Description

Technical Field

[0001] The utility model is used in the field of automobiles, and particularly relates to a wheel hub, a wheel and a vehicle. Background Art

[0002] The wheel is one of the important components of an automobile. It directly contacts the road surface and, together with the vehicle suspension, alleviates the impact received during the vehicle's travel, ensuring good riding comfort and driving smoothness of the vehicle; ensuring good adhesion between the wheel and the road surface, improving the tractability, braking performance and passability of the vehicle; and bearing the weight of the vehicle. The important role played by the wheel in the vehicle has been increasingly emphasized by people.

[0003] The currently used automobile wheels adopt a symmetric structure design, that is, the two side flanges of the wheel hub are of equal diameter, and the corresponding tires also have sidewalls of equal thickness on both sides. Among them, the diameter of the tire is generally much larger than the diameter of the wheel hub flange. The greater the difference between the tire diameter and the wheel hub diameter, the worse the safety after a flat tire. Moreover, due to the symmetric structure design, it is not easy to distinguish the inner reverse sides of the wheel hub and the tire, and the installation convenience is poor. Moreover, for symmetric wheels, it is difficult to reconcile the contradictions among the comfort, handling performance and durability of the wheels. Summary of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a wheel hub, a wheel and a vehicle.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] In a first aspect, a wheel hub includes a rim and spokes. One axial side edge of the rim is provided with a first flange, and the other axial side edge of the rim is provided with a second flange. The wheel hub forms a first flange groove for assembling a tire inside the first flange, and the wheel hub forms a second flange groove for assembling a tire inside the second flange. One end of the rim where the second flange is located expands radially outward compared with the end where the first flange is located. The diameter of the first flange is smaller than the diameter of the second flange, and the diameter of the first flange groove is smaller than the diameter of the second flange groove.

[0007] In combination with the first aspect, in some implementation manners of the first aspect, the spokes are connected to the end of the rim where the second flange is located.

[0008] In combination with the first aspect and the above implementation manners, in some implementation manners of the first aspect, a sunken tire cavity groove is provided on the outer wall surface of the rim between the first flange groove and the second flange groove, and the tire cavity groove extends along the circumferential direction of the rim.

[0009] Combined with the first aspect and the above implementation manners, in some implementation manners of the first aspect, a plurality of ribs are provided in the tire cavity, and the plurality of ribs are spaced apart along the circumferential direction of the rim.

[0010] Combined with the first aspect and the above implementation manners, in some implementation manners of the first aspect, the plurality of ribs are inclined in the same direction with respect to the axis of the hub, and the plurality of ribs form vortex vanes on the outer wall surface of the rim.

[0011] Combined with the first aspect and the above implementation manners, in some implementation manners of the first aspect, the cross-section of the rib is triangular.

[0012] In a second aspect, a wheel includes a tire and a hub according to any one of the implementation manners in the first aspect. The tire includes a first tire sidewall, a second tire sidewall, and a tread between the first tire sidewall and the second tire sidewall. An inner edge of the first tire sidewall forms a first bead, and an inner edge of the second tire sidewall forms a second bead. The diameter of the first bead is smaller than the diameter of the second bead. The first bead is embedded in the first rim groove and cooperates with the first rim. The second bead is embedded in the second rim groove and cooperates with the second rim.

[0013] Combined with the second aspect, in some implementation manners of the second aspect, reinforcing ribs are provided in the tire cavity of the tire, and the reinforcing ribs protrude from the tire sidewall into the tire cavity.

[0014] Combined with the second aspect and the above implementation manners, in some implementation manners of the second aspect, the reinforcing ribs extend obliquely from the inner wall surface of the first tire sidewall to the inner wall surface of the tread, and the plurality of reinforcing ribs are evenly distributed along the circumferential direction of the tire.

[0015] In a third aspect, a vehicle includes a wheel according to any one of the implementation manners in the second aspect.

[0016] One of the technical solutions in the above technical solutions has at least the following advantages or beneficial effects: In the embodiments of the present invention, one end of the rim of the wheel hub expands outward, forming an asymmetric wheel hub with a large rim at one end and a small rim at the other end. When in use, it can be matched with a tire that also adopts an asymmetric design. The asymmetric tire and the asymmetric wheel hub form a stable structure with a triangular cross-section, so that one end of the wheel has a larger aspect ratio and the other end has a smaller aspect ratio, combining the characteristics of wheels with different aspect ratios. It can not only improve the handling performance but also ensure comfort and durability. At the same time, when the wheel is installed on the vehicle body, the rim of the wheel hub is in a horn inverted cone shape. During movement, the force on the vehicle is transformed from the original up and down vibration into an axial longitudinal force, and the reaction forces of the left and right symmetric wheels cancel each other out, greatly reducing the vehicle body vibration. In addition, the asymmetric structural design also makes it easier to distinguish the inner reverse sides of the tire and the wheel hub. During installation, it only needs to be inserted unidirectionally, making the installation more convenient. Moreover, when a tire suddenly bursts during the driving of the vehicle, the supporting effect of the tire is lost. At this time, the second rim with a larger diameter supports and bears the vehicle. Since the diameter of the second rim of the wheel hub is larger, the vehicle will not tilt significantly, ensuring that the vehicle will not roll over until it stops during the braking process, thus playing a safety protection role.

