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).
A brake torque transfer assembly of a brake, comprising axle means upon which is mounted rotatably a wheel via bearing means, the brake comprising a torque tube maintained at a predetermined axial position adjacent an axle flange of said axle means, a piston housing connected with said torque tube, at least one disc member connected with said torque tube, at least a second disc member connected with said wheel, and the torque tube located nonrotatably relative to the axle means via a retention ring connected with the torque tube and engaging nonrotatably the axle flange of said axle means, the retention ring having internal teeth means engaging teeth means at the circumference of said axle flange, the teeth means of the retention ring and the axle flange comprising a plurality of splines, the splines of the retention ring being located about a circumference of a central opening of the retention ring, detachable means for connecting the retention ring with said torque tube, the detachable connecting means comprising a bolt and nut with the bolt extending through aligned openings in the retention ring and torque tube, and the aligned openings in the torque tube located within a torque tube radial flange which extends to a torque tube foot positioned about the axle means.
A brake torque transfer assembly of a brake, comprising axle means upon which is mounted rotatably a wheel via bearing means, the brake comprising a torque tube having a torque tube radial flange and torque tube foot and maintained at a predetermined axial position adjacent a radial axle flange of said axle means, a piston housing connected with said torque tube, at least one disc member connected with said torque tube, at least a second disc member connected with said wheel, and the torque tube located nonrotatably relative to the axle means via a retention ring connected with the torque tube and engaging nonrotatably the axle flange of said axle means, the retention ring disposed radially outwardly relative to the axle flange and separate from the torque tube radial flange and torque tube foot, the retention ring being axially situated relative to the torque tube flange, and the retention ring having internal teeth means engaging teeth means at the circumference of said axle flange.
