A two-unit centrosymmetrical structure spoke and tire for non-pneumatic tire

Abstract

This invention relates to a two-unit centrosymmetric spoke structure and tire for non-pneumatic tires. The spokes include a glass fiber reinforced structure and a first support structure, a first spoke unit, a second spoke unit, and a second support structure connected sequentially through the glass fiber reinforced structure.

By setting the two support structures and two spoke units to be centrosymmetrically distributed, the spokes achieve a load-bearing effect through a two-unit centrosymmetric arrangement. Under vertical compression, the sum of the internal forces and the torque at the bonding surface is zero, avoiding uneven stress distribution at the adhesive surface, significantly reducing unidirectional tearing force, enhancing the fatigue strength of the adhesive surface, and simultaneously improving the bending and torsional resistance and stability of the spokes.

Description

Technical Field

[0001] This invention relates to the field of tire support structure technology, and more specifically, to a two-unit centrally symmetrical spoke structure and tire for non-pneumatic tires. Background Technology

[0002] As people's living standards improve, all industries are making rapid progress. Safety and low energy consumption are crucial for the survival of every industry. In the automotive industry, vehicle safety is of paramount importance, as it directly impacts a vehicle's sales prospects and overall performance.

[0003] The automotive industry is currently booming, with safety, new energy, energy conservation, and environmental protection becoming key trends in automotive development. Consequently, automakers are increasingly emphasizing research into lightweighting and safety. During vehicle operation, wheels must simultaneously withstand the vehicle's own weight and the stresses generated by various dynamic loads. Therefore, wheel safety has become a crucial indicator for evaluating overall vehicle performance. As automotive components evolve towards high performance, safety, energy efficiency, and reduced emissions, high-strength wheels have become a focal point of research into lightweighting and safety.

[0004] Currently, both domestic and international wheel designs and manufacturing are trending towards lightweight designs. The long and short shoulders of the wheel flange are most susceptible to impact deformation. In actual use, wheel damage is often due to flange deformation. However, whether the wheel flange is impact-resistant depends on the strength of the vehicle's spokes supporting the non-pneumatic tire.

[0005] In the design of spoke structures for non-pneumatic tires both domestically and internationally, a single-piece rigid structure or a double-piece rigid structure with an included angle is typically used as the load-bearing structure, with the outer rubber bonded to the tire. Generally speaking, single-piece structures are often only suitable for low-speed applications due to their poor resistance to bending and torsion during deformation. Double-piece rigid structures with an included angle, with integrated vulcanized rubber, have higher load-bearing capacity and resistance to bending and torsion. However, due to the asymmetry of the rigid structure's tilt angle during deformation, a huge torque is often generated at the bonding surface, resulting in uneven stress distribution on the bonding surface. This leads to a phenomenon where one side is stretched while the other is compressed, ultimately resulting in poor fatigue strength of the spoke-tread bond and tearing damage, causing spoke failure. Summary of the Invention

[0006] This invention aims to overcome the problems of existing non-pneumatic tire spokes for vehicles, which use a single-piece rigid structure or a double-piece rigid structure with an included angle, with rubber attached to the tire for load-bearing. Such asymmetrical spoke structures have problems such as insufficient load-bearing capacity, poor structural bending and torsional resistance, poor fatigue strength of the adhesive surface caused by the accumulation of internal bending moments when the structure is under load, and tearing failure of the adhesive surface. This invention provides a two-unit centrally symmetrical spoke structure and tire for non-pneumatic tires.

[0010] Furthermore, as a preferred technical solution, the first supporting fiberglass component and the first end of the transition fiberglass component are connected at a first angle along a first direction, and the second supporting fiberglass component and the second end of the transition fiberglass component are connected at a second angle along a second direction.

[0013] Furthermore, as a preferred technical solution, the first radiating unit includes a first nose connector and a first nose fabric layer. The first nose connector is disposed on the inner side of the opposite ends of the first supporting fiberglass member and the transition fiberglass member, and the first nose fabric layer is disposed on the outer side of the opposite ends of the first supporting fiberglass member and the transition fiberglass member. The second radiating unit includes a second nose connector and a second nose fabric layer. The second nose connector is disposed on the inner side of the opposite ends of the second supporting fiberglass member and the transition fiberglass member, and the second nose fabric layer is disposed on the outer side of the opposite ends of the second supporting fiberglass member and the transition fiberglass member.

