- a tire for one-cycle-one-cycle (hereinafter referred to as "tire") has a plurality of main blocks 2 scattered on a tread portion 1.
- the main feature of the configuration of the present invention is to improve the traction performance and the skidding performance without deteriorating the mud-removing property, especially in muddy ground.
- a rubber sub-block 3 having a block height H 2 lower than the height HI of the main block 2 is disposed, and the sub-block 3 is a part of the rubber forming the top 9.
- the inventor conducted a study to satisfy both the traction performance and the skidding performance without deteriorating the mud repellency, especially in muddy ground, and found that between the main block 2 of the tread section, By installing the sub-block 3 whose block height H2 is lower than the height H1 of the main block 2, the mud flow between the main blocks 2 will be completely completed. It is possible to create both the tractive performance and the skidding performance without significantly deteriorating the mud repellency, because it can create a resistance that blocks a part of the mud flow without interrupting the mud flow. I found what I could do.
- the inventor prototyped various tires having different shapes of the sub-block 3, particularly the shape of the top 9, and examined the relationship between the top shape and each of the above-described performances.
- traction performance and skid performance can be further improved, and mud repelling properties can be improved. They found that there were cases where they could be improved, and completed this invention.
- the corner of the sub-block is chamfered, or the BB section shown in FIG. It is preferable to provide a depression 11 in the center of the upper surface 5 as described above, and by taking such a measure, the top 9 of the sub block 3 can easily enter the muddy land, so that the so-called spike effect is enhanced. Thus, both the traction performance and the skidding performance can be improved.
- the chamfers shown in FIGS. 1 (a) to 1 (c) are performed, since the mud easily passes over the sub-block 3, the mud discharging property is also improved.
- the auxiliary block 3 is preferably disposed between the main blocks 2 and 2 adjacent to each other in the tire width direction w as shown in Fig. 1 (a). If side-slip performance is particularly important, it is preferable to arrange it between the main blocks 2 adjacent to each other in the tire circumferential direction c, and it is necessary to improve both traction and sideslip performance in a well-balanced manner. In this case, it is preferable to dispose it between the main blocks 2 adjacent to each other in the direction inclined with respect to the tire circumferential direction c.
- the sub-block 3 may be disposed between two or more main blocks 2 among the above-mentioned three main blocks 2 if necessary.
- the negative rate is preferably 65 to 97%. If the negative rate is less than 65%, clogging of mud is likely to occur, and the traction performance is reduced. 0304790
- the tread curvature ratio obtained by dividing the distance measured along the tire radial direction between the tire section height position and the tread end position by the tread width is preferably 0.20 to 0.50. Since the motor cycle uses the so-called camber running method in which the vehicle leans, the tread curvature ratio is less than 0.20, so the ground contact area of the tread during cornering becomes too small and steering stability decreases. If it exceeds 0.50, the contact area of the tread during straight running becomes too small, and the straight running stability decreases.
- the block area ratio which is the ratio of the total area of the upper surface 5 of the sub-block 3 to the total area of the upper surface 6 of the main block 2, is 0.05. Preferably it is ⁇ 1.2. If the block area ratio is less than 0.05, the number of the sub-blocks 3 is too small, and the traction performance and the skidding performance cannot be sufficiently improved. This is because the interval of 3 becomes too narrow, the mud repellency decreases, and clogging occurs.
- the block height ratio which is the ratio of the block height H2 up to the upper surface 4 of the sub-block 3 to the block height HI of the main block 2, is 0.3 to 0.8. If the block height ratio is less than 0.3, the height of the sub-block 3 is insufficient, and the traction performance and the skid performance cannot be sufficiently improved. This is because the mud repellency decreases and clogging occurs.
- the negative ratio be 75 to 97% and the block area ratio be 0.2 to 1.2. Since particularly complicated steering operations are required for the front wheels in the motor and motor cycle, setting the negative ratio and the block area ratio to a high value will improve the skidding performance. JP03 / 04790
- the negative rate be 65 to 85% and the block area ratio be 0.05 to 0.5.
- the negative ratio and the block area ratio low may improve traction performance and skidding performance in particular. Because it is profitable.
