Description

Technical Field

[0001] This utility model relates to the field of automotive tire technology, specifically to an asymmetric heat dissipation and flow guiding tire. Background Technology

[0002] In the field of tire technology, balancing heat dissipation performance and mechanical performance has always been a core technical challenge. Traditional tires mostly adopt a symmetrical heat dissipation structure design, with its longitudinal tread grooves and heat dissipation slots evenly distributed, which can meet basic heat dissipation requirements.

[0003] However, under high-speed driving or high-intensity working conditions, tires generate a lot of heat due to friction and deformation. The heat on the outside of the tire will naturally flow to the outside, while the heat on the inside of the tire will form a vortex heat retention. If the heat cannot be dissipated in time, it will lead to uneven distribution of the tread temperature gradient. The rubber in some areas (such as the tire shoulder) will age faster due to long-term overheating, which will seriously affect the tire's service life and safety.

[0004] Therefore, how to provide an asymmetric heat dissipation and flow guiding tire to overcome the defects in the existing technology is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To address this issue, this invention provides an asymmetric heat dissipation and flow-guiding tire to solve the problem in the prior art where, due to the formation of vortex heat retention on the inner side of the tire during high-speed operation, the uneven distribution of the tread temperature gradient leads to accelerated aging of the rubber compound in localized areas due to prolonged overheating, severely affecting the tire's service life and safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses an asymmetric heat dissipation and flow guiding tire, comprising:

[0008] The tire body has several longitudinal tread grooves on its surface;

[0009] A plurality of guide grooves are formed on the surface of the tire body, the guide grooves extending from the inside to the outside of the tire body, and the guide grooves penetrate each of the longitudinal grooves.

[0010] Several heat dissipation wires are disposed inside the tire body, with one end of each heat dissipation wire extending to the inner side of the tire body and the other end extending to the outer side of the tire body.

[0011] An aerogel insulation layer is wrapped around the outside of the heat dissipation filament;

[0012] Several heat dissipation holes are formed on the axial outer sidewall of the tire body.

[0013] Furthermore, the depth of the guide groove gradually decreases from the inside to the outside of the tire body.

[0014] Furthermore, the axial angle between the guide groove and the tire body is α, where 35°≤α≤45°.

[0015] Furthermore, the number of the guide grooves is six, and the six guide grooves are distributed in a circumferential array on the surface of the tire body.

[0016] Furthermore, the heat dissipation wire includes:

[0017] A copper core is disposed inside the tire body, with its two ends extending to the inner and outer sides of the tire body, respectively.

[0018] An aluminum cladding layer covers the outside of the copper core.

[0019] Furthermore, several of the heat dissipation wires are spaced apart along the outer wall of the tire body along the axial direction, with a spacing of 7.2 mm.

[0020] Furthermore, the heat dissipation holes are honeycomb-shaped and are arranged around the heat dissipation filaments.

[0021] Furthermore, the aerogel insulation layer is made of nano-silicon-based aerogel.

[0022] This utility model has the following advantages:

[0023] This invention utilizes guide grooves to create directional airflow channels during tire rotation, rapidly channeling heat accumulated on the inner side to the outer side. Compared to traditional symmetrical heat dissipation grooves, this significantly reduces vortex heat retention and improves heat dissipation efficiency. By incorporating heat dissipation wires, an efficient heat conduction path is created within the tire, ensuring rapid heat transfer from the inner to the outer side, resulting in a more uniform tread temperature distribution and preventing localized rubber aging. The aerogel insulation layer covering the heat dissipation wires prevents heat from the inner side of the tire from being transferred into the tire interior during conduction, creating complete isolation between the high-temperature heat dissipation wires and the tire body, preventing strength loss due to heat aging of the rubber. The honeycomb-shaped heat dissipation hole array reduces the tire wall thickness while maintaining wall strength, enhancing heat dissipation capacity and resulting in a more uniform tread temperature distribution, further preventing localized rubber aging. By embedding several heat dissipation wires into the tire body at a 7.2mm axial spacing, a highly efficient heat conduction network is constructed. Combined with the outer honeycomb-shaped heat dissipation hole array, this significantly improves the overall uniformity of the tread temperature distribution. Attached Figure Description

[0033] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Please refer to Figures 1-6 The asymmetric heat dissipation and flow guiding tire disclosed in this utility model will now be described. This utility model consists of 5 parts, as follows: Figure 1 , Figure 2 , Figure 3 As shown, the tire body includes a tire body 1, guide grooves 3, heat dissipation wires 4, an aerogel insulation layer 5, and heat dissipation holes 6. The surface of the tire body 1 is provided with a number of longitudinal grooves 2, and a number of guide grooves 3 are provided on the surface of the tire body 1. The guide grooves 3 extend from the inside to the outside of the tire body 1 and penetrate through each longitudinal groove 2. A number of heat dissipation wires 4 are provided inside the tire body 1. One end of the heat dissipation wire 4 extends to the inside of the tire body 1, and the other end of the heat dissipation wire 4 extends to the outside of the tire body 1. The aerogel insulation layer 5 covers the outside of the heat dissipation wires 4, and a number of heat dissipation holes 6 are provided on the axial outer sidewall of the tire body 1.

