Abstract

PURPOSE: To prevent a clutch from seizure when an engine increases its rotary speed, by performing control operation for oil pressure of the clutch with a solenoid valve, opening the solenoid valve and directly coupling the clutch when the engine exceeds its prescribed rotary speed.
CONSTITUTION: A controller 21 for controlling clutch oil pressure is constituted in such a manner that signals from a pick-up coil 22 for detecting rotary speed of an engine and from a pick-up coil 23 for detecting rotary speed of an output shaft 1 of the engine perform open-close control of a solenoid valve 20 and control the clutch oil pressure. Accordingly when the engine rotary speed increases to exceed a preset rotary speed, the solenoid valve 20 is selected the position 20B to obtain a directly coupling state for a clucth 6 or 7 and prevent the clutch from seizure.
