Embodiment 1

[0052] A kind of anti-leak airbag cavity tire of the present embodiment, as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, it includes a carcass 1 and a bladder 10, which is a bladder-shaped cavity opened inside the carcass 1, and adjacent bladders 10 are connected in series through passages.

[0053] In order to effectively solve the problem that the vehicle's center of gravity will be out of control due to tire blowout after air leakage occurs, the present invention improves the shape inside the tire carcass 1. 10 are connected to each other through passages to cover the carcass 1 for a week, and the cystic cavities 10 connected in series constitute the cystic cavity skeleton inside the carcass 1 through the cystic cavity wall, which effectively supports the carcass 1 and strengthens the carcass. The strength of the carcass 1; when the carcass 1 inflated with ordinary tires is punctured, the air pressure in the inner cavity decreases rapidly, causing...

Embodiment 2

[0056] A kind of anti-leakage airbag cavity tire of the present embodiment is further improved on the basis of embodiment 1, such as Figure 7 As shown, a reinforcing hole 12 is opened between the tread of the carcass 1 and the bladder 10 .

[0057] There is a cavity between the cavity 10 and the tread as a reinforcement hole 12, and a reinforced anti-tack layer is formed between the reinforcement hole 12 and the tread. One end of the small head is close to the top of the tread, and the reinforced anti-tack layer formed between the reinforced hole 12 and the big head to the tread can play a very good anti-tack effect. When the car is running, the tread that the tire contacts with the ground is very easy to Punctured by sharp stones and nails, the water drop shape of the reinforced hole 12, and the stress concentration between the small head end and the tread, make it difficult for the tire to puncture the tread when it encounters a sharp object while driving, achieving the ant...

Embodiment 3

[0059] A kind of anti-leak airbag chamber tire of the present embodiment is further improved on the basis of embodiment 1 or 2, such as image 3 , Figure 4 and Image 6 shown, also includes

[0060] Air valve holes 11, which are opened on the side of the carcass 1, communicate the bladder cavity 10 with the outside of the carcass 1;

[0061] Air valve 110, which is installed in the valve hole 11 and placed on the side of the carcass 1;

[0062] The valve cap 111 is movably connected to the end of the valve 110 to seal the valve 110 .

[0063] A valve hole 11 is provided on the side wall of the carcass 1, and a bladder 10 is communicated with the outside of the carcass. The valve 110 and the valve cap 111 for tire inflation can be placed on the carcass 1 side through the valve hole 11. Now Some valves 110 are mostly installed on the rim of the inner wall of the tire, and a small part are installed in the groove on the side of the rim, which is troublesome to install, requi...

Abstract

The invention discloses a leakproof airbag cavity tire, and belongs to the field of tires. The leakproof airbag cavity tire comprises a tire body and further comprises bag cavities which are bag-shaped cavities formed inside the tire body; the adjacent bag cavities are connected in series through a channel; reinforcing holes are formed between a tire face of the tire body and the bag cavities; a valve hole formed in the side face of the tire body, an inflating valve installed in the valve hole, an inflating valve cap movably connected to the end of the inflating valve and a sealing plug are further included, and the bag cavities communicate with the outside of the tire body; the inflating valve is placed on the side face of the tire body; the inflating valve cap seals the inflating valve;the sealing plug is fixedly connected to the tail end of the inflating valve cap; and the inner surface of each bag cavity is provided with an airtight layer. According to the leakproof airbag cavitytire, the bag cavities which are connected in series through the channels are arranged inside the tire body, the degree of air leakage when the tire is punctured is greatly reduced, and tire burst caused when the air leaks is prevented; and according to the tire, mastication, mold assembly, injection, mold opening, secondary mold assembly, air injection, vulcanization, pressure relief, airtight layer preparation and secondary mold opening are carried out for direct molding, and production and manufacturing are easy.

Description

technical field [0001] The invention relates to the field of tires, in particular to a tire with an anti-leakage airbag cavity. Background technique [0002] There are generally four reasons for a tire blowout: one is the tire leak, which is caused by the tire itself being damaged or punctured; The air pressure in the tire rises, causing the tire to deform and burst; the third is that the tire air pressure is insufficient, which may easily cause a large resonance force, and may cause the tire wall to burst when turning; the fourth is the performance of the tire itself, which is caused by insufficient balance in tire manufacturing. Wears out quickly, leaving weak spots on the tire that can break easily. Tire leaks can easily cause a tire blowout, and the main cause of an accident after a tire blowout is that the tire suddenly ruptures and causes a large deformation of the tire, resulting in a change in the center of gravity of the vehicle and a loss of control of the vehicle...
