Heat shield grommet

A heat shield, comprising:

• a first shell, wherein an edge of the first shell defines, at least, a portion of a shield opening;
• and
• a grommet located in the shield opening, wherein the edge of the first shell is located in a shield groove defined, at least partially, by an outer flange and an inner flange of the grommet, wherein the first shell is located radially between the outer flange and the inner flange such that the outer flange overlaps the first shell in a radially outward direction and the inner flange overlaps the first shell in a radially inward direction, wherein the grommet further comprises:
• a radially outward surface;
• a first radially inward surface opposite the radially outward surface;
• a plug opening formed through the radially outward surface and the first radially inward surface;
• an exterior radial surface extending radially from the radially outward surface to the first radially inward surface, wherein the shield groove is formed in the exterior radial surface;
• a first inward protrusion extending radially inward from the first radially inward surface and away from the radially outward surface, the first inward protrusion including a second radially inward surface oriented away from the radially outward surface, wherein a first distance between the radially outward surface and the first radially inward surface is less than a second distance between the radially outward surface and the second radially inward surface of the first inward protrusion;
• a first recessed surface located radially inward of the radially outward surface and oriented in the radially outward direction;
• a first interior radial surface extending radially from the first recessed surface to the first radially inward surface, wherein the first radially inward surface extends from the exterior radial surface to the first interior radial surface;
• a second recessed surface located radially inward of the radially outward surface and oriented in the radially outward direction;
• and
• a second interior radial surface oriented toward the first interior radial surface and extending radially from the second recessed surface to the first radially inward surface, wherein the first radially inward surface extends from the exterior radial surface to the second interior radial surface.

A wheel assembly, comprising:

• a wheel;
• a torque bar coupled to the wheel, the torque bar include a first sidewall and a second sidewall;
• and
• a heat shield located radially between the torque bar and the wheel, the heat shield comprising a grommet, wherein the grommet is located in a shield opening defined by an edge of the heat shield, and wherein the grommet includes:
• a radially outward surface oriented away from the torque bar;
• a radially inward surface opposite the radially outward surface;
• an exterior radial surface extending from the radially outward surface to the radially inward surface of the grommet, the exterior radial surface defining a shield groove, the edge of the heat shield being located in the shield groove;
• and
• a first inward protrusion extending radially inward from the radially inward surface of the grommet, wherein the first inward protrusion is located in a groove defined, at least partially, by the first sidewall and the second sidewall of the torque bar.
