Abstract:
A vehicle suspension system includes a vehicle body subframe (37), a wheel (11) with a tire mounted upon a wheel hub assembly having a wheel spindle (27) inside the wheel bearing (22D). A wheel damping mass (21) of ogival shape surrounds the outer face of the wheel bearing and is formed with a vertical slot (21A) whose length is perpendicular to the major diameter of the ogival cross section. The damping mass is formed with a pair of openings (47) on each side of the vertical slot that each accommodate a support assembly including a vertical shaft (45) held by a shaft retainer (44) intermediate the shaft ends, upper and lower bearings (43) and centering springs (42) located between the shaft retainer and each of the latter bearings. Damping fluid (60) may dissipate vibrational energy and may comprise a major component of the damping mass (21).
