[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to solve the problem that after the steel wheels used on M1 vehicles in the prior art are installed with tire pressure monitoring devices, the overall structural balance is unbalanced, resulting in an increase in the imbalance of the steel wheels, which in turn easily causes shaking or vibration during driving of the passenger car, affecting the driving comfort of the passenger car, the present invention provides a steel wheel and a vehicle, wherein the vehicle includes the above-mentioned and hereinafter described steel wheels; it should be noted that the vehicle referred to in the present application is preferably a passenger car of M1 vehicle.

[0035] In the present application, the steel wheel includes a rim 10, a valve, a tire pressure monitoring device and a spoke 20. The rim 10 is provided with a valve hole 12, the valve is arranged at the valve hole 12, the tire pressure monitoring device is connected to the valve, the spoke 20 is connected to the rim 10 and is located inside the rim 10, and a center of gravity balancing part is formed on the spoke 20, which is used to balance the center of gravity deviation of the steel wheel caused by the valve and / or the tire pressure monitoring device being located on one side of the axis of the rim 10.

[0036] By optimizing the structure of the spoke 20, that is, a gravity center balancing part is formed on the spoke 20, and the gravity center balancing part is used to balance the gravity center deviation of the steel wheel caused by the valve and / or tire pressure monitoring device being located on one side of the axis of the rim 10. In other words, the gravity center balancing part can balance the gravity center of the entire steel wheel to the axis of the rim 10, thereby greatly reducing the imbalance of the steel wheel when rotating, and then effectively reducing the shaking or vibration of the vehicle during driving, and improving the driving comfort of the vehicle.

[0037] It should be noted that the valve hole 12 in the present application is formed on the side of the bottom groove of the rim 10 located on the inner side of the wheel flange 11 by a punching process.

[0038] Embodiment 1

[0039] like Figure 1 and Figure 2As shown, in this embodiment, the spoke 20 is provided with a plurality of air holes 21, which are arranged at intervals in the circumferential direction around the spoke 20 along a circle, wherein a weighted area 22 is formed at a position of one end of the spoke 20 away from the valve hole 12 and a diameter corresponding to the valve hole 12, and the air holes 21 are located outside the weighted area 22, so that the weight of the spoke 20 at the weighted area 22 is greater than the weight of the spoke 20 at a position adjacent to the valve hole 12, and a center of gravity balancing portion is formed at the weighted area 22. The arrangement of the plurality of air holes 21 can not only greatly reduce the overall weight of the wheel, but also improve the heat dissipation effect of the wheel; Figure 2 In the figure, the area surrounded by the dotted line is the counterweight area 22, and the counterweight area 22 is the solid part of the spoke 20. Since the counterweight area 22 is formed at a position away from the valve hole 12 on a diameter of the spoke 20 corresponding to the valve hole 12, the weight of the spoke 20 on a diameter corresponding to the valve hole 12 can be balanced at the center of the spoke 20, thereby making the center of gravity of the entire steel wheel balanced to the axis of the rim 10.

[0040] It should be explained that a diameter of the spoke 20 corresponding to the valve hole 12 , that is, an extension line of the diameter passes through the center of the valve hole 12 .

[0041] It should be noted that the intervals between two adjacent air holes 21 in all the air holes 21 are equal. Arranging multiple air holes 21 in this way is more conducive to balancing the weight of the spoke 20 at the center.

[0042] Embodiment 2

[0043] like Figure 3 and Figure 4 As shown, the difference between this embodiment and the first embodiment is that the wheel spoke 20 is further provided with at least one counterweight hole 23, which is located in the counterweight area 22, and the diameter of the counterweight hole 23 is smaller than the diameter of the air hole 21, and at least one counterweight hole 23 forms a center of gravity balancing portion. In this way, by adjusting the diameter of the counterweight hole 23, the weight of the wheel spoke 20 in the counterweight area 22 can be adjusted, so as to more effectively balance the weight of the valve stem and / or the tire pressure monitoring device at the valve hole 12, and greatly reduce the imbalance of the steel wheel. In addition, the counterweight hole 23 can also be used as a ventilation hole to facilitate heat dissipation of the steel wheel.

