Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a tire, wheel, and vehicle. Background Technology

[0002] Vehicle wheels and tires are usually equipped with treads. These treads increase the friction between the tire and the ground, thereby improving the tire's grip and preventing the wheels from slipping.

[0003] In related technologies, materials such as rubber are typically used to process the tread pattern and other structures of the tire, and the tire is assembled using equipment. Then, the tire is processed through a vulcanization process to shape the tire.

[0004] However, as vehicles are driven for extended periods, the tire treads gradually wear down, reducing the tire's grip and making the wheels more prone to slipping, thus affecting vehicle safety. Summary of the Invention

[0005] The purpose of this application is to provide a tire, wheel, and vehicle designed to solve the problem of wheel slippage after wear.

[0006] In a first aspect, a tire is provided, comprising a support layer, an elastic compression layer, and a contact layer arranged radially along the tire, the support layer being adapted to be connected to a wheel rim. The contact layer has a first tread pattern for contacting the ground. The elastic compression layer is compressed between the support layer and the contact layer, and the surface of the elastic compression layer facing the contact layer has a second tread pattern in a compressed state.

[0007] According to the above technical means, during the vehicle's operation, the first tread pattern of the contact layer can first contact the ground to ensure that the tire has sufficient grip. As the vehicle travels for a long time, after the first tread pattern of the contact layer wears down and the tire's grip decreases, the support layer can provide support for the elastic compression layer, allowing the elastic compression layer to break through the contact layer and extend to a free state. At this time, the second tread pattern on the surface of the elastic compression layer can contact the ground.

[0008] Since the second tread pattern does not contact the ground when it is in a compressed state, the elastic compression layer that has stretched to a free state can replace the contact layer, and the second tread pattern can replace the first tread pattern in contacting the ground, thereby restoring a certain amount of tire grip, ensuring the tire's grip effect, preventing wheel slippage, and ensuring safe driving of the vehicle.

[0009] With the above setup, the elastic compression layer, once extended to its free state, can replace the contact layer in contact with the ground to ensure tire grip. This eliminates the need to replace the tire, extending its lifespan. Furthermore, compared to repairing tires through vulcanization, the elastic compression layer allows tire grip to be restored simply by extending it to its free state, simplifying tire maintenance and facilitating vehicle use.

[0010] In some embodiments, along the radial direction of the tire, the dimension of the first tread when it is not worn is the first dimension, the dimension of the second tread in its free state is the second dimension, and the ratio of the second dimension to the first dimension is greater than or equal to 0.85.

[0011] According to the above-mentioned technical means, when the first tread wears out, the elastic compression layer can be stretched to a free state so that the size of the second tread can be restored to 85% or more of the maximum size of the first tread, thereby restoring a certain amount of tire grip and ensuring the tire's grip performance.

[0012] In some embodiments, the elastic compression layer includes an elastic material layer and a support, the support being disposed within the elastic material layer for supporting the elastic material layer. The elastic material layer has a second pattern, and the support is capable of deformation to lift the elastic material layer.

[0013] Based on the aforementioned technical means, by placing the bracket within the elastic material layer, the bracket can provide support to the elastic material layer, ensuring its structural strength when in a free state and guaranteeing the tire's support effect on the vehicle. Simultaneously, by deforming the bracket to lift the elastic material layer, the elastic compression layer can be allowed to extend normally to a free state, thereby ensuring the tire's normal function.

[0014] In some embodiments, the bracket is made of shape memory metal. And / or, the bracket is elongated and extends in a wavy shape along the circumference of the tire.

[0015] Based on the aforementioned technical means, after the contact layer wears down, the shape memory effect of the shape memory metal allows the support to automatically extend. By automatically supporting the elastic material layer, the elastic compression layer can be ensured to extend to a free state in a timely manner. Moreover, compared to the support extending directly along the circumference of the tire, after the first tread wears down, the support can more easily extend along the radial direction of the tire to support the elastic material layer. This ensures that the support can properly support the elastic material layer, thereby guaranteeing the normal function of the elastic compression layer.

