Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to an anti-blackening wheel hub with corrosion resistance function. Background Art

[0002] The wheel hub is a cylindrical metal component that supports the inner contour of the tire and is mounted on the axle in the center. It is also called a rim, steel ring, wheel, or tire bell. There are many types of wheel hubs depending on the diameter, width, molding method, and material.

[0003] The manufacturing of wheel hubs involves several key technologies:

[0004] 1. Casting technology: Gravity casting is a basic method in wheel manufacturing. Low-pressure casting compresses liquid alloy under low pressure to make it tightly fill the mold and form it;

[0005] 2. Forging technology: Forging technology is a manufacturing method that uses high pressure to press alloy materials into rough wheels, and then performs subsequent processing. Forged wheels usually have higher strength and better performance;

[0006] 3. Spinning technology. Spinning technology has specific requirements for pressure and temperature during operation. Through the rotation action and extrusion process, the structure of the wheel hub is expanded. The wheel hub produced by this method not only ensures the strength standard but also significantly reduces the weight of the wheel hub;

[0007] 4. Other related technologies, such as heat treatment technology, surface treatment technology, quality inspection and packaging.

[0008] At present, the surface of the wheel hub may undergo special treatment processes, such as electroplating, spraying anti-corrosion coating, anodizing or using nanotechnology. These treatment processes can form a protective film on the surface of the wheel hub to enhance its corrosion resistance and anti-blackening ability. At the same time, in order to further enhance its corrosion resistance and anti-blackening ability, a hub cover will be installed on the surface of the wheel hub. The hub cover generally adopts two installation methods, snap connection and bolt connection. The snap connection is that the edge of the hub cover is designed with a snap structure that matches the snap groove on the edge of the hub. The user only needs to align the hub cover with the hub and press to complete the fixation. The bolt connection is that the surface of the hub cover is designed with a through hole connected to the hub. During installation, the bolts are connected through the through holes on the hub cover and the hub and the connecting holes on the vehicle body.

[0009] However, there is a problem with the above method. The snap connection usually relies on the elastic deformation of the snap structure to achieve connection and fixation. During the installation and removal process, the snap structure needs to undergo deformation such as compression, expansion or bending. These deformations are prone to generate large impact forces. If the user uses excessive force or improper methods when installing or removing the hub cover, the snap structure may generate excessive impact force on the hub surface, which may easily scratch the hub surface and make the coating effect on the hub surface ineffective, affecting the corrosion resistance and anti-blackening ability of the hub. The bolt connection is stable and there is no impact force generated by the snap connection, but when removing the hub cover, the connection between the hub and the vehicle body needs to be released at the same time, affecting the stability of the hub. The present application proposes a solution to this problem and designs a connection mechanism to ensure the installation stability of the hub cover while preventing the hub cover from scratching the hub surface and protecting the coating on the hub surface.
