Power generation wheel

Technical Field

Background

Except for rail cars and crawler cars, most of the wheels of the prior cars are provided with inflatable tires, and the wheels consist of hubs and inflatable tires. The deformation of the inflatable tire is elastic deformation because the deformation is recovered along with the rotation of the wheel because the centripetal shrinkage deformation is larger than the deformation along other directions when the inflatable tire is extruded and deformed at the position contacting with the road surface by the gravity of the vehicle. The elastic deformation of the pneumatic tire is necessary because it functions to absorb shock and stabilize the running of the vehicle and protect the road surface, but consumes energy. The inflatable tire is often inflated in use, the tire burst is sometimes caused, the tire burst is more easily caused when the environmental temperature is high, and the vehicle damage and traffic accidents are possibly caused by the tire burst.
