Abstract
A continuously variable transmission includes a primary pulley, a secondary pulley, a drive belt wrapped around the pulleys at a variable radial position between discs of each pulley and a transmission control part for controlling a transmission torque ratio between a maximum and a minimum value (Rmax, Rmin), whose quotient defines a transmission ratio coverage, which is variable in dependence on the rotational speed of the primary pulley.
