Definitions
- the present invention relates to a radial tire for a construction vehicle for a large shovel loader used at a construction site etc., and more particularly to a radial tire for a construction vehicle suitable for use as a deep groove type tire.
- the angle of the steel cord constituting the belt layer with respect to the circumferential direction of the tire is increased to reduce the shear strain at the belt end generated at the time of load application. It is done.
- the above angle for suppressing the tread of the tread part is set as small as 10 to 30 ° and the internal pressure is filled. The structure that suppresses the growth of the tire outer diameter has been adopted.

- the improvement by adjusting the belt angle (the angle of the cords constituting the belt layer with respect to the circumferential direction of the tire) can not be expected to produce dramatic effects.
- the tread type is L 4 (Rock Deep, in which the tread gauge on the outside of the belt is thickened.
- the outermost layer belt (the belt in the outermost layer in the tire radial direction) is made the widest, and the shear strain concentrated area in the upper part of the belt is separated and the failure core portion is removed. It is effective to suppress the occurrence of separation failure.
- the belt angle with respect to the tire circumferential direction is sacrificed at the expense of cut resistance. You are forced to make it bigger.
- the present invention provides a radial tire for a construction vehicle, in which the tire life is extended by suppressing the occurrence of separation failure at each belt end which does not reduce cut resistance. As an issue.
- the invention according to claim 1 is a steel having a tire outer diameter of 2 m or more and an aspect ratio of 80% or less, and comprising at least six steel belts on the tire radial direction outer side of the steel radial carcass straddling a pair of bead cores.

- This reinforcement belt has a high rigidity contribution rate. For this reason, if it is partially cut by cutting The reinforcement belt should be placed on the innermost layer of the steel belt layer, as this leads to a significant reduction in the rigidity of the tread portion. In addition, if the flatness of the tire is less than 80%, more rigidity than usual is required. Therefore, the belt width should be at least 40% of the tire width. However, if it exceeds 60%, the distortion at the belt end increases and the possibility of occurrence of separation failure increases, which is not preferable.
- the main crossing belt should have a function to prevent penetration at the time of cutting while securing rigidity, and the belt width of the main crossing belt should be 50% or more of the tire width.

- the shear strain due to this compression is concentrated in the center area of the tread portion, while the outermost protective belt end is located away from the central area, so that the separators at the outermost protective belt end are separated. The occurrence of shocks is also suppressed.
- the steel cord of this outermost protective belt has the same direction as the Stino record of the largest width belt (the widest main intersection belt) of the main intersection belts, so the largest main intersection when loaded. It relieves the shear strain that occurs between the belt end and the rubber in the vicinity, and effectively suppresses the occurrence of separation at the widest cross main belt end.
- the belt width of the outermost protective belt is 75% of the tire width in order to place the belt end in that area. It should be above. However, if the belt width of the outermost protective belt exceeds 90% of the tire width, it will be too close to the belt edge force S tire side surface, and it will be easy to be damaged when the cut input from the tire side is entered. ,. [0019]
- As the crossing belt a belt in which steel cords in a direction crossing with the steel cords of the widest crossing belt are arranged is arranged.
- the steel cords constituting the inner protective belt are arranged in the same direction with respect to the direction of the steel cords constituting the belt, and the inner protective belt is wider than this belt, so the widest main crosses The shear strain generated between the belt end in the direction crossing the belt and the rubber in the vicinity thereof is alleviated, and the generation of separation is effectively suppressed.
- the invention according to claim 1 is particularly suitable as a flat type radial tire for construction vehicles for a shovel loader, in which a deep groove of tread type L 4 or more specified by JATMA is formed.
- the invention according to claim 2 is characterized in that the cord diameter of the steel cord constituting the main crossing belt is larger than the cord diameter of the steel cord constituting the reinforcement belt.
