Description

Technical Field

[0001] The utility model relates to the technical field of hubs, in particular to a carbon fiber rear disc wheel hub. Background Art

[0002] The bicycle hub refers to the drum-shaped object in the center of the wheel, which is equipped with bearings and axles. It is connected to the frame through the axles and connected to the rims through spokes. It is the core component of the wheel set. The performance of the hub determines the performance of the wheel set system and whether it operates smoothly.

[0003] During the running of a bicycle, the inner shaft of the hub generates a lot of heat due to friction and rotation. However, the existing metal hub shell has limited thermal conductivity and cannot effectively and timely dissipate the heat, causing the temperature inside the hub to rise rapidly. Long-term high-temperature operation will not only affect the service life of the hub, but also pose a potential threat to the riding safety of the rider. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a carbon fiber rear wheel disc wheel hub, comprising a hub inner shaft, a hub shell is arranged on the outer side of the hub inner shaft, a freewheel base is rotatably connected to one side between the hub shell and the hub inner shaft, a brake pad is fixedly assembled on the other side between the hub shell and the hub inner shaft, a heat conducting ring plate is fixedly connected to the inside of the hub shell, heat conducting side plates are fixedly connected to both sides of the heat conducting ring plate, a heat conducting sleeve is fixedly connected to the inner wall of the heat conducting side plate, a heat transfer plate is fixedly connected to the outer side of the heat conducting ring plate, a side of the heat transfer plate away from the heat conducting ring plate penetrates to the outside of the hub shell and is fixedly connected to an external metal plate, a plurality of heat sinks are fixedly connected to the outer side of the external metal plate, a heat dissipation groove 1 and a heat dissipation groove 2 are respectively provided on both sides of the hub shell, a reinforcement layer is fixedly connected to the outer surface of the hub shell, the reinforcement layer comprises a carbon fiber layer and a wear-resistant coating, and the wear-resistant coating is applied to the inner wall of the carbon fiber layer.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The carbon fiber rear disc wheel hub constructs an efficient heat conduction path through the combined application of a heat-conducting ring plate, a heat-conducting side plate and a heat-conducting sleeve. The heat-conducting sleeve is directly mounted on and fixedly connected to the inner shaft of the hub, so that the heat generated by the inner shaft can be quickly and effectively transferred to the heat-conducting ring plate and the heat-conducting side plate through the heat-conducting sleeve, and then quickly dissipated to the outside through the heat transfer plate and the heat sink on the external metal plate. This design significantly improves the heat transfer efficiency, effectively reduces the temperature of the hub during operation, and prevents performance degradation or damage due to overheating, thereby ensuring the stability and durability of the hub.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-5The utility model provides a technical solution: a carbon fiber rear disc wheel hub, comprising a hub inner shaft 1, a hub shell 2 is arranged on the outer side of the hub inner shaft 1, a freewheel base 3 is rotatably connected to one side between the hub shell 2 and the hub inner shaft 1, a brake pad 4 is fixedly assembled on the other side between the hub shell 2 and the hub inner shaft 1, a heat conduction ring plate 10 is fixedly connected to the inside of the hub shell 2, heat conduction side plates 11 are fixedly connected to both sides of the heat conduction ring plate 10, and a heat conduction sleeve 15 is fixedly connected to the inner wall of the heat conduction side plate 11 A heat transfer plate 12 is fixedly connected to the outer side of the heat-conducting ring plate 10. The side of the heat transfer plate 12 away from the heat-conducting ring plate 10 penetrates to the outside of the hub shell 2 and is fixedly connected to an external metal plate 13. A plurality of heat sinks 14 are fixedly connected to the outer side of the external metal plate 13. Heat dissipation grooves 18 and 29 are respectively provided on both sides of the hub shell 2. A reinforcement layer 5 is fixedly connected to the outer surface of the hub shell 2. The reinforcement layer 5 includes a carbon fiber layer 6 and a wear-resistant coating 7. The wear-resistant coating 7 is applied to the inner wall of the carbon fiber layer 6.

[0016] The heat-conducting sleeve 15 is sleeved and fixedly connected to the hub inner shaft 1 , which can ensure that the heat generated by the hub inner shaft 1 is effectively conducted to the heat-conducting sleeve 15 .

[0017] The inner walls on both sides of the external metal plate 13 are fixedly connected to the outer wall of the hub shell 2, thereby enhancing the stability of the entire structure.

[0018] Dust-proof nets are fixedly installed at the outer sides of the heat dissipation slot 1 8 and the heat dissipation slot 2 9 to effectively prevent dust and debris from entering the heat dissipation slots.

[0019] The carbon fiber layer 6 is formed by weaving extremely fine carbon fiber bundles in a specific manner to form a carbon fiber cloth, which is then compounded with a resin matrix, and can improve the overall strength and rigidity of the hub shell 2 .

[0020] The wear-resistant coating 7 is a tungsten carbide coating, which enhances the wear resistance of the hub shell 2 and prolongs its service life.

[0021] Both sides of the inner shaft 1 of the hub are provided with mounting threads.

[0022] Working principle: During the operation of the hub, the inner shaft 1 of the hub will generate a large amount of heat due to friction and rotation. The heat received by the heat-conducting sleeve 15 is further transferred to the heat-conducting ring plate 10 through the heat-conducting side plate 11. Subsequently, the heat is transferred to the external metal plate 13 through the heat transfer plate 12. The external metal plate 13 has good thermal conductivity and can quickly disperse the heat to the heat sink 14 thereon. The design of the heat sink 14 increases the heat dissipation area and improves the heat dissipation efficiency, so that the heat can be dissipated into the air faster. The heat sink 14 on the external metal plate 13 exchanges heat with the air and releases the heat to the external environment. At the same time, the heat dissipation slot 1 8 and the heat dissipation slot 2 9 opened inside the hub shell 2 provide additional dissipation channels for the heat, further enhancing the heat dissipation effect.

[0023] In summary: the carbon fiber rear disc wheel hub, through the combined application of the heat-conducting ring plate 10, the heat-conducting side plate 11 and the heat-conducting sleeve 15, constructs an efficient heat conduction path. The heat-conducting sleeve 15 is directly sleeved and fixedly connected to the inner shaft 1 of the hub, so that the heat generated by the inner shaft can be quickly and effectively transferred to the heat-conducting ring plate 10 and the heat-conducting side plate 11 through the heat-conducting sleeve 15, and then quickly dissipated to the outside through the heat transfer plate 12 and the heat sink 14 on the external metal plate 13. This design significantly improves the heat transfer efficiency, effectively reduces the temperature of the hub during operation, and prevents performance degradation or damage caused by overheating, thereby ensuring the stability and durability of the hub. The dustproof net installed on the outside of the heat dissipation groove 1 8 and the heat dissipation groove 2 9 effectively prevents the entry of dust and debris, ensuring the unobstructed heat dissipation groove. This design avoids the problem of reduced heat dissipation efficiency caused by blockage of the heat dissipation groove, so that the hub can maintain efficient heat dissipation performance even in harsh environments.
