ABSTRACT:
The aircraft brake torque transfer assembly of a brake (30) comprises an aircraft axle (10) having at one axial location an axle flange (18) flange which includes about the circumference thereof a plurality of teeth members or splines (19). An aircraft wheel (20) is mounted upon a set of roller bearing assemblies (15, 17) with one roller bearing assembly engaging a nut assembly (14). The other 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 bolts (60) with nuts (64) to attach a retention ring (50) to the torque tube (24). The retention ring (50) includes a central, generally annular opening (51) with a plurality or teeth or splines (54) disposed thereabout. The teeth or splines (54) mesh with the teeth or splines (19) around the circumference of the axle flange (18) to secure abuttingly and nonrotatably the retention ring (50) to the axle flange (18), and thereby secure nonrotatably the torque tube (24) relative to the axle (10). The retention ring (50) includes several engagement members (55, 55A) which enable quick assembly and disassembly with the axle flange (18).
