In addition, the automobile wheel hub body 1 can be protected by the corrosion-resistant layer 7 and the wear-resistant layer 8 to prevent the automobile wheel hub body 1 from being affected by corrosion and wear, thereby avoiding the low strength of most existing automobile wheels at high speeds. When passing over a bumpy road too quickly, the car wheel hub is easily impacted and deformed out of round, causing the tire to leak, posing a safety hazard; and when a longer steel nail is pierced by the tire, the steel nail is easy to pierce the car wheel hub, causing the wheel hub to be scrapped, causing great economic losses to the user.

[0030] In this embodiment: since the materials of the first reinforcement ring 201 and the reinforcement ribs 202 are both high-strength aluminum alloy, when the automobile hub body 1 is installed on the automobile for use, the first reinforcement ring 201 and the reinforcement ribs 202 can reinforce the strength of the automobile hub body 1 during the impact of the automobile hub body 1 passing through a bumpy road surface, thereby preventing the automobile hub body 1 from being deformed and out of round, resulting in tire leakage, thereby achieving the effect of strengthening the strength of the automobile hub body 1.

[0031] As a technical optimization solution of the utility model, a second reinforcement ring 3 is sleeved on the surface of the automobile hub body 1, and the material of the second reinforcement ring 3 is thermal armor protection steel.

[0033] As a technical optimization solution of the present invention, a limiting hole 5 is provided inside the reinforcing ring 203 , and the number of the limiting holes 5 is several and evenly distributed inside the reinforcing ring 203 .

[0034] In this embodiment, the balancing block 4 can be connected to the reinforcement ring 203 by inserting the balancing block 4 into the limiting hole 5, thereby achieving the effect of facilitating the connection of the balancing block 4 to the reinforcement ring 203.

[0035] As a technical optimization solution of the present invention, a balancing block 4 is provided on the rear side of the reinforcing ring 203 , and the surface of the balancing block 4 is smeared with glue and then inserted into the limiting hole 5 to be bonded to the reinforcing ring 203 .

[0036] In this embodiment: by applying glue to the balancing block 4 and then inserting it into the limiting hole 5 and bonding it to the inner wall of the limiting hole 5, the balancing block 4 and the reinforcement ring 203 can be limited together, achieving the effect of conveniently limiting the balancing block 4 and the reinforcement ring 203 together.

[0037] As a technical optimization solution of the utility model, a sealing ring 6 is fixedly sleeved on the surface of the balancing weight 4 , and the surface of the sealing ring 6 contacts the surface of the reinforcement ring 203 .

[0038] In this embodiment: after the balancing block 4 and the reinforcement ring 203 are limited together, the surface of the sealing ring 6 is in contact with the surface of the reinforcement ring, and the sealing ring 6 can seal the limiting hole 5 to prevent water stains from entering the limiting hole 5 and affecting the adhesion of the glue, causing the balancing block 4 to fall off, thereby achieving the effect of preventing water stains from entering the limiting hole 5.

[0039] As a technical optimization solution of the utility model, the corrosion-resistant layer 7 is evenly sprayed on the surface of the automobile hub body 1, and the material of the corrosion-resistant layer 7 is epoxy resin paint.

[0040] In this embodiment: by uniformly spraying the corrosion-resistant layer 7 of epoxy resin coating material on the surface of the automobile hub body 1, the automobile hub body 1 can be made corrosion-resistant, thereby preventing the automobile hub body 1 from being corroded and causing strength attenuation, thereby achieving the effect of making the automobile hub body 1 corrosion-resistant.

[0041] As a technical optimization solution of the utility model, the wear-resistant layer 8 is evenly sprayed on the surface of the corrosion-resistant layer 7, and the material of the wear-resistant layer 8 is organic silicon wear-resistant coating.

[0042] In this embodiment: by uniformly spraying a wear-resistant layer 8 made of silicone wear-resistant coating material on the surface of the corrosion-resistant layer 7, the corrosion-resistant layer 7 and the automobile hub body 1 can be protected, thereby preventing the corrosion-resistant layer 7 and the automobile hub body 1 from being worn, reducing the strength of the automobile hub body 1, and achieving the effect of making the automobile hub body 1 have a wear-resistant function.

[0043] Working principle: First, when the automobile wheel hub body 1 is installed on the automobile for use, when the automobile wheel hub body 1 is impacted by a pothole road, the first reinforcing ring 201 and the reinforcing rib 202 made of high-strength aluminum alloy can strengthen the strength of the automobile wheel hub body 1 to prevent the automobile wheel hub body 1 from deforming and losing roundness and causing tire leakage. When a long steel nail penetrates into the tire, the thermal armor protection steel can provide puncture protection for the automobile wheel hub body 1. The thermal armor protection steel is an existing mature technology that has been published and has high hardness, high strength and excellent resistance to The puncture performance is not described in detail here, so the thermal armor protection steel can provide anti-puncture protection for the automobile hub body 1, preventing the longer steel nails from puncturing the automobile hub body 1 and causing greater losses to the user, and by uniformly spraying the corrosion-resistant layer 7 of epoxy resin coating material on the surface of the automobile hub body 1, the automobile hub body 1 can have a corrosion-resistant function, thereby also preventing the automobile hub body 1 from being corroded and causing strength attenuation, and by uniformly spraying the wear-resistant layer 8 of silicone wear-resistant coating material on the surface of the corrosion-resistant layer 7, the corrosion-resistant layer 7 and the automobile hub body 1 can be protected. The wheel hub body 1 is protected to prevent the corrosion-resistant layer 7 and the automobile wheel hub body 1 from being worn, thereby reducing the strength of the automobile wheel hub body 1, thereby avoiding the problem that the strength of most existing automobile hubs is low. When the vehicle passes through a pothole road at too fast a speed, the automobile hub is easily impacted and deformed, causing the tire to leak, posing a safety hazard. In addition, when the tire is pierced by a long steel nail, the steel nail is easy to pierce the automobile hub, causing the hub to be scrapped, causing a large economic loss to the user. By applying glue to the balance block 4 and inserting it into the limiting hole 5 and bonding it to the inner wall of the limiting hole 5, the balance block 4 can be The balancing weight 4 is limited together with the reinforcement ring 203. At this time, the surface of the sealing ring 6 is in contact with the surface of the reinforcement ring. The sealing ring 6 can seal the limiting hole 5 to prevent water stains from entering the limiting hole 5 and affecting the adhesion of the glue, causing the balancing weight 4 to fall off. This avoids the problem that the balancing weight 4 bonded to the surface of the existing automobile wheel hub is prone to falling off for a long time, causing unbalanced rotation of the automobile wheel hub and affecting the driving quality of the automobile. It should be noted that the balancing weight 4 is a counterweight component installed on the automobile wheel hub body 1. The function of the balancing weight 4 is to keep the wheel hub in dynamic balance under high-speed rotation.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
