Abstract
The present invention provides a method for improving the construction process of a wide-base radial truck tire, and the improvement of the tire construction process is realized by the design of carcass ply, the tire belt drum and the tire semi-finished components. The invention solves the problem of carcass bending, and provides theoretical guidance and technical support for improving the performance of wide-angle radial tires. The design method of the belt drum of the tire molding machine effectively controls the cords elongation of the belt. In addition, the problem of uneven force in the cords of the belt is eliminated, which dispels the abnormal flow of the wide-base tire shoulder rubber to the center of the crown during the shaping process, thus improving the durability and operability of the tire. The proposed semi-finished components design method in this invention can accurately design the tire semi-finished parts material distribution map, significantly improve the finished tire and the theoretical design of tire material distribution consistency, thus reducing tire development cycle and development costs.
