SENSOR-EQUIPPED BEARING FOR WHEEL

摘要

A sensor equipped wheel support bearing assembly, in which the load imposed on the wheel support bearing assembly or a tire tread of a wheel tire can be accurately detected without being affected by the rolling elements, includes rolling elements interposed between plural opposed rolling surfaces defined in outer and inner members. One of the outer and inner members that serves as a stationary member is provided with one or more sensor unit. The sensor unit includes a strain generating member, having two or more contact fixing segments fixed to the stationary member, and a sensor for detecting such strain. The strain generating member in the sensor unit is arranged at a position departing from a line passing through a center of the rolling elements and extending in a direction defined by the rolling element contact angle.
