Abstract:
1. A hub-bearing assembly for the wheel of a motor vehicle, the hub forming integrally or being securely fixed to a radial flange to be fastened to a wheel, wherein, associated with the assembly is an optical measuring device mounted on a non-rotating part of the vehicle and axially facing an essentially radial optically reflecting surface secured to or integral with the flange for detecting real time variations of the axial position of the surface due to elastic deformation of the flange, the measuring device including emitter means for projecting a light radiation onto the reflecting surface and receiver means for receiving the light radiation reflected back by the reflecting surface, for detecting real time variations of the axial position of the surface due to elastic deformation of the flange caused by forces transmitted from the wheel to the hub flange.
