Abstract

The present invention provides a low-wind-resistance heat-dissipation hub, which comprises: a hub, wherein the interior of the hub is a sealed space, or the speed at which air flows into the interior of the hub from one side surface is directly proportional to the degree to which the other side surface seals the interior of the hub; and a rotating piece assembly, wherein the rotating piece assembly is concentrically connected to the hub.

It can also work in conjunction with the clutch device 5.

[0049] The working principle of the low wind resistance heat dissipation hub and vehicle of the application described in the above embodiments is as follows:

[0050] During high-speed driving of the vehicle, the pieces of the object 2 formed by connecting a plurality of pieces around the center of a columnar body rotate at high speed in the hub. The face in the direction of rotation of the pieces, i.e., the front face, compresses air, and the back face generates a vacuum area. The volume of air in the hub becomes smaller, and the inside of the hub is a closed or dynamically sealed space. The air fills the space, and the atmospheric pressure outside the hub causes the air to enter the inside of the hub from the opening side of the hub, to be compressed and centrifuged, to reach the inner wall of the hub to continue to be compressed, oriented, and expanded, and then to rotate out of the opening side of the hub according to the structure of the hub. Compared with the existing low wind resistance hub, the air on both sides of the hub is not communicated or is dynamically sealed according to the viscosity and viscosity resistance of the air. The high-speed airflow quickly flows through the surface on the other side of the hub, thereby achieving low wind resistance and significantly improving the heat dissipation performance. The hub can produce heat dissipation in both forward and reverse rotation.

[0051] Regarding the dynamic sealing, taking a bicycle in daily life as an example, if the tire is punctured, if it is a very small hole, the air leaks slowly, although it is not a sealed space, it can still maintain the pressure for a period of time, at this time, dynamic sealing is formed. A large hole, or a crack, cannot form dynamic sealing, and the tire quickly deflates. The difference is that the tire in the bicycle has a fixed air pressure, and the dynamic sealing pressure will gradually decrease, while the present application continuously compresses the air in the pieces, and the pressure is always maintained. If there is a small independent hole on the outer surface of the hub, the air has viscosity, viscosity resistance, and the centrifugal motion of the air on the outer surface of the hub due to the viscous force, as well as inertia, all affect the speed of air entering and exiting from the small hole, thereby maintaining the dynamic closed state of the inside of the hub. The air mainly enters the inside of the hub from the middle of the inner side, and then rotates out of the hub according to the structure of the final product of the hub. The closer the inside of the hub is to the closed state, the greater the negative pressure generated, and the faster the speed of air flowing into the inside of the hub from the inner side. The low wind resistance hub can reserve a small hole for the tire inflation pipeline, or the combination of the hub cover and the hub can have a small gap, which can achieve dynamic sealing according to the viscosity resistance.

[0052] Due to the above structure, the low wind resistance heat dissipation hub of the application can achieve the following effects compared with the prior art:

[0053] The application is according to the characteristics of air, air has mass and inertia, centrifugal force is generated when rotating, air is easy to be compressed, air can fill the space, air has viscosity, when the sheet rotates, the front of the sheet compresses the air in the centrifugal wheel hub, the back of the sheet is quickly filled with air due to atmospheric pressure, thereby forming a very high air flow rate, the air flows through the surface of the brake device to take away the heat of the brake, the outer side of the wheel hub is a whole surface, lower wind resistance can be obtained, in another scheme of the application, the brake device does not work all the time during the driving of the vehicle, the brake device can be cooled after braking, the brake device stops working when the temperature of the brake device is normal, the outer side of the wheel hub is a whole surface, the favorite pattern can be randomly made, the application is intelligent, environment-friendly, energy-saving, emission-reducing and the endurance is increased.

[0054] The above implementation of the present application is only an example for clearly illustrating the present application, and is not a limitation on the implementation of the present application. Those skilled in the art can make various obvious changes, readjustments and substitutions without departing from the protection scope of the present application. It is not necessary and impossible to enumerate all the implementations. Any modification, equivalent substitution and improvement within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
