Abstract:
A wheel assembly includes a wheel including a spoke portion radially supporting a rim portion about a central axis, wherein the rim portion presents a radial outer surface relative to the central axis. A tire is mounted to the wheel and cooperates with the wheel to define a tire cavity between the radial outer surface of the rim portion and the tire. A foamed aluminum portion is supported by the wheel, and includes a plurality of pores arranged to define an open-cell foam. The plurality of pores of the foamed aluminum portion is disposed in fluid communication with the tire cavity to absorb noise from within the tire cavity. The foamed aluminum portion may be integrally cast with the wheel, or otherwise affixed to the wheel.
