Abstract
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 first and second rollers rotationally connected to one of the movable sheave and the spider. The first roller rolls along the other one of the movable sheave and the spider as the movable sheave moves axially. The second roller rolls 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.
