Description

An explosion-proof safety tire

technical field

The utility model belongs to the vehicle explosion-proof tire technology, in particular to an explosion-proof safety tire.

Background technique

The sidewall of the inflated car tire is the main part supporting the weight of the vehicle, especially for some tires with a large aspect ratio (the aspect ratio is the ratio of the height to the width of the tire), the sidewall is very "thick", and the "puncture" is usually severe. It will cause the tire wall to burst instantly, so that the tire will lose its supporting force instantly, and the center of gravity of the vehicle will change immediately, especially if the front wheel of a front-wheel drive vehicle is blown out, the momentary center of gravity transfer after the blowout is likely to cause the vehicle to lose control. Therefore, a kind of "run-flat tire", that is, RSC run-flat tire, has been gradually applied to vehicles in recent years. If the tire is punctured or burst during driving, even if the air pressure in the tire is reduced to zero, the RSC tire can run at a predetermined speed for a certain distance.

There is no big difference in structure between RSC tires and ordinary tires, but a thick layer of reinforcement is made on the sidewall (wall) of the tire, so that the tire can still stand in the state of insufficient air pressure or air leakage. . The structural characteristics of RSC tires, the overall hardness of the tires reduces the absorption of vibrations by the tires when the car is driving, and then directly transmits them to the chassis to filter them out, which in turn leads to a certain decrease in comfort. In addition, because the RSC tires are obviously noisy in driving, the thick and hard tire walls are destined to make a lot of noise when driving.

detailed description

In order to make the content of the utility model more clearly understood, the utility model will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, a vehicle explosion-proof safety tire shown in the utility model includes: a wheel hub 1 and an integrated tire carcass 2 and a valve core 10, and a combined support ring is placed on the integrated tire tire In the body 2, the combined support ring consists of spring steel support rings with concave/convex blocks and elastic washers with concave/convex grooves, and is fixed on the rim 1. Compared with the prior art, the installation method of the combined support ring can greatly improve the strength and shock resistance of the combined support ring, and shorten the distance between the inner wall of the integrated tire carcass 2 and the outer wall of the combined support ring to the greatest extent. The total size of the distance H, usually the distance H is less than 3cm. When the tire bursts, the combined support ring can quickly and effectively support the integrated tire carcass 2 and the vehicle. The rim 1 is a split rim, including a main rim and a secondary rim 4, the secondary rim 4 is fastened to the main rim 1 by bolts 5 to form a fixed whole.

It should be noted that there can be two or more sets of combined support rings, and one set of support rings includes an elastic washer and a spring steel support ring. The number of combinations can minimize distance H according to type and tire size. If the lateral height of the integrated tire is small, it needs two sets of support rings, and if the tire lateral height is large, three or more sets of support rings need to be installed to meet the requirements. When the tire bursts, the combined support circuit can quickly and effectively support the outer tire, so that the change of the tire's action radius can be controlled within the minimum range, which is convenient for vehicle control and ensures driving safety.

As shown in Figures 1 and 2, the combined support rings are provided with two groups, the first group of combined support rings includes a first elastic washer 6 and a first spring steel support ring 7, and the first elastic washer 6 passes through the auxiliary wheel The edge 4 is fastened on the hub 1, the first elastic washer 6 is provided with a first air inlet 61 and a first elastic washer groove 62; the first spring steel support ring 7 is provided with a first spring steel support ring air hole 71 . The first spring steel support ring protrusion 71 and the first spring steel support ring concave block 73 matched with the first elastic washer groove 62 . When the integrated tire carcass 2 is inflated through the valve core 10, the pressure gas is delivered to the inner cavity of the tire through the first air intake hole 61 and the first spring steel support ring vent hole 71, thereby completing the inflation process of the integrated tire. The second group of combined support rings includes a second elastic washer 9 and a second spring steel support ring 8. The second elastic washer includes a second elastic washer convex groove 91 and a second elastic washer groove 92. The second elastic washer 9 passes through the second elastic washer. The two elastic washer convex grooves 91 are fixed on the first spring steel support ring 7 , and the second spring steel support ring 8 is provided with a second spring steel support ring protrusion 81 matching with the second elastic washer groove 92 .

The explosion-proof safety tire has a simple structure and is easy to assemble. A worker can use a normal tool to complete daily maintenance without the need for a professional workplace, professionals or special equipment.
