Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle wheels, and particularly relates to an ultra-lightweight forged wheel. Background Art

[0002] The wheels of a motorcycle mainly consist of several parts, usually including a base that provides installation and support for the tire, a support tire that ensures the tire maintains a stable shape and position during driving, a connecting axle that is connected to the vehicle axle through a bearing, transmits the power of the motorcycle to the wheel, and propels the vehicle forward, and a load-bearing part that bears the weight of the motorcycle, including the weight of the vehicle itself as well as the weight of the rider and passengers.

[0003] Regarding the above problems, the wheel part is prone to wear, especially during high-intensity and long-time driving. The heat of the wheel axle and the vehicle itself is easily conducted to the wheel position. Scratches and deformations caused by friction and bumps are also likely to result in insufficient structural strength. Moreover, most of the existing wheel support structures are heavy and costly. When replacing them, it is not only troublesome, but the inertia generated by the heavier wheel support structure during driving is also relatively large, thus increasing fuel consumption and exerting pressure on the braking system.

[0004] Therefore, an ultra-lightweight forged wheel is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an ultra-lightweight forged wheel, which can solve the problems that the self-weight and strength of the existing motorcycle wheels are difficult to balance during use, and the replacement and maintenance costs are too high.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an ultra-lightweight forged wheel, including a wheel axle part, an enhancing part is arranged outside the wheel axle part, a supporting part is arranged outside the enhancing part, a wheel rim part is arranged outside the supporting part, an inflation groove is formed inside the wheel rim part, a hollowing groove is formed inside the enhancing part, and the wheel axle part, the enhancing part, the supporting part and the wheel rim part are integrally formed.

[0007] Preferably, the hollowing groove is completed by milling, and the supporting part is arranged in a hollow I-shaped.

[0008] Preferably, an inner hole is formed inside the supporting part, the number of the supporting parts is five, and the outer edge of the supporting part is arc-shaped.

[0009] Preferably, five mounting holes are formed at the rear side of the enhancing part, and a long groove is formed at the rear side of the wheel axle part.

[0010] Preferably, the side of the support part close to the wheel axle part is arranged from thick to thin towards the side close to the wheel rim part, and the connection part between the support part and the wheel rim part is widened.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In this application, a wheel axle part is provided to stably connect the structure to the vehicle wheel axle, and the strengthening part is cooperated to make the high-load part close to the wheel axle have sufficient strength, and it is not easy to be damaged due to the weakening of the structure caused by the self-heating of the structure or collision during long-term use. The support part and the wheel rim part are connected, and the hollow support part is supported by multiple columnar structures, which can not only improve the strength of the structure itself, but also effectively reduce the weight of the structure. The tire part is installed and fixed through the wheel rim part, and the air inlet of the tire part can extend out from the position of the air inflation groove, which is convenient for the air inflation operation. The setting of the hollow groove can further reduce the weight of the strengthening part, and at the same time, it can allow the air flow to pass through when the vehicle is running to take away the heat on the surface of the structure, playing an auxiliary heat dissipation effect. The structure is integrally designed, effectively reducing the material used, and also reducing the cost when it is severely worn and needs to be replaced. Moreover, the ultra-lightweight design reduces the weight of the vehicle structure, reduces the vehicle inertia, and thus reduces the fuel consumption and the pressure on the braking system to a certain extent.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1-5 , the utility model provides a technical solution:

[0021] An ultra-lightweight forged wheel comprises an axle portion 1, a reinforcement portion 2 is arranged on the outer side of the axle portion 1, a support portion 3 is arranged on the outer side of the reinforcement portion 2, a rim portion 4 is arranged on the outer side of the support portion 3, an air filling groove 5 is opened on the inner side of the rim portion 4, a hollow groove 6 is arranged on the inner side of the reinforcement portion 2, and the axle portion 1, the reinforcement portion 2, the support portion 3 and the rim portion 4 are integrally formed

