本発明は、不整地走行に供される車両用の超低圧空気入
リタイヤに関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an ultra-low pressure pneumatic tire for a vehicle used for traveling on rough terrain.
(従来の技術)
従来、不整地走行用の超低内圧適用タイヤとしてはバギ
ー(Buggy)車用タイヤが知られている。(Prior Art) Buggy tires have been known as ultra-low internal pressure tires for running on rough terrain.
バギー車は主として泥ねい地、草地、雪上、砂上地域を
走行するもので、この種車の使用目的はスポーツ、レジ
ャーあるいは競走である。Buggy vehicles are primarily used for driving in muddy, grassy, snowy, and sandy areas, and these types of vehicles are used for sports, leisure, or racing.
またバギー車は三輪または四輪自動車の場合があり、内
圧は0.15 kg/cd前後のような超低圧が適用さ

ーカスを1プライ両ビード間に亘って適用し、トレッド
部には通常この種の構造においてカーカスのクラウン部
に併用されるベルト層を用いない、いわゆる変形ラジア
ル構造が知られている。The buggy may be a three-wheeled or four-wheeled vehicle, and an ultra-low internal pressure of around 0.15 kg/cd is applied. For this reason, the reinforcing structure of the tire is to use virtually all rubber without reinforcement, to apply a cord layer only in the trend area, or to apply a carcass with cords arranged in the radial direction between both beads of one ply. A so-called modified radial structure is known in which the tread part does not use the belt layer that is normally used in the crown part of the carcass in this type of structure.
一部トレンド部はタイヤの回転軸と平行にブロックまた
はラグを突設し、そして周方向へは突設したブロック列
またはラグを所定間隔をおいて規則的に配列した構造が
知られている。Some trend parts are known to have a structure in which blocks or lugs are protruded parallel to the rotational axis of the tire, and the protruding block rows or lugs are regularly arranged at predetermined intervals in the circumferential direction.
しかしこのようなトレッド構造は、直進走行時に作用す

いは旋回時には、トレッドに周方向に直角に横方向にブ
ロックまたはラグが並んでいる(横溝が平行)と横方向
に作用する力(横力)に対し、地面把持力が不足し、こ
のため操縦性が劣るという問題があった。However, although such a tread structure has no problem with the driving force or braking force that is applied when driving straight, when steering or turning, blocks or lugs are arranged horizontally on the tread at right angles to the circumferential direction ( There was a problem in that the ground gripping force was insufficient in response to the force acting in the lateral direction (lateral force) due to the horizontal grooves being parallel to each other, resulting in poor maneuverability.
斯る観点から、特開昭60−33104号公報で開示さ
れている不整地走行車両用空気入りタイヤがある。From this point of view, there is a pneumatic tire for vehicles traveling on rough terrain disclosed in Japanese Patent Application Laid-Open No. 60-33104.

る点にある。(Means for Solving the Problems) The present invention has a tread 2 located in the center that is toroidally connected to both sidewalls 3, and a large number of blocks 8 arranged in the lateral direction on the circumference of the tread 2, and in the circumferential direction. In the tires 1 arranged in a herringbone pattern, the purpose is to improve the traction force without reducing the maneuverability (drivability) during running by devising the shape and arrangement pattern of the blocks 8. The technical measures taken to achieve this are such that each of the blocks 8 is aligned with the tire equator line L-
The angle α with respect to L is 90° < α125°, the rows of blocks 8 in the circumferential direction overlap 10 in the lateral direction, and the rising angle β of the blocks 8 on the rotational direction side and the opposite rotational direction When the rising angle θ on the side is set, β is larger than θ, and each block 8 has a linear kick surface 11 parallel to the α on the rotation direction side, and each block closer to the tire equator side The kicking surface 11 of each block 8 adjacent in the lateral direction with respect to the extension plane 14 of the kicking surface 11 of No. 8 is formed in a portion that does not protrude in the rotational direction.
(作 用)
タイヤ1が矢示9方向に回転駆動されると、各ブロック
8の蹴面部11によって、泥、砂、雪等の路面上をかき
込み車両は走行される。(Function) When the tires 1 are rotationally driven in the direction of arrow 9, the kick surfaces 11 of each block 8 scrape mud, sand, snow, etc. on the road surface and the vehicle runs.
このさい、ブロック8は周方向に関し才の列が横方向に
オーバラップ10されていることによって、ブロック8
が所謂不規則配置となって、牽引効果がいかなる接地面
部においても発揮される。At this time, the blocks 8 are arranged so that the rows of the blocks 8 overlap in the lateral direction in the circumferential direction.
are so-called irregularly arranged, and the traction effect is exerted on any contact surface.
また、各ブロック8はその回転方向側の立上り角βと回

は泥、砂等が非吸着性を発揮し、反蹴面部12は、吸着
した泥、砂等が剥離し易くなり、これによって、牽引力
が低下することを防止している。In addition, since each block 8 has an angular difference between the rising angle β on the side in the rotation direction and the rising angle θ on the opposite side in the rotation direction, the kick surface portion 11 on the uneven ground such as mud, sand, snow, etc. The anti-kick surface 12 exhibits a non-adsorption property for mud, sand, etc., and the adsorbed mud, sand, etc. are easily peeled off from the anti-kick surface portion 12, thereby preventing the traction force from decreasing.

The bead portion 4 has bead cores 5 that are continuous in a heteroidal manner, and each bead core 5 is connected by a carcass ply 6 wound thereon.

置されている。On the tread 2, a large number of lugs or blocks (hereinafter collectively referred to as blocks) 8 having a generally rectangular planar shape are arranged in the lateral direction and arranged in a herringbone pattern in the circumferential direction.
' In the block 8, the so-called central block located on the tire equator line L-L is shaped like a plane, and extends at an angle α in the left and right directions alternately at a predetermined pitch in the circumferential direction in the tire rotation direction 9. In this example, on the extension line of this central block, two intermediate blocks and one intermediate block on the left and right are alternately arranged in the circumferential direction at an angle α, so that they are arranged in a herringbone pattern in the circumferential direction.

る(第4図、第5図参照)。Here, the angle α90°<α125°. In other words, if α is 125° or more, the bearing will wash away the road surface, etc. as shown in Figures 4 and 5, and the traction force will decrease. If α is 90° or less, it will not be able to move on muddy, sandy, or snowy roads. This is because if it is pushed in too much, it becomes difficult to obtain a flotation effect, and running performance and traction performance drop sharply (see Figures 4 and 5).

低下されるのが防止されている。That is, β, -θ-3° ~ 20°, θ = 90° ~ 13
2 degrees, β = 93 degrees to 135 degrees, and by making a difference in the block cross-sectional inclination angles β and θ, it is possible to prevent mud from forming on the block 8 on the opposite side 11 on mud, sand, or snow. , sand, snow, etc. become difficult to adsorb, and in the vertical section 12, the mud, sand, snow, etc. adsorbed to the block 8 are promoted to peel off, and the mud, sand, etc. are adsorbed to the tire 1 and the traction force is increased. is prevented from being lowered.

The opposite surface portion 11 that is adjacent in the lateral direction is formed in a portion that does not protrude in the rotational direction.
