Abstract
A hybrid vehicle is powered by a drive system including an internal combustion engine, a generator and an electric motor. A differential gear unit includes at least three elements, the first connecting to the generator, the second connecting to a first gear and the third connecting the internal combustion engine. A second gear is connected to the output shaft of the electric motor. A counter shaft carries a third gear meshing with the first and second gears and connects to the differential gear unit. The internal combustion engine, differential gear unit and generator are aligned on a first axis, the electric motor is aligned on a second axis parallel to the first axis, the counter shaft is aligned on a third axis parallel to the first and second axes, the differential gear unit is aligned on a fourth axis parallel to the first, second and third axes, and the third axis is disposed inside of a triangle defined by the first, second and fourth axes when viewed on end.