[0022] In this embodiment: the wheel axle portion 1 is provided to firmly connect the structure and the wheel axle, and the reinforcement portion 2 is used to make the high-load part close to the wheel axle have sufficient strength, so that it is not easy to be damaged due to the temperature rise of the structure itself or the fragility of the structure caused by collision when used for a long time, and the support portion 3 and the wheel rim portion 4 are connected. The hollow support portion 3 and the support with multiple columnar structures can not only improve the strength of the structure itself, but also effectively reduce the counterweight of the structure and install and fix the tire portion through the wheel rim portion 4. The inflation port of the tire portion can extend from the position of the inflation groove 5 to facilitate the inflation action. The setting of the hollow groove 6 can further reduce the weight of the reinforcement portion 2, and at the same time, it can allow the air flow to pass through when the vehicle is driving to take away the heat on the surface of the structure, thereby playing an auxiliary heat dissipation effect. The structure is an integrated design, and effectively reduces the material used. When it is severely worn and needs to be replaced, it also reduces the cost. The ultra-lightweight design reduces the weight of the vehicle structure and reduces the vehicle inertia, thereby reducing fuel consumption and the pressure on the braking system to a certain extent.

[0023] Specifically, Figure 1 , Figure 3 , Figure 5 As shown, the hollow groove 6 is completed by milling, and the support portion 3 is set to be a hollow I-shape.

[0024] Specifically, Figure 2 As shown, an inner hole 7 is opened on the inner side of the support part 3, the number of the support parts 3 is five, and the outer edge of the support part 3 is set to be arc-shaped.

[0025] Specifically, Figure 2 and Figure 5 As shown, five mounting holes 8 are provided on the rear side of the reinforcement portion 2 , and a long slot 9 is provided on the rear side of the wheel axle portion 1 .

[0026] Specifically, Figure 3 As shown, the support portion 3 is arranged from thick to thin from the side close to the hub portion 1 to the side close to the rim portion 4, and the connection between the support portion 3 and the rim portion 4 is widened.

[0027] In this embodiment: by setting the milling processing hollow groove 6, the hollow groove can be processed meticulously and evenly after the structure is integrally formed, and at the same time, it has higher efficiency for mass processing. The I-shaped support part 3 has higher force strength and stability, and the hollow setting can also reduce the deadweight of the structure. The inner hole 7 opened inside the support part 3 assists in cooling and reducing the weight. The arc-shaped outer edge can more effectively resist the airflow, and the surface area of ​​the arc is relatively large, and the contact area with the air is also larger, which can cooperate to take away the heat from the surface of the structure. When subjected to radial load, the force can be evenly transferred to other parts of the structure, reducing the risk of damage to the support part 3 itself and surrounding components due to stress concentration. The installation hole 8 is set for installing the wheel shaft part 1 and the axle position. The long groove 9 opened is hollowed out at the position of the wheel shaft part 1 close to the wheel shaft to facilitate the heat dissipation of the wheel shaft. The position of the support part 3 close to the rim part 4 needs to bear the load, so widening can effectively improve the force strength. The connection between the support part 3 and the rim part 4 is widened to avoid disconnection or deformation at the structural connection.

[0028] Working principle: When in use, the axle part 1 and the wheel axle are installed through the installation hole 8, and the tire part is installed and fixed through the rim part 4. The inflation port of the tire part extends from the position of the inflation groove 5. The setting of the hollow groove 6 can further reduce the weight of the reinforcement part 2. At the same time, it can allow air flow to pass through when the vehicle is driving to take away the heat on the surface of the structure, thereby playing an auxiliary heat dissipation effect. During normal driving, the heat generated by the wheel axle will be conducted to the axle part 1, and the long groove 9 will be used for heat dissipation. When it is severely worn and needs to be replaced, it is limited by the integrated structural design and the materials used are less than the existing technology, which reduces the replacement and maintenance costs.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
