Abstract

PROBLEM TO BE SOLVED: To reduce vibration and noise, and to sharply reduce a side slip by lateral directional traction by providing the forward projecting part and the backward projecting part in a zigzag shape, and installing them on the outer peripheral surface of a wheel by incorporating the forward/backward projecting parts in the outer peripheral direction of the wheel. SOLUTION: This segment tire 10 is installed on a wheel by successively combining Z shapes having the forward projecting part 1b and the backward projecting part 1c. A bolt 3 welded to core metal 2 is offered for installation with the wheel. Since the crown part in the forward/backward projecting parts 1b, 1c of the segment tire 10 always contacts with the traveling surface when a wheel rotates in the arrow direction, generation of vibration and noise is extremely reduced. While, when force is applied in the lateral direction of the wheel since the side parts 1e of the forward/backward projecting parts 1b, 1c are opposed at a right angle to this force traction is large, so that the occurrence of a side slip as the wheel is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a segment tire to be mounted on a wheel, and more particularly to a segment tire having easy mounting and improved vibration.

[0002]

2. Description of the Related Art In recent years, a technique has been developed in which a segment tire is sequentially mounted on the outer peripheral surface of a wheel to form a wheel. This segment tire has a rectangular shape or V
However, in the former case, the segment tires mounted on the wheels are separated from each other on the running surface when they are used as wheels because their crowns are separated from each other. Occurrence of vibration and noise is inevitably avoided because of the contact. On the other hand, in the case of the latter V-shaped segment tire, it is easy to mount on the outer peripheral surface of the wheel and the vibration is improved, but the traction in the lateral direction is not obtained much, and the wheel is easy to skid. turn into.

[0003]

SUMMARY OF THE INVENTION The present invention provides a segment tire mounted on the outer peripheral surface of a wheel, which reduces vibration and noise and has a large lateral traction.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and the gist of the present invention is a segment tire which is sequentially mounted on the outer peripheral surface of a wheel to constitute a wheel. The protruding part and the protruding part are provided in a staggered shape, and the protruding part and the protruding part of the adjacent segment tires in the outer peripheral direction of the wheel are incorporated into the wheel. The segment tire mounted on the outer peripheral surface of the tire.

[0005] The specific shape of the segment tire is such that the segment tire has a Z shape in plan view. Preferably, one or two of the segment tires are formed at the bottom of the segment tire to reach the portions projecting forward and rearward. It is one in which a single core is buried.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a segment tire having the above structure, wherein when mounted on a wheel, front and rear protruding portions are assembled toward the front and rear in the circumferential direction of the wheel. Therefore, when this is used for traveling as a wheel, the crown portion of the segment tire is always in contact with the traveling surface, so that the generation of vibration and noise is extremely small.

[0007] Since the front and rear projecting portions of the adjacent metal cores are incorporated into each other, even when a lateral force is applied to the wheel, the side surface of the projecting portion is perpendicular to the lateral force. In such a case, a large traction can be obtained in order to counteract the problem, and a wheel with less lateral displacement can be provided.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The segment tire of the present invention will be described below in more detail with reference to the drawings. FIG. 1 is an exploded plan view of the segment tire of the present invention, FIG. 2 is a sectional view taken along line AA, and FIG. 3 is a sectional view taken along line BB. In the figure, reference numeral 1 denotes a rubber elastic body constituting the segment tire 10;
Is a metal core embedded on the bottom 1a side of the segment tire. 1b is a portion projecting forward of the segment tire, and 1c is a portion projecting rearward. That is,
The segment tire in this example has a Z-shape in a plan view, and is mounted on a wheel by sequentially combining the protruding portions 1b and 1c. In the drawing, reference numeral 3 denotes a bolt welded to a cored bar, which is provided for mounting to a wheel.

As can be seen from this example, when the wheel of the present invention rotates in the direction of the arrow, the running surface is always in contact with the crown portions 1d of the front and rear protruding portions 1b and 1c of the segment tire. In addition, the generation of vibration and noise is extremely reduced. On the other hand, when a force is applied in the lateral direction of the wheel, the side portions 1e of the front and rear projecting portions 1b and 1c are formed.
But the traction is large because it opposes this force at right angles,
The occurrence of sideslip is reduced as a wheel. Of course, the front projection 1b and the rear projection 1c are incorporated into the wheel when it is mounted on the wheel, and its position is naturally regulated, and there is almost no difficulty in mounting. .

In the above-described embodiment, the Z-shaped core 2 embedded in the bottom portion 1a is used as shown in the figure. However, as shown in FIG. Of course may be two independent metal cores.

In the segment tire of the present invention,
Although not shown, the rubber elastic body 1 may of course have a hollow portion and a spacer portion.

FIG. 7 is an exploded plan view showing a conventional rectangular segment tire mounted on a wheel, and FIG. 8 is an exploded side view thereof. As can be seen from this example, in the conventional adjacent segment tire 10, a gap S exists between the crown portions 1d, so that the segment S comes into contact with the running surface intermittently. This is accompanied by generation of noise.

FIG. 5 shows another example of the segment tire 10 of the present invention. In the separate cored bar 2 embedded in the protruding portions 1b and 1c, the standing position of the bolt 3 is determined by the width of the wheel. It is arranged in the direction.

FIG. 6 is a plan view showing still another example of the segment tire 10 according to the present invention. In this example, a center portion has a forwardly projecting portion 1b, while a rearwardly projecting portion 1c is provided.
It is an example provided with a pair.

[0015]

According to the present invention, it is possible to provide a wheel which is free from vibration and noise when it is used for traveling and has a large traction in this direction even when a lateral force is applied. It is a thing.