[0035] In this embodiment, the inner side of the tire body 1 is the driving side, and the outer side of the tire body 1 is the non-driving side. The longitudinal tread groove 2 is a common tread groove on tires in the prior art, and the guide tread groove 3 has the following shape. Figure 1 , Figure 2 As shown, the guide grooves 3 pass laterally through each longitudinal groove 2. Preferably, the axial angle between the guide grooves 3 and the tire body 1 is α, where 35°≤α≤45°. By setting the guide grooves 3, a directional airflow channel is formed when the tire rotates, quickly guiding the heat accumulated on the inner side to the outer side. Compared with the heat dissipation grooves of the traditional symmetrical structure, this significantly reduces the phenomenon of vortex heat retention and improves heat dissipation efficiency. Preferably, there are six guide grooves 3, which are distributed in a circumferential array on the surface of the tire body 1.

[0036] The location of heat sink 4 is as follows Figure 3 As shown, the heat dissipation wire 4 runs through both sides of the tire, with both ends located at the tire shoulder of the tire body 1. Heat from the inside of the tire can be transferred to the outside of the tire through the heat dissipation wire 4, further reducing the temperature of the inside of the tire. Preferably, the diameter of the heat dissipation wire 4 is 0.5-0.8 mm. By setting the heat dissipation wire 4, an efficient heat conduction path is formed inside the tire, ensuring that heat is quickly conducted from the inside of the tire to the outside, making the tread temperature distribution more uniform and avoiding localized aging of the rubber compound.

[0037] The aerogel insulation layer 5 is wrapped around the outside of the heat dissipation wire 4. The aerogel insulation layer 5 is made of nano-silica-based aerogel and can withstand temperatures up to 650℃. By wrapping the heat dissipation wire 4 with the aerogel insulation layer 5, heat from the inside of the tire is prevented from being conducted into the tire's interior through the heat dissipation wire 4, thus completely isolating the high-temperature heat dissipation wire 4 from the interior of the tire body 1 and preventing the rubber from weakening due to heat aging.

[0038] The location of heat dissipation hole 6 is as follows Figure 1 , Figure 2 As shown, the heat dissipation holes 6 are located on the axial outer sidewalls of both sides of the tire body 1, specifically at the tire shoulder position. Preferably, the heat dissipation holes 6 are honeycomb-shaped and arranged around the heat dissipation wires 4. The honeycomb-shaped heat dissipation holes 6 can reduce the thickness of the tire sidewall while maintaining its strength, which is beneficial for tire heat dissipation. By setting an array of honeycomb-shaped heat dissipation holes 6, the tire sidewall strength is maintained while the tire sidewall thickness is reduced, enhancing the heat dissipation capacity of the tire sidewall, making the tread temperature distribution more uniform, and avoiding localized aging of the rubber compound.

[0039] like Figure 5 , Figure 6 As shown, the depth of the guide groove 3 gradually decreases from the inner side to the outer side of the tire body 1. The specific shape of the guide groove 3 is as follows: Figure 6 As shown, the guide groove 3 adopts a tapered guide wall, with the wall thickness decreasing from 3.2mm to 1.8mm. The depth of the guide groove 3 decreases from the inside to the outside, optimizing airflow distribution and making it more conducive to the flow of heat from the inside of the tire to the outside.

[0040] like Figure 3 , Figure 4 As shown, the heat dissipation wire 4 includes a copper core 61 and an aluminum cladding layer 62. The copper core 61 is disposed inside the tire body 1, and the two ends of the copper core 61 extend to the inner and outer sides of the tire body 1, respectively. The aluminum cladding layer 62 covers the outer side of the copper core 61. Preferably, a plurality of heat dissipation wires 4 are spaced apart along the outer wall of the tire body 1 in the axial direction, with a spacing of 7.2 mm.

[0041] In this embodiment, the heat dissipation wire 4 is made of a copper core 61 wrapped with an aluminum cladding layer 62, which enables the heat dissipation wire 4 to achieve a thermal conductivity of 398 W / m·K. By embedding several heat dissipation wires 4 into the tire carcass at an axial spacing of 7.2 mm, a highly efficient heat conduction network is constructed. Combined with the outer honeycomb heat dissipation hole array 6, the overall temperature distribution uniformity of the tire tread is greatly improved.

[0042] In one specific embodiment, a tire for use in an electric passenger vehicle is provided;

[0043] Set 6 42° oblique flow guide grooves 3 (groove depth 8.2mm, groove width 4.5mm) per 10cm;

[0044] Six ventilation holes, arranged in a honeycomb matrix, measuring 3.5 × 3.5 mm. 2 The honeycomb wall thickness is 1.2mm;

[0045] Heat dissipation wire 4 network: copper core 61 (diameter 0.6mm) + aluminum cladding layer 62 (thickness 0.1mm), axial spacing 7.2mm.

[0046] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
