Pneumatic Tubeless Tires

Abstract

The present invention mainly provides a pneumatic tubeless tire, comprising: a carcass, the lower edges of both sides of the carcass are respectively provided with a bead; a coating layer, which continuously covers the bead to the carcass. Inside the carcass, the two ends of the cladding layer are respectively set as an overlapping portion, which is arranged between each carcass and the crown, and the parts on both sides of the cladding layer that are attached to the carcass are respectively set as an inner cladding portion. , each inner surface and cladding layer located in the carcass jointly form a gas chamber; at least one separator is partially arranged on the wall of the gas chamber to isolate the elastic parts and the inner wall of the carcass. And not sticky; an air nozzle group, which is installed between each opening and the through hole, and has a film fixed on the elastic part; an extension piece, which is installed on each film, coating layer and isolation body . The structure design of the cladding layer and the isolation body can improve the rigidity and support of the tire, and improve the durability, air retention and safety.

Description

technical field [0001] The invention relates to a tubeless tire structure, in particular to a tire structure with an airtight structure design of an insulator and an additional covering layer to improve air retention and durability. Background technique [0002] Most of the tires are installed outside the rim and are mostly made of rubber. Because the tire is in direct contact with the ground, the tire will absorb the impact force from the ground when driving. The elasticity of the rubber can buffer the force between the ground and the rim , in order to effectively improve the comfort when driving. [0003] The structure of the tire is roughly composed of the tread rubber layer and the inner multi-layer cord yarn. The extended end of the bead forms a flange-shaped bead, and a steel traveler is embedded inside the bead. Further analysis of the types of tires, there are two common types: "Tubular" and "Clincher". Among them, "Tubular" refers to a tire that is closed in a tubu...

Problems solved by technology

[0009] However, the carcass of the first model patent is only a single layer, so that the overall rigidity and support of the tire are not good; After passing through the sealing sheet, a gasket or spring gasket is used on the other side to press against the inner stopper. However, this design of the pressing structure will easily cause the elastic fatigue of the airtight sheet at the pressing part. As a result, there is a gap between the protruding part and the gas leaks out; at the same time, the airtight sheet of the first model patent is only fixed on the inner edge wall of the tire lip on both sides, and the covering area is small, which is easy to leak after long-term use. From then on, there will be air leakage from the connecting part; in addition, the air nozzle structure of the first new patent is a specially designed air nozzle, which is different from the standard air nozzles in the general market, and cannot be compatible, resulting in high manufacturing and maintenance costs
