のための耐久性がない。(1) Segment tires basically have poor heat balance. Even if the elastic segment 4 is provided with the through-hole 5, for example, it generates heat and emits smoke during continuous running at a speed of 30 to 50 km / h, for example. That is, there is no durability for high-speed continuous running.

a. For this reason, even if the bolt 7a is screwed onto the nut 7b, the elasticity of the base 4a acts, and it is difficult to securely fix the elastic segment 4 to the rim 3b. Therefore, a large number of bolts 7a and nuts 7b are used to eliminate the influence of the elasticity of the base 4a. That is, the structure becomes complicated, and the work of attaching and detaching the elastic segment 4 from the rim 3b is troublesome.

Since the head and the fixing plate 6 are embedded, the structure becomes complicated. Therefore, the manufacturing process becomes complicated and uneconomical. Furthermore, in the case of simple damage such as breakage of the bolt 7a or crushing of the thread, the elastic segment 4 itself must be replaced and cannot be easily repaired, which is uneconomical.

Therefore, the heat balance is improved, which contributes to achieving high-speed continuous running. The elastic segment is completely fixed to the wheel ring by bolting the steel bar and the first flange. Therefore, unlike the related art, a large number of bolts and nuts are not required. That is, the structure becomes simple, and the work of attaching and detaching the elastic segment from the wheel ring becomes easy.
Further, since the steel rod is merely inserted through the through hole, the elastic segment itself has a simple structure. That is, the manufacturing process of the elastic segment is also simplified. In addition, since the steel rod corresponds to the protrusion in the prior art, the head of the elastic segment is distorted during self-propelling, providing a comfortable ride and steering, and during work, the head is further distorted and may hit the steel rod. Since it comes into contact with the vehicle, vertical movement of the vehicle is eliminated, and high working efficiency can be maintained. That is, according to the first configuration, the segment tire can be continuously driven at high speed regardless of the vehicle, has a good ride comfort and steering characteristics, has a simple structure, and is easily repaired.

In the first segment tire, a steel rod long in the left-right direction is provided in the through hole, and first outward flanges are provided on left and right ends of the outer periphery of the wheel ring, respectively, and the left and right ends of the steel rod are used as the first flange. Bolt tightened. Therefore, it is necessary to increase the strength of the first flange. In such a case, having the second flange has a remarkable effect on improving the strength of the first flange and the wheel ring itself. However, if such a second flange is provided without a break, mud is deposited on the inner surface of the inner surface (especially at the rising corner of the second flange) to cause corrosion, which may cause an unexpected accident in long-term operation. . That is, the cuts promote natural discharge of mud and rainwater.

る。According to the fifth embodiment, the following operation and effect can be obtained. That is, the tire is driven based on the driving force,
Driving wheels that transmit driving force to the road surface and cause slippage generate more heat than driven wheels that do not slip and generate slippage. By the way, the segment tire basically has a poor heat balance as described above. Therefore the fifth
In this embodiment, the driven wheels 21F that generate less heat are used as the segment tires of the first to fourth embodiments, and the driven wheels 2 that generate more heat are used.
1R is provided with a normal tire (strictly, a tire other than a segment tire) into which air pressure is injected, for example. That is, since the driven wheels that generate less heat are the segment tires of the first to fourth embodiments, high-speed continuous running is possible.
Note that this operation and effect is achieved by the driven wheel 21F in the fifth embodiment.
Even if the segment tires of the above-described first to fourth embodiments are conventional segment tires, the effect of being able to withstand high-speed continuous running is the same, although the degree of difference is the same.
