Description

Die Erfindung bezieht sich auf eine Kunststoffsauganlage der im Oberbegriff des ersten Anspruchs genannten Art sowie auf ein Verfahren zu ihrer Herstellung nach dem Ober­ begriff des Anspruchs 8.The invention relates to a plastic suction system the type mentioned in the preamble of the first claim and on a process for their manufacture according to the Ober Concept of claim 8.

Aus der automobiltechnischen Zeitschrift 86 (1984) Heft 3 Seite 92, 93 ist es bekannt, Sauganlagen mit integriertem Luftsammler aus zwei Halbschalen herzustellen. Diese Halbschalen werden in Spritzgußtechnik hergestellt und dann anschließend in einem separaten Arbeitsgang ver­ schweißt. Derartig hergestellte Sauganlagen eignen sich zum Einsatz in Dieselmotoren.From the automotive magazine 86 (1984), issue 3 Pages 92, 93 it is known suction systems with integrated To produce air collectors from two half shells. These Half shells are manufactured using injection molding technology and then ver in a separate step welds. Suction systems manufactured in this way are suitable for use in diesel engines.

Beabsichtigt man derartig hergestellte Sauganlagen in Ot­ tomotoren zu verwenden, so muß sichergestellt werden, daß die dort möglicherweise auftretenden Druckstöße durch Flammrückschlag vom Verbrennungsraum nicht zu einem Auf­ platzen der Schweißnähte führen. Deshalb ist bereits in DE-A-34 05 456 vorgeschlagen worden, bei Kunststoffhalb­ schalen diese zu verkleben und darüber hinaus noch durch Verbindungselemente zu umklammern. Die dort beschriebene Anordnung hat sich zwar bewährt, ist jedoch aufwendig in der Fertigung.Are intended such suction systems in Ot to use tomotors, it must be ensured that the pressure surges that may occur there Flashback from the combustion chamber does not open up burst the weld seams. Therefore is already in DE-A-34 05 456 has been proposed for plastic half form these to glue and also through Clasp fasteners. The one described there Arrangement has proven itself, but is expensive in manufacturing.

Aufgabe der vorliegenden Erfindung ist es, eine Kunst­ stoffsauganlage der Eingangs genannten Art so weiterzu­ bilden, daß sie preiswert herzustellen ist und den Be­ lastungen im Betrieb bei einem Ottomotor standhält.The object of the present invention is an art Substance suction system of the type mentioned so on form that it is inexpensive to manufacture and the Be withstands loads during operation with a gasoline engine.

Diese Aufgabe wird erfindungsgemäß durch die kennzeich­ nenden Merkmale des ersten Anspruchs gelöst. Dadurch, daß die Verbindungselemente nur um den Luftsammler angeordnet werden, vereinfacht sich die Herstellung. Eine weitere Vereinfachung wird dadurch erzielt, daß das Drosselklap­ penstutzengehäuse direkt mit den Verbindungselement ein­ stückig hergestellt ist. Durch die Integration der Verbindungselemente mit dem Drosselklappenstutzengehäuse wird eine wesentliche Vereinfachung und Erhöhung der Si­ cherheit der Kunststoffsauganlage erzielt. Es ist nun nicht mehr notwendig, ein separat hergestelltes Drossel­ klappenstutzengehäuse in einem separaten Arbeitsgang am Luftsammler zu befestigen. Dadurch konnte die Berstdruck­ festigkeit bei Raumtemperatur auf 5 bar gesteigert wer­ den, so daß derartige Kunststoffsauganlagen problemlos bei Ottomotoren verwendet werden können.This object is inventively characterized by nenden features of the first claim solved. As a result of that the connecting elements are only arranged around the air collector production is simplified. Another Simplification is achieved in that the throttle valve pen socket housing directly with the connecting element is made in pieces. By integrating the Fasteners with the throttle body becomes a significant simplification and increase in Si achieved safety of the plastic suction system. It is now no longer necessary, a separately manufactured choke flap socket housing in a separate operation on Attach air collector. This allowed the burst pressure strength at room temperature increased to 5 bar the, so that such plastic suction systems easily can be used with petrol engines.

