Description

dual cavity tire

technical field

The utility model relates to an automobile accessory, in particular to a double-cavity tire.

Background technique

At present, the car tires on the market generally use vacuum tires, and they are single-chamber tires. Once the tire pressure is too high or punctured by a hard object, it is easy to blow out. If the vehicle becomes smaller, the direction of movement changes suddenly, it is easy for the vehicle to overturn or collide with other vehicles, resulting in accidents and endangering the safety of the driver, other vehicles or pedestrians.

Utility model content

The technical problem to be solved by the utility model is to provide a double-cavity tire that will not cause the vehicle to deviate, overturn or collide with other vehicles due to a tire blowout.

In order to solve the above problems, the technical solution adopted by the utility model is: a double cavity tire, including a wheel hub and a tire matched with the wheel hub, the tire includes tread rubber, sidewall rubber, belt layer, ply, air The dense layer, the tread rubber and the sidewall rubber are integrated, located on the outer layer of the tire, the inner layer is the airtight layer, the cord layer is between the outer layer and the inner layer, and the belt layer is located between the tread rubber and the cord layer. There is a partitioned tire wall in the inner cavity. One end of the partitioned tire wall is integrated with the tire, and the other end is bifurcated to form two beads. The shape and structure of the two beads are the same as those on both sides of the tire. Two bead seats matching the tires are arranged in the center of the wheel hub, and the outer shape and structure of the bead seats are the same as those on both sides of the wheel hub.

Further, the belt layer is divided into left and right parts, bounded by the partition wall, and located between the tread rubber and the carcass layer on both sides of the partition wall.

Further, the partition tire wall includes an airtight layer, a carcass layer, and a partition rubber layer in sequence from both sides to the middle.

Further, a negative pressure suction hole is provided between the two bead seats in the middle of the hub, and a negative pressure suction device is installed in the hole.

The beneficial effects produced by adopting the above-mentioned technical scheme are:

The utility model divides the inner cavity of the tire into two parts by adding a partition in the middle of the tire. Even if one cavity is punctured or blows out when the vehicle is running at high speed, the other cavity can be tightly combined with the wheel hub. It will not fall off due to air leakage, and the vehicle can run normally as usual, and will not lose control due to air leakage or tire blowout, resulting in traffic accidents, ensuring the safety of the vehicle and drivers.

Detailed ways

Below in conjunction with accompanying drawing, utility model is described in further detail:

The utility model relates to a double-cavity automobile tire. The inner cavity of the tire is divided into two parts by an integral partition tire wall. Even if one cavity is punctured or punctured, the other cavity can still be used normally. The tire will not be deflated and detached from the hub, making the vehicle safer during driving.

As shown in Figure 1, the utility model comprises wheel hub 7 and the tire that matches with wheel hub 7, and described tire comprises tread rubber 1, sidewall rubber, belt layer 2, carcass ply 3, airtight layer 4, tread rubber 1 is integrated with the sidewall rubber, located on the outer layer of the tire, the inner layer is the airtight layer 4, the ply 3 is between the outer layer and the inner layer, and the belt layer 2 is located between the tread rubber 1 and the ply 3, There is a partitioned tire wall 8 in the inner cavity. One end of the partitioned tire wall 8 is integrated with the tire, and the other end is bifurcated to form two beads 9. The shape and structure are the same, and two bead seats 5 matching the tire are arranged in the middle of the wheel hub 7, and the shape and structure of the bead seats 5 are the same as those on both sides of the wheel hub.

In order to make the two cavities of the tire have a certain degree of independence, to ensure that when one cavity of the tire is punctured or blown out, the tire will not be separated from the hub, and the tire pressure of the partitioned tire wall can meet the needs of normal driving. The bundle layer 2 is divided into left and right parts, bounded by the partition wall 8, between the tread rubber and the ply on both sides of the partition wall 8, and the partition wall 8 is airtight from both sides to the middle. ply, ply, partition glue layer.

In order to facilitate the installation or disassembly of the tire and ensure that the tire does not break away from the wheel hub, a negative pressure suction hole is provided between the two bead seats 5 in the middle of the wheel hub, and a negative pressure suction device 6 is installed in the hole.
