ABSTRACT:
Six forward speeds and one reverse speed may be realized with minimized length and weight of the transmission by employing two single pinion planetary gear sets and a double pinion planetary gear set. One planetary gear of the double pinion planetary gear set is interconnected with an adjacent second planetary gear of the second single pinion planetary gear set by a common planet carrier such that they may rotate independently, and at the same time, at least two ring gears are integrated so as to enhance strength in the axial direction.
