DETAILED DESCRIPTION

[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 , 2As shown, the utility model provides a silent hub assembly, including a hub body 11, which is the core foundation of the entire device. A bearing body 21 is sleeved on the hub body 11, and the two cooperate with each other to provide key support for the smooth operation of the vehicle. A first limiting groove 12 is provided on the hub body 11, and a sound-absorbing sleeve 22 is provided in the first limiting groove 12. The sound-absorbing sleeve 22 is also tightly sleeved on the hub body 11. The sound-absorbing sleeve 22 is located between the hub body 11 and the bearing body 21, and effectively absorbs various noises generated when the bearing body 21 shakes. In this way, the propagation and reflection of sound are greatly reduced, thereby improving the quietness of the vehicle when driving. A buffer component is provided between the hub body 11 and the bearing body 21. The buffer component is connected to the hub body 11 and is in close contact with the bearing body 21, which can give the bearing body 21 a good buffering effect, effectively reducing the direct friction and collision between the bearing and other components, thereby effectively reducing the generation of noise. At the same time, the stability and reliability of the entire wheel hub assembly are further enhanced, adding an important guarantee for the comfort of vehicle driving. In addition, a fixing valve 23 is also provided at one end of the wheel hub body 11. The fixing valve 23 is sleeved on the wheel hub body 11 and plays a key fixing role, ensuring the stability of the connection between the components and avoiding abnormal noise caused by loose components during vehicle driving.

[0024] like Figure 2 , 3As shown, the buffer assembly includes a mounting ring 31 and a support ring 32. The mounting ring 31 is sleeved on the hub body 11 and is firmly connected to the hub body 11 by screws, ensuring its stability during operation. The support ring 32 is located on one side of the mounting ring 31 and contacts the bearing body 21, and undertakes important support and buffering tasks. The support ring 32 and the mounting ring 31 are connected by multiple groups of connecting parts. The connecting parts are composed of a slider 33 and a connecting rod 34. Multiple groups of slide grooves 35 are provided on the mounting ring 31. The slider 33 can be stuck in these slide grooves 35 and form a slidable connection relationship with the mounting ring 31, so that the slider 33 can move in the track. The two ends of the connecting rod 34 are rotatably connected to the slider 33 and the support ring 32, respectively, so that the entire buffer assembly is more flexible and efficient during operation. A sliding rod 36 is also provided in the slide groove 35, and a through hole is provided in the slider 33 corresponding to the sliding rod 36. Through the through hole, the slider 33 can be smoothly mounted on the sliding rod 36, thereby ensuring the directionality and stability of its movement. A spring 37 is also specially provided between the slider 33 and the mounting ring 31. The spring 37 is mounted on the sliding rod 36 to provide elastic buffering force for the entire buffer assembly. A limit nut is mounted on one end of the sliding rod 36. The limit nut plays a key role in limiting the range of movement of the slider 33, preventing it from sliding excessively and causing system instability.

[0025] like Figure 2 , 4As shown, rubber plates 24 are provided at both ends of the bearing body 21, and two groups of second limiting grooves 13 are provided on the wheel hub body 11. The rubber plates 24 are sleeved on the wheel hub body 11 and clamped in the second limiting grooves 13, so as to achieve a stable installation. One side of the rubber plate 24 contacts the bearing body 21. On the one hand, the rubber plate 24 can play a good limiting role on the bearing body 21, preventing it from excessive displacement or shaking during operation, thereby ensuring the stability of the entire system; on the other hand, the rubber plate 24 can also buffer the vibration and collision between the bearing body 21 and the wheel hub body 11 and other components, thereby avoiding the harsh noise that may be generated by hard contact, and at the same time, it also plays a better protective role on the bearing body 21 and prolongs its service life. Multiple groups of fixing through holes 14 are provided on the fixed valve 23, and multiple groups of fixing grooves 15 are also provided on the wheel hub body 11. The fixing rod 16 can be inserted into two groups of fixing through holes 14 and the fixing grooves 15, thereby achieving a firm fixed connection between the components. This ensures that during the driving of the vehicle, all components can be tightly combined and will not become loose due to vibration or other factors, thereby effectively avoiding abnormal noise caused by looseness and ensuring the stability and quietness of the vehicle. At the same time, multiple groups of silencer shutters 17 are arranged inside the hub body 11, and the silencer shutters 17 further enhance the sound absorption effect of the entire hub, and can reduce noise in multiple directions and at multiple levels, so that the vehicle can maintain a quiet environment when driving.

[0026] The specific usage and function of this embodiment are as follows:

[0027] When in use, the hub body 11 is installed at the corresponding position of the vehicle to ensure that it is stable and reliable. Then, the bearing body 21 is sleeved on the hub body 11, and the two cooperate with each other to provide key support for the vehicle's driving. At the same time, pay attention to let the rubber plate 24 be accurately sleeved on the hub body 11 and stuck in the second limiting groove 13 to achieve the limiting and buffering effect on the bearing body 21. Then, install the sound-absorbing sleeve 22 in the first limiting groove 12 so that it is tightly sleeved on the hub body 11, located between the hub body 11 and the bearing body 21, and effectively absorb the noise generated by the shaking of the bearing. For the buffer component, first sleeve the mounting ring 31 on the hub body 11 and fix it firmly with screws. Then let the support ring 32 be located on one side of the mounting ring 31 and contact the bearing body 21, and connect it with the connecting rod 34 and other connecting parts through the slider 33. Ensure that the slider 33 can slide smoothly in the slide groove 35, and achieve elastic buffering effect through the sliding rod 36 and the spring 37, and use the limiting nut to limit the moving range of the slider 33. Then, the fixed valve 23 is put on the hub body 11, and the fixing rod 16 is inserted into the fixing through hole 14 and the fixing groove 15 to achieve the firm fixation of the components. Finally, the sound-absorbing louvers 17 in the hub body 11 are used to further improve the sound absorption effect, ensuring the quietness, stability and comfort of the vehicle during driving. During use, the status of each component should be checked regularly to ensure its normal operation. If damaged, it should be repaired or replaced in time.

[0028] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