[0016] In some embodiments, the tire further includes a support member that surrounds the support layer along the circumference of the tire and is supported between the resilient compression layer and the support layer.

[0017] According to the above technical means, the support member is supported between the elastic compression layer and the support layer to prevent the support layer from deforming after being squeezed by the elastic compression layer. In this way, the support layer and the support member can provide more stable support for the elastic compression layer, so as to ensure that the elastic compression layer expands towards the contact layer, and ensure that the second pattern can make normal contact with the ground, thereby ensuring the normal function of the elastic compression layer.

[0018] In some embodiments, the support includes a plurality of struts, each extending axially along the tire. The struts are spaced apart circumferentially along the tire and are all supported between an elastic compression layer and a support layer.

[0019] According to the above technical means, by arranging multiple pillars at intervals with gaps between adjacent pillars, multiple gaps can provide leeway for the elastic compression layer to extend, allowing the elastic compression layer to extend a certain distance toward the support layer. This can avoid excessive stress on the side of the elastic compression layer near the support layer, and further ensure the normal extension and normal function of the elastic compression layer.

[0020] In some embodiments, the tire further includes a limiting pad that surrounds the support member along the circumference of the tire and is supported between the resilient compression layer and the support member.

[0021] According to the above technical means, by setting a limiting pad, the limiting pad can buffer the elastic compression layer during the process of the elastic compression layer extending to the free state, so as to avoid excessive impact of the elastic compression layer on the support layer, thereby avoiding damage to the elastic compression layer or the support layer, and ensuring the normal function of the elastic support layer and the support layer.

[0022] In some embodiments, the shape of the second pattern is consistent with the shape of the first pattern.

[0023] According to the above-mentioned technical means, when the second tread pattern is in a free state, the shape of the tire can be similar to or consistent with the shape of the tire when the first tread pattern is not worn. This makes the tire's grip effect when the second tread pattern is in a free state close to or consistent with the tire's grip effect when the first tread pattern is not worn. This can avoid the difference in tire grip effect caused by the difference between the shape of the second tread pattern and the shape of the first tread pattern, so as to further ensure the stable operation of the vehicle.

[0024] Secondly, a wheel is also provided, including the aforementioned tire.

[0025] Thirdly, a vehicle is also provided, including the aforementioned wheels. Attached Figure Description

[0028] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0029] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0030] Vehicle tires typically have tread patterns to improve grip and prevent wheel slippage, thus ensuring safe driving. However, as vehicles are driven for extended periods, these tread patterns gradually wear down, reducing their size and consequently decreasing grip, making the wheels more prone to slippage.

[0031] In related technologies, after the tread pattern on the tire surface wears down, new tires are usually replaced, or the tread pattern on the tire surface is repaired through a vulcanization process to ensure the safe operation of the vehicle. However, this requires wheel maintenance, which affects the use of the vehicle.

[0032] To solve the above problems, such as Figure 1 and Figure 2 As shown, this application provides a tire 10. Along the radial direction of the tire 10, the tire 10 includes a support layer 3, an elastic compression layer 2 and a contact layer 1 arranged in sequence. The support layer 3 is adapted to be connected to the rim of the wheel 100.

[0033] The contact layer 1 has a first pattern 11 for contacting the ground.

[0034] The elastic compression layer 2 is compressed between the support layer 3 and the contact layer 1, and the surface of the elastic compression layer 2 facing the contact layer 1 is provided with a second pattern in the compressed state.

[0035] It should be noted that the elastic compression layer 2 being compressed between the support layer 3 and the contact layer 1 means that the elastic compression layer 2 is located between the support layer 3 and the contact layer 1 and is in a compressed state.

[0036] Thus, during the driving of vehicle 1000, the first tread pattern 11 of contact layer 1 can first contact the ground to ensure that tire 10 has sufficient grip (such as the wet braking performance of tire 10 and the snow traction of tire 10). As vehicle 1000 drives for a long time, after the first tread pattern 11 of contact layer 1 wears down and the grip of tire 10 decreases, support layer 3 can provide support for elastic compression layer 2, so that elastic compression layer 2 can break through contact layer 1 and extend to a free state. At this time, the second tread pattern on the surface of elastic compression layer 2 can contact the ground.

