ROTATIONAL POSITION DETECTOR FOR WHEEL, AND WHEEL SIX-COMPONENT FORCE MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a rotational position detector for a wheel that detects the rotational position of a wheel by a low-cost and simple configuration, and to provide a wheel six partial output measuring device for calculating outer force applied to the wheel based on the detection value of a six-component force load meter and that of the rotational position of the wheel. SOLUTION: The rotational position detector for a wheel comprises a plurality of magnetic sensor units 80-87 provided with a first interval on the circumference with the rotary axis of the wheel 3 at the side of a wheel rim 60 as a center; a plurality of magnets 90 provided at a second interval that is shorter than the first interval in the range of the first interval at a position that opposes the magnetic sensor units 80-87 when the wheel 3 is rotated in a non-magnetic member 70 mounted to a knuckle for rotatably retaining a hub 30 where a wheel disk 61 is clamped; and a rotational position gripping means for gripping the rotational position of the wheel 3, based on the counted value of the number of detections of the magnets 90 by the plurality of magnetic sensor units 80-87.
