Abstract

The invention relates to a manufacturing method of an air-filled tubeless tire for a flat tire rim; the manufacturing method is characterized in that: 1) a bag-opening supporting mould is ready, the mould is cut into a left semi-circle sheet and a right semi-circle sheet which are symmetrical along the circumstantial direction, and the mould is divided into three sections or a plurality of sections equally along the radial direction; 2) the bag opening support is manufactured according to the shape and size of the mould; 3) the head part of the bag opening support is arranged in the mould; 4) the bag opening support and the left and right semi-circle sheets of the mould are sequentially filled in the tire along the outside of a tire bead opening, the root part of the bag opening support is arranged between the tire and a rubber bag, the mould above the head part is parallel to the tire bead opening and is initially positioned by non-setting adhesive paper; 5) a raw tire provided with the bag opening support and the mould is arranged in a tire vulcanizing tank; 6) after the finished product of the tire is manufactured, the forming mould of the bag opening support is taken out, and a bag cover sealing button which is pre-manufactured is matched. The manufacturing method of the invention ensures the effect of the bag opening support without changing the existing manufacturing equipment and technology or changing the existing manufacturing equipment and technology a little, the method is simple, the process is practical and the manufacturing cost is low.

Description

technical field [0001] The present invention relates to a method for manufacturing vehicle tires, in particular to a method for manufacturing a tubeless pneumatic tire for flat rims. Background technique [0002] At present, the commonly used tires of vehicles have two kinds of inner tube pneumatic tires and tubeless pneumatic tires. [0003] Pneumatic tires with inner tubes generate a lot of heat due to high-speed movement, including the heat generated by mechanical friction between the outer tire and the ground, and the heat generated by the buffer layer of the outer tire due to movement and continuous deformation of the tire during exercise. The heat generated by mechanical friction, especially in areas and seasons with high temperature, because the rubber is limited by the temperature limit, the vehicle is very likely to cause a tire burst during high-speed movement, which may cause a vicious accident; because the inner tube is a very thin The airtight layer of the inne...
