Title:
スリーブおよび短くされた筒状ジャケットを備える触媒支持体
Document Type and Number:
Japanese Patent JP4549607
Kind Code:
B2
Abstract:
A catalyst carrier body includes a honeycomb body having sheet-metal layers and an axial extent. The sheet-metal layers are at least partly structured in such a way that the honeycomb body has passages through which an exhaust gas can flow. The sheet-metal layers of the honeycomb body have end regions lying radially outwardly. A tubular jacket has an edge and an axial span shorter than the axial extent of the honeycomb body. The tubular jacket is connected to the honeycomb body in at least one axial partial-region by a joining technique. A sleeve has an axial length shorter than the axial extent of the honeycomb body and is disposed on an outer region of the honeycomb body, in the vicinity of an end surface. The sleeve has an inner shell surface connected by a joining technique to the end regions of the sheet-metal layers at the end surfaces. The honeycomb body projects beyond an edge of the tubular jacket in a projecting section surrounded by the sleeve. In this way, stresses between the honeycomb body and the tubular jacket are avoided even with high thermal loads on the catalyst carrier body. A catalytic converter having the catalyst carrier body is also provided.
