Abstract:
A planetary transmission comprising:an input shaft adapted to be connected with a power source; an output shaft adapted to be connected to a drive mechanism; a stationary transmission housing; a first planetary gearset having first, second, and third members; a second planetary gearset having a first member continuously interconnected with said first member of said first planetary gearset through a first interconnecting member, a second member connected with a second member of said first planetary gearset through a second interconnecting member, and a third member; said output shaft being continuously interconnected with at least one member of said first or second planetary gearsets; a third planetary gearset having a first member continuously connected with said input shaft, a second member continuously connected with a stationary housing of said transmission, and a non-continuously interconnected third member, one of said first and third members being a faster rotating member and the other of said first and third members being a slower rotating member; a first torque transmitting mechanism operatively selectively connectable between said slower rotating member and at least one member of said first and second planetary gearsets; a second torque transmitting mechanism operatively selectively connectable between said faster rotating member and at least one member of said first and second planetary gearsets; third, fourth, and fifth torque transmitting mechanisms; and only said five torque transmitting mechanisms being selectively engaged in combinations of two to establish at least six forward speed ratios and one reverse speed ratio between said input shaft and said output shaft.
