[0028] The following refers to Figure 1 - Figure 2Describe the wheel hub 100 according to an embodiment of the present utility model. By providing the rim 1, the installation of the tire 101 can be achieved. By providing a plurality of spokes 2, the support and fixation of the rim 1 can be realized, improving the reliability of the rim 1 during operation. And by providing a hollow cavity 21 in at least one spoke 2, the weight of the spoke 2 can be effectively reduced, thereby reducing the overall weight of the wheel hub 100, meeting the lightweight requirements of the vehicle, improving the endurance of the vehicle, and being beneficial to improving user satisfaction.

[0029] As Figure 1 shown, the wheel hub 100 according to an embodiment of the present utility model includes: a rim 1 and a plurality of spokes 2.

[0030] Specifically, the wheel hub 100 is an important component on the vehicle, which plays a role in connecting the tire 101 and the vehicle suspension system and can be used to support and transmit power. The rim 1 and the spokes 2 are provided in the wheel hub 100. Among them, the rim 1 is used to fix the tire 101 and can be used to absorb and disperse the impact and vibration during the vehicle's driving process to reduce the impact and vibration transmitted to the vehicle body and the passengers in the vehicle. The spokes 2 are used to connect the central part of the wheel hub 100 and the rim 1 to support and fix the rim 1 to ensure that the tire 101 can maintain stability during driving.

[0031] A plurality of spokes 2 are sequentially distributed along the circumferential direction of the wheel hub 100. The spokes 2 are configured to extend along the radial direction of the wheel hub 100. The rim 1 is connected to the outside of the plurality of spokes 2 and is configured to extend along the circumferential direction of the wheel hub 100 for installation and cooperation with the tire 101. At least one spoke 2 is provided with a hollow cavity 21.

[0032] Specifically, a plurality of spokes 2 are provided in the wheel hub 100, that is, the number of spokes 2 can be two, three or more. Further, the central part of the wheel hub 100 and the rim 1 can be connected simultaneously by the plurality of spokes 2, improving the connection reliability between the two, and enabling the plurality of spokes 2 to jointly support and fix the rim 1, improving the reliability of supporting and fixing the rim 1. And by sequentially distributing the plurality of spokes 2 along the circumferential direction of the wheel hub 100, the plurality of spokes 2 can be evenly distributed along the circumferential direction of the wheel hub 100 to improve the stability of supporting the rim 1. At the same time, the rim 1 is arranged on the periphery of the wheel hub 100 to facilitate the cooperation between the rim 1 and the tire 101 to achieve the installation of the tire 101. And by making the rim 1 extend along the circumferential direction of the wheel hub 100, the rim 1 can be a circle to adapt to the shape of the tire 101, that is, everywhere on the tire 101 can cooperate with the rim 1, thereby improving the reliability of the installation and cooperation between the rim 1 and the tire 101.

[0033] Moreover, the rim 1 is connected to the outer sides of a plurality of spokes 2. Even if the rim 1 can be simultaneously connected to the plurality of spokes 2 from the outer sides of the plurality of spokes 2, the rim 1 is connected to the central part of the hub 100 through the plurality of spokes 2 at the same time, so as to jointly support and fix the rim 1. And the spokes 2 are configured to extend radially along the hub 100, which can make the spokes 2 approach the central part of the hub 100 and the rim 1 at the same time, improving the reliability of supporting and fixing the rim 1 by the spokes 2. In addition, a hollow cavity 21 is arranged in the spoke 2, and the hollow cavity 21 can be used to reduce the weight of the spoke 2, and further can reduce the overall weight of the hub 100, meet the lightweight requirements of the vehicle, improve the endurance of the vehicle, and a hollow cavity 21 can be arranged in at least one spoke 2, that is, the number of spokes 2 provided with the hollow cavity 21 can be one, two or more, so as to further reduce the weight of the spoke 2, and effectively reduce the weight of the hub 100.

[0034] It should be noted that when the hollow cavities 21 are arranged in a plurality of spokes 2, the sizes and shapes of the plurality of hollow cavities 21 can be the same, and the plurality of hollow cavities 21 can be evenly distributed along the circumferential direction of the hub 100, so that the hub 100 can be balanced in force and the possibility of deformation and failure of the hub 100 can be reduced.

