Relative rotation angle displacement detecting device, the torque detecting device and torque control device using the same detection equipment, as well as a vehicle equipped with the same control device

摘要

application can detect the relative rotation angle displacement of the relative rotational movement possible pair of rotary members with a simple structure, providing relative rotation angle displacement detection device. One in the circumferential direction of the rotation axis of the pair of rotary members to rotate relative to the permanent magnet poles polarity alternately circumferentially arranged in a different manner provided, the other rotary member, and a ring body , placing the induction ring having a plurality of projections projecting from the ring body in the radial direction. Further, the ring body of the induction ring, placing a plurality of magnetic sensors. It was opposed to a part of the ring body, and the first opposing portion for receiving a portion of the magnetic flux of the ring body, a part of the magnetic flux of said ring body at a position spaced in the circumferential direction of the rotation axis from the first opposing portions the second opposing portion for receiving, regardless of the rotation around the rotation axis of the permanent magnet and the induction ring to fix the circumferential direction of the relative position of said rotation axis.
