Abstract:
Provided herein is a carrier assembly for a continuously variable transmission having a plurality of balls, each ball having a ball axle, the ball axle defining a tiltable axis of rotation, a first traction ring assembly in contact with each ball, a second traction ring assembly in contact with each ball, the carrier assembly having a first carrier member substantially non-rotatable, a second carrier member configured to rotate relative to the first carrier member, and an axle capture member fixedly coupled to the first carrier member. The axle capture member is configured to selectively couple to one end of each ball axle.
