Problems solved by technology

However, the number of layers of belt members is large, the heat generation of the carcass is large, and the phenomenon of adhesion and wind between the members is easy to cause early damage to the tire and affect the durability of the radial tire; at the same time, there are many layers of belt members, and the tire The increase in bod

Example Embodiment

[0025] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0026] First define the orientation of the tire: CL represents the center plane of the tire; the horizontal direction in the figure represents the axial direction of the tire, the vertical direction is the radial direction of the tire, and the vertical direction is the circumferential direction of the tire; CL represents the plane close to the tire center. The inside, away from the tire center plane CL indicates the outside.

[0027] Such as figure 1 Shown is a partial cross-sectional view of the first embodiment of the radial tire of the present invention. The tire 1 includes a tread portion 10, a carcass 30, and a belt layer located between the radially lower portion of the tread portion 10 and the radially upper portion of the carcass 30 50. The bead portion 20, the inner surface layer 40 and the bead portion ...

Abstract

The invention discloses a radial tire which comprises a tread part, a tire body and a belt ply, the belt ply comprises at least two steel wire cord fabric layers and wrapping layers, each steel wire cord fabric layer is formed by winding rubber-coated steel wire cords, at least one wrapping layer is arranged above the radial direction of the axial end portions of the two sides of each steel wire cord fabric layer, and the wrapping layers are arranged at the axial end portions of the two sides of each steel wire cord fabric layer in a spiral winding mode. The steel wire cord fabric layers and the wrapping layers are spirally wound, so that the constraint of the tire body can be enhanced, the tread rigidity is improved, and the rolling resistance of the radial tire is reduced; the spiral winding mode can effectively reduce the residual stress of the steel wire cord, the rebound resilience is small, the coating performance is high, the durability of the radial tire is improved, and the operation efficiency is improved while the precision of the radial tire is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a radial tire. Background technique [0002] According to the arrangement of tire carcass cords, tires can be divided into bias tires and radial tires; the cords of the carcass ply of radial tires are arranged at an angle of 90° or close to the center line of the tread and are arranged in a belt layer Pneumatic tires tightening the carcass. As shown in Fig. 8, it is a partial cross-sectional schematic diagram of a conventional radial tire 1', the tire 1' includes a tread portion 10', a bead portion 20', a carcass 30', an inner portion 40' and a bead part (the bead part is not shown, the carcass 30' is turned up at the bead part on both sides of the tire 1'). In order to constrain the carcass expansion of the radial tire, the steel wire belt layer 50' and the cap layer 60' are generally pasted on the radially outer layer of the carcass 30'. Due to the resilience of the steel cord...
