Abstract:
1. A multi-speed transmission comprising: an input member and an output member disposed in a housing; a first planetary gear set, a second planetary gear set, a third planetary gear set, and a fourth planetary gear set, each planetary gear set being disposed within the housing and including a sun gear, a planet carrier, and a ring gear; six control elements, at least one control element operably coupled to each of the planetary gear sets, selectively engagable to create a set of different gear ratios between the input member and the output member, the set of different gear ratios including at least ten forward gear ratios and at least one reverse gear ratio; a first intermediate coupling member continuously connected to the planet carrier of the fourth planetary gear set; a second intermediate coupling continuously connected to at least one of the first and second planetary gear sets; a third intermediate coupling member continuously connected to the sun gears of the third and fourth planetary gear sets; a first of the six control elements selectively connecting at least one of the sun gear, the planet carrier, and the ring gear of the first planetary gear set with the first intermediate coupling member; and a second of the six control elements selectively connecting at least one of the sun gear, the planet carrier, and the ring gear of the first planetary gear set with the third intermediate coupling member; wherein the input member is continuously connected to the sun gear of the first planetary gear set.