[0035] Thus, by arranging the rim 1, the installation of the tire 101 can be realized. By arranging the spokes 2, the support and fixation of the rim 1 can be realized. And the number of the spokes 2 is a plurality, so that the rim 1 can be jointly supported and fixed by the plurality of spokes 2, improving the reliability of the rim 1 in working. At the same time, the hollow cavity 21 is arranged in the spoke 2 to reduce the weight of the spoke 2, and by arranging the hollow cavity 21 in at least one spoke 2, the weight of the spoke 2 can be effectively reduced.

[0036] For the hub 100 according to the embodiment of the present utility model, by arranging the rim 1, the installation of the tire 101 can be realized. By arranging a plurality of spokes 2, the support and fixation of the rim 1 can be realized, improving the reliability of the rim 1 in working. And by arranging the hollow cavity 21 in at least one spoke 2, the weight of the spoke 2 can be effectively reduced, and further the overall weight of the hub 100 can be reduced, meeting the lightweight requirements of the vehicle, improving the endurance of the vehicle, and being beneficial to improving user satisfaction.

[0037] In some embodiments, the hollow cavity 21 is configured to have a strip-shaped cross-section, and the strip-shaped cross-section extends radially along the hub 100 and is arranged in the spoke 2.

[0038] Specifically, a hollow cavity 21 is provided inside the spoke 2. The hollow cavity 21 is used to reduce the weight of the spoke 2. By making the hollow cavity 21 have a strip-shaped cross-section, it can have a certain length, thereby increasing the occupied space of the hollow cavity 21 inside the spoke 2 to reduce the weight of the spoke 2. And by making the strip-shaped cross-section extend along the radial direction of the hub 100, the length of the strip-shaped cross-section can be made larger, further increasing the occupied space of the hollow cavity 21 inside the spoke 2 to effectively reduce the weight of the spoke 2.

[0039] In some embodiments, the strip-shaped cross-section is configured to extend in an arc shape, and the extending direction of the strip-shaped cross-section is the same as the extending direction of the spoke 2.

[0040] Specifically, as Figure 1 - Figure 2 shown, making the spoke 2 extend in an arc shape can reduce the air resistance during vehicle driving and improve the rotation efficiency of the wheel. At the same time, making the strip-shaped cross-section of the hollow cavity 21 also extend in an arc shape and making the extending direction of the strip-shaped cross-section the same as the extending direction of the spoke 2 is convenient for arranging the hollow cavity 21 inside the spoke 2, making the surface of the spoke 2 as smooth as possible to effectively reduce the air resistance during vehicle driving and improve the rotation efficiency of the wheel.

[0041] In some embodiments, the extending length of the strip-shaped cross-section is not less than half of the extending length of the spoke 2.

[0042] Specifically, a hollow cavity 21 is provided inside the spoke 2. The hollow cavity 21 is used to reduce the weight of the spoke 2. By making the extending length of the strip-shaped cross-section of the hollow cavity 21 not less than half of the extending length of the spoke 2, that is, the extending length of the strip-shaped cross-section can be 1 / 2, 2 / 3, or 3 / 4 of the extending length of the spoke 2, etc., thereby making the extending length of the hollow cavity 21 not less than half of the extending length of the spoke 2 to ensure the occupied space of the hollow cavity 21 inside the spoke 2 and effectively reduce the weight of the spoke 2.

[0043] It should be noted that the extending length of the hollow cavity 21 can be flexibly set on the premise of ensuring the stiffness of the spoke 2.

[0044] In some embodiments, the spoke 2 includes an inner end region 22, a middle region 23, and an outer end region 24 that are sequentially distributed along the radial direction of the hub 100.

[0045] Specifically, as Figure 1 - Figure 2As shown, the spoke 2 is used to connect the central part of the hub 100 and the rim 1. The spoke 2 includes an inner end region 22, a middle region 23, and an outer end region 24. That is, the connection between the central part of the hub 100 and the rim 1 can be achieved jointly by the inner end region 22, the middle region 23, and the outer end region 24, and the rim 1 can be supported jointly to improve the reliability of the rim 1 during operation. Moreover, the inner end region 22, the middle region 23, and the outer end region 24 are arranged in sequence along the radial direction of the hub 100. That is, the inner end region 22 and the outer end region 24 can be respectively connected to both ends of the middle region 23, and by connecting the inner end region 22 to the central part of the hub 100 and connecting the outer end region 24 to the rim 1, the connection between the central part of the hub 100 and the rim 1 is realized, and the support and fixation of the rim 1 are achieved, improving the reliability of the rim 1 during operation.

