Description

Technical Field

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

[0002] A car wheel is a rotating component that bears load between the tire and the axle. It mainly consists of two parts: the rim and the spokes. The spokes are between the rim and the rotating shaft to transmit torque.

[0003] The heat dissipation holes in the spokes of traditional wheels are circular through holes. Due to the large spacing between them, the spokes are subjected to greater stress when the car starts, brakes suddenly, runs on bumpy roads, or runs continuously under high load during driving. Over time, the weak parts of the hole walls of the spokes corresponding to the heat dissipation holes are prone to metal fatigue cracking, which affects the service life. Utility Model Content

[0004] The utility model aims to provide a wheel to solve the above-mentioned technical problems.

[0005] To achieve the above purpose, the technical solution of the present invention is: a wheel, including spokes, on which a plurality of heat dissipation holes and a plurality of reinforcement bosses are evenly arranged along the circumferential direction, and the heat dissipation holes and the reinforcement bosses are alternately distributed.

[0006] Preferably, the reinforcing boss is in a special shape or geometric shape.

[0007] Preferably, the reinforcement boss is shield-shaped and is centrally arranged between the two heat dissipation holes.

[0008] Preferably, the reinforcing boss is a structure that is concave inside and convex outside.

[0009] Preferably, the number of the heat dissipation holes and the number of the reinforcement bosses are the same, and the number of the heat dissipation holes and the number of the reinforcement bosses range from 2 to 20.

[0010] Preferably, the spoke includes an annular conical wall and an annular flat plate connected to the smaller end of the annular conical wall, and the heat dissipation holes and the reinforcing boss are provided on the annular conical wall.

[0011] Preferably, the heat dissipation hole is a curved ellipse, and the long axis direction of the heat dissipation hole corresponds to the circumferential direction of the annular cone wall.

[0012] Preferably, the annular flat plate is evenly provided with a plurality of bolt holes along the circumferential direction.

[0013] Preferably, the heat dissipation holes and the bolt holes are arranged alternately, and the bolt hole is centrally arranged on one side between the two heat dissipation holes.

[0014] Preferably, the vehicle further comprises a rim, wherein the spokes are connected to one axial end of the rim.

[0015] The utility model has the following beneficial effects:

[0016] The utility model includes a wheel spoke, on which a plurality of heat dissipation holes and a plurality of reinforcement bosses are evenly arranged along the circumferential direction. The heat dissipation holes and the reinforcement bosses are alternately distributed. This arrangement can greatly reduce the stress on the wheel spoke during driving under various conditions such as starting, sudden braking, bumpy roads, heavy load or continuous high-load operation, thereby increasing the load-bearing load of the wheel. As a result, the weak parts of the hole walls of the wheel spoke corresponding to the heat dissipation holes are less likely to cause metal fatigue cracking, thereby extending the service life of the wheel and adapting to various adverse road conditions and driving modes.

[0026] See Figure 1-5 As shown, as an embodiment of the present invention, a wheel is provided, including spokes, each of which is uniformly provided with a plurality of heat dissipation holes 4 and a plurality of reinforcement bosses 5 along the circumference. The heat dissipation holes 4 and reinforcement bosses 5 are alternately distributed. Specifically, the reinforcement bosses 5 are shield-shaped and centrally located between two heat dissipation holes 4. By providing the shield-shaped reinforcement bosses 5 between the two heat dissipation holes 4, the wheel of the present invention significantly reduces stress on the spokes during various driving conditions, such as starting, sudden braking, rough roads, heavy loads, or continuous high-load operation. This improves the wheel's load-bearing capacity, thereby reducing metal fatigue cracking in the weak areas of the spoke walls corresponding to the heat dissipation holes 4. This extends the wheel's service life and allows it to adapt to various harsh road conditions and driving styles. Furthermore, the shield-shaped reinforcement bosses 5 have a unique appearance, enhancing the overall aesthetics of the wheel. The reinforcing boss 5 of the present invention is pressed by a hydraulic machine. The overall strength of the spoke is significantly improved after pressing, and the load-bearing effect is particularly good, which can enable the wheel to maintain a good stability when starting, emergency braking and high-load operation generate high torque loads under high load.

[0027] Of course, in other cases, the reinforcing boss may be in other shapes besides the shield shape. It may be in a special shape or a geometric shape, such as a rectangle, etc., which is not limited here.

[0028] In this embodiment, the reinforcing boss 5 has a structure that is concave inside and convex outside, so as to facilitate processing and forming, and meet the lightweight requirements while ensuring the structural strength of the spoke.

[0029] In this embodiment, the number of heat dissipation holes 4 and reinforcing bosses 5 is 10, which makes the spacing between the heat dissipation holes 4 and the reinforcing bosses 5 more reasonable, ensuring the strength and stability of the wheel. Of course, in other cases, the number of heat dissipation holes and reinforcing bosses can also be other multiples, such as 12, and this is not limited here.

[0030] In this embodiment, the wheel spoke comprises an annular conical wall 2 and an annular flat plate 3 connected to the smaller end of the annular conical wall 2. The wheel spoke also comprises a rim 1, with the spoke connected to one axial end of the rim 1. Heat dissipation holes 4 and reinforcing bosses 5 are provided on the annular conical wall 2. The heat dissipation holes 4 are curved elliptical in shape, with the major axis of the heat dissipation holes 4 aligned with the circumference of the annular conical wall 2, ensuring the structural strength and stability of the wheel. Of course, the heat dissipation holes can also have other shapes besides elliptical, such as circular, and this is not a limitation here.

[0031] In this embodiment, the annular flat plate 3 is evenly provided with 10 bolt holes 6 along the circumferential direction, the heat dissipation holes 4 and the bolt holes 6 are arranged alternately, and the bolt hole 6 is centrally arranged on one side between two heat dissipation holes 4, which is convenient for installing and locking the wheel, and at the same time makes the force more balanced and stable, thereby ensuring the locking stability of the wheel and the driving stability of the vehicle.

[0032] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims shall fall within the scope of protection of the present invention.
