Abstract
A wheel hub assembly for motor vehicles, having a rotatable hub, a bearing unit in turn comprising a radially outer ring, a radially inner ring and a plurality of rolling bodies. The axial interface between the wheel hub assembly and a knuckle of a motor vehicle suspension provides at least one piezoelectric spacer configured to detect first mechanical vibrations coming from the components of the wheel hub assembly and to implement corrective action consisting of second mechanical vibrations of almost equal amplitude but with opposite direction and phase, so that the resultant of the first and second mechanical vibrations is close to zero.
