Description

Technical Field

[0001] This utility model belongs to the field of motorcycle wheel rim technology, and particularly relates to a spoked vacuum wheel rim. Background Technology

[0002] Currently, there are three main types of motorcycle rim structures: the first is a tubeless tire integral rim, the second is a tubeless tire spoked rim, and the third is a spoked rim with an inner tube.

[0003] Tubeless unibody rims are molded in one piece, typically made of 6-series aluminum alloy, which offers high rigidity, impact resistance, and tensile strength. Furthermore, because they lack an inner tube, they are less prone to punctures compared to unibody rims. However, the unibody structure lacks cushioning, making it less effective at absorbing road vibrations. This makes the tire and shock absorber more susceptible to damage, and they are more prone to deformation or breakage under significant impacts. Once damaged, the entire rim must be replaced, resulting in high repair costs. Additionally, due to their poor shock absorption and cushioning, they are unsuitable for off-road riding or riding on rough mountain roads.

[0004] Tubeless spoked rims retain the comfort of traditional spoked wheels while overcoming the safety risks associated with inner tubes. Most rims are made of 7-series aluminum alloy, which is strong, resilient, and lighter than tubeless one-piece rims. They are suitable for long-distance riding and offer excellent comfort. However, most spokes bear the stress on the rim edge, making this area relatively weak. They also require smaller diameter spokes, making them prone to breakage or even rim damage when encountering large potholes or steep inclines. Furthermore, they cannot withstand significant impacts.

[0005] Spoke-type rims are inexpensive to manufacture. The spoke holes are located in the thicker part of the rim wall in the middle, which helps to distribute impact force, provides a certain degree of elasticity, and has strong adaptability to terrain (it can adjust itself when encountering obstacles), making it suitable for off-road driving. Furthermore, minor damage doesn't require replacing the entire rim, resulting in low maintenance costs. However, because they must be fitted with inner tubes, they are more prone to punctures compared to tubeless rims. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this invention provides a spoked vacuum rim that can improve impact resistance and reduce the possibility of tire blowout.

[0007] The objective of this utility model is achieved through the following technical solution: A spoked vacuum rim, comprising a hub and a rim coaxially arranged, and further comprising: Several threaded sleeves are connected to the center of the wheel rim with uniform pipe threads along the circumference. Several caps, one end of which is respectively limited and connected to several threaded sleeves, and the other end of which protrudes into the threaded sleeves; Several caps are respectively placed on the outer ends of several threaded sleeves; Several spokes, one end of which is fixedly connected to the hub, and the other end of which passes outward through the hub and is coaxially threaded to several caps.

[0008] Furthermore, one end of each spoke is fixedly connected to both ends of the hub, one end of the hub is evenly fixedly connected to half of the spokes along the circumference, and the other end of the hub is evenly fixedly connected to the other half of the spokes along the circumference.

[0009] Furthermore, a first sealing layer is provided between the threaded sleeve and the wheel rim.

[0010] Furthermore, a second sealing layer is provided between the cap and the threaded sleeve.

[0011] Furthermore, the center of the wheel rim is evenly provided with several spoke recesses along the circumference, and the outer ends of several threaded sleeves are respectively connected to the inner ends of several spoke recesses by pipe threads. The inner end of the cap is coaxially threaded to the inner end of the threaded sleeve, and the outer end of the cap is located inside the outer end of the spoke recess.

[0012] Furthermore, the outer end of the threaded sleeve is coaxially provided with a first threaded hole, and the inner end of the cap is threadedly connected to the first threaded hole.

[0013] Furthermore, the inner end of the threaded sleeve is coaxially provided with a connecting hole that connects to the first threaded hole. The large end of the strip cap is located inside the first threaded hole, and the outer diameter of the large end of the strip cap is larger than the diameter of the connecting hole. The small end of the strip cap protrudes from the connecting hole, and the outer diameter of the small end of the strip cap is not larger than the diameter of the connecting hole.

[0014] Furthermore, a second threaded hole is coaxially provided inside the spoke cap, and the outer end of the spoke is coaxially threaded to the second threaded hole.

[0015] Furthermore, the inner end of the spoke is provided with an upsetting head for being limited by the hub. Furthermore, the spoked vacuum rim also includes an inner liner tube, bearings, and oil seals press-fitted onto the hub.

[0016] The beneficial effects of this utility model are as follows: Because the spokes are connected to the relatively thick part of the rim through the spoke cap and threaded sleeve, larger diameter spokes can be used, which greatly increases the rim's strength and thus improves its impact resistance. In addition, by connecting the threaded sleeve to the rim to seal it, the inner tube is not required, which helps reduce the possibility of tire blowout. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This utility model provides a spoked vacuum rim, such as Figure 1-7 As shown, it includes a hub 1 and a rim 5 coaxially arranged, the rim being made of 7-series aluminum alloy. The spoked tubeless rim also includes: Several threaded sleeves 4 are connected to the center of the wheel rim 5 with uniform pipe threads along the circumference. Several caps 3, one end of each cap 3 is respectively limited and connected to several threaded sleeves 4, and the other end of each cap 3 extends inward through the threaded sleeves 4; Several caps 6 are respectively placed on the outer ends of several threaded sleeves 4; Several spokes 2, one end of which is fixedly connected to the hub 1, and the other end of which passes outward through the hub 1 and is coaxially threaded to several caps 3.

