Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of motorcycle inner tube, concretely to a light weight motorcycle inner tube structure. BACKGROUND

[0002] In the current motorcycle industry, the trend of light weight is more and more obvious, and the traditional light weight motorcycle inner tube often reduces the overall thickness of the inner tube in order to achieve the goal of reducing the overall weight.

[0003] However, this approach exposes many problems in actual use. During the riding process of the motorcycle, the inner tube is in a complex state. When riding for a long time, the tire continuously rubs against the ground, especially in the case of high-speed driving or frequent braking and starting, the friction generates more heat, causing the temperature of the environment in which the inner tube is located to rise sharply. The rubber material of the inner tube with a relatively thin thickness is easily affected by the high-temperature environment due to its limited heat capacity. The rubber may accelerate aging and become brittle, and the tear resistance is greatly reduced. Once the inner tube cracks, it is easy to cause air leakage, thereby shortening the service life of the inner tube. Therefore, there is an urgent need for a light weight motorcycle inner tube structure to solve the above problems. SUMMARY

[0004] The utility model aims at providing a light weight motorcycle inner tube structure to solve the problem of the traditional light weight motorcycle inner tube reducing the overall thickness in order to reduce the overall weight, which affects the service life of the inner tube under the influence of high temperature when the inner tube with a relatively thin thickness is ridden for a long time.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a light weight motorcycle inner tube structure, comprising a main inner tube, a secondary inner tube is arranged inside the main inner tube, the size of the secondary inner tube is smaller than that of the main inner tube, and silicon oil is arranged between the main inner tube and the secondary inner tube.

[0006] Preferably, the same connecting pipe is fixedly connected between the main inner tube and the secondary inner tube, and a plurality of branch holes are formed in the upper end of the connecting pipe.

[0007] Preferably, a threaded cap is threadedly connected to the surface of the connecting pipe, and the inner top surface of the threaded cap abuts against the upper end of the connecting pipe.

[0008] Preferably, a plurality of arc-shaped grooves are formed in the surface of the main inner tube, and the sizes of the arc-shaped grooves are matched.

[0009] Preferably, the main inner tube is made of nitrile rubber material, and the secondary inner tube is made of polyimide rubber material.

[0010] Preferably, the arc-shaped grooves are arranged on both sides of the main inner tube, and the sizes of the arc-shaped grooves are 0.3mm

[0011] Compared with the prior art, the utility model discloses the beneficial effects are:

[0012] Through the mutual cooperation of the primary inner tube, the secondary inner tube and the silicon oil, when the motorcycle is running, the primary inner tube and the secondary inner tube will deform and vibrate, so that the silicon oil between the two layers of inner tubes generates a small flow to form a convection, the silicon oil can bring heat from the area with higher temperature to the area with lower temperature, accelerates the heat transfer and dissipation, thereby increasing the service life of the primary inner tube and the secondary inner tube, and the silicon oil has extremely low surface tension and friction coefficient, when the silicon oil is filled between the primary inner tube and the secondary inner tube, the uniform oil film can be formed between the two layers of inner tubes, thereby effectively reducing the friction, reducing the heat and wear of the inner tube due to the friction, and further prolonging the service life of the inner tube.
