In a continuously-variable-ratio-device ('variator') of the type having races (12, 14, 26, 102) between which drive is transferred by rollers (28) which are movable in accordance with changes of variator ratio, it is necessary to apply a traction load urging the rollers and races into engagement. Each rollers is also subject to a transverse reaction force by a hydraulic reaction roller actuator (32) receiving a i controlled reaction pressure. It is desirable to create a relationship between traction and reaction force, and also to provide for adjustment of this relationship. In the present invention this is achieved hydraulically. A traction pressure related to the reaction pressure is applied to an actuator (72, 100) which creates the traction load. The hydraulics also include a working chaniber (C2, C4, CH1, CH2, CH3) which is selectively connectable to and disconnectable from either (or both) of (i) the reaction pressure and (ii) the traction pressure, the traction force being dependent upon pressure in the working chamber. |
