Description

Mountain truck explosion-proof tire

Technical Field

The utility model discloses an explosion-proof tire for a mountain truck and belongs to the technical field of tire products.

Background technique

The tire is a carcass of a toroidal elastic rubber product structure. The carcass is usually installed on a metal wheel hub, which can support the vehicle body, buffer external impact, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces and high and low temperature effects when 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 flexibility resistance, as well as low rolling resistance and heat generation. Traditional pneumatic tires often encounter tire blowout problems, such as over-inflation, under-inflation, cracks in the tires, or direct punctures. In order to prevent accidents during driving, it is necessary to frequently check the degree of tread wear and detect tire pressure and temperature information. In the actual driving process of a car, it is easy to cause a car tire blowout due to external factors. Once a car blows out, it will lose balance, resulting in a more serious safety accident. Existing cars lack protective devices for car tire blowouts, which leads to great damage to personnel caused by accidents after car tire blowouts. In particular, car tires are prone to blowouts when road conditions are poor or the car is driving at high speeds, which can easily lead to dangerous situations such as the car losing control and even endangering the lives of the driver and passengers.

Utility Model Content

The technical problem to be solved by the utility model is that the single air chamber of the existing tire will deflate after the tread is damaged, causing a tire blowout and causing the car to lose control.

The utility model solves the technical problem by adopting the following technical solution: a mountain truck explosion-proof tire comprises a carcass, wherein a partition is arranged in the carcass, the partition divides the interior of the carcass into an inner chamber and an outer chamber, a plurality of cylinders are arranged at intervals in the circumferential direction in the outer chamber, the two ends of the cylinder are connected to the two inner side walls of the carcass as a whole, and the inner chamber is connected to the cylinder in one direction.

Among them, in the above structure, an inflation tube is arranged on the partition, and the inflation tube enters from the inner chamber, penetrates through the partition and then extends into the cylinder.

Furthermore, a one-way valve is provided on the inflation pipe in the above structure.

Furthermore, in the above structure, a partition plate is provided in the middle of the cylinder, the partition plate divides the cylinder into an outer cavity and an intermediate cavity, and air holes are provided on the partition plate.

Furthermore, in the above structure, the number of the inflation tubes corresponds to the cylinder body.

Wherein, the number of the cylinders in the above device is 28 to 32 and they are evenly distributed.

Wherein, the tread side of the carcass in the above device is provided with a puncture-proof cushion layer.

The beneficial effects of the utility model are as follows: the structure actually divides the traditional vacuum tire into three layers, namely, the outer cavity, the middle cavity, and the inner cavity, wherein the outer cavity and the middle cavity are annular cylinders, and are divided into about 30 independent and closed chambers with circular cross-sections by the side walls. There are air holes on the side walls between the chambers corresponding to the outer cavity and the middle cavity, a one-way valve is installed in each chamber of the middle cavity, an inflation valve is installed in the inner cavity of the tire, and a layer of anti-puncture cushion is installed outside the outer cavity. This structure makes the materials of all the side walls and chambers consistent with the outer tire. When a tire blows out while the car is driving, it will only cause the air chamber at the corresponding position to be damaged, causing the air chamber here to be deflated. Since each air chamber is independent, other air chambers will not be deflated due to damage at a certain position of the tire. This ensures that the overall structure of the tire will not be damaged when a tire blows out, and can continue to support the tire to continue driving, avoiding a sudden tire blowout and causing the car to lose control.
