DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing foreign matter from being caught between tires in an industrial vehicle having double tires.

[0002]

2. Description of the Related Art Conventional technology of this kind is disclosed in
No. 7-19147, Japanese Utility Model Laid-Open No. 4-119259, Japanese Utility Model Laid-Open No. 3-64161, Japanese Utility Model Laid-Open No. 2-107555, Japanese Utility Model Application Laid-Open No. 62-88688, and the like are known. However, Japanese Utility Model Application Laid-open No. 57-19147 detects a stone or the like caught between double tires of a road running vehicle and issues a warning to the driver. In addition, 4-
No. 119259 sets a stone discharging arm only when a stone or the like always caught by a wire stretched between double tires is removed. 2-1075
In the case of No. 55, in the case of a double row double tire, a V-shaped belt-shaped removing device is suspended to remove stones and the like while driving by running. In the case of Japanese Utility Model Laid-Open No. 62-88688, A single-row double tire is provided with a V-shaped belt-shaped elimination device.

[0003]

However, in the above-mentioned prior art, the main purpose is to prevent a stone or the like caught between double tires from jumping while driving on a road to prevent danger to a person or a following vehicle. To prevent various miscellaneous foreign substances including stones from being caught in the double tires of work vehicles used at waste disposal sites, etc. during work, damaging the tires and making it easier for the tires to slip Has a problem that the conventional apparatus has insufficient rejection performance.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is intended to prevent various miscellaneous foreign substances including stones from being interposed between double tires. is there. According to the first aspect of the present invention, a plate-shaped member plate having an increased thickness is disposed in a space formed between two wheels of a double tire, and the thickness of the plate is increased to fill the space. At the same time, the plate-like plate has a shape in which the width dimension in the wheel rotation direction is increased to provide strength and rigidity.

[0005] In the space created between the two tires described above,
Large plate thickness and width to occupy a large volume reduce the space for foreign substances to enter, and the configuration in which a plate with high strength and rigidity in the wheel rotation direction is arranged to disperse on the traveling road surface It is difficult for miscellaneous foreign substances to enter or be caught between the double tires while the industrial vehicle is running. Further, when the foreign matter that has been caught hits the plate, the foreign matter is easily removed.

[0006] Therefore, while the industrial vehicle is running, the foreign matter caught between the wheels hits the plate and is pushed out from between the wheels, so that the foreign matter will not be clogged in the space of the double tire, and the foreign matter removal effect will be eliminated. Is remarkable.

According to a second aspect of the present invention, a hard rigid rubber material is used as a material of the plate, so that a foreign object sandwiched between the wheels collides, whereby the plate is deformed and bent to hit the tire. In such a case, unlike a case of an iron plate or the like, consideration is made so as not to damage the tire.

According to the third aspect of the present invention, a plurality of projections are provided on the surface of the plate facing the wheel, so that foreign matter is more difficult to enter between the wheel and the plate.

According to the fourth aspect of the present invention, the brush is provided on the surface of the plate facing the wheel, and the effect of removing foreign substances can be further enhanced.

According to a fifth aspect of the present invention, the brush body is disposed in a space formed between two wheels of the double tire instead of the plate-like plate. In the case where the foreign matter clogging the space of the double tire is in the form of gravel, it can be eliminated by applying a slight impact to the portion where the bridge is formed, so that the device can be simplified.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of an industrial vehicle showing one embodiment of the present invention, FIG. 2 is a side view of a front wheel portion of the industrial vehicle, and FIGS. FIG. 5 and 6
FIGS. 7, 8, and 9 show a first embodiment, a second embodiment, a third embodiment, a fourth embodiment, and a fifth embodiment of a mounting structure of the double tire foreign matter removing device to the fender.

In the industrial vehicle shown in FIGS. 1 and 2, the front wheels are double tires 8 and the steering is performed by the rear wheels. A fender 2 is provided in a space 9 between the two wheels 3 of the double tires 8. Although the plate-like plate 1 is attached from the above, there is no problem in running at all. Therefore, the problem is solved by arranging the plate 1 of the double tire foreign matter removing device and making the plate 1 more removable.

The double tire foreign matter removing device shown in FIG.
In the front explanatory view in which the plate 1 is enlarged and FIG. 4 showing an AA sectional view of FIG. 3, the fender 2 is fixed to the frame 4 of the vehicle body by bolts 5 and is fastened to the fender 2 by another bolt 5. Plate 1 is
The double tire 8 is disposed so as to hang down in a space 9 between the two wheels and occupy the space 9 in the front-rear direction and the left-right direction at the top.

A vehicle running on a public road does not correspond to a foreign matter such as a stone that happens to be caught between the double tires 8. Therefore, since the plate 1 always removes foreign substances from the wheel 3, the plate must be considered as a consumable part. Therefore, there is a demand for a structure of the mounting portion that can be easily replaced.

FIG. 5 shows a first embodiment showing the structure of the mounting portion.
The plate 1 is further fastened with bolts 5 to the fender 2 fastened to the frame 4 of the vehicle body with bolts 5 and has the same structure as the mounting portion shown in FIG.

FIG. 6 shows a second embodiment of the structure of the mounting part in the case of the fender 2 integrated with the frame 4 of the vehicle body. This makes it difficult to attach and detach the camera.

7, 8, and 9, a hole 21 is provided in the fender 2, and the plate 1 and the brush body 6 are inserted into the space 9 (not shown) of the double tire 8 (not shown) from the hole 21. , 6 ′ are hung down and fixed by bolts 5 from the outside of the fender 2 to show the third, fourth and fifth embodiments, respectively. The brush bodies 6 and 6 ′ shown in FIGS. 8 and 9 are examples in which brushes having different flocked states can be used depending on the type of foreign matter.

These double tire foreign matter removing devices are effective when selected in consideration of the foreign matter removing function according to the conditions of the traveling road surface of the industrial vehicle.
