[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] A wheel rim is a cylindrical metal component mounted on an axle, supporting the tire within the tire's inner contour. Currently, most wheel rims on the market are made of steel, which enjoys a large market share due to its low cost and simple manufacturing process. However, it also suffers from disadvantages such as heavy weight, poor heat dissipation, susceptibility to rust, and low strength. With the growing domestic market for new energy vehicles, steel wheel rims are gradually being phased out due to their material drawbacks. New energy vehicle manufacturers are actively seeking high-performance carbon fiber wheel rims to replace steel rims. The challenge lies in achieving both structural strength and lightweight design for carbon fiber wheel rims. Summary of the Invention

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0051] Combination Figure 1-4As shown, this embodiment of the present disclosure provides a lightweight wheel hub, including: a rim 1, a hub 3, and spokes 2. A tire is fitted on the outer side of the rim 1. The hub 3 is located at the center of the rim 1 and is connected to the wheel mounting axle of the vehicle. The hub 3 and the rim 1 are connected by a plurality of spokes 2, which are spaced around the central axis of the rim 1. Each spoke 2 includes: a first front side 23, a second front side 24, a through hole 21, and a groove 22. The rim 1 and spokes 2 are made of carbon fiber material to reduce the overall weight. The hub 3 can be made by wrapping an inner metal disc with outer carbon fiber. The spokes 2 also include: a left side 25, a right side 26, and a rear side 27.

[0052] The first front side 23 is connected to the wheel rim 1 on one side;

[0053] The second front side 24 is connected to the first front side 23 on one side and to the hub 3 on the other side.

[0054] A through hole 21 is provided on the first front side 23; it extends from the first front side 23 to the rear side 27.

[0055] The groove 22 is provided on the second front side 24, with one end extending to the first front side 23 and the other end extending to the hub 3.

[0056] The lightweight wheel hub provided in this embodiment of the present disclosure, through the through holes 21 and grooves 22 provided on the spokes 2, not only greatly reduces the weight of the wheel hub, but also increases airflow and improves heat dissipation. The wheel hub is made of carbon fiber material, which greatly reduces the weight of the entire wheel hub. It has extremely high strength and rigidity and can withstand large loads and impacts, thereby improving the service life and safety of the wheel hub, and thus improving the fuel economy and driving efficiency of the car.

[0057] In some embodiments, the first front side 23 includes one or more of the following:

[0058] The first front side 23 is connected to the rim 1 at the edge of the wheel flange; this increases the contact area, disperses the pressure from the tire, and improves the overall load-bearing capacity of the wheel hub.

[0059] The width of the first front side 23 where it meets the rim 1 is greater than the center width; while maintaining lightweight design, it ensures connection strength and prevents breakage when subjected to external forces.

[0060] The width at the junction of the first front side 23 and the second front side 24 is greater than the center width; while maintaining lightweight design, the connection strength is ensured, making it less prone to breakage when subjected to external forces.

[0061] The edge of the first front side 23 (i.e. the edge where the first front side 23 connects with the left side 25 and the right side 26) is an arc-shaped structure; the arc-shaped structure helps to reduce wind resistance and improve the aerodynamic performance of the vehicle.

[0062] The edge of the first front side 23 (i.e., the edge where the first front side 23 meets the left side 25 and the right side 26) has a chamfered structure. The chamfer is a rounded arc. This reduces wind resistance, reduces stress concentration, and avoids material fatigue or damage caused by excessive local stress.

[0063] In some embodiments, the through hole 21 includes one or more of the following:

[0064] The through hole 21 is an elliptical through hole 21; while reducing weight, it can adjust the rigidity distribution of the spokes 2 to a certain extent, so that the hub has a certain degree of flexibility while maintaining sufficient strength, which helps to absorb road impact.

[0065] The through hole 21 is parallel to the axis of the rim 1; maintaining the structural symmetry of the hub and ensuring the balance of the hub during rotation.

[0066] The edge of the through hole 21 is chamfered to reduce stress concentration and prevent the spokes 2 from cracking or breaking at this point.

[0067] The through hole 21 is located at the center of the first front side 23; it helps to evenly distribute the stress on the spokes 2 and improve the overall stability of the hub.

[0068] The area ratio of the projection surface of the through hole 21 and the first front side surface 23 along the axis of the rim 1 is 1:1. This achieves lightweight design while maintaining structural strength.

[0069] In some embodiments, the groove 22 includes one or more of the following:

[0070] The inner side of the groove 22 is provided with a draft angle; this helps to make demolding easier during the manufacturing process and reduces difficulties in the production process.

[0071] A chamfer structure is provided between the inner side surface of the groove 22 and the inner bottom surface of the groove 22; this reduces stress concentration and prevents the spokes 2 from cracking or breaking at this point.

[0072] The groove 22 has a chamfered edge. This helps reduce stress concentration and avoids material fatigue or damage caused by excessive local stress.

[0073] In some embodiments, the hub 3 includes a central hole 32, a bolt connection hole 33, and a groove 22 extending to the edge of the bolt connection hole 33.

[0074] In some embodiments, the second front side 24 includes one or more of the following:

[0075] The edge of the second front side 24 (i.e. the edge where the second front side 24 connects with the left side 25 and the right side 26) has a chamfered structure to reduce stress concentration.

[0076] The second front side 24 is recessed inward relative to the first front side 23 toward the hub 3;

[0077] The edge of the second front side 24 (i.e. the edge where the second front side 24 connects with the left side 25 and the right side 26) is an arc-shaped structure;

[0078] The second front side 24 converges from the first front side 23 toward the hub 3.

[0079] In some embodiments, the hub 3 further includes a draft groove 31, the number of which corresponds to the number of spokes 2, and is located on the front side of the hub 3 between adjacent spokes 2.

[0080] In some embodiments, the inner side of the rim 1 is a groove bottom 11, and the left side 25, right side 26, and rear side 27 are connected to the groove bottom 11. This improves the overall strength and stability of the wheel hub.
