Title:
CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2017/178821
Kind Code:
A3
Abstract:
The invention relates to a continuously variable transmission (CVT) comprising a ratio varying unit and a compound epicyclic gear set. The ratio varying unit has a rotating first side and a rotating second side, the rotational axes of the first and second sides being coaxial. The compound epicyclic gear set comprises a first set of planets, being rotationally mounted within a carrier and meshing with a sun gear. The epicyclic gear set also has a first annulus gear and a second set of planets; the second set of planets also being rotationally mounted within the carrier and meshing with a second annulus gear. One of the first or second rotating sides of the ratio varying unit is coupled to the carrier and the other of the first or second rotating sides of the ratio varying unit is coupled to the sun gear.
