Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub nuts, and more specifically, to an automotive wheel hub nut. Background Technology

[0002] Wheel nuts are crucial small components in automotive wheel assemblies. Their primary function is to securely fasten the wheel rim to the axle. Visually, a wheel nut is typically a threaded metal cylinder, usually made of high-strength steel to withstand the significant forces generated during vehicle operation, including the vehicle's weight, traction during acceleration, braking force, and impacts from road bumps. In terms of size, the wheel nut must precisely match the bolts on the wheel rim and axle. Wheel nut sizes vary between different vehicle models, depending on factors such as the vehicle's intended use and load-bearing capacity. For example, wheel nuts for small passenger cars may be relatively small, while those for heavy vehicles like large trucks and SUVs will be larger and thicker to ensure sufficient tightening force.

[0003] In complex road conditions, corrosion can occur between wheel nuts and bolts. When vehicles travel on wet and rainy roads, moisture can easily penetrate the gaps between the nuts and bolts, continuously providing conditions for corrosion. In cold regions, roads treated with de-icing agents are even more problematic. The salts in de-icing agents, such as sodium chloride, are highly corrosive. Once they come into contact with the metal nuts and bolts, they accelerate the oxidation-reduction reaction, exacerbating the corrosion problem. Once corrosion occurs, the friction between the nuts and bolts changes, breaking the originally precise fit. This can cause the nuts to gradually loosen during vehicle operation. With vehicle vibrations, the loosening worsens, ultimately leading to unstable wheel connections and seriously affecting driving safety.

[0004] How to design a car wheel nut to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0023] Example, refer to Figures 1-5A type of automotive wheel hub nut includes a nut body 1, a flange 2 on the nut body 1, a sealing cap 3 on the top of the nut body 1, a first internal thread 4 on the inner side of the nut body 1, anti-slip texture 5 on the bottom of the flange 2, a groove on the bottom of the flange 2 in an annular shape, a sealing gasket 6 fixedly connected to the bottom of the flange 2, a connecting platform 7 fixedly connected to the top of the nut body 1 in an annular shape, an external thread 8 on the outer side wall of the connecting platform 7, an annular groove 9 on the top of the nut body 1, a sealing ring fitted inside the annular groove 9, the sealing ring being located between the nut body 1 and the sealing cap 3, a second internal thread 10 on the inner side wall of the sealing cap 3, the external thread 8 engaging with the second internal thread 10, a liquid reservoir 11 on the inner side of the sealing cap 3, the liquid reservoir 11 being hollow, a threaded hole 12 on the outer side wall of the nut body 1, and a screw 13 inside the threaded hole 12.

[0024] The flange 2 and the nut body 1 are integrally formed. The sealing cover 3 is semi-circular. The flange 2 is located at the bottom. The nut body 1 is hexagonal in shape. The first internal thread 4 is right-handed. The anti-slip pattern 5 is serrated. The groove is annular. The sealing gasket 6 is located inside the groove. The liquid storage box 11 is made of plastic and is sealed. The inside of the liquid storage box 11 is coated with anti-rust paint. The screw 13 has an internal hexagonal groove and engages with the nut body 1 through the threaded hole 12.

[0025] The working principle of this type of automotive wheel hub nut is as follows: The nut is installed on the bolt using a tool to fix the vehicle wheel hub. During this process, anti-slip grooves 5 are provided, which contact the wheel hub to increase the friction between the nut and the wheel hub, preventing the nut from falling off the bolt. A sealing gasket 6 is provided, which contacts the wheel hub and is subjected to the squeezing force from the flange 2 during the installation of the nut, sealing the contact surface between the flange 2 and the wheel hub and preventing the first internal thread 4 from contacting the outside air, thus protecting the first internal thread 4 from the influence of the external environment. A liquid reservoir 11 is provided, which is subjected to the squeezing force from the bolt during the installation of the nut, causing the liquid reservoir 11 to crack. The anti-rust paint inside flows out and seeps into the gap between the first internal thread 4 and the bolt, and gradually solidifies, protecting the contact surface between the nut and the bolt from the outside environment. Even if the sealing gasket 6 cracks over time and loses its protective function, the anti-rust paint can still protect the nut and the bolt from rust, protecting the stability of the vehicle wheel hub.
