<p>The pulley gears has a pair of conical discs (5, 6) on drive and the cone pulleys (3, 4) are connected with shafts (1,2), and a traction mechanism line (9) between the discs. A cylinder-piston assembly is formed by the axially sliding conical discs with piston fixed to the shaft, which adjusts and maintains the gear ratio of a pump (16). The control piston (13) is impinged by pressurized fluid and is connected with a clamping device (28,33), which firmly clamps the piston in a position available in time with a drop in pressure.</p> |
