Technical Field

The design relates to an energy recovery device, in particular to a wheel which stores lost rolling resistance energy for power generation, realizes energy conservation and is suitable for various running pavements.

Background

When the wheel rolls, the contact area of the tyre and the road surface generates normal and tangential interaction forces and corresponding deformation of the tyre and the supporting surface. Deformation of the elastic tire is dominant when the tire rolls on a hard road surface. At this time, the tyre has internal friction to generate elastic hysteresis loss, so that the tyre can not fully recover the work when being deformed. Particularly, when the vehicle speed rises, the rolling resistance is rapidly increased, the temperature is also rapidly increased, and when the vehicle speed reaches a certain height, standing wave phenomenon and even blasting can occur. Therefore, rolling resistance occupies a large part of the driving resistance of the automobile, so that great energy loss is caused, and the wheels are in dangerous working conditions during long-term high-speed driving.
