    摘要： Controlling device for the transmission ratio of an infinitely variable transmission of a motor vehicle, whereby the transmission ratio is adjustable dependent on the position of a hydraulic control valve (20), which is movable under the influence of the difference between a desired and an actual engine speed and means (60, 61, 62) are present for regulating the minimum possible engine speed in dependence of the trans­mission ratio.

    摘要： Continuously variable transmission provided with a first pulley (1) having two pulley discs (5, 7), with a second pulley (2) having two pulley discs (6, 8) and with a drive belt (10) wound around said pulleys (1, 2) for transmitting torque there between, at least one disc (7) of the first pulley (1) being axially movable with respect to the other disc (5) of said pulley (1) under the influence of an axial force provided on said movable disc (7) by a hydraulic pressure in a cylinder (11) of a piston/cylinder assembly (11, 13) associated with said first pulley (1). The continuously variable transmission is further provided with a control system capable of controlling the pressure in said cylinder (11) and comprising a pump (17) for generating a flow of hydraulic medium from a reservoir (34) to a main hydraulic line (15) and a line pressure valve (18) at least operable by a control pressure (P CP ) which is regulated by an electronically operable pressure regulator (29), for controlling a line pressure (P LP ) in said main hydraulic line (15). Additionally the control system comprises a pressure control means (40; 41; 42) capable of influencing the line pressure (P LP ) by providing a further pressure (P FP ) on a part (20) of the line pressure valve (18).
