ABSTRACT:
In known V-belt automatic variable power transmissions the change in the gear ratio as a function of angular velocity or the number of revolutions at full throttle at high loads is a compromise between the desired performance of the vehicle and fuel consumption, emission, noise nuisance considerations. The invention obolishes this compromise by making the gear ratio constant in a determined region or range of angular velocities around the original change gear ratio and number of revolutions relationship. In a preferred embodiment this is achieved by the shape of the cam surfaces of the centrifugal weights which surfaces are almost straight over a determined portion thereof.
