Abstract:
1. A dual clutch transaxle comprising: a plurality of gears arranged in no more than seven gear planes; first and second input shafts; an output; and four sliding sleeves configured to actuate a plurality of couplers to selectively engage eight forward gear ratios and a reverse gear ratio and to permit shifting between all adjacent forward gear ratios with continuous transmission of torque through the transaxle, wherein the plurality of gears and the plurality of couplers includes a selectable power path between the first and second input shafts, wherein the power path constrains the first and second input shafts to rotate at a speed ratio not equal to one and does not constrain the speed of the output, and wherein the selectable power path is selected to establish the highest and the lowest of the eight forward gear ratios.
