Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to an automobile wheel hub with a wheel core. Background Art

[0002] Traditional automobile wheel hubs are mostly made of steel or aluminum. Steel hubs are heavy and increase the overall weight of the vehicle, thereby increasing fuel consumption and braking distance. On the other hand, steel hubs are prone to rust without surface treatment. Therefore, steel hubs are gradually replaced by aluminum hubs. Aluminum hubs are mainly made of aluminum alloy and are manufactured using forging or casting processes. Their structure is one-piece. Although aluminum hubs have outstanding performance in terms of lightweight, heat dissipation, and appearance, they are expensive and have poor durability and environmental adaptability.

[0003] Since aluminum alloy is softer and has a lower hardness than steel wheels, it is easily scratched or deformed by impact or scraping. After multiple disassembly and assembly, the parts where the aluminum wheels and axles are installed are prone to damage or wear. In addition, under extremely harsh road conditions or strong impacts, the installation parts may break or directly shatter, reducing driving safety and the service life of the wheels. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the installation part of the wheel hub and the axle is easily damaged or worn, and the installation part may be broken or directly broken under extremely bad road conditions or strong impact, which affects driving safety, and to provide an automobile wheel hub with a wheel core. The strength and hardness of the wheel core of the present invention are higher than that of the wheel hub body, and the wheel core and the wheel hub are interference fit as one, forming an automobile wheel hub with better performance, avoiding damage to the wheel hub installation area, and improving driving safety and the service life of the wheel hub.

[0005] A car wheel hub structure with a wheel core, comprising a wheel hub body and a wheel core, the wheel core is integrally formed, the wheel core has a central wheel axle mounting cylinder and a plurality of bolt mounting cylinders, the plurality of bolt mounting cylinders are evenly distributed on a circumference with the central wheel axle mounting cylinder as the center, the number of the bolt mounting cylinders is the same as the number of the bolt mounting holes of the wheel hub body, the central wheel axle mounting cylinder and the bolt mounting cylinder of the wheel core respectively correspond to the central wheel axle mounting hole and the bolt mounting hole of the wheel hub body, the wheel core is mounted in the wheel hub body, the wheel core and the wheel hub body are interference fit, the central wheel axle mounting cylinder of the wheel core is penetrated in the central wheel axle mounting hole of the wheel hub body, and the plurality of bolt mounting cylinders of the wheel core are respectively penetrated in the corresponding bolt mounting holes of the wheel hub body; the strength and hardness of the wheel core are higher than those of the wheel hub body.

[0006] The wheel core is made of steel or wear-resistant alloy.

[0007] Beneficial effects of the present invention: The present invention installs a high-strength and wear-resistant wheel core on the wheel hub body, and the installation position of the wheel hub and the axle is wear-resistant and not easy to be damaged. Under extremely harsh road conditions or strong impacts, the installation position will not break or directly break, thereby improving driving safety and the service life of the wheel hub.

[0009] See also Figures 1 to 6 As shown, a car wheel hub with a wheel core comprises a wheel hub body 1 and a wheel core 2. The wheel core 2 is integrally formed, and the wheel core 2 has a central wheel axle mounting cylinder 21 and five bolt mounting cylinders 22. The five bolt mounting cylinders 22 are evenly distributed on a circumference with the central wheel axle mounting cylinder 21 as the center. The central wheel axle mounting cylinder 21 and the five bolt mounting cylinders 22 of the wheel core 2 correspond to the central wheel axle mounting hole 11 and the five bolt mounting holes 12 of the wheel hub body 1. The wheel core 2 is installed in the wheel hub body 1. The wheel core 2 and the wheel hub body 1 are interference fit. The central wheel axle mounting cylinder 21 of the wheel core 2 is penetrated in the central wheel axle mounting hole 11 of the wheel hub body 1, and the five bolt mounting cylinders 22 of the wheel core 2 are penetrated in the five bolt mounting holes 12 of the wheel hub body 1. The strength and hardness of the wheel core 2 are higher than those of the wheel hub body 1.

[0010] The wheel core 2 is made of steel or wear-resistant alloy.

[0011] In this embodiment, the hub body 1 is an aluminum hub.
