"Verbindungselement""Connecting element"
Die Erfindung betrifft eine Einrichtung z.B. zur Abgasrückführung bei Verbrennungsmotoren mit einer eine Gehäusedurchbrechung durchdringenden metallischen Leitung, die über ein Verbindungselement mit einem Gehäuse verbunden ist.The invention relates to a device, e.g. for exhaust gas recirculation in internal combustion engines, with a metallic line penetrating a housing opening, which is connected to a housing via a connecting element.
Im bekannten Fall führt die Leitung das Abgas vom Sammelrohr zu einem Gehäuse, das den Ansaugkanal enthält, zurück. Hier wird das zurückgeführte Abgas der Ansaugluft beigemischt. Die Leitung ist mit dem Gehäuse über ein Verbindungselement verbunden.In the known case, the line returns the exhaust gas from the manifold to a housing that contains the intake duct. Here, the returned exhaust gas is mixed with the intake air. The line is connected to the housing via a connecting element.
Das Verbindungselement, das aus einem Topf mit z.B. U-förmigem Wandungsquerschnitt besteht, ist einerseits über einen Flansch mit dem Gehäuse und andererseits mit der Leitung verbunden.The connecting element, which consists of a pot with a U-shaped wall cross-section, is connected to the housing on the one hand via a flange and to the line on the other hand.
Das Verbindungselement hat die Aufgabe, die an der Leitung abgenommene Temperatur über seine U-förmige Oberfläche so weit herabzusetzen, daß die Temperatur für die Befestigung des Verbindungselements mit dem Gehäuse unschädlich ist.The connecting element has the task of reducing the temperature taken from the line via its U-shaped surface to such an extent that the temperature is not harmful for the fastening of the connecting element to the housing.
Das bekannte Verbindungselement läßt beim Einbau der Leitung in das Gehäuse keinerlei Montageausgleich zu und entkoppelt das Gehäuse und damit die Verbindungsstelle zum Gehäuse nicht von Bewegungen und Schwingungen der Leitung, so daß eine starke Beanspruchung der Dichtung auftritt.The known connecting element does not allow any assembly compensation when installing the cable in the housing and does not decouple the housing and thus the connection point to the housing from movements and vibrations of the cable, so that the seal is subjected to great stress.

AufgabeTask
Das Verbindungselement soll so weiterentwickelt werden, daß es neben der Funktion des Temperaturabbaus zwischen Leitung und Gehäuse gleichzeitig den Montageausgieich beim Einbau der Leitung in das Gehäuse ermögEcht und Schwingungen und darüber hinaus Bewegungen der Leitung von der Verbindungsstelle zum Gehäuse und vom Gehäuse entkoppelt.The connecting element should be further developed so that, in addition to the function of reducing the temperature between the cable and the housing, it simultaneously enables assembly compensation when installing the cable in the housing and decouples vibrations and, in addition, movements of the cable from the connection point to the housing and from the housing.
LösungSolution
Diese Aufgabe wird von einem Metallbalg 5 gelöst, der den erforderlichen Temperaturabbau über seine Wellung ermöglicht, zugleich aber sowohl Montageausgleich und Spannungsabbau beim Einbau und im Betrieb wie auch Entkoppelung von Bewegungen und Schwingungen der Leitung 1 gegenüber dem Gehäuse 4 ermöglicht und damit die Verbindungsstelle 3 entlastet und damit eine einfachere Ausführung der Dichtung erlaubt.This task is solved by a metal bellows 5, which enables the required temperature reduction via its corrugation, but at the same time enables assembly compensation and stress reduction during installation and operation as well as decoupling of movements and vibrations of the line 1 from the housing 4, thus relieving the connection point 3 and thus allowing a simpler design of the seal.
