Technical Field

[0001] The present invention belongs to the technical field of automotive parts. Specifically, the present invention relates to a wheel and a vehicle. Background Art

[0002] Currently, the wheels of passenger cars are mainly assembled by tires and wheels, and a certain amount of low-pressure air is filled to achieve the load-bearing function. The wheels of this structure deform greatly during the driving of the vehicle, generating a large amount of heat, having a high rolling resistance, reduced flexural resistance performance, and being prone to air leakage or tire burst risks when a sharp object pierces the tread; at the same time, the wheels of this structure mainly rely on the internal air pressure for support. Since the air pressure filled in the tire is limited, the overall stiffness of the wheel is low, resulting in inaccurate and unstable handling performance of the vehicle.

[0003] Moreover, when replacing the tire of the wheel, the entire tire needs to be replaced, causing a large waste. Summary of the Invention

[0007] The annular tread is installed on the support block, the support block is installed on the wheel hub, and a limiting band is provided on the support block. The limiting band applies a certain tightening force to the support block to limit the circumferential expansion of the support block.

[0008] A slider is provided on the support block, and a slideway for accommodating the slider is provided inside the wheel hub. The slider can move relative to the wheel hub in the slideway.

[0009] A plurality of the sliders are provided, and all the sliders are arranged in sequence along the axial direction of the support block.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] As Figure 1 shown, the present invention provides a wheel including a wheel hub, an annular tread surface 2, and a support block 3 provided between the wheel hub and the annular tread surface 2. An air storage chamber 1 for storing compressed air or inert gas is provided inside the wheel hub.

[0021] Specifically, as Figure 1As shown in the figure, the air storage chamber 1 is a cavity provided inside the wheel hub. The air storage chamber 1 extends along the entire circumference inside the wheel hub. The wheel hub is made of metal material. Compressed air or inert gas is stored in the air storage chamber 1 of the wheel hub, so that the wheel is no longer affected by spiky objects and deformation during driving, eliminating the possibility of tire blowout and air leakage.

[0022] As Figure 1 shown in the figure, the annular tread 2 is installed on the support block 3, and the support block 3 is installed on the wheel hub. The annular tread 2 is a circular ring structure, and the support block 3 is an arc-shaped structure. A plurality of support blocks 3 are provided, and all the support blocks 3 are evenly distributed along the circumference on the outside of the wheel hub. All the support blocks 3 jointly surround the wheel hub, and the annular tread 2 surrounds all the support blocks 3. The annular tread 2 is made of rubber material. Designing the tire into a tread reduces the amount of rubber used, greatly saving the replacement cost and the waste and secondary treatment of the used tire body of traditional tires. At the same time, only the grounding part is made of rubber material, greatly improving the rigidity of the entire wheel and the handling and stability performance of the whole vehicle.

[0023] As Figure 1 shown in the figure, the annular tread 2 is the only structural member in contact with the ground on the wheel. The outer circular surface of the annular tread 2 is designed as an arc surface with a large curvature. The outer circular surface of the annular tread 2 contacts the ground. The inner circular surface of the annular tread 2 is a cylindrical surface, and the inner circular surface of the annular tread 2 contacts the outer circular surface of the support block 3. The outer circular surface of the support block 3 is an arc surface. Both ends of the annular tread 2 in the axial direction are designed as concave arc surface structures. Certain pattern patterns are engraved on the upper surface of the outer circular surface of the annular tread 2 to generate frictional force when contacting the dry or wet ground, and to transmit and realize the rolling and steering functions of the wheel.

[0024] Preferably, the belt material of the annular tread 2 is a uniform and dense substance, which evenly bears the weight of the whole vehicle to ensure uniform stress distribution. The tread belt is designed to be removable from the support block 3. When the tread belt wears to the limit, the tread belt can be replaced for the second time. The shape and quality of the discarded tread belt after replacement are lower than those of traditional discarded tires, and at the same time, the internal structure is uniform, which is convenient for recycling and secondary treatment.

[0025] As Figure 1 shown in the figure, the support block 3 is an important load-bearing structural member on the wheel. Rim flanges 9 are provided at both ends of the support block 3 in the axial direction. The rim flanges 9 extend radially outward from the support block 3. The rim flanges 9 and the support block 3 are coaxially arranged. The annular tread 2 is located between the two rim flanges 9. The outer circular surfaces of the two rim flanges 9 are respectively in contact with the two concave arc surfaces provided at both ends of the annular tread 2. A certain locking structure is designed inside the support block 3 to ensure close cooperation with the tread belt without detachment or sliding, and at the same time to transmit the forces such as traction, braking, and steering of the whole vehicle to the annular tread 2.

[0026] As Figure 1As shown, a limiting band 4 is provided on the support block 3. The limiting band 4 applies a certain tightening force to all the support blocks 3. The limiting band 4 surrounds all the support blocks 3 to restrict the circumferential expansion of the support blocks 3. A plurality of limiting bands 4 are provided, and all the limiting bands 4 are arranged in sequence along the length direction of the support block 3. The length direction of the support block 3 is parallel to the axial direction of the annular tread 2. The limiting band 4 is a structure with a semi-circular cross-section. A receiving groove for the limiting band 4 is provided on the outer circular surface of the support block 3. The shape of the receiving groove matches the shape of the limiting band 4. The outer circular surface of the support block 3 is in contact with the inner circular surface of the annular tread 2. The limiting band 4 is a circular ring structure, and the limiting band 4 is located between the two flanges 9.

