[0052] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0053] References to "one embodiment" or "example" or "example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed herein. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0054] An embodiment of the present invention provides a spoke, such as Figure 1 , Figure 2 and Figure 8 As shown, the spoke includes a hub mounting portion 100, a rim mounting portion 200 arranged opposite to the hub mounting portion 100, and a transition portion 300 connected between the hub mounting portion 100 and the rim mounting portion 200. The hub mounting portion 100 is used to be connected to the axle, and the rim mounting portion 200 is used to be connected to the rim. The transition portion 300 includes a transition portion body 310 and at least one reinforcing rib 320. The transition portion body 310 is connected between the hub mounting portion 100 and the rim mounting portion 200, and the first end of the transition portion body 310 surrounds the hub mounting portion 100, and the second end of the transition portion body 310 surrounds the rim mounting portion 200. At least one air hole 311 is formed on the transition portion body 310, and a reinforcing rib 320 is formed at the edge of the at least one air hole 311.

[0055] like Figure 3 As shown, the reinforcing rib 320 includes a basic reinforcing rib 323, a first reinforcing portion 321, and a second reinforcing portion 322. The basic reinforcing rib 323 is arranged around the corresponding air hole 311, and the first reinforcing portion 321 and the second reinforcing portion 322 are both arranged at the edge of the basic reinforcing rib 323. The first reinforcing portion 321 is located on the side of the corresponding air hole 311 close to the second end of the transition portion body 310, and the second reinforcing portion 322 is located on the side of the corresponding air hole 311 close to the first end of the transition portion body 310.

[0056] The first reinforcement portion 321 and the second reinforcement portion 322 form an integral structure, and one of the first reinforcement portion 321 and the second reinforcement portion 322 is turned outward to the outside of the transition portion body 310, and the other of the first reinforcement portion 321 and the second reinforcement portion 322 is turned inward to the inside of the transition portion body.

[0057] The air holes 311 are provided on the spokes, which can reduce the weight of the spokes and achieve lightweighting of the spokes, and can improve the ventilation performance of the spokes, which is helpful for heat dissipation of the wheel during the driving of the vehicle. In the embodiment of the present invention, at least one air hole 311 is provided with a reinforcing rib 320 at the edge, and the stress at the edge of the air hole 311 provided with the reinforcing rib 320 can be at least partially transferred to the corresponding reinforcing rib 320, so as to avoid the cracking and failure of the air hole 311 and improve the fatigue life of the spokes.

[0058] Furthermore, the reinforcing rib 320 includes a basic reinforcing rib 323, which can integrally reinforce the edge of the air hole 311. In addition, the reinforcing rib 320 also includes a first reinforcing portion 321 and a second reinforcing portion 322 formed on the basic reinforcing rib 323. Since the stress states of the hub mounting portion 100 and the rim mounting portion 200 during the use of the spoke are different, the flipping directions of the first reinforcing portion 321 and the second reinforcing portion 322 are different. The corresponding position on the air hole 311 can be reinforced according to the stress states of the hub mounting portion 100 and the rim mounting portion 200 during the use of the spoke, thereby further improving the strength at the edge of the air hole 311.

[0059] In the embodiment of the present invention, the number of the air holes 311 is not particularly limited. Figure 1 In the embodiment shown in , the spokes are formed with a plurality of air holes 311. Further, the reinforcing ribs 320 may be provided on only one or a few of the plurality of air holes 311, or may be provided on each of the air holes 311.

[0060] Combine the following Figure 5a , Figure 5b , Figure 6a , Figure 6b The effect of providing reinforcing ribs is briefly described.

[0061] Figure 5a The figure shows the stress distribution of the outer surface of the spoke without reinforcing ribs at the air holes. From light blue to dark red, the stress increases. Figure 5a It can be seen that stress occurs at the edge of the vent. Figure 5b Schematic diagram of stress distribution on the outer surface of a spoke with reinforcing ribs arranged at the air holes is shown in FIG. , from which it can be seen that the stress is concentrated at the reinforcing ribs.

[0062] Figure 6a The figure shows the stress distribution diagram of the inner surface of the spoke without reinforcing ribs at the air hole. From light blue to dark red, the stress increases. Figure 6a It can be seen that stress occurs at the edge of the vent. Figure 6bSchematic diagram of stress distribution on the inner surface of a spoke with reinforcing ribs arranged at the air holes is shown in FIG. , from which it can be seen that the stress is concentrated at the reinforcing ribs.

