Abstract

An automatic tire inflation ring which adopts pure physical principles and has no energy consumption comprises a gasket ring, a clamping ring, a pressing ring, an air acquisition pipe and a check valve and is mounted in a position where the inner side of a hub edge is combined with the outer side of a tire port, wherein the air acquisition pipe is connected with the check valve, and an air inlet nozzle of the check valve penetrates through a hub and is communicated with a tire air bin. When the tire of a vehicle is short of air (pressure) and deforms during driving, the pressing ring is forced to downward extrude the air acquisition pipe to form airtightness under the opposite acting force supported by the gasket ring and the clamping ring by using outward side action force on the side surface of the tire, and when the tire rotates, air in the air acquisition pipe gathers in the same direction to gradually form high pressure which breaks though the check valve and enters the tire air bin to realize automatic air inflation in real time during shortage of air (pressure) of the tire; and when the tire is inflated to recover the normal form (rated pressure), the pressing ring loses pressure of the gasket ring and the clamping ring and stops inflation after return, and the air pressure of the tire is normal in the vehicle driving process, and the traffic safety is guaranteed.
