Abstract
An exhaust component assembly includes a heat shield and a mounting structure to attach the heat shield to an outer housing of an exhaust component. The mounting structure comprises a primary insulator located between an outer surface of the outer housing and an inner surface of the heat shield and at least one secondary insulator positioned adjacent to the primary insulator. A method of assembling the heat shield to the outer housing of the exhaust component assembly is also disclosed.
Claims25
An exhaust component assembly comprising:
- a heat shield;
- and
- a mounting structure to attach the heat shield to an outer housing of an exhaust component, wherein the mounting structure comprises a primary insulator located between an outer surface of the outer housing and an inner surface of the heat shield and at least one secondary insulator positioned adjacent the primary insulator and located between the outer surface of the outer housing and the inner surface of the heat shield.
An exhaust component assembly comprising:
- a heat shield;
- and
- a mounting structure to attach the heat shield to an outer housing of an exhaust component, wherein the mounting structure comprises a primary insulator located between an outer surface of the outer housing and an inner surface of the heat shield and at least one secondary insulator positioned adjacent the primary insulator and the primary insulator comprises an insulating mat wrapped around the outer housing, and wherein the insulating mat has a first edge and a second edge opposite of the first edge, and wherein the at least one secondary insulator comprises at least a first piece of material positioned at the first edge and a second piece of material positioned at the second edge, and wherein the heat shield is placed over outer surfaces of the first and second pieces of material and the insulating mat and is held in compression against the outer housing by at least one attachment structure.
An exhaust component assembly comprising:
- a heat shield;
- and
- a mounting structure to attach the heat shield to an outer housing of an exhaust component, wherein the mounting structure comprises a primary insulator located between an outer surface of the outer housing and an inner surface of the heat shield and at least one secondary insulator positioned adjacent the primary insulator, and wherein the primary insulator comprises an air gap and wherein the at least one secondary insulator comprises at least a first ring or band positioned at one edge of the air gap and a second ring or band positioned at an opposite edge of the air gap.
A method of assembling a heat shield to an outer housing of an exhaust component assembly comprising the steps of:
- positioning a primary insulator between an outer surface of the outer housing and an inner surface of the heat shield;
- positioning at least one secondary insulator adjacent to the primary insulator;
- and
- placing the heat shield over the primary and secondary insulators such that the heat shield is held fixed relative to the outer housing, and compressing the heat shield against the outer housing.
A method of assembling a heat shield to an outer housing of an exhaust component assembly comprising the steps of:
- positioning a primary insulator between an outer surface of the outer housing and an inner surface of the heat shield;
- positioning at least one secondary insulator adjacent to the primary insulator;
- and
- placing the heat shield over the primary and secondary insulators such that the heat shield is held fixed relative to the outer housing, and wherein the primary insulator and the at least one secondary insulator provide structural support to attach the heat shield to the outer housing without any other attachment structures.
An exhaust component assembly comprising:
- a heat shield;
- and
- a mounting structure to attach the heat shield to an outer housing of an exhaust component, wherein the mounting structure comprises a primary insulator located between an outer surface of the outer housing and an inner surface of the heat shield and at least one secondary insulator positioned adjacent the primary insulator, and wherein the primary insulator and the at least one secondary insulator provide structural support to attach the heat shield to the outer housing without any other attachment structures.
