Abstract
A bearing unit for a vehicle wheel hub is associated with a rotation sensing device and an electromagnetic inductive coupling. The rotation sensing device comprises an impulse ring () secured for rotation with the rotatable race () of the bearing unit by means of a rotatable annular carrier (), and a magnetic/electric transducer () mounted to the stationary race () of the bearing unit by means of a stationary annular carrier () and operatively facing the impulse ring (). The electromagnetic inductive coupling comprises a stationary coil () electrically connectable to a power supply () and carried by the stationary annular carrier (), and a rotatable coil () electrically connectable () to an electric or electronic device mounted on the wheel. The rotatable coil () is carried by the rotatable annular carrier () and is electromagnetically linked to the stationary coil ().
