A wheel assembly includes an inboard wheel portion having a rim and a disk. A radially inward surface of the rim and an inboard surface of the disk define a wheel well cavity configured to house a brake assembly. The wheel assembly also includes a torque bar (e.g., a torque bar of the brake assembly) mounted to the inboard wheel portion. Further, the wheel assembly includes a retainer coupled to the torque bar and disposed radially between the torque bar and the radially inward surface of the rim of the inboard wheel portion. The retainer includes a first end, a second end opposite the first end, and a body extending between the first end and the second end. The body includes opposing longitudinal sides configured to respectively engage and retain a respective heat shield segment of a segmented annular heat shield.