[0037] Since the second tread pattern does not contact the ground when it is in a compressed state, the elastic compression layer 2, which is stretched to a free state, can replace the contact layer 1, and the second tread pattern can replace the first tread pattern 11 to contact the ground, thereby restoring a certain grip of the tire 10, ensuring the grip effect of the tire 10, avoiding wheel 100 slippage, and ensuring the safe driving of the vehicle 1000.

[0038] With the above configuration, the elastic compression layer 2, after being extended to a free state, can replace the contact layer 1 to contact the ground, thus ensuring the grip of the tire 10. This eliminates the need to replace the tire 10, extending its service life. Furthermore, compared to repairing the tire 10 through a vulcanization process, the elastic compression layer 2 only needs to be extended to a free state to restore the tire 10's grip. This simplifies the tire 10 maintenance process and facilitates the use of the vehicle 1000.

[0039] It should be noted that the free state of the elastic compression layer 2 refers to the state of the elastic compression layer 2 when it is not compressed.

[0040] For example, the number of elastic compression layers 2 can be one, or the tire 10 can also include multiple elastic compression layers 2, which are arranged sequentially from the inside to the outside along the radial direction of the tire 10.

[0041] Since the second pattern is located in the elastic compression layer 2, and the elastic compression layer 2 is located between the contact layer 1 and the support layer 3, in order to ensure the contact effect between the second pattern and the ground, it is necessary to ensure that the size of the second pattern is close to the size of the first pattern 11 when the elastic compression layer 2 is in a free state.

[0042] Therefore, in some embodiments of this application, along the radial direction of the tire 10, the size of the first tread pattern 11 when it is not worn is the first size, the size of the second tread pattern in a free state is the second size, and the ratio of the second size to the first size is greater than or equal to 0.85.

[0043] For example, the ratio of the second dimension to the first dimension can be 0.85, 0.87, 0.89, 0.9, 0.93, 0.95, 0.96, 0.9, 1, etc.

[0044] In this way, when the first tread pattern 11 wears down, the elastic compression layer 2 can stretch to a free state and restore the size of the second tread pattern (i.e., the second size) to 85% or more of the maximum size of the first tread pattern 11 (i.e., the first size). This allows the size of the tread pattern on the surface of the tire 10 to be restored to close to the maximum size, thereby restoring a certain grip of the tire 10 and ensuring the grip effect of the tire 10.

[0045] At the same time, by leaving the elastic compression layer 2 in a free state, the size difference between the restored tire 10 and the other tires 10 of the vehicle 1000 can be reduced, thereby enabling the vehicle 1000 to drive more stably.

[0046] Here, "wearing of the first tread pattern 11" refers to the state where, along the radial direction of the tire 10, the ratio of the actual size of the first tread pattern 11 to its maximum size is greater than or equal to 0.55 and less than or equal to 0.6 (the above ratio can be 0.55, 0.56, 0.57, 0.58, 0.59, 0.6, etc.). At this time, the tire 10 has lower grip, and the structural strength of the contact layer 1 decreases after wear, reducing the constraint force on the elastic compression layer 2, making it easier for the elastic compression layer 2 to break through the contact layer 1.

[0047] It should be noted that when the elastic compression layer 2 is in a free state, the distance between the second tread pattern and the axis of the tire 10 can be equal to the distance between the first tread pattern 11 and the axis of the tire 10. That is, along the radial direction of the tire 10, the maximum size of the elastic compression layer 2 in a free state excluding the second tread pattern and the maximum size of the tire 10 in a non-worn state excluding the first tread pattern 11 are equal.

[0048] Alternatively, the size of tire 10 when the second tread pattern is in a free state can also be the same as the size of tire 10 when the first tread pattern 11 is not worn.

