Description

Technical Field

[0001] The utility model relates to the field of wheels, in particular to a wheel spoke and a wheel. Background Art

[0002] A wheel is installed on a vehicle hub and is a transmission part between a tire and an axle. Heat is generated during both the friction between the wheel and the road surface during driving and the braking process. Especially when continuously using brakes on long downhill sections with heavy loads, the wheel shows a high-temperature phenomenon. Without taking cooling measures, the braking performance will decline, and the tire and the wheel are likely to be damaged more quickly under high-temperature conditions, thus posing a potential safety hazard for driving. Although the wheel spoke is provided with ventilation holes for air circulation to reduce the temperature, the heat dissipation effect of the existing ventilation holes is limited and still difficult to meet the heat dissipation requirements in the above extreme cases. Summary of the Utility Model

[0022] To further illustrate the embodiments, the present utility model provides drawings. These drawings are a part of the disclosure of the present utility model, mainly used to illustrate the embodiments, and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0023] In the description of the present invention, the orientation or positional relationships such as "upper", "lower", "left", "right", "front", "rear", etc. are based on the orientation or positional relationships shown in the drawings, only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] In combination with the accompanying drawings and specific embodiments, the present utility model will be further described below.

[0025] Referring to Figures 1 to 5 As shown, a wheel spoke provided in this embodiment includes a spoke body 10. The spoke body 10 is further provided with a central hole 11 located at the center, mounting holes 12 located in a circle around the central hole 11, and a plurality of ventilation holes 13 located outside the mounting holes 12. Specifically, the number of both the mounting holes 12 and the ventilation holes 13 is ten, and they are evenly distributed in the circumferential direction. The ventilation holes 13 are in an elliptical structure, and each ventilation hole 13 is located between two adjacent mounting holes 12 to better ensure the strength of the spoke body 10. Among them, the spoke body 10 is further provided with vortex fan blades 14 with an air flow guiding structure outside the ventilation holes 13, so that when the spoke body 10 rotates, the air flow is guided to the ventilation holes 13 through the vortex fan blades 14. In this specific embodiment, each ventilation hole 13 is provided with one vortex fan blade 14. Further preferably, the vortex fan blade 14 is configured to rotate counterclockwise in the rotation direction of the spoke body 10, as Figure 3 shown, and in the counterclockwise direction, the vortex fan blade 14 is located at the rear side of the ventilation hole 13 and is inclined toward the side of the ventilation hole 13.

[0026] This embodiment also provides a wheel, which includes a rim 20 and a spoke connected to one axial end of the rim 20. Among them, the spoke is the above-mentioned wheel spoke. Specifically, the outer circle of the spoke body 10 is fixed on the rim 20. At the same time, bolts are used to pass through the mounting holes 12 of the spoke body 10 to fix the spoke on the hub.

[0027] When using the above-mentioned wheel and rotating during driving, such as Figure 3 shown, when rotating counterclockwise, the vortex fan blades 14 can guide the air flow into the ventilation holes 13 at the front end, so that more air flows into the wheel interior in an axial flow manner, bringing a strong air flow and enhancing the air circulation inside and outside the wheel. Even in extreme cases where the wheel is heavily loaded during driving and the brakes are used frequently to generate high temperatures, the heat can be quickly dissipated, keeping the temperatures of the wheel, tire, and brake drum at a certain level, ensuring their normal performance, and improving driving safety and the service life of the wheel.

[0028] Specifically, the above-described configuration structure of the vortex fan blades 14 (i.e., in the rotational direction of the spoke body 10, the vortex fan blades 14 are located at the rear side of the ventilation holes 13 and are inclined toward one side of the ventilation holes 13) is a relatively preferred solution in this embodiment. Of course, in other embodiments, the installation position and structure of the vortex fan blades 14 are not limited to this. For example, the vortex fan blades 14 may not be set to be inclined, or the vortex fan blades 14 may be arranged on one side of the ventilation holes 13 close to the central hole 11 or on one side away from the central hole 11, etc., as long as the air flow can be introduced into the ventilation holes 13; and, the number of the ventilation holes 13 may also be less than ten or more than ten, and the shape of the ventilation holes 13 is not limited to an oval shape, and may also be a circular shape, a polygonal shape, or other irregular shapes, etc.

[0029] Specifically, in this embodiment, the central hole 11 and the mounting holes 12 are provided on the spoke body 10, which is a relatively common mounting structure in the prior art. Of course, in other embodiments, the structure of the central hole 11 and the mounting holes 12 may not be adopted.

[0030] Furthermore, in this embodiment, the spoke body 10 has an annular portion 15 extending toward the inside of the rim 20; the ventilation holes 13 and the vortex fan blades 14 are both provided on the annular portion 15; the setting of the annular portion 15 makes this part form an inwardly concave structure. In this way, the vortex fan blades 14 can be effectively accommodated, so that the vortex fan blades 14 will not protrude outside the wheel or reduce the size of the protrusion outside the wheel.

[0031] The vortex fan blades 14 have a connecting bottom that is adapted to the contour of the spoke body 10. The connecting bottom of the vortex fan blades 14 fits on the spoke body 10 and forms a fixed connection, specifically fixed by welding; to ensure the stable assembly of the vortex fan blades 14.

[0032] The exposed sides of the vortex fan blades 14 (i.e., the other sides except the connecting bottom) are all arc-shaped edges, which eliminate sharp end angles to avoid causing harm to the outside or itself on the basis of ensuring the realization of the diversion; and can also effectively reduce the wind resistance.

[0033] Of course, in other embodiments, the fixing method and shape of the vortex fan blades 14 are not limited to this.

[0034] Although the present invention is specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all are within the protection scope of the present invention.
