Embodiment Construction

[0013] An inner-belted truck tire is provided with an inner belt layer structure 4 between tire inner-layer rubber 5 and carcass cords 3 .

[0014] 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 the inner belt layer is cut according to the designed angle of 0~30°, and pasted on the inner liner glue 5 of the second-stage forming machine head, and finally the center line of the inner belt layer and the center line of the carcass cord 3 Fit together so that they coincide.

Abstract

The invention discloses a truck tyre with an inner belt and a manufacturing method thereof. An inner belt layer structure is arranged between tyre inner liner compound and a tyre body cord. The manufacturing method comprises the steps of firstly, orderly attaching a tyre body layer, a buffer layer and tread rubber on a section of forming machine to transfer to two sections of assembly drums; slowly aerating and adjusting the distance between two chucks so as to conform to the requirements of a construction sheet, and taking down for use; then cutting the inner belt layer according to the designed angle of 0-30 degrees, attaching the inner belt layer on the inner liner compound of two sections of forming machines, and finally attaching the center line of the inner belt layer and the center line of the tyre body cord together so as to overlap the inner belt layer overlaps and the tyre body cord. The tyre not only can keep the stability of the physical dimension of the tyre, reduces compressed deformation of the tyre, prolongs the service life of the tyre, but also can improve the tread stiffness of the tyre, alleviates deformation of the tyre, and reduces abrasion of the tyre.

Description

technical field [0001] The invention relates to an automobile tire, in particular to an inner-belt truck tire and a manufacturing method thereof. 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 purpose of the present invention is to overcome the disadvantages of the prior art, and provide a kind of inner belt truck tire and its manufacturing method. This kind of tire can not only maintain the stability of the size of the outer edge of the tire, reduce the compression deformation of the tire, and improve the service life of the tire; but also can improve the rigidity of the tread of the tire, reduce the deformation of the tire, and reduce the wear of the tire. [0004] The technical scheme t...
