Sensor-Equipped Bearing for Wheel
First Claim
1. A sensor-equipped bearing for a wheel rotatably supporting the wheel relative to a vehicle body comprising:
- an outer member provided with a double-row raceway surface on an inner periphery thereof;
an inner member provided with raceway surfaces opposing to the raceway surfaces of the outer member, one of the outer and inner members serving as a stationary member;
double-row rolling elements interposed between the outer and inner raceway surfaces;
a sensor unit provided on the stationary member, and having a sensor fitting member fixed to a peripheral surface of the stationary member, and a plurality of strain sensors attached to the sensor fitting member for measuring a strain thereof, the sensor fitting member having at least two contact fixing portions fixed to the stationary member and at least one cut-off portion between the neighboring contact fixing portions, the strain sensor being attached to the cut-off portion.
