provide that the Rotary valve is symmetrical to its longitudinal axis. Through the Symmetrical design gives advantages both with regard to the manufacture and operation of the Rotary valve.

Eine weitere vorteilhafte Weiterbildung sieht vor, daß der Drehschieber schwimmend gelagert ist. Hinsichtlich der Frage der Einbautoleranzen sowie der Schallerzeugung bzw. -übertragung ergeben sich in der beschriebenen Variante deutliche Vorteile.Another advantageous further development provides that the Rotary slide valve is floating. With regard to the question of Installation tolerances and sound generation or transmission there are clear advantages in the variant described.

Eine vorteilhafte Weiterbildung ergibt sich, wenn der Drehschieber und/oder das Saugmodul aus Kunststoff besteht. Durch die Ausführung in Kunststoff lassen sich klare Gewichts- und Kostenvorteile erzielen.An advantageous further development results if the Rotary valve and / or the suction module consists of plastic. By the execution in plastic can be clear weight and Achieve cost advantages.

Zusätzliche vorteilhafte Weiterbildungen ergeben sich aus den restlichen Unteransprüchen.Additional advantageous developments result from the remaining subclaims.

Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.These and other features of preferred developments of the In addition to the claims go from the invention  Description and the drawings, the individual Features individually or in groups in the form of Sub-combinations in the embodiment of the invention and on other areas to be realized and beneficial as well as for Protectable versions can present themselves for the here Protection is claimed.

In der Zeichnung zeigen:The drawing shows:

Fig. 1 eine Draufsicht des Saugmoduls, Fig. 1 is a plan view of the intake module,

Fig. 2 ein Schnitt entlang der Linie A-A, Fig. 2 is a section along the line AA,

Fig. 3 ein Schnitt durchs Drehschiebergehäuse, Fig. 3 is a section through the rotary valve housing,

Fig. 4 eine Draufsicht in Pfeilrichtung X, Fig. 4 is a plan view in the arrow direction X,

Fig. 5 Drehschieber, schwimmend gelagert,Stored Fig. 5 rotary valve floating,

Fig. 6 Drehschieber, ballig gelagert. Fig. 6 rotary valve, crowned.

Das Saugmodul besteht, wie in Fig. 1 dargestellt, aus Saugrohr 1, Flansch 2 und Unterdruckdose 3. Die Integration von Drehschieber 4 wird im Schnitt sowohl in Fig. 2 als auch in Fig. 3 in seiner Einbauposition im Flansch 2 dargestellt.As shown in FIG. 1, the suction module consists of suction tube 1 , flange 2 and vacuum socket 3 . The integration of rotary valve 4 is shown on average in both the Fig. 2 and Fig. 3 in its installation position in the flange 2 .

Die Symmetrie bezüglich der Längsachse wird besonders in Fig. 3 deutlich. Der Drehschieber 4 reguliert lediglich den Strömungsquerschnitt einer der beiden Saugrohröffnungen 5, so daß die andere Saugrohröffnung 6 stets ohne strömungswiderstandserhöhende Elemente das Verbrennungsgemisch weiterleiten kann. Die Trennung der zugehörigen Saugrohröffnungen 5 und 6 im Flanschbereich wird in Fig. 3 deutlich. Diese Trennung der Öffnungen sowie das bedarfsweise Öffnen bzw. Schließen durch Drehschieber 4 garantiert eine optimale Verbrennung in jedem Betriebszustand sowie die daraus resultierende Verringerung des Kraftstoffverbrauchs. Der Einsatz magerer Mischungen wird so in allen Betriebszuständen möglich. Die Verwendung von Kunststoff als Werkstoff für Saugrohr 1, Flansch 2 und Drehschieber 4 reduziert das Gewicht sowie die Herstellkosten.The symmetry with respect to the longitudinal axis is particularly evident in FIG. 3. The rotary valve 4 only regulates the flow cross section of one of the two intake pipe openings 5 , so that the other intake pipe opening 6 can always pass on the combustion mixture without elements which increase the flow resistance. The separation of the associated intake manifold openings 5 and 6 in the flange area is clear in FIG. 3. This separation of the openings as well as the opening or closing by means of rotary valve 4 as required guarantees optimal combustion in every operating state and the resulting reduction in fuel consumption. The use of lean mixtures is possible in all operating conditions. The use of plastic as the material for intake manifold 1 , flange 2 and rotary valve 4 reduces the weight and the manufacturing costs.

Die schwimmende Lagerung von Drehschieber 4 erfolgt mittels einer mit Gleitmitteln dotierten Kunststoffbuchse 8 auf der Drehschieberachse 7 sowie des dazugehörigen O-Rings 9, der in einer Gehäusevertiefung Platz findet.The floating mounting of rotary valve 4 takes place by means of a plastic bushing 8 doped with lubricants on the rotary valve axis 7 and the associated O-ring 9 , which is accommodated in a housing recess.

In einem weiteren Ausführungsbeispiel wird, wie in Fig. 6 dargestellt, die Drehschieberachse 7 ballig ausgeführt und die Werkstoffkombination Achse/Lagerbuchse mit gleitmitteldotiertem Kunststoff gewählt.In a further exemplary embodiment, as shown in FIG. 6, the rotary slide axis 7 is made spherical and the material combination axis / bearing bush is selected with plastic doped with lubricant.
