Problems solved by technology

[0003] However, since the arrangement of the layers of the carcass cords is parallel to each other and radially arranged, and forms an angle of 90 degrees with the centerline of the crown, and the cords on the side of the carcass are radially arranged from the center of the carcass ( That is to say, the extension lines of the cords all intersect at the center of the carcass), and the force of the tire in use is mainly radial force, so, in actual use, the steel ring at the inner ring of the carcass and the The lagging bears a large force, and it is prone to the problem of cord piercing when the load is large

Embodiment

[0016] Such as figure 1 , figure 2 As shown, the present invention is a novel radial tire, which includes a carcass layer 4, a belt layer 3, a protective layer 2 and a crown 1 from inside to outside, and the carcass layer cords 41 are distributed in parallel on one side of the tread. And perpendicular to the circumferential line of the carcass, the projections of the carcass layer cords 41 on the sidewall part cross each other to form a network, and their extension lines 5 (virtual lines) are tangent to a specific point coaxial with the circumferential line of the carcass. Circle 6 (this specific circle is a virtual circle), the diameter of this specific circle is 1 / 3 of the diameter of the carcass inner ring. There are three belt cords, which are wound along the tread side of the carcass at an angle of 3 degrees to the circumferential line of the carcass. The density of the belt layer cords 31 is distributed in such a way that the density is higher on both sides and lower ...

Abstract

The invention discloses a novel radial tire comprising a tire body layer, a belt layer, a protective layer and a crown from inside to outside. The novel radial tire is characterized in that cord threads of the tire body layer are distributed on one side of a tire face in parallel and are perpendicular to a circumference line of a tire body, the cord threads of the tire body layer intersects with one another to be in a net shape on the side of the tire in a projection mode, and the extension cord is tangent to a specific circle which is coaxial with the circumference line of the tire body. The novel radial tire can greatly reduce stress of a steel wire ring and the package adhesive on the inner ring portion of the tire body, so that the tire body is more stable and reliable in using.

Description

technical field [0001] The invention relates to an automobile tire, in particular to a radial tire. Background technique [0002] Radial tire is a relatively common tire at present. It has a large ground contact area, good adhesion performance, small tread slip, and small pressure on the ground unit, so the rolling resistance is small and the service life is long; the crown is thick and has a The hard belt layer is not easy to puncture; the deformation is small during driving, which can reduce fuel consumption by 3% to 8%; because of the small number of plies and thin sidewalls, it has large radial elasticity, good cushioning performance, and large load capacity; It has good heat dissipation performance and can adapt to high temperature and high speed driving. [0003] However, since the arrangement of the layers of the carcass cords is parallel to each other and radially arranged, and forms an angle of 90 degrees with the centerline of the crown, and the cords on the sid...
