CONTINUOUSLY VARIABLE TRANSMISSION

摘要

A continuously variable transmission includes a plurality of planetary balls interposed between a first and second rotating elements on a shaft, an iris plate and a worm gear that tilt the planetary balls, a sun roller that includes a first sun roller that includes a first tubular section having first contact points with the planetary balls and a second tubular section having a smaller outer diameter than the first tubular section and is capable of relative rotation with respect to the shaft and a second sun roller that includes second contact points with the planetary balls and is capable of relative rotation with respect to the first sun roller on an outer peripheral surface of the second tubular section, and thrust bearings that are arranged between the first sun roller and the second sun roller and bear thrust loads transmitted from the planetary balls to the first sun roller and the second sun roller.
