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 of an internal combustion engine of a vehicle, the support ring comprising a support element body comprising:
a plurality of body segments; and a support arrangement connecting the body segments to one another.

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:
at least one of all body segments has a U-profile design with a U-profile; and the support arrangement is at least partially accommodated in a U-profile interior space of the U-profile.

5 . An exhaust gas duct system support ring in accordance with claim 4 , 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.

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

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

8 . An exhaust gas duct system support ring in accordance with claim 7 , wherein the support arrangement is comprised of a wire mesh.

9 . 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 frictional connection or a material connection or by both a frictional connection and a material connection.

10 . 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; and a support arrangement connecting the body segments to one another.

11 . An exhaust gas duct assembly unit in accordance with claim 10 , wherein the exhaust gas treatment device comprises a catalytic converter device.

12 . An exhaust gas duct assembly unit in accordance with claim 11 , 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.

13 . An exhaust gas duct assembly unit in accordance with claim 12 , wherein a gap is formed between the body segment end areas.

14 . An exhaust gas duct assembly unit in accordance with claim 11 , wherein:
at least one of all body segments has a U-profile design with a U-profile; and the support arrangement is at least partially accommodated in a U-profile interior space of the U-profile.

15 . An exhaust gas duct assembly unit in accordance with claim 14 , 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.

16 . An exhaust gas duct assembly unit in accordance with claim 15 , wherein the support arrangement extends in a direction away from the connection area at least beyond the shorter U leg.

17 . An exhaust gas duct assembly unit in accordance with claim 11 , wherein the support arrangement is flexible, or 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 being flexible, the support arrangement having a ring configuration and at least one body segment comprising a sheet metal part.

18 . An exhaust gas duct assembly unit in accordance with claim 17 , wherein the support arrangement is comprised of a wire mesh.

19 . An exhaust gas duct assembly unit in accordance with claim 11 , wherein at least one body segment of the plurality of body segments is rigidly connected to the support arrangement by a frictional connection or a material connection or by both a frictional connection and a material connection.
