Abstract
A wheel/hub assembly includes an axle shaft, a wheel, and a hub supporting the wheel on the axle shaft. The wheel/hub assembly has a target resonant frequency of vibration. A tuned mass-spring damper is vibrationally coupled to the wheel/hub assembly, and has a counteracting resonant frequency of vibration that is predetermined with reference to the target resonant frequency of vibration.

An apparatus comprising:
- a wheel/hub assembly including an axle shaft, a wheel, and a hub supporting the wheel on the axle shaft, the wheel/hub assembly having a target resonant frequency of vibration;
- and
- a tuned mass-spring damper vibrationally coupled to the wheel/hub assembly and having a counteracting resonant frequency of vibration that is predetermined with reference to the target resonant frequency of vibrations;
- wherein the damper is coupled to the wheel/hub assembly through a bearing on the axle shaft.
An apparatus for use with a wheel/hub assembly including an axle shaft, a wheel, and a hub supporting the wheel on the axle shaft, the wheel/hub assembly having a target resonant frequency of vibration, the apparatus comprising:
- a tuned mass-spring damper comprising:
- an inner layer of rubber;
- and
- an outer layer of rubber that overlies and is bonded to the inner layer;
- wherein the inner layer is mounted on an outer race of a bearing on the axle shaft.
