Description

[Detailed Description of the Invention] The present invention relates to an improvement of a vehicle body, particularly for an industrial vehicle such as a forklift truck.

For example, in a forklift truck, as shown in FIG.
A weight 4 is attached to the rear end of the side frame 1, and a radiator 5 for cooling the engine 3 is installed between the engine 3 and the weight 4. The radiator 5 is fixed to a bracket protruding from the side frame 1, and the upper part of the weight 4 is also attached to the side frame 1. The engine hood 7 was secured to a protruding bracket, and the engine hood 7 was attached to the upper surface of the weight 4 via a hinge 8.

A cooling fan 9 rotates when the engine 3 operates.
The air pushed backwards by the action of the radiator 5
When passing through the cooling water, it absorbs heat from the cooling water and becomes hot air, which is then discharged to the outside of the vehicle body through the air exhaust opening 6. Because there is a gap, the air that once passed through the radiator 5 and became high temperature bypasses the upper and lower or left and right outer circumferences of the radiator 5 and is guided to the radiator 5 again by the blowing action of the cooling fan 9. occurs, and in this case, the cooling efficiency is significantly reduced and the temperature inside the engine room 2 increases, resulting in a high temperature of the engine hood 7 and the driver's seat, which is usually installed on the top surface of the engine hood 7. So,
This caused discomfort to the driver.

Furthermore, in the above-mentioned case, the installation of the weight 4 or the engine hood 7 requires time and effort to assemble and disassemble, which is disadvantageous in terms of cost.

In view of the above drawbacks, the present invention improves engine cooling efficiency by fixing a sealing frame to the rear end of the side frame to close off the rear part of the engine room, and using the sealing frame to attach various parts. At the same time, the aim was to provide a body for an industrial vehicle that can contribute to cost reduction.

The present invention will be described in detail below based on the illustrated embodiments.

In Fig. 2 and Fig. 3, 1 is the 1 provided on the left and right.
They are a pair of side frames and are connected to each other by a cross member (not shown) or the like.

An engine 3 is disposed within an engine room 2 surrounded by the side frame 1.

A sealing frame 10 is attached to the rear end of the side frame 1.
are integrally fixed by welding etc., and the engine room 2
The rear of the vehicle is shielded from the outside world.

In the sealing frame 10 at a position opposite to the cooling fan 9, that is, at a position opposite to the front end of the air exhaust opening 6 formed in the weight 4, there is an air exhaust through hole 11 of approximately the same size as the radiator 5. is drilled therein, and the ventilation through hole 11 is closed by the radiator 5 which is attached to the sealing frame 10 with bolts or the like.

A weight 4 is moored at the upper part of a bracket 12 protruding from the rear side of the ceiling frame 10, and other parts are fixed to the ceiling frame 10 or the side frame 1 with bolts or the like.

An engine hood 7 is attached to the upper surface of the ceiling frame 10 via a hinge 8.

Although a driver's seat is normally installed on the upper surface of the engine hood 7, the driver's seat, a control device, and cargo handling devices such as a mast are omitted in these drawings.

During operation of the forklift truck configured as described above, relatively low-temperature outside air introduced from the front, side, or bottom of the engine room 2 is sent to the rear by the blowing action of the cooling fan 9 that rotates due to the operation of the engine 3. The air, which has become hot due to the cooling effect when passing through the radiator 5, passes through the exhaust opening 6 of the weight 4 and is discharged to the rear outside the vehicle body.

At this time, during operation, the rear part of the engine room 2 is shielded from the outside world except for the ventilation section of the radiator 5 through which air flows in only one direction due to the blowing action of the cooling fan 9, so the hot air that has passed through the radiator 5 A circulating flow in which the radiator is guided back to the radiator 5 does not occur.

Further, the weight 4, the engine hood 7, and the radiator 5 can be fixed to and separated from the ceiling frame 10 independently of each other.

As described above, according to the present invention, hot air that has just passed through the radiator does not pass through the radiator again, and only relatively low-temperature outside air can be guided to the radiator at all times.
The cooling efficiency is improved, which prevents the engine from overheating, and also suppresses the rise in temperature in the engine compartment, which prevents the engine hood from becoming too hot, which in turn contributes to improving the driving environment. Since weights, engine hoods, radiators, etc. can be attached and detached independently, assembly and disassembly costs can be reduced, and the sealing frame itself acts as a cross member connecting the left and right side frames, making it easier to use. This has the effect of providing a strong car body structure, which can greatly contribute to reducing manufacturing costs, and also has various remarkable effects such as suppressing the dispersion of noise in the engine compartment to the rear of the car body. are doing.

In this application, an embodiment related to a forklift truck has been described, but it is of course applicable to general industrial vehicles including a wide range of agricultural vehicles, construction vehicles, and the like.
