Abstract

PURPOSE: To simplify the piping for passing hydraulic fluid used in a cooling fan driving system, by disposing radiators for cooling the cooling fan driving system in air ducts in which a cooling fan is provided.
CONSTITUTION: When a hydraulic motor 13 is rotated by a hydraulic pump 14 and a cooling fan 12 is set into rotation, external air is introduced into air ducts 11 as shown by arrows in the drawing. Therefore, intake air supplied from intake ducts 17 is cooled by intake radiators 18 which are cooled by the external air introduced into the air ducts 11 as described above, so that the intake air is supplied at a low temperature to the engine via intake ducts 19. On the other hand, hydraulic oil passed through a pipe 16 for driving cooling fan 12 is also cooled when passing through a hydraulic-circuit radiator 20 which is cooled by air introduced duct 11. Since, with such an arrangement, it is made unnecessary to extend the piping for passing hydraulic fluid for driving a cooling fan to the outside of the vehicle body, the hydraulic piping for the cooling fan driving system can be simplified.
