Abstract
A drive force distribution apparatus is provided with an input shaft, first and second output shafts, a first epicyclic gear group, a second epicyclic gear group and a motor/generator. The first epicyclic gear group has two degrees of freedom, with the first epicyclic gear group including a first gear coupled to the input shaft, a second gear coupled to the first output shaft and a third gear. The second epicyclic gear group has two degrees of freedom, with the second epicyclic gear group including a first gear coupled to the input shaft, a second gear coupled to the second output shaft and a third gear. The motor/generator is operatively coupled to the third gears of the first and second epicyclic gear groups so that mutually different drive forces are transmitted from the motor/generator to the first and second epicyclic gear groups.
