摘要： A continuously variable belt and sheave drive mechanism for use with an internal combustion engine in an automotive vehicle driveline including a simplified valve system that responds to control commands from a microprocessor that receives input data from engine, turbine and output shaft speed sensors, an engine throttle position sensor and a sheave position sensor as well as other driveline variables so that the operating characteristics of the transmission are matched to the speed torque characteristics of the engine to produce improved driveline efficiency and performance while permitting the engine speed to be related functionally to the throttle position as well as vehicle speed and permitting engine speed to increase when rapid acceleration is desired while minimizing changes in engine speed for small throttle position variations.

摘要： 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.
