摘要： A variable transmission includes various powerpath layouts consisting in either; a single mode with approximately symmetrical reverse and forward speeds and includes an input shaft, one or two planetary gear sets, or a planetary gear set and a compound gear set when the RTS (ring-to-sun) ratio of the planetary gear set is not physically possible; or a dual mode with each mode being selected by closing a clutch/brake and releasing the other. A first up-speed planetary gear set on the input side of a variator, and a second planetary gear set on the output side of the variator, both configured to split the torque when drivingly engaged with a variator comprising, a first ring assembly, and a second ring assembly. Various up-speed ratio arrangements are shown that tend to increase the speeds and decrease the torque acting on the CVP, allowing a decrease in the variator size.
