Exhaust component, method for producing such an exhaust component, and device for carrying out said method

Abstract

An exhaust-gas component, having a—cross-sectionally—rectangular arrangement composed of at least one—cross-sectionally—rectangular exhaust-gas aftertreatment element; and a housing which engages around the—cross-sectionally—rectangular arrangement. The housing has a rectangular cross section and is divided, along a diagonal of the cross section, into two housing parts. The housing is arranged under compressive stress in an external housing.

         16 . An exhaust-gas component, having
 a cross-sectionally rectangular arrangement composed of at least one cross-sectionally rectangular exhaust-gas aftertreatment element;   a housing that engages around the cross-sectionally rectangular arrangement, wherein the housing has a rectangular cross section and is divided, along a diagonal of the cross section, into two housing parts; and   an external housing, the housing being arranged under compressive stress in the external housing.   
     
     
         17 . The exhaust-gas component according to  claim 16 , wherein the two housing parts are forced toward one another under stress at mutually adjacent housing edges. 
     
     
         18 . The exhaust-gas component according to  claim 16 , wherein the two housing parts are formed, in cross-section, as L-shaped sheet-metal elements. 
     
     
         19 . The exhaust-gas component according to  claim 18 , wherein an edge length, measured in a cross-sectional plane, of a housing edge of at least one of the two housing parts is smaller than a length of an arrangement edge, bearing against the housing edge in an assembled state, of the arrangement of the at least one exhaust-gas aftertreatment element in a stress-relieved state. 
     
     
         20 . The exhaust-gas component according to  claim 16 , wherein the two housing parts have, at housing edges which are mutually adjacent in an assembled state, positive-locking elements configured to engage one another in the assembled state. 
     
     
         21 . The exhaust-gas component according to  claim 16 , further comprising at least one compression mat arranged between the at least one exhaust-gas aftertreatment element and the housing and/or between at least two exhaust-gas aftertreatment elements. 
     
     
         22 . The exhaust-gas component according to  claim 16 , further comprising a plurality of identical compression mats, wherein each compression mat has at least one slot. 
     
     
         23 . The exhaust-gas component according to  claim 22 , wherein at least two of the compression mats are arranged so as to be fitted into one another. 
     
     
         24 . The exhaust-gas component according to  claim 16 , wherein the two housing parts have face-side, inwardly directed housing flanges. 
     
     
         25 . The exhaust-gas component according to  claim 16 , wherein the external housing has external-housing flanges directed outward at a face side and which have flange positive-locking elements. 
     
     
         26 . A method for producing an exhaust-gas component, comprising the steps of:
 providing a cross-sectionally L-shaped first housing part;   arranging at least one cross-sectionally rectangular exhaust-gas aftertreatment element on the first housing part to form a cross-sectionally rectangular arrangement;   placing a cross-sectionally L-shaped second housing part on to the arrangement to produce a compression unit;   applying a compression force to the housing parts so that the compression unit is compressed; and   pressing the compression unit under compressive stress into an external housing.   
     
     
         27 . The method according to  claim 26 , including arranging at least one compression mat between at least two exhaust-gas aftertreatment elements and/or between at least one exhaust-gas aftertreatment element and the housing formed by the first and the second housing parts. 
     
     
         28 . The method according to  claim 26 , including arranging the first housing part on a cross-sectionally L-shaped support surface of a holding device. 
     
     
         29 . The method according to  claim 26 , wherein the compression force is applied to the housing parts by clamping brackets clamped around the compression unit. 
     
     
         30 . The method according to  claim 26 , wherein the pressing of the compression unit into the external housing is performed by applying a pressing force to face-side, inwardly directed housing flanges of the housing parts. 
     
     
         31 . A device for carrying out a method according to  claim 26 , comprising:
 a holding device that has a cross-sectionally L-shaped support surface; and   at least one clamping bracket for applying a compression force to a compression unit of an exhaust-gas component to be produced.   
     
     
         32 . The device according to  claim 31 , wherein the at least one clamping bracket has a first clamping bracket part arrangeable on the support surface. 
     
     
         33 . The device according to  claim 31 , wherein the support surface has at least one recess for arrangement of the first clamping bracket part.
