Description

Technical Field

[0001] This utility model belongs to the field of motorcycle wheel rim technology, and in particular relates to a motorcycle spoke-type 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 technology, this utility model provides a spoked vacuum rim for motorcycles, which 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 motorcycle spoked tubeless rim includes a hub and a rim coaxially arranged, and the motorcycle spoked tubeless rim also includes: Several grooves are provided on the circumferential side of the middle part of the wheel rim; Several caps, one end of each cap is respectively limited and connected in several grooves, and the other end of each cap extends inward through the grooves; 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 then coaxially threaded to several caps.

[0008] Furthermore, half of the grooves are provided circumferentially on one side of the center of the wheel rim, and the other half of the grooves are provided circumferentially on the other side of the center of the wheel rim.

[0009] Furthermore, one end of each of the two adjacent spokes is respectively positioned and connected to both sides of the hub; One side of the hub is circumferentially connected to half of the spokes, while the other half of the grooves are connected to the other half of the spokes by a spoke cap. The other half of the spokes are connected to the other half of the hub along the circumferential limit, and the grooves of the other half are connected to the other half of the spokes by the bar cap.

[0010] Furthermore, one end of the groove extends to the surface of one side of the middle of the wheel rim.

[0011] Furthermore, the groove is a T-shaped groove, with the large end of the cap moving to the bottom of the groove and the small end moving to the top of the groove.

[0012] Furthermore, the small end diameter of the cap is no greater than the top width of the groove, the large end diameter of the cap is no greater than the bottom width of the groove, and the large end diameter of the cap is greater than the top width of the groove.

[0013] Furthermore, a threaded hole is coaxially provided inside the spoke cap, and the outer end of the spoke is coaxially threaded to the threaded hole.

[0014] Furthermore, the inner end of the cap is provided with a screwing part.

[0015] Furthermore, motorcycle spoked vacuum rims also include inner liner tubes, bearings, and oil seals press-fitted onto the hub. Furthermore, the inner end of the spoke is provided with an upsetting head for being limited by 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, larger diameter spokes can be used, which greatly increases the rim's strength and thus improves its impact resistance. In addition, the grooves do not extend outwards from the rim, meaning that an inner tube is not needed, which helps reduce the possibility of a tire blowout. Attached Figure Description

[0020] This utility model provides a spoked vacuum wheel rim for motorcycles, such as Figure 1-6 As shown, the wheel includes a hub 1 and a rim 4 coaxially arranged, the rim 4 being made of 7-series aluminum alloy; the motorcycle spoked tubeless rim also includes: Several grooves 401 are provided on the middle side of the wheel rim 4 along the circumferential direction; Several caps 3, one end of each cap 3 is respectively limited and connected in several grooves 401, and the other end of each cap 3 extends inward through the grooves 401; 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 4 by the spoke cap 3, a larger diameter spoke 2 can be used, which greatly increases the stress on the rim 4 and thus improves its impact resistance. At the same time, this motorcycle spoked tubeless rim has good elasticity and cushioning, so that the rider can have a comfortable and 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, the grooves 401 do not extend outwards from the rim 4, that is, there is no need to install an inner tube, which helps to reduce the possibility of tire blowout.

[0022] The spoked vacuum rim of this motorcycle has grooves 401 machined on the rim 4. Each spoke cap 3 slides into the groove 401 and can be tightened after being turned and adjusted, making it relatively easy to disassemble. At the same time, minor damage to the rim does not require the replacement of the entire rim, thus helping to reduce maintenance costs. In addition, this spoked vacuum rim of the motorcycle is lighter than that of a one-piece rim.

[0023] It should be noted that the spoke cap 3 is located within the groove 401. By tapping the spoke cap 3 with a special tool, the spoke cap 3 can be dislodged from the groove 401 of the wheel rim 4 for easy removal.

[0024] In one embodiment, half of the grooves 401 are provided circumferentially on one side of the middle portion of the wheel rim 4, and the other half of the grooves 401 are provided circumferentially on the other side of the middle portion of the wheel rim 4.

The other half of the spokes 2 are connected to the other half of the hub 1 along the circumferential direction, and the other half of the grooves 401 are connected to the other half of the spokes 2 by the spoke caps 3.

[0026] Understandably, after the spokes 2 and the spoke caps 3 are tightened, the two ends of the spokes 2 are respectively limited and connected to different sides of the rim 4 and the hub 1, so that several spokes 2 are interlaced and connected between the rim 4 and the hub 1.

[0027] In one embodiment, one end of the groove 401 extends to the middle side surface of the rim 4 so that the rim cap 3 can be inserted into the groove 401 from the middle side of the rim 4.

[0028] In one embodiment, the groove 401 is a T-shaped groove, the large end of the strip cap 3 moves to the bottom of the groove 401, and the small end of the strip cap 3 moves to the top of the groove 401, so as to slide and adjust the position of the strip cap 3 within the groove 401.

[0029] Specifically, the small end diameter of the strip cap 3 is not greater than the top width of the groove 401, the large end diameter of the strip cap 3 is not greater than the bottom width of the groove 401, and the large end diameter of the strip cap 3 is greater than the top width of the groove 401.

[0030] In one embodiment, a threaded hole 301 is coaxially provided inside the spoke cap 3, and the outer end of the spoke 2 is coaxially threaded to the threaded hole 301 so as to coaxially thread the outer end of the spoke 2 to the spoke cap 3.

[0032] In one embodiment, the trailer spoked vacuum rim also includes an inner liner tube 5, a bearing 6, and an oil seal 7 press-fitted onto the hub 1.

[0033] In one embodiment, the inner end of the spoke 2 is provided with an upsetting head 201 for being limited by the hub 1.

[0034] It should be noted that the size of the upsetting head 201 should be larger than the corresponding hole on the hub 1.

[0035] The installation process of this utility model is as follows: The bearing 6, inner liner tube 5 and oil seal 7 are press-fitted onto the hub 1; Pass the outer end of the spoke 2 through the hub 1, apply anti-jamming agent to the outer end of the spoke 2 and screw it into the threaded hole 301 of the spoke cap 3; after screwing it in, leave about 1 / 4 of the thread length in the threaded hole 301. Slide the nut 3 into the corresponding groove 401 on the wheel rim 4; Use a wrench to adjust spokes 2, spoke caps 3, and rim 4 to the correct roundness and torque. The motorcycle axle is mounted on the bearing 6 of the wheel hub 1 to enable wheel rotation.
