1. A variable transmission comprising:
an input shaft; a variator (CVP) comprising a first ring assembly coupled to the input shaft, a carrier assembly comprising a plurality of tiltable variator balls drivingly engaged with the first ring assembly, and a second ring assembly drivingly engaged with the tiltable variator balls; and a first planetary gearset comprising a planet carrier drivingly engaged with the input shaft, a ring gear drivingly engaged with the second ring assembly of the variator, and a sun gear drivingly engaged with an output, wherein the planetary gearset is configured to split power of the input shaft between the variator and a mechanical path going directly to the output through the planetary gear set. |
