<p>A continuously variable transmission provided with a primary pulley (2, 3) mounted on a primary (1) shaft and a secondary pulley (8, 9) mounted on a secondary shaft (7). A transmission means (14) is passed over said pulleys (2, 3, 8, 9). Both the primary pulley (2, 3) and the secondary pulley (8, 9) comprise a pair of discs. At least one of said discs is axially movable by means of a hydraulic cylinder (4, 11), so as to adjust the position of the transmission means around the pulleys and thus the transmission ratio of the transmission means. The pump (20) for providing fluid to said hydraulic cylinders (4, 11) has a variable delivery, so as to enhance the transmission efficiency. <IMAGE></p> |
