A wheel bearing assembly including inner and outer bearing rings, one of
which is intended to rotate and the other of which is intended to remain
stationary. The assembly also includes two sets of rolling elements
between the rings and in angular contact with tracks defined by the
rings. Each set of rolling elements is spaced in the direction of the
axis of rotation with each set of rolling elements retained by one of two
cages. The assembly further includes a sensing arrangement having at
least two annular encoders with alternate north and south magnetic poles
and at least two sensors operably associated with the encoders and each
serving to provide electrical signals generated by the passage of the
poles of the arranged encoder. One of the encoders is mounted on the
rotatable one of the bearing rings. The other encoder is mounted on one
of the cages and each of the sensors and encoders is disposed axially,
between the sets of rolling elements.
