Continuously variable transmission
Abstract:
A transmission for a work machine may include a first variator including a first input geared to a transmission input, a first output, and a first displacement. A second variator may include a second input geared to the transmission input, a second output, and a second displacement. The first displacement may be greater than the second displacement. A first planetary gear set may be in mechanical association with the second output, selectively coupled to a ground, and in mechanical association with a first gear. A second planetary gear set may be geared to the transmission input. A third planetary gear set may include a transmission output and may be in mechanical association with the second planetary gear set. A second gear may be in mechanical association with the third planetary gear set and may be in mesh with a third gear that is in mechanical association with the first output. The second gear may be in mesh with the first gear.
