Patent ID: 7037232

Claim:
A multiple-speed transmission for an automotive vehicle comprising: an input section; an output section; a speed-reducing planetary gearset including a first rotating element having a first primary speed ratio slower than the input section, a second rotating element drivingly connected to the input section and having a second primary speed ratio faster than the first primary speed ratio in the same direction as the first rotating element, and a third rotating element held against rotation; a speed-shifting planetary gearset including a first rotating member, a second rotating member drivingly connected to the output section, a third rotating member, a fourth rotating member, a fifth rotating member, and a sixth rotating member, for taking a rotation state determined by a combination of rotations of two of the six rotating members of the speed-shifting planetary gearset, where each of the six rotating members of the speed-shifting planetary gearset has a rotation speed that monotonously varies in order of the first rotating member, the second rotating member, the third rotating member, the sixth rotating member, and the two members of the fourth rotating member and the fifth rotating member; a first clutch for selectively drivingly connecting and disconnecting the first rotating element of the speed-reducing planetary gearset and the first rotating member of the speed-shifting planetary gearset; a second clutch for selectively drivingly connecting and disconnecting the first rotating element of the speed-reducing planetary gearset and the fourth rotating member of the speed-shifting planetary gearset; a third clutch for selectively drivingly connecting and disconnecting the second rotating element of the speed-reducing planetary gearset and the third rotating member of the speed-shifting planetary gearset; a first brake operable to hold selectively against rotation the third rotating member of the speed-shifting planetary gearset; a second brake operable to hold selectively against rotation the fifth rotating member of the speed-shifting planetary gearset; and a third brake operable to hold selectively against rotation the sixth rotating member of the speed-shifting planetary gearset.
