Abstract

Ein Abgasschalldämpfer dieser Art besteht aus einer Innenkonstruktion, die z.B. ein den Gasstrom führendes zentrales Rohrsystem (10) umfaßt. und einem im wesentli­ chen rohrförmigen Außengehäuse (20; 40) aus Aluminium bzw. einer Aluminiumlegierung. An exhaust silencer of this type consists of one Internal construction, e.g. a leading gas stream central pipe system (10) comprises. and one essentially Chen tubular outer housing (20; 40) made of aluminum or an aluminum alloy.

Um einen Abgasschalldämpfer zu schaffen, der sich sowohl der Vorteile des Werkstoffes Aluminium als auch der Vorteile der bekannten oberflächengeschützten Stahlwerk­ stoffe bedient und Kosten- und Gewichtseinsparungen bei gleichzeitig erhöhter Lebenserwartung erzielt, ist die Innen­ konstruktion (z.B. 10) als allein tragendes Konstruktionsele­ ment ausgebildet, während das aus Aluminium bzw. einer Aluminiumlegierung bestehende Außengehäuse (20; 40) eine ausschließlich den Funnktionsraum des Abgasschall­ dämpfers abgrenzende Hülle bildet, die sich auf der tragen­ den Innenkonstruktion (z.B. 10) abstützt. To create an exhaust silencer that is both the advantages of aluminum as a material Advantages of the well-known surface-protected steel mill fabrics served and cost and weight savings achieved at the same time increased life expectancy, is the interior construction (e.g. 10) as a single structural element ment trained, while the aluminum or one Aluminum alloy existing outer housing (20; 40) one exclusively the functional area of the exhaust sound damper delimiting envelope forms, which wear on the supports the inner construction (e.g. 10).

Ein besonders günstiges Verfahren zur Herstellung eines doppelschichtigen Außengehäuses aus zwei verschiedenen Aluminiumlegierungen besteht darin, daß die Doppelschicht zweier Al-Legierungen durch Verpressen (Kaltfließ­ pressen) einer aus einem plattierten Material gefertigten Butze erzeugt wird. A particularly inexpensive method for producing a double-layer outer casing made of two different Aluminum alloys consist of the double layer two Al alloys by pressing (cold flow press) one made of a clad material Butze is generated.
