Description

Technical Field

[0001] This utility model relates to the field of wheel rim technology, and in particular to a lightweight, high-strength integrated wheel rim for motorcycles. Background Technology

[0002] A one-piece motorcycle wheel rim is a ring-shaped component manufactured by integrating the rim, spokes, and hub mount into a single piece. As a core component of the motorcycle's running system, its main function is to connect the tire to the axle, support the weight of the motorcycle, and transmit driving torque. Specifically, the rim, as the mounting base for the tire, provides shape constraint and support to the tire through its ring structure, ensuring stable contact between the tire and the ground. The spokes connect the rim to the hub mount, evenly transmitting the weight of the motorcycle and driving force to the rim while also withstanding various impacts during driving. The hub mount, located at the center of the rim, connects to the motorcycle axle through axle holes and is fixed to components such as the braking system through bolt holes, enabling the rim's rotational movement.

[0003] Existing one-piece motorcycle wheels suffer from a significant deficiency in balancing lightweight design and high strength, making them unsuitable for the demands of high-performance motorcycles. Some wheels, in pursuit of lightweight design, excessively reduce the thickness of the spokes and rims, resulting in decreased structural strength and making them prone to deformation or even breakage under heavy loads or impacts. Conversely, wheels prioritizing strength often utilize a single, heavy material, leading to excessive overall weight and increasing the vehicle's unsprung mass, impacting acceleration, braking, and handling performance. These issues prevent existing one-piece wheels from simultaneously achieving lightweight design, high strength, and structural stability, thus limiting further improvements in motorcycle performance. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a lightweight, high-strength integrated wheel rim for motorcycles to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a lightweight, high-strength, one-piece motorcycle wheel rim, comprising an integrally formed rim, a plurality of Y-shaped spokes arranged in a circumferential array, and a hub mounting base. The inner side of the rim has a plurality of spoke connecting portions evenly distributed along the circumferential direction. The outer ends of the Y-shaped spokes are integrally formed with the corresponding spoke connecting portions. The inner ends of the Y-shaped spokes are integrally formed with the outer side wall of the hub mounting base. A weight-reducing groove is provided through the vertical portion of each Y-shaped spoke. A strip-shaped groove is provided through the two inclined support portions of each Y-shaped spoke. A plurality of linearly arranged first stiffening plates are fixedly connected inside the strip-shaped groove. Annular grooves are provided at both ends of the hub mounting base, and a circumferentially arranged second stiffening plates are fixedly connected inside the annular grooves.

[0007] Preferably, as described in any of the above embodiments, the rim is an annular closed structure and the rim is made of magnesium alloy.

[0008] Preferably, the Y-shaped spokes are made of carbon fiber reinforced composite material, as described in any of the above embodiments.

[0009] Preferably, in any of the above embodiments, the hub mounting base is made of high-strength aluminum alloy, and the hub mounting base has a shaft hole at its center for fitting a motorcycle wheel axle. A number of bolt holes for installing fastening bolts are evenly distributed along the circumferential direction on the outer side of the shaft hole.

[0010] Preferably, the outer wall of the wheel rim is provided with an annular reinforcing structure, and the annular reinforcing structure is integrally formed with the wheel rim.

[0011] Preferably, in any of the above solutions, the second stiffening plate is integrally formed with the wheel hub mounting seat and the annular groove, and the second stiffening plate is made of the same high-strength aluminum alloy material as the wheel hub mounting seat.

[0012] Preferably, in any of the above embodiments, the first stiffening plate is integrally formed with the Y-shaped wheel spoke, and the first stiffening plate is made of the same carbon fiber reinforced composite material as the Y-shaped wheel spoke.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. The wheel rim is made of magnesium alloy, significantly reducing weight while maintaining the strength of the annular closed structure. The Y-shaped spokes are made of carbon fiber reinforced composite material. The weight-reducing grooves in the vertical part and the strip grooves in the inclined support part reduce material usage to achieve weight reduction. The first stiffening plate in the strip groove is integrally formed with the Y-shaped spoke, enhancing the overall strength of the spoke. The wheel hub mount is made of high-strength aluminum alloy. The second stiffening plates in the annular grooves at both ends are integrally formed with the wheel hub mount, reducing the weight of the wheel hub while improving structural strength. The combination of magnesium alloy rim, carbon fiber reinforced composite Y-shaped spokes, and high-strength aluminum alloy wheel hub mount, through the reasonable combination of different lightweight and high-strength materials, avoids a decrease in strength while reducing overall weight. The weight-reducing grooves and strip grooves reduce material usage, while the first and second stiffening plates respectively strengthen the spokes and wheel hub mount, effectively solving the problem of balancing lightweight and high strength in existing wheel rims. This reduces the unsprung mass of the vehicle and improves acceleration, braking performance, and handling agility.

