Title:
POWER STEERING SYSTEM
Document Type and Number:
Japanese Patent JP2020093557
Kind Code:
A
Abstract:
To provide a power steering system making it possible to reduce a cost of manufacture.SOLUTION: A power steering system in accordance with the present invention includes a steering angle sensor 3 that detects an angle of rotation of a steering shaft, and a torque sensor 4 that detects torque occurring on the steering shaft. The steering angle sensor 3 detects magnetic fields which are induced by a first gear magnet 33 and a second gear magnet 34, by means of a first gear magnetic field detection unit 35 and a second gear magnetic field detection unit 36 which are mounted on a first loading surface 81 of a substrate 8. The torque sensor 4 detects a magnetic field which is induced by a torque sensor magnet 40, by means of a torque detection magnetism detection unit 45 mounted on a second loading surface 82.SELECTED DRAWING: Figure 2
