A quick-release wheel hub Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, specifically to a quick-release wheel hub. Background Technology
[0002] A motorcycle wheel hub is a metal component mounted on a motorcycle to support the tires and secure their position. It is typically made of metal, such as aluminum alloy, steel, or magnesium alloy, offering high strength and durability. The hub is usually cylindrical in shape, centrally mounted on the axle, and connects to the vehicle's suspension and braking systems.
[0003] Most existing wheel hubs suffer from unreasonable structures, resulting in excessive use of raw materials, which in turn leads to heavy wheel hubs and high production costs.
[0004] To address the aforementioned technical issues, CN213501638U discloses a motorcycle wheel hub that, through structural optimization, involves evenly distributing several recesses around the connecting surface, thereby saving raw material usage, reducing product weight, lowering production costs, and facilitating installation and relocation without compromising strength.
[0005] The existing technology still has the following shortcomings: the existing technology uses multiple sets of bolts in a ring array for fixing, but this method will make disassembly cumbersome, reduce the disassembly speed, and affect maintenance efficiency. Summary of the Invention
[0006] The purpose of this invention is to provide a quick-release wheel hub, which has the advantage of rapid disassembly. It uses a single main shaft bolt to connect and install the wheel hub to the motorcycle frame, which not only makes disassembly simple and fast, but also improves maintenance efficiency, thereby solving the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-release wheel hub, comprising a wheel hub body;
[0008] The wheel hub body is equipped with a quick-release mounting mechanism inside, and both ends of the mounting mechanism are equipped with a continuous lubrication oil injection mechanism.
[0009] The mounting mechanism includes a connecting component, a fixing component, and an adapter component. The connecting component is disposed inside the wheel hub body, the fixing component is disposed inside the connecting component, and the adapter component is disposed inside the connecting component.
[0010] The oil injection mechanism includes a storage component, a filling component, and an oil discharge component. The storage component is located outside the connecting component, the filling component is located on top of the storage component, and the oil discharge component is located at the bottom of the storage component.
[0011] Preferably, the connecting assembly includes a bushing, which is fixedly installed inside the hub body, and an inner shaft is installed inside the bushing.
[0012] Brake disc mounting sleeves are fixedly installed at both ends of the outer side of the bushing.
[0013] Preferably, the fixing component includes a shaft, the shaft is inserted through the inner shaft, and a nut is threaded to one end of the shaft.
[0014] Preferably, the adapter component includes a keyway, which is formed on the inner sidewall of the inner shaft, and a spline is fixedly installed on the outer side of the shaft.
[0015] Preferably, the storage component includes an oil ring tube, which is fixedly installed on the outside of the bushing, and the inside of the oil ring tube is provided with oil foam.
[0016] Preferably, the filling assembly includes an oil filling pipe connected to the top of the oil ring pipe, and the top of the oil filling pipe is threaded with an oil sealing plug.
[0017] Preferably, the oil draining assembly includes an oil drain pipe, which is connected to the inner wall of the oil ring pipe, and the oil draining end of the oil drain pipe is connected to an oil outlet.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. This utility model achieves the advantage of quick disassembly of the wheel hub through the setting of the installation mechanism. It uses a single main shaft bolt connection to fix the wheel hub and connect it to the motorcycle frame. This not only facilitates operation but also has high efficiency in disassembly and installation. Compared with the existing technology that uses multiple sets of bolt rods in a ring array, it achieves the purpose of quick disassembly and assembly.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] This utility model provides a quick-release wheel hub, including a wheel hub body 1;
[0029] The wheel hub body 1 is equipped with a quick-release mounting mechanism 2 inside, and both ends of the mounting mechanism 2 are equipped with a continuous lubrication oil injection mechanism 3.
[0030] The mounting mechanism 2 includes a connecting component, a fixing component, and an adapter component. The connecting component is located inside the hub body 1, the fixing component is located inside the connecting component, and the adapter component is located inside the connecting component.
[0031] By coordinating the connecting components, fixing components, and adapter components, the wheel hub can be quickly disassembled, simplifying the operation and improving maintenance efficiency.
[0032] The oil filling mechanism 3 includes a storage component, a filling component, and an oil draining component. The storage component is located outside the connecting component, the filling component is located on top of the storage component, and the oil draining component is located at the bottom of the storage component.
