Abstract
A continuously variable transmission driven-pulley cam having a third cam surface which decreases the travel distance of the roller preventing the drive belt from dropping to a lower radius, thus preventing the transmission from going into a higher gear ratio upon inversion of torque transmitted to the driven pulley. The cam further includes a locking surface which prevents the roller from travelling axially to the cam, thus prevents the inner sheave from moving away from the outer sheave when the driven pulley is operating in the reverse direction. A continuously variable transmission driven-pulley cam roller assembly includes an inner roller and an outer roller wherein the diameters of the inner and outer rollers are different.
