Abstract: A gear type automated torque converter used to provide a continuously variable minimum torque required in a transmission system subject to the changing of the loading is provided. The gear type automated torque converter includes a torque changing main unit formed of a drive gear set to receive an input power, the drive gear set including a differential gear system, a left gear at the left side, and a right gear at the right side; and a feedback gear mechanism formed of a plurality of feedback gear sets arranged in pair in force couples, the feedback gear sets each including a differential gear system, a left gear at the left side, and a right gear at the right side, the output rotational speed of the feedback gear mechanism and the input rotational speed of the torque changing main unit are equal, enabling the power at the feedback gear mechanism be fed back to the torque main unit through a converter.
