Abstract:
A torque detector for detecting input torque from the amount of relative rotation of an input shaft, linking with a steering wheel, and an output shaft linking with wheels, and supplying the detected signal to a controller, said torque detector comprising:a conversion member having at least one groove, said conversion member arranged about outer circumferences of the input shaft and the output shaft to convert the amount of relative rotation of the input and output shafts to a displacement in an axial direction, said at least one groove being structured and arranged to receive at least one pin, said at least one pin coupled to the output shaft and being slidably fitted thereon; an annular-shaped ring member formed of a magnet and secured on the outer circumference of said conversion member; and a plurality of magnetically sensitive devices arranged at intervals around said ring member to oppose each other, wherein said magnetically sensitive device detects the amount of travel of said ring member in the axial direction and supplying the detected amount as a voltage signal to the controller.
