Description

Technical Field

[0001] This utility model relates to the field of reinforced bolt structure technology, specifically a reinforced bolt structure for automobile wheel hubs that is easy to disassemble and assemble. Background Technology

[0002] In automobiles, wheel bolts are used to fasten the rim, wheel hub, and brake drum together. A wheel bolt consists of two parts: a head and a shank. The cylindrical section of the shank with external threads is called the threaded section, and the cylindrical section without external threads is called the smooth section.

[0003] For example, Chinese patent CN111692182B discloses an automotive wheel hub bolt, including a screw head and a screw rod. The screw rod includes a knurled section with grooved ridges on its outer surface and a threaded section with external threads. The screw head and the threaded section are located at opposite ends of the knurled section. The bottom surface of the screw head has an annular groove near its edge, forming an annular tip with the side of the screw head. By providing a knurled section on the screw rod, the internal threads of the automotive wheel hub bolt hole can be eliminated, making installation convenient and preventing the bolt from rotating when installing the nut. By providing a guide section on the screw rod, it plays a guiding role in the initial stage of assembly, facilitating installation. By providing a plug and oil felt in the guide section, the oil output can be controlled, making oil replenishment convenient and protecting the threads. By providing a smooth, flat, round screw head, it is prevented from catching debris. However, in the process of using traditional automotive wheel hub bolts, the exposed threads on the surface are prone to corrosion or wear, making it difficult to disassemble the nut and thus difficult to remove the bolt. Therefore, a reinforced bolt structure for automotive wheel hubs that is easy to disassemble and assemble is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides the following technical solution: a reinforced bolt structure for automobile wheel hubs that is easy to disassemble and assemble, comprising: a bolt body 1, a nut 4 sleeved on one end of the bolt body 1, and a sleeve 41 integrally connected to one end of the nut 4, which protects the bolt body 1. Preferably, the bolt body 1 is composed of a threaded section and a smooth section, and both the nut 4 and the sleeve 41 are threadedly installed on the surface of the threaded section. By adding a sleeve 41 to the rear end of the nut 4, the exposed part of the rear end of the bolt body 1 is covered and protected, reducing contact with space and thus reducing corrosion.

[0024] In this embodiment, the insertion segment 2 is disposed at one end of the bolt body 1. The outer surface of one end of the bolt body 1 is integrally mounted with the connecting segment 22, and the insertion segment 2 is sleeved on the outer surface of the connecting segment 22. The insertion segment 2 is a ring structure, and the outer surface of the insertion segment 2 is provided with stripes. During installation, the bolt body 1 can be passed through the wheel hub, and the insertion segment 2 can be inserted into the wheel hub for positioning.

[0025] The outer surface of the connecting section 22 is integrally provided with protrusions 23, and the inner wall of the insertion section 2 is provided with grooves 21 that match the protrusions 23. When the surface stripes are worn and cannot be limited, they can be directly removed and replaced, avoiding the need to replace the entire wheel hub bolts.

[0026] In this embodiment, the top 3 is integrally connected to one end of the connecting section 22. A mounting groove 31 is provided on one side of the outer surface of the top 3. A gasket 32 ​​is embedded inside the mounting groove 31. The outer surface of the gasket 32 ​​is provided with strip-shaped anti-slip texture. The gasket 32 ​​on one side of the top 3 contacts the surface of the wheel hub. The gasket 32 ​​is provided with strip-shaped anti-slip texture, which can increase the friction and prevent the bolts from loosening due to the vibration generated by the wheel hub during use, thereby increasing the tightness of the connection.

[0027] The working principle of this embodiment is as follows:

[0028] During installation, the bolt body 1 can be passed through the wheel hub, the insertion section 2 can be inserted into the wheel hub for limiting, and then the nut 4 can be installed on the threaded part of one end of the bolt body 1 for fixing. The insertion section 2 is sleeved on the surface of the connecting section 22, and the protrusion 23 and the groove 21 are used for limiting. When the surface stripes are worn and cannot limit, it can be directly removed and replaced to avoid replacing the entire wheel hub bolt.

[0029] After installation, the gasket 32 ​​on one side of the top 3 contacts the surface of the wheel hub. The surface of the gasket 32 ​​is provided with strip-shaped anti-slip texture, which can increase friction, prevent the bolts from loosening due to vibration generated by the wheel hub during use, and increase the tightness of the connection.

[0030] By adding a sleeve 41 to the rear end of the nut 4, the exposed part of the rear end of the bolt body 1 is covered and protected, reducing contact with space and thus reducing corrosion. At the same time, the sleeve 41 is threaded to the bolt body 1, increasing the connection part with the bolt body 1. When some threads are worn, the nut 4 can be removed by rotating for easy disassembly.
