The invention relates to an automobile front wheel
flat tire protection device, which comprises two sets of
tire pressure signal output devices, a pressure information receiving device, a trigger, a
gas generator, a shaft, an energy dissipation belt, an air bag and a tire, wherein the
tire pressure signal output devices are arranged in grooves of hubs of two front wheels; the pressure informationreceiving device is connected with the trigger and the
gas generator, and the pressure information receiving device, the trigger and the
gas generator are jointly arranged on the lower front part of an automobile body; and the gas generator is communicated with the air bag. The automobile front wheel
flat tire protection device is characterized in that: the energy dissipation belt comprises an upper-section energy dissipation belt and a lower-section energy dissipation belt; the shaft comprises a shaft
barrel and a shaft neck; the upper-section energy dissipation belt is arranged on the shaftbarrel; the shaft neck on two sides of the shaft
barrel is provided with a
brake band; the upper-section energy dissipation belt is wound on the shaft
barrel; the lower-section energy dissipation belt is folded below the shaft barrel and above the air bag; and the tire is arranged above the lower-section energy dissipation belt. The automobile front wheel
flat tire protection device has the
advantage that: after a tire of a front wheel on one side of a high-speed running automobile is punctured, the automobile can be automatically prevented from deflecting or overturning, and can be stably stopped.
