1. A variable transmission comprising:
an input shaft; a variator comprising a first ring assembly, a second ring assembly, and a carrier assembly, wherein the second ring assembly is drivingly engaged to an output of the variable transmission; a planetary gear set comprising a sun gear drivingly engaged with the input shaft, a ring gear drivingly engaged with a variator carrier of the carrier assembly, and one or more planet gears on a planet carrier, the planet gears disposed in mechanical engagement between the sun gear and the ring gear; a first brake coupled to the ring gear and configured to hold the ring gear fixed when the first brake is engaged; and a second brake coupled to the planet carrier and the first ring assembly, and configured to hold the planet carrier fixed when the second brake is engaged. |
