Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automotive parts, and in particular to the technical field of automotive wheel hubs. Background Technology
[0002] In the automotive system, the wheel hub, as a key component connecting the axle and the tire, is particularly important in how it is fixed.
[0003] Car wheel bolts typically secure the wheel rim with 4 to 6 bolts, and these bolts are usually exposed. This design has several drawbacks. First, with one end of the bolt exposed, it can be easily removed with ordinary tools, making the wheel rim and tire vulnerable to theft. Second, the exposed design lacks effective protection and waterproofing, allowing mud, gravel, and corrosive substances to cause physical wear and chemical damage. Rainwater seepage can also lead to rust, affecting the bolt's lifespan, increasing maintenance costs, and in severe cases, even causing the bolt to break, threatening driving safety. Summary of the Invention
[0004] The purpose of this invention is to solve the problems in the prior art by proposing an automobile wheel hub that can solve the above problems.
[0005] To achieve the above objectives, this utility model proposes an automobile wheel hub, including a rim body and a spoke body. The spoke body has a mounting groove at its center, and a through hole is formed at the center of the mounting groove. Several bolt holes are arranged around the outer side of the through hole. A mounting sleeve is threaded into the through hole, and a protective cover is connected to the mounting sleeve. The protective cover is installed on the top of the mounting groove. Several locking grooves are formed in a ring shape on the through hole, and a spring is installed in each locking groove. A magnetic insert is connected to the end of each spring. An annular groove is formed on the outer side of the mounting sleeve, and the magnetic insert connects the annular groove and the locking groove. A driving groove is provided inside the mounting sleeve, and a cover is installed on the outer side of the driving groove.
[0006] Preferably, the top of the magnetic insert is provided with a guide slope.
[0007] Preferably, the drive slot is a hexagonal slot.
[0008] Preferably, the bottom outer side of the mounting cylinder is provided with a threaded portion, the bottom of the through hole is provided with a threaded groove, the threaded portion and the threaded groove are threadedly installed, and the annular groove is provided between the threaded portion and the protective cover.
[0009] Preferably, the outer periphery of the protective cover is provided with a sealing ring groove, and a sealing ring is provided on the sealing ring groove, and the sealing ring is sealed and installed with the inner wall of the mounting groove.
[0010] The beneficial effects of this utility model are as follows: This utility model protects the wheel hub bolts with a protective cover, effectively reducing the risk of wheel hub and tire theft. The magnetic plug locks the mounting cylinder to the wheel spoke body, preventing the protective cover from being disassembled by ordinary tools. The protective cover can isolate the bolts from contact with mud, gravel, rainwater and corrosive substances, reducing physical wear and chemical corrosion, slowing down the rusting rate of the bolts, thereby extending the service life of the bolts, reducing maintenance and replacement costs, and ensuring driving safety.
[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0015] In the diagram: 1. Rim body; 2. Spoke body; 3. Mounting groove; 4. Through hole; 5. Bolt hole; 6. Mounting cylinder; 61. Annular groove; 62. Threaded part; 63. Drive groove; 7. Protective cover; 8. Locking groove; 9. Magnetic insert; 10. Cover; 71. Sealing ring. Detailed Implementation
[0016] See Figure 1 , Figure 2 , Figure 3 A type of automobile wheel hub includes a rim body 1 and a spoke body 2. The spoke body 2 has a mounting groove 3 at its center, and a through hole 4 is formed at the center of the mounting groove 3. Several bolt holes 5 are arranged around the outside of the through hole 4. A mounting cylinder 6 is threaded into the through hole 4. A protective cover 7 is connected to the mounting cylinder 6 and is installed on the top of the mounting groove 3. Several locking grooves 8 are formed in a ring shape on the through hole 4. A spring is provided in the locking groove 8, and a magnetic plug 9 is connected to the end of the spring. An annular groove 61 is formed on the outside of the mounting cylinder 6. The magnetic plug 9 connects the annular groove 61 and the locking groove 8. A drive groove 63 is provided inside the mounting cylinder 6, and a cover 10 is installed on the outside of the drive groove 63.
[0017] The locking groove 8 and the bolt hole 5 are staggered.
[0018] The top of the magnetic insert 9 is provided with a guide slope.
[0019] The drive slot 63 is a hexagonal slot.
[0020] During disassembly, insert a special hexagonal tool into the hexagonal groove. A magnet is located at the position where the hexagonal tool matches the locking groove. The magnet and the magnetic insert generate a repulsive force, causing the magnetic insert to retract into the locking groove. Then, by rotating the tool, the mounting cylinder 6 can be disassembled.
[0021] The bottom outer side of the mounting cylinder 6 is provided with a threaded part 62, and the bottom of the through hole 4 is provided with a threaded groove. The threaded part 62 and the threaded groove are threadedly installed, and the annular groove 61 is provided between the threaded part 62 and the protective cover 7.
[0022] The outer periphery of the protective cover 7 is provided with a sealing ring groove, and a sealing ring 71 is provided on the sealing ring groove. The sealing ring 71 is sealed and installed with the inner wall of the mounting groove 3.
[0023] The sealing ring acts as a waterproof barrier, preventing external moisture from entering the mounting groove.
[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
