DEVICE FOR PREVENTING HYDRAULIC CLUTCH FROM SHOCK IN FITTING

摘要

PURPOSE:To prevent a hydraulic clutch from shock in fitting by regulating work ing oil pressure automatically on the basis of the signal from an oil pressure detector in fitting the hydraulic clutch. CONSTITUTION:Working oil sucked from an oil pan 1 by a gear pump 2 is introduced from an oil supply path 6 into a pressure regulating valve 6 to be regulated with respect to its pressure, and then introduced into an advancing cylinder 10 or a retreating cylinder 11 of a hydraulic clutch respectively through an advancing change-over valve 8 or a retreating one 9 from an oil supply path 7 after regulating pressure. On a servo valve 17 of a drive device 13 for the pressure regulating valve 6 is mounted a detecting guide pin 20 which moves integrally with the servo valve 17 and the position of which is measured by a potentiometer 21 to form thereby an oil pressure detector 22.
