摘要： A torque sensor has a torsion bar coaxially in alignment with input and output shafts, a ring shaped magnet fixed to an axial end of the input shaft, a pair of magnetic yokes fixed to an axial end of the output shaft, and a magnetic sensor for detecting magnetic flux density generated between the pair of magnetic yokes. Each of the magnetic yokes is provided with claws, which are circumferentially spaced at constant intervals, and whose number is equal to that of each of N and S poles alternately arranged circumferentially in the magnet. Each, center of the claws coincides with a boundary between immediately adjacent N and S poles of the magnet, when the torsion bar is not twisted. The magnetic sensor is inserted into an axial gap between the pair of magnetic yokes without contacting the magnetic yokes.

摘要： A torsion bar type torque sensor system is provided with the following: an elastic member that receives a torque and converts the torque to a torsion displacement; a multipolar ring magnet in which N poles and S poles are circumferentially and alternately magnetized; a pair of magnetic yoke halves disposed coaxially with the ring magnet; and a magnetometric sensor that detects magnetic flux generated between the pair of the magnetic yoke halves. The magnetometric sensor is made of a semiconductor that integrates a semiconductor magnetometric sensor, a non- volatile memory, a computation circuit, and an output circuit. This structure provides a torque sensor system that has an excellent maintainability.

摘要： A pair of magnetic flux collecting rings and a magnetic sensor are integrally covered by a molded resin to form a sub unit of a torque sensor. The pair of rings and sensors are integrated and are in contact with each other, i.e., the magnetic sensor is held in between respective magnetic flux collecting portions of the rings without any air gap formed therebetween. Magnetic flux collected by the rings can be detected by the magnetic sensor to a maximum degree, whereby the signal output of the magnetic sensor is enhanced and made stable.
