Abstract

　少ないセンサ数で、ヒステリシスの影響を受けることなく、どのような荷重条件においても、車輪にかかる荷重を正確に検出できるセンサ付車輪用軸受を提供する。車輪用軸受は、外方部材１と内方部材２の対向し合う複列の転走面３，４間に転動体５を介在させたものである。外方部材１と内方部材２のうち固定側部材の外径面に、２つのセンサユニット２０からなるセンサユニット対１９を設ける。両センサユニット２０は、前記固定側部材の円周方向１８０度の位相差をなす位置に配置する。センサユニット２０は、固定側部材外径面への２つ以上の接触固定部を有する歪み発生部材と、同部材の歪みを検出するセンサを有する。両センサユニット２０のセンサ出力信号の差分により、径方向荷重推定手段３１で径方向荷重を、また前記センサ出力信号の和により、軸方向荷重推定手段３２で軸方向荷重を推定する。