[0014] Furthermore, as a preferred technical solution, the first included angle and the second included angle are the same, and the angles of the first included angle and the second included angle are set within the range of 100°-120°.

[0015] Furthermore, as a preferred technical solution, the opposite ends of the first supporting fiberglass member and the transition fiberglass member are bent toward the outer side of the first supporting fiberglass member to form a third included angle, and the opposite ends of the second supporting fiberglass member and the transition fiberglass member are bent toward the outer side of the second supporting fiberglass member to form a fourth included angle.

[0016] Furthermore, as a preferred technical solution, the thickness of the rubber layer on the surface of the glass fiber reinforced structure is greater than or equal to 0.1 mm.

[0017] Furthermore, as a preferred technical solution, the glass fiber reinforced structure is prepared by composite material of continuous glass fiber and epoxy vinyl ester resin.

This results in a two-unit centrally symmetrical structure for the spokes, achieving a load-bearing effect through a centrally symmetrical arrangement. With this two-unit centrally symmetrical structure, the sum of the internal forces and torques on the bonding surface is zero during vertical compression.

It greatly alleviates the problem of poor adhesion fatigue strength between the spokes and the tread of non-pneumatic tires, which can easily lead to tearing and spoke failure. Simultaneously, it enhances the bending and torsional resistance of the spoke structure and improves its stability. Attached Figure Description

[0031] Example 1

[0032] This embodiment addresses the problems of existing designs for non-pneumatic tire spokes on vehicles, which use a single-piece rigid structure or a double-piece rigid structure with an included angle, bonded to the tire with rubber for load-bearing. These asymmetrical spoke structures suffer from insufficient load-bearing capacity, poor bending and torsional resistance, poor fatigue strength of the adhesive surface due to accumulated internal bending moments under load, and tearing failure of the adhesive surface. The embodiment discloses a two-unit centrally symmetrical spoke structure for non-pneumatic tires. This two-unit centrally symmetrical spoke structure results in zero sum of internal forces and torque at the adhesive surface during vertical compression, thus avoiding uneven stress distribution at the adhesive surface, significantly reducing unidirectional tearing force, and enhancing the fatigue strength of the adhesive surface. This greatly alleviates the problems of poor adhesion fatigue strength between the spokes and the tread of the non-pneumatic tire, and the susceptibility to tearing failure leading to spoke failure. Simultaneously, it enhances the bending and torsional resistance of the spoke structure and improves its stability.

[0033] This embodiment discloses a two-unit centrally symmetrical spoke structure for non-pneumatic tires, such as... Figure 1 As shown, it includes a glass fiber reinforced structure 1 and a first wing structure 2, a first wing unit 3, a second wing unit 4 and a second wing structure 5 connected in sequence through the glass fiber reinforced structure 1; the first wing structure 2 and the second wing structure 5 are symmetrically distributed with respect to the first center point, and the first wing unit 3 and the second wing unit 4 are symmetrically distributed with respect to the second center point.

[0034] In this embodiment, the spokes are arranged in a centrally symmetrical manner by setting the first support structure 2 and the second support structure 5 as centrally symmetrical, and setting the first spoke unit 3 and the second spoke unit 4 as centrally symmetrical, so that the spokes have a two-unit centrally symmetrical structure, and achieve the load-bearing effect by coupling in a centrally symmetrical arrangement.

[0035] In a preferred embodiment, the first center point and the second center point coincide, that is, the first branch structure 2 and the second branch structure 5, as well as the first argument unit 3 and the second argument unit 4 are centrally symmetrically distributed with respect to the same center point.

[0036] Furthermore, given that the first branch structure 2 and the second branch structure 5 are arranged in a centrally symmetrical distribution, and the first radix unit 3 and the second radix unit 4 are arranged in a centrally symmetrical distribution, and the first branch structure 2, the first radix unit 3, the second radix unit 4 and the second branch structure 5 are connected in sequence through the glass fiber reinforced structure 1, the glass fiber reinforced structure 1 is also a centrally symmetrical structure.

