Abstract

The disclosure provides a work vehicle in which clogging of a filter of an air cleaner with snow can be suppressed. The work vehicle includes: a radiator that cools cooling water for an engine; an air cleaner that cleans air to be fed to the engine; and an inlet hose that has an aspiration port open on a rear side of the radiator and leads the air from the aspiration port to the air cleaner. The radiator includes a shroud having an opening in which a fan of the engine is disposed and the aspiration port is disposed not to overlap with the opening of the shroud in back view.

Claims (47)

1. A work vehicle comprising:

a radiator that cools cooling water for an engine;

an air cleaner that cleans air to be fed to the engine; and

an inlet hose that has an aspiration port open on a rear side of the radiator in a front-back direction of a vehicle body and leads the air from the aspiration port to the air cleaner,

wherein the radiator includes a shroud having an opening in which a fan driven due to the driving of the engine is disposed, and

wherein the aspiration port is disposed behind the shroud in the front-back direction of the vehicle body.

2. The work vehicle as claimed in claim 1 , wherein

the aspiration port is disposed not to overlap with the opening of the shroud in back view.

3. The work vehicle as claimed in claim 2 , wherein

the aspiration port is disposed at a lower position than a central portion in a vertical direction of the radiator.

4. The work vehicle as claimed in claim 3 , wherein

the aspiration port is disposed in a vicinity of a cooling water hose through which the cooling water flows between the radiator and the engine.

5. The work vehicle as claimed in claim 4 , wherein

the cooling water hose includes a lower hose through which the cooling water flows between a lower portion of the radiator and the engine, and

the aspiration port is disposed in a vicinity of the lower hose.

6. The work vehicle as claimed in claim 5 , wherein

the aspiration port is disposed to overlap with the lower hose in plan view.

7. The work vehicle as claimed in claim 2 , wherein

the aspiration port is disposed in a vicinity of a cooling water hose through which the cooling water flows between the radiator and the engine.

8. The work vehicle as claimed in claim 2 , wherein

the air cleaner is disposed on the rear side of the radiator.

9. The work vehicle as claimed in claim 1 , wherein

the aspiration port is disposed at a lower portion than a central portion in a vertical direction of the radiator.

10. The work vehicle as claimed in claim 9 , wherein

the aspiration port is disposed in a vicinity of a cooling water hose through which the cooling water flows between the radiator and the engine.

11. The work vehicle as claimed in claim 10 , wherein

the cooling water hose includes a lower hose through which the cooling water flows between a lower portion of the radiator and the engine, and

the aspiration port is disposed in a vicinity of the lower hose.

12. The work vehicle as claimed in claim 11 , wherein

the aspiration port is disposed to overlap with the lower hose in plan view.

13. The work vehicle as claimed in claim 1 , wherein

the aspiration port is disposed in a vicinity of a cooling water hose through which the cooling water flows between the radiator and the engine.

14. The work vehicle as claimed in claim 13 , wherein

the cooling water hose includes a lower hose through which the cooling water flows between a lower portion of the radiator and the engine, and

the aspiration port is disposed in a vicinity of the lower hose.

15. The work vehicle as claimed in claim 14 , wherein

the aspiration port is disposed to overlap with the lower hose in plan view.

16. The work vehicle as claimed in claim 14 , wherein

the air cleaner is disposed on the rear side of the radiator.

17. The work vehicle as claimed in claim 13 , wherein

the air cleaner is disposed on the rear side of the radiator.

18. The work vehicle as claimed in claim 1 , wherein

the air cleaner is disposed on the rear side of the radiator.

19. The work vehicle as claimed in claim 1 , wherein

the inlet hose is installed along the radiator from an upper portion to a lower portion of the radiator with an upper end portion connected to the air cleaner and the aspiration port formed in a lower end portion.

20. The work vehicle as claimed in claim 1 , wherein

the air cleaner is disposed on the rear side of the radiator.