[0033] The combination of storage, filling, and draining components allows for temporary storage of lubricating oil, facilitating its filling and ensuring continuous lubrication without causing rust or jamming at rotating parts.
[0034] Preferred;
[0035] As shown in Figure 2, the connecting assembly includes a bushing 21, which is fixedly installed inside the hub body 1. An inner shaft 22 is installed inside the bushing 21, which serves to connect and support the hub body 1, while limiting the internal fasteners.
[0036] Both ends of the outer side of the bushing 21 are fixedly installed with brake disc mounting sleeves 4. The brake disc mounting sleeves 4 facilitate the direct installation of the brake disc to cooperate with the brake pads on the frame for braking operation when the motorcycle needs to stop while it is in motion.
[0037] As shown in Figure 2, the fixing component includes a shaft 24. The shaft 24 is inserted through the inner shaft 22. One end of the shaft 24 is threaded with a nut 25, which facilitates the direct installation and connection between the wheel hub body 1 and the motorcycle frame, improving the efficiency and speed of disassembly and installation. Compared with the existing technology that uses a ring array of six bolts for installation, it is more convenient and faster.
[0038] As shown in Figure 2, the adapter component includes a keyway 23, which is formed on the inner side wall of the inner shaft 22. A spline 26 is fixedly installed on the outer side of the shaft 24. The two are inserted into each other to achieve stability during connection and fixation, while the hub body 1 is not obstructed during rotation.
[0039] Figure 1 shows the installed state, while Figure 2 shows the disassembled state. When disassembly is required, fix the shaft 24 or the nut 25, and then rotate the shaft 24 or the nut 25. One is a fixed state and the other is to rotate it by a tool. Both can achieve single fixation or rotation by an external tool.
[0040] Once the rotating shaft 24 and nut 25 are separated and the threaded connection is released, the shaft 24 can be pulled directly. It will gradually detach from the inner shaft 22 and the motorcycle frame, and the spline 26 will disengage from the keyway 23. At this point, the wheel hub can be pulled down directly to remove it.
[0041] During installation, simply reverse the disassembly method described above. Insert the shaft 24 through the motorcycle shaft and the inner shaft 22 inside the wheel hub body 1, and ensure that the shaft 24 and the keyway 23 are compatible. Then, remove the nut 25 that was disassembled above and tighten the nut 25 and the shaft 24 with threads.
[0042] In summary, this wheel hub achieves the advantages of quick removal, using a single main shaft bolt connection to fix the wheel hub and connect it to the motorcycle frame, making operation simple and disassembly and installation highly efficient.
[0043] further;
[0044] As shown in Figure 4, the storage component includes an oil ring tube 31, which is fixedly installed on the outside of the bushing 21. An oil sponge 32 is provided inside the oil ring tube 31 to temporarily store oil so that oil can be added during the motorcycle's operation.
[0045] As shown in Figure 4, the filling assembly includes an oil filling pipe 33, which is connected to the top of the oil ring pipe 31. The top of the oil filling pipe 33 is threaded with an oil sealing plug 34, which facilitates the filling of oil when there is a lack of oil and achieves sealing after filling.
[0046] As shown in Figure 4, the oil drain assembly includes an oil drain pipe 35, which is connected to the inner wall of the oil ring pipe 31. The oil drain end of the oil drain pipe 35 is connected to an oil outlet 36, which allows oil to be drained during motorcycle operation and is located at the bearing, thereby achieving the purpose of lubrication.
[0047] Figure 4 shows a disassembly diagram. When oil needs to be added, rotate the oil seal plug 34 to disengage from the oil injection pipe 33. The two are connected by threads, so the disassembly and installation are simple. Tightening and loosening operations can be achieved by simply turning clockwise and counterclockwise.
[0048] When the oil is taken out, it is directly added into the oil ring tube 31 through the oil injection pipe 33 and will be absorbed by the oil cotton 32. When the filling is saturated, the filling is stopped, and then the sealing plug 34 is tightened to seal the filling port. When it is necessary to add oil to the rotating part, that is, the bearing installation part, some oil will enter the drain pipe 35 according to the hub body 1 and then be discharged to the bearing through the micro-injection oil outlet 36 to complete the oil filling. Due to the limitation of the oil outlet 36, each filling is a small amount. At the same time, the amount thrown by centrifugal force is limited, so there is no need to worry about it being directly discharged. The oil can be replenished regularly and quantitatively at intervals.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
