Automobile tire blowout test device

Abstract

The invention discloses an automobile tire burst test device. The test device comprises a parameter detection sensor, a wire, an arc-shaped integrated conversion connector, an air inlet pipe with quick connectors at two ends, an air collection cavity, a slip ring, a slip ring support, a slip ring stator, a rotary connector, an air pipe with a quick connector and an air release valve. According tothe device, a driver can directly operate and control opening and closing of the valve, gas in a tire is rapidly released under the action of air pressure difference, so that the tire burst phenomenonof the automobile tire is simulated, and required parameters are obtained through the parameter detection sensor. The tire burst test device is suitable for tire burst tests of different vehicle types at different speeds and under different road conditions; during a real vehicle dynamic test, the test device can be used for simulating tire burst working conditions at different deflation times ina vehicle driving process, and data such as vehicle lateral acceleration, yaw velocity, vehicle body roll angle and the like during the tire burst are obtained by utilizing the sensor, so that the reason of yawing or instability of the vehicle during tire burst is conveniently analyzed, and the active safety control of the vehicle is favorably improved.

Description

technical field [0001] The invention relates to an automobile tire blowout test device, which belongs to the field of automobile safety. Background technique [0002] With the rapid development of road and bridge construction technology, the grades of roads in various places are generally improved, and cars are often running at high speeds. The high-speed driving of cars not only easily leads to the occurrence of tire blowouts, but also the consequences of high-speed tire blowouts will be very serious. According to the traffic department data, major traffic accidents caused by tire blowouts account for more than 70% of the total traffic accidents, and usually cause more serious consequences. Therefore, it is a difficult problem that enterprises and researchers must solve to study the phenomenon of tire blowout of high-speed vehicles and its impact on vehicle handling stability after tire blowout and active intervention. Therefore, inventing a test device for simulating a pu...
