Supporting structure with an at least partially as a resonance cavity structure hollow space of a structure which is used, the chamber and the motor vehicle

摘要

The invention relates to a supporting structure (s) having an at least partially used as a resonance cavity structure cavity (kh) of a structure chamber (k). It is characterized in that the structure chamber (k) in the form of an elongate hollow body, which is open on one side with an open structure chamber along end (i) and a closed structure chamber along end (i) is formed, at the open structure chamber along end (i) an introduction chamber (10) is formed of an introduction cavity (11) is formed, into which the structure cavity (kh) of the structure chamber (k) and a cavity (15) of a sound generating chamber (16) open, whereby a distance (13) to an opposite introduction surface (12) and the open structure chamber along end (i) 20 - 40 mm, and the closed structure chamber along end (lc) with a closing wall (c) is closed.
