Abstract

A support ring ( 36 ) for an exhaust gas duct system, especially of an internal combustion engine of a vehicle, comprises a support element body ( 40 ) with a plurality of body segments ( 46, 48 ) and with a support arrangement ( 42 ) connecting the body segments ( 46, 48 ) to one another.

First claim

What is claimed is:

1. An exhaust gas duct system support ring for an exhaust gas duct system of an internal combustion engine of a vehicle, the support ring comprising:
a support element body comprising a plurality of body segments, wherein all body segments have a U-profile design with a U-profile;
a flexible support arrangement comprised of a wire mesh connecting the body segments to one another, wherein the support arrangement is at least partially accommodated in a U-profile interior space of the U-profile, wherein at least one body segment of the plurality of body segments is rigidly connected to the support arrangement by a frictional connection by local pressing of the mesh wire of the support arrangement.

2. An exhaust gas duct system support ring in accordance with claim 1 , wherein:
at least two body segments of the plurality of body segments are adjacent to one another in opposing body segment end areas; and
the support arrangement connects the body segments to one another with the opposing body segment end areas adjacent to one another.

3. An exhaust gas duct system support ring in accordance with claim 2 , wherein a gap is formed between the body segment end areas.

4. An exhaust gas duct system support ring in accordance with claim 1 , wherein:
the U profile has a radially inner U leg, a radially outer U leg and a connection area portion connecting the U legs; and
the radially inner U leg is shorter than the radially outer U leg.

5. An exhaust gas duct system support ring in accordance with claim 4 , wherein the support arrangement extends in a direction away from the connection area at least beyond the shorter U leg.

6. An exhaust gas duct system support ring in accordance with claim 1 , wherein the support arrangement has a ring configuration or at least one body segment comprises a sheet metal part or any combination of the support arrangement is flexible, the support arrangement having a ring configuration and at least one body segment comprising a sheet metal part.

7. An exhaust gas duct system support ring in accordance with claim 1 , wherein at least one body segment of the plurality of body segments is rigidly connected to the support arrangement by a material connection or by both the frictional connection and the material connection.

8. An exhaust gas duct assembly unit for an exhaust gas duct system for an internal combustion engine of a vehicle, the exhaust gas duct assembly unit comprising:
a tubular exhaust gas duct element;
an exhaust gas treatment device arranged in the exhaust gas duct element; and
a support ring at at least one end area of the exhaust gas treatment device, the support ring comprising a support element body comprising a plurality of body segments, wherein all body segments have a U-profile design with a U-profile; and
a flexible support arrangement connecting the body segments to one another, said flexible support arrangement comprising a wire mesh, wherein the flexible support arrangement is at least partially accommodated in a U-profile interior space of the U-profile, wherein at least one body segment of the plurality of body segments is rigidly connected to the flexible support arrangement by a frictional connection by local pressing of the mesh wire of the flexible support arrangement.

9. An exhaust gas duct assembly unit in accordance with claim 8 , wherein the exhaust gas treatment device comprises a catalytic converter device.

10. An exhaust gas duct assembly unit in accordance with claim 9 , wherein:
at least two body segments of the plurality of body segments are adjacent to one another in opposing body segment end areas; and
the support arrangement connects the body segments to one another with the opposing body segment end areas adjacent to one another.

11. An exhaust gas duct assembly unit in accordance with claim 10 , wherein a gap is formed between the body segment end areas.

12. An exhaust gas duct assembly unit in accordance with claim 8 , wherein:
the U profile has a radially inner U leg, a radially outer U leg and a connection area portion connecting the U legs; and
the radially inner U leg is shorter than the radially outer U leg.

13. An exhaust gas duct assembly unit in accordance with claim 12 , wherein the support arrangement extends in a direction away from the connection area at least beyond the shorter U leg.

14. An exhaust gas duct assembly unit in accordance with claim 9 , wherein the support arrangement has a ring configuration or at least one body segment comprises a sheet metal part or any combination of the support arrangement is flexible, the support arrangement having a ring configuration and at least one body segment comprising a sheet metal part.

15. An exhaust gas duct assembly unit in accordance with claim 9 , wherein at least one body segment of the plurality of body segments is rigidly connected to the support arrangement a material connection or by both the frictional connection and the material connection.

16. An exhaust gas duct system support ring for an exhaust gas duct system of an internal combustion engine of a vehicle, the support ring comprising:
a support element body comprising a plurality of body segments, wherein all body segments have a U-shaped interior space;
a flexible support arrangement comprising a wire mesh, each of said plurality of body segments being connected to another one of said plurality of body segments via said wire mesh, said support arrangement being at least partially arranged in said U-shaped interior space of at least one of said plurality of body segments such that at least a portion of said wire mesh deforms to define a frictional connection for connecting said flexible support arrangement and said at least one of said plurality of body segments, wherein said at least one body segment of said plurality of body segments is rigidly connected to said support arrangement via said frictional connection.

17. An exhaust gas duct system support ring in accordance with claim 16 , wherein a gap is formed between end areas of said plurality of body segments, said wire mesh bridging said gap between said end areas of said plurality of body segments.

18. An exhaust gas duct system support ring in accordance with claim 17 , wherein said plurality of body segments comprises a first body segment, a second body segment and a third body segment, each of said first body segment, said second body segment and said third body segment being located at a spaced location from each other, wherein a first gap is defined between said first body segment and said second body segment, a second gap is defined between said second body segment and said third body segment and a third gap is defined between said first body segment and said third body segment, said wire mesh bridging said first gap, said second gap and said third gap.
