Abstract
A continuously adjustable transmission has two sets of cone pulleys disposed concentrically with respect to each other on a transmission input shaft. Between the two sets of cone pulleys a rigid ring acts as a torque transmitting member for transmitting torque from one set of cone pulleys to the other. This arrangement provides a compact and lightweight transmission producing the best transmission efficiency levels, especially at high and medium gear ratios.
