Disc brake and wheel assembly

Claim 1

A disc brake and wheel assembly comprising: an annular brake disc having opposed annular friction surfaces and a peripheral surface, axially extending circumferentially spaced lands and grooves formed on said peripheral surface in alternating arrangement; means selectively frictionally engaging said disc friction surfaces; and a wheel assembly having a hub and a rim and a brake disc support and drive member, said member having a generally radially extending first section mounted on said hub and a generally cylindrical second section integrally formed with said first section, said member second section having circumferentially spaced projections received in said disc grooves and engaging the edges of said disc lands in rotary driving and axially relatively movable relation whereby said disc is rotatably driven with said wheel assembly and axially movable in relation thereto for brake adjustment, said wheel assembly further having a wheel disc section axially adjacent said brake disc support and drive member and secured to said hub and said rim, said brake disc support and drive member being radially inward of and spaced from said rim, said brake disc support and drive member projections being axially extending fingers, each of said brake disc grooves receiving a set of three of said axially extending fingers, each set of three fingers having the edges of the intermediate finger engaging the adjacent edges of the two outer fingers in friction damping relation, the intermediate finger being offset radially relative to the two outer fingers, the other edges of the two outer fingers engaging the adjacent edges of said brake disc lands in friction damping relation, at least one of the three fingers of each set forcibly engaging the bottom of the brake disc groove, said friction damping relations existing in the brake released and actuated conditions.
