Abstract
A vehicle suspension system includes a vehicle body subframe, a wheel with a tire mounted upon a wheel hub assembly having a wheel spindle inside the wheel bearing. A wheel damping mass of ogival shape surrounds the outer race of the wheel bearing and is formed with a vertical slot whose length is perpendicular to the major diameter of the ogival cross section. The damping mass is formed with a pair of openings on each side of the vertical slot that accommodates a support assembly including a vertical shaft held by a shaft retainer intermediate the shaft ends, upper and lower bearings and centering springs located between the shaft retainer and each of the latter bearings. Damping fluid dissipates vibrational energy and may comprise a major component of the damping mass.
