CONTINUOUSLY VARIABLE TRANSMISSION DRIVE PULLEY

摘要

A drive pulley for a continuously variable transmission includes a fixed sheave and a movable sheave rotationally fixed relative to the fixed sheave. A housing is axially and rotationally fixed relative to the fixed sheave. At least one centrifugal actuator includes an arm pivotally connected to one of the movable sheave and the housing of the fixed sheave at a first pivot axis. The arm pivots away from the one of the movable sheave and the housing about the first pivot axis as a speed of rotation of the drive pulley increases and pushes against another one of the movable sheave and the housing thereby moving the movable sheave axially toward the fixed sheave. The arm is movable relative to the first pivot axis by pivoting the at least one arm about a second pivot axis. The second pivot axis is offset from the first pivot axis.
