ABSTRACT:
A continuously variable transmission and a drive train having a continuously variable transmission. The transmission is provided with a drive pulley and a driven pulley, each having at least one axially displaceable disc in order to be able to pinch an endless transmission element between the discs of a pulley, the transmission being controlled, at least during full movement of the pulleys, in such a way that the pinching force of the drive pulley is dependent on the pinching force applied to the transmission element via the secondary pulley, and the pinching force applied being determined, at least in part, as a function of a torque which is to be transmitted. The transmission is adapted in such a manner that, at least while the pulleys are at a standstill or during the initial revolutions of the driven pulley, prior to the abovementioned method of control during full movement, the transmission is controlled in a different way which effects the presence of pinching force in the primary pulley.
