<p>PURPOSE:To reduce a slip ratio by providing a control device which makes a clutch engaging pressure full pressure when a power take-out shaft is in a rotating condition and which makes the engaging pressure full pressure by rotation after keeping the rotation under a pressure reduced condition for a certain time at the time of a stopped condition, on a power take-out clutch. CONSTITUTION:In a clutch control device 3, when a power take-out switch 29 is turned on and as the rotation of a power take-out shaft 1 is detected by a rotation sensor 28, a pressure control valve 27 is switched over to output the clutch engaging pressure of a power take-out clutch 2 under full pressure immediately engaging the clutch 2. When it is detected that the power take-out shaft 1 is already in a rotation stopping condition, the clutch 2 is engaged under a clutch engaging pressure which is lower than the full pressure and, at this time, as the power take-out shaft 1 is rotated, after keeping the rotation for a certain time, the clutch engaging pressure is made full pressure to engage the clutch 2. Hence, the control of clutch engagement can be accurately carried out, further enabling efficient power transmission with less clutch slippage.</p> |
