Drive key heat shield and support for wheel rim heat shield of multiple disc brake

A wheel and heat shield assembly comprising:

• a tire supporting wheel rim defining a brake cavity adapted to receive a brake assembly, said brake assembly having rotatable and non-rotatable frictionally engageable members;
• circumferentially spaced elongated drive key means carried by said wheel rim said drive key means extending radially inwardly from said wheel rim into engagement with said rotatable members;
• a plurality of rim heat shield members each being independently and removably secured in position between said drive key means to define a substantially continuous annular wall having radially spaced-apart relationship to said wheel rim;
• and
• each of said drive key means including a boss member carried by said wheel rim, a cap key member removably secured to said boss member so that said cap key member engages said rotatable members, and a key boss cap heat shield member disposed between said cap key member and said boss member, with said key boss cap heat shield member extending over said boss and interconnecting adjacent said rim heat shield members, said interconnection adapted to maintain said independent removability of said rim heat shield members from said assembly.
