Description
Die Erfindung betrifft Flansche zur Befestigung eines Auspuffkrümmers an einem Motorblock gemäß dem Oberbegriff des Anspruchs 1.The invention relates to flanges for attaching an exhaust manifold to one Engine block according to the preamble of claim 1.
Auspuffkrümmer, die die aus den Zylinderauslässen des Motorblocks austretenden heißen Abgase sammeln und zur Abgasanlage, bestehend aus Abgasrohren, katalytischem Konverter und Schalldämpfer, führen, wurden ursprünglich als Gußteile hergestellt. Man vergleiche beispielsweise die US 28 47 819. Dabei bildet der Flansch, mit dessen Hilfe der Auspuffkrümmer an dem Motorblock angeschraubt wird, die größten Probleme. Zunächst einmal muß der Flansch gasdicht befestigt werden können. Weiterhin . schreibt der moderne Motorenbau bestimmte Formen und Dicken der Flansche vor, was beim Gießen zu einem hohen finanziellen Aufwand führt.Exhaust manifold that exits from the cylinder outlets of the engine block collect hot exhaust gases and to the exhaust system, consisting of exhaust pipes, catalytic converter and muffler, were originally made as castings manufactured. Compare for example US 28 47 819. The flange forms with whose help the exhaust manifold is screwed to the engine block, the largest Problems. First of all, the flange must be able to be attached in a gas-tight manner. Farther , modern engine construction dictates certain shapes and thicknesses of the flanges what results in a high financial outlay when casting.
Aus diesem Grund werden zunehmend Rohrkrümmer verwendet. Diese bestehen aus Krümmerrohren geeigneter Länge und Form, die an einen Flansch angeschweißt werden.For this reason, pipe elbows are increasingly used. These consist of Elbow pipes of suitable length and shape, which are welded to a flange.
Auch an die Flansche, mit deren Hilfe die Auspuffkrümmer an den Motorblock geschraubt werden, werden besondere Anforderungen gestellt. Beispielsweise sollen die Flansche gasdicht sein und eine hohe Eigensteifigkeit besitzen. Probleme bereiten auch die hohen Temperaturen und die damit verbundenen thermischen Ausdehnungsdifferenzen. Man vergleiche diesbezüglich die DE-OS 15 76 357, die für jeden Zylinderauslaß einen eigenen kleinen Flansch vorsieht.Also on the flanges, with the help of which the exhaust manifold is screwed to the engine block special requirements are made. For example, the flanges be gastight and have a high inherent rigidity. The high ones also cause problems Temperatures and the associated thermal expansion differences. you compare in this respect DE-OS 15 76 357, one for each cylinder outlet has its own small flange.
Die DE 31 29 351 C2 offenbart einen Flansch, der in Dickenrichtung geteilt ausgebildet ist. Die ankommende Rohrleitung des Krümmers wird nur an dem einen Flanschteil festgeschweißt Dieses Flanschteil wird seinerseits dann mit dem anderen Flanschteil verschweißt. Dadurch sollen infolge der Wärmebeanspruchung auftretende Kräfte besser aufgefangen werden. Auch hier ist für jeden Zylinderauslaß ein eigener, kleinflächiger Flansch vorgesehen. DE 31 29 351 C2 discloses a flange which is divided in the thickness direction is. The incoming pipe of the elbow is only on one flange part welded this flange part is then in turn with the other flange part welded. As a result, forces occurring as a result of the thermal stress should be better to be caught. Here, too, there is a separate, small area for each cylinder outlet Flange provided.
Die EP 0 178 430 B1 schließlich offenbart einen Auspuffkrümmer mit einem Flansch, der aus vier relativ dünnen Blechplatinen zusammengesetzt ist, die wenigstens teilweise aus Edelstahl bestehen können. Die Blechplatinen sind einzeln gestanzt, werden mit Hilfe von Paßbohrungen und Paßstiften paßgenau gestapelt und schließlich hart gelötet. Die oberste Blechplatine ist mit einem Durchzug versehen, in den ein Krümmerrohr eingeschweißt werden kann. Dieser Flansch ist für zwei Zylinderauslässe vorgesehen.Finally, EP 0 178 430 B1 discloses an exhaust manifold with a flange that is composed of four relatively thin sheet metal plates, which at least partially Stainless steel can exist. The metal sheets are punched individually, are made with the help of Dowel holes and dowel pins stacked exactly and finally brazed. The top sheet metal plate is provided with a passage in which a manifold pipe can be welded. This flange is intended for two cylinder outlets.
