CONTINUOUSLY VARIABLE TRANSMISSION DRIVE PULLEY

摘要

A drive pulley for a CVT has a fixed sheave, a movable sheave, a spider, a biasing member biasing the movable sheave axially away from the fixed sheave, at least one centrifugal actuator and at least one roller assembly. The at least one roller assembly has first and second rollers rotationally connected to one of the movable sheave and the spider and abutting another one of the movable sheave and the spider, the first roller rolling along the other one of the movable sheave and the spider as the movable sheave moves axially, the second roller rolling along the other one of the movable sheave and the spider as the movable sheave moves axially. The first and second rollers transfer torque between the movable sheave and the spider.
