ABSTRACT:
A variable speed clutch drive for light vehicles, e.g. motor bikes, snowmobiles, etc., responds to both engine speed and torque. The drive includes a conical pulley system of driver and driven pulleys coupled by a continuous V-belt. The driven pulley includes torque responsive means which utilize fixed and movable discs, the fixed disc containing radially arcuate apertures circularly disposed about its center of rotation. The discs are biased together by a spring system which includes a spring cover containing at least one integral cam for sliding contact with at least one aperture in the fixed disc.
