[0002] In the traditional rubber inner tube design, the inner tube is usually composed of a single rubber layer. Although this design is simple, it is easy to break or tear when subjected to high pressure or impact by sharp objects, resulting in the failure of the inner tube. In addition, the wear resistance of the inner tube is often insufficient, which affects its service life. Utility Model Content

[0005] The inner layer is provided with a gas nozzle connecting layer, the gas nozzle connecting layer is connected to the gas nozzle, the gas nozzle passes through the gas nozzle through hole opened on the wheel hub, and the wheel hub and the inner layer are fixedly connected.

[0006] As a further limitation of the present technical solution, the bearing is fixedly connected to the hub via a group of evenly arranged spokes.

[0007] As a further limitation of the present technical solution, the outer surface of the outer layer is provided with evenly arranged textures.

[0008] As a further limitation of the present technical solution, the outer surfaces of the outer layer and the reinforcement layer are coated with a protective layer to improve wear resistance and tear resistance.

[0009] As a further limitation of the present technical solution, the inner layer is a soft and highly elastic rubber material, and the outer layer is a highly tear-resistant rubber material.

[0010] As a further limitation of the present technical solution, the reinforcement layer is a steel wire woven mesh, and the reinforcement layer is arranged between the inner layer and the outer layer and is fixedly connected by hot pressing.

[0011] As a further limitation of the present technical solution, the air nozzle connecting layer and the inner layer are bonded by heat pressing, and the air nozzle connecting layer and the outer layer are adhesively connected.

[0012] As a further limitation of the technical solution, a rubber material is injected around the air nozzle connecting layer to form a reinforcement layer, and the reinforcement layer is attached to the surface of the inner layer.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] By arranging a reinforcement layer outside the inner layer, especially using a steel wire braided mesh as the reinforcement layer, the tear resistance of the inner tube is significantly improved;

[0015] The outer surface of the outer layer and the reinforcement layer is coated with a protective layer, which not only enhances the wear resistance, but also helps to protect the inner tube from erosion by the external environment;

[0016] The connection between the valve connecting layer on the inner side of the inner layer and the valve, as well as the fixed connection between the wheel hub and the inner layer, ensure the structural stability of the inner tube during use. The design of the valve connecting layer and the connection method with the valve help to improve the air tightness of the inner tube and reduce gas leakage. The evenly arranged texture on the outer layer surface increases the friction between the inner tube and the road and improves the grip. BRIEF DESCRIPTION OF THE DRAWINGS
