摘要： A sensor-equipped wheel support bearing assembly capable of accurately detecting the load acting on the bearing assembly is provided. The sensor-equipped wheel support bearing assembly includes a sensor unit in an outer member that serves as a stationary member. The sensor unit includes a strain generating member, having two or more contact fixing segments to be fixed to the stationary member, and two or more sensors for detecting strain in the strain generating member. The contact fixing segments are spaced from each other in a direction circumferentially of the stationary member at the same axial positions. An estimating section is provided in the bearing assembly for estimating load thereon based on the difference between respective output signals from the sensors by calculating amplitudes of the output signals or values corresponding to such amplitudes from the difference between the respective output signals.

摘要： A vehicle wheel bearing apparatus has an outer member, an inner member double row rolling elements, and a constant velocity universal joint. A wheel hub of the inner member and an outer joint member of the constant velocity universal joint are axially separably connected. The outer joint member shoulder portion abuts against a caulked portion of the wheel hub. A cap is interposed between the caulked portion and the shoulder portion. The cap is press-formed from a steel plate and has a surface roughness of 0.63 Ra or less.
