ABSTRACT:
An electric damp controlled three-end shaft differential transmission including a revolving electro-mechanical installation disposed between both differential output ends to create vortex power generation effects or generator effects in differential operation to output power for producing counter torque damp; or when two revolving electro-mechanical installations being respectively adapted to both differential output ends, the higher power generated by the revolving electro-mechanical installation with higher power generation voltage drives the other revolving electro-mechanical installation with lower power generation voltage to regulate and control the torque ratio between both differential output ends.