- the sub-block 3 preferably has a ratio of the area of the top surface 5 of the top 9 to the area of the top surface of the bottom 10 of 0.2 to 0.8. If this ratio is less than 0.2, the rigidity of the block above the sub-block 3 will be insufficient, and if it exceeds 0.8, the mud will not be able to exhibit rapid mud spraying properties. is there.
- the ratio of the height H3 of the bent portion 8 in the tire radial direction to the block height H2 of the sub-block 3 is preferably 0.5 or more and less than 1.0. If the ratio is less than 0.5, the resistance to the flow of mud is weakened, and the tractive performance and the skid performance may be reduced. This is because the bent portion 8 is not provided, and the mud repelling property is not improved.
- the shape of the sub-block 3 is smaller than the dimension W in the tire width direction.
- the tire circumferential dimension L is long. Since the sub-block 3 has a long shape in the tire circumferential direction c, it exhibits a large resistance to mud flow in the tire width direction w and can improve the skidding performance, and at the same time, is short in the tire width direction w. This is because the shape makes it easier for the mud flow in the tire width direction w to get over the sub-block 3 and to ensure the mud repellency. Tires having such characteristics are particularly suitable for rear wheel tires requiring high sideslip performance.
- the tire according to the present invention is used as a pneumatic radial tire for one motor cycle.
- high modulus ply materials can be used and side height can be reduced.As a result, it is possible to secure side rigidity and improve cornering performance without reducing the ability to absorb irregularities on the road surface on uneven terrain. Can be done.
- a recess 11 having a height lower than the surroundings may be formed on the upper surface 5 of the sub-block 3, and the planar shape of the upper surface 5 of the sub-block 3 may be a donut shape.
- the block height H2 of the sub-block 3 may be different for each sub-block.
- at least the upper surface 5 of the sub-block 3 located in the central region of the tread may be configured to reduce its area.
- the planar shape of the sub-block 3 is a polygon such as a square, a circle such as an ellipse or a perfect circle, a shape combining a straight line and an arc, and an arc and an arc.
- Various shapes such as a combined shape and a shape provided with a recessed portion 11 as shown in FIG. 6 (b) can be adopted.
- the tire of Example 1 is a motorcycle bias tire having the tread pattern shown in FIG. 1 and the specifications shown in Table 1.
- a prototype of a motorcycle bias tire (Comparative Example 1) having the tread pattern shown in FIG. 8 and the specifications shown in Table 1 was also manufactured.
- the tires of Example 1 and Comparative Example 1 each consist of two bias plies rubber-coated with a nylon cord whose carcass extends at an angle of 30 degrees to the radial direction.
- the tire of Example 2 is a radial tire for one cycle of a motor having the tread pattern shown in FIG. 1 and the specifications shown in Table 2.
- Example 2 (Comparative Example 2) was also prototyped. Each of the tires of Example 2 and Comparative Example 2 was composed of two layers of rubberized rubber belt of aramide cord and one belt reinforcing layer of rubberized nylon cord.
- the tires of Examples 3 to 6 are motorcycle bias tires having the tread patterns shown in FIGS. 2 to 5 and the specifications shown in Table 3, respectively.
- prototypes of a tread pad shown in FIGS. 9 and 10 and a motorcycle bias tire having the specifications shown in Table 3 were also produced.
- Each of Examples 3 to 6, Comparative Example 3 and Comparative Example 4 is composed of two bias plies rubber coated with a nylon cord whose carcass extends at an angle of 30 degrees to the radial direction.
- test specimens were assembled on the rim shown in Table 3 and Tire pressure: 80 kPa, tire load: A running test was performed under load conditions equivalent to a single passenger.
- Example 1 The tires of Example 1, Example 2, Comparative Example 1 and Comparative Example 2 were mounted on rear wheels. At that time, the tire of Comparative Example 3 was mounted on the front wheel.
- the traction performance, skidding performance, and mud-repelling performance when traveling on uneven terrain with a single motor cycle equipped with each test tire were evaluated by filling up with a professional rider.
- the radial tires for rear wheels were also evaluated for their rigidity and the ability to absorb irregularities.
- Tables 4-6 The results are shown in Tables 4-6.
- Tables 4 to 6 are all shown as index ratios with a perfect score of 10 points. In each case, the larger the value, the better the performance. Table 4
