Description

Technical Field

[0001] The utility model relates to the field of hubs, in particular to a cost-reduced hub. Background Art

[0002] The hub is an important component of a bicycle wheel. Located in the center of the wheel, it is responsible for connecting and supporting the tire and allowing the wheel to rotate. The name hub comes from the decorative patterns often seen in its early designs, but now refers more to its functional structure.

[0003] According to Chinese Patent Publication No. CN216545534U, a one-way transmission hub structure and bicycle are disclosed. The hub structure comprises a modular hub assembly, a ratchet assembly, and a freehub assembly. The freehub assembly is assembled with the ratchet assembly via a first engagement mechanism, and the ratchet assembly engages with the hub assembly via a second engagement mechanism. The ratchet assembly is a one-way bearing structure comprising a ratchet seat and a ratchet sleeve. The ratchet seat is equipped with several rolling elements and springs supporting the corresponding rolling elements. The ratchet sleeve covers the ratchet seat, all springs, and rolling elements therein. Each spring compresses the corresponding rolling element, ensuring that it maintains contact with the ratchet seat and ratchet sleeve. The one-way transmission hub structure of the utility model adopts a modular design, and the maintenance and care of the components are convenient and quick. In addition, the ratchet assembly uses rolling elements instead of the claw-type structure to make the rotation almost silent, the engagement is close to zero degrees at all times, and the transmission force is output in real time with low resistance. The bicycle using this mechanism has no pauses and is silent. However, the hub in the hub currently has the problems of material waste and long processing time during the processing. In addition, when locking the end cap at one end, the locking force is stretched by the end cap on one side, which is prone to uneven force. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 5 , the utility model provides two technical solutions, specifically including the following embodiments:

[0025] Example 1:

[0026] A cost-reducing hub comprises an integrated hub 1, a hub shell 2 is provided on the outside of the integrated hub 1, an axial thread 3 is provided at both ends of the interior of the hub shell 2, a hub end cover 5 and a freehub end cover 7 are respectively provided at both ends of the hub shell 2, the tire is mounted on the wheel, and the hub is assembled to the center of the wheel, the hub end cover 5 and the freehub end cover 7 are respectively connected to the integrated hub 1 and locked by threads, one end of the hub end cover 5 and the freehub end cover 7 are respectively fixedly connected with a first threaded platform 6 and a second threaded platform 8, the integrated hub 1 is respectively located inside the hub end cover 5 and the freehub end cover 7, a limiting ring 9 is fixedly connected inside the hub shell 2, and a first bearing 10, a second bearing 11, a third bearing 12 and a fourth bearing 13 are respectively engaged and connected inside the hub shell 2. When the wheel rotates, the integrated hub 1 drives the connecting plate 4 and the freehub end cover 7 to rotate, and the first bearing 10, the second bearing 11, the third bearing 12 and the fourth bearing 13 support the wheel and reduce rotational resistance, thereby realizing free rotation of the wheel.

[0027] During operation, the tire is mounted on the wheel, and the hub is assembled to the center of the wheel. The hub end cover 5 and the freehub end cover 7 are respectively connected to the integrated hub 1 and locked by threads. When the wheel rotates, the integrated hub 1 drives the connecting plate 4 and the freehub end cover 7 to rotate. The bearing supports the wheel and reduces the rotational resistance, thereby realizing the free rotation of the wheel. The threaded connection between the hub end cover 5 and the freehub end cover 7 firmly locks the integrated hub and the hub shell to ensure that the hub will not loosen during high-speed rotation. The hub and the axle are designed as one, and the small end face and the large end face are connected, which effectively reduces the amount of material required for the hub, reduces the material cost, and shortens the processing time. Locking screws are set at both ends to ensure uniform locking force at both ends, which improves the stability and reliability of the hub. A step is designed on the axle to replace the role of the sleeve, which simplifies the assembly process and reduces production costs. By optimizing the axle structure, eliminating the sleeve and simplifying the assembly process, the overall cost of the hub is effectively reduced and production efficiency is improved. The integrated axle design improves the strength and rigidity of the axle, making the hub more sturdy and durable. At the same time, the uniform locking force ensures the stability and reliability of the hub and improves the overall performance of the product. By optimizing the structure and materials, the cost of the hub is effectively reduced, the production efficiency is improved, and the performance of the product is guaranteed. It has broad application prospects.

[0028] Example 2:

[0029] On the basis of embodiment 1, one end of the outer side of the integrated hub 1 is provided with a step 14, and one end of the outer side of the hub shell 2 is symmetrically fixedly connected with a connecting plate 4, and the inner parts of the connecting plate 4 and the hub end cover 5 are circular and have holes. The inner parts of the connecting plate 4 and the hub end cover 5 are both provided with holes, which are convenient for installation and maintenance, and further improve the production efficiency. The hub end cover 5 and the first threaded platform 6 are threadedly connected to the hub shell 2 through the axial thread 3, and the freewheel base end cover 7 and the second threaded platform 8 are threadedly connected to the hub shell 2 through the axial thread 3. The threaded connection of the hub end cover 5 and the freewheel base end cover 7 is used to firmly lock the integrated hub 1 and the hub shell 2 to ensure that the hub will not loosen during high-speed rotation. The second bearing 11, the third bearing 12, and the fourth bearing 13 are all engaged with the outer side of the integrated hub 1. The integrated hub 1, the hub shell 2, the hub end cover 5 and the freewheel base end cover 7 are all made of aluminum alloy. The use of aluminum alloy makes the hub lighter and stronger, meeting the use requirements of the hub;

[0030] When the wheel rotates, the integrated hub 1 drives the connecting plate 4 and the freehub end cover 7 to rotate, and the bearings 11, 12, and 13 support the wheel and reduce the rotational resistance, thereby realizing the free rotation of the wheel. The threaded connection between the hub end cover 5 and the freehub end cover 7 firmly locks the integrated hub 1 and the hub shell 2 to ensure that the hub will not loosen during high-speed rotation. By providing the step 14 and the connecting plate 4, the assembly process is simplified and the production efficiency is improved. At the same time, the use of aluminum alloy makes the hub lighter and stronger, meeting the use requirements of the hub.

[0031] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
