とを特徴とするフアン駆動装置。 A hydraulic pump driven by a transmission via a pump clutch, an accumulator in which oil is stored by the hydraulic pump, a hydraulic motor connected to the accumulator via piping, and a switch that switches the accumulator from the hydraulic pump to the hydraulic motor when turned on. A valve and a fan driven by an engine or a hydraulic motor via a fan clutch or a motor clutch are provided, and a pump clutch is connected during braking to accumulate oil in an accumulator,
When the cooling water temperature is higher than a predetermined upper limit, the motor clutch is connected and the switching valve is turned on to drive the fan by the hydraulic motor. At that time, when the oil pressure of the accumulator is lower than the predetermined lower limit, the motor clutch is switched and the switching valve is turned on. At the same time, the fan clutch is connected and the fan is driven by the engine, and when the cooling water temperature is lower than the specified upper limit, the motor clutch is switched and the switching valve is turned OFF.
What is claimed is: 1. A fan drive device comprising: a control device for controlling the fan so that the fan is not driven by disengaging the fan clutch and disengaging the fan.
