Abstract: An electric-control belt-type continuous variable-speed transmission mechanism includes a driving-shaft, a driven-shaft, a driving-wheel, a driven-wheel, a transmission belt, a force-exerting device, an electric-control motor speed-adjusting device and an idle wheel. The electric-control motor speed-adjusting device operates along with the driving-wheel and the driven-wheel to dynamically control and adjust the overall configuration position of the transmission belt to thereby achieve effects of variable speeds, separation and restoration of dynamics. The idle wheel is rotatably disposed on the driving-shaft or the driven-shaft to axially support the transmission belt during the state of separate dynamics to prevent friction therebetween.

Abstract: An electrical control belt continuously variable transmission system controls a movable driving half-pulley or movable driven half-pulley initiatively, by changing a driving interval between the movable driving half-pulley and a fixed driving half-pulley or a driven interval between the movable driven half-pulley and a fixed driven half-pulley, respectively, depending on different statuses, in order to adjust a velocity ratio. By manipulating the movable driving half-pulley or the movable driven half-pulley, the system may further form a driving gap between the movable driving half-pulley and a transmission belt or a driven gap between the movable driven half-pulley and the transmission belt, such that the power is cut off. Clamping the movable driving half-pulley or the movable driven half-pulley to the transmission belt may restore the outputting of the power.
