Exhaust mounting system
View Patent ↗An exhaust mounting system includes an exhaust component having a pair of ridges along an outer perimeter. A mounting band is disposed around the outer perimeter of the exhaust component between the ridges. An isolation pad is disposed between the exhaust component and the mounting bracket for absorbing vibration energy between the mounting band and the exhaust component.
1. An exhaust mounting system comprising:
an exhaust component having a pair of ridges along an outer perimeter, wherein the exhaust component is one of a particulate filter and an oxidization catalyst;
a mounting band disposed around the outer perimeter of the exhaust component between the ridges; and
an isolation pad disposed between the exhaust component and the mounting band for absorbing vibration energy between the mounting band and the exhaust component.
2. The exhaust mounting system of claim 1 wherein the mounting band grips the exhaust component.
3. The exhaust mounting system of claim 2 wherein the ridges are parallel to one another.
4. The exhaust mounting system of claim 3 wherein the ridges are spaced apart to define a gap, and the gap has a width greater than a width of the mounting band in order to allow for thermal expansion and contraction of the exhaust component.
5. The exhaust mounting system of claim 4 wherein the exhaust component can move relative to the mounting band.
6. The exhaust mounting system of claim 5 wherein the movement of the exhaust component relative to the mounting band is limited by the ridges contacting the mounting band.
7. The exhaust mounting system of claim 1 wherein the ridges are brackets coupled to a surface of the exhaust component.
8. The exhaust mounting system of claim 1 wherein the ridges are welded onto an outer surface of the exhaust component.
9. The exhaust mounting system of claim 1 wherein the ridges are hydroformed in an outer surface of the exhaust component.
10. The exhaust mounting system of claim 1 wherein the ridges are located centrally on a cylindrical portion of the exhaust mounting system.
11. The exhaust mounting system of claim 1 further comprising a plurality of mounting bands, each mounting band disposed between a pair of ridges located on the exhaust component.
12. The exhaust mounting system of claim 1 wherein the mounting band includes a mounting bracket for connecting the mount band to a component of a powertrain.
13. The exhaust mounting system of claim 1 wherein the isolation pad is a wire mesh.
14. The exhaust mounting system of claim 13 wherein the isolation pad runs along the entire perimeter of the exhaust component.
15. The exhaust mounting system of claim 13 wherein the isolation pad is a discrete element that runs along a portion of the perimeter of the exhaust component.
16. The exhaust mounting system of claim 13 wherein the isolation pad extends around at least one side of the mounting band.
17. The exhaust mounting system of claim 1 wherein the exhaust component is a Diesel particulate filter.
18. The exhaust mounting system of claim 1 wherein the exhaust component is a Diesel oxidation catalyst.
19. An exhaust mounting system comprising:
an exhaust component having a cylindrical portion that defines an axis, the cylindrical portion having an outer surface and a pair of spaced apart parallel ridges that are integrally formed in the outer surface, wherein the pair of spaced apart parallel ridges extend a distance above the outer surface and circumscribe the cylindrical portion, wherein the spaced apart parallel ridges are centrally located along the axis on the cylindrical portion, and wherein the exhaust component is one of a particulate filter and an oxidization catalyst;
an isolation pad disposed between the pair of spaced apart parallel ridges and in contact with the outer surface of the exhaust component; and
a mounting band disposed between the ridges and overtop the isolation pad,
wherein the isolation pad is configured to absorb vibration energy between the mounting band and the exhaust component, and
wherein the pair of spaced apart parallel ridges are spaced to allow the exhaust component to move relative to the mounting band in a direction parallel to the axis and wherein the distance that the pair of spaced apart parallel ridges extend above the outer surface is greater than a distance between the mounting band and the outer surface.