[0037] In this embodiment, as Figure 2 As shown: The fiberglass reinforced structure 1 includes a first supporting fiberglass member 11, a transition fiberglass member 12 and a second supporting fiberglass member 13 connected in sequence. The first pivot structure 2 and the second pivot structure 5 are respectively disposed at opposite ends of the first supporting fiberglass member 11 and the second supporting fiberglass member 13. The first radiating unit 3 is disposed at the connection between the first supporting fiberglass member 11 and the transition fiberglass member 12. The second radiating unit 4 is disposed at the connection between the second supporting fiberglass member 13 and the transition fiberglass member 12.

[0038] Alternatively, it can be understood that the first support structure 2 and the second support structure 5 are respectively located at the opposite ends of the first supporting fiberglass component 11 and the second supporting fiberglass component 13, and the first supporting fiberglass component 11 and the transition fiberglass component 12 are connected by the first spoke unit 3, and the second supporting fiberglass component 13 and the transition fiberglass component 12 are connected by the second spoke unit 4; or, the first support structure 2 and the first spoke unit 3 are connected by the first supporting fiberglass component 11, the first spoke unit 3 and the second spoke unit 4 are connected by the transition fiberglass component 12, and the second spoke unit 4 and the second support structure 5 are connected by the second supporting fiberglass component 13.

[0039] In a preferred embodiment, the specific shape of the glass fiber reinforced structure 1 is as follows: Figure 3 As shown: the first supporting fiberglass component 11 and the first end of the transition fiberglass component 12 are connected at a first angle 14 along the first direction, and the second supporting fiberglass component 13 and the second end of the transition fiberglass component 12 are connected at a second angle 15 along the second direction.

[0040] The first supporting fiberglass member 11 and the transition fiberglass member 12, after being connected, form a continuous V-shaped structure, and the second supporting fiberglass member 13 and the transition fiberglass member 12 also form a continuous V-shaped structure. That is to say, the first supporting fiberglass member 11, the transition fiberglass member 12, and the second supporting fiberglass member 13 are sequentially connected into a whole, and the connected fiberglass reinforced structure 1 is Z-shaped.

[0041] Furthermore, in order to achieve a centrally symmetrical distribution of the first lateral structure 2 and the second lateral structure 5, and a centrally symmetrical distribution of the first argument unit 3 and the second argument unit 4, then the first included angle 14 and the second included angle 15 are the same, that is, attached... Figure 3 In this context, angles α and β are the same.

[0042] In this embodiment, the angles of the first included angle 14 and the second included angle 15 are set in the range of 90°-120°, that is, the angles α and β are set in the range of 90°-120°.

[0043] Preferably, the angles of the first included angle 14 and the second included angle 15 can be set within the range of 100°-110°, that is, the angles α and β can be set within the range of 100°-110°.

[0044] In this embodiment, the specific angles of the first included angle 14 and the second included angle 15 can be optimized according to the performance parameters of the wheel spokes.

[0045] In addition, in this embodiment, the first support structure 2 includes a first support 21 and a first support pad 22. The first support 21 is disposed on the outer side of the first supporting fiberglass member 11, and the first support pad 22 is disposed on the inner side of the first supporting fiberglass member 11. The second support structure 51 includes a second support 51 and a second support pad 52. The second support 51 is disposed on the outer side of the second supporting fiberglass member 13, and the second support pad 52 is disposed on the inner side of the second supporting fiberglass member 13.

[0046] The first radiating unit 3 includes a first nose connector 31 and a first nose fabric layer 32. The first nose connector 31 is disposed on the inner side of the opposite ends of the first supporting fiberglass member 11 and the transition fiberglass member 12, and the first nose fabric layer 32 is disposed on the outer side of the opposite ends of the first supporting fiberglass member 11 and the transition fiberglass member 12. The second radiating unit 4 includes a second nose connector 41 and a second nose fabric layer 42. The second nose connector 41 is disposed on the inner side of the opposite ends of the second supporting fiberglass member 13 and the transition fiberglass member 12, and the second nose fabric layer 42 is disposed on the outer side of the opposite ends of the second supporting fiberglass member 13 and the transition fiberglass member 12.

