Exhaust treatment component mounting system
View Patent ↗An exhaust treatment component mounting system including an exhaust treatment component canister that includes a cleat ring, and an exhaust treatment component housing including a radially outwardly extending flange. A torsion rod including a first end that mates with the flange of the housing, and a second end including a coupling that mates with the cleat ring, wherein during connection between the first end and the second end of the torsion rod, the canister is rigidly secured to the housing.
1. An exhaust treatment component mounting system, comprising:
an exhaust treatment component canister containing a first substrate brick, the canister including a cleat ring;
an exhaust treatment component housing containing a second substrate brick, the housing including a radially outwardly extending flange; and
a tension rod assembly including a first rod and a second rod, the first rod having a first end that mates with the flange of the housing, the second rod having a first end including a retainer that mates with the cleat ring, and second ends of the first and second rods being threadingly interconnected,
wherein during interconnection between first and second rods, the canister is rigidly secured to the housing.
2. The exhaust treatment component mounting system of claim 1 , wherein the second end of the second rod is a male component, and the second end of the first rod is a female component that mates with the male component.
3. The exhaust treatment component mounting system of claim 1 , wherein the first end of the first rod includes a bulb portion.
4. The exhaust treatment component mounting system of claim 1 , wherein each of the first substrate brick and the second substrate bricks are selected from the group consisting of a particulate filter and a catalyzed substrate.
5. The exhaust treatment component mounting system of claim 4 , wherein the catalyzed substrate is a selective catalytic reduction (SCR) substrate or a diesel oxidant catalyst (DOC) substrate.
6. The exhaust treatment component mounting system of claim 1 , further comprising a gasket positioned between the canister and the housing.
7. The exhaust treatment component mounting system of claim 6 , wherein the housing includes a first gasket flange and the canister includes a second gasket flange, with the gasket positioned therebetween.
8. The exhaust treatment component mounting system of claim 7 , wherein the first and second gasket flanges extend radially outwardly relative to the housing and canister, respectively.
9. The exhaust treatment component mounting system of claim 1 , wherein each of the cleat ring and the retainer have a radius of curvature direction that correspond to each other.
10. An exhaust treatment component mounting system, comprising:
an exhaust treatment component canister, the canister including a cleat ring about a circumference thereof;
an exhaust treatment component housing including a radially outwardly extending flange about at least a portion thereof; and
a coupling including a retainer, a first rod, and a second rod, a first end of the first rod being coupled to the flange of the housing and a first end of the second rod being coupled to the retainer, and second ends of the first and second rods being threadingly interconnected
wherein relative rotation between the first rod and the second rod engages the retainer with the cleat ring to rigidly secure the canister to the housing.
11. The exhaust treatment component mounting system of claim 10 , wherein the second end of the second rod is a male component, and the second end of the first rod is a female component that mates with the male component.
12. The exhaust treatment component mounting system of claim 10 ,wherein the first end of the first rod includes a bulb portion.
13. The exhaust treatment component mounting system of claim 12 , wherein the bulb includes an anti-rotation feature.
14. The exhaust treatment component mounting system of claim 10 ,wherein each of the exhaust treatment component canister and housing include a substrate brick that is either a particulate filter or a catalyzed substrate.
15. The exhaust treatment component mounting system of claim 14 , wherein the catalyzed substrate is a selective catalytic reduction (SCR) substrate or a diesel oxidation catalyst (DOC) substrate.
16. The exhaust treatment component mounting system of claim 10 , further comprising a gasket positioned between the canister and the housing, and compressed by the coupling.
17. The exhaust treatment component mounting system of claim 16 ,wherein the housing includes a first gasket flange and the canister includes a second gasket flange, with the gasket secured therebetween.
18. The exhaust treatment component mounting system of claim 17 , wherein the first and second gasket flanges extend radially outwardly relative to the housing and canister, respectively.
19. The exhaust treatment component mounting system of claim 18 ,wherein the first gasket flange includes a circumferentially extending lip that overlaps the second gasket flange with the gasket therebetween.
20. The exhaust treatment component mounting system of claim 10 , wherein the retainer includes a curved surface and the cleat ring includes a curved seat, the curved surface being loaded in biased engagement with the curved seat.
21. The exhaust treatment component mounting system of claim 10 , wherein the retainer includes a base portion including an aperture and an angled finger portion, the second rod extending through the aperture and the finger portion being selectively engageable with the cleat.