[0049] This allows the tire 10 to recover to a size close to its maximum size, ensuring that the second tread pattern can contact the ground, thereby further ensuring the grip of the tire 10 when the elastic compression layer 2 is in a free state.

[0050] In some embodiments, such as Figure 1 As shown, the elastic compression layer 2 includes an elastic material layer 21. The elastic material has a second pattern and is compressed between the contact layer 1 and the support layer 3. In order to ensure that the elastic material layer 21 can stretch normally so that the elastic compression layer 2 is in a free state, it is necessary to provide support for the elastic material layer 21.

[0051] Based on this, such as Figure 1 As shown, the elastic compression layer 2 also includes a support 22, which is disposed within the elastic material layer 21 and is used to support the elastic material layer 21. The support 22 can deform to support the elastic material layer 21.

[0052] By placing the bracket 22 inside the elastic material layer 21, the bracket 22 can provide support for the elastic material layer 21, thereby ensuring the structural strength of the elastic material layer 21 when it is in a free state and ensuring the support effect of the tire 10 on the vehicle 1000.

[0053] At the same time, the deformation of the bracket 22 lifts the elastic material layer 21, which enables the bracket 22 to drive the elastic material layer 21 to break through the contact layer 1, so as to ensure that the elastic compression layer 2 can be extended to a free state normally, thereby ensuring that the second tread can contact the ground after the first tread 11 is worn, and ensuring the normal function of the tire 10.

[0054] Of course, in some other embodiments, the elastic compression layer 2 may not be provided with the above-mentioned support 22, and the elastic compression layer 2 may be stretched to a free state by the elastic force of the elastic material layer 21 when it is compressed.

[0055] Based on this, in some embodiments, the support 22 can be made of shape memory metal.

[0056] In this way, when the first tread pattern 11 is not worn, the bracket 22 can be compressed together with the elastic material layer 21 between the contact layer 1 and the support layer 3. After the contact layer 1 is worn, the shape memory effect of the shape memory metal can make the bracket 22 automatically extend. This allows the bracket 22 to automatically lift the elastic material layer 21 without the need for a drive device to extend the bracket 22. This simplifies the structure of the tire 10 and makes the tire 10 easier to process and use.

[0057] At the same time, by automatically lifting the elastic material layer 21 by the bracket 22, it can be ensured that the elastic compression layer 2 extends to the free state in time, avoiding the risk of wheel 100 slipping due to the elastic compression layer 2 not extending to the free state in time, so as to ensure the safe operation of vehicle 1000.

[0058] It should be noted that shape memory metals require a certain temperature to produce shape memory effect. Taking the material of bracket 22 as a Ni-Ti-Cu ternary alloy (i.e., a ternary alloy material composed of nickel, titanium, and copper) as an example, when the first tread pattern 11 wears down, the friction between the tire 10 and the ground during the driving of vehicle 1000 will cause the temperature of the tire 10 to rise. When the temperature of bracket 22 reaches the temperature that can produce shape memory effect, bracket 22 can automatically extend and drive the elastic material layer 21 to break through the contact layer 1, so that the second tread pattern is in a free state and in contact with the ground.

[0059] The temperature at which the bracket 22 can produce a shape memory effect is greater than or equal to 55°C and less than or equal to 65°C, such as 55°C, 57°C, 59°C, 60°C, 62°C, 64°C, 65°C, etc. Specifically, when the speed of the vehicle 1000 is ≥40km / h, the temperature of the tire 10 is generally 50~80°C. The temperature at which the bracket 22 can produce a shape memory effect is within the above range, which can ensure that the bracket 22 produces a shape memory effect when the vehicle 1000 is driving normally.

[0060] Furthermore, the copper content in the Ni-Ti-Cu ternary alloy can be greater than or equal to 5% and less than or equal to 10%, such as 5%, 6%, 7%, 8%, 9%, 10%, etc.

[0061] In addition, Ni-Ti-Cu ternary alloys may also contain hafnium metal, with the hafnium content being greater than or equal to 3% and less than or equal to 8%, such as 3%, 4%, 5%, 6%, 7%, 8%, etc.

