Continuously variable speed drives (CVT) have improved performance over all shift ratios using an improved flyweight (camweight) that enhances power transfer for higher shift ratios (slower vehicle speeds) without compromising efficiency or performance at smaller shift ratios. Prior art CVTs characteristically have some belt slippage, and attendant power waste and excess wear, when operating with higher shift ratios. The prior art deficiency is due to a tendency of the prior art flyweights not to cause sufficient side forces (axial forces) on the belt at...
1. An improved flyweight for use in a CVT,the flyweight having a head symmetrically surrounding a pivot with a rotational axis passing through center of said pivot, an arm extending away from said pivot, having a cam surface, and having a center-of-mass (COM), and a plumb line dropped from said center of said pivot of said flyweight when said flyweight is statically suspended by said pivot, where angles measured from said plumb line start at zero degrees for directions along said plumb line in the direction of said arm and increase in the direction of sa...
