DETAILED DESCRIPTION OF THE INVENTION

Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1 thereof, there is seen a diagrammatic and partial cross section of a housing 1 having a housing thickness 6 in the region of 0.5 mm. An exhaust gas purification component 2 is illustrated in an interior space 3 of the housing 1. The housing 1 has a receptacle 4, close to an end side 5, which is formed in such a way as to run around at the outside. The receptacle 4 has been generated by bending a part of the housing 1. In this case, a bend radius 7 in the region of 5 mm has been created. A rearward-bent part of the housing 1, which is formed substantially parallel to that region of the housing 1 which forms the interior space 3, has a length 8 of 7 to 10 mm.

A first exhaust line section 10, which is disposed in the receptacle 4, is placed in contact with the outer part of the housing 1 that forms the receptacle 4. A materially integral connection 12 is provided in the contact region which is preferably formed so as to run around the housing 1. A corresponding material thickness 13 is provided for the joining which is provided through the use of welding.

A further embodiment variant for an exhaust system 9 of this type is shown in FIG. 2. In this case, it is again possible to see, in a partial cross section, the housing 1 which, in the interior, holds an exhaust gas purification component 2.

The exhaust gas purification component 2 is, for example, constructed in the manner of a honeycomb body from a plurality of metal foils or sheets 23 which form channels or passages 22 that can be traversed by the exhaust gas in a flow direction 16. The housing 1 or the exhaust gas purification component 2 has, after being aligned in the exhaust system 9, a defined inlet end side 17 and an outlet end side 18 relative to the flow direction 16. The housing 1 is disposed at a spacing 19 from the first exhaust line section 10 in the vicinity of the outlet end side 18. A fixing device 20 disposed in the spacing 19 holds the housing 1 at the spacing 19.

The receptacle 4 is again formed close to the inlet end side 17. In this embodiment variant, too, the first exhaust line section 10 is in engagement with the receptacle 4. In addition, further components of the exhaust line are positioned further out, outside the receptacle 4. Firstly, a third exhaust line section 21 (for example having a line thickness of approximately 0.5 mm) is placed in contact with the receptacle 4 at the outside. The third exhaust line section 21 can, for example, hold further exhaust gas purification components and/or permit a directed inflow of the exhaust gas into the exhaust gas purification component 2. In this embodiment variant, the outer closure is now formed by a second exhaust line section 11, so that the first exhaust line section 10 and the second exhaust line section 11 receive the third exhaust line section 21 and the receptacle 4 of the housing 1 in the manner of a sandwich. In the region of the materially integral connection 12, a material thickness is provided which is, for example, above 3 mm in this case and ensures a durable welded connection. This applies, in particular, with regard to the thin-walled or reduced-weight housing of the exhaust gas purification component used herein. The welded connection, which is referred to also as a so-called “tube canning”, is advantageous specifically in the case of thin-walled housings.

FIG. 3 is provided to illustrate the integration of an exhaust system 9 of this type in a motor vehicle 14. The figure illustrates a motor vehicle 14 having an internal combustion engine 15. The exhaust gas which is generated in the internal combustion engine 15 flows in a flow direction 16 through the exhaust system 9. The exhaust gas is supplied to various exhaust gas purification components (such as catalytic converters, filters, absorbers and the like). The figure also illustrates the position of a materially integral connection 12 with regard to a first exhaust line section 10 and a second exhaust line section 11. The housing 1 at the same time is fixed in the materially integral connection 12, as explained above.