[0062] In some other embodiments, the support 22 can be made of other metals, such as copper, iron, alloys, etc., and the support 22 is extended by a driving device (such as a hydraulic rod, linear motor, etc.).

[0063] In some other embodiments, the tire 10 may also include a heating device, such as a heating sheet or a heating film, which heats the support 22 to cause the support 22 to extend after generating a shape memory effect, thereby actively driving the elastic compression layer 2 to extend to a free state.

[0064] In some embodiments, such as Figure 1 As shown, the bracket 22 is long and extends in a wave-like shape along the circumference of the tire 10.

[0065] With the above configuration, when the elastic compression layer 2 is in a compressed state, the bracket 22 can extend a certain length along the radial direction of the tire 10. Compared with the bracket 22 extending directly along the circumference of the tire 10, after the first tread 11 is worn, the bracket 22 can extend along the radial direction of the tire 10 more conveniently to support the elastic material layer 21. This ensures that the bracket 22 can properly support the elastic material layer 21, thereby ensuring the normal function of the elastic compression layer 2.

[0066] For example, along the radial direction of tire 10, the maximum distance between the bracket 22 and the axis of tire 10 is the first distance, and the minimum distance between the bracket 22 and the axis of tire 10 is the second distance. The difference between the first distance and the second distance (e.g.) Figure 1 H1 shown can be greater than or equal to 0.8 mm and less than or equal to 1.5 mm, for example, 0.8 mm, 0.9 mm, 1 mm, 1.2 mm, 1.4 mm, 1.5 mm, etc.

[0067] The bracket 22 has multiple first portions 221 arched away from the axis of the tire 10 and multiple second portions 222 arched towards the axis of the tire 10. The multiple second portions 222 are located on the side of the multiple first portions 221 closest to the axis of the tire 10. A second portion 222 connects two adjacent first portions 221. For two adjacent first portions 221, the point furthest from the axis of the tire 10 in one first portion 221 is designated as the first point, and the point furthest from the tire 10 in the other first portion 221 is designated as the second point. The distance between the first points and the second points along the circumference of the tire 10 is (e.g., ...). Figure 1 H2 shown can be greater than or equal to 4 mm and less than or equal to 8 mm, such as 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, etc.

[0068] The diameter of bracket 22 (e.g.) Figure 1 H3 shown can be greater than or equal to 0.3 mm and less than or equal to 0.5 mm, for example, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, etc.

[0069] After the support 22 generates a shape memory effect, it will stretch and lift the elastic material layer 21. The support 22 will also apply a certain pressure to the support layer 3 through the elastic material layer 21. The support layer 3 can provide support to the side of the elastic material layer 21 close to the support layer 3 to ensure that the elastic material layer 21 breaks through the contact layer 1.

[0070] The material of the support layer 3 may include rubber to facilitate the connection between the support layer 3 and the rim, but this will result in a poor support effect of the support layer 3 on the elastic compression layer 2.

[0071] To ensure that the elastic compression layer 2 can stretch to a free state normally, in some embodiments, such as Figure 1 As shown, the tire 10 also includes a support member 4. Along the circumference of the tire 10, the support member 4 surrounds the support layer 3 and is rigidly supported between the elastic compression layer 2 and the support layer 3.

[0072] With the above configuration, the support member 4, supported between the elastic compression layer 2 and the support layer 3, can prevent the support layer 3 from deforming after being squeezed by the elastic compression layer 2. In this way, the support layer 3 and the support member 4 can provide more stable support for the elastic compression layer 2, so as to ensure that the elastic compression layer 2 expands towards the contact layer 1, and ensures that the second pattern can make normal contact with the ground, thereby ensuring the normal function of the elastic compression layer 2.

[0073] In some other embodiments, the material of the support layer 3 may be set to include metal, etc., so as to improve the structural strength of the support layer 3 and provide more stable support for the elastic compression layer 2.

[0074] Specifically, in some embodiments, such as Figure 1 As shown, the support layer 3 may include a rubber layer 31 and a mesh structure 32. The mesh structure 32 is made of metal and is disposed within the rubber layer 31.

