Abstract:
Continuously variable transmission provided with a drive pulley and a driven pulley, each having at least one axially displaceable disk for pinching an endless transmission element between the disks of the pulleys, arranged so as to transmit torque between the pulleys, the transmission being controlled at least during full movement of the pulleys, such that the pinching force~of the drive pulley is dependent on the pinching force applied to the transmission element via the driven pulley, the pinching force applied to the transmission element is determined at least in part, as a function of a torque which is to be transmitted, wherein at least while the pulleys are at a standstill or during initial revolutions of the driven pulley prior to said full movement, the transmission is controlled such that the pinching force applied via the driven pulley at standstill or during initial revolutions of the drive pulley is at least substantially greater than the pinching force applied on said drive pulley in order to transmit a corresponding torque when controlling the transmission during said full movement.
