A hub bearing unit for a vehicle wheel comprising a rotatable first ring connectable to the wheel and a non-rotatable second ring connectable to the vehicle chassis. The second ring includes a cylindrical portion and a radial flange for connection to the vehicle chassis. A bearing is radially disposed between the first and second rings enabling the first ring to rotate relative to the second ring about an axis of rotation. A self-contained non-rotatable measuring unit is secured fixedly relative to the second ring for measuring external forces applied to the wheel. The self-contained measuring unit comprises an annular carrier and a plurality of force sensors fixedly connected in the carrier in predetermined orientations relative to the axis of rotation. The force sensors are circumferentially spaced apart in the carrier. The carrier and force sensors are axially insertable and removable as a unit relative to the second ring. The carrier is molded of plastic, and the force sensors are integrally molded with the carrier. A heat shield is disposed between the measuring unit and the brakes of the wheel. <IMAGE> |
