Description

Technical Field

[0001] The present application relates to a new energy tire with high - efficiency heat dissipation, belonging to the technical field of tires. Background Art

[0002] New energy vehicles use non - fossil fuels as energy sources, having the advantages of high energy utilization efficiency, low emissions or zero emissions, simple structure, low noise, and wide energy raw materials, which is of great significance for environmental protection. Although the power source of new energy vehicles is different from that of traditional vehicles using fossil fuels, they still have the structures used in traditional vehicles, such as the suspension part, braking system, and transmission system of the engine. At the same time, new energy vehicles have excellent performance, good acceleration performance, high top speed, and high requirements for the components of each vehicle system.

[0003] During the driving process of existing new energy vehicles, the heat dissipation of the tires is relatively slow, which leads to an increase in rolling resistance, an increase in fuel consumption, and is not conducive to environmental protection. In severe cases, it may even cause safety accidents. Therefore, currently, the method of opening holes on the tire tread is usually used for heat dissipation. Although it can play a certain role in heat dissipation, the heat dissipation holes will cause local stress concentration and cracks, and the expansion of the cracks will ultimately lead to tire scrapping, thus reducing the tire life.
