Hydraulic control system for a belt drive continuously-variable speed transmission

摘要: A hydraulic control system for a belt drive continuously-variable speed transmission comprising means including primary variable-pitch pulley having fixed flange to an input shaft and movable adapted be axially slidable on said shaft, secondary output endless interconnecting pulleys; circuit servomechanisms hydraulically interconnected with the respective flanges of pulleys pressing corresponding toward flanges, regulator valve supplying pressurized working fluid controlled pressure servomechanisms, capable generating signal change fluid. The is incorporated into generate axial movement feed valve, whereby factor speed-change ratio added flowing passages circuit.
