摘要： A continuously variable transmission (CVT) having a plurality of balls, each ball having a tiltable axis of rotation and in contact with a first traction ring and a second traction ring. The CVT includes a rotatable shaft aligned along a longitudinal axis of the CVT and positioned radially inward of the balls, the first traction ring, and the second traction ring; a carrier assembly operably coupled to each ball including a first carrier member coaxial to the shaft and a second carrier member operably coupled to the first carrier member; a first cam driver operably coupled to the first traction ring and the first carrier member and adapted to receive a rotational power; and a thrust bearing assembly coupled to the cam driver and the shaft. In one embodiment, the carrier assembly includes lubrication passage channels.
