centrigal force via ramps inside the primary clutch squeze the cones together, puting force onto the belt. At high rpm, then the cones are as close the belt gets tighter- this tension spreads the cones of the secondary unit, making the effective Pulley diameter of the primary larger then that of the secondary, creating overdrive.
Great concept but your would need to do extensive testing with different ramps, weights and springs to find a good mix  |
Thats cool, I was not aware that a mechanical method was used to vary the pulley size. I figured that it would be electronically controlled via some sort of electro-hydraulic mechanism.
