Its performance directly affects the vehicle's driving safety, handling stability, and ride comfort.

[0003] When a car is driven in the rain, cement from the road surface can easily get into the inside of the wheel rim. After drying, it leaves mud spots inside the wheel rim. There are many hard-to-clean areas inside the wheel rim, making cleaning difficult and requiring improvement. Summary of the Invention:

[0004] The purpose of this invention is to provide a wheel hub to solve the problems mentioned in the background art.

The heat dissipation vent is located on the moving path of the water baffle. A driving component is provided on the protective assembly, and the driving component drives the water baffle to move and cover the heat dissipation vent.

[0007] Preferably, the hub body includes a hub shaft, spokes, and a rim. The spokes are located on opposite sides of the hub shaft. The heat dissipation vents are opened on the spokes. The hub shaft is provided with a plurality of spokes, which are spaced apart around the outer periphery of the hub shaft. The spokes connect the hub shaft and the rim. The spokes are detachably connected to the hub shaft. The water baffle is rotatably connected to the spokes. The driving component is disposed on the spokes.

Detailed implementation method:

[0022] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —3:

[0023] This application discloses a wheel hub. See also: A wheel hub... Figure 1 and Figure 2 The wheel includes a hub body 1, which includes a hub axle 11, spokes 12, and a rim 13. The hub axle 11 and the rim 13 are spaced apart. The hub axle 11 is located inside the rim 13. The cross-section of the hub axle 11 has the same center as the cross-section of the rim 13. There are two spokes 12, and the distribution direction of the two spokes 12 is parallel to the axis of the hub axle 11. The spokes 12 cover the opposite ends of the rim 13. The spokes 12 are detachably connected to the rim 13. Several spokes 14 are fixed on the hub axle 11. The spokes 14 are evenly distributed around the outer circumference of the hub axle 11. The spokes 14 are located between the hub axle 11 and the rim 13. The opposite ends of the spokes 14 are fixedly connected to the hub axle 11 and the rim 13, respectively. The rim 13 and the hub axle 11 are fixed by the spokes 14. The spoke 12 is detachably connected to the rim 13. The spoke 12 is detachably connected to the hub shaft 11 through the fit between the rim 13, the spokes 14 and the hub shaft 11. When the spoke 12 is fixed to the rim 13, the spokes 14 and the spoke 12 together support the rim 13, which helps to improve the compressive strength of the hub.

[0024] See Figure 1 and Figure 2 A plurality of connecting pieces 121 are fixed on the spoke 12. The connecting pieces 121 are evenly spaced around the outer circumference of the spoke 12 and are located on the side of the spoke 12 away from the hub shaft 11. The outer ring of the spoke 12 fits against the inner ring of the rim 13. A positioning bolt is passed through the connecting piece 121. The axis of the positioning bolt is perpendicular to the axis of the rim 13. The positioning screw passes through the connecting piece 121 and is threadedly connected to the rim 13. After the spoke 12 is fixed to the rim 13 by the positioning screw, the spoke 12 and the hub shaft 11 are spaced apart. The positioning bolt is not shown in this embodiment.

[0025] See Figure 1 and Figure 2 The hub shaft 11 has a shaft hole 111 for the axle to pass through and connect. By setting the spokes 12 and hub shaft 11 at intervals, it is easy to leave the space required for installing the axle.

[0026] When the spoke 12 is damaged, the locating screw can be removed by rotating it, and a new spoke 12 can be installed without replacing the entire wheel hub, which helps to reduce the maintenance cost of the wheel hub.

[0027] See Figure 2 and Figure 3The spoke 12 has a plurality of heat dissipation holes 122, which are spaced around the outer periphery of the hub shaft 11. The heat dissipation holes 122 are connected to the inside of the rim 13. In this embodiment, the number of heat dissipation holes 122 on each spoke 12 is 4. A baffle plate 2 is rotatably connected to the side of the spoke 12 near the hub shaft 11. The baffle plate 2 includes a connecting part 21 and several baffle plates 22. The connecting part 21 is rotatably connected to the spoke 12, and the axis of rotation of the connecting part 21 is on the same straight line as the axis of the hub shaft 11. The connecting part 21 is annular and is arranged around the outer periphery of the hub shaft 11. The position and number of baffle plates 22 correspond one-to-one with the position and number of heat dissipation vents 122 on the corresponding spoke 12. Several baffle plates 22 are evenly distributed around the outer periphery of the connecting part 21, and several heat dissipation vents 122 are arranged around the outer periphery of the connecting part 21. The heat dissipation vents 122 are located on the rotation path of the corresponding baffle plates 22. The rotation of the connecting part 21 drives the baffle plates 22 to move and close or open the corresponding heat dissipation vents 122. A driving member 3 is fixed on the spoke 12, and the driving member 3 drives the connecting part 21 to rotate.

[0028] See Figure 2 and Figure 3 A positioning ring 23 is fixed on the side of the connecting part 21 near the hub shaft 11. The positioning ring 23 is arranged around the outer periphery of the hub shaft 11. The inner wall of the positioning ring 23 fits against the outer wall of the hub shaft 11, which facilitates the positioning of the spoke 12 and helps to improve the connection stability between the spoke 12 and the hub shaft 11.

[0029] See Figure 2 and Figure 3 The driving component 3 is an electric telescopic rod 31, which is located in the gap between the hub shaft 11 and the spoke 12. The electric telescopic rod 31 is located inside the connecting part 21, and its projection in the direction parallel to the rotation axis of the connecting part 21 is located on the hub shaft 11. An abutment part 211 is integrally formed on the connecting part 21, located in the inner ring of the connecting part 21. The electric telescopic rod 31 is movably connected to the abutment part 211. The extension and retraction of the electric telescopic rod 31 drives the water baffle 2 to rotate and close or open the corresponding heat dissipation port 122.

[0030] The drive component 3 is located close to the rotation axis of the baffle plate 2, which helps to reduce the required stroke of the drive component 3 and reduce the size of the drive component 3.

[0031] See Figure 2 and Figure 3 Each baffle plate 22 is fixed with a limiting strip 221. The limiting strip 221 is located on the side of the baffle plate 2 away from the hub shaft 11. The position and number of the limiting strips 221 correspond one-to-one with the position and number of the heat dissipation vents 122. The limiting strip 221 is inserted into the corresponding heat dissipation vent 122. The end of the limiting strip 221 away from the hub shaft 11 protrudes out of the limiting strip 221 and abuts against the inner wall of the heat dissipation vent 122 for limiting.

[0032] When the car is driving in the rain, the drive unit 3 drives the baffle 2 to rotate and close the heat dissipation vent 122, reducing the amount of cement entering the wheel hub through the heat dissipation vent 122. When the car is driving in high temperatures, the drive unit 3 drives the baffle 2 to open the heat dissipation vent 122, improving the heat dissipation efficiency of the wheel hub. During the opening of the baffle 2, the spokes 12, which are in contact with the baffle 2, scrape away dirt from the surface of the baffle 2.

[0033] The implementation principle of a wheel hub in this application embodiment is as follows: by setting a baffle plate 2 on the wheel hub body 1 to cover the heat dissipation port 122, the splashed cement is not easy to enter the dead corner inside the wheel hub. During the cleaning process, the surface of the wheel hub and the baffle plate 2 can be cleaned, which helps to reduce the cleaning difficulty.

[0034] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