[0015] 2. The Y-shaped spokes are arranged in a circumferential array. The outer end is integrally formed with the spoke connection of the rim, and the inner end is integrally formed with the outer wall of the hub mount, forming a uniform force transmission path. The annular reinforcing structure of the outer wall of the rim is integrally formed with it, enhancing the rim's resistance to deformation. The second stiffening plate of the hub mount is arranged in a circumferential array, strengthening the structural strength of the connection between the hub and the spokes. The structural design of the Y-shaped spokes and their integral connection with the rim and hub mount ensures uniform transmission of vehicle weight and driving force, reducing stress concentration. The annular reinforcing structure improves the rim's resistance to deformation under tire pressure and road impact. The second stiffening plate enhances the strength of the connection between the hub mount and the spokes, preventing fatigue damage in this complex stress area. This solves the problems of poor stability and easy damage caused by unreasonable existing wheel rim structural design, extends the wheel rim's service life, and improves the smoothness and safety of motorcycle riding.

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0022] like Figures 1 to 4 As shown, a lightweight, high-strength one-piece motorcycle wheel rim includes an integrally formed rim 1, several Y-shaped spokes 2 arranged in a circular array, and a hub mounting seat 3. Several spoke connecting parts 4 are evenly distributed along the circumferential direction on the inner side of the rim 1. The outer end of the Y-shaped spoke 2 is integrally formed with the corresponding spoke connecting part 4. The inner end of the Y-shaped spoke 2 is integrally formed with the outer side wall of the hub mounting seat 3. A weight-reducing groove 5 is provided through the vertical part of each Y-shaped spoke 2. A strip-shaped groove 6 is provided through the two inclined support parts of each Y-shaped spoke 2. Several linear arrays of first stiffening plates 7 are fixedly connected inside the strip-shaped groove 6. Annular grooves 8 are provided at both ends of the hub mounting seat 3. Circular arrays of second stiffening plates 9 are fixedly connected inside the annular grooves 8.

[0023] As an optional technical solution of this utility model, the rim 1 is a closed annular structure. The rim 1 is made of magnesium alloy. The closed annular structure of the rim 1 can ensure its overall rigidity and effectively withstand the pressure of the tire and the impact force during driving. The use of magnesium alloy material can significantly reduce the weight of the rim while meeting the strength requirements, which is conducive to reducing the unsprung mass of the motorcycle and improving the handling performance and fuel economy of the vehicle.

[0024] As an optional technical solution of this utility model, the Y-shaped spoke 2 is made of carbon fiber reinforced composite material. The Y-shaped spoke 2 is made of carbon fiber reinforced composite material, which has the characteristics of high strength and lightweight. It can reliably transmit the force between the rim 1 and the hub mounting seat 3, and further reduce the overall weight of the wheel rim. At the same time, the carbon fiber material has good fatigue resistance, which can extend the service life of the spokes and adapt to the complex driving conditions of motorcycles.

[0025] As an optional technical solution of this utility model, the wheel hub mounting base 3 is made of high-strength aluminum alloy. The center of the wheel hub mounting base 3 is provided with a shaft hole 10 for fitting the motorcycle wheel axle. A number of bolt holes 11 for installing fastening bolts are evenly distributed along the circumferential direction on the outer side of the shaft hole 10. The wheel hub mounting base 3 is made of high-strength aluminum alloy, which achieves lightweight while ensuring the connection strength with the wheel axle. The central shaft hole 10 can accurately fit the motorcycle wheel axle to ensure the normal rotation of the wheel rim. The bolt holes 11 on the outer side of the shaft hole 10 provide a stable interface for the installation of components such as the braking system, ensuring the firmness and reliability of the connection of each component.

[0026] As an optional technical solution of this utility model, the outer wall of the rim 1 is provided with an annular reinforcing structure 12. The annular reinforcing structure 12 is integrally formed with the rim 1. The annular reinforcing structure 12 on the outer wall of the rim 1 is integrally formed with the rim 1, which can significantly enhance the structural strength and deformation resistance of the rim 1. During the motorcycle ride, it can better resist the impact from the road surface and the expansion force of the tire, reduce the deformation of the rim 1, and ensure the overall stability of the wheel rim.

