The pulley technique in the CVT is made up of two pulleys, 1 connected to the motor and the opposite for the transmission. The 2 pulleys are linked by a belt or chain. The pulleys are formed like cones, and their diameters may be modified to alter the equipment ratio. https://gunnerqwurn.blue-blogs.com/41506071/getting-my-gearbox-cvt-to-work
