Ratio Changing the Continuously Variable Transmission 2004-01-1634
The ratio changing mechanics of the continuously variable transmissions are developed. The lever analogy of gear sets, comparison to step gear transmission mechanics, differential calculus analysis, and the step gear ratio changing equations are used. Power on up-shifts, power on downshifts, power off up-shifts, and power off downshifts are analyzed. Approaches to minimize the disturbances are considered.
