Description

High-strength fiber material radial tire

Technical Field

The utility model relates to a tire technical field, in particular to high strength fiber material radial tire.

Background

The semi-steel tire consists of an inner liner, a tire body, a tire bead, a tire crown, a belted layer and other important components, wherein the belted layer is positioned between the tire body and the tire crown strip and plays a role in supporting the tire tread and protecting the tire body inside. The tyre cord is not arranged in a cross way, but is approximately parallel to the outer tyre section, when the tyre is in a running process, the stress around the crown part is increased, the circumferential extension can be caused, and the tyre body becomes a radial crack, so that the buffer layer of the tyre adopts an intersecting cord layer which is arranged in an approximately circumferential way, a rigid annular belt which can not be extended almost is formed, the whole tyre is fixed, the circumferential deformation of the tyre is limited, the rigidity of the tyre surface on a dry and wet road surface is ensured, and the ground holding force when the tyre is in an ice surface running is also improved.

In the prior art, a cushion layer adopts a belt ply, and because the change of the size of the inflation section of the tire is related to the tensile rigidity of the belt ply, the too low tensile rigidity can cause the section of the tire to be heightened and narrowed, and the outer diameter, the tread curvature, the grounding length and the grounding area are correspondingly increased; the ground width is reduced. Meanwhile, the rigidity of the tire in the circumferential direction and the lateral direction is weakened, and the rolling resistance and the temperature of the tire are increased. When the tensile rigidity is too large, the rolling resistance tends to increase, and the temperature of the tire sharply increases in a straight line. Therefore, the common tire has the problems of poor stability, weak rigidity and the like in the road running process, and how to design the belt structure to ensure that the tensile rigidity of the belt layer is kept in a reasonable range becomes the current technical problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the problem that exists among the known prior art, for this reason the utility model provides a high strength fiber material radial tire can make the tensile rigidity who restraints the layer keep at reasonable scope.

In order to achieve the above object, the utility model provides a high strength fiber material radial tire, it includes: the tire comprises a tire crown, tire shoulders, tire sides and tire beads which are connected into a whole are sequentially arranged on two sides of the tire crown from top to bottom, and the tire also comprises a tire body which is attached to the inner surfaces of the tire sides and the tire beads; the lower end of the tire body is wrapped by the bead filler and the bead ring; the steel wire ring is positioned at the lower end of the triangular glue; crescent buffer rubber strips are arranged on the two sides of the tire body in the tire shoulder area; the upper end of the buffer rubber strip is sequentially provided with a belt ply A and a belt ply B from bottom to top; both sides of the upper part of the belt ply B are respectively provided with a covering layer and a belt ply C from bottom to top; the belt layer A, the belt layer B, the covering layer and the belt layer C are positioned on the inner crown ring; the belted layer A, the belted layer B and the belted layer C are made of high-strength and hard-to-stretch fiber materials.

Further, the belt A, the belt B and the belt C are made of steel wires.

Further, the belted layer A, the belted layer B and the belted layer C are made of steel wire aramid fibers.

Compared with the prior art, the beneficial effects of the utility model are that: the belt ply C is added, so that the stability of straight line running can be effectively improved; the high-strength and hard-to-stretch fiber material is used, so that the rigidity of the tire is increased; the whole structure is simple, and the batch production is facilitated.
