Abstract
延在方向(4)を有する排気管(3)と、
少なくともセラミックまたは押出された材料を含むハニカム体(5)と、
排気管(3)とハニカム体(5)との間に少なくとも部分的に配置される少なくとも1つの金属製の繊維ウェブ(6)とを含み、
この装置においては、異なる機能を有する少なくとも2つのゾーン(7、8、9)が延在方向(4)において少なくとも1つの繊維ウェブ(6)によって形成され、少なくとも1つの第1のゾーン(7)はハニカム体(5)を取付けるための手段を有し、少なくとも1つのさらなるゾーン(8、9)は、断熱のための手段とガスに関し封鎖を形成するための手段とからなる群から選択される手段を有することを特徴とする、装置(1)。
Description
る消光温度(Anspringtemperatur)に達する。さらに、この装置は、安価であり、さらに、連続製造において製造が簡単であるよう意図される。
− 延在方向を有する排気管と、
− 少なくともセラミックまたは押出された材料を含むハニカム体と、
− 排気管とハニカム体との間に少なくとも部分的に配置される少なくとも1つの金属製の繊維ウェブとを含む。
ましくは、「エンドレス」繊維として設計され、編み合わされることにより、ある種の編まれたワイヤ繊維を形成する。繊維ウェブがある種の不規則な繊維層として構成される場合、それは、好ましくは、平均繊維長を5mm〜25mmの範囲に有する繊維を含む。さらに、繊維ウェブは実質的に滑らかであるかまたは少なくとも部分的に構造化されてもよいことに注目されたく、その場合には、波形構造が、特に、その構造を、編まれたワイヤ繊維として用いる際に、好ましい。
− 第1のゾーンと比較して、異なる種類の繊維、
− 第1のゾーンと比較して、異なる構成の繊維、
− さらなる充填材料、
− さらなるガス不透過性バリア要素
のうちの少なくとも1つにより与えられる場合、特に有利である。
排気ガスがその上へと流れる、繊維ウェブの前側部(第1のゾーン)はたとえば60〜80%の範囲のより高い空孔率の金属製繊維ウェブを含む。それは、ハニカム体の径方向のみならず軸方向の固定または支持のためにも働く。
2mmの繊維径を有する「エンドレス」繊維を有する。したがって、繊維ウェブ6は構造28を保持する内在的な安定性を有する。繊維ウェブ6に封鎖機能を設けるため、閉鎖29を構造28において(両側に)組入れることが可能である。構造化された繊維ウェブ6の接触の領域においての、ハニカム体5への端部30を介しての圧力ピークを回避するため、圧力分散部材27が存在する。圧力分散部材27は、たとえば、滑らかな不規則な繊維層を伴って形成されてもよい。
保護的要素、23 突起、24 ばね要素、25 通路壁、26 外側壁、27 圧力分散部材、28 構造、29 閉鎖、30 端部。