[0027] As an optional technical solution of this utility model, the second stiffening plate 9 is integrally formed with the wheel hub mounting seat 3 and the annular groove 8. The second stiffening plate 9 is made of the same high-strength aluminum alloy as the wheel hub mounting seat 3. The integral formation of the second stiffening plate 9 with the wheel hub mounting seat 3 and the annular groove 8 and the use of the same high-strength aluminum alloy not only ensures the firmness of the connection between the second stiffening plate 9 and the wheel hub mounting seat 3, but also effectively enhances the structural strength of the wheel hub mounting seat 3, disperses the stress borne by the wheel hub mounting seat 3, and avoids damage due to excessive force during long-term use.

[0028] As an optional technical solution of this utility model, the first stiffening plate 7 is integrally formed with the Y-shaped wheel spoke 2. The first stiffening plate 7 is made of the same carbon fiber reinforced composite material as the Y-shaped wheel spoke 2. The first stiffening plate 7 and the Y-shaped wheel spoke 2 are integrally formed and made of the same carbon fiber reinforced composite material. This will not increase the weight of the connecting structure, but will also strengthen the inclined support of the Y-shaped wheel spoke 2, improve the bending resistance of the spoke, prevent the spoke from deforming or breaking under stress, and ensure the structural stability and service life of the spoke.

[0029] A lightweight, high-strength one-piece motorcycle wheel rim, the working principle of which is as follows:

[0030] 1): The rim 1 is made of magnesium alloy, which greatly reduces weight while ensuring the strength of the annular closed structure; the Y-shaped spoke 2 is made of carbon fiber reinforced composite material, and the weight-reducing groove 5 in its vertical part and the strip groove 6 in the inclined support part reduce the amount of material used to achieve weight reduction.

[0031] 2): The wheel hub mounting base 3 is made of high-strength aluminum alloy. The second stiffening plate 9 in the annular grooves 8 at both ends is integrally formed with the wheel hub mounting base 3, which reduces the weight of the wheel hub while improving the structural strength.

[0032] 3): The combination of magnesium alloy rim 1, carbon fiber reinforced composite Y-shaped spoke 2 and high-strength aluminum alloy hub mounting seat 3, through the reasonable combination of different lightweight and high-strength materials, reduces the overall weight while avoiding a decrease in strength.

[0033] In summary, this motorcycle features a lightweight, high-strength one-piece wheel rim. The rim 1 is made of magnesium alloy, which significantly reduces weight while maintaining the strength of the annular closed structure. The Y-shaped spokes 2 are made of carbon fiber reinforced composite material. The weight-reducing grooves 5 in the vertical part and the strip grooves 6 in the inclined support part reduce material usage to achieve weight reduction. The first stiffening plate 7 in the strip groove 6 is integrally formed with the Y-shaped spokes 2 to enhance the overall strength of the spokes. The hub mounting base 3 is made of high-strength aluminum alloy. The second stiffening plates 9 in the annular grooves 8 at both ends are integrally formed with the hub mounting base 3, which reduces the weight of the hub while improving structural strength. The combination of magnesium alloy rim 1, carbon fiber reinforced composite Y-shaped spokes 2, and high-strength aluminum alloy hub mount 3 achieves overall weight reduction while avoiding strength degradation through the rational combination of different lightweight and high-strength materials. The weight-reducing grooves 5 and strip grooves 6 reduce material usage, while the first stiffening plate 7 and the second stiffening plate 9 respectively reinforce the spokes and hub mount, effectively solving the problem of balancing lightweight and high strength in existing wheel rims. This reduces the unsprung mass of the vehicle, improves acceleration, braking performance, and handling agility. The Y-shaped spokes 2 are arranged in a circumferential array, with the outer end integrally formed with the spoke connection part 4 of the rim 1 and the inner end integrally formed with the outer wall of the hub mount 3, forming a uniform force transmission path. The annular reinforcing structure 12 on the outer wall of the rim 1 is integrally formed with it, enhancing the rim's resistance to deformation. The second stiffening plate 9 of the hub mount 3 is arranged in a circumferential array, strengthening the structural strength of the hub-spoke connection part. The Y-shaped spoke 2's structural design and its integral molding connection with the rim 1 and hub mount 3 ensure even distribution of vehicle weight and driving force, reducing stress concentration. The annular reinforcing structure 12 enhances the rim 1's resistance to deformation under tire pressure and road impact. The second stiffening plate 9 strengthens the connection between the hub mount 3 and the spokes, preventing fatigue damage in this complex stress area. This solves the problems of poor stability and easy damage caused by the unreasonable design of existing wheel rims, extends the service life of the wheel rim, and improves the smoothness and safety of motorcycle riding.
