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.

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.

A wheel axle suspension of a vehicle, comprises an axle body having a rectangular cross section, a flexible trailing arm extending in a longitudinal direction of the vehicle and crossing the axle body substantially perpendicular, and at least one clamping strap assembly for clamping the axle body and the trailing arm together. The trailing arm has a front spring portion extending in the longitudinal direction of the vehicle and is provided with an axle seating portion adjoining the front spring portion at a rear end thereof. The axle seating portion comprises a longitudinal portion extending substantially in line with the front spring portion, and a downwardly extending portion extending substantially perpendicular to the longitudinal portion. The axle body is received in the axle seating portion with the upper side and rear side facing the longitudinal portion and the downwardly extending portion respectively. The axle seating portion of the trailing arm has an axle body facing surface having three engagement areas engaging the axle body respectively at the front upper corner, the rear upper corner and at a region at or adjacent the lower rear corner of the axle body. Between said engagement areas there is a clearance between the axle body facing surface of the axle seating portion and the upper side and rear side of the axle body.

A non-driven axle for a vehicle or a trailer is provided. The non-driven axle includes a first arm portion, a second arm portion, and a central portion. The first arm portion is for rotatably mounting a first wheel hub. The second arm portion is for rotatably mounting a second wheel hub. The second arm portion is on an axial end of the central portion opposite the first arm portion. The central portion is between the first arm portion and the second arm portion and may be substantially arch-shaped or substantially ring-shaped. The substantially arch-shaped central portion includes a main portion and a radially inner portion. The substantially ring-shaped central portion includes a main portion and an inner portion. The non-driven axle reduces a weight of a vehicle or trailer while capable of being lifted without interfering with an operation of a drive axle.

A wheel bearing arrangement, in particular wheel bearing arrangement for utility vehicles, comprising a hollow body unit, a securing unit and a stator unit, wherein the hollow body unit has a maximum extent in an axial direction, a pressure space extending substantially in the axial direction, and an end section, wherein the securing unit is secured to the end section, wherein the stator unit is secured to the securing unit, and wherein the stator unit has attachment and sealing means, by means of which a rotor unit can be made to bear against the wheel bearing arrangement in a way which is air-tight and rotatable relative to the stator unit.