[0027] The limiting band 4 is a component in the wheel that plays a tightening role. The limiting band 4 is composed of a material with high modulus and high elasticity. The limiting band 4 ensures a tight connection with the support block 3 and can apply a certain tightening force to the support block 3 in the radial direction. The limiting band 4 plays a certain limiting role in the circumferential expansion of the support block 3, ensuring that the support block 3 can move relative to the hub in the radial direction within a set stroke.

[0028] As Figure 1 shown, a slider 5 is provided on the support block 3, and a slideway 6 for receiving the slider 5 is provided in the hub. The slider 5 can move relative to the hub within the slideway 6. A plurality of sliders 5 are provided, and all the sliders 5 are arranged in sequence along the length direction of the support block 3. The slider 5 is fixedly connected to the inner circular surface of the support block 3. The slider 5 extends radially inward along the support block 3. The shape of the slider 5 matches the shape of the slideway 6. The slider 5 is a T-shaped structure, and the slideway 6 is a T-shaped groove provided in the hub. The slider 5 has a certain length and can freely move back and forth within the slideway 6.

[0029] As Figure 1 shown, in this embodiment, three sliders 5 are provided on the support block 3.

[0030] As Figure 1 shown, an air vent hole 7 communicating with the slideway 6 and the air storage chamber 1 is provided in the hub. The air vent hole 7 is located between the slideway 6 and the air storage chamber 1. A plurality of air vent holes 7 are provided, and each slideway 6 communicates with the air storage chamber 1 through an air vent hole 7. The slideway 6 forms an opening on the outer circular surface of the hub for the slider 5 to pass through. The end with a smaller width of the slider 5 is fixedly connected to the support block 3, and the end with a larger width of the slider 5 is located within the slideway 6.

[0031] As Figure 1As shown, the wheel hub is an important basic structural component in the wheel. The air storage chamber 1 is a closed annular air inner cavity chamber. The wheel hub has certain compressive, anti-explosion and load-bearing capacities and can bear air or other inert gases at a certain pressure. A slideway 6 with a certain shape is designed in the middle of the wheel hub. The slideway 6 and the air storage chamber 1 are connected through a ventilation hole 7. The compressed air or inert gas in the air storage chamber 1 can enter the slideway 6 through the ventilation hole 7, and then can push the slider 5 in the slideway 6 to move radially away from the axis of the wheel hub in the slideway 6.

[0032] As Figure 1 shown, protrusions 8 are provided at both axial ends of the wheel hub. The protrusions 8 are of an annular structure and extend radially outward of the wheel hub. The wheel hub and the protrusions 8 are coaxially arranged. All the support blocks 3 are located between the two protrusions 8. The two protrusions 8 are arranged opposite to the two wheel rims 9 respectively. The protrusions 8 are used for cooperation and limitation with the support blocks 3 to prevent the air storage chamber 1 from being damaged after the wheel is overloaded.

[0033] After a certain pressure of air or other inert gas is filled into the air storage chamber 1 of the wheel, the gas in the air storage chamber 1 will flow into each slideway 6. After the slider 5 on the support block 3 is affected by the pressure of the gas entering the slideway 6, a force in the tread direction will be generated and the slider will move in the tread direction. At this time, the circumferential stretching deformation of the limiting belt 4 will occur, and the tightening force of the limiting belt 4 will become larger. When the slider 5 moves to a certain position, when the tightening force applied by the limiting belt 4 to the support block 3 and the pressure generated by the high-pressure gas in the slideway 6 finally reach equilibrium, the whole vehicle wheel is stable at a relative fixed position, and the slider 5 is also relatively fixed at the equilibrium position in the slideway 6. This equilibrium position is called the inflation equilibrium value.

[0034] When the wheel is installed on the axle and slowly lands, the annular tread 2 at the grounding position is deformed under the influence of the whole vehicle load. The contact area between the annular tread 2 and the ground gradually increases, and more support blocks 3 will move towards the wheel axis direction. The tightening force applied by the limiting belt 4 to the support block 3 becomes smaller. When the grounding area of the annular tread 2 increases to a certain extent, the supporting force generated by the cooperative action of a certain number of support blocks 3 cancels out the tightening force generated by the limiting belt 4 and the whole vehicle load and then reaches equilibrium. The slider 5 moves to another relatively fixed position in the slideway 6. This position is called the static load equilibrium value. When the wheel is running on the road surface, the internal structure of the wheel changes cyclically between the inflation equilibrium value and the static load equilibrium value.

[0035] Compared with traditional wheels that experience tread deformation, sidewall deformation, and bead deformation during driving, only the tread of the new - structure wheel of the present invention undergoes slight deformation during driving, reducing the types of rolling - resistance sources. At the same time, the new - structure wheel can withstand a much higher air pressure than traditional tires, has better stiffness performance, and can effectively reduce rolling resistance. The tread of traditional wheels is directly connected to compressed air, and when punctured by a sharp object, it directly causes air leakage or tire blowout. The new - structure wheel of the present invention uses support blocks 3 to support the annular tread 2, eliminating the possibility of tire blowout and air leakage. The traditional wheel has a certain time - delay drawback in transmitting traction and braking force through the sidewall. The new - structure wheel of the present invention eliminates the time - delay by transmitting through support blocks 3, improving the accuracy of the vehicle's handling and stability.

[0036] The present invention also provides a vehicle, including a wheel with the above - described structure. The specific structure of this wheel can be referred to Figure 1 , and will not be elaborated here. Since the vehicle of the present invention includes the wheel in the above - mentioned embodiment, it has all the advantages of the above - mentioned wheel.

[0037] The present invention has been described exemplarily above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above - mentioned manner. As long as various non - substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
