    摘要： 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.

    摘要： A continuous variable transmission includes a pair of pulleys forming V-shaped grooves for receiving an endless transmission element for transmitting torque between the pulleys. Each pulley includes at least one axially movable sheave which may be urged axially in the direction of the transmission element by an urging element effecting a clamping force between the sheave and the transmission element, the effected clamping force corresponding to a force sufficient for transmitting a torque to be transmitted by at least virtually slipless friction between the pulley sheaves and the belt, increased by a safety margin expressed as a factor corresponding to a percentage of the torque to be transmitted throughout a major part of the range of torques transmittable to the relevant transmission.

    摘要： Continuously variable transmission provided with a first pulley having two pulley discs, with a second pulley having two pulley discs and with a drive belt wound around the pulleys for transmitting torque therebetween, at least one disc of the first pulley being axially movable with respect to the other disc of the pulley under the influence of an axial force provided on the movable disc by a hydraulic pressure in a cylinder of a piston/cylinder assembly associated with the first pulley. The continuously variable transmission is further provided with a control system capable of controlling the pressure in the cylinder and including a pump for generating a flow of hydraulic medium from a reservoir to a main hydraulic line and a line pressure valve at least operable by a control pressure which is regulated by an electronically operable pressure regulator, for controlling a line pressure in the main hydraulic line. Additionally the control system includes a pressure control device capable of influencing the line pressure by providing a further pressure on a part of the line pressure valve.
