摘要： A skew control system in a ball planetary continuously variable transmission, CVT, having a plurality of traction planets distributed radially about a main axle defining a longitudinal axis, each traction planet rotatable about a tiltable axle, a first traction ring and a second traction ring being in contact with the plurality of traction planets, the plurality of traction planets being interposed between the first traction ring and the second traction ring, and an idler assembly positioned radially inward of and in contact with each of the traction planets of the plurality of traction planets, the system comprising:
a first stator having a plurality of radial guide slots for engaging a first end of each tiltable axle of the plurality of traction planets;
a second stator having a plurality of radially offset guide slots for engaging a second end of each tiltable axle of the plurality of traction planets, the plurality of radially offset slots formed at an angle relative to the plurality of radial guide slots;
a stator driver assembly configured to rotate the first stator relative to the second stator to move each tiltable axle of the plurality of traction planets to a particular skew angle; and
a timing plate having a plurality of helical grooves for further engagement with one of the first end or the second end of each tiltable axle of the plurality of traction planets.A stator assembly for a continuously variable transmission (CVT) having a plurality of traction planet assemblies (142), the stator assembly comprising: a first stator (160) having a plurality of radial guide slots (161); a second stator (64) coaxial with the first stator (160), the first and second stators (160,164) configured to rotate relative to each other, the second stator (164) having a plurality of radially off-set guide slots (165); characterized in that the stator assembly further comprises: a reaction plate (162) coaxial with the first and second stators (160,164); a plurality of eccentric gears (168) coupled to the plate (162) and the first stator (160); and a stator driver (166) coupled to each of the eccentric gears (168), wherein the eccentric gears (168) are provided with a cam lobe (170) adapted to couple to the reaction plate (162); and wherein each eccentric gear (168) is provided with a reaction lobe (172) that is adapted to couple to the second stator (164); and wherein the cam lobe (170) is provided with a rotational center that is off-set from a rotational center of the reaction lobe (172).