[0030] See Figure 1 、 Figure 2 、 Figure 7, an embodiment of the present utility model provides a wheel hub 100, which includes a rim 101 and spokes 102. The rim 101 and the spokes 102 can be integrally formed or assembled into a whole. The rim 101 serves as an assembly and supporting structure for the tire 200, extending from one side edge to the other side edge along the axial direction. One side edge of the rim 101 along the axial direction is provided with a first flange 103, and the other side edge of the rim 101 along the axial direction is provided with a second flange 104. The first flange 103 extends radially outward, and the wheel hub 100 forms a first flange groove 105 for assembling the tire 200 inside the first flange 103. The first flange groove 105 is located at the transition position between the outer wall surface of the rim 101 and the first flange 103. The second flange 104 extends radially outward, and the wheel hub 100 forms a second flange groove 106 for assembling the tire 200 inside the second flange 104. The second flange groove 106 is located at the transition position between the outer wall surface of the rim 101 and the second flange 104. After the tire 200 is assembled on the wheel hub 100, positioning and sealed installation are achieved through the first flange 103 and the second flange 104. Among them, the end where the second flange 104 of the rim 101 is located is radially expanded compared to the end where the first flange 103 is located. The diameter of the first flange 103 is smaller than the diameter of the second flange 104, and the diameter of the first flange groove 105 is smaller than the diameter of the second flange groove 106.

[0031] See Figure 1 , Figure 2 , Figure 7 , in an embodiment of the present utility model, one end of the rim 101 of the wheel hub 100 is expanded outward, forming an asymmetric wheel hub 100 with a large flange at one end and a small flange at the other end. When in use, it can be matched with a tire 200 that also adopts an asymmetric design. The asymmetric tire 200 and the asymmetric wheel hub 100 form a stable triangular cross-sectional structure, so that one end of the wheel has a larger aspect ratio and the other end has a smaller aspect ratio, combining the characteristics of wheels with different aspect ratios, which can not only improve the handling performance but also ensure comfort and durability. At the same time, when the wheel is installed on the vehicle body, the rim 101 of the wheel hub 100 is in a trumpet inverted cone shape. During movement, the force on the vehicle is transformed from the original up and down vibration into an axial longitudinal force, and the reaction forces of the left and right symmetric wheels cancel each other out, greatly reducing the vehicle body vibration. In addition, the asymmetric structural design also makes it easier to distinguish the inner reverse sides of the tire 200 and the wheel hub 100. During installation, it only needs to be inserted unidirectionally, making the installation more convenient. Moreover, when the tire 200 suddenly bursts during the vehicle's travel, the supporting effect of the tire 200 is lost. At this time, the second flange 104 with a larger diameter supports and bears the vehicle. Since the diameter of the second flange 104 of the wheel hub 100 is larger, the vehicle will not tilt significantly, ensuring that the vehicle will not roll over until it stops during the braking process, thus playing a safety protection role.

[0032] The spokes 102 are connected to the inside of the rim 101. For example, in some embodiments, seeFigure 7 , the spoke 102 is connected to one end where the second rim 104 of the rim 101 is located. When in use, the side where the second rim 104 is located is installed outward on the vehicle, which improves the handling performance of the tire 200 and the wheel hub 100. At the same time, when viewed from the outside, the wheel has a larger aspect ratio and a more premium look.

[0033] In some embodiments, referring to Figure 2 、 Figure 3 , a sunken cavity groove 107 is provided on the outer wall surface of the rim 101 between the first rim groove 105 and the second rim groove 106, and the cavity groove 107 extends along the circumferential direction of the rim 101. The tire 200 cooperating with the wheel hub 100 is an inflated tire 200, and a cavity is formed between the tire 200 and the rim 101. The cavity is used to inflate gas, and air can be pressed into the cavity. By providing the cavity groove 107, the volume of the cavity can be increased, further improving the comfort of the wheel.

[0034] In some embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 , a plurality of ribs 108 are provided in the cavity groove 107, and the plurality of ribs 108 are spaced apart along the circumferential direction of the rim 101. The ribs 108 are provided to form a sound-absorbing structure inside the wheel hub 100 to reflect and cancel the cavity resonance sound waves, thereby reducing the tire noise.

[0035] Furthermore, referring to Figure 2 、 Figure 3 , the plurality of ribs 108 are inclined in the same direction with respect to the axis of the wheel hub 100, and the plurality of ribs 108 form vortex vanes on the outer wall surface of the rim 101. On the one hand, the plurality of ribs 108 inclined with respect to the axis of the wheel hub 100 can further cancel the longitudinal sound waves and further reduce the tire noise. On the other hand, the vortex vanes can drive the circulation of the air inside the tire, can disturb the air inside the tire during driving, and promote the formation of air flow, avoiding local overheating of the tire 200.

