<p><P>PROBLEM TO BE SOLVED: To reduce or prevent shock generated during repeating operation for engaging/disengaging of the same clutch in a predetermined very short time. <P>SOLUTION: In this control method of hydraulic multiple-disc clutch wherein frictional plates are rapidly brought into close to each other just before slip engagement by increasing initial filling pressure of a hydraulic oil, then the pressure of hydraulic oil is reduced from the initial filling pressure by a prescribed pressure to slip and engage the frictional plates with each other, then the pressure of hydraulic oil is increased with prescribed gradient and the clutch is engaged, thus the shock in engaging of the clutch is relieved, the initial filling pressure is lowered by the predetermined pressure only when the same clutch is engaged again within the predetermined very short time from a time when the clutch pressure becomes 0 as a result of disengaging operation of the engaged clutch. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
