Claim Text:
1. A drive pulley for a continuously variable transmission comprising: a fixed sheave; a movable sheave axially movable relative to the fixed sheave, the movable sheave being rotationally fixed relative to the fixed sheave; and at least one centrifugal actuator including an arm pivotally connected to one of the movable sheave and a portion of the drive pulley axially and rotationally fixed the fixed sheave at a first pivot axis, the arm pivoting away from the one of the movable sheave and the portion of the drive pulley about the first pivot axis as a speed of rotation of the drive pulley increases, the arm pushing against another one of the movable sheave and the portion of the drive pulley as the arm pivots away from the one of the movable sheave and the portion of the drive pulley, thereby moving the movable sheave axially toward the fixed sheave, the arm being movable relative to the first pivot axis by pivoting the arm about a second pivot axis, the second pivot axis being offset from the first pivot axis, the second pivot axis being parallel to the first pivot axis, the arm having a head portion and a tail portion, the first pivot axis passing through the head portion, the tail portion having a point therein remaining at a constant distance from the first pivot axis as the arm moves relative to the first pivot axis by pivoting the arm about the second pivot axis.