[0046] Among them, in the axial direction of the hub 100, the widths of both the inner end region 22 and the outer end region 24 are greater than the width of the middle region 23. The strip-shaped cross-section penetrates the middle region 23, and one end of the strip-shaped cross-section is located within the inner end region 22, and the other end of the strip-shaped cross-section is located within the outer end region 24.

[0047] Specifically, by arranging the inner end region 22, the middle region 23, and the outer end region 24 in sequence along the radial direction of the hub 100, the inner end region 22 and the outer end region 24 can be respectively arranged at both ends of the middle region 23 to connect the inner end region 22 and the outer end region 24 to the central part of the hub 100 and the rim 1 respectively. Moreover, in the axial direction of the hub 100, the widths of both the inner end region 22 and the outer end region 24 are greater than the width of the middle region 23, which can increase the connection area between the inner end region 22 and the central part of the hub 100 and the connection area between the outer end region 24 and the rim 1. Furthermore, the connection strength between the spoke 2 and the central part of the hub 100 and the rim 1 can be increased, improving the reliability of using the spoke 2 to connect the central part of the hub 100 and the rim 1, and the reliability of the spoke 2 to support the rim 1 can be improved. Consequently, the reliability of the rim 1 during operation can be enhanced.

[0048] In addition, by making the strip-shaped cross-section penetrate the middle region 23 and one end be located within the inner end region 22 and the other end be located within the outer end region 24, the strip-shaped cross-section can penetrate the inner end region 22 through the middle region 23 and extend into the outer end region 24, so as to increase the set length of the hollow cavity 21, increase the occupied space of the hollow cavity 21 within the spoke 2, effectively reduce the weight of the spoke 2, and further reduce the overall weight of the hub 100.

[0049] In some embodiments, the width of the hollow cavity 21 in the axial direction of the hub 100 is less than 1 / 3 of the width of the spoke 2 in the axial direction of the hub 100.

[0050] Specifically, a hollow cavity 21 is provided inside the spoke 2. The hollow cavity 21 is used to reduce the weight of the spoke 2. The width of the hollow cavity 21 in the axial direction of the hub 100 is less than 1 / 3 of the width of the spoke 2 in the axial direction of the hub 100. That is, the width of the hollow cavity 21 in the axial direction of the hub 100 can be 1 / 4, 1 / 5, 1 / 6, etc. of the width of the spoke 2 in the axial direction of the hub 100, so as to ensure the width of the portions of the spoke 2 on both sides of the hollow cavity 21, that is, to ensure the strength of the portions of the spoke 2 on both sides of the hollow cavity 21, and to avoid the situation that due to the too large width of the hollow cavity 21, the width of the portions of the spoke 2 on both sides of the hollow cavity 21 is too small, resulting in a reduction in the strength of the spoke 2, that is, reducing the lateral stiffness of the hub 100, and further causing the hub 100 to be easily deformed and fail.

[0051] It should be noted that, on the premise of ensuring the strength of the portions of the spoke 2 on both sides of the hollow cavity 21, the width of the hollow cavity 21 in the axial direction of the hub 100 can be made as large as possible to effectively reduce the weight of the spoke 2.

[0052] In some embodiments, each spoke 2 is provided with a plurality of hollow cavities 21, and the plurality of hollow cavities 21 are spaced apart and distributed on the spoke 2.

[0053] Specifically, a hollow cavity 21 is provided inside the spoke 2. The hollow cavity 21 is used to reduce the weight of the spoke 2. The hollow cavity 21 can be provided on each spoke 2, that is, the number of hollow cavities 21 can be increased, and the weight of the corresponding spoke 2 can be reduced by each hollow cavity 21. Furthermore, the overall weight of the hub 100 can be reduced. Moreover, a plurality of hollow cavities 21 can also be provided on each spoke 2, that is, the number of hollow cavities 21 provided on each spoke 2 can be two, three or more, so as to jointly reduce the weight of the corresponding spoke 2 through the plurality of hollow cavities 21. Furthermore, the overall weight of the hub 100 can be effectively reduced. And by spacing the plurality of hollow cavities 21 apart and distributing them on the spoke 2, it is possible to avoid a significant reduction in the strength of the spoke 2 at the position where the hollow cavity 21 is located, and to prevent the hub 100 from being easily deformed and failing.

