Problems solved by technology

[0005] The purpose of the present invention is to provide a pneumatic radial truck tire, which is equipped with a special shaped annular dish-shaped groove on the side of the tire shoulder, so as to eliminate the situation of stone trapping and reduce the wear on the end of the tire shoulder, and further solve the problem even if it is subjected to repeated stress. It will not cause many problems such as cracking at the bottom of the groove, so as to reduce the step wear of the shoulder part of the load-bearing all-steel radial tire

Embodiment Construction

[0023] See attached picture.

[0024] The heavy-duty pneumatic all-steel radial tire involved in the present invention has several main grooves (3 positions shown in Fig. 3) extending in the circumferential direction at the crown part (2 positions shown in Fig. 3) and contacting the road surface. The running surface of truck and bus all-wire radial tires has at least one lateral side surface of the outer contour inclined radially inward from the crown end, and a strip is actually continuous in the circumferential direction and also continues in the radially inward direction. A curved annular dish-shaped groove (part 1 as shown in Figure 3), the annular dish-shaped groove is located from the end of the crown toward the radial inward, the depth of the main groove depth (shown in Figure 3, H) 20 %~160%. The radius (R shown in Figure 3) of the arc surface of the inner side wall of the annular dish-shaped groove is 5%-18% of the width of the tire crown (W shown in Figure 3). The width ...

Abstract

The invention relates to an inflated radial truck tire. The existing inflated tire, in particular to the inflated radial truck tire, has the step abrasion phenomenon on the end of the strip pattern which is positioned at two ends of the driving surface, and greatly reduces the service life of the tire. The invention places a ring-shaped disk groove with the appropriate shape and position at the tire shoulder, which is continuously positioned along the circumference of the tire and extended toward the inner direction of radial direction, for decreasing the ground contact pressure of the end of the tire shoulder, thereby inhibiting the occurrence of the step abrasion of the tire shoulder and eliminating the bad phenomenon of seizing stones. In addition, a specified arc shape is designed on the bottom of the ring-shaped disk groove, even if the tire shoulder suffers the strong lateral force and consequently the repeated distorsion is generated, the groove bottom can not generate the tearing failure.

Description

Technical field [0001] The present invention relates to the improvement of pneumatic radial tires, especially the crown improvement of all-wire radial tires used for trucks, buses and other heavy-duty all-steel radial tires, so as to effectively suppress the abnormal wear of the tread shoulders of the all-steel radial tires. Background technique [0002] Ordinary pneumatic truck radial tires will have stepped wear at the ends of the strip pattern at both ends of the running surface, such as figure 1 As shown in the parts a, b, and c, this is one of the most common abnormal wear of tires, especially the tires installed on the front wheel position of the vehicle and other freely rotating axles. Such wear is abnormally obvious. The main reason for this stepped wear is that the outer diameter of the tire in the shoulder area is smaller than the outer diameter of the tire in the middle area of ​​the tire, and the difference in outer diameter causes the shoulder area to be dragged, (s...
