Description

An explosion-proof safety tire structure

technical field

The utility model relates to an explosion-proof safety tire structure, which belongs to the technical field of explosion-proof automobile tires.

Background technique

At present, there are many schemes for explosion-proof safety inner tubes, and their promotion and application are seldom. For example, 202337182U is an explosion-proof safety inner tube, which is composed of a circular cylindrical carcass and a rubber valve. When in use, first place the explosion-proof safety inner tube in the tire cavity of the tubeless tire, then use the air needle to inflate through the rubber valve, and then install the tubeless tire together with the explosion-proof safety inner tube on the rim. The tubeless tire is then inflated through the rim valve. Special attention should be paid to the air pressure after inflation of the tubeless tire and the explosion-proof safety inner tube should be basically the same. When the tubeless tire blows out and deflates, the explosion-proof safety inner tube still supports the tubeless tire to maintain the balance of the car. Another example is 203995497U1, a double-cavity, high-safety tire, which is formed by two concentric sets of homogeneous tires with different diameters. The smaller diameter is the inner tube, and the larger diameter is the outer tire. The inner and outer tires are made of the same rubber material; the tire contains two cavities, one is the inner tube cavity, and the other is the cavity formed between the inner tube and the outer tire; The inner and outer tires and the hub have a common contact surface, and the length of the contact surface is greater than the distance between the inner and outer tire sides, ensuring that as long as one of the two cavities in the tire has air pressure, the sealing between the tire and the hub can be achieved, and the inner and outer tires are still thick tires , does not affect ride comfort. Another example is the 204659361U anti-trap electric vehicle tire, which includes an outer tire and an inner tube. The inner tube is placed in the space formed by the outer tire and the wheel steel rim. Independent first space and second space, the volume of the first space is smaller than the volume of the second space, the first space is placed outside the second space, the anti-punching layer is made of elastic material; A first air port and a second air port are also arranged, the first air port communicates with the interior of the first space through a rubber hose, and the second air port communicates with the interior of the second space.

In summary, the first two inner tubes are thick tires with the same quality as the outer tire. Not only must the air pressure in the inner and outer tire cavities be balanced when inflated, but the relative manufacturing cost is relatively high, and the installation process is complicated, which is not conducive to popularization and existing vehicles. The transformation of tires; the last item, although the inner tube is a soft tire, is provided with an anti-tack layer inside the inner tube. The inner tube is divided into a first space and a second space independent of each other through the anti-tack layer. The first valve is connected to the first space through a rubber hose. Internal communication, manufacturing and installation process is relatively complicated. For this reason, it is necessary to design a new technical solution that can comprehensively overcome the deficiencies in the prior art.

Utility model content

The utility model just aims at the deficiencies of the prior art, and proposes an explosion-proof safety tire structure, which not only overcomes the above-mentioned defects of the prior art, but also has a simple and easy structure, reduces the manufacturing cost and the complexity of the installation, and satisfies the actual use Require.

In order to solve the above problems, the technical scheme adopted by the utility model is as follows:

An explosion-proof safety tire structure, including a safety inner tube, a safety inner tube air nozzle, a rim, a rim air nozzle and a tubeless tire, the safety inner tube air nozzle is assembled on the safety inner tube, and the inner diameter of the safety inner tube is the same as that of the corresponding rim Groove bottom size transition fit; the rim air nozzle is assembled on the rim, and a safety inner tube air nozzle is added to the rim; the safety inner tube is assembled inside the tubeless tire and coaxial with it, so The tubeless tire is coaxial with the rim and is set outside it, the safety inner tube air nozzle is fixedly connected with the corresponding nut thread through the corresponding hole of the rim and the combined washer, and the rim and the safety inner tire air nozzle are Sealing is performed by the combined gasket; both sides of the tubeless tire are respectively stuck in corresponding grooves on both sides of the rim to form an explosion-proof safety tire.

As an improvement of the above technical solution, the section diameter of the safety inner tube is an ordinary elastic rubber inner tube smaller than that of a conventional automobile inner tube, and when rotating at high speed, the safety inner tube is constrained by the rim to minimize the offset.

As an improvement of the above technical solution, after being inflated, the safety inner tube in the tubeless tire can use its own elasticity to balance the pressure inside and outside, so that the pressure difference between inside and outside tends to zero, and its leakage tends to be minimal.

As an improvement of the above technical solution, during normal driving, there is a certain gap between the outer wall of the safety inner tube and the inner wall of the tubeless tire to avoid contact friction, thereby improving the life of the safety inner tube.

As an improvement of the above technical solution, the external pressure of the safety inner tube decreases sharply at the moment when the tubeless tire blows out, and the safety inner tube elastically expands under the action of the internal pressure and fills the inner cavity of the tubeless tire, thereby effectively maintaining The vehicle runs smoothly.

The utility model compares with prior art, and the implementation effect of the utility model is as follows:

The explosion-proof safety tire structure described in the utility model adopts the above-mentioned technical scheme, and the explosion-proof safety inner tube can balance and stabilize the vehicle for several minutes when the tubeless tire blows out, ensuring that the driver can park the car to the emergency lane; in addition, the invention The design principle of the utility model is simple, the structure is compact, and it is convenient for promotion and transformation of existing tires. Within a few minutes of a tire burst, the vehicle can run smoothly, which increases the safety of the vehicle and reduces the impact on other vehicles. actual use requirements.