Die Weiterbildung nach Anspruch 2 beschreibt bevorzugte Bereiche für den Einsatz des Verbindungselementes. Diese Anordnung ist besonders vorteilhaft bei Kunststoffluft­ sammlern für Reihenmotore.The development according to claim 2 describes preferred Areas for the use of the connecting element. These Arrangement is particularly advantageous with plastic air collectors for in-line engines.

Durch die Ausbildung nach Anspruch 3 wird der gesamte Verbindungsflansch des Luftsammlers mit Verbindungsele­ menten geklammert, wodurch die Berstdruckfestigkeit wei­ ter erhöht wird. Through the training according to claim 3, the entire Connection flange of the air collector with connection element elements bracketed, whereby the burst pressure resistance white ter is increased.  

Eine weitere Steigerung der Wirkung der Verbindungsele­ mente wird durch die Ausbildung nach Anspruch 4 erreicht.A further increase in the effect of the connecting elements Mente is achieved by the training according to claim 4.

Das Verbinden der klammerartigen Enden der Verbindungs­ elemente in Abständen über Stege erhöht deren Wirkung ge­ gen Aufbiegen.Joining the clip-like ends of the connector Elements spaced apart by bars increase their effectiveness towards the bend.

Anspruch 6 beschreibt eine bevorzugte Materialauswahl. Da der Materialanteil der Verbindungselemente und des Dros­ selklappenstutzengehäuses zum Material des Luftsammlers und der Saugrohre sowie deren Verbindungsflansche zum Zylinderkopf etwa 20 zu 80 ist, kann eine derart herge­ stellte Kunststoffsauganlage problemlos recycelt werden, da bei diesem Materialverhältnis problemlos ein Blend hergestellt werden kann.Claim 6 describes a preferred choice of material. There the material content of the connecting elements and the Dros Selflap socket housing for the material of the air collector and the suction pipes and their connecting flanges to Cylinder head is about 20 to 80, such a herge provided plastic suction system can be easily recycled, because with this material ratio a blend is no problem can be manufactured.

Vorteilhaft ist es, alle Verbindungselemente sowie das Drosselklappenstutzengehäuse in einem einzigen Arbeits­ gang herzustellen.It is advantageous to all connecting elements and that Throttle body in a single operation gear manufacture.

Ein geeignetes Herstellungsverfahren beschreiben die An­ sprüche 8 und 9.A suitable production process describes the An sayings 8 and 9.

Im folgenden wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Es stellen dar:In the following, the invention is based on a preferred Embodiment explained in more detail. They represent:

Fig. 1 Eine schematisierte Draufsicht auf eine erfin­ dungsgemäß aufgebaute Kunststoffsauganlage; Fig. 1 is a schematic plan view of an inventively constructed plastic suction system;

Fig. 2 einen Querschnitt durch den Luftsammler und das Drosselklappenstutzengehäuse der Kunst­ stoffsauganlage nach Fig. 1; Figure 2 shows a cross section through the air collector and the throttle body of the plastic suction system according to Fig. 1.

Fig. 3 Einen Querschnitt durch zwei benachbarte Saug­ rohre der Kunststoffsauganlage nach Fig. 1. Fig. 3 shows a cross section through two adjacent suction tubes of the Kunststoffsauganlage of FIG. 1.

Die in Fig. 1 dargestellte Kunststoffsauganlage ist für einen Reihen-6-Zylinder-Motor konzipiert. Hierauf ist je­ doch die Erfindung prinzipiell nicht beschränkt.The plastic suction system shown in Fig. 1 is designed for an inline 6-cylinder engine. The invention is in principle not limited to this.

Die Kunststoffsauganlage 1 besteht aus dem Luftsammler 2 und den Saugrohren 3 bis 8, die sich an einer Längsseite des Luftsammlers 2 anschließen und zu einer gemeinsamen Flanschleiste 9 als getrennte, räumlich gewundene Rohre verlaufen. Auf der der Anschlußseite der Saugrohre gegen­ überliegenden Seite des Luftsammlers 2 ist das Drossel­ klappenstutzengehäuse 10 angeordnet.The plastic suction system 1 consists of the air collector 2 and the suction pipes 3 to 8 , which connect to one long side of the air collector 2 and run to a common flange strip 9 as separate, spatially wound pipes. On the connection side of the intake manifolds opposite side of the air collector 2 , the throttle valve body housing 10 is arranged.

