Embodiment
[0038] Embodiment: a kind of method for tire air pressure driving simulation puncture, it is characterized in that: comprise:
[0039] S1: Align the reserved hole on the device base 1 with the fixing hole on the side of the tire, and then connect the two with bolts;
[0040] S2: Connect the air supply pipe of tire stabbing cylinder 2 and linkage cylinder 7 to the valve of the tire. At this time, the electromagnetic valve is normally closed, and the corresponding tire stabbing cylinder 2 is in a state of decompression and no power. At this time, the piston rod retracts. Tire puncture cylinder 2;
[0041] S3: When the connection of S2 is completed, the air supply pipe of the linkage cylinder 7 communicates with the air inside the tire, and is driven by the air pressure inside the tire. The tire connecting rod 6 is penetrated and inserted at the same time, so that the active connecting rod 3 and the tire-punctured connecting rod 6 are penetrated by it, and the linkage swing of t...

The invention discloses a tire air pressure driven tire burst simulating device and method. The device is characterized in that the device comprises a device base, a tire puncturing air cylinder, a driving connecting rod, a tire puncturing connecting rod with one end provided with a tire puncturing bayonet, a reset coil spring, and a hinge shaft fixed with the driving connecting rod, wherein the driving connecting rod is connected with the tire puncturing connecting rod; one end of the reset coil spring is fixed to the hinge shaft, and the other end of the reset coil spring abuts against a coil spring stop pin fixedly arranged on the tire puncturing connecting rod; the driving connecting rod is provided with a linkage air cylinder, and linkage swing of the driving connecting rod and the tire puncturing connecting rod is achieved through air pressure driving insertion fit. The device is simple in structure and ingenious in design; the air cylinder driving unit is arranged, tire internal pressure is creatively used as power for air supply, the convenience and applicability of the device are improved, safety tests, tire burst simulation exercise, driving training and the like of manual driving and automatic driving automobiles are facilitated, and the abruptness and randomness of actual tire burst can be well restored through remote control, and the whole process is high in safety coefficient and can be repeatedly used.
Description
technical field [0001] The invention relates to the technical field of automobile safety tests, in particular to a simulated tire blowout device driven by tire air pressure, and also relates to a simulated tire blowout method driven by tire air pressure. Background technique [0002] With the popularization of automobiles in life, the traffic accident rate is also increasing year by year. Among them, the survey shows that more than 70% of traffic accidents on expressways are caused by blown tires, and once the speed of the car exceeds 100km / h, if driving If the driver fails to take the correct operation in this extremely short period of time, it may directly lead to a rollover. Currently, it is shown that the accident fatality rate of a high-speed rollover is close to 100%. It can be seen that the driver should take correct corresponding actions in time at the moment of a car tire blowout. is very important. Therefore, in the operation and driving training and learning, it ...
