摘要： A molded braking and support wheel assembly for a multi-wheeled wheelchair for a handicapped person. The wheel assembly includes a braking support wheel molded as a single unit of plastic or plastic-like material having concentric components including a tire receiving rim, a wheel bearing and brake assembly receiving hub, and spaced wheel spokes substantially radially extending between the hub and rim. A ring or band-shaped metal brake drum is also molded as a unit into the hub, the brake drum having a generally cylindrical inner braking friction surface and plastic-interlocking outer surface features which permanently interlock with the plastic material when the braking support wheel is mold formed. The plastic-interlocking outer features are molded with the hub into a single unit with the support wheel to secure the brake drum from relative movement in the hub. The brake drum defines a generally cylindrical cavity for operatively receiving the brake assembly. The hub includes a wheel bearing cavity coaxial with said brake drum for receiving spaced wheel bearings positioned therein.
