Embodiment Construction

[0010] An inner-belted truck tire is provided with an inner belt layer structure 4 between tire inner-layer rubber 5 and carcass cords 3 .

[0011] The manufacturing method is as follows: First, the carcass layer 3, buffer layer 2 and tread rubber 1 are sequentially pasted on the first-stage forming machine and transferred to the second-stage forming drum, slowly inflated and the distance between the two chucks is adjusted to meet the construction specification. requirements, take it off and use it for later use. Then cut the inner belt layer according to the designed angle of 0~30°, stick it on the inner liner glue 5 of the second-stage forming machine head, and finally align the center line of the inner belt layer with the center line of the carcass cord 3 Fit together so that they coincide.

Abstract

A truck tyre with an inner belt ply is disclosed. An inner belt ply structure is disposed between tyre inner liner rubber and a carcass cord. According to the tyre, stability of tyre periphery dimension can be maintained, compression deformation of the tyre can be reduced, the service lifetime of the tyre is prolonged, tread rigidity of the tyre is improved, and tyre deformation and tyre abrasion are reduced.

Description

technical field [0001] The invention relates to a car tire, in particular to a truck tire with an inner belt. Background technique [0002] At present, the tires used for trucks and mining machinery are bias tires. This bias tire has large radial deformation and poor crown rigidity, which reduces the wear resistance and puncture resistance of the tire and increases the rolling of the tire. resistance. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides an inner belt truck tire. [0004] This kind of tire can not only maintain the stability of the tire outer edge size, reduce the compression deformation of the tire, and improve the service life of the tire; but also can improve the tread rigidity of the tire, reduce the deformation of the tire, and reduce the wear and tear of the tire. [0005] The technical scheme that realizes the object of the present invention is: [0006] An inner-belt truck tire includes a bias-...