[0047] This can also be understood as follows: the inner surfaces of the opposite ends of the first supporting fiberglass member 11 and the transition fiberglass member 12 are connected by the first nose connector 31, the outer surfaces of the opposite ends of the first supporting fiberglass member 11 and the transition fiberglass member 12 are connected by the first nose fabric layer 32, the inner surfaces of the opposite ends of the second supporting fiberglass member 13 and the transition fiberglass member 12 are connected by the second nose connector 41, and the outer surfaces of the opposite ends of the second supporting fiberglass member 13 and the transition fiberglass member 12 are connected by the second nose fabric layer 42.

[0048] In this embodiment, the fiberglass reinforced structure 1 is embedded in the first cusp structure 2, the first cusp unit 3, the second cusp unit 4 and the second cusp structure 5 in an inlay manner, and both ends of the fiberglass reinforced structure 1 extend to the opposite ends of the first cusp structure 2 and the second cusp structure 5.

[0049] In a preferred embodiment, the thickness of the rubber layer on the surface of the glass fiber reinforced structure 1 is greater than or equal to 0.1 mm. Preferably, the thickness of the rubber layer on the surface of the glass fiber reinforced structure 1 is 0.2-0.3 mm.

[0050] In this embodiment, the glass fiber reinforced structure 1 is made of continuous glass fiber and epoxy vinyl ester resin composite, thereby providing radial stiffness for the overall spoke structure and maintaining the overall shape of the spokes. It is the overall skeleton structure of the two-unit centrally symmetrical spoke structure. Combined with the centrally symmetrically distributed first and second branch structures 2 and 5, as well as the first and second spoke units 3 and 4, it achieves a load-bearing effect, thereby avoiding uneven stress distribution on the adhesive surface, significantly reducing unidirectional tearing force, enhancing the fatigue strength of the adhesive surface, and greatly alleviating the problem of poor adhesion fatigue strength between the spokes and tread of non-pneumatic tires, which easily leads to tearing damage and spoke failure. This enhances the bending and torsional resistance of the spokes and improves their stability.

[0051] Specifically, such as Figure 4-5 As shown, the two-unit centrally symmetrical spoke structure provides stronger load-bearing capacity, thereby effectively reducing the tensile stress at the first corner structure 2 and the second corner structure 5. This reduces the tensile stress of the rubber at the first corner structure 2 and the second corner structure 5 to 0.098 MPa, approximately 1 / 5 of that in existing spokes, significantly enhancing the fatigue resistance of the rubber and further improving the fatigue life of the spokes. Notably, the rubber exhibits better resistance to compressive fatigue than to tensile fatigue.

[0052] Example 2

[0053] This embodiment discloses a two-unit centrally symmetric spoke structure for non-pneumatic tires, which further discloses another connection structure of glass fiber reinforced structure 1 based on embodiment 1.

[0054] In this embodiment, the specific shape of the glass fiber reinforced structure 1 is as follows: the first supporting glass fiber member 11 and the first end of the transition glass fiber member 12 are connected at a first angle 14 along the first direction, and the second supporting glass fiber member 13 and the second end of the transition glass fiber member 12 are connected at a second angle 15 along the second direction.

[0055] The first supporting fiberglass component 11 and the transition fiberglass component 12, after being connected, form a V-shaped structure that is not connected, and the second supporting fiberglass component 13 and the transition fiberglass component 12 also form a V-shaped structure that is not connected.

[0056] In this embodiment, similarly, the first radiating unit 3 includes a first nose connector 31 and a first nose fabric layer 32. The first nose connector 31 is disposed on the inner side of the opposite ends of the first supporting fiberglass member 11 and the transition fiberglass member 12, and the first nose fabric layer 32 is disposed on the outer side of the opposite ends of the first supporting fiberglass member 11 and the transition fiberglass member 12. The second radiating unit 4 includes a second nose connector 41 and a second nose fabric layer 42. The second nose connector 41 is disposed on the inner side of the opposite ends of the second supporting fiberglass member 13 and the transition fiberglass member 12, and the second nose fabric layer 42 is disposed on the outer side of the opposite ends of the second supporting fiberglass member 13 and the transition fiberglass member 12.

