ABSTRACT:
A variable ratio drive pulley designed for use in a belt drive transmission of a snowmobile includes fixed and movable flanges, the movable flange being controlled by centrifugally responsive thrust means employing pivoted weighted levers cooperating with shaped cam surfaces. The dynamic response of the pulley can be adjusted in a simple manner by abutment means supporting the ramps on which the cam surfaces are provided, these abutment means being accessible for adjustment from the exterior of the pulley.
