<p>PURPOSE:To realize clutch control with high precision by changing oil pressure force itself which drives the clutch and adjusting torque transmitted from a driving gear to a driven gear. CONSTITUTION:A branch pipe 40 branching off from an ejection duct 33 communicates with the port 2a of a pressure control valve M. A dust 41 branching off likewise from the ejection duct 33 communicates with a port 3b through an orifice 6. Further, pressurized oil ejected from drain ports 2b, 4a of the pressure control valve M is sent out into a liquid tank 32. Therefore, oil pressure force of pressurized oil sent into a clutch 39 is controlled on the basis of oil pressure force P of branching pressurized oil from the branch pipe 40 after being controlled by the pressure control valve M. Thus, clutch control with high precision can be performed.</p> |
