Abstract
A torque-angle sensor includes a torque sensing unit, an angle sensing unit, and a PCB. The torque sensing unit includes a signal input rotor and a signal output rotor. The angle sensing unit includes a driving gear and a driven gear that is fitted round and fixed to one of the signal rotors. The PCB has a torque magnetic field generating unit, an input shaft signal collecting unit, and an output shaft signal collecting unit that sense a rotation angle and torque of the signal rotors. The PCB has an angle magnetic field generating unit and an angle collecting unit that sense a rotation angle of the driving gear and the driven gear. The torque magnetic field generating unit, the input shaft signal collecting unit, the output shaft signal collecting unit, the angle magnetic field generating unit, and the angle collecting unit are configured as coils formed by printed circuits.