[0036] It can be understood that the ribs 108 can be set to various cross-sectional shapes. For example, in some embodiments, referring to Figure 4 、 Figure 5 , the cross-section of the rib 108 is triangular. The triangular rib 108 has stronger stability, is more helpful for demolding and manufacturing, and reduces the forming difficulty.

[0037] An embodiment of the present invention provides a wheel, referring to Figure 6 、 Figure 7, the wheel includes a tire 200 and a wheel hub 100 as in any of the above embodiments. The tire 200 includes a first sidewall 201, a second sidewall 202, and a tread 203 between the first sidewall 201 and the second sidewall 202. The tread 203 of the tire 200 is used to directly contact the road surface. The first sidewall 201 and the second sidewall 202 do not contact the ground. The sidewalls mainly work in a flexed state and must withstand large mechanical deformations. The thickness of the sidewalls can be slightly thinner than that of the tread 203. The inner edge of the first sidewall 201 forms a first bead 204, and the inner edge of the second sidewall 202 forms a second bead 205. The diameter of the first bead 204 is smaller than that of the second bead 205. The first bead 204 is inserted into the first rim groove 105 and cooperates with the first rim 103, and the second bead 205 is inserted into the second rim groove 106 and cooperates with the second rim 104 to assemble the tire 200 onto the wheel hub 100, enabling the tire 200 to be firmly fixed on the wheel hub 100 and resisting the force that causes the outer tire to separate from the wheel hub 100 during vehicle operation.

[0038] Combined Figure 6 , Figure 7 , in an embodiment of the present invention, one end of the rim 101 of the wheel hub 100 expands outward to form an asymmetric wheel hub 100 with a larger rim at one end and a smaller rim at the other end. When in use, it can be matched with a tire 200 that also adopts an asymmetric design. The asymmetric tire 200 and the asymmetric wheel hub 100 form a stable triangular cross-sectional structure, such that one end of the wheel has a larger aspect ratio and the other end has a smaller aspect ratio, combining the characteristics of wheels with different aspect ratios, which can not only improve the handling performance but also ensure comfort and durability. At the same time, when the wheel is installed on the vehicle body, the rim 101 of the wheel hub 100 is in a trumpet-shaped inverted cone. During movement, the force on the vehicle is transformed from the original up-and-down vibration into an axial longitudinal force, and the reaction forces of the left and right symmetric wheels cancel each other out, greatly reducing the vehicle body vibration. In addition, the asymmetric structural design also makes it easier to distinguish the inner reverse sides of the tire 200 and the wheel hub 100. During installation, it only needs to be inserted unidirectionally, making the installation more convenient. Moreover, when the tire 200 suddenly bursts during vehicle travel, the supporting effect of the tire 200 is lost. At this time, the second rim 104 with a larger diameter supports and bears the vehicle. Since the diameter of the second rim 104 of the wheel hub 100 is larger, the vehicle will not tilt significantly, ensuring that the vehicle will not roll over until it stops during braking, thus playing a safety protection role.

[0039] In some examples, referring to Figure 7 , reinforcing ribs 206 are provided in the tire cavity of the tire 200. The reinforcing ribs 206 protrude from one or both sidewalls of the tire 200 into the tire cavity. The reinforcing ribs 206 are used to enhance the vertical support force of the sidewalls, enabling low-speed driving even under insufficient air pressure conditions and having resistance to side wear and bursting.

[0040] Further, referring to Figure 7 , the reinforcing rib 206 extends obliquely from the inner wall surface of the first sidewall 201 to the inner wall surface of the tread 203, and a plurality of reinforcing ribs 206 are evenly distributed along the circumferential direction of the tire 200. In other words, the reinforcing rib 206 is located on the thicker side of the rear of the tire, which is used to improve the vertical supporting force of the sidewall on that side, ensure that the vehicle can still travel at a low speed under the condition of insufficient air pressure, and has resistance to side wear and blowout.

[0041] In some embodiments, referring to Figure 7 , the outer diameter of the first rim 103 is greater than the caliber of the first bead 204, the outer diameter of the first rim 103 is less than the caliber of the second bead 205, and the outer diameter of the second rim 104 is greater than the caliber of the second bead 205. By setting the outer diameter of the first rim 103 to be less than the caliber of the second bead 205, during the process of installing the tire onto the wheel hub, the second bead 205 side of the tire can be oriented towards the first rim 103 side of the wheel hub, and then the first rim 103 of the wheel hub is passed through the second bead 205 of the tire. Finally, the first rim 103 is matched with the first bead 204, and the second rim 104 is matched with the second bead 205, which is convenient for one-way insertion.
