Centerline two piece wheel and brake assembly

A dirigible wheel assembly for a surface vehicle, comprising:

• a wheel member;
• a hub;
• a wheel spindle journalled in said hub;
• means supporting said hub for turning movement about a steering axis lying in a plane normal to the axis of rotation of said spindle and comprising a yoke member having parallel arms extending above and below said hub, and bearing means between said arms and said hub and forming a pivot for swinging said hub about said steering axis;
• said wheel member comprising a tire rim and a spider attached to said spindle by an attaching member, and an inwardly directed annular flange on the inner periphery of said wheel member;
• an annular brake rotor disc presenting annular brake shoe engaging surfaces lying in planes normal to the axis of rotation of said spindle;
• attaching means on said brake rotor disc for rigidly attaching the brake rotor disc to the inwardly directed annular flange, and a brake caliper and bracket assembly having a brake caliper housing secured thereto, and at least one brake surface pad for selectively applying pressure against said brake shoe engaging surfaces, said hub having vertical surfaces on each side substantially parallel to the axis of rotation of said wheel spindle, said brake caliper and bracket assembly having supports for said brake caliper housing on opposing sides of said brake caliper housing extending over said yoke and parallel to said axis of rotation of said wheel spindle and mating with said hub surfaces, and securing means for securing said supports to said hub at the mating surfaces.
