Description

A kind of non-pneumatic tire for electric vehicle

technical field

The utility model relates to the technical field of tires, in particular to an air-free tire for electric vehicles.

Background technique

Tires are annular elastic rubber products that roll on the ground and are assembled on various vehicles or machinery. Usually installed on the metal rim, it can support the body, buffer the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high bearing performance, traction performance, and cushioning performance. At the same time, high wear resistance and flex resistance, as well as low rolling resistance and heat build-up are also required. The birth and development of automobiles is a great achievement of the world's scientific and technological progress, and an important footprint of human progress, making human beings enter an era of automobile industry from the era of horse-drawn carriages. In the early days of automobiles, in order to meet the comfort, handling stability and power of automobiles, scientists continued to conduct research and innovation, and constantly promote the progress and innovation of the tire industry.

At present, the tire is used to set the wheel on the hub to prevent it from being worn out, while the tire of the traditional electric vehicle needs to be inflated, but it cannot be used when it is punctured by a sharp object. The coupling is not fixed enough, and it will turn out of the circle when it is suddenly braked. Therefore, we have improved this and proposed a pneumatic tire for electric vehicles.