[0044] In order to improve the aesthetic appearance of the steel wheel and reduce the processing and manufacturing process of the steel wheel, optionally, all the air holes 21 and all the counterweight holes 23 are arranged at intervals along the circumference of the spoke 20 along the same circle.

[0045] In this embodiment, there is only one counterweight hole 23 , and the counterweight hole 23 and the valve hole 12 are arranged corresponding to the same diameter of the spoke 20 .

[0046] Embodiment 3

[0047] like Figure 5 and Figure 6 As shown, the difference between this embodiment and the first embodiment is that the wheel spoke 20 is provided with air holes 21 and counterweight holes 23, there are multiple air holes 21, there is at least one counterweight hole 23, all the air holes 21 are arranged at intervals along a circle around the wheel spoke 20 in the circumferential direction, the counterweight hole 23 is located at a position close to one end of the valve hole 12 of a diameter of the wheel spoke 20 corresponding to the valve hole 12, and the counterweight hole 23 is located at the circumferential outer side of the multiple air holes 21, and at least one counterweight hole 23 forms a center of gravity balancing part. In this way, by optimizing the opening position of the counterweight hole 23, the weight of the wheel spoke 20 near the valve hole 12 is reduced while ensuring that the steel wheel has sufficient ventilation, and it also plays a role in balancing the weight of the valve nozzle and / or tire pressure monitoring device at the valve hole 12, thereby reducing the imbalance of the steel wheel.

[0048] Optionally, there are a plurality of counterweight holes 23 , and the plurality of counterweight holes 23 are arranged at intervals along another circle around the circumference of the spoke 20 .

[0049] Optionally, the diameter of the counterweight hole 23 is greater than or equal to the diameter of the air hole 21. In this way, it is beneficial to accurately balance the weight of the valve stem and / or the tire pressure monitoring device by adjusting the diameter of the counterweight hole 23.

[0050] Embodiment 5

[0051] like Figures 7 to 9 As shown, a counterweight notch 24 is formed on the circumference of the spoke 20. When the spoke 20 is assembled on the rim 10, the counterweight notch 24 corresponds to the position of the valve hole 12, and the counterweight notch 24 forms a center of gravity balancing portion. In this way, the counterweight notch 24 can not only reduce the weight of the spoke 20, but also accurately reduce the weight of the assembled spoke 20 and the rim 10 at the valve hole 12, which is conducive to balancing the weight of the valve and / or tire pressure monitoring device at the valve hole 12, and reducing the imbalance of the steel wheel.

[0052] It should be explained that the counterweight notch 24 corresponds to the position of the valve hole 12 , that is, after the spoke 20 is mounted on the rim 10 , the counterweight notch 24 is located adjacent to the valve hole 12 .

[0053] It should be noted that the technical solution of this embodiment can be superimposed on the technical solution in any one of embodiments one to three, that is, the technical solution in this embodiment can be implemented on the technical solution in any one of embodiments one to three. Of course, the technical solution in this embodiment can also be implemented alone.

[0054] Embodiment 4

[0055] like Figures 10 to 12 As shown, the difference between this embodiment and the fourth embodiment is that a plurality of weight-reducing notches 25 are formed on the spoke 20, and the plurality of weight-reducing notches 25 and the counterweight notches 24 are arranged at intervals around the circumference of the spoke 20, wherein the opening area of ​​the counterweight notches 24 is larger than the opening area of ​​the weight-reducing notches 25. The weight-reducing notches 25 are conducive to reducing the overall weight of the spoke 20, and are more conducive to reducing the imbalance of the wheel in combination with the counterweight notches 24.
