Safe and fuel-efficient automatic pressure-regulating wheel

Abstract

A safe and fuel-efficient automatic pressure-regulating wheel is characterized in that the safe and fuel-efficient automatic pressure-regulating wheel comprises a sealing mechanism, a wheel mechanism and a pressure-regulating mechanism; the sealing mechanism is provided with a seal and a sealing ring; the wheel mechanism comprises a main wheel and an auxiliary wheel, wherein the main wheel is provided with a rim supporting ring while the auxiliary wheel is provided with an auxiliary rim supporting ring; and the pressure-regulating mechanism is provided with a bi-metal drum inside which a surge chamber is disposed, and a plenum chamber is arranged outside the bi-metal drum. The safe and fuel-efficient automatic pressure-regulating wheel has the advantages that with the functional material bi-metal drum as the tire pressure-regulating device, an air chamber of the tire is divided into the plenum chamber and the surge chamber, and when the temperature of the tire rises, an active layer on the inner wall of the bi-metal drum swells, and the drum waist of the bi-metal drum depresses toward the surge chamber along with the active layer, so that the volume of the plenum chamber of the tire increases, and tire pressure drops, and when the temperature of the tire drops, the active layer of the bi-metal drum shrinks, the drum waist of the bi-metal drum returns the plenum chamber, and the pressure in the plenum chamber recovers, so that the purposes of automatically regulating pressure, preventing a flat tire and driving with fuel-efficient effect are realized.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a safe and fuel-saving automatic pressure-regulating wheel hub. Background technique [0002] For the safe driving of vehicles and the prevention of violent tires caused by rising tire pressure, people use "vehicle safety valve", patent number: 200710092810.4 to replace ordinary valve; use "supporting wheel combination anti-riot tire rim", patent number: 201010526529.9 To support the wheel after a tire burst; the former is to decompress and exhaust, and the tire pressure will be reduced when the tire cools down, and it must be inflated when driving again, otherwise it will increase fuel consumption; the latter is a support wheel used after a tire burst; such as two The combination of the two can achieve safe driving, but it is not fuel-efficient. Contents of the invention [0003] In view of the above problems, the present invention provides a safe and fuel-saving autom...
