COOLING STRUCTURE OF HYDRAULIC OIL TANK IN WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To effectively cool hydraulic oil in a hydraulic oil tank.

SOLUTION: A baffle plate 15 which divides the hydraulic oil tank into a feed oil chamber 14 to which a feed pipe 18 for feeding hydraulic oil to hydraulically-driven equipment is connected and a return oil chamber 13 to which a return pipe 17 for returning hydraulic oil from the hydraulically-driven equipment is connected is provided in the hydraulic oil tank 11. A communication part 16 for sending the hydraulic oil from the feed oil chamber 14 to the return oil chamber 13 is formed at an upper part of the baffle plate 15. The baffle plate 15 is provided with a partition wall cooling part 12A which forms a hollow part as an air cooling chamber 21. A return oil chamber cooling part 12B which cools an air cooling air duct 22 for sending cooling air to the air cooling chamber 21 by dipping the air cooling air duct in the hydraulic oil in the feed oil chamber 14 is provided and further a feed oil chamber cooling part 12C which cools an air cooling ventilation duct 23 for discharging cooling air from the air cooling chamber 21 by dipping the air cooling ventilation duct in the hydraulic oil in the return oil chamber 14 is provided.
