Abstract
Axial and rotational movement of the torque tube foot of an aircraft's disc brake assembly is restrained to substantially dampen or eliminate the short interval high frequency vibration previously experienced on brake application. Restraining means is employed to restrain the torque tube foot and includes an annular flange member mounted to the axle by an axle sleeve and positioned adjacent a first side of the torque tube foot to stop lateral movement of the torque tube foot in the direction of the first side. Wheel spacer means is also provided containing a cylindrical passage for mounting the wheel spacer means to the axle opposite the annular flange member and on the opposite side of the torque tube foot. The wheel spacer means also contains an annular portion extending radially outwardly from the wheel axis and the annular portion is positioned adjacent the second side of the torque tube foot to stop lateral movement of the torque tube foot in the direction of the second side such that the torque tube foot is restrained from moving in both axial and rotational directions relative to the axle. Vibration damage experienced to brake and landing gear components with brake assemblies of the prior design is avoided.
