Patent DE-19858634-A1 (DE)
Title: Flexschlauch
Inventor: PAPE KARL
IPC: F16L27/111
Filed: 1998-12-18
Abstract: Ein erfindungsgemäßer Flexschlauch, der insbesondere für eine Abgasleitung eines Verbrennungsmotors bei einem Kraftfahrzeug vorgesehen ist, weist zumindest einen Wellenbalg 10, eine Außenumflechtung 30 und bevorzugt zwei Endhülsen auf, die an den beiden Enden des Flexschlauches den Wellenbalg 10 und die Außenumflechtung 30 fassen und halten, wobei die Außenumflechtung 30 eine Wellung bzw. Ondulierung aufweist. Durch die Wellen der Ondulierung der Außenumflechtung 30 wird an mehreren Stellen eine Vorspannung zwischen der Außenumflechtung 30 und dem Wellenbalg 10 erzeugt, die zur Verhinderung von Rasselgeräuschen bei Schwingungen bzw. Vibrationen dient. Im Ergebnis wird eine Resonanzbedämpfung des Wellenbalgs 10 durch Reibung zwischen diesen Bauteilen bewirkt. Die durch die Wellung erzeugte Vorspannung ist dabei im allgemeinen gering und hängt von unterschiedlichen Parametern, wie beispielsweise den geometrischen Abmessungen der Elemente des Flexschlauches, den eingesetzten Materialien und den zu absorbierenden bzw. zu dämpfenden Schwingungen ab.

The side surfaces (13) of the clamp anchors (7,8) are parallel to each other, and the clamp anchors (7,8) have an additional locking action through a swallowtail or cut-back structure. The ends of the clamp anchors (7,8) are truncated, pref. at right angles to their side surfaces (13), with aligned end surfaces (14). The ends of the clamp anchors (7,8) can be rounded. The hub ring (2) is of a metal or plastics material. The support ring (3) is of a polymer material with a Shore hardness of  <= 98 and pref.  <= 96. The thickness (S) of the bridge section (4) is  <= 4 mm and is pref. 2.5 mm.
