In a vehicle suspension assembly a sensorized system applied to a wheel hub unit, in which radially outer cylindrical surface of an outer ring of the wheel hub unit configured for coupling to a suspension upright or knuckle has four circumferential flats formed to be angularly spaced from each other on the radially outer lateral cylindrical surface, each flat delimiting a plane surface which extends axially over a pair of annular tracks for rolling bodies of the outer ring; each flat carries integrally a sensor module including a pair of extensometers positioned parallel to each other and each at the position of a respective annular track, orientated in a circumferential direction so as to extend along a circumferential development of the annular track; an electrical circuit picks up a signal from each sensor module and sends it to a data socket carried by the suspension upright or knuckle.

Sensorized suspension assembly for vehicles, including a wheel hub unit and a suspension upright or knuckle, and an associated method and wheel hub unit

A wheel hub unit having a central hub and a single central nut that includes respective shaped profiles radially oriented facing towards an axis (A) is provided. The wheel hub unit further includes an anti-unscrewing element interposed between the central hub and the single central nut to prevent accidental unscrewing of the single central nut. The anti-unscrewing element is provided with respective shaped profiles both radially oriented facing away from the axis (A) to engage with shaped profiles.
