A torque tube for an aircraft wheel and brake assembly is characterized by an annular, substantially cone-shaped, radially-extending backplate flange having a plurality of stiffening ribs which extend axially inboardly as radial extensions of various key surfaces, the key surfaces being adapted for engagement with alternating disks of a brake disk stack of the assembly. The stiffening ribs exhibit an axial dimension as may be defined by a pair of acute angles, a first acute angle establishing an outboard straight line surface of revolution which is continuous about the outboard end of the tube while a second acute angle establishes an inboard straight line surface of revolution in only the areas of the stiffening ribs. The backplate flange exhibits an axial dimension between the ribs as may be defined by a third acute angle which establishes a straight line surface of revolution between the adjacent ribs.

An improved configuration for a torque tube as may be applied to an aircraft wheel and brake assembly, the assembly comprising a multi-disk stack of braking elements wherein various ones of the disks are keyed for rotation with a wheel while others are keyed to the torque tube which is fixedly secured to a relatively stationary member of the assembly, the improvement comprising in combination: a cylindrical tube body having a central longitudinal axis, a substantially closed inboard end and an open outboard end, said body characterized by a plurality of radially extending key surfaces axially oriented and longitudinally extending from the inboard end toward the outboard end for engagement with various ones of a brake disk stack; and an annular, substantially cone-shaped radially extending backplate flange at the outboard end of the tube body characterized by a plurality of stiffening ribs which extend inboardly as radial extensions of at least some of the key surfaces, said ribs exhibiting an axial thickness dimension defined by a first acute angle having a center located at a point on the tube body axis such as to establish an outboard straight line surface of revolution of the cone-shaped outboard end and, a second acute angle having a center located at a point on the tube body axis such as to establish an inboard straight line surface of revolution which is intermittent and defines the inboard extent of each of the backplate ribs, said backplate flange exhibiting an axial thickness dimension between adjacent ribs defined by a third acute angle having a center located at a point on the tube body axis such as to establish an inboard straight line surface of revolution between the ribs.
