Description

Technical Field

[0001] This utility model relates to the field of motorcycle wheel hub technology, and in particular to an electric motorcycle wheel hub. Background Technology

[0002] The wheel rims of electric motorcycles provide a solid mounting base for the tires, ensuring a secure connection between the tires and the motorcycle, working together to withstand various road conditions and pressures during operation. Whether on a smooth highway or a rugged country road, the wheel rims must consistently maintain the correct shape and position of the tires to guarantee the stability of the electric motorcycle.

[0003] When an electric motorcycle is in motion, there may be various sharp objects on the road. When the tire runs over these sharp objects, they may penetrate the tire's rubber layer, causing a leak. Continuing to ride with a leaky tire means the wheel rim directly bears the impact force from the road surface. During vehicle operation, this impact force continuously acts on the wheel rim, potentially causing wear and deformation, or even rendering the wheel rim unusable, increasing vehicle repair costs. Utility Model Content

[0004] In order to reduce the possibility of wheel hub deformation and wear after tire leakage, this application provides an electric motorcycle wheel hub.

[0005] The electric motorcycle wheel hub provided in this application adopts the following technical solution:

[0006] An electric motorcycle wheel hub includes a hub housing, a rim, a support ring, and a drive component. The rim is disposed on the hub housing, and the support ring is slidably connected to the hub housing. The diameter of the support ring is larger than the diameter of the rim. The support ring is provided with a wear-resistant and shock-absorbing ring. The drive component is used to drive the support ring to slide. When a tire is mounted on the hub housing, the drive component drives the support ring to abut against the tire.

[0007] By adopting the above technical solution and setting a support ring, when the tire leaks air, the wear-resistant and shock-absorbing ring on the support ring can contact the road surface and replace the support function of the tire. This allows the wheel hub to maintain a relatively normal working state after the tire leaks air, reducing the possibility of wheel hub deformation and damage. Furthermore, by having the support ring abut against the tire, the position of the tire can be limited, reducing the possibility of circumferential displacement between the tire and the wheel hub shell.

[0008] Preferably, it further includes a support member for connecting the support ring and the hub housing. The support member includes a connecting ring and a plurality of support rods. The connecting ring is slidably connected to the hub housing. The two ends of the plurality of support rods in the length direction are respectively disposed on the support ring and the connecting ring. The driving member is used to drive the movement of the connecting ring.

[0009] By adopting the technical scheme, when the support ring is subjected to force from the tire or the road surface, the force can be evenly dispersed to the hub shell through the support rods. The deformation or damage of the support ring due to the pressure alone is reduced, and the force burden of the hub shell is also reduced, so that the entire hub structure is more stable.

[0010] Preferably, the driving member comprises a threaded ring coaxially and rotatably connected to the support ring, and the threaded ring is threadedly connected to the hub shell.

[0011] By adopting the technical scheme, when the threaded ring rotates, the axial position of the threaded ring on the hub shell moves, and since the support ring is coaxially and rotatably connected to the threaded ring, the support ring can be moved. The structure of the threaded ring is relatively simple, easy to manufacture and install, and does not occupy too much space, and the sliding driving function of the support ring is achieved. When the support ring is damaged, the overall structure of the support ring is also easy to replace.

[0012] Preferably, a plurality of limiting grooves are formed in the hub shell, and the plurality of limiting grooves correspond to the plurality of support rods respectively, and the plurality of support rods are slidably connected in the corresponding limiting grooves.

[0013] By adopting the technical scheme, the limiting grooves provide guidance and limiting for the sliding of the support rods. The support rods can drive the support ring to slide smoothly along a predetermined track, ensuring that the support ring abuts against the tire accurately, and reducing the possibility of circumferential displacement between the support ring and the hub shell during vehicle driving. Through the cooperation of the limiting grooves and the support rods, the pressure borne by the support ring can be evenly dispersed to the hub shell. The structural strength of the hub as a whole is enhanced, and the service life of the hub is prolonged.

[0014] Preferably, a plurality of heat dissipation fins are arranged on the hub shell, and a limiting groove is naturally formed between any two adjacent heat dissipation fins.

[0015] By adopting the technical scheme, the heat dissipation fins increase the heat dissipation area of the hub shell, and the limiting grooves naturally formed between the adjacent heat dissipation fins provide accurate guidance and positioning for the support rods.

[0016] Preferably, a plurality of bolts are further arranged, and one end of each of the plurality of bolts is arranged through the threaded ring and threadedly connected to the connecting ring.

[0017] By adopting the technical scheme, the threaded ring and the connecting ring are tightly connected together through the bolts, so that they form a stable overall structure. The possibility of relative displacement between the threaded ring and the connecting ring is reduced, and the threaded ring is limited. Through the threaded connection of the bolts, the installation and disassembly between the threaded ring and the connecting ring are facilitated, and the convenience and efficiency of maintenance are improved.

[0018] Preferably, the outer surface of the wear-resistant shock-absorbing ring is provided with anti-slip texture.

[0019] By adopting the above technical solution, the anti-slip pattern can increase the friction between the wear-resistant shock-absorbing ring and the inner surface of the tire, and improve the stability of the relative position between the tire and the rim.

[0020] The main technical effects of this utility model are reflected in the following aspects:

[0021] 1. By setting a support ring, when the tire leaks air, the wear-resistant and shock-absorbing ring on the support ring can contact the road surface and replace the support function of the tire. This allows the wheel hub to maintain a relatively normal working state after the tire leaks air, reducing the possibility of wheel hub deformation and damage. Furthermore, by having the support ring abut against the tire, the position of the tire can be limited, reducing the possibility of circumferential displacement between the tire and the wheel hub shell.

[0022] 2. By incorporating support components, this utility model ensures that when the support ring is subjected to forces from the tire or road surface, these forces are evenly distributed to the wheel hub housing via the support rods. This reduces the risk of deformation or damage to the support ring due to individual pressure, and also alleviates the localized stress on the wheel hub housing, making the entire wheel hub structure more stable.

[0023] 3. This utility model, by setting a threaded ring, allows the threaded ring to move axially along the hub housing when it rotates. Since the support ring and the threaded ring are coaxially connected, the support ring can be moved. The threaded ring has a relatively simple structure, is easy to manufacture and install, and achieves the sliding drive function of the support ring without occupying too much space. When the support ring is damaged, the entire support ring structure can be easily replaced. Attached Figure Description

[0034] Referring to Figure 1 and Figure 4 , by arranging the support rings 3, when the tire is punctured, the wear-resistant shock-absorbing rings 5 on the support rings 3 can be in contact with the road surface, replacing the support function of part of the tire, so that the hub can still maintain a relatively normal working state after the tire is punctured, and the possibility of deformation and damage of the hub is reduced; and the support rings 3 abut against the tire, the anti-skid lines can increase the friction between the wear-resistant shock-absorbing rings 5 and the inner surfaces of the tire, the position of the tire can be limited, the possibility of circumferential displacement between the tire and the hub shell 1 is reduced, and the stability of the relative position between the tire and the hub is improved.
