Abstract
An arrangement for balancing axial forces in driver and driven clutches of a continuously variable transmission system that may include but is not limited to a pulley, a sheave mechanism, a driver clutch mechanism, or driver clutch, a driven pulley mechanism, a driven clutch mechanism, or driven clutch, and a shifting mechanism, servo, actuator mechanism, or actuator. The torque transmitted by the continuously variable transmission system is converted to axial forces acting upon belt. The forces in driver and driven clutches are balanced to minimize the force required for speed changes by shifting mechanism.
