US 6,316,384 B1 · Honeycomb body configuration with support sections

Abstract

A honeycomb body configuration includes a metal housing accommodating a honeycomb body having a plurality of channels separated from one another by dividing walls. The honeycomb body has varying radial strength along its periphery. A compensation layer is disposed at least in partial regions of the periphery between the housing and the honeycomb body. The compensation layer has at least two support sections in the peripheral direction of the honeycomb body which exert greater forces in the radial direction upon the honeycomb body than outside the support sections in remaining peripheral regions. The support sections are disposed in regions where the honeycomb body has greater radial strength. Steps can be taken to produce the support sections on the compensation layer, by using support segments on the housing and/or beads on the honeycomb body, in each case in the peripheral regions of greater strength. The invention is particularly suitable for simple and sound installation of thin-walled extruded ceramic honeycomb bodies in metal housings.

Dependent claims

A honeycomb body configuration, comprising:

a honeycomb body disposed in said metal housing, said honeycomb body having a radial direction, a periphery defining a peripheral direction, varying radial strength along said periphery defining regions of greater radial strength, and dividing walls defining and separating a multiplicity of channels from one another;
and
a compensation layer disposed at least in partial regions of said periphery between said housing and said honeycomb body, said compensation layer having at least two support sections in said peripheral direction of said honeycomb body and having remaining peripheral regions outside said at least two support sections, said at least two support sections disposed in said regions of greater radial strength, said at least two support sections exerting greater forces in radial direction upon said honeycomb body than in said remaining peripheral regions, and said at least two support sections constituted at least partly by at least one insert formed of a metal material.
