Problems solved by technology

[0006] Aiming at the problems that the existing inflatable hollow tires are complicated to manufacture, poor in shock absorption and poor in air tightness, the invention provides a one-time molding inflatable hollow tire and its manufacturing method. Through the cooperation of the opening structure and the cavity structure, the hollow carcass can be Once molded, the airtight layer can also be easily coated. Install the valve through the valve installation hole to inflate the hollow structure, and cooperate with the airtight layer to form a shock-absorbing chamber with stable air pressure, which greatly improves the shock absorption.

Embodiment 1

[0070] Such as figure 1 with figure 2 As shown, the one-time forming inflatable hollow tire of this embodiment includes a carcass 1, and further includes:

[0071] The cavity structure 10 is opened in the carcass 1 along the circumferential direction, and a hollow cavity is formed in the carcass 1;

[0072] The opening structure 11 is a groove opened on the inner ring surface of the carcass 1 along the circumferential direction, and the opening structure 11 communicates the cavity structure 10 with the outside; and

[0073] The airtight layer 12 is composed of an airtight layer 120 formed on the surface of the cavity structure 10 and an airtight layer 121 that closes the opening structure 11;

[0074] The valve mounting hole 13 is opened on the side of the carcass 1 and connects the cavity structure 10 with the carcass 1.

[0075] Hollow cavities of hollow tires are mostly molded by placing the mold core in the cavity of the molded tire when the tire is made. After the tire cavity is m...

Embodiment 2

[0081] Such as Figure 5 As shown, the one-time forming inflatable hollow tire of this embodiment is further improved on the basis of Embodiment 1. The opening width r of the opening structure 11 gradually increases from the cavity structure 10 to the inner ring of the carcass 1.

[0082] In the tire of this embodiment, the shape of the opening structure 11 from the cross section of the carcass 1 shows a triangular shape from the cavity structure 10 to the inner ring of the carcass 1. The opening structure 11 of this embodiment makes the mold core The take-out operation is easy, and the cavity structure 10 and the opening structure 11 in the carcass 1 are not damaged, and the yield of the hollow tire is high.

Embodiment 3

[0084] Such as Figure 4 As shown, the one-time forming inflatable hollow tire of this embodiment is further improved on the basis of embodiment 1. The opening width r of the opening structure 11 gradually changes from the cavity structure 10 to the inner ring direction of the carcass 1. Decrease.

[0085] In the tire of this embodiment, the shape of the opening structure 11 from the cross section of the carcass 1 is shown as an inverted triangle from the cavity structure 10 to the inner ring of the carcass 1. In the opening structure 11 of this embodiment, after the rim is installed, The two sides of the inner side of the body 1 are compressed to cooperate with the opening structure 11 to form a locking effect. On the one hand, the fastening effect between the rim and the carcass 1 is enhanced, and the safety of the tire is increased. On the other hand, after the rim is compressed The opening structure 11 is more tightly closed and cooperates with the airtight layer 121 to furth...

Abstract

The invention discloses a one-time formed inflatable hollow tire and a manufacturing method thereof and belongs to the field of tire manufacturing. The tire comprises a cavity structure, an opening structure, an air impervious liner and an inflating valve installing hole, wherein the cavity structure is formed in a tire body in the periphery direction, a hollow cavity is formed in the tire body, the opening structure is arranged in a groove in an inner ring face of the tire body in the periphery direction, the opening structure enables the cavity structure and the outside to communicate, the air impervious liner is formed by a first air impervious liner body formed on the surface of the cavity structure and a second air impervious liner body for opening and closing the opening structure, and the inflating valve installing hole is formed in one side of the tire body and enables the cavity structure and the tire body to communicate. According to the tire, by means of cooperation of the opening structure and the cavity structure, the hollow tire body can be formed at a time, the air impervious liner can also be coated conveniently, the manufacturing technology of the tire is simplified, an inflating valve is installed through the inflating valve installing hole to inflate the hollow structure, by means of cooperation with the air impervious liner, a vibration reducing cavity for stabilizing air pressure is formed, and the vibration reducing performance is improved greatly.

Description

Technical field [0001] The invention belongs to the field of tire manufacturing, and more specifically, relates to a one-time forming inflatable hollow tire and a manufacturing method thereof. Background technique [0002] Tires are divided into tube tires and tubeless tires. In view of the current traditional tube tires are widely used because of their mature production technology, cushioning, good riding comfort and good load bearing. However, with tire blowouts, wear and unsteady running, there are more and more vehicle driving safety accidents. Tubeless tires, which have the advantages of high safety, energy saving and environmental protection, have attracted more and more attention. Tubeless tires are divided into two categories: solid tires and hollow tires. Hollow tires largely solve the defect of bumps caused by insufficient resilience of solid tires during riding, but the shock absorption performance is compared with that of the same type of tube tires. There are still ...
