Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0024] The utility model discloses a low-noise wheel hub which is mainly used in the scene of the wheel hub of an electric scooter.

[0025] Reference Figures 1 to 5 A low-noise wheel hub comprises: a wheel hub body 1, an inner ring rim 8 is fixedly connected inside the wheel hub body 1, a spoke support frame 3 is equidistantly fixedly connected to the outer side of the inner ring rim 8, one end of the spoke support frame 3 is fixedly connected to a mounting shaft block 6, a brake device 4 is arranged on one side of the mounting shaft block 6, bolts 7 are equidistantly threadedly connected between one side of the brake device 4 and one side of the mounting shaft block 6, an annular reinforcing rib 9 is arranged on the outer side of the wheel hub body 1, a tire 2 is arranged on the outer side of the wheel hub body 1, a pattern 5 is arranged on the outer side of the tire 2, and a first covering layer 10 is arranged on the outer side of the tire 2.

[0026] In the above technical scheme, considering the problem that the existing electric scooter wheel hub is not strong enough and is easy to wear, in order to solve such problems, the specific operations are as follows: by setting a first covering layer 10 on the outer side of the tire 2, the wear resistance of the overall wheel hub can be improved, the service life can be extended, wear and damage can be reduced, and the tire 2 can be effectively prevented from being affected by ultraviolet rays and oxidation, thereby extending the service life of the tire 2.

[0027] Reference Figure 5In a preferred embodiment, a second covering layer 11 is disposed on the outer side of the first covering layer 10, and the second covering layer 11 is coated with rubber, and a third covering layer 12 is disposed on the outer side of the second covering layer 11, and both the first covering layer 10 and the third covering layer 12 are coated with polyurethane;

[0028] In the above technical solution, considering that the existing electric scooter wheel hub is not strong enough and generates a lot of noise during driving, in order to solve such problems, the specific operation is as follows: by setting the second covering layer 11, adding a rubber coating to the outer layer of the tire 2 can reduce the noise generated during driving. Rubber has a certain sound absorption and shock absorption effect, which can effectively reduce the noise generated by the friction between the vehicle and the ground when driving, and improve driving comfort. By setting the first covering layer 10, the second covering layer 11 and the third covering layer 12, not only can the strength of the overall wheel hub be enhanced, but also it can have better wear resistance and reduce noise.

[0029] Reference Figure 1 and Figure 3 In a preferred embodiment, the exterior of the bolts 7 are coated with anti-corrosion paint;

[0030] Working principle: When in use, by setting the second covering layer 11, adding a rubber coating to the outer layer of the tire 2 can reduce the noise generated during driving. Rubber has certain sound absorption and shock absorption effects, which can effectively reduce the noise generated by the friction between the vehicle and the ground when driving, and improve driving comfort. By setting the first covering layer 10, the second covering layer 11 and the third covering layer 12, not only the strength of the overall wheel hub can be enhanced, but also it can have better wear resistance and reduce noise. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0031] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
