Abstract

An industrial loader includes a fan and radiator assembly mounted above the engine thereof. The assembly comprises a housing mounted on the loader main frame. A pair of radiator cores are located in opposite sides of the housing. A pair of fore-and-aft aligned, hydraulically driven fans are mounted in the housing and operate to draw cooling air in through the cores and discharge it vertically through the top of the housing.

Claims

1. In a vehicle including a main frame comprising a pair of fore-and-aft extending, transversely spaced frame members and an internal combustion engine positioned between and supported by the pair of frame members, a cooling system for the internal combustion engine, comprising:

a housing releasably secured to the pair of frame members exclusive of and in overlying relationship to the engine;

said housing including top, bottom and opposite end walls cooperating to define generally rectangular openings in opposite sides thereof;

outlet opening means located in said top wall;

engine cooling coil means located in said rectangular openings and mounted to said housing; and

fan means located in an mounted to the housing for drawing air in through the cooling coil means and exhausting it through the outlet opening means.

2. The vehicle as defined in claim 1 wherein said fan means comprises first and second, fore-and-aft aligned fans;

said fans each including a blade and a drive shaft coupled to the blade;

a hydraulic motor coupled to a drive shaft of the first fan and drive transfer means coupling the drive shaft of the first fan to the drive shaft of the second fan and coolant temperature control means for modulating the speed of the motor in accordance with coolant temperature.

3. The vehicle defined in claim 1 wherein said housing is in the form of a rectangular box having four upright corners;

four support legs having upper portions respectively forming said upright corners and having lower ends secured to said transversely spaced frame members.

4. The vehicle defined in claim 2 wherein said drive transfer means comprises a pulley mounted on each of said shafts and a belt received about the pulleys;

an idler pulley arm being mounted for pivotal movement toward and away from the belt;

an idler pulley mounted on the arm and engaged with the belt; and

a biasing means acting on the arm to maintain the idler pulley in engagement with the belt.

5. An engine cooling fan and radiator assembly adapted for mounting above an internal combustion engine to be cooled comprising:

a bottom support wall formed for being mounted in close spaced relationship to the top of an engine;

a pair of end walls respectively joined to and projecting upwardly from opposite ends of the bottom wall;

said bottom wall having generally horizontal rectangular mounting portions along opposite sides thereof;

a pair of generally rectangular, upright frames defining respective rectangular openings and having lower frame members respectively engaged with and releasably secured to said generally horizontal rectangular mounting portions;

a top wall extending between and being releasably secured to respective upper frame members of the frames;

a pair of circular air outlet openings located in said top wall;

a pair of radiators respectively mounted to said pair of frames and located within said rectangular openings; and

a pair of fans mounted to the bottom wall and having respective blades located beneath said outlet openings.

6. The cooling fan and radiator assembly defined in claim 5 and further including four support posts respectively joined to opposite edges of and extending below said end walls.