[0075] By setting a mesh structure 32 inside the rubber layer 31, the structural strength of the support layer 3 can be improved, thereby enabling the support layer 3 to provide more stable support for the elastic compression layer 2.

[0076] In some embodiments, such as Figure 1 As shown, the support member 4 includes a plurality of pillars 41, all of which extend along the axial direction of the tire 10. The plurality of pillars 41 are arranged at intervals along the circumference of the tire 10 and are all rigidly supported between the elastic compression layer 2 and the support layer 3.

[0077] With the above arrangement, multiple pillars 41 are rigidly supported between the elastic compression layer 2 and the support layer 3, which can support the elastic compression layer 2 so that the elastic compression layer 2 expands in the direction closer to the contact layer 1, ensuring the normal function of the elastic compression layer 2.

[0078] Meanwhile, by arranging multiple pillars 41 at intervals with gaps between adjacent pillars 41, multiple gaps can provide leeway for the elastic compression layer 2 to extend, allowing the elastic compression layer 2 to extend a certain distance toward the support layer 3. This can prevent excessive stress on the side of the elastic compression layer 2 near the support layer 3, and further ensure the normal extension and normal function of the elastic compression layer 2.

[0079] For example, the material of support column 41 can be iron, aluminum, alloy, etc.

[0080] For example, the cross-sectional shape of the support 41 can be square, elliptical, irregular, etc.

[0081] In some other embodiments, the support 4 may also include a support plate that extends circumferentially along the tire 10 and is rigidly supported between the elastic compression layer 2 and the support layer 3.

[0082] In some embodiments, such as Figure 1 As shown, the tire 10 also includes a limiting pad 5, which surrounds the support member 4 along the circumference of the tire 10 and is supported between the elastic compression layer 2 and the support member 4.

[0083] By setting the limiting pad 5, the limiting pad 5 can buffer the elastic compression layer 2 during the process of the elastic compression layer 2 extending to the free state, so as to avoid excessive impact of the elastic compression layer 2 on the support layer 3, thereby avoiding damage to the elastic compression layer 2 or the support layer 3, and ensuring the normal function of the elastic support layer 3 and the support layer 3.

[0084] At the same time, the limiting pad 5 also restricts the elastic compression layer 2 from extending towards the support layer 3, so as to ensure that the second pattern can make normal contact with the ground when the elastic compression layer 2 is in a free state, thereby further ensuring the normal function of the compression layer.

[0085] For example, the limiting pad 5 can be a rubber pad, silicone pad, etc.

[0086] In some other embodiments, the limiting pad 5 may also be disposed between the support member 4 and the support layer 3, thus providing cushioning for the elastic compression layer 2.

[0087] In some embodiments, the shape of the second pattern is consistent with the shape of the first pattern 11.

[0088] In this way, when the second tread pattern is in a free state, the shape of the tire 10 can be similar to or consistent with the shape of the tire 10 when the first tread pattern 11 is not worn. This makes the grip effect of the tire 10 when the second tread pattern is in a free state close to or consistent with the grip effect of the tire 10 when the first tread pattern 11 is not worn. This can avoid the difference in the grip effect of the tire 10 caused by the difference between the shape of the second tread pattern and the shape of the first tread pattern 11, so as to further ensure the stable operation of the vehicle 1000.

[0089] Of course, in some other embodiments, the shape of the second pattern may not be the same as the shape of the first pattern 11.

[0090] Based on the above, such as Figure 2As shown, this application also provides a wheel 100, including the aforementioned tire 10. By providing the elastic compression layer 2, the service life of the tire 10 can be extended, thereby extending the service life of the wheel 100, and improving the grip of the wheel 100 to prevent the wheel 100 from slipping.

[0091] like Figure 2 As shown, this application also provides a vehicle 1000, including the aforementioned wheel 100. By setting the tire 10 on the wheel 100, the wheel 100 can be prevented from slipping, thereby improving the stability and safety of the vehicle 1000 when driving.

[0092] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0093] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
