Abstract
A variable transmission includes driving and driven cone discs respectively having two movable and pressing cone discs; a pressing mechanism having an end surface cam pressing mechanism arranged on the back of one pressing cone disc of the driving and driven pressing cone discs; a ratio control mechanism having a ratio control shaft, hollow screws and nuts, arranged on the backs of the driving and driven movable cone discs and adopt ball screw structures or sliding screw structures; the ratio control shaft and a constant ratio transmission mechanism enable the conversion relationships between the rotation of the speed control shaft and the axial sliding of the driving and driven movable cone discs are be equal to each other to ensure the transmission shafts of the driving and driven movable cone discs move axially and synchronously at the same speed and in the same direction.
