SENSOR-EQUIPPED WHEEL BEARING

摘要

A sensor equipped wheel support bearing assembly having good assemblability with a compact structure and capable of accurately detecting load acting on a bearing of a vehicle wheel is provided. One of an outer member and an inner member that serves as a stationary member has a vehicle body fitting flange to be fitted to a knuckle. One or more load detecting sensor unit is provided on the stationary member and includes a strain generating member having two or more contact fixing segments fixed to the stationary member, and one or more sensors fitted to the strain generating member for detecting a strain occurring in the strain generating member. A circuit fixing stay is provided on a side face of the vehicle body fitting flange and a calculation processing circuit is fitted to this stay for calculating and processing an output signal of the sensor.