[0057] This can also be understood as follows: the inner surfaces of the opposite ends of the first supporting fiberglass member 11 and the transition fiberglass member 12 are connected by the first nose connector 31, the outer surfaces of the opposite ends of the first supporting fiberglass member 11 and the transition fiberglass member 12 are connected by the first nose fabric layer 32, the inner surfaces of the opposite ends of the second supporting fiberglass member 13 and the transition fiberglass member 12 are connected by the second nose connector 41, and the outer surfaces of the opposite ends of the second supporting fiberglass member 13 and the transition fiberglass member 12 are connected by the second nose fabric layer 42.

[0058] In other words, the first supporting fiberglass component 11 and the transition fiberglass component 12 are connected by the first argument unit 3, and the second supporting fiberglass component 13 and the transition fiberglass component 12 are connected by the second argument unit 4, thereby realizing the sequential connection of the first supporting fiberglass component 11, the transition fiberglass component 12 and the second supporting fiberglass component 13 into a whole, and the connected fiberglass reinforced structure 1 is Z-shaped.

[0059] In this embodiment, the fiberglass reinforced structure 1 is embedded in the first cusp structure 2, the first cusp unit 3, the second cusp unit 4 and the second cusp structure 5 in an inlay manner, and both ends of the fiberglass reinforced structure 1 extend to the opposite ends of the first cusp structure 2 and the second cusp structure 5.

[0060] Example 3

[0061] This embodiment discloses a two-unit centrally symmetric spoke structure for non-pneumatic tires, which further discloses another structure of glass fiber reinforced structure 1 based on embodiment 1 or 2.

[0062] In this embodiment, the opposite ends of the first supporting fiberglass member 11 and the transition fiberglass member 12 are bent towards the outer side of the first supporting fiberglass member 11 to form a third included angle 16, or angle γ. The opposite ends of the second supporting fiberglass member 13 and the transition fiberglass member 12 are bent towards the outer side of the second supporting fiberglass member 13 to form a fourth included angle 17, or angle δ. See [reference needed] Figure 3 As shown.

[0063] Furthermore, since the first support structure 2 and the second support structure 5 are respectively located at the opposite ends of the first supporting fiberglass component 11 and the second supporting fiberglass component 13, in order to achieve a centrally symmetrical distribution of the first support structure 2 and the second support structure 5, the third included angle 16 and the fourth included angle 17 are the same, that is, attached... Figure 3 The angles γ and δ are the same.

[0064] In this embodiment, bending the opposite ends of the first supporting fiberglass member 11 and the second supporting fiberglass member 13 can enhance the bonding strength between the first corner structure 2 and the second corner structure 5 and the fiberglass reinforced structure 1, respectively.

[0065] Example 4

[0066] This embodiment discloses a non-pneumatic tire, which includes an outer tire tread, a rim that matches the outer tire tread, and a plurality of two-unit centrally symmetrical spokes as described in Embodiment 1. The plurality of two-unit centrally symmetrical spokes are distributed around the rim between the outer tire tread and the rim.

[0067] Specifically, the first supporting fiberglass component 11 of the two-unit centrally symmetrical wheel spoke is connected to the outer surface of the wheel hub through the first support structure 2, and the second supporting fiberglass component 13 is connected to the radial inner surface of the outer tire tread through the second support structure 5.

[0068] In this embodiment, the specific structure of the two-unit centrally symmetrical wheel spokes is described in Embodiment 1, and will not be repeated in this embodiment.

[0069] The non-pneumatic tire of this embodiment adopts a two-unit centrally symmetrical spoke structure. During its use, the sum of the internal forces and torques on the bonding surface are zero when compressed vertically. This avoids uneven stress distribution on the adhesive surface, significantly reduces unidirectional tearing force, and enhances the fatigue strength of the adhesive surface. It greatly alleviates the problem of poor adhesion fatigue strength between the spokes and the tread of the non-pneumatic tire, which easily leads to tearing damage and spoke failure. At the same time, it enhances the bending and torsional resistance of the non-pneumatic tire, improves the stability of the non-pneumatic tire, and further improves the fatigue life of the non-pneumatic tire.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
