Working Mechanism CVT At Low Rpm

In reandah speed, the force on spring driven movable larger than centrifugal force acting on the weight roller. After the movable driven face narrows then pressed v-belt drive toward the outside so that the radius of v-belt drive to be great. While in the movable drive face, v-belt drive radius to be reduced.

Working Mechanism CVT At high Rpm

At high speeds, centrifugal force on the weight roller to work so that the movable drive face narrowed. At the same time, the movable drive face narrowed then pressing the v-belt drive towards the outside so the radius v-belt drive be big. While on the movable driven face radius v-belt drive is reduced.

Working Mechanism kickdown On CVT

On the face there are working mechanisms driven mechanism called kickdown mechanism, this mechanism automatically increases when the acceleration reduction ratio arrived - arrived (driving uphill). When acceleration arrived - arrived to work at the face through the torque cam driven, torque-driven cam face pressed into the appropriate parts of the arrow (1), the radius increases driven face in the direction of the arrow (2), reduction ratio increases so that the thrust force add too.
