ABSTRACT:
A continuously variable transmission system having a primary pulley, a secondary pulley, a driving belt disposed therebetween, and a torque converter disposed between an engine and the primary pulley. The pulleys each have discs movable by applying an hydraulic pressure to control the tension in the belt such that during acceleration from a stationary position the tension is temporarily increased to a level above a maximally allowable tension being determined on the basis of the statistic average of the expected number of revolutions at the end of the life of the belt.