Allgemein besteht der Luftsammler 2 sowie die angeschlos­ senen Saugrohre 3 bis 8 aus zwei Halbschalen, wobei an einer Halbschale noch die Flanschleiste 9 angeformt ist. Beide Halbschalen werden in Spritzgußtechnik hergestellt.In general, the air collector 2 and the connected suction pipes 3 to 8 consist of two half-shells, the flange strip 9 being formed on a half-shell. Both half shells are manufactured using injection molding technology.

Zum Verbinden der beiden Halbschalen weisen beide umlau­ fende Verbindungsflansche 11, 12 auf. Über diese Verbin­ dungsflansche werden die beiden Halbschalen mittels eines geeigneten Schweißverfahrens, insbesondere durch Reib­ schweißen, miteinander verbunden.To connect the two half-shells, both have umlau fende connecting flanges 11 , 12 . About this connec tion flanges, the two half-shells are connected to one another by means of a suitable welding process, in particular by friction welding.

Anschließend wird die so hergestellte Sauganlage in einer weiteren Spritzgußmaschine eingelegt. In dieser Spritz­ gußmaschine werden die Verbindungsflansche 11, 12 um den Luftsammler 2 von Verbindungselementen 13 bis 18 umman­ telt. Das Verbindungselement 13 umfaßt die Schmalseiten des Luftsammlers sowie die den Saugrohren gegenüberlie­ gende Längsseite. Gleichzeitig wird das Drosselklappen­ stutzengehäuse aus dem gleichen Material wie die Verbindungselemente mit angespritzt. Er ist also mit dem Verbindungselement 13 einstückig ausgebildet. Zum gas- und flüssigkeitsdichten Anschluß an den Luftsammler weist dieser entsprechend ausgebildete Flanschseiten auf, die vom Material des Drosselklappenstutzengehäuses umgriffen werden. Die Verbindungselemente 14 bis 18 sind jeweils separat und nicht untereinander verbunden, werden aber in dem selben Arbeitsgang hergestellt.The suction system thus produced is then placed in a further injection molding machine. In this injection molding machine, the connecting flanges 11 , 12 around the air collector 2 of connecting elements 13 to 18 are coated. The connecting element 13 comprises the narrow sides of the air collector and the longitudinal side opposite the suction pipes. At the same time, the throttle body is molded from the same material as the connecting elements. It is therefore formed in one piece with the connecting element 13 . For gas and liquid-tight connection to the air collector, the air collector has correspondingly designed flange sides which are encompassed by the material of the throttle valve housing. The connecting elements 14 to 18 are each separately and not connected to one another, but are produced in the same operation.

In Fig. 2 ist ein Querschnitt durch den Luftsammler auf Höhe des Drosselklappenstutzengehäuses 10 dargestellt. Hier ist ersichtlich, wie das Drosselklappenstutzenge­ häuse an den beiden den Luftsammler bildenden Halbschalen befestigt ist. Auch ist gleichzeitig ein Schnitt durch das Verbindungselement 16 dargestellt. Hier erkennt man, daß das Verbindungselement 16 klammerartig im Querschnitt aufgebaut ist, wozu die Verbindungsflansche 11, 12 ein Profil mit Hinterschneidungen aufweisen.In Fig. 2 is a cross section through the air manifold at the level of the throttle-valve housing 10. Here it can be seen how the throttle body is attached to the two half shells forming the air collector. A section through the connecting element 16 is also shown at the same time. Here you can see that the connecting element 16 is constructed like a clamp in cross-section, for which purpose the connecting flanges 11 , 12 have a profile with undercuts.

In Fig. 3 ist ein Schnitt durch die Saugrohre 7 und 8 gemäß Schnittlinie III-III dargestellt. Hier ist eben­ falls ganz deutlich die Anordnung aus zwei Halbschalen erkennbar sowie der Aufbau der Verbindungsflansche 11, 12 und der Querschnitt der Verbindungselemente 3 und 18.In Fig. 3 a section through the suction pipes 7 and 8 is shown on the section line III-III. The arrangement of two half shells as well as the structure of the connecting flanges 11 , 12 and the cross section of the connecting elements 3 and 18 can be clearly seen here.
