Description

Non-pneumatic tire for electric vehicle

Technical Field

The invention relates to the technical field of tires, in particular to an inflation-free tire for an electric vehicle.

Background

A tire is a ground-rolling circular ring-shaped elastic rubber article mounted on various vehicles or machines. Generally mounted on a metal rim, and is capable of supporting a vehicle body, buffering external impact, achieving contact with a road surface and ensuring the driving performance of a vehicle. Tires are often used under complex and severe conditions, which are subjected to various deformations, loads, forces and high and low temperature effects during running, and therefore must have high load-bearing, traction and cushioning properties. At the same time, high abrasion resistance and flexibility resistance, and low rolling resistance and heat build-up are also required. The birth and development of the automobile are great achievements of world science and technology progress, and are important footprints of human progress, so that the human beings are led into an automobile industry era from the carriage era. At the beginning of the automobile, in order to meet the requirements of comfort, operation stability and dynamic performance of the automobile, scientists continuously research and innovate, and continuously promote the progress and innovation of the tire industry.

The tire is used for the cover to establish on wheel hub at present to prevent that it from receiving wearing and tearing, and the tire of traditional electric motor car needs to be aerifyd, but just can't use when it receives sharp object to puncture, and the tire of present electric motor car is not fixed enough with the wheel hub block in addition, will rotate relatively when receiving emergency brake and knockover. Therefore, the invention provides an improvement to the non-pneumatic tire for the electric vehicle.
