[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0022] Example:

[0023] like Figure 1 , 2 As shown, the utility model provides a high-precision automobile hub unit, including a hub bracket 11 and a bearing body 21. The hub bracket 11 is an important supporting structure of the entire hub unit, and a mounting column 12 is arranged on one side thereof. The bearing body 21 is sleeved on this mounting column 12, so as to achieve stable installation and positioning. At the same time, a fixed valve 22 is also installed on this side of the hub bracket 11, and the fixed valve 22 is also sleeved on the mounting column 12. The bearing body 21 is located between the fixed valve 22 and the hub bracket 11, so that the structure of the entire hub unit is more compact and reasonable. An oil supply assembly is arranged on the hub bracket 11. The oil supply assembly is connected to the bearing body 21, and can continuously provide lubricating oil to the bearing body 21, so as to ensure that the bearing always maintains a good lubrication state during operation, effectively avoid various problems caused by insufficient lubrication, and improve the working efficiency and reliability of the hub unit. A connecting piece 23 is also provided on one side of the hub bracket 11, and the connecting piece 23 is sleeved on the bearing body 21, further enhancing the connection stability and integrity between the various parts of the hub unit. It not only plays a role in auxiliary fixing, but also shares the pressure and load borne by the bearing body 21 to a certain extent.

[0024] The oil supply assembly includes an oil supply pump 31. Multiple groups of connection holes are evenly opened on the oil supply pump 31 and the wheel hub bracket 11. The connection screws are inserted into these connection holes to firmly fix the oil supply pump 31 on the wheel hub bracket 11, ensuring that the oil supply pump 31 can remain stable during operation and will not loosen or shift due to vibration or other factors, providing a stable guarantee for the continuous and stable oil supply. An oil storage tank 13 is arranged on one side of the wheel hub bracket 11. The oil storage tank 13 has sufficient capacity to store lubricating oil. The two ends of the oil supply pump 31 are respectively connected to the oil storage tank 13 and the bearing body 21 through connecting pipes, so that the oil supply pump 31 can extract the lubricating oil in the oil storage tank 13 and accurately deliver it to the bearing body 21, thereby realizing continuous oil supply and lubrication of the bearing body 21, effectively solving the problem of bearing lubrication. In order to better protect the oil supply assembly, a protective cover 32 is also arranged on one side of the wheel hub bracket 11. The protective cover 32 is connected to the wheel hub bracket 11 by screws, forming a relatively closed protective cavity. The oil storage tank 13 and the oil supply pump 31 are located in the protective cavity and are well protected. The protective cover 32 can effectively prevent damage to the oil supply assembly caused by external dust, impurities and possible collisions, thereby ensuring the safe operation of the oil storage tank 13 and the oil supply pump 31.

[0025] A rubber pad 24 is provided between the bearing body 21 and the wheel hub bracket 11 and the fixed valve 22. The rubber pad 24 is sleeved on the mounting column 12. They are in direct contact with the bearing body 21, forming a good buffering and protective effect. The rubber pad 24 has good elasticity and flexibility, and can effectively absorb and alleviate the impact and vibration from all directions, thereby reducing the damage to the bearing body 21 and extending its service life. Multiple groups of positioning columns 25 are provided on the wheel hub bracket 11 and the fixed valve 22. The rubber pad 24 is provided with positioning holes 26 corresponding to the positioning columns 25. When installing, the positioning columns 25 will be inserted into the positioning holes 26, which can not only ensure the position accuracy of the rubber pad 24 during installation and prevent it from being offset or misaligned, but also further enhance the connection tightness and stability between the rubber pad 24 and the wheel hub bracket 11 and the fixed valve 22. The rubber pad 24 can better play its role. When encountering bumps or impacts during the driving of the car, the rubber pad 24 can react quickly, absorb energy through its own deformation, and reduce the impact on the bearing body 21. At the same time, the cooperation between the positioning column 25 and the positioning hole 26 also ensures that the rubber pad 24 will not become loose or fall off due to vibration or other factors during long-term use.

[0026] like Figures 2 to 4As shown, a protective cover 14 is provided at one end of the mounting column 12, and the protective cover 14 is sleeved on the fixed valve 22 to form an effective protective barrier. A connecting block 15 is provided inside the protective cover 14, and a connecting groove 16 is provided on the mounting column 12 corresponding to the connecting block 15 shown. When the installation operation is performed, the connecting block 15 will be clamped in the connecting groove 16, and through this tight clamping structure, the protective cover 14 can be firmly fixed on the mounting column 12. The protective cover 14 can not only prevent external dust, impurities, etc. from entering the connection part of the mounting column 12 and other components, ensure the cleanliness and normal operation of its internal structure, but also play a role of buffering and protection to a certain extent, reducing possible collisions and damage. The wheel hub bracket 11 is provided with multiple groups of through holes, and the bolts 27 are inserted into these through holes to achieve a stable connection. It is worth noting that multiple groups of anti-skid teeth are also provided on the bolt 27. When the bolt 27 passes through the through hole, these anti-skid teeth will be in close contact with the inner wall of the through hole. It can greatly enhance the friction and connection stability between the bolt 27 and the wheel hub bracket 11, and prevent loosening or displacement during use. Even if the vehicle encounters severe vibration or other external forces during driving, these anti-slip teeth can ensure that the bolt 27 is still firmly fixed on the wheel hub bracket 11, thereby providing a strong guarantee for the safe and reliable operation of the entire wheel hub unit.

[0027] The specific usage and function of this embodiment are as follows:

[0028] When in use, first ensure that the hub bracket 11 is in a stable state, sleeve the bearing body 21 on the mounting column 12, and sleeve the fixed valve 22 on the mounting column 12 and between the bearing body 21 and the hub bracket 11 to achieve stable installation and reasonable layout. Then, the bearing body 21 is continuously supplied with oil and lubricated by the oil supply assembly set on the hub bracket 11. Start the oil supply pump 31, which will extract the lubricating oil in the oil tank 13 and accurately transport it to the bearing body 21 through the connecting pipe to ensure its good lubrication state. At the same time, install the protective cover 14 at one end of the mounting column 12, sleeve the protective cover 14 on the fixed valve 22, and make the internal connecting block 15 snap into the connecting groove 16 of the mounting column 12 to achieve stable installation of the protective cover 14, thereby effectively blocking dust and impurities from entering and playing a buffering and protective role. On the wheel hub bracket 11, bolts 27 are used to pass through multiple groups of through holes for fixing. Since the anti-skid teeth on the bolts 27 are in close contact with the inner wall of the through hole, the stability of the connection can be ensured to prevent loosening and displacement. During the driving of the car, the rubber pad 24 will play a buffering and protective role between the bearing body 21 and the wheel hub bracket 11 and the fixed valve 22, absorbing and alleviating impact force and vibration. The cooperation between the positioning column 25 and the positioning hole 26 can ensure that the rubber pad 24 is accurately positioned and tightly connected. The protective cover 32 can provide good protection for the oil supply assembly and ensure its safe operation. Through such a series of operations and settings, the high-precision automobile hub unit can work stably and reliably during the driving of the vehicle, ensuring the performance and safety of the vehicle.
