    • A control system for a 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 the pulley (1) under the influence of an axial force provided on the movable disc (7) by a line pressure (PLP) in a cylinder (11) of a piston/cylinder assembly (11, 13) associated with the the first pulley (1) and at least one disc (6) of the second pulley (2) being axially movable with respect to the other disc (8) of the pulley (2) under the influence of an axial force provided on the movable disc (8) by a second cylinder pressure (P2CP) in a cylinder (12) of a piston/cylinder assembly (12, 14) associated with the the second pulley (2). The control system is arranged to control the second cylinder pressure (P2CP) between two pressure levels (PLP; PR) by a second valve (32) that may be influenced not only by a control pressure (PC), but also by the second cylinder pressure (P2CP).
    • 一种用于无级变速器的控制系统,其具有带有两个滑轮盘(5,7)的第一滑轮(1),具有两个滑轮盘(6,8)和带有传动带(10)的第二滑轮(2) 缠绕在所述滑轮(1,2)周围,用于在其之间传递扭矩,所述第一滑轮(1)的至少一个盘(7)在所述影响下相对于所述滑轮(1)的另一个盘(5)可轴向移动 通过与第一滑轮(1)相关联的活塞/气缸组件(11,13)的气缸(11)中的管路压力(PLP)提供在可动盘(7)上的轴向力的至少一个盘 所述第二滑轮(2)的所述第二气缸(6)在第二气缸压力(P2CP)的作用下,在设置在所述可动盘(8)上的轴向力的作用下相对于所述滑轮(2)的另一个盘(8) )在与第二滑轮(2)相关联的活塞/气缸组件(12,14)的气缸(12)中。 控制系统被布置成通过不仅受控制压力(PC)影响的第二阀(32)来控制两个压力水平(PLP; PR)之间的第二气缸压力(P2CP),而且还可以由第二气缸 压力(P2CP)。
