HONEYCOMB BODY FOR EXHAUST-GAS AFTERTREATMENT, METHOD FOR PRODUCING A HONEYCOMB BODY AND MOTOR VEHICLE HAVING A HONEYCOMB BODY

摘要

A honeycomb body for exhaust gas aftertreatment includes a first end face, a second end face, a central axis that penetrates the two end faces and a length. The honeycomb body has at least one at least partially structured metallic layer which is disposed about the central axis. A structure of the at least one metallic layer has elevations and depressions which extend at least over part of the length of the honeycomb body and run obliquely to the central axis. At least one metallic connecting strip is provided between adjacent regions of the at least one metallic layer. The metallic connecting strip is shorter than the length of the honeycomb body and forms a brazed connection or welded connection to the adjacent regions. A method for producing such a honeycomb body and a motor vehicle having the honeycomb body are also provided.

主权项

1. A honeycomb body for exhaust-gas aftertreatment, the honeycomb body comprising:
a length, a first end side, a second end side and a central axis extending through said first and second end sides; at least one at least partially structured metallic layer disposed around said central axis, said at least one at least partially structured metallic layer having a structure with elevations and depressions extending at least over a part of said length and running obliquely relative to said central axis, and said at least one at least partially structured metallic layer having adjacent regions; at least one metallic connecting strip disposed between said adjacent regions and being shorter than said length; and a brazed connection or welded connection formed between said at least one metallic connecting strip and said adjacent regions.
