Description

Technical Field

[0001] This utility model relates to a novel flower drum. Background Technology

[0002] In the cycling industry, the hub is the core component of the wheelset, and its structural strength and lubrication performance directly affect the smoothness of riding and its service life. Traditional hubs typically use a one-piece shell or a split design connected by threads / bolts. This structure has the following drawbacks in maintenance: 1) Inconvenient disassembly and assembly: Repairing the internal bearings or lubrication system of the hub often requires completely disassembling the entire hub, sometimes even requiring the use of special tools, which is cumbersome and time-consuming; 2) Difficult lubrication maintenance: The oil injection channels of traditional hubs are usually independent of the shell structure, making it difficult for lubricating grease to be evenly distributed to key friction points, and long-term use can easily lead to lubrication failure due to oil passage blockage. Therefore, there is an urgent need for a new hub structure that can achieve quick disassembly and assembly and convenient maintenance, thereby improving maintenance efficiency and extending the hub's service life. Utility Model Content

[0003] This invention provides a novel flower drum that can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A novel hub includes a hub body, a mounting end, a shaft, and a double-layer shell structure disposed in the middle of the hub body. The double-layer shell structure includes a first shell and a second shell, which are detachably connected by a snap-fit ​​mechanism. Both the first and second shells are provided with internal reinforcing ribs, and an oil injection channel is provided between the first and second shells and the inner cavity of the hub body.

[0006] The beneficial effects of this utility model are:

[0007] (1) The hub of this utility model achieves quick assembly and disassembly through a double-layer shell structure and snap-fit ​​mechanism, significantly simplifying the maintenance process; the internal reinforcing ribs reduce the overall weight while ensuring structural strength; the oil injection channel directly connects to the inner cavity, ensuring that the lubricating oil reaches the key friction parts efficiently, thereby extending the maintenance cycle and improving the lubrication effect. This integrated design not only improves the durability and ease of maintenance of the hub, but also optimizes riding performance, achieving a synergistic improvement in lightweight, high strength and long-lasting lubrication.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0018] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] Reference Figure 1-4 As shown, a novel hub includes a hub body 10, a mounting end 20, a shaft core 70, and a double-layer shell structure disposed in the middle of the hub body 10; the mounting end 20 of the hub body 10 is provided with a pad 30, and the mounting end 20 is provided with a spoke opening 50, which is offset from the double-layer shell structure to avoid stress concentration.

[0020] The double-shell structure includes a first shell 40 and a second shell 40-0, which are detachably connected by a snap-fit ​​mechanism. Both the first shell 40 and the second shell 40-0 have internal reinforcing ribs 402. An oil injection channel 404 connects the first shell 40 and the second shell 40-0 to the inner cavity 60 of the hub body 10. The oil injection channel 404 includes an inclined portion 4040, which is inclined towards the inner cavity 60 of the hub body 10 to optimize the flow path of the lubricating oil. The lubricating oil flows naturally into the inner cavity 60 along the inclined channel, avoiding blockages in horizontal oil passages, and the oil directly covers the critical friction surfaces of the bearing, reducing dry friction loss.

[0021] Both the first shell 40 and / or the second shell 40-0 have an inner shell 400, which is integrally formed with the inner reinforcing ribs 402. The inner reinforcing ribs 402 are distributed in a grid pattern to reduce weight while ensuring structural strength. Specifically, the reinforcing ribs 402 are topologically optimized and densely arranged in critical stress areas (such as around the spoke opening 50). The grid structure reduces weight by 20% to 30% compared to a solid shell while maintaining torsional strength. The gaps between the ribs form air circulation channels, reducing the risk of bearing overheating.

[0022] The snap-fit ​​mechanism includes a splicing rod 40-1 disposed on the second housing 40-0 and a snap-fit ​​groove 40-2 disposed on the splicing rod 40-1; the snap-fit ​​mechanism also includes a mounting groove 406 disposed on the first housing 40, an elastic element 408 disposed on the mounting groove 406, and a plug-in 410 connected to the elastic element 408; when the first housing 40 and the second housing 40-0 are assembled, the plug-in 410 is compressed by the elastic element 408 and elastically inserted into the snap-fit ​​groove 40-2 to achieve quick installation; wherein, the plug-in 410 includes a clearance portion 4100, so that the plug-in 410 can be quickly disengaged from the snap-fit ​​groove 40-2.

[0023] The first shell 40, the second shell 40-0, and the inner shell 400 are all made of aluminum alloy or titanium alloy. Among them, the aluminum alloy shell is more than 40% lighter than the steel shell, and the titanium alloy is more corrosion resistant.

[0024] Working principle: The hub body 10 adopts a modular design through a double-shell structure, with a first shell 40 and a second shell 40-0. The two are quickly assembled and disassembled through a snap-fit ​​mechanism. The snap-fit ​​groove 40-2 on the splicing rod 40-1 cooperates with the elastic element 408 and the plug 410 in the mounting groove 406 of the first shell 40. The plug 410 is inserted into the snap-fit ​​groove 40-2 by elastic compression to lock it in place. The clearance part 4100 facilitates quick disassembly. The double-shell has a grid-like distribution of internal reinforcing ribs 402 and an integrally formed inner shell 400, which reduces weight while ensuring structural strength. The oil injection channel 404 efficiently introduces lubricating oil into the inner cavity 60 through the inclined part 4040 to ensure lubrication effect. The pad 30 of the mounting end 20 reduces vibration, while the staggered layout of the spoke opening 50 and the shell avoids stress concentration. The whole is made of aluminum alloy or titanium alloy to balance lightweight and durability, and finally achieves the integrated functions of convenient maintenance, long-term lubrication and high rigidity.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
