Abstract
The differential engine comprises a motor, a torque conversion stage, and a loading mechanism. The torque conversion stage includes first and second differential stages which are coupled together with a pair of shafts, with the shafts rotating in opposite directions. The first differential stage comprises an input shaft which is coupled to the output shaft of the motor, and first and second output shafts which are coupled to the respective shafts. The second differential stage comprises an output coupled to the output drive shaft, and first and second input shafts which are coupled to the respective shafts. The second differential stage includes a gear mechanism which applies a rotational torque to the output drive shaft when a difference occurs between the rotational speeds for the shafts. The rotational speeds of the shafts are varied by loading one or both of the shafts.
