ABSTRACT:
A four-element, two-freedom-degree planetary gear mechanism is constructed by arraying four input/output elements of a sun gear S1, a ring gear R, a carrier C and a sun gear S2in a alignment chart. One of the two elements R and C arrayed on the inner side is assigned to the input In from an engine whereas the other is assigned to the output Out to the drive shaft, and the two outer elements S1and S2are connected to motor-generators MGi and MGo, respectively. As a result, the torque for the motor-generators to bear can be made lower than the engine output, and the energy to pass through the motor-generators is made lower to improve the transmission efficiency of the drivetrain.
