Abstract

An air manifold (1) for an internal combustion engine comprises a housing (2) and intake connections (3) arranged in this, which are assembled from half-shells (4, 5), thereby making it easy to manufacture. Inside the housing the halves of the intake connection are held together by simple fastening means, for example tongue-groove connection (6). The housing (2) is manufactured by the blowing process and encompasses the ends of the intake connections (3), in each case in a positively interlocking manner and forming a seal immediately in front of the associated fixing flange (9). <IMAGE>

Description

Luft sammler für einen VerbrennungsmotorAir collector for an internal combustion engine

Die Erfindung betrifft einen Luftsammler für Verbrennungsmotoren nach dem Oberbegriff des Anspruchs 1.The invention relates to an air collector for internal combustion engines the preamble of claim 1.

Ein derartiger Luftsammler ist bekannt aus der DE-OS 32 19 699 und der DE-OS 25 27 774. Die Ansaugstutzen im Innern des Gehäuses dieser Luftsammler sind jeweils aus einem Stück gefertigt, so daß einerseits besondere Maßnahme getroffen werden müssen, um diese Ansaugstutzen im Gehäuse des Luftsammlers unterzubringen, und andererseits die Herstellung der Ansaugstutzen komplizierte Vorrichtungen und aufwendige Verfahren erfordert.Such an air collector is known from DE-OS 32 19 699 and DE-OS 25 27 774. The intake manifold inside the housing of this air collector are each made of one piece, so that on the one hand special measures are taken need to be in order to accommodate these intake ports in the housing of the air collector, and on the other hand, the manufacture of the intake manifold complicated devices and requires complex procedures.

Hiervon ausgehend liest der erfindung die Bufgabe zugrunde den gattunsgemäßen Luftsammler mit seinem im Innern des Gehäuses angeordneten Ansaugstutzen auf einfachere Weise und mit erheblicher Kostenersparnis herzustellen. Insbesondere soll die Herstellung des Ansaugstutzens vereinfacht sowie die Befestigung und Verbindung mit dem Gehäuse bei dessen Herstellung ermöglicht werden.Proceeding from this, the invention reads the task based on the generic Air collector with its intake manifold located inside the housing on a simpler one Way and with considerable cost savings. In particular, the production the intake manifold simplified as well as the attachment and connection to the housing are made possible in its manufacture.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1.This problem is solved by the characterizing features of the claim 1.

In den Unteransprüchen sind weitere merkmale eines derartigen Luftsammlers nach der Erfindung enthalten.The subclaims contain further features of such an air collector included according to the invention.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles mit Bezugnahme auf die Zeichnungen näher erläutert.The invention is explained below using an exemplary embodiment explained in more detail with reference to the drawings.

Es zeigt Fig. 1 die Draufsicht eines erfindungsgemäßen Luftsammlers teilweise im Schnitt Fig. 2 die Ansicht II-Ir gerräß Fig. 1 Fig. 3 eine Seitenansicht des Luftsammlers, teilweise im Schnitt Ein Luftsammler 1 für einen 4-Zylinder-Verbrennungsmotor besteht aus einem Gehäuse 2 und vier im Inneren des Gehäuses 2 an7je0rd2tfl Ansaugstutzen 3. Jeder Ansaugstutzen 3 besteht aus zwei Halbschalen 4,6 , di innerhalb des Gehäuses 2 durch eine Nut-Feder-Verbindung 6 zusammengehalten werden. Die in das Innere des Gehäuses 2 ragenden Enden 7 des Ansaugstutzens 3 sind trichterförmig aufgeweitet. Die Halbschale 5 des Ansaugstutzens 3 ist an ihrem motorblockseitigen Ende über ein kurzes Rohrstück 8 einstückig mit einem Befestigungsflansch 9 verbunden. Die im SpritzgußxJervahrnn allc Kunststoff hergestellten zusammenhängenden Ansaugstutzen bestehen aus drei Einzelteilen, von denen zwei die gleiche Form aufweisen und jeweils zwei Halbschalen 4 von zwei nebeneinanderliegenden Ansaugstutzenhälften umfassen. Die Teile können auf einfache Weise ohne Kerne hergestellt werden.1 shows a top view of an air collector according to the invention partially in section, FIG. 2, the view II-Ir, FIG. 1, FIG. 3, a side view of the air collector, partly in section An air collector 1 for a 4-cylinder internal combustion engine consists of a housing 2 and four inside the housing 2 an7je0rd2tfl intake manifold 3. Each intake 3 consists of two half-shells 4, 6, ie inside the housing 2 are held together by a tongue and groove connection 6. The inside of the Housing 2 protruding ends 7 of the intake port 3 are widened in a funnel shape. The half-shell 5 of the intake 3 is over at its engine block-side end a short pipe section 8 connected in one piece to a fastening flange 9. the In the injection molding process, all plastic-made coherent intake manifolds consist of three individual parts, two of which have the same shape and each include two half-shells 4 of two adjacent intake port halves. The parts can easily be made without cores.

Das dritte Einzelteil umfaßt alle vier Befestigunqsflansche 9 mit den angeformten kurzen Rohrstücken 8 sowie uler Halbschalen 5 aller vier Ansaugstutzenhälften.The third item includes all four mounting flanges 9 with the molded short pipe pieces 8 and uler half-shells 5 of all four intake port halves.

Das mit einem Lufteinlaßstutzen 10 versehene Gehäuse 2 wird im Blasverfahren hergestellt und umfaßt bei der Herstellung unmittelbar vor den Befestigungsflanschen 9 die Rohr stücke 8 und die Enden der Ansaugstutzen 3 dichtend und formschlüssig 11.The housing 2, which is provided with an air inlet connector 10, is blown using a blow molding process manufactured and includes in manufacture immediately before the mounting flanges 9 the pipe pieces 8 and the ends of the intake 3 sealing and form-fitting 11.

Durch einen derartig hergestellten Luftsammler 1 ist erreicht worden, daß die Einzelteile auf einfache und kostengünstige Weise heraestellt werden können, wobei insbesondere auch die Zusammenfügung der Halbschalen 4,5 sehr einfach und nicht unbedingt luftdicht erfolgen kann, da diese in diesen Bereichen innerhalb des Gehäuses 2 liegen.An air collector 1 manufactured in this way has achieved that the items can be manufactured in a simple and inexpensive manner, in particular, the assembly of the half-shells 4.5 and very simple cannot necessarily be made airtight, as these are within these areas of the housing 2 lie.
