Abstract
The invention discloses a sub-opening structure and an anti-explosion tire, and belongs to the field of anti-explosion tires. The seam allowance structure comprises apex, a steel wire ring attached to the lower portion of the apex and supporting glue arranged on the inner side of the apex. The height of the apex is 55%-60% of the height of the lower section; 1 # carcass ply and 2 # carcass ply are coated outside the apex and the bead ring; a steel wire reinforcing layer is arranged between the 1 # carcass ply and the 2 # carcass ply on the outer side of the apex; the upper end point of the steel wire reinforcing layer is positioned below the horizontal axis of the section by 20-40mm, and the lower end point of the steel wire reinforcing layer is positioned at the horizontal position of the steel wire ring; and nylon cord fabric is coated outside the 2 # carcass cord fabric and the support rubber. According to the seam allowance structure and the run-flat tire, the seam allowance part is not easy to delaminate, and the durability of the tire is improved.
Description
technical field [0001] The invention belongs to the field of run-flat tires, in particular to a sprue structure and run-proof tires. Background technique [0002] When the car is running, the tire provides friction for the car through contact with the ground, and the safety of the tire has an important impact on the safety of the car. With the improvement of people's living standards and the continuous enhancement of safety awareness, the market demand for safety tires is expanding day by day. [0003] At present, self-supporting run-flat tires have become the mainstream of the safety tire market. Traditional run-flat tires are made of apex, support rubber, reinforcing layers, etc. in order to ensure the support of run-flat driving. Composed of various parts. However, too many parts at the slits can easily lead to stress concentration, which is reflected in the actual situation of delamination and poor durability at the slits. Contents of the invention [0004] The inve...
