ABSTRACT:
The apparatus of the present invention comprises a torque amplifier assembly having a first shaft and a second shaft, each with complementary direct drive gears and complementary torque amplifier gears thereon. The torque amplifier and direct drive gears are rotatable on the first shaft, but may be independently coupled to the first shaft by means of a torque amplifier clutch or a direct drive clutch. In order to stop the rotation of the torque amplifier and direct drive gears, the clutches for both the direct drive gear and the torque amplifier gear are simultaneoulsy actuated to cause them both to be engaged to the first shaft. The resulting difference in gear ratios causes the two shafts to stop rotating.
