Description

Die Erfindung betrifft Sammelflansche zur Montage am Zylinderkopf von Verbrennungsmotoren, umfassend ein Sammelgehäuse, einen Rohranschlussflansch und je Zylinder einen Einzelflansch mit Befestigungseinrichtung.The The invention relates to collection flanges for mounting on the cylinder head of Internal combustion engines, comprising a collecting housing, a pipe connection flange and each cylinder a single flange with fastening device.

Sammelflansche zur Befestigung am Zylinderkopf von Verbrennungsmotoren umfassen ein Sammelgehäuse, welches die aus den Zylindern austretenden heißen Abgase zu einem Rohranschlussflansch leitet, wo weitere Abgasbehandlungselemente befestigt sind. Die Befestigung des Sammelflansches am Zylinderkopf erfolgt mit Hilfe von Flanschen, die mit Hilfe von Stehbolzen und Muttern oder mit Hilfe von Schrauben montiert werden. Zwischen Zylinderkopf und Flansch befindet sich eine Dichtung.Sammelflansche for attachment to the cylinder head of internal combustion engines a collection housing, which exhausts the hot exhaust gases from the cylinders to a pipe connection flange directs where further exhaust treatment elements are attached. The Mounting of the collecting flange on the cylinder head is done with help of flanges, with the help of studs and nuts or with Help to be mounted by screws. Between cylinder head and flange there is a seal.

Das Sammelgehäuse wird durch die heißen Abgase auf Temperaturen bis zu ca. 900° C aufgeheizt, wodurch es sich entsprechend ausdehnt. Die Zylinderbefestigungsflansche dagegen erreichen maximal Temperaturen von ca. 120° C, da sie großflächig mit dem Zylinderkopf verbunden sind, der seinerseits wassergekühlt ist. Durch die extremen Temperaturdifferenzen entstehen entsprechende Ausdehnungsdifferenzen, die ausgeglichen werden müssen. Einen Teil der Ausdehnungsdifferenzen nimmt das Sammelgehäuse auf. Der andere Teil der Ausdehnungsdifferenzen wird durch Gleiten der Zylinderkopfbefestigungsflansche auf der Dichtung ausgeglichen.The collecting case is due to the hot exhaust gases to temperatures up to approx. 900 ° C heated, whereby it expands accordingly. The cylinder mounting flanges By contrast, temperatures reach a maximum of about 120 ° C, since they with a large area connected to the cylinder head, which in turn is water cooled. Due to the extreme temperature differences arise corresponding Expansion differences that need to be compensated. a Part of the expansion differences takes on the collection housing. The other part of the expansion differences is by sliding the Cylinder head mounting flanges balanced on the gasket.

Es versteht sich, dass der Ausdehnungsausgleich dann optimal ist, wenn die Zylinderkopfbefestigungsflansche als Einzelflansche ausgebildet sind. Herstellung und Montage von Sammelflanschen mit Einzelflanschen ist jedoch sehr umständlich. Jeder Einzelflansch muss einzeln gehandhabt werden. Jeder Einzelflansch muss zur Montage an den Krümmerrohren in eine Montagevorrichtung eingelegt werden, wobei durch geeignete Maßnahmen sichergestellt werden muss, dass beim Einlegen der drei, vier, fünf usw. Einzelflansche keine Verwechslungen passieren, die den Sammelflansch zum Ausschuss machen würden. Dies ist unbefriedigend.It It is understood that the expansion compensation is optimal when the cylinder head mounting flanges formed as a single flanges are. Production and assembly of collecting flanges with single flanges However, it is very complicated. Each individual flange must be handled individually. Each individual flange must be mounted on the manifold pipes be inserted into a mounting device, wherein by suitable activities It must be ensured that when inserting the three, four, five etc. Single flanges do not pass any confusions that the collection flange to the committee. This is unsatisfactory.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, Sammelflansche zur Montage am Zylinderkopf von Verbrennungsmotoren derart auszugestalten, dass sie einfach, schnell und sicher gehandhabt und montiert werden können, ohne die erwünschten Eigenschaften zum Ausgleich von thermischen Ausdehnungsdifferenzen zu verlieren.Of the present invention is based on the object, collection flanges for the assembly on the cylinder head of internal combustion engines in such a way, that they are easy, quick and safe to handle and assemble can, without the desired Properties to compensate for thermal expansion differences to lose.

Diese Aufgabe wird dadurch gelöst, dass benachbarte Einzelflansche über Dehnbögen verbunden sind.These Task is solved by that adjacent single flanges over Dehnbögen are connected.

Der vorliegenden Erfindung liegt das Prinzip zugrunde, die Einzelflansche über Dehnbögen zu verbinden, die den thermischen Ausdehnungsbewegungen elastisch nachgeben, gleichzeitig jedoch eine Handhabung vergleichbar einem herkömmlichen Blechflansch erlauben. Maßnahmen, um eine Verwechslung der Einzelflansche zu verhindern, entfallen völlig.Of the The present invention is based on the principle of connecting the individual flanges via expansion bends. which yield elastically to the thermal expansion movements, at the same time however, allow handling comparable to a conventional sheet metal flange. Activities, to avoid confusion of the individual flanges omitted completely.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind die Bögen mit den Einzelflanschen einstückig. Dies erlaubt die Herstellung mit einem einzigen Stanzhub, das heißt in der kürzestmöglichen Zeit.According to one advantageous embodiment of the invention, the sheets with the single flanges in one piece. This allows the production with a single punching stroke, that is in the shortest possible Time.

Anhand der Zeichnung soll die Erfindung in Form von Ausführungsbeispielen näher erläutert werden. Es zeigenBased the drawing is intended to illustrate the invention in the form of embodiments be explained in more detail. Show it
