ABSTRACT:
A control system for a continuously variable sheave drive having a driving sheave assembly (124) and a driven sheave assembly (126) connected drivably by a torque transfer belt or chain (144), each sheave assembly being comprised of a pair of friction drive sheave portions (128/130 and 178/180) that are axially adjustable, one with respect to the other, to establish varying pitch radii, each sheave assembly having a fluid pressure operated servo with a pressure chamber (164/212) supplied with control pressure from a pressure source, distribution of control pressure to one servo assembly effecting a pitch radius adjustment thereby changing the overall drive ratio, control pressure distribution to the other sheave assembly resulting in a clamping force, and valve means for limiting the rate of delivery of pressurized fluid to the ratio controlling sheave assembly (124) so that control pressure will not fall below a desired value.
