[0010] In summary, this utility model has the following beneficial effects:

[0011] 1. The main body is provided with a first reinforcing part and a second reinforcing part. The projection of the first reinforcing part on the main body and the projection of the second reinforcing part on the main body can overlap each other, thereby increasing the thickness of the central part of the main body to strengthen the structural strength between the main body and the first reinforcing part and between the main body and the second reinforcing part.

[0012] 2. A first groove is provided on the first reinforcing part and a second groove is provided on the second reinforcing part, which can reduce the weight of the spokes, reduce the overall weight of the wheel hub, and make the wheel hub lighter.

[0013] 3. The centers of the first groove and the second groove are not on the same straight line, so that the first groove and the second groove 231 are misaligned, thereby preventing the first groove and the second groove from overlapping and further ensuring the structural strength of the spokes.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figures 1 to 2 This embodiment discloses a motorcycle wheel hub including a rim 300, an axle hub 100 is disposed at the center of the rim 300, and three spokes 200 are fixedly connected between the rim 300 and the axle hub 100. The three spokes 200 are equidistantly distributed so that they can be evenly stressed.

[0019] The spoke 200 includes a body 210, which includes a first end face 211 and a second end face 212. The first end face 211 is provided with a first reinforcing portion 220 that partially covers the first end face 211, and the second end face 212 is provided with a second reinforcing portion 230 that partially covers the second end face 212. The body 210 also includes a first side 213 and a second side 214, which are opposite to each other. The first reinforcing portion 220 extends from the first side 213 to the second side 214, and the second reinforcing portion 230 extends from the second side 214 to the first side 213. The first reinforcing part 220 extends from one end toward the second side 214 to the side where the second reinforcing part 230 is located, so that the projections of the first reinforcing part 220 and the second reinforcing part 230 on the main body 210 can overlap. This allows both the first reinforcing part 220 and the second reinforcing part 230 to extend beyond the center of the main body 210, increasing the thickness of the center portion of the main body 210 to strengthen the structural strength between the main body 210 and the first reinforcing part 220, as well as between the main body 210 and the second reinforcing part 230. Compared to a structure where the first reinforcing part 220 and the second reinforcing part 230 completely cover the main body 210, this design reduces overall weight while maintaining structural strength, making the wheel hub lighter.

[0020] The first reinforcing part 220 has multiple first grooves 221 extending from its surface toward the main body 210, thereby reducing its mass and making the wheel hub lighter. The second reinforcing part 230 has multiple second grooves 231 extending from its surface toward the main body 210, also reducing its mass and making the wheel hub lighter. Specifically, the centers of the first grooves 221 and second grooves 231 are not on the same straight line, allowing them to be misaligned and preventing them from overlapping, thus ensuring the structural strength of the spokes 200.

[0021] A first reinforcing rib 222 is provided at the end of the first reinforcing part 220 that connects to the rim 300. The first reinforcing rib 222 is located within the triangular area formed by the connection between the first reinforcing part 220 and the rim 300. The side of the first reinforcing rib 222 that is not connected to the first reinforcing part 220 or the rim 300 has an arc-shaped structure. The first reinforcing rib 222 increases the connection strength between the first reinforcing part 220 and the rim 300, while the arc-shaped structure also prevents stress concentration and ensures the structural strength of the first reinforcing rib 222.

[0022] A second reinforcing rib 232 is provided at the end of the second reinforcing part 230 that connects to the rim 300. The second reinforcing rib 232 is located within the triangular area formed by the connection between the second reinforcing part 230 and the rim 300. The side of the second reinforcing rib 232 that is not connected to the second reinforcing part 230 and the rim 300 has an arc-shaped structure. The second reinforcing rib 232 can increase the structural strength at the connection between the second reinforcing part 230 and the rim 300, and the arc-shaped structure can also prevent stress concentration and ensure the structural strength of the second reinforcing part 230.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
