Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy wheel hubs, in particular to a lightweight aluminum alloy wheel hub. Background Art

[0002] Many existing automobile manufacturers have adopted lighter aluminum alloys to replace cast iron casting wheels to achieve the purpose of reducing weight. Most lightweight aluminum alloy wheels are provided with through holes suitable for connecting the first heat dissipation hole and the second heat dissipation hole inside the wheel spoke, so that air can flow between the first heat dissipation hole and the second heat dissipation hole to dissipate heat to the wheel spoke, thereby ensuring the normal working state of the wheel hub. A decorative cover is usually embedded in the center hole of the center disk, and the decorative cover is often printed with the brand icon of the corresponding vehicle, and the threaded holes on the peripheral side of the center disk are embedded with wheel nuts, which can also be called countersunk grooves, and the countersunk grooves are for wheel nuts to be embedded; the decorative cover can also prevent debris from entering the center hole, but the decorative cover can only cover the center hole, and the countersunk grooves on the peripheral side of the center disk are often unable to be protected, so that foreign debris enters the countersunk groove and blocks the countersunk groove, which will eventually affect the use of the wheel nut inside; at the same time, after the debris accumulates in the countersunk groove, it is easy to accumulate and adhere to the inner wall of the countersunk groove, which is not conducive to the cleaning of the wheel hub;

[0003] The existing Chinese patent CN215360747U discloses a lightweight single-type aluminum alloy wheel hub, which covers the center hole through the main body and covers the countersunk groove through the mounting arm. Finally, the decorative cover can protect the center hole and the countersunk groove at the same time, reducing the possibility of debris entering the center hole and the countersunk groove, which is conducive to keeping the center hole and the countersunk groove clean;

[0004] However, the elastic clip used for installation in the above-mentioned lightweight single-type aluminum alloy wheel is exposed to the outside, and a raised flip plate and a pull ring are also provided on the elastic clip, so that the entire elastic clip and the structure on the elastic clip are easily collided by external objects, and may also be damaged due to long-term erosion by rainwater.
