Abstract

A muffler brace assembly for a vehicle includes a muffler and a pipe connected to an inlet of the muffler. A brace member has a first end and a second end. The first end of is connected to the pipe and the second end is connected to the muffler. A lowermost portion of the brace member is disposed lower than lowermost portions of the pipe and the muffler.

First claim

What is claimed is:

1. A muffler brace assembly for a vehicle comprising:
a muffler;
a pipe connected to an inlet of the muffler; and
a brace member having a first end and a second end, the first end being connected to the pipe and the second end being directly connected to the muffler, a lowermost portion of the brace member being disposed lower than lowermost portions of the pipe and the muffler,
the second end of the brace member being spaced from the inlet of the muffler in a widthwise direction of the vehicle to substantially prevent transferring a force imparted to the brace member to the inlet of the muffler.

2. The muffler brace assembly according to claim 1 , wherein
the pipe extends from a coupling joint upstream of the muffler to the muffler inlet.

3. The muffler brace assembly according to claim 1 , wherein
the brace member includes a first welded portion welded to the pipe.

4. The muffler brace assembly according to claim 3 , wherein
the brace member includes a second welded portion welded to the muffler.

5. The muffler brace assembly according to claim 3 , wherein
the first welded portion is welded to an uppermost surface of the pipe.

6. The muffler brace assembly according to claim 3 , wherein
the first welded portion extends at least sixty degrees on a circumference of the pipe.

7. The muffler brace assembly according to claim 3 , wherein
a connecting portion of the brace member between the pipe and the muffler extends at an angle relative to the ground when viewed in a widthwise direction of a vehicle.

8. The muffler brace assembly according to claim 1 , wherein
a lowermost portion of the pipe is spaced from the brace member.

9. The muffler brace assembly according to claim 1 , wherein
the lowermost portion of the brace member is disposed closer to the pipe than to the muffler when viewed in a widthwise direction of the vehicle.

10. The muffler brace assembly according to claim 1 , wherein
a connecting portion of the brace member between the pipe and the muffler is substantially linear when viewed in a widthwise direction of a vehicle.

11. The muffler brace assembly according to claim 1 , wherein
the brace member has a curved portion disposed between the pipe and the muffler when viewed in a widthwise direction of a vehicle.

12. The muffler brace assembly according to claim 11 , wherein
the curved portion is curved toward the ground.

13. The muffler brace assembly according to claim 11 , wherein
the curved portion is disposed closer to the pipe than to the muffler when viewed in a widthwise direction of the vehicle.

14. The muffler brace assembly according to claim 11 , wherein
the curved portion is the lowermost portion of the brace member.

15. The muffler brace assembly according to claim 1 , wherein
the first welded portion is disposed in a first plane, and the second welded portion is disposed in a second plane, the second plane being different from the first plane.

16. The muffler brace assembly according to claim 3 , wherein
the pipe is disposed between the first welded portion and the muffler when viewed in a widthwise direction of a vehicle.

17. The muffler brace assembly according to claim 1 , wherein
the brace member is made of stainless steel.

18. A muffler brace assembly for a vehicle comprising:
a first muffler;
a second muffler;
a first pipe extending from a first inlet of the first muffler to a first coupling joint;
a second pipe extending from a second inlet of the second muffler to a second coupling joint;
a first brace member having a first end and a second end, the first end being connected to the first pipe and the second end being connected to the first muffler, a lowermost portion of the first brace member being disposed lower than lowermost portions of the first pipe and the first muffler; and
a second brace member having a third end and a fourth end, the third end being connected to the second pipe and the fourth end being connected to the second muffler, a lowermost portion of the second brace member being disposed lower than lowermost portions of the second pipe and the second muffler,
the first and second coupling joints being disposed between the first and second brace members when viewed in a longitudinal direction of a vehicle.

19. The muffler brace assembly according to claim 18 , wherein
the first brace member includes a first welded portion welded to the first pipe, the first welded portion extending at least sixty degrees on a circumference of the first pipe; and
the second brace member includes a second welded portion welded to the second pipe, the second welded portion extending at least sixty degrees on a circumference of the second pipe.

20. The muffler brace assembly according to claim 18 , wherein
a lowermost portion of the first pipe is spaced from the first brace member; and
a lowermost portion of the second pipe is spaced from the second brace member.
