WASTE CATALYTIC CONVERTER WITH A BEARING COMPENSATING DILATIONS

摘要

A honeycomb assembly includes a honeycomb body which is held in a housing and has an outer surface, especially in an exhaust gas system of an internal combustion engine. The honeycomb body has an axial length and the outer surface is surrounded by at least one metal sheet which is bent in sections into a plurality of layers that can move radially towards each other between the outer surface and the housing, forming overhanging bulges of the metal sheet in circumferential direction. The bulges extend forwards and backwards in the circumferential direction. The honeycomb body held in the housing can expand thermally in an almost unimpeded manner relative to the housing, so that a durable fixation of the honeycomb body in the housing, especially in the housing of an exhaust gas system of an internal combustion engine, can be obtained. The assembly is particularly useful for honeycomb bodies with a high channel density of 800 cpsi and a sheet metal thickness of less than 0.025 mm.