[0063] In the embodiment of the present invention, the first reinforcing portion 321 and the second reinforcing portion 322 are formed as an integral structure, so that there are stress concentration points on the reinforcing rib 320 due to "fracture" or "cutting", thereby improving the overall strength of the reinforcing rib 320. Figure 8 and Fig. 9 As shown, a torsion structure is formed at the junction of the first reinforcement part 321 and the second reinforcement part 322. The spoke is formed by a stamping process, and a torsion structure is formed at the junction of the first reinforcement part 321 and the second reinforcement part 322, which will produce work hardening and further improve the overall strength of the reinforcement rib 320.

[0064] In the embodiment of the present invention, there is no particular limitation on the specific positions of the first reinforcement portion 321 and the second reinforcement portion 322. For example, the first reinforcement portion 321 may be turned inside out to the inside of the transition portion body 310, and the second reinforcement portion 322 may be turned outside to the outside of the transition portion body 310. Of course, the embodiment of the present invention is not limited thereto, and the first reinforcement portion 321 may be turned outside to the outside of the transition portion body 310, and the second reinforcement portion 322 may be turned inside out to the inside of the transition portion body 310.

[0065] As an optional implementation, Figure 3 As shown, the second reinforcement part 322 includes a connecting part 322a and a flange part 322b, wherein the connecting part 322a is arranged at the edge of the base reinforcement rib 323 of the corresponding air hole 311 and is located outside the transition part body 310, and the flange part 322b is flipped from the connecting part 322a to a state of being in contact with the connecting part 322a. By flanging the second reinforcement part 322, the strength of the second reinforcement part 322 can be improved.

[0066] In the embodiment of the present invention, there is no special limitation on the height h3 of the second reinforcement part 322 protruding from the outer surface of the transition part body 310. Optionally, h3 may be between 2 mm and 14.6 mm. According to simulation tests, h3 selected within the above range can improve the strength of the second reinforcement part 322.

[0067] There is no particular limitation on the specific shape of the second reinforcement portion 322. Optionally, the shape of the second reinforcement portion 322 may be a circular arc or an elliptical arc.

[0068] It has been found through testing that when the second reinforcement portion 322 is in an elliptical shape, the effect of dispersing the edge stress of the corresponding air hole 311 is better than that when the second reinforcement portion 322 is in an arc shape.

[0069] As another optional implementation, the second reinforcement portion 322 may also include a plurality of arc segments connected end to end in sequence, and the curvature radii of the plurality of arc segments are not completely the same.

[0070] As an optional embodiment, the first reinforcement portion 321 includes an arc-shaped reinforcement portion 321a and two lateral reinforcement portions 321b, the arc-shaped reinforcement portion 321a is arranged at the end of the corresponding air hole 311, and the two lateral reinforcement portions 321b are respectively located at both ends of the arc-shaped reinforcement portion 321a and are respectively connected to the two ends of the second reinforcement portion 322.

[0071] As the name implies, the arc-shaped reinforcement portion 321 a is arc-shaped, which can further avoid stress concentration.

[0072] Optionally, the shape of the arc-shaped reinforcement portion 321 a may be a circular arc or an elliptical arc.

[0073] Similarly, when the arc-shaped reinforcement portion 321 a is in an elliptical shape, the effect of dispersing the edge stress of the corresponding air hole 311 is better than that when the arc-shaped reinforcement portion 321 a is in an arc shape.

[0074] Optionally, the arc-shaped reinforcement portion 321a may also include a plurality of arc-shaped segments connected end to end, and the curvature radii of the plurality of arc-shaped segments are not completely the same.

[0075] As an optional embodiment, the minimum distance between the two lateral reinforcements 321b is smaller than the distance between the two ends of the arc-shaped reinforcement 321a, and the minimum distance between the two lateral reinforcements 321b is smaller than the distance between the two ends of the second reinforcement 322. In other words, the shape of the through hole defined by the reinforcement rib 320 in the corresponding air hole 311 is roughly gourd-shaped.

[0076] The inner contour of the roughly gourd-shaped through hole is streamlined, which can reduce the steepness of the stress gradient at the edge of the hole. In addition, the edge of the hole does not have a sharp turn, so the stress transition around the hole is smoother.

[0077] In the embodiment of the present invention, the distance between the two ends of the arc-shaped reinforcement portion 321 a may be greater than the distance between the two ends of the second reinforcement portion 322 .

[0078] Of course, the embodiment of the present invention is not limited thereto, and the distance between the two ends of the arc-shaped reinforcement portion 321 a may also be less than or equal to the distance between the two ends of the second reinforcement portion 322 .

