Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a lightweight and high-strength automobile wheel hub. Background Art

[0002] As the most important safety component of a car, the car wheel hub is increasingly valued by manufacturers. The lightweight of a car means to reduce the curb weight of the car as much as possible while ensuring the strength and safety performance of the car, thereby improving the car's power, reducing fuel consumption, and reducing exhaust pollution. For environmental protection and energy saving considerations, the lightweight of the car has become the direction of world automobile development. Therefore, it is hoped that various parts of the car, such as the frame, wheel hub, etc., can be lightweight.

[0003] Many existing wheels currently only focus on appearance and ignore structural improvements, resulting in the failure to further reduce the weight of the car wheel. They are usually simple one-piece structures. During use, their spoke structure is single and their supporting performance is limited, resulting in insufficient overall structural strength. However, excessive lightweighting will lead to insufficient strength. Summary of the invention