Es versteht sich, daß es inzwischen auch gelungen ist, auch aus Blechplatinen zusammengesetzte Flansche herzustellen, die sämtliche Zylinderauslässe, beispielsweise vier bei einem Vierzylindermotor, in einem Stück abzudecken. Abgaskrümmer mit solchen einstückigen Flanschen müssen jedoch sehr steif ausgeführt werden, damit die aus den Temperaturdifferenzen der verschiedenen Einzelteile resultierenden Wärmedehnungen aufgefangen werden können, ohne daß der Flansch undicht wird. Steif bedeutet dabei schwer.It goes without saying that it has now also succeeded, even from sheet metal to produce composite flanges that cover all cylinder outlets, for example four with a four-cylinder engine to cover in one piece. Exhaust manifold with such one-piece flanges must be made very stiff, so that from the Temperature differences between the various individual parts resulting from thermal expansion can be collected without the flange leaking. Stiff means heavy.
Eine andere Lösung dieses Problems ist Gegenstand der DE 296 15 840 U. Dieser Flansch besteht aus einem einzigen, tiefgezogenen Blech.Another solution to this problem is the subject of DE 296 15 840 U. This Flange consists of a single, deep-drawn sheet.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen aus mehreren Blechplatinen zusammengesetzten Flansch anzugeben, der die Vorteile der bekannten Konstruktionen miteinander verbindetThe present invention has for its object one of several Sheet metal composite flange indicate the advantages of the known Constructions
Diese Aufgabe wird gelöst durch einen Flansch mit den Merkmalen des Anspruchs 1.This object is achieved by a flange with the features of claim 1.
Dank der vorliegenden Erfindung können einfache Blechplatinen verwendet werden, die in
bekannter Technik gestanzt und anschließend miteinander verbunden werden, z. B. durch
Löten, Schweißen oder mechanische Verbindung. Da der Flansch auch aus mehreren
Einzelteilen besteht, sind Relativbewegungen der einzelnen Teilflansche bzw.
Krümmerrohre zueinander möglich. Die Montagemöglichkeiten sind variabel. Bei der
Krümmergestaltung bestehen größere Freiheitsgrade, da an den innenliegenden
Zylindern nicht alle Schrauberfreigänge erforderlich sind. Sofern z. B. für einen
Vierzylindermotor zwei einzelne Krümmerpaare vorgesehen werden, z. B. Zylinder 1 + 4
ein Krümmerpaar und Zylinder 2 + 3 ein Krümmerpaar, kann eines der beiden
Krümmerpaare bis auf die Überlappstellen komplett montiert werden. Die Schrauben der
schon montierten Krümmer können dann von den Rohren der anschließend zu
montierenden Krümmer verdeckt werden. Es ergibt sich gegenüber Einzelflanschen mit
ungleichmäßig verteilten Verschraubungspositionen bei der erfindungsgemäßen Lösung
ein relativ gleichmäßiges Verschraubungsbild, was Voraussetzung für eine gute
Gasdichtigkeit ist.Thanks to the present invention, simple sheet metal plates can be used, which in
known technology punched and then connected together, for. B. by
Soldering, welding or mechanical connection. Since the flange also consists of several
Individual parts, there are relative movements of the individual partial flanges or
Manifold pipes possible to each other. The mounting options are variable. In the
There is a greater degree of freedom in the design of the manifold, since it is on the inside
Cylinders not all screwdriver clearances are required. If z. B. for one
Four cylinder two individual manifold pairs are provided, e.g. B. Cylinder 1 + 4
a pair of manifolds and
Gemäß einer vorteilhaften Weiterbildung der Erfindung kann das Gleiten der Berührungsflächen durch eine geeignete Beschichtung verbessert werden.According to an advantageous development of the invention, the sliding of the Contact surfaces can be improved by a suitable coating.
An den Überlappungsstellen ist es möglich, in der 1. Platine eine enge Befestigungsöffnung zur genauen Positionierung und in der 2. Platine eine größere Befestigungsöffnung vorzusehen, die die Relativbewegung ermöglicht.At the overlap points it is possible to have a tight one in the 1st board Fastening opening for precise positioning and a larger one in the 2nd board Provide mounting opening that allows the relative movement.
