A spoke for a vehicle wheel

Abstract

This utility model relates to a wheel spoke for an automobile wheel, comprising a disc-shaped spoke body, a cover plate, and an annular wheel plate. Several bolt holes are evenly distributed circumferentially on the cover plate, and several heat dissipation holes are evenly distributed circumferentially on the annular wheel plate. Each heat dissipation hole has a polygonal protrusion corresponding to its outer periphery. The protrusion and the corresponding heat dissipation hole are concentrically arranged. A teardrop-shaped ventilation hole is also provided between every two adjacent heat dissipation holes. The ventilation holes and bolt holes are aligned, while the heat dissipation holes and bolt holes are staggered. The protrusion on the wheel spoke of this utility model strengthens the structural strength around the heat dissipation holes, allowing the wheel to maintain good stability even under high loads during starting, emergency braking, and high-torque loads generated during high-speed operation.

Description

Technical Field

[0001] This utility model relates to the field of automobile wheel technology, and in particular to a wheel spoke. Background Technology

[0002] Car wheels, consisting of steel rims and tires, are like the "feet" of a car and are important rotating components. The steel rim mainly consists of two parts: the rim itself and the spokes. The spokes, acting as the connection point between the wheel and the rotating shaft, transmit torque. During vehicle start-up, braking, and heavy loads, the spokes bear high loads. Over time, this repeated stress can easily lead to metal fatigue cracking around the heat dissipation holes on the spokes. Therefore, there is an urgent need to develop a spoke structure that strengthens the area around the heat dissipation holes. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a more optimized spoke design for automobile wheels.

[0004] This utility model is achieved using the following technical solution: This utility model proposes a car wheel spoke, including a disc-shaped spoke body, the spoke body including a cover plate and an annular wheel plate, several bolt holes are evenly distributed along its circumference on the cover plate, and several heat dissipation holes are evenly distributed along its circumference on the annular wheel plate, each heat dissipation hole has a polygonal protrusion corresponding to its outer peripheral edge, the protrusion and the corresponding heat dissipation hole are concentrically arranged, and a teardrop-shaped ventilation hole is also provided between every two adjacent heat dissipation holes, the ventilation hole and the bolt hole are aligned, and the heat dissipation hole and the bolt hole are staggered.

[0005] Preferably, the boss is an octagonal protrusion.

[0006] Preferably, the boss is formed by integral spinning.

[0007] Preferably, the protrusion height of the boss is 1.5mm.

[0008] Preferably, the width of the boss is between 8 and 12 mm.

[0009] Preferably, the boss protrudes towards the outer or inner side of the disc-shaped spoke body.

[0010] This invention has the following advantages: Each heat dissipation hole has a polygonal protrusion on its outer edge, which significantly improves load-bearing capacity, extending product lifespan and load capacity while also providing a three-dimensional appearance. The teardrop-shaped ventilation holes reduce wheel weight, increase airflow to remove heat, and enhance the overall aesthetics of the wheel. The wheel spokes of this invention maintain good stability even under high loads during starting, emergency braking, and high-torque loads generated during high-speed operation.

[0012] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0013] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0014] See Figure 1-3 As shown in the preferred embodiment of this utility model, a car wheel spoke is provided, including a disc-shaped spoke body 1. The spoke body 1 includes a cover plate 11 and an annular wheel plate 12. Several bolt holes 2 are evenly distributed along the circumference of the cover plate 11. The arrangement of the cover plate 11, the annular wheel plate 12, and the bolt holes 2 are all prior art. Several heat dissipation holes 3 are evenly distributed along the circumference of the annular wheel plate 12. Each heat dissipation hole 3 has an octagonal protrusion 4 corresponding to its outer peripheral edge. The protrusion 4 and the corresponding heat dissipation hole 3 are concentrically arranged. The protrusion 4 strengthens the structural strength around the heat dissipation hole 3, which has a significant effect on improving load-bearing capacity. It not only improves the product's service life and load-bearing capacity but also gives it a three-dimensional appearance. A teardrop-shaped ventilation hole 5 is also provided between every two adjacent heat dissipation holes 3. The teardrop-shaped ventilation hole 5 reduces the weight of the wheel and increases airflow to remove heat while enhancing the overall aesthetics of the wheel. The ventilation hole 5 and the bolt hole 2 are aligned, while the heat dissipation hole 3 and the bolt hole 2 are staggered, so that the bolt hole 2, the heat dissipation hole 3 and the ventilation hole 5 on the wheel spoke are evenly and reasonably distributed.

[0015] The wheel spokes of this embodiment can maintain good stability even when the wheel is under high load during starting, emergency braking, and high torque load generated by high-speed operation.

[0016] In addition to adopting an octagonal structure, the boss 4 can also be other polygonal structures, such as pentagonal or hexagonal structures, in other embodiments.

[0017] In this embodiment, the boss 4 protrudes outward toward the outer side of the disc-shaped spoke body 1, but in other embodiments, the boss 4 may also protrude inward toward the inner side of the disc-shaped spoke body 1.

[0018] In this embodiment, the boss 4 is integrally formed by spinning. The protrusion height of the boss 4 is 1.5mm, and the width of the boss 4 is between 8-12mm, so as to ensure both good manufacturability and structural strength.

[0019] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that any changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
