Abstract
The aircraft brake torque transfer assembly comprises an aircraft axle (10) having at one axial location an axle flange (18) which includes a plurality of radially extending slots (19, 119) about the circumference thereof, and at an opposite axial location a nut assembly (14) which engages the inner cone of a tapered roller bearing assembly (15) for an associated aircraft wheel (20). The aircraft wheel (20) engages another tapered roller bearing assembly (17) maintains in axial position a bushing assembly (21) and a foot (25) of a torque tube (24) which abuts against the axle flange (18). The aircraft brake (30) includes a piston housing (35) attached to the torque tube (24), and the torque tube (24) includes a plurality of openings (27) receiving key members (60) bolted to the torque tube (24). The key members (60) extend axially to be received in the respective slots (19) of the axle flange (18). The nut assembly (14) holds the wheel (20) and a bearing assembly mechanism (15, 17, 21) axially in place against the torque tube (24) which abuts the axle flange (18) so that the key member (60) transfers braking torque from the torque tube (24) to the axle flange (18) during brake operation. Alternatively, the key member (160) may comprise an integral key part (162) extending axially from the foot (25) of the torque tube (24) and received within a respective slot (119) in the axle flange (18) . The key members (60, 160) may be attached to or integral with the axle flange (18) and be received in complementary shaped openings in the torque tube (24).
