  • Electric power assist module for steering system
    Patent number: 7789191
    Abstract: An electric power assist module for a steering system has an integrated housing for accommodating the torque sensor, motor and electronic control unit. A helical gear train including a pinion gear, an intermediate gear and steering gear are provided to transfer the motion from the motor to an output shaft that is coupled to an input shaft by way of a torsion bar.

  • Torque sensor for electric power steering system
    Patent number: 7677114
    Abstract: A torque sensor, which is for an electric power steering system that has an output shaft for rotating in response to rotation of an input shaft, may include a first rotor for rotating with the input shaft, a second rotor for rotating with the output shaft, a first pinion gear mounted for rotating in response to rotation of the first rotor, a first magnet mounted for rotating with the first pinion gear, a second pinion gear mounted for rotating in response to rotation of the second rotor, a second magnet mounted for rotating with the second pinion gear, a first sensor positioned for sensing an angular position of the first magnet, and a second sensor positioned for sensing an angular position of the second magnet. The first rotor and the second rotor are mounted so that there can be relative rotation between the first rotor and the second rotor.