[0054] In some other embodiments, the plurality of spokes 2 are respectively a plurality of first spokes and a plurality of second spokes. The first spokes are provided with hollow cavities 21, and the second spokes are not provided with hollow cavities 21. The plurality of first spokes and the plurality of second spokes are alternately distributed in the circumferential direction of the hub 100.

[0055] Specifically, a plurality of first spokes and a plurality of second spokes can be provided in the plurality of spokes 2. That is, the number of spokes 2 can be increased by the plurality of first spokes and the plurality of second spokes to improve the reliability of supporting and fixing the rim 1. Moreover, a hollow cavity 21 can be provided on the first spoke to reduce the weight of the spoke 2. At the same time, no hollow cavity 21 is provided on the second spoke, so that the structural strength of the second spoke can be relatively high to improve the reliability of supporting the rim 1. The plurality of first spokes and the plurality of second spokes are alternately distributed in the circumferential direction of the hub 100, so that the number of the first spokes is the same as that of the second spokes. Also, the plurality of first spokes can be spaced apart from each other, and the plurality of second spokes can be spaced apart from each other to prevent the local stiffness of the hub 100 from being poor and making the hub 100 prone to deformation.

[0056] Exemplarily, if a total of six spokes are provided on the hub 100, the number of the first spokes and the second spokes can be three respectively. The three first spokes and the three second spokes can be alternately distributed in the circumferential direction of the hub 100, that is, the three first spokes and the three second spokes can be evenly distributed in the circumferential direction of the hub 100. Also, the three first spokes can be spaced apart from each other, and the three second spokes can be spaced apart from each other to prevent the local stiffness of the hub 100 from being low and making the hub prone to deformation.

[0057] In some embodiments, a hollow cavity 21 is provided in each of the plurality of spokes 2, and the hollow cavities 21 of the plurality of spokes 2 are distributed opposite to each other in the circumferential direction of the hub 100.

[0058] Specifically, a hollow cavity 21 is provided inside the spoke 2. The hollow cavity 21 is used to reduce the weight of the spoke 2. A plurality of spokes 2 are provided in the hub 100, and the number of the hollow cavities 21 is also plural. The plurality of hollow cavities 21 can be respectively provided in the plurality of spokes 2 to space apart the plurality of hollow cavities 21 and prevent the lateral stiffness of the hub 100 from being significantly reduced, making the hub 100 prone to deformation and failure. At the same time, the hollow cavities 21 of the plurality of spokes 2 are distributed opposite to each other in the circumferential direction of the hub 100. That is, for each hollow cavity 21, there is another hollow cavity 21 opposite to it in the circumferential direction of the hub 100, and the distance from each hollow cavity 21 to the center of the hub 100 is equal, so that the hub 100 can be in force balance and reduce the possibility of deformation and failure of the hub 100 under the action of external forces.

[0059] In some embodiments, the rim 1 and the spokes 2 are integrally formed by casting, and the hollow cavity 21 is integrally formed in the spoke 2 by casting.

[0060] Specifically, the rim 1 and the spoke 2 can be integrally formed by casting, that is, the two can be directly constructed as a whole by casting, so as to reduce the assembly steps, reduce the labor and production costs, and the hollow cavity 21 is integrally formed in the spoke 2 to reduce the weight of the spoke 2, and further reduce the overall weight of the wheel hub 100, meet the lightweight requirements of the vehicle, and improve the endurance of the vehicle.

[0061] It should be noted that both the rim 1 and the spoke 2 can be integrally formed by casting aluminum. Because the damping characteristics of aluminum are good, it helps to reduce the transmission of vibration and noise, and thus is beneficial to the NVH performance of the vehicle.

[0062] The present utility model also provides a vehicle.

[0063] The vehicle according to the embodiment of the present utility model includes a tire 101 and the wheel hub 100 described above. The tire 101 is sleeved outside the rim 1. The tire 101 is used to cooperate with the rim 1 in the wheel hub 100 to realize the installation on the vehicle, and a plurality of spokes 2 are arranged in the wheel hub 100 to support and fix the rim 1, improve the reliability of the rim 1 during operation, and by arranging a hollow cavity 21 in at least one spoke 2, the weight of the spoke 2 can be effectively reduced, and further the overall weight of the wheel hub 100 can be reduced, meet the lightweight requirements of the vehicle, improve the endurance of the vehicle, and be beneficial to improving user satisfaction.
