Integrated aircraft wheel, brake and axle for all-electric aircraft braking system
First Claim
1. A wheel and brake assembly comprising a tubular axle, a wheel having a web and an outer peripheral rim, a wheel hub rotatably mounted interiorly of the tubular axle and accessible at an axial end thereof for mounting of the wheel thereto, and a brake disk stack having front and rear axial ends and including alternating rotor and stator disks mounted with respect to the axle and wheel for relative axial movement, each rotor disk being coupled to the wheel for rotation therewith and each stator disk being coupled to the axle for support against rotation, and wherein the wheel web has mounted thereto a plurality of disk engaging members providing for the transfer of force from the brake disk stack to the wheel web whereby the wheel web functions as a back pressure member for applying force to the outboard end of the disk stack.

Abstract
An integrated wheel, brake and axle structure for an aircraft comprises a tubular axle, and a wheel hub rotatably mounted interiorly of the tubular axle and accessible at an axial end thereof for mounting of a wheel thereto. A brake disk stack, having front and rear axial ends, includes alternating rotor and stator disks mounted with respect to the wheel support and wheel for relative axial movement. Each rotor disk is coupled to the wheel for rotation therewith and each stator disk is coupled to the axle for support against rotation. In such arrangement, the wheel web functions as a back pressure member for applying force to the outboard end of the disk stack. A cooling fan is provided interior of the axle for generating a cooling flow of air across the brake disk stack.
