DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing cooling air once passing through a radiator from being wrapped around a radiator mounted on a vehicle to the front of the radiator.

[0002]

2. Description of the Related Art As shown in FIGS. 6 and 7, in a vehicle such as a cab-over type truck in which side rails 2 having a U-shaped cross section are disposed on both sides of a radiator 1 for cooling engine cooling water. Air drawn into the radiator 1 from the front of the vehicle by a fan (not shown) behind the radiator 1 and heated by cooling of engine cooling water passes through the inside of the U-shape of the side rail 2 and moves forward of the radiator 1 as shown by an arrow. Conventionally, a hard rubber plate 3 is disposed inside a U-shaped side rail 2 on the side of the radiator 1 in order to prevent the radiator 1 from being rewound and sucked into the radiator 1 again to lower the cooling efficiency. By inserting bolts 6 into bolt holes (not shown) formed in the upper flange 4 of the side rail 2 and bolt holes 5 of the rubber plate 3, the rubber plate 3 is removed. Idoreru attached to upper flange 4, had an internal side rail 2 at the side of the radiator 1 so as to close the vehicle width direction.

In this case, it is necessary to cover the inside of the side rail 2 with the rubber plate 3 in order to improve the effect of preventing the cooling air passing through the inside of the side rail 2 from being wrapped around. Since various pipes, harnesses, and the like are arranged, a notch 8 for inserting the pipe or the like into the hole 7 of the rubber plate 3 must be provided.

However, since the notch 8 is provided, the rigidity of the rubber plate 3 is reduced, so that the rubber plate 3 is easily bent.
If the rubber plate 3 is made thicker to increase its rigidity, it becomes difficult not only to insert the pipe or the like into the notch 8 of the rubber plate 3 but also to increase the weight of the rubber plate 3 and to make it difficult to mount the rubber plate 3. It led to a problem.

In order to mount the rubber plate 3 inside the side rail 2, it is necessary to make a bolt hole in the upper flange 4 of the side rail 2, and furthermore, when the radiator 1 is mounted, it comes into contact with the side wall 9 of the radiator 1. There is a possibility that the side edge of the rubber plate 3 may be turned up or a crack may be generated on the side edge.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to prevent cooling air from flowing back through a side rail inside a radiator of a vehicle and to arrange pipes and the like in the side rail without any trouble. To be able to do it.

[0007]

SUMMARY OF THE INVENTION Therefore, a radiator anti-rollback device according to the present invention comprises a side rail having a U-shaped cross section extending substantially in the front-rear direction of a vehicle, and a side rail on a side of a radiator mounted on the vehicle. A sponge rubber plate provided inside the rail and closing the inside of the side rail in the front-rear direction of the vehicle , and the side
It has a stay attached to the rail, and the plate is
A pipe or the like, which is attached to the stay and is formed inside the side rail, penetrates a space formed in the plate.

[0008]

[Function] That is, the inside of the side rail on the side of the radiator is attached to the stay attached to the side rail.
The plate is closed in the front-rear direction of the vehicle, but this plate is made of sponge rubber and has relatively high elasticity, so that even if the plate is thick, a pipe or the like can be easily inserted into the space. Therefore, the relatively thick plate can reliably prevent the cooling air that has once passed through the radiator from being wrapped forward from the inside of the side rail.
