を切ると脱輪の恐れがあった(図5(c))。2. Description of the Related Art A conventional rubber crawler A is formed by simply connecting a core metal 1 embedded therein with a steel cord 2 via rubber (FIG. 1). With this structure, the rigidity was very weak and it was easy to derail. As a countermeasure against this, a steel-made bias cord 3 is added as shown in FIG.
Protrusions 4a and 4b are provided on the front and rear of the core metal 1 as
There is one in which the protrusions of the front and rear core bars 1 and 1 are brought into contact with each other to improve the lateral rigidity. But rubber
No particular measures were taken for the elongation of La-A in the front-back direction. For this reason, when the stone 7 is caught in the front idler 5 (Fig. 5) during traveling, the link floats up from the brim of the front idler 5 (Fig. 5 (b)), and if the steering wheel is cut in that state, there is a risk of wheel removal. (Fig. 5 (c)).

する。As described above, a construction machine such as a hydraulic excavator equipped with a rubber crawler has a drawback in that it is easy to derail the wheels, but one of the factors is insufficient rigidity of the rubber crawler. . An object of the present invention is to increase the rigidity of a rubber crawler and thereby improve the derailing performance.

【課題を解決するための手段】建設機械等に使用される
ゴムクロ−ラにおいて、進行方向前後のゴムクロ−ラの
芯金1に横方向と縦方向の両方向で互に干渉し合う鉤形
突起6a,6bを設けた。[Means for Solving the Problems] In a rubber crawler used for a construction machine or the like, a hook-shaped projection 6a that interferes with the core metal 1 of the rubber crawler before and after the traveling direction in both the lateral direction and the longitudinal direction. , 6b are provided.

とができる。[Operation] The hook-shaped projections 6a and 6b provided on the core metal 1 interfere with each other,
It is possible to prevent this even if there is a tendency to shift in the front-back or left-right direction.

ロ−ラの前後方向に引張られた時に互に接触する鉤状の
突起6a及び6bをこれと一体に設けた。EXAMPLE An explanation will be given with reference to FIG. As shown in FIGS. 1, 2, and 3, the core bar of the conventional rubber crawler A does not have a structure to restrain the tensile load in the front-rear direction of the crawler. Therefore, only the steel cord 2 has a force to suppress the elongation of the rubber crawler A. In this structure, the restraint force against elongation was weak. To solve this problem,
As shown in FIG. 3, the protrusions 4a and 4b of the core metal 1 are provided integrally with hook-shaped protrusions 6a and 6b which come into contact with each other when the core metal 1 is pulled in the front-back direction of the crawler. .
【0007】このように鉤状の突起6a,6bを設けた芯金

伸びに対して芯金1の鉤状突起6a,6b同志が接触するの
で、横方向の剛性が向上すると共に、縦方向の剛性も飛
躍的に向上させることができる。By using the core metal 1 provided with the hook-shaped projections 6a and 6b as described above, the hook-shaped projections 6a and 6b of the core metal 1 come into contact with each other with respect to the elongation of the rubber crawler A in the front-rear direction. Therefore, the rigidity in the horizontal direction can be improved, and the rigidity in the vertical direction can be dramatically improved.

ることができる。[Effect] If the stone 7 (Fig. 5) bites into the front idler 5 during running and the rubber crawler A extends, the height of the brim of the front idler 5 is set larger than the stroke of the recoil spring. However, the link floated from the brim of the front idler 5, and there was a high possibility that the wheel could be derailed if the steering wheel was cut in that state. By using the cored bar 1 of the present invention, it is possible to prevent the link from floating from the brim of the front idler 5, and to further improve the anti-wheel release property against the biting of the stone 7.
