Torque pads for aircraft brake systems and aircraft brake system including same

An aircraft brake system ( 42 ) includes a torque tube ( 44 ), a plurality of spaced stators ( 48 ) mounted on the torque tube ( 44 ), a wheel ( 40 ) surrounding the torque tube ( 44 ) and a plurality of rotors ( 50 ) connected to the wheel ( 40 ) and projecting into the spaces between adjacent ones of the stators ( 48 ). A backing plate ( 52 ) mounted on the torque tube ( 44 ) has a first side ( 54 ) facing the rotors ( 50 ) and a second side ( 56 ) facing away from the rotors ( 50 ), and the second side ( 56 ) includes a plurality of keyways ( 58 ). A plurality of torque pads ( 10, 70, 100, 120 ) are connected to the torque tube ( 44 ), each having a body ( 12, 72, 102, 122 ) with a first surface ( 14, 74, 104, 124 ) contacting the second side ( 56 ) of the backing plate ( 52 ) and at least one key ( 22, 82, 112, 114, 130, 132 ) projecting from the first surface ( 14, 74, 104, 124 ) into one of the plurality of keyways ( 58 ). Also a torque pad ( 10, 70, 100, 120 ) and a method of connecting a backing plate to a torque tube.
