Abstract
A muffler assembly includes an outer shell defining an internal cavity that extends between first and second ends. A first end cap is attached to the first end and a second end cap is attached to the second end. The first and second end caps provide a substantially enclosed internal cavity within the outer shell. A heat shield extends along a length of the outer shell and has a first shield end attached to the first end cap and a second shield end attached to the second end cap. The first and second shield ends are deformed around an outer perimeter of the first and second ends caps, or separate retaining members are used to secure the first and second shield ends to the first and second end caps.
Claims21
A muffler assembly comprising:
- an outer shell extending between first and second ends;
- a first end cap attached to said first end;
- a second end cap attached to said second end;
- and
- a heat shield extending along a length of said outer shell wherein a first shield end is mounted over said first end cap at a first attachment interface and a second shield end is mounted over said second end cap at a second attachment interface.
A method for assembling at heat shield to a muffler comprising:
- providing an outer shell having a first end cap attached to a first shell end and a second end cap attached to a second shell end;
- securing a first heat shield end directly over the first end cap at a first attachment interface;
- and
- securing a second heat shield end directly over the second end cap at a second attachment interface.
