Integrated aircraft wheel, brake and axle
First Claim
1. Aircraft wheels and brakes in combination with a multiaxle bogie beam having at least two brake axles connected operatively with a strut of an aircraft, comprising a piston housing located about each respective brake axle, a plurality of stator discs disposed about a respective brake axle so as to transfer braking torque to the respective brake axle, a plurality of rotor discs, a wheel mounted rotatably on the respective brake axle and connected with the rotor discs, at least one brake torque take-out arm separate from and connected non-rotatably with the respective brake axle, the brake torque take-out arm being connected with a brake rod connected with the strut of an aircraft wherein the brake rod and strut are separate from and located exteriorly the respective brake axle, and connection means between the torque take-out arm and respective brake axle in order to effect the non-rotatable connection therebetween.

Abstract
The integrated aircraft wheel, brake and axle comprises a hollow wheel and brake axle (16, 116) having longitudinal splines (17, 117) about its outer periphery, the longitudinal splines (17, 117) engaging splines (62, 162) of a piston housing (60, 160) to effect a non-rotatable connection therebetween. In one embodiment, the piston housing (60) is connected by way of a spline sleeve (70) with a backing plate (80). A wheel (45) is rotatably mounted upon an end of the brake axle (16) and includes a drum drive (52) which extends axially to a drum drive end (52A) having at its inner diameter a bearing assembly (55, 56) between the drum drive end (52A) and an outer diameter of the piston housing (60). In another embodiment, the drum drive (152) may include a thrust flange (151) engaging a rotor disc backing plate (192A). A plurality of stator discs (90, 190) are connected non-rotatably with the spline sleeve (70, 170) and splines (17, 117) of the brake axle (16, 116) and a plurality of rotors (92, 192) are connected with a plurality of splines (53, 153) attached to the inner diameter of the drum drive (52, 152). The brake axle(s) (16, 116) is connected non-rotatably to a brake torque take-out arm(s) (18, 22, 118) which is connected with a brake rod(s) (20, 24) for attachment to a strut (12) of the aircraft Either a pair of brake torque take-out arms (22) and brake rods (24) or a single brake torque take-out arm (18, 118) and brake rod (20) aligned axially with the strut (12) may be utilized with an axle.
