Problems solved by technology

[0003] The non-pneumatic tires currently used in the market usually use super-elastic polymer materials, such as rubber, polyurethane, etc. Heat is generated, and it is difficult to dissipate it. The problem of internal heat generation in this material is a major obstacle to the development of non-pneumatic tires

Embodiment 1

[0052] like Figure 1-4 As shown, this embodiment provides a heat exchange tire, which includes a tire body 1 , and the tire body 1 has a filler cavity 10 inside, and the filler cavity 10 is filled with a phase change heat absorbing structure 2 . The phase-change heat-absorbing structure 2 includes a phase-change material 21 , and the phase-change material 21 can undergo a phase change when the tire is running, and absorb the heat of the tire body 1 during the phase change process.

[0053] The heat-exchange tires in this embodiment are mainly aimed at non-pneumatic tires. Since the non-pneumatic tires need to ensure that they can bear the same load as the traditional pneumatic tires, special polymer materials need to be used, and the internal heat generation of this type of material is serious. , and cannot be distributed in a short time, and the continuous running time is very limited, so it is more necessary to set up a cooling or cooling mechanism to relieve its heat generat...

Embodiment 2

[0085] like Figure 5 As shown, this embodiment provides a heat exchange tire, and the structure of the heat exchange tire is basically the same as that of the heat exchange tire in the first embodiment, and the difference lies in the arrangement of the phase change heat absorption structure 2 .

[0086] In this embodiment, the heat-exchange tire further includes a wheel hub 4 , which is arranged on the inner ring of the tire body 1 . The inside of the wheel hub 4 has a heat exchange cavity 41 , and the heat exchange cavity 41 communicates with the filler cavity 10 inside the tire body 1 .

[0087] Since the wheel hub 4 used in the tire is made of metal, usually aluminum alloy, with high thermal conductivity, it can be quickly cooled by air, which will quickly release the heat absorbed by the phase change material 21. Therefore, by connecting the inside of the tire and the inside of the wheel hub 4 , so that the phase change material 21 can flow between the inside of the tire...

Embodiment 3

[0089] like Figure 6-12 As shown, this embodiment provides a heat exchange tire, the arrangement of the internal phase change heat absorbing structure 2 of the tire is basically the same as that of the heat exchange tire in the first embodiment, and the difference lies in the structural shape of the applied tire.

[0090] In this embodiment, the heat exchange tire is a hollow tire structure, such as a honeycomb tire, a spoke tire, etc. For details, please refer to Image 6 and Figure 7 shown.

[0091] The heat exchange tire is designed as a hollow structure, which has less material than a solid tire and can accelerate heat dissipation, but the improvement of heat dissipation effect is limited, so it is still necessary to combine the phase change heat absorption structure 2 to ensure the cooling effect. Moreover, since the hollow structure needs to bear the same load as a solid tire, the polymer materials used are stronger than rubber, such as polymer elastomers, but the en...

Abstract

The invention relates to the technical field of tire design and manufacturing, in particular to a heat exchange tire and a vehicle. The heat exchange tire comprises a tire body, a filler cavity is formed in the tire body, and the filler cavity is filled with a phase change heat absorption structure; the phase-change heat absorption structure comprises a phase-change material, and the phase-change material can generate phase change in the running state of the tire and absorb heat of the tire body in the phase change process. According to the heat exchange tire and the vehicle, the filler cavity is formed in the tire body, the filler cavity is filled with the phase change heat absorption structure, heat generated in the running process of the tire is absorbed, the phase change heat absorption structure comprises the phase change material, and the heat exchange effect of the tire is improved by utilizing the characteristic that the phase change material can absorb heat through the phase change process. According to the tire cooling device, heat absorption of the tire is achieved, heat in the tire can be dissipated without the help of an external structure, the tire cooling effect can be achieved, and the structure is simpler on the basis that the tire cooling effect is guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of tire manufacturing, and in particular, to a heat exchange tire and a vehicle. Background technique [0002] With the development of automobile intelligence, electrification, networking and sharing, traditional pneumatic tires are difficult to meet the development needs of future vehicles in terms of safety and driving performance. Non-pneumatic tires break the traditional pneumatic tires in structure, material On the premise of ensuring safety, it has the potential to further improve the driving performance and become the future development direction of the tire industry. [0003] Non-pneumatic tires currently used in the market usually use super-elastic polymer materials, such as rubber, polyurethane, etc. However, whether it is rubber, polyurethane or other polymer materials, long-term operation under high frequency or high load is very easy to produce internal Heat is generated, and it is dif...
