Abstract

The invention discloses a device for simulating the fast deflation of the tire burst in an automobile, which is characterized in that the device comprises a wheel rim (1), a flange sealing device (5),a relief valve device (2), and a plurality of air ducts (4); a plurality of deflation holes are formed in the outer edge of the wheel rim, and each deflation hole is connected with one air hole of the flange sealing device through one air duct; a sealing space is formed among the wheel rim, the air duct, and the flange sealing device; the relief valve device is fixedly connected with the flange sealing device, and the relief valve device is opened to deflate the air in the tire through the plurality of air ducts and the relief valve device, so that the fast deflation is achieved, and the tireburst phenomenon of the automobile is simulated. According to the device for simulating the fast deflation of the tire burst in an automobile, the operability is high, and the simulation experimentscan be repeated; and the deflation holes are formed in the outer edge of the wheel rim, so that neither the wheel tire nor the wheel rim structure are damaged.

Description

technical field [0001] The invention relates to a device for simulating a tire blowout and rapidly deflation for automobile safety. Background technique [0002] Relevant statistics show that 10% of traffic accidents on expressways are caused by tire failures, and tire blowouts account for more than 70% of the total accidents caused by tire failures. Therefore, it is urgent to study the safety of automobile tire blowouts. . [0003] The standard of the Ministry of Communications "Safety Technical Conditions for Passenger Cars in Operation" (JT1094-2016) clearly stipulates that the front wheels of commercial passenger cars with a vehicle length greater than 9m must be equipped with a tire burst emergency safety device. [0004] The national standard "Technical Conditions for Motor Vehicle Operation Safety" (GB7258-2017) clearly stipulates that special school buses, passenger cars with a length of more than 9m without a passenger standing area, and steering wheels of dangerou...
