Figure 12 (al) shows a conventional crawler 1 in which the wheels are passed between tires in this way, and includes an endless main body 5, a core bar 6 buried in the main body 5, and an IIP installed in the longitudinal direction of the main body 5. The main body 5 is entirely made of an elastic material such as rubber, and has a "U" shape with both widthwise ends 5a, 5a standing upward. The main body 5 is laid over the tire surface so that the tire 4 comes into contact with the inner peripheral surface of the main body 5.The core metal 6 is embedded at a predetermined pitch in the longitudinal direction of the main body 5. This core metal 6 reinforces the main body 5 with its rigidity.
It extends continuously in the width direction, and both ends thereof are bent upward like both ends 5a, 5a of the main body 5. As shown in FIG.
The vehicle runs on the road surface by shifting the tires between the four, but because the contact area with the road surface is wide, it is possible to drive on uneven roads such as uneven roads or soft roads.

However, in conventional crawlers, when the crawler turns in a straight line by turning the steering wheel, the wheels frequently come off the tires during the turn. (in Fig. 12) shows the turning state of the tire 4. The tire 4 turns (ψ) in the turning direction (rightward +i+1), and the -ζ crawler is pressed in the turning direction by this 1 turn.By the way, the crawler 1 Since a core metal 6 that is continuous in the width direction of the main body 5 is embedded in the main body 5, this core metal 6
Due to its rigidity, the main body does not bend. Therefore, since the entire crawler l maintains the same shape, the side opposite to the turning direction is raised, and the contact area with the road surface is rapidly reduced. As a result, the crawler 1 slips in the direction shown from the solid line to the broken line in FIG. The crawler 1 rides on the upright portion 5a of the tire 4, causing deformation of the tire 4, and the crawler 1 stretches in the width direction due to the load of the tire running on the tire.These factors combine to cause the crawler to derail from the tire 4. Such derailment occurs when the turning angle is The thicker it is, the more likely it is to occur, and for this reason, there is a limit to the turning performance of conventional crawlers.

In addition, the core bar divided into left and right parts makes it difficult for the effects of stress, deformation, etc. in one direction to be transmitted to the other. In this situation, even if the pressure force applied to the tire due to turning is applied, the pressure force only acts on the side of the turn and has little effect on the side opposite to the turn, and the side opposite to the turn maintains its tracking with the tire. For,
This prevents wheels from coming off.

The main body 11 is wound around the tire with its inner peripheral surface in contact with the tire, and is formed to have a width that covers the tread of the tire so that the driving force for running is transmitted. It has become. Further, upright portions 15.15 are formed at both ends of the main body 11 in the width direction to bend upward. This standing portion 15.
15 are formed at a predetermined pitch in the longitudinal direction of the main body 11, and abut on both ends of the tire connected to the tread so as to sandwich from both sides to prevent the main body 11 from shifting in the lateral direction.

The left and right divided bodies 21.21 are molded in the same shape,
The core metal 20 is constructed by arranging the divided bodies 21 and 21 in opposite directions and facing each other on the same line. Each divided body 21 is formed by connecting a horizontal portion 22 extending in the width direction of the main body 11 and a shield portion 23 bent upward from the horizontal portion 22. In this case, the sigilder portion 23 extends within the upright portion 15 of the main body 11 and reinforces the upright portion 15. Further, the distal end portion of the horizontal portion 22 is cut out in an inclined shape, and the left and right divided bodies 21 are arranged to face each other so that the notched surfaces 24 at the distal end portions overlap in a parallel state. By arranging the left and right divided bodies 21 in a ramped manner in this manner, it is possible to impart a predetermined strength to the main body 11 even if the core bar 20 is divided. Since the core metal 20 is divided into left and right parts, the main body 11 has flexibility to bend appropriately at the divided parts,
This makes it possible to prevent wheels from coming off when turning, as will be described later. The reinforcing cord 13 is embedded in the longitudinal direction of the main body 11 so as to be located below the core bar 20 to prevent the main body 11 from elongating.

FIG. 5 shows a turning state in which the crawler 10 of this embodiment is mounted, and the tires 4 are tilted in the turning direction (to the right) due to steering. Due to this inclination, the tire 4 presses the upright portion 15 of the main body 11 located on the turning side (right side). Since the main body 11 is given strength by the core metal 20 provided inside, it can resist this pressing force. In this state, the core metal 20 is divided into left and right parts, and the right-hand divided body 21 receives the pressing force of the tire 4, but this pressing force is difficult to be transmitted to the left-hand divided body 21. Furthermore, the main body 11 has appropriate flexibility due to the division of the core metal 20. As a result, when the pressing force of the tire 4 acts on the right side, the right half of the main body 11 bends to maintain contact with the road surface, so it is possible to secure a contact area with the road surface. It has the ability to follow the tires 4 and can prevent the wheels from coming off the tires 4.

Figure 6 is a characteristic diagram plotting changes in the ground contact area of the crawler against the load from the tires during turning.
Characteristic curve A represents this embodiment in which the core metal is divided;
1 shows a conventional example in which the core metal is continuous. Compared to the conventional example, this example has a smaller variation in ground contact area and is less likely to come off the wheel. In addition, since the core metal is split and the main body is flexible, even if the tire rides on the crawler, the crawler's elongation in the axial direction is reduced, making it even more difficult for the tire to derail. There is. FIG. 7 shows the measurement of the tension of the crawler against the load that causes the tire to run off, and the characteristic curve A shows this embodiment, and the characteristic curve B shows the conventional example. The amount of elongation of the crawler is proportional to its tension, and since the tension of this example is smaller as shown in the characteristic curve kIAA, it can be seen that the amount of elongation of the crawler of this example is smaller. It can be seen that it is difficult for the wheels to come off under heavy loads. Therefore, by dividing the core metal as described above, wheel derailment is less likely to occur and turning performance can be improved. In addition, the weight of the core metal is reduced, making it possible to reduce the weight of the crawler as a whole, thereby improving the ease of handling.
