Systems and methods are disclosed for aircraft wheels and brakes systems for use in, for example, an aircraft. In this regard, a damper for an axle may comprise a cylindrical canister defining a cavity configured to be inserted into a bore of the axle, the cavity at least partially filled with a damping material. The damper may act as a particle damper or a tuned mass damper to mitigate harmonic vibration of the axle and therefore the wheel and brake system.

An axle and wheel end assembly includes a tubular axle housing with an annular end surface. The axle and wheel end assembly also includes a spindle with an annular end surface welded to the annular end surface of the tubular axle housing at an attachment periphery. The axle and wheel end assembly further includes reinforcing structure fixed to the tubular axle housing and spindle. The reinforcing structure is located to encompass at least a portion of the attachment periphery.

Systems and methods are disclosed for aircraft wheels and brakes systems for use in, for example, an aircraft. In this regard, a damper for an axle may comprise a solid body defined by a cylindrical outside diameter (OD) surface and an elliptical inner surface configured to be inserted into a bore of the axle, the elliptical inner surface defining a void. The damper may comprise a varying thickness between the OD surface and the elliptical inner surface, the varying thickness including a minimum thickness along a major axis of the inner surface and a maximum thickness along a minor axis of the inner surface. The varying thickness may help to decouple a bending mode along the minor axis from the bending mode along the major axis.

An axle assembly having an axle, a brake spider and a bearing collar. The axle may have first and second transition regions. The first transition region may extend between first and second cylindrical portions of the axle. The second transition region may extend between second and third cylindrical portions of the axle. The brake spider may be disposed on the second cylindrical portion. The bearing collar may be disposed on the second transition region.

An axle beam comprises a hollow middle portion and a pair of hollow end portions. The hollow middle portion has a first corner-curved tapered arch cross-sectional shape. The pair of hollow end portions each have a substantially circular cross-sectional shape, and each extend from an opposite end of the middle portion. The hollow middle portion has a first wall thickness. The hollow end portions each have a second wall thickness that is larger than the first wall thickness.

Provided discloses an integrated axle assembly and structural assembly. The integrated axle assembly comprises an axle tube assembly extending in a first direction; a front support arm extending circumferentially from the axle tube assembly in a second direction perpendicular to the first direction for attachment to the frame; a rear support arm extending circumferentially from the axle tube assembly in a third direction away from the second direction for mounting a resilient assembly; and a brake base plate extending in a peripheral direction from the circumference of the axle tube assembly; the axle tube assembly, front bracket arm, rear bracket arm and brake base plate are molded in one piece, which improves the assembly efficiency.
