A bearing unit having an axis of rotation (X) for a wheel hub assembly for motor vehicles includes stationary radially outer ring, a rotatable wheel hub or first radially inner ring, a rotatable second radially inner ring having an axially external first axial contact edge, an axially internal second axial contact edge having a radially external first contact surface configured to abut a surface of the first radially inner ring, a radially internal second contact surface, and a relief groove interposed radially between the first contact surface and the second contact surface, two rows of rolling bodies interposed between the radially outer ring and the second radially inner ring, and a joint including a bell, the second contact surface contacting a surface of the bell and axial locks the radially inner ring, and the relief groove reducing contact between the second contact edge and the surface of the bell.

Optimized wheel hub assembly

A user interface actuator for a pilot-by-wire system comprises a rotary electric motor having an output shaft suitable to be connected to a rotating user interface, a first absolute angular sensor for detecting in direct drive the number of revolutions of the shaft and a second absolute angular sensor redundant with respect to the first absolute angular sensor.

User interface actuator for a pilot-by-wire system

A wheel hub having an axis of symmetry and including a flange transverse to the axis of symmetry and provided with a plurality of fixing holes for attaching a wheel, a tubular body extending axially from the flange for supporting a rolling bearing, and a centering device arranged on a side of the flange opposite to that of the tubular body and in a position concentric with the axis of symmetry of the wheel hub, for retaining a wheel rim or a brake disc. The centering device being provided with a given number of flattened areas extending circumferentially and axially on a respective continuous tubular body projecting axially from the flange.
