Description

Technical Field

[0001] This invention belongs to the field of tire technology, specifically relating to a fast-repairing and explosion-proof tire with a multi-layered reinforced skeleton, which is especially suitable for passenger vehicles and two-wheeled electric vehicles, solving the problems of structural stability and stress tear resistance of tires under high-speed driving. Background Technology

[0002] In existing technologies, it is often difficult to balance tire puncture resistance and ease of maintenance. Currently common pneumatic honeycomb tires typically use a single high-hardness rubber material for their carcass to meet load-bearing and deformation resistance requirements. This not only results in poor overall vehicle shock absorption and low driving comfort, but also means that once a part of the tire is worn or damaged, it must be scrapped entirely, and cannot be repaired or replaced.

[0003] In addition, some simple split-type airbag tires have appeared on the market. Although they achieve partial replaceability by opening mounting holes and inserting independent airbags, their structure still has obvious shortcomings: First, the airbag mounting holes lack effective circumferential constraints. Under the action of centrifugal force at high speeds, the edges of the airbag holes are prone to "petal-shaped" outward deformation, resulting in periodic vibration and abnormal noise. Second, the holes will generate severe stress concentration when under heavy loads or turning in place, which can easily lead to tearing of the hole wall rubber with long-term use. Third, there is a lack of efficient rigid torque transmission path between the wheel hub and the tire crown, resulting in a lag in rapid acceleration response.

[0004] The existing technology lacks a combined reinforced frame structure that can effectively balance resistance to centrifugal deformation, resistance to orifice shear stress, and improvement of overall transmission stiffness. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a quick-repairing explosion-proof tire with a reinforced skeleton, which solves the above-mentioned technical defects through internal multi-layered reinforcing components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick-repairing and explosion-proof tire with a reinforced skeleton, comprising a tire body and an airbag mounting hole formed on the tire body. A first circumferential reinforcing member is provided inside the wall of the airbag mounting hole; a second circumferential reinforcing member is provided inside the tire crown of the tire body; and a third circumferential reinforcing member is provided inside the tire bead of the tire body. Furthermore, radial reinforcing members are also provided within the tire body, connecting the first, second, and third circumferential reinforcing members into a continuously transmitting, integral rigid force-bearing frame.

[0007] The present invention has the following beneficial effects: 1. By using the circumferential reinforcing components inside the tire crown to constrain the centrifugal force during high-speed driving, the tire crown radius is forcibly locked, eliminating the "petal-shaped" regular vibration caused by centrifugal force; 2. Through the synergistic effect of the circumferential and radial reinforcing members at the orifice, the stress on the edge of the orifice is evenly distributed to the overall skeleton, which greatly reduces the shear stress when turning in place and prevents the orifice wall from tearing. 3. The circumferential and radial reinforcement components at the tire bead combine to form an efficient torque transmission path, improving the starting acceleration response between the wheel hub and the tire crown; 4. Because the reinforcing components of each layer are connected to form an integral metal skeleton, the tire body can use a softer, high-resilience rubber compound, which significantly improves the shock absorption comfort of daily driving.

Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings.

[0013] As shown in the figure, the present invention provides a fast-repairing explosion-proof tire with a reinforced skeleton. During the production of the tire body, the circumferential steel wire bundle layer (3), the bead steel wire bundle ring (4), the orifice steel wire bundle ring (2) and the radial reinforcing steel wire layer (7) are pre-assembled to form an integrated internal steel wire skeleton cage.

[0014] Subsequently, a highly resilient rubber material is wrapped around the outside of the steel wire skeleton cage to form a solid green tire blank. The green tire blank is placed in a mold, and an olive-shaped airbag mounting cavity (1) that is "wide in the middle and narrow at both ends" is pressed out inside the green tire blank using a multi-lobed radial shrinkage detachable core mold. After high-temperature vulcanization and removal of the lobed core rods, the finished tire body can be obtained.

[0015] The working principle of the structure of the present invention is as follows: In practical applications, when the tire rotates at high speed, the circumferential steel wire bundle layer (3) of the tire crown acts as the second circumferential reinforcing member, which can effectively resist centrifugal force, forcibly lock the tire crown radius, and prevent the tire surface from bulging outward due to centrifugal force, thereby eliminating regular "petal-shaped" vibration; when the vehicle turns in place or corners at high speed, the wire bundle ring (2) of the orifice acts as the first circumferential reinforcing member, which can evenly distribute the lateral shear stress at the hole wall to the overall skeleton, effectively preventing the hole wall rubber from tearing or fatigue damage. At the same time, the orifice contour at the narrowed ends of the olive-shaped airbag mounting hole (1) and the wire bundle ring (2) of the orifice together form a double axial limit, which effectively prevents the inflated airbag from coming out of the cavity.

[0016] Those skilled in the art will recognize that, without departing from the core concept of this invention, the first circumferential reinforcing member, the second circumferential reinforcing member, the third circumferential reinforcing member, and the radial reinforcing member can also be replaced by reinforcing materials with equivalent strength known in the art, such as nylon cord, polyester fiber cord, aramid fiber cord, and carbon fiber bundle. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope of this invention.

[0017] Preferably, the first circumferential reinforcing member, the second circumferential reinforcing member, and the third circumferential reinforcing member are all closed annular structures that surround the tire body in a complete circle.
