Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a double-cavity tire. Background Art

[0002] With the development of society and the continuous advancement of science and technology, the functionality, comfort and practicality of automobiles are constantly improving. As an important part of road transportation, automobiles have become an indispensable part of people's travel and transportation. Automobiles have greatly facilitated people's lives, improved people's travel and transportation efficiency, greatly shortened spatial distances, and saved people's time costs.

[0003] In the history of automobile structure development, wheels have always been one of the basic elements of automobile structure. The wheels rotate under the drive of the transmission shaft, and the rolling friction between the wheels and the ground enables the car to move. In the process of gradual evolution of wheel structure, the structure of modern automobile wheels is mainly a combination of wheel hub and tire. The tire is set on the outside of the wheel hub, and the tire and the wheel hub are locked by inflating the tire.

[0004] Tires in the prior art usually have only one cavity. When a tire is damaged, the current tire cannot be used and the tire must be repaired or replaced in a timely manner to allow the car to continue to work normally. This undoubtedly affects the safety of the car and the components make the car more complicated. Therefore, in order to solve the related use risks caused by the tire having only one air cavity in the prior art, it is necessary to develop a tire with two independent air cavities. Utility Model Content

[0005] The utility model aims to provide a dual-cavity tire, in which two air cavities are relatively and parallelly fixed inside the outer tire by a connecting base layer through an outer tire with an outer curved surface, thereby two fixed air cavities are arranged inside the tire, and when any one of the tires is damaged, the use of the tire can be made more stable.

[0006] The purpose of the utility model is achieved by a dual-cavity tire, comprising:

[0007] A tire layer, wherein the outer side of the tire layer is a curved surface structure;

[0008] An air cavity, wherein two air cavities are arranged in parallel, and the tops of the two air cavities are fixedly arranged on the inner wall of the outer tire layer;

[0009] A connecting base layer, which is disposed between the outer tire layer and the tops of the two air cavities and is used for fixed connection between the two air cavities and the outer tire layer; and

[0010] The two air cavities are separated from each other in the width direction of the outer tire layer, and the opening ends of the two air cavities are arranged in the same direction. The cross section of the air cavity is an elliptical structure, and the opening end is provided with a tire lip steel wire group.

[0011] Furthermore, the connecting base layer includes a main base layer and a secondary base layer, the main base layer and the secondary base layer are integrally arranged, the main base layer is arranged between the top of the air cavity and the inner wall of the outer tire layer, and the secondary base layer is provided with connecting curved surfaces on both sides, and the connecting curved surfaces are closely arranged with the corresponding air cavity.

[0012] Furthermore, the tire lip steel wire group includes a first steel wire ring arranged on one side of the opening end and a second steel wire ring arranged on the other side of the opening end.

[0013] Furthermore, the thickness of the air cavity gradually becomes thinner from the two ends to the middle.

[0014] Furthermore, the air cavity comprises an inner wall and an outer wall, and the inner walls of the two air cavities are arranged adjacent to each other.

[0015] Furthermore, the length of the sub-base layer is one sixth of the length of the air cavity.

[0016] Furthermore, the open ends of the two air cavities are sealed and fixedly connected to the rim of a matching dual-cavity hub, and the rim includes a rim body and a rim group arranged on the outer side of the rim body, and the rim group includes two groups of rims, and each group of rims is provided with a valve tube.

[0017] Furthermore, the two groups of rims include a first rim and a second rim arranged in sequence in the width direction of the rim body, the first rim including a first outer rim fixedly set away from the spokes and a first inner rim arranged in the middle of the rim body; the second rim includes a second outer rim fixedly set close to the spokes and a second inner rim arranged in the middle of the rim body.

[0018] Furthermore, the second valve pipe of the second wheel rim is fixedly arranged in the second outer wheel rim, the air inlet end of the second valve pipe is placed outside the second outer wheel rim, and the pipe of the second valve pipe passes through the second outer wheel rim.

[0019] The beneficial effects of the utility model are embodied in:

[0020] 1. In the utility model, an outer tire layer with a curved surface structure is provided on the outer side, and two independent air cavities are fixedly provided therein, so that two air cavities are provided inside one outer tire layer. When one air cavity is damaged, the other air cavity can still support the automobile to a certain extent, thereby improving the stability of the automobile in operation. More specifically, due to the provision of a connecting base layer to fix the two independent air cavities in the outer tire layer, the ends where the two air cavities are connected to the outer tire layer are not only fixedly connected to the outer tire layer, but also one end of the two air cavities is connected and reinforced with a certain interval, so that the two air cavities can be stably and independently fixed inside the outer tire layer.

[0021] 2. In the utility model, since the connecting base layer is configured to be composed of a main base layer and a secondary base layer, and the main base layer and the secondary base layer are integrally configured, the main base layer is configured between the top of the air cavity and the inner wall of the outer tire layer, thereby achieving that the two air cavities are fixedly configured on the inner wall of the outer tire layer, while under the action of the secondary base layer, the two air cavities can be relatively spaced and fixedly configured in the outer tire layer, which can enhance the relative independence and certain stability of the two cavities configured in the outer tire layer, thereby improving the safety and stability of the entire double-cavity tire.

[0022] 3. In the utility model, since a tire lip wire group is arranged at the open end of the air cavity, the tight installation between the open end of the air cavity and the rim on the wheel hub is strengthened. More specifically, the tire lip wire group includes a first wire ring arranged on one side of the open end and a second wire ring arranged on the other side of the open end. Two annular edges are arranged at the open end of the air cavity, and the first wire ring and the second wire ring are respectively arranged on the corresponding edges, thereby strengthening the sealing of the close installation between the open end of the air cavity and the rim.

[0023] 4. In the utility model, the thickness of the air cavity is gradually thinned from the two ends to the middle, so that the two ends of the air cavity that mainly bear the force can have better strength. Therefore, under the premise of ensuring the working performance of the tire, the material is reduced as much as possible, and the weight and manufacturing cost of the tire are reduced.

[0024] 5. In the utility model, since the first wheel rim and the second wheel rim are arranged in the two groups of wheel rims, and the first wheel rim and the second wheel rim are arranged in sequence in the width direction of the rim body, the corresponding tires arranged in the width direction of the hub are subjected to uniform and balanced forces, thereby ensuring the stability of the working after the hub and the tire are matched; at the same time, relatively independent first wheel rim and second wheel rim are arranged to install the corresponding tires, making the installation of the tires more convenient and independent of each other without being affected.