[0079] In the embodiment of the present invention, setting a reasonable air hole shape can also play a role in increasing the strength of the transition part body 310. It is found through testing that, as an optional embodiment, when the maximum distance L between the arc-shaped reinforcement part 321a of the first reinforcement part 321 and the second reinforcement part 322 is between 30mm and 93mm, and the distance K between the two lateral reinforcement parts 321b is between 20mm and 30mm, the reinforcing rib 320 has the best effect of increasing the strength of the transition part body 310.

[0080] In the embodiment of the present invention, Figure 4 As shown, the maximum distance L between the arc-shaped reinforcement part 321a of the first reinforcement part 321 and the second reinforcement part 322 is greater than the distance K between the two lateral reinforcement parts 321b, that is, the length of the air hole defined by the reinforcing rib 320 is greater than the width. When an external load is applied to the transition part body 310, the length direction (or long axis direction) of the air hole can provide a larger distribution area to disperse the stress, thereby helping to more evenly disperse the stress around the air hole and reduce the stress concentration effect caused by sharp corners. In addition, after the stress concentration is reduced, the fatigue life of the material of the transition part body 310 can be effectively improved.

[0081] In the embodiment of the present invention, the specific verticals of L and K can be determined according to the load received by the spokes in a specific application scenario, so as to provide the best stress dispersion effect in the direction of maximum stress.

[0082] As an optional implementation, along the thickness direction of the transition portion body 310 , the dimension h1 of the arc-shaped reinforcement portion 321 a is between 2 mm and 13 mm.

[0083] Further optionally, along the thickness direction of the transition portion body 310 , the size of the arc-shaped reinforcement portion 321 a is 12.5 mm.

[0084] As an optional implementation, the height h2 of the basic reinforcement rib 323 protruding from the outer surface of the transition portion body 310 is between 2 mm and 12 mm.

[0085] Further optionally, the height of the basic reinforcement rib 323 protruding from the outer surface of the transition portion body 310 is 9.6 mm.

[0086] Because the first end of the transition portion body 310 is connected to the hub connecting portion 100, and the hub connecting portion 100 is used to be fixed on the axle, during use, the force applied to the first end of the transition portion body 310 is greater than the force applied to the second end of the transition portion body 310. In order to improve the integrity and strength of the spoke, optionally, the distance X1 between the first reinforcement portion 321 and the second end is not greater than the distance X2 between the second reinforcement portion 322 and the first end.

[0087] As an optional embodiment, the distance X1 between the first reinforcement portion 321 and the second end of the transition portion body 310 does not exceed 30 mm, which will not affect the installation of the valve stem and the service life of the transition portion body 310. Further, the distance X1 between the first reinforcement portion 321 and the second end of the transition portion body 310 is 8 mm. It should be noted that the distance X1 between the first reinforcement portion 321 and the second end of the transition portion body 310 can be 0, that is, the first reinforcement portion 321 can be connected to the rim mounting portion 200 at the second end of the transition portion body 310.

[0088] Optionally, the distance X2 between the second reinforcement portion 322 and the first end of the transition portion body 310 is not more than 40 mm. Optionally, X2 may be 9.4 mm. It should be noted that the distance X2 between the second reinforcement portion 322 and the first end of the transition portion body 310 may be 0, that is, the second reinforcement portion 322 may be connected to the hub mounting portion 100 at the first end of the transition portion body 310.

[0089] Of course, the present invention is not limited thereto, and as an optional implementation, X1 may also be greater than or equal to X2.

[0090] As described above, in order to reduce the overall weight of the spoke and improve the overall strength of the spoke, optionally, a plurality of air holes 311 are formed on the transition portion body 310, and each of the plurality of air holes 311 is correspondingly provided with a reinforcing rib 320. In the embodiment of the present invention, there is no special limitation on the location of the air holes 311, as long as the stress concentration area on the transition portion body 310 is avoided and the holes are not opened at the location with the maximum stress.

[0091] In order to improve the strength of the second end of the transition portion, optionally, the transition portion 300 may further include at least one connecting rib 330 , and the connecting rib 330 is connected between two adjacent reinforcing ribs 320 .

[0092] In order to further improve the strength of the second end of the transition portion, optionally, the connecting rib 330 is connected to the rim mounting portion 200 .

[0093] In this embodiment of the present invention, there is no special limitation on the specific structure of the hub mounting portion 100. Optionally, the hub mounting portion 100 includes a planar mounting portion 110 and a curved transition portion 120. The planar mounting portion 110 is used to be connected to the vehicle frame, and the curved transition portion 120 is connected between the planar mounting portion 110 and the first end of the transition portion body 310.
