Description

Technical Field

[0001] The utility model relates to the technical field of bicycle hub lubrication, in particular to a bicycle hub which is easy to lubricate and maintain. Background Art

[0002] Bicycle hubs, commonly known as "hub barrels", are available in two types: iron hubs and aluminum hubs. Iron hubs are the hubs for ordinary bicycles ridden at home, while aluminum hubs are generally higher-end hubs, used as hubs for mountain bikes, performance bikes, road bikes, etc. Bicycle hubs connect the spokes and axles, and are a relatively important part of a bicycle. The average speed of riding a bicycle is directly affected by the quality of the hub, because the whole looks like a hub being struck when standing up, hence the name "hub".

[0003] Lubrication is a technical measure that can improve the friction state of the friction pair to reduce frictional resistance and slow down wear. Lubrication is generally achieved through lubricants. In addition, lubricants also have functions such as rust prevention, vibration reduction, sealing, and power transmission. Making full use of modern lubrication technology can significantly improve the performance and life of the machine and reduce energy consumption.

[0004] Please refer to the patent publication CN217574710U for a bicycle hub that is easy to lubricate and maintain. The patent states that "most existing bicycle hubs are sealed structures, and the long-term relative rotation between the hub outer shaft and the hub inner shaft will consume the internal grease oil. When replenishing the grease oil, the hub needs to be disassembled as a whole to replenish the internal grease oil, making the traditional bicycle hub extremely inconvenient to lubricate and maintain." In addition, the existing technology is prone to uneven lubrication when lubricating the bicycle hub, and some parts cannot be lubricated, so the practicality and flexibility are low. Therefore, this application proposes another technical solution to solve this problem. Utility Model Content

When the hub inner shaft 9 needs to be lubricated, firstly open the sealing cover 601 from the top of the oil inlet pipe 6, and then pour the lubricating oil into the interior of the upper bracket 2 through the oil inlet pipe 6, and the lubricating oil passes through the oil inlet pipe 6. The oil pipe 6 enters the interior of the infusion pipe 7, and the lubricating oil flows into the inner side of the guide pattern 10 through the infusion pipe 7 and spreads and flows through the guide pattern 10. The guide pattern 10 can deliver the lubricating oil to various parts of the hub inner shaft 9, which is convenient for all-round lubrication of the hub inner shaft 9 and greatly improves the lubrication efficiency. During the operation of the entire device, the lubricating oil can be continuously applied to the outer side of the hub inner shaft 9 for lubrication. The liquid outlet pipe 12 can be opened, and the lubricating oil can pass through the sponge pad 11 and enter the interior of the liquid outlet pipe 12 for recovery, thereby improving the use efficiency of the lubricating oil and increasing the practicability of the device.
