Abstract:
1. A wheel support bearing assembly for rotatably supporting a vehicle wheel relative to a vehicle body, which comprises: an outer member having an inner periphery formed with a plurality of rolling surfaces; an inner member having an outer periphery formed with rolling surfaces held in fact-to-face relation with the above described rolling surface; a plurality of rows of rolling elements interposed between the rolling surface of the outer member and the rolling surface of the inner member; a vehicle body fitting flange to be fitted to a knuckle provided in an outer periphery of the outer member; and one or more sensor units including a strain generating member having two or more contact fixing segments adapted to be fixed to the outer periphery of the outer member in contact therewith, and a sensor fitted to the strain generating member and operable to detect a strain induced in the strain generating member, provided at an arcuately sectioned portion, formed to continue from a base end of an outboard oriented side face of the flange to the outer periphery of the outer member, or an outer peripheral surface portion of the outer member adjoining the articulately sectioned portion on an outboard side; the flange having a front elevational shape of a line symmetry with respect to a line segment perpendicular to a bearing axis or of a point symmetry about the bearing axis, wherein the one or more sensor units are enclosed with a tubular protective shroud, having a lip member made of an annular elastic element, that encloses an outer periphery of the outer member.
