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 a member of the third planetary gear set, said output shaft being continuously interconnected with another member of the third planetary gear set; a first interconnecting member continuously interconnecting said first member of said first planetary gear set 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; a transmission housing continuously interconnected with said third member of said first planetary gear set; a first clutch selectively interconnecting said first member of said third planetary gear set with said first member of said first and second planetary gear set; a second clutch selectively interconnecting said second member of said third planetary gear set with said third member of said second planetary gear set; a third clutch selectively interconnecting said third member of said third planetary gear set with a member of said second planetary gear set; a fourth clutch selectively interconnecting a member of said second planetary gear set with a member of said third planetary gear set, said members interconnected by said fourth clutch being different from the members interconnected by said first, second or third clutches; and said first, second, third and fourth clutches 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.
