Electrical connection system between a wheel and a bearing-hub assembly, the wheel being mounted on an outer flange of the bearing-hub assembly, and the bearing-hub assembly comprising a rotationally fixed outer ring attached to the vehicle's suspension and an inner ring provided with a centering collar, an open frontal cavity defined in the said centering collar and an axial cavity opening into the said cavity; the connection system having a first connection cable attached to the inner ring and extending inside the axial cavity and the frontal cavity, a second connection cable integrated with the wheel, and a connection element associated with the said centering collar to provide electrical contact that can be selectively disconnected between the first cable and the second cable.

Electrical connection system between a wheel and a bearing-hub assembly

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 ().

Bearing assembly with rotation sensing device

The device (B) comprises a first non-rotatable ring () to be mounted adjacent to a non-rotatable race () of a bearing unit (A), and a second rotatable ring () to be coupled fast for rotation with a rotatable race () of the bearing unit (A). A first air passage () is formed through the first non-rotatable ring () and a second air passage () is formed through the second rotatable ring (). A sealing device () interposed between the first () and the second () ring, defines an intermediate chamber () communicating with the first () and the second () air passages.

Device for supplying pressurized air through the hub to the tire of a motor vehicle wheel

A bearing-suspension standard assembly for a motor vehicle wheel comprises a standard ( ) with an essentially cylindrical seat ( ), and a bearing unit ( ) with a non-rotating outer race ( ) fixedly mounted in the seat ( ). A cementing material ( ) is applied at one of the axial ends of the seat ( ) so as to lock the bearing unit ( ) in the seat ( ).
