DRUM DRIVE FOR USE WITH MULTIPLE DISC BRAKES The drum drive (100, 200) comprises a generally annular-shaped drum (100, 200) which extends axially within an axial opening in an inboard half (140, 240) of a wheel (130, 230). The drum drive (100, 200) has end openings (112, 114; 212, 214) at opposite ends (102, 104; 202, 204) thereof which provide access to an interior axially extending opening (122, 222) of the drum drive (100, 200). An outboard end (104, 204) of the drum drive (100, 200) includes a radially extending flange (108, 208) which defines the associated end opening (114, 214) and provides a plurality of openings (118, 218) for receiving tie bolts (150, 250) that connect the drum drive (100, 200) with the wheel (130, 230). The drum drive (100, 200) includes a plurality of circumferentially spaced-apart, axially extending splines (128, 228) which extend radially inwardly from the interior surface of the drum drive (100, 200) and into the interior axially extending opening (122, 222). The splines (128, 228) are received within complementary-shaped openings (178, 278) of associated rotors (170, 270) in order to couple the rotors (170, 270) with the drum drive (100, 200) and wheel (130, 230).
