Integrated aircraft wheel, brake and axle for all-electric aircraft braking system

摘要

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.
