より大きく浮き上ってしまい脱輪を生ずる結果となる。A conventional rubber crawler 100 of this kind is, as shown in FIG. It is configured to move around the inner surface of the crawler 100. Rubber crawler 1 used for small vehicles
00 has one sprocket drive hole in the direction perpendicular to its longitudinal direction, that is, in the width direction, but the rubber crawler 100 used for large vehicles has a drive hole in the sprocket 1 in the width direction. It is also known that two such devices are provided in parallel. As shown in FIG. 2, such a large rubber crawler 100 has two core metals 101 buried in the width direction. These core metals 101, protrusions 102 of 101,
102 is made as high as possible to prevent the wheels 3 and 3' from coming off, but due to the manufacture of the core metal, the height of the protrusion cannot be increased indefinitely, and the maximum height is about 45 mm. Moreover, since the wheels 3 and 3- move independently, twisting occurs in the rubber crawler 100, and the protrusions 102 and 10
Wheels 3 and 3, which were caught between the two, often fell off. In addition, these core metals 101, 101 are provided in pairs in the width direction, and since the rolling wheels 3, 3' run on the respective core metals 101, 101, as shown in FIG. When one side of the rubber crawler 100 in the width direction rides on a stone block or the like, one of the wheels 3' rises above the space between the protrusions 102, causing the wheel to come off.

けたものにおいて効果が大きい。As explained above, according to the present invention, a large number of core metals are embedded parallel to each other at right angles to the longitudinal direction of the crawler body molded from rubber, and a tensile force that surrounds the outer peripheral side of the core metal is embedded. A rubber crawler with a reinforcing member embedded in the rubber has a large protrusion located at the widthwise center of the crawler body, and sprocket drive holes are provided in the rubber between the cores on both sides of this large protrusion. , the core metal can be buried in the width direction of the crawler body as one piece, which improves the torsional rigidity of the crawler body, and minimizes deformation even when the crawler body is twisted by riding on a stone block etc. Damage can be prevented. Furthermore, due to the improved torsional rigidity and the presence of large protrusions, it is possible to prevent the rolling wheels from coming off. Furthermore, since there is only one core protrusion, processing becomes easier, and the height of the protrusion can be almost doubled, which was impossible with the conventional two protrusions. Furthermore, although the tensile reinforcing members were conventionally buried separately on the left and right sides, in the present invention, they only need to be embedded in one row to the required width in the center of the crawler body, making molding extremely easy. Furthermore, the mold setting time required for embedding the metal core in the crawler body is reduced to one-half of the time required for conventional two-row metal-core bridge construction, and the number of man-hours can also be reduced. Furthermore, since the sprocket drive holes are on the left and right sides, the driving force of the sprocket wheel is applied evenly to the left and right sides of the crawler body, which prevents overloading the crawler body and ensures that the crawler body is always horizontal at the sprocket wheel and touches the ground. This provides excellent stability, and the presence of holes for driving the left and right sprockets reduces the total weight of the rubber crawler. Particularly, weight reduction is particularly effective when the core metal is divided into left and right sides.