[0021] Understandably, since the spokes 2 are connected to the relatively thick part of the rim 5 through the spoke cap 3 and the threaded sleeve 4, a larger diameter spoke 2 can be used, greatly increasing the stress on the rim 5 and thus improving its impact resistance. At the same time, this spoked tubeless rim has good elasticity and cushioning, allowing riders to obtain comfort and a good riding experience even on complex road surfaces. It is suitable for long-distance riding on ordinary roads as well as off-road riding on rugged mountain roads. In addition, by connecting the threaded sleeve 4 to the rim 5 through the pipe thread to seal the rim 5, it is easy to disassemble and does not require the installation of an inner tube, thus helping to reduce the possibility of tire blowout.

[0022] In addition, minor damage to the rim does not necessarily require the replacement of the entire rim, thus reducing maintenance costs; at the same time, this type of spoked vacuum rim is lighter than a one-piece rim.

[0023] In one embodiment, one end of the spokes 2 is respectively limited and connected to both ends of the hub 1, one end of the hub 1 is uniformly limited and connected to half of the spokes 2 along the circumferential direction, and the other end of the hub 1 is uniformly limited and connected to the other half of the spokes 2 along the circumferential direction.

[0024] In one embodiment, a first sealant layer is provided between the threaded sleeve 4 and the wheel rim 5; specifically, when the threaded sleeve 4 is connected to the wheel rim 5 by pipe thread, an appropriate sealant is applied to the outside of the threaded sleeve 4 to form a first sealant layer between the threaded connection structure of the threaded sleeve 4 and the wheel rim 5.

[0025] It should be noted that this configuration allows the threaded sleeve 4 and the wheel rim 5 to meet certain torque requirements, providing stronger impact resistance and good sealing performance.

[0026] In one embodiment, a second sealing layer is provided between the cap 6 and the threaded sleeve 4.

[0027] Specifically, when the cap 6 is placed on the threaded sleeve 4, an appropriate removable sealant is applied to the inside of the cap 6 or the threaded sleeve 4 to form a second sealing layer between the cap 6 and the threaded sleeve 4.

[0028] In one embodiment, a plurality of spoke 2 recesses are uniformly arranged circumferentially in the middle of the wheel rim 5, and the outer ends of a plurality of threaded sleeves 4 are respectively connected to the inner ends of the plurality of spoke 2 recesses by pipe threads. The inner end of the cap 6 is coaxially threaded to the inner end of the threaded sleeve 4, and the outer end of the cap 6 is located inside the outer end of the spoke 2 recess.

[0029] It should be noted that the recesses of two adjacent spokes 2 should face the two ends of the hub 1 respectively, so that half of the spokes 2 can be connected to one end of the hub 1 and the other half of the spokes 2 can be connected to the other end of the hub 1.

[0030] In one embodiment, such as Figure 6 and Figure 7 As shown, the outer end of the threaded sleeve 4 is coaxially provided with a first threaded hole 401, and the inner end of the cap 6 is threadedly connected to the first threaded hole 401; the inner end of the threaded sleeve 4 is coaxially provided with a connecting hole 402 that connects to the first threaded hole 401, the large end of the strip cap 3 is located inside the first threaded hole 401, the outer diameter of the large end of the strip cap 3 is larger than the diameter of the connecting hole 402, and the small end of the strip cap 3 passes through the connecting hole 402, the outer diameter of the small end of the strip cap 3 is not larger than the diameter of the connecting hole 402.

[0031] Understandably, this design allows the cap 6 to be threaded onto the outer end of the threaded sleeve 4, meaning that the cap 6 can be installed and removed by simply turning it, which also makes it convenient to remove the cap 6 to replace the strip cap 3.

[0032] It should be noted that the outer end of the cap 6 is provided with an internal hexagonal hole so that the cap 6 can be turned by an internal hexagonal wrench.

[0033] In one embodiment, such as Figure 4 , Figure 5 and Figure 7 As shown, a second threaded hole 301 is coaxially provided inside the spoke cap 3, and the outer end of the spoke 2 is coaxially threaded to the second threaded hole 301 so as to coaxially thread the outer end of the spoke 2 to the spoke cap 3.

[0034] It should be noted that the outer end of the second threaded hole 301 can be coaxially provided with a hole body so that the spokes 2 can extend outward, thereby improving the adjustment margin.

[0035] It should be noted that the outer side of the cap 3 is provided with a turning part 302 for easy turning with a wrench, so that the cap 3 can be turned for adjustment.

[0036] In one embodiment, such as Figure 2 and Figure 4 As shown, the inner end of the spoke 2 is provided with an upsetting head 201 for being limited by the hub 1.

[0037] It should be noted that the size of the upsetting head 201 should be larger than the corresponding hole on the hub 1.

[0038] In one embodiment, such as Figure 1-3 As shown, the spoked vacuum rim also includes an inner liner tube 9, a bearing 8, and an oil seal 7, which are press-fitted onto the hub 1.

[0039] The installation process of this utility model is as follows: The bearing 8, inner liner tube 9 and oil seal 7 are press-fitted onto the hub 1; Screw the outer end of the threaded sleeve 4 into the inner end of the corresponding groove hole of the strip cap 3 on the wheel rim 5 using sealant; Pass the outer end of spoke 2 through hub 1, and apply anti-jamming agent to the outer end of spoke 2; Insert the spoke cap 3 into the threaded sleeve 4, and make the small end of the spoke cap 3 pass through the threaded sleeve 4 and thread it to the outer end of the spoke 2. Then use a wrench to adjust the spoke 2, spoke cap 3 and wheel rim 5 to the qualified state. After applying removable sealant to the inner end of the cap 6, screw it into the first threaded hole 401 of the threaded sleeve 4; The motorcycle axle is mounted on the bearing 8 of the wheel hub 1 to enable wheel rotation.
