They are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

[0003] At present, the prior art CN202020515464.7 discloses a car tire, wherein two symmetrically arranged water storage bags are connected to the side wall of the tire carcass, and a water guide strip is embedded in the side wall of the water storage bag, one end of the water guide strip is located inside the water storage bag, and the other end of the water guide strip is connected to the crown of the tire carcass. Water is injected into the water storage bag, and the water in the water storage bag is guided to the crown on the tire carcass through the water guide strip, which helps the tire to dissipate the heat generated during driving. The rubber ring is set to protect the water guide strip to prevent the water guide strip from contacting the ground during driving when the tire pressure is low, causing the water guide strip to wear. The rubber strip is set to reduce the contact area between the water guide strip and the air, reduce water loss, and the cord layer is set to enhance the strength of the rubber ring.

[0004] However, the above-mentioned automobile tires all have separate inner cavities. Once a tire bursts while the vehicle is driving, there is no protection measure, which can easily cause a traffic accident and has a low safety factor. Utility Model Content

DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 3 , Figure 1 It is a front view of the utility model. Figure 2 This is a cross-sectional view of the utility model along the direction of the air pressure sharing valve. Figure 3 yes Figure 2 The enlarged view of detail A shows that the utility model provides a dual-protection tire including a first tire 101, a second tire 102, an isolation protection layer 103, a wheel hub 104, an air pressure sharing valve 105, a first tire pressure sensor 106, a second tire pressure sensor 107, a fixing bolt 108 and a valve core. The isolation protection layer 103 has a safety card slot 109, and the valve core includes an inflation plug 110 and a screw cap 111. The above scheme solves the problem that the existing automobile tires have separate inner cavities, tire blowouts during driving can easily cause traffic accidents, and the safety factor is low. It can be understood that the above scheme can be used in scenarios where automobile tires are used.

[0019] According to the present specific embodiment, the first tire 101 is sleeved on the outer side of the wheel hub 104, the second tire 102 is sleeved on the outer side of the wheel hub 104, the isolation protection layer 103 is fixedly connected to the wheel hub 104, and is located between the first tire 101 and the second tire 102, the air pressure sharing valve 105 is fixedly connected to the wheel hub 104, and is communicated with the first tire 101 and the second tire 102 respectively, and is located on the inner side of the wheel hub 104, the double-protection tire provides installation and support conditions for the first tire 101 and the second tire 102 through the wheel hub 104, the arrangement of the first tire 101 and the second tire 102 enables the double-protection tire to have two tire cavities, and through the middle of the first tire 101 and the second tire 102 The insulating protective layer 103 plays the role of isolating the left and right sides. When an accident occurs on one side of the first tire 101 or the second tire 102, the other side can also work normally. The air pressure sharing valve 105 is added to the wheel hub 104. When the air pressure on either side of the first tire 101 or the second tire 102 is insufficient, the air pressure on the other side can be shared. After the first tire 101 or the second tire 102 is punctured, the other side can still work normally, thereby ensuring the stability of the automobile tire pressure. Compared with the existing tires with separate inner cavities, the double-protection tire is safer. If one of them has a tire burst, the other can also work normally, thereby ensuring that the vehicle can be stable and doubling the safety. This solves the problem that the existing automobile tires all have separate inner cavities, and tire bursts during driving are prone to cause traffic accidents, thereby having a low safety factor.

[0020] Among them, the first tire pressure sensor 106 is fixedly connected to the air pressure sharing valve 105 and is located in the first tire 101, and the second tire pressure sensor 107 is fixedly connected to the air pressure sharing valve 105 and is located in the second tire 102. The first tire pressure sensor 106 and the second tire pressure sensor 107 respectively detect the tire pressure in the first tire 101 and the second tire 102 in real time, and upload the detected tire pressure to the car's central control screen for display, so that the user can understand the status of the dual-protection tires in real time.

[0021] Secondly, the fixing bolt 108 is threadedly connected to the wheel hub 104 and passes through the wheel hub 104. The valve core is connected to the first tire 101 and is located on one side of the first tire 101. The setting of the fixing bolt 108 is used to install the wheel hub 104 on the vehicle body. The valve core is used to inflate the first tire 101 and balance the air pressure of the first tire 101 and the second tire 102 through the air pressure sharing valve 105.

[0022] At the same time, the safety slot 109 is located on the side of the isolation protection layer 103 close to the wheel hub 104. The setting of the safety slot 109 makes the connection between the first tire 101 and the second tire 102 and the isolation protection layer 103 more stable.

[0023] In addition, the inflation plug 110 is connected to the first tire 101 and is located on one side of the first tire 101. The screw cap 111 is threadedly connected to the inflation plug 110 and is located on the side of the inflation plug 110 away from the first tire 101. The inflation plug 110 is used to inflate the first tire 101, and the screw cap 111 is used to cover the inflation plug 110 to prevent the inflation plug 110 from leaking.

[0024] The utility model discloses a double-protection tire, which provides installation and support conditions for the first tire 101 and the second tire 102 through the wheel hub 104. The first tire 101 and the second tire 102 are arranged so that the double-protection tire has two tire inner cavities, and the isolation protection layer 103 between the first tire 101 and the second tire 102 plays a role of isolating the left and right. When an accident occurs on one side of the first tire 101 or the second tire 102, the other side can also work normally. The air pressure sharing valve 105 is added to the wheel hub 104. When the air pressure on either side of the first tire 101 or the second tire 102 is insufficient, the air pressure on the other side can be shared. The double-protection tire is used for the double-protection tire, and after any one side of the first tire 101 and the second tire 102 is punctured, the other side can still work normally to ensure the stability of the tire pressure of the automobile. The first tire pressure sensor 106 and the second tire pressure sensor 107 respectively detect the tire pressure in the first tire 101 and the second tire 102 in real time, and upload the detected tire pressure to the automobile central control screen for display, so that the user can understand the status of the double-protection tire in real time. Compared with the existing tire with a single inner cavity, the double-protection tire is safer. If one of the tires is punctured, the other can also work normally, ensuring that the vehicle can be stable and the safety is doubled, which solves the problem that the existing automobile tires have a single inner cavity, and a tire blowout during driving is easy to cause traffic accidents, and the safety factor is low.
