Abstract

Um bei einem Katalysatorgehäuse einen besseren Strömungsverlauf im Trichterbereich zu erhalten werden die Eingangs- und Ausgangstrichter (2; 3) mit ihren Großdurchmessern an Anbindungsschrägen (11; 12) des Katalysator-Wickelbleches (1) angesetzt und verschweißt. Die Trichter (2; 3) werden aus einem Rohrstück durch Aufweiten des einen Endes und Einziehen des anderen Endes hergestellt. Hierdurch erhält man eine deutliche Gewichtsverringerung gegenüber aus Blechplatinen tiefgezogenen Trichtern.

Figure 00000001
In order to obtain a better flow profile in the funnel area in the case of a catalytic converter, the inlet and outlet funnels (2; 3) with their large diameters are attached and welded to connecting bevels (11; 12) of the catalytic converter winding plate (1). The funnels (2; 3) are made from a piece of pipe by expanding one end and drawing in the other end. This results in a significant reduction in weight compared to funnels drawn from sheet metal blanks.
