Abstract:
A multi-speed transmission comprising:an input shaft; an output shaft; first, second and third planetary gear sets each having first, second and third members; said input shaft being continuously interconnected with said first member of said third planetary gear set, said output shaft being continuously interconnected with said second member of said third planetary gear set; a first interconnecting member continuously interconnecting said first member of said first planetary gear set with said first member of said second planetary gear set; a second interconnecting member continuously interconnecting said second member of said first planetary gear set with said second member of said second planetary gear set and with said third member of said third planetary gear set; a first clutch selectively interconnecting said first member of said third planetary gear set, with a member of said first or second planetary gear sets; a second clutch selectively interconnecting said second member of said third planetary gear set, with said member of said first or second planetary gear sets connected with said first clutch; a first brake selectively interconnecting a transmission housing with another member of said first or second planetary gear set; a second brake selectively interconnecting said transmission housing with yet another member of said first or second planetary gear sets; and said first and second clutches and said first and second brakes being engaged in combinations of two to establish at least five forward speed ratios and a reverse speed ratio between said input shaft and said output shaft.
