It is widely used for patrol, passenger and cargo transportation, etc., and is also used as a sports equipment. Most of its wheel parts are connected to the engine axle, and a rubber tire is assembled to support the vehicle body and ensure smooth driving.

[0003] The wheel part of a motorcycle directly affects the stability, strength and even fuel efficiency of the vehicle during operation. However, in order to ensure the strength of the vehicle, the wheel part usually uses high-strength materials in combination with the tire. However, the support between the hub and the rim will increase the weight of the vehicle body, and the inertial force that needs to be overcome during driving will also increase accordingly. More seriously, it will even increase the engine load and reduce the fuel efficiency.

[0004] Therefore, a high-strength and lightweight rim is proposed. Content of the Utility Model

Specific embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-6 , the present utility model provides a technical solution:

[0026] A high-strength and lightweight rim, including a fixed hub 1, a connecting rim 2 and a plurality of spokes 3. The outer side of the fixed hub 1 is clamped with the spokes 3, and the outer side of the spokes 3 is movably connected with the connecting rim 2;

[0027] The connecting rim 2 includes a tire clamping part 201, a connecting part 202 and a base part 203. The connecting part 202 is arranged in the middle of the inner side of the base part 203 and is provided with a stepped hole for cooperating with the spokes 3. The tire clamping part 201 is arranged on the base part 203 and the cross section is in a funnel shape. The tire clamping part 201, the connecting part 202 and the base part 203 are integrally formed;

[0028] The fixed hub 1 includes a sleeve shaft part 101 and a strength shell 102. The front side and the rear side of the strength shell 102 are both concave, and the inner side of the strength shell 102 is movably connected with the sleeve shaft part 101

[0029] In this embodiment: By providing a fixed hub 1 for connecting the structure to the axle, its sleeve shaft portion 101 can be sleeved outside the axle for easy structural connection. The hollowed-out part between the strength outer shell 102 and the sleeve shaft portion 101 can reduce the weight of the structure, while ensuring that the structure has sufficient strength to protect the axle and providing an installation position for structures such as the spoke 3. The connecting rim 2 cooperates with the fixed hub 1 and the spoke 3 to form a wheel support portion. The tire clamping portion 201 of the connecting rim 2 is used for clamping and fixing with the tire, the base portion 203 provides the strength support for the connecting rim 2, and the connecting portion 202 is used for fixing the spoke 3. The setting of the porous structure can further reduce the self-weight of the structure and improve the heat dissipation performance during continuous operation. The shape of the spoke 3 is changed to keep the easily breakable part with sufficient strength during normal use while reducing the weight. Since the self-weight of the structure is reduced, the inertial force that the vehicle needs to resist will also be reduced, reducing the load on the engine and achieving the effect of saving fuel to a certain extent. At the same time, rapid heat dissipation can prevent the structure from being easily deformed due to high temperature.

[0030] Specifically, as Figure 5 shown, a number of assembly holes 4 and a number of heat dissipation holes 5 are provided on the inner side of the strength outer shell 102, and the inner side of the assembly hole 4 is movably connected to the spoke 3.

[0031] Specifically, as Figure 3 and Figure 5 shown, a limit protrusion 6 is provided on the side of the spoke 3 close to the fixed hub 1, and the limit protrusion 6 is provided on the inner side of the assembly hole 4.

[0032] Specifically, as Figure 3 shown, a connecting bolt 7 is provided on the side of the spoke 3 away from the limit protrusion 6, the connecting bolt 7 is provided on the inner side of the connecting portion 202, the radius of both ends of the spoke 3 is widened, and the radius of the middle part of the spoke 3 is reduced.

[0033] In this embodiment: By providing the assembly hole 4 and cooperating with the protruding part of the spoke 3 to clamp the spoke 3 inside the fixed hub 1, and at the same time cooperating with the connecting bolt 7, after the spoke 3 extends out from the inner side of the connecting portion 202, it can be installed and fixed, and the tension degree of the spoke 3 can be adjusted as needed. The heat dissipation hole 5 provided on the inner side of the strength outer shell 102 can assist the structure in heat dissipation and further improve the cooling effect. The spoke 3 adopts a thicker diameter in the area with greater force to ensure sufficient strength to bear the load, and a thinner diameter in the area with smaller force to reduce the weight without affecting the overall strength, which can make the strength distribution of the spoke 3 more reasonable and can better absorb and disperse the impact energy. When the rim is subjected to an external impact, the thicker part can provide greater rigidity and slow down the transmission of the impact; while the thinner part has a certain elastic deformation ability and can absorb part of the impact energy, thereby reducing the damage to the entire rim structure.

[0034] Specifically, as Figure 5 shown, a bearing 8 is clamped inside the fixed hub 1, and the inner side of the bearing 8 is clamped with an external wheel axle.

[0035] Specifically, as Figure 3 and Figure 5 shown, both ends of the spoke 3 are provided with widened portions, and the widened portions are used in cooperation with the limiting protrusions 6 and the connecting bolts 7.

[0036] Specifically, as Figure 5 shown, the adjacent two spokes 3 are respectively clamped with the front assembly hole 4 and the rear assembly hole 4 on the side close to the fixed hub 1.

[0037] In this embodiment: By providing the bearing 8 for connecting the wheel axle and enabling the wheel axle to rotate reasonably and smoothly, the provided widened portion is used to ensure that the connection part of the structure has sufficient strength. Because most of the connection positions of the spoke 3 will contact the connected structure, friction will also occur when radial displacement or deformation occurs, so it is more likely to break. Widening only at this position can effectively ensure the strength of the structure. At the same time, because the un-widened part of the structure has a relatively light total weight, it can also play the role of reasonably distributing the structure weight.

[0038] Working principle: When the structure is in use, it can be connected to the wheel axle through the sleeve shaft part 101 of the fixed hub 1, and the strength outer shell 102, the spoke 3, and the connecting rim 2 provide support between the tire and the vehicle. The space between the strength outer shell 102 and the sleeve shaft part 101 is set as a hollow to reduce the weight of the structure, and at the same time ensure that the structure has sufficient strength to protect the wheel axle. The tire clamping part 201 of the connecting rim 2 clamps and fixes the tire. The provided heat dissipation holes 5 can further reduce the self-weight of the structure, improve the heat dissipation performance during continuous operation, and at the same time reduce the weight. The widened portion is used to ensure that the connection part of the structure has sufficient strength. At the same time, the radius is reduced at the position where the outer side of the spoke 3 is uniformly stressed and not easily damaged. Because the self-weight of the structure is reduced, the inertial force that the vehicle needs to resist will also be reduced.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
