[0029] Structure description: sheet type wheel hub 1: sheet type wheel hub 1 is the main part of the hub, and the outer part is cylindrical. This shape design meets the installation and use requirements of the hub on the vehicle, and can ensure the stable cooperation between the hub and the tire. The inner part of the sheet type wheel hub 1 is provided with a hole slot, which provides a space basis for the installation of other components. At the same time, the outer part is provided with a plurality of heat dissipation holes 2, which can effectively increase the heat dissipation area and dissipate heat in time during the operation of the hub, preventing the hub from affecting the performance and service life due to overheating.

[0030] Heat dissipation hole 2: the heat dissipation hole 2 is distributed on the outer surface of the sheet type wheel hub 1, which mainly promotes air circulation and realizes the heat dissipation function of the hub. During the driving of the vehicle, the hub will generate heat due to friction and other reasons. The heat dissipation hole 2 enables air to form a convection between the inside and outside of the hub, quickly dissipating heat and keeping the hub within a suitable working temperature range.

[0031] Sliding ring 3: the sliding ring 3 is arranged in the inner part of the sheet type wheel hub 1, and the inner part is provided with a hole for the installation and sliding of the connecting column 4 and other components. The sliding ring 3 plays a role in supporting and guiding the movement of the connecting column 4 and other components, ensuring the accuracy and stability of the relative movement between the components of the hub.

[0032] Connecting column 4: the connecting column 4 is slidably connected in the inner part of the sliding ring 3, and is an important part of the disassembly assembly. The outer part of the connecting column 4 is sleeved with a spring 12, and the end close to the spring 12 is fixedly connected with a connector. The inner part of the connector is fixedly connected with a resisting column 11. The connecting column 4 realizes the connection and disassembly function of the hub components through the cooperation of the spring 12 and the resisting column 11. When installing, the resisting column 11 can abut against other components to fix the hub structure; when disassembling, the spring 12 is compressed by pushing the connecting column 4, so that the resisting column 11 is separated from the abutment with other components, thereby realizing quick disassembly.

[0033] The hoop ring 5 is mounted inside the sliding ring 3, and a plurality of rollers 9 are fixedly connected to the inner center of the hoop ring 5. The hoop ring 5 functions to realize relative sliding, buffer impact force, and reduce wear between components when the hub is subjected to external force through the cooperation of the rollers 9 and other components. Meanwhile, the presence of the hoop ring 5 enhances the overall integrity and stability of the hub structure.

[0034] The fixed ring 6 is fixedly connected to the inside of the sliding ring 3, and a groove 7 is formed on the outer surface of the fixed ring 6. The groove 7 is in sliding connection with the rollers 9 inside the hoop ring 5, and the fixed ring 6 provides a sliding track for the rollers 9 to ensure the smoothness of the sliding of the hoop ring 5 inside the sliding ring 3. In addition, the outer end of the fixed ring 6 is fixedly connected with a receiving column 14, and a rubber ring 15 is sleeved on the receiving column 14 for connection and shock absorption. The inner part of the fixed ring 6 is also provided with an interface 2 which cooperates with the interface 1 of other components to realize the tight connection between components.

[0035] The groove 7 is formed on the outer surface of the fixed ring 6, and its shape and size are matched with the rollers 9 to provide a sliding track for the rollers 9. The rollers 9 roll in the groove 7 to convert the sliding friction between the hoop ring 5 and the fixed ring 6 into rolling friction, thereby reducing the friction resistance and improving the flexibility of the relative movement between the hub components.

[0036] The protrusion 8 is fixedly connected to the bottom of the fixed ring 6, and its outer part is in sliding connection with the rollers 9 inside the hoop ring 5. The cooperation of the protrusion 8 and the rollers 9 further guides the sliding direction of the hoop ring 5, and also increases the contact area between the hoop ring 5 and the fixed ring 6 to improve the stability of the connection.

[0037] The roller 9 is a sphere fixedly connected to the inner center of the hoop ring 5. The roller 9 is in sliding connection with the protrusion 8 and the groove 7 on the fixed ring 6 to realize flexible sliding of the hoop ring 5 inside the sliding ring 3. During the operation of the hub, the roller 9 can effectively buffer and disperse external force, reduce wear between components, and improve the reliability of the hub.

[0038] The rubber ring 10 can be provided at some connection parts of the hub to play a sealing and shock-absorbing role. For example, it can prevent foreign matter from entering the inside of the hub, and at the same time absorb the vibration generated during the operation of the hub to improve the comfort of vehicle driving and the service life of the hub.

[0039] The abutting column 11 is fixedly connected to the inner joint of one end of the connecting column 4, and its outer part is a cylinder. The main function of the abutting column 11 is to abut with other components during the installation of the hub to realize the fixed connection between the hub components. When disassembling, the abutting column 11 is separated from the abutment with other components by pushing the connecting column 4, thereby realizing quick disassembly.

[0040] Spring 12: Spring 12 is sleeved on the outer end of connecting column 4, which provides elastic force for connecting column 4. When the hub is installed, spring 12 is in a natural state, so that abutting column 11 can tightly abut other components; when disassembled, push connecting column 4 to compress spring 12, so that abutting column 11 is disconnected. The presence of spring 12 ensures that connecting column 4 can be automatically reset and fixed during installation and disassembly.

[0041] Stop block 13: Stop block 13 is fixedly connected to the inner wall of connecting column 4 on both sides, and the outer end abuts the outer end of spring 12. The function of stop block 13 is to limit the compression stroke of spring 12, prevent spring 12 from being damaged due to excessive compression, and at the same time, stop block 13 also provides certain positioning and support for connecting column 4 during sliding.

[0042] Supporting column 14: Supporting column 14 is fixedly connected to the outer end of fixed ring 6, and rubber ring 2 15 is sleeved on the outside of supporting column 14. Supporting column 14 is mainly used to connect fixed ring 6 with other components, providing a connecting support point. Rubber ring 2 15 is sleeved on supporting column 14, which plays a role in shock absorption and sealing, can reduce the influence of vibration on the hub structure, and at the same time prevent foreign matter from entering the hub.

[0043] Rubber ring 2 15: Rubber ring 2 15 is sleeved on the outside of supporting column 14, which has good elasticity and sealing property. During the operation of the hub, rubber ring 2 15 can absorb vibration energy, reduce the transmission of vibration to the hub structure, and improve the stability of vehicle driving. At the same time, the sealing effect of rubber ring 2 15 can effectively prevent dust, moisture and other impurities from entering the hub, protecting the normal operation of internal components.

[0044] Usage instructions
