Pneumatic closed run-flat tire with air hole barrier fastener and spacer layer combination and its manufacturing method

Abstract

The invention discloses a pneumatic closed explosion-proof tire with the combination of an air hole type barrier fastener and an interval layer. The air hole type barrier fastener layer is sleeved in and in clip connection to a tire body; air outlets are formed in tire treads on two sides of the air hole type screening fastener layer; an interval layer kit is arranged in the air hole type barrier fastener layer in a sleeving manner, and a certain spacing is maintained to form an air releasing cavity communicating with an inner cavity of the tire body; after air in the tyre burst air releasing cavity is released, the air hole type barrier fastener layer and the interval layer can be closely attached to form a new tire body inner cavity to be continuously used. According to the pneumatic closed explosion-proof tire disclosed by the invention, the air hole type barrier fastener layer and the interval layer are mutually combined and matched for use so as to form a novel explosion-proof tire. When a tyre bursts, the air in the air releasing cavity is released from the air hole type barrier fastener layer, so that under the effect of atmospheric pressure, the interval layer and the air hole type barrier fastener layer are quickly attached so as to prevent the air from releasing timely, and after suffering from tyre burst, the driving vehicle can still maintain straight driving.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering and relates to vehicle tires, in particular to a pneumatic closed explosion-proof tire provided with a combination of an air hole barrier fastener and a spacer layer. Background technique [0002] Sudden tire blowouts during vehicle driving are a major safety hazard that plagues driving. For this reason, at least tens of thousands of people are injured or killed every year, especially on highways. 70% of car accidents are caused by car tire blowouts. . It has caused major economic losses to the country and brought irreparable tragedies to many families. According to the official authoritative scientific statistics, when the speed of the vehicle reaches 160 / hour and the tire blows out, the chances of survival of the drivers and passengers in the vehicle are zero. This tragic fact shows that the tire explosion protection is directly related to the life safety of the drivers and passenge...
