Abstract:
1. A sensor incorporated wheel support bearing assembly for rotatably supporting a vehicle wheel relative to an automotive body structure, which assembly comprises: an outer member having an inner periphery formed with double row rolling surfaces defined therein, an inner member formed with rolling surfaces in face-to-face relation with the rolling surfaces in the outer member, a plurality of rows of rolling elements interposed between those rolling surfaces; and a sensor unit mounted on one of the outer member and the inner member, which is a stationary member, the sensor unit including a sensor mounting member and a strain sensor fitted to the sensor mounting member; in which the sensor mounting member has a plurality of contact fixing portions that are fixed to at least two locations spaced from each other in a direction circumferentially of the stationary member; in which a cutout is provided in the stationary member at least one location, corresponding to an intermediate portion between the plural neighboring contact fixing portions of the sensor mounting member, so as to extend in a direction axially thereof; and in which the strain sensor is arranged at least one location intermediate between the neighboring contact fixing portions.
