Bearing mat for catalyst carrier arrangement in motor vehicle, has recess, where sheeting density within thickness reduction range does not exceed upper sheeting density limit value and does not fall below lower sheeting density limit value

摘要

#CMT# #/CMT# The mat (18) has a recess with a material thickness reduced in relation to a reference material thickness. A sheeting density within a range of the thickness reduction in an assembled condition of the bearing mat corresponds to a given sheeting density value related to a given ceramic body region and/or housing range. The sheeting density within the range of the thickness reduction in the assembled condition does not exceed an upper sheeting density limit value and does not fall below a lower sheeting density limit value. #CMT#USE : #/CMT# Bearing mat for a ceramic body of an exhaust-gas cleaning system for a catalyst carrier arrangement in a motor vehicle. #CMT#ADVANTAGE : #/CMT# The sheeting density within the range of the thickness reduction in the assembled condition of the bearing mat does not exceed the given upper sheeting density limit value and does not fall below the lower sheeting density limit value, thus achieving a reliable and fatigue endurable holding of the catalyst carrier element in the metal housing, and enabling a specific and individual pressure distribution under consideration of complicated configurations of the catalyst carrier arrangement with favorable manufacturing expenditure of the mat. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a catalyst carrier arrangement for an exhaust gas cleaning device in a motor vehicle, with a bearing mat provided between a ceramic carrier and a metal housing. 10 : Catalyst carrier arrangement 14 : Flow-through channels 16 : Outer metal housing 16a : Inlet funnel 18 : Bearing mat.
