    摘要: An invention relating to a control apparatus and a control method for a hydraulically driven cooling fan for reducing the peak pressure produced upon reversing the switch position of a switching valve, without stopping an engine, and without greatly modifying existing hydraulic circuitry or increasing the apparatus cost. In the invention, in the case that a reversing switch has been operated so as to output a reversal processing commencement instruction signal, control is carried out such that, under the condition that the rotational speed of the engine has decreased to not more than a stipulated rotational speed, capacity adjusting means is controlled, so as to reduce the capacity of a hydraulic pump, and thus reduce the fan rotational speed, and then the switch position of the switching valve is reversed.

    摘要: The present invention provides a drive device for a working vehicle whereby gear change shock during the forward/reverse running changeover action can be reduced while achieving shortening of cycle time and protecting various clutch mechanisms in the transmission. If a reverse running command is output from a running control device while the vehicle is running forward, an ECMV controls a braking force of a brake device so as to reduce a vehicle speed through a first prescribed speed to a second prescribed speed, and disengages the forward clutch. When the vehicle speed reaches the first prescribed speed, the ECMV puts the reverse clutch in a slipping action condition and, after the vehicle speed reaches the second prescribed speed, gradually engages the reverse clutch.

    摘要: An engine control apparatus for a work vehicle having a cooling fan or an auxiliary device driven by an engine. The engine control apparatus is capable of operating the work vehicle with the importance placed either on amount of work or fuel economy depending on the situation, and preventing the input of excessive traveling horsepower (or working horsepower), regardless of a selected work mode, to ensure durability of the traveling power train (or work machine drive equipment). Upon selection of a work mode by the work mode selection switch, a controller controls the engine to obtain a power curve selected from those selectable for the selected work mode can be obtained, based on the coolant temperature range and the selected work mode, so that the input torque transmitted to the traveling power train does not surpass the upper limit for the input torque (rated output).
