摘要:
Hydraulic pressure is controlled, which has such advantages that a generation of peak pressure (shoot pressure) can be lowered, mis-operation due to biting of particles can be reduced, or the cost thereof can be reduced. First, a large amount inflow command current is supplied to a proportional solenoid from a time point t1 to a time point t2. Consequentially, pilot pressure rises in a pilot pressure receiving chamber, so that a pressure control valve allows a large amount of hydraulic fluid to flow in a clutch or brake cylinder. At this time, potential detected by a pressure switch becomes zero level. Next, at the time point t2, a filling command small current is supplied to the proportional solenoid, thereby decreasing the amount of hydraulic fluid, which flows from an input port to an output port. This state is maintained from the time point t2 to a time point t3. At the termination of filling, peak pressure will not be generated, and a speed-changing shock in a clutch will not be generated, so that smooth switching can be accomplished.

A brake device lubrication device includes a lubricant supply unit and a control unit. The control unit includes a braking timer, a release timer and a storage unit. The control unit is configured to control the lubricant supply unit so as to supply a predetermined first supply amount of lubricant to a brake device when the brake device is in a braking state, to acquire a delay time corresponding to a braking time counted by the braking timer from a relationship of correspondence between the braking time and the delay time stored by the storage unit when the brake device is switched from the braking state to a released state, and to switch a supply amount of lubricant from the first supply amount to a second supply amount which is smaller than the first supply amount when the release time counted by the release timer reaches the acquired delay time.

A transmission control device includes a load increase rate computation portion and a transmission control portion. The load increase rate computation portion is configured to compute an increase rate of a load acting on the work vehicle. The transmission control portion is configured to shift a high-speed gear down to a low-speed gear with producing a lock-up state in which a lock-up clutch is engaged when the load increase rate is less than a load increase rate threshold in shifting the high-speed gear down to the low-speed gear, and producing a torque converter state in which the lock-up clutch is disengaged when the load increase rate is equal to or greater than the load increase rate threshold in shifting the high-speed gear down to the low-speed gear.

An engine output control system is for a work vehicle composed of an engine, a travel device and a power transmission unit, the power transmission unit including a torque converter and transmitting an output of the engine to the travel device via the torque converter. The engine output control system includes a speed ratio computation portion and an engine output reduction control portion. The speed ratio computation portion is configured and arranged to compute a speed ratio of the torque converter. The engine output reduction control portion is configured and arranged to reduce an output torque of the engine without changing a target speed of the engine when the computed speed ratio is equal to or less than a speed ratio threshold set in advance. The speed ratio threshold is a speed ratio at which a torque ratio of the torque converter is greater than a torque ratio corresponding to a maximum efficiency.
