Abstract

A dump truck includes: a vehicle body frame extending in a travel direction; cooled objects in a form of an engine and an aftercooler; a first radiator and a second radiator configured to exchange heat between a cooling air and a cooling water after cooling the engine and the aftercooler, in which the first radiator is disposed to an outside of a first of the vehicle body frame in a vehicle width direction and the second radiator is disposed to an outside of a second side of the vehicle body frame in the vehicle width direction.

First claim

The invention claimed is:

1. A dump truck comprising:
a vehicle body frame extending in a travel direction; and
at least a pair of radiators configured to exchange heat between a cooling air and a cooling water after cooling a to-be-cooled object, wherein
a first one of the pair of radiators projects laterally outward relative to a first side of the vehicle body frame in a vehicle width direction, and
a second one of the pair of radiators projects laterally outward relative to a second side of the vehicle body frame in the vehicle width direction.

2. The dump truck according to claim 1 , wherein
the pair of radiators are disposed substantially in a middle of the vehicle body frame in the travel direction.

3. The dump truck according to claim 1 , further comprising:
tires provided to a first side and a second side of the vehicle body frame in the travel direction and both the first and second sides of the vehicle body frame in the vehicle width direction, wherein
the pair of radiators are disposed between the tires provided to the first and second sides of the vehicle body frame in the travel directions.

4. The dump truck according to claim 1 , further comprising:
an engine mounted on the vehicle body frame, and
a water-cooling type aftercooler configured to cool a charge air to be fed to the engine, wherein
the first one of the pair of radiators is configured to exchange heat between the cooling air and the cooling water after cooling the engine, and
the second one of the pair of radiators is configured to exchange heat between the cooling air and the cooling water after cooling the aftercooler.

5. A dump truck comprising:
a vehicle body frame extending in a travel direction;
an engine mounted on the vehicle body frame;
a water-cooling type aftercooler configured to cool a charge air to be fed to the engine;
a first radiator configured to exchange heat between the cooling air and the cooling water after cooling the engine;
a second radiator configured to exchange heat between the cooling air and the cooling water after cooling the aftercooler; and
tires provided to a first side and a second side of the vehicle body frame in the travel direction and a first side and a second side thereof in a vehicle width direction, wherein
the first radiator projects laterally outward relative to the first side of the vehicle body frame in the vehicle width direction,
the second radiator projects laterally outward relative to the second side of the vehicle body frame in the vehicle width direction,
the first and second radiators are disposed substantially in a middle of the vehicle body frame in the travel direction and between the tires provided to the first and second sides of the vehicle body frame in the travel direction, and
sucking type cooling fans configured to suck an outer air inward as the cooling air from an outside of the vehicle body frame are respectively disposed to a side of the first radiator near the vehicle body frame and to a side of the second radiator near the vehicle body frame.

6. The dump truck according to claim 1 , further comprising:
tires;
electric motors configured to drive the tires; and
a pair of brake resistors configured to convert kinetic energy of the tires to electric energy based on the tires being braked,
wherein the pair of brake resistors are disposed at either one of the pair of radiators.

7. The dump truck according to claim 3 , wherein the first one of the pair of radiators is disposed in a first area defined between the tires along the travel direction on the first side of the vehicle body frame, and the second one of the pair of radiators is disposed in a second area formed between the tires along the travel direction on the second side of the vehicle body frame.

8. The dump truck according to claim 1 , wherein the entire portion of the first one of the pair of radiators is positioned outside of the vehicle body frame in the vehicle width direction, and the entire portion of the second one of the pair of radiators is positioned outside of the vehicle body frame in the vehicle width direction.

9. The dump truck according to claim 5 , wherein the entire portion of the first one of the pair of radiators is positioned outside of the vehicle body frame in the vehicle width direction, and the entire portion of the second one of the pair of radiators is positioned outside of the vehicle body frame in the vehicle width direction.
