Abstract

The induction system (1) is for an internal combustion engine. It has a central air-collecting and inlet channel and a set of spiral-shaped channels (2) conveying air to the cylinders. The spiral channels may be made of inner (4), and outer (3), pieces which may be sealed together (7,10) where their walls (5) come into contact. There are thin partition walls (11) which separate adjacent spiral channels and have sealing lips (8) bearing against the outer piece.

Description

Die Erfindung betrifft ein Luftansaugkanalsystem für Brennkraftmaschinen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an air intake duct system for internal combustion engines according to the Preamble of claim 1.

Derartige Luftansaugkanalsysteme werden mit spiralförmig verlaufenden Einzelansaug­ kanälen ausgestattet, um raumsparend lange Ansaugkanäle zu realisieren, wobei unter Umständen Vorrichtungen zur Umschaltung auf eine Verkürzung der Ansaugkanäle vor­ gesehen sein können (zum Beispiel DE 38 30 286 A1.Air intake duct systems of this type are provided with a spiral-shaped individual intake ducts to realize space-saving long intake ducts, under Under certain circumstances, devices for switching to shortening the intake ducts can be seen (for example DE 38 30 286 A1.

Aus der DE 89 14 049.4 U1 ist bereits bekannt, ein Verteilergehäuse aus mehreren Teil­ stücken zusammenzusetzen, wobei die in bezug auf einen Sammeleinlaßkanal innenlie­ genden Wandungen von Einzelansaugkanälen und die Wandung des Sammeleinlaß­ kanals von Paßstücken gebildet sind, die von den Dichtflächen ausgehend in die Teil­ stücke eingesetzt sind, wodurch die Herstellung einiger Teile im Druckgußverfahren oder Kokillengußverfahren möglich wird. Es hat sich jedoch gezeigt, daß ein erheblicher Aufwand zu betreiben ist, um die Einzelansaugkanäle gegeneinander abzudichten.DE 89 14 049.4 U1 already discloses a distributor housing made up of several parts pieces to be put together, the in relation to a collective inlet channel walls of individual intake ducts and the wall of the collective inlet channel of adapters are formed, starting from the sealing surfaces in the part pieces are used, which allows the production of some parts in the die casting process or mold casting process is possible. However, it has been shown to be a significant one Effort must be made to seal the individual intake ducts against one another.

Aus der DE 43 29 544 ist eine Saugrohranlage einer Brennkraftmaschine bekannt, bei der zwei Kunststoffschalen mit ihren Dichtebenen zusammengehalten werden, wobei in den Dichtebenen Hohlräume angeordnet sind, die mit einem Verbindungselement aus­ gefüllt sind, das mittels eines Spritzgußwerkzeugs in die Hohlräume eingespritzt wird. Hierbei ist eine längere Abkühl- bzw. Aushärtungszeit notwendig, darüber hinaus kann überschüssiges Einspritzmittel die Form bzw. die Luftkanäle verschmutzen.From DE 43 29 544 an intake manifold system of an internal combustion engine is known from of the two plastic shells are held together with their sealing planes, whereby in the sealing planes cavities are arranged with a connecting element are filled, which is injected into the cavities by means of an injection mold. This requires a longer cooling or curing time, and can also Excess injection agent contaminate the mold or the air channels.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein gattungsgemäßes Luftansaugkanalsystem derart zu gestalten, daß insbesondere die Teilstücke aus Kunst­ stoff gefertigt sind und eine Dichtigkeit erzielt wird, ohne daß flüssige Verbindungsele­ mente, die abkühlen bzw. aushärten, verwendet werden.Proceeding from this, the object of the invention is to create a generic one To design air intake duct system in such a way that in particular the sections of art are made of fabric and a tightness is achieved without liquid connecting elements elements that cool or harden are used.

Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs 1 genannten Merkma­ le gelöst worden. Vorteilhafte Weiterbildungen sind mit den Unteransprüchen angege­ ben.This object is by the Merkma mentioned in the characterizing part of claim 1 le has been solved. Advantageous further developments are specified in the subclaims ben.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfol­ gend beschrieben.An embodiment of the invention is shown in the drawing and will follow described below.

Die Zeichnung zeigt einen Schnitt durch ein Luftansaugkanalsystem 1 für Brennkraftma­ schinen, mit einem zentral angeordneten Sammeleinlaßkanal (nicht dargestellt) und von diesem spiralförmig zu den Zylindern führenden Einzelansaugkanälen 2, gebildet aus Teilstücken 3, die mit in Spiralachsrichtung verlaufenden Dichtflächen (nicht dargestellt) aneinandergefügt und verbunden sind, wobei die in bezug auf den Sammeleinlaßkanal innenliegenden Wandungen der Einzelansaugkanäle 2 und die Wandung des Sammel­ kanals von Paßstücken 4 gebildet sind, die von den Dichtflächen ausgehend in die Teil­ stücke 3 eingesetzt sind.The drawing shows a section through an air intake duct system 1 for internal combustion engines, with a centrally arranged collecting inlet duct (not shown) and of this spiral leading to the cylinders individual intake ducts 2 , formed from sections 3 , which are joined together with sealing surfaces running in the spiral axis direction (not shown) and are connected, wherein the inner walls with respect to the collective inlet duct of the individual intake ducts 2 and the wall of the collecting duct are formed by adapters 4, which are inserted from the sealing surfaces into the partial pieces 3 .

Erfindungsgemäß ist bei diesem Luftansaugkanalsystem vorgesehen, daß die mit Wan­ dungen 5 der Teilstücke 3 abdichtend kontaktierenden Paßstückwände 6 als Elastomer­ dichtelemente 7, 8 ausgebildet und direkt an die Paßstücke 4 angespritzt und in Einbau­ lage elastisch verformt sind.According to the invention, in this air intake duct system, that the compounds with Wan 5 of the sections 3 sealingly contacting Paßstückwände sealing elements 6 as the elastomer 7, 8 is formed and molded directly to the adapters 4 and location in the installation are elastically deformed.

Diese Maßnahme bildet eine einfache Kanalabdichtung, die den Montageaufwand re­ duziert, kostengünstig ist und eine Großserienfertigung ermöglicht. Darüber hinaus läßt sie eine vereinfachte Gestaltung des Ansaugkanalsystems zu. This measure forms a simple channel seal, which re the assembly effort is reduced, inexpensive and enables large-scale production. In addition, leaves a simplified design of the intake duct system.  

Es ist vorteilhaft, wenn die in Schächte 9 eingeschobenen Paßstücke 4 bzw. Elastomer­ dichtelemente 7 mehrere Dichtlippen 10 aufweisen (wie dargestellt) und die als Zwi­ schenwände 11 ausgebildeten Paßstückwände 6 im Stirnwandbereich 12 ein V-förmiges Elastomerdichtelement 8 aufweist, das unter Spreizung der Dichtlippen 13 gegen die Teilstückwandung 5 anliegt.It is advantageous if the fitting pieces 4 or elastomer sealing elements 7 inserted into the shafts 9 have a plurality of sealing lips 10 (as shown) and the fitting piece walls 6 designed as intermediate walls 11 in the end wall region 12 have a V-shaped elastomer sealing element 8 which spreads the sealing lips 13 bears against the section wall 5 .

Es ergeben sich Gewichtserleichterungen gegenüber bekannten Systemen, wenn die Teilstücke 3 aus Metall und die Paßstücke 4 aus Kunststoff bestehen.There are weight reductions compared to known systems if the sections 3 consist of metal and the adapters 4 consist of plastic.
