Anti-overturn safety protection device for tire burst

Technical Field

The utility model relates to the technical field of automobiles, specificly relate to a safety arrangement is prevented turning over by flat child.

Background

In the process of high-speed running of an automobile, because of certain reasons, such as that a tire is punctured by a sharp object, the tire pressure does not meet the regulations or the tire is seriously worn, the tire can not bear high pressure and high temperature during high-speed running, the tire burst occurs, no tire burst prevention device is installed on the automobile at present, and the conventional treatment method when the tire burst occurs is as follows: the driver's experience is relied on to deal with the situation, the accelerator is loosened, the brake is not stepped on, the steering wheel is well held, the automobile is maintained to run straight, and the automobile is slowly decelerated. Many drivers are often in a busy and messy state when encountering the emergency, so that the automobile is out of control and overturns, and particularly the truck carrying goods is more dangerous when being punctured, thereby bringing hidden troubles to driving safety.

At present, if a tyre of a common automobile used at present is burst during running, the tyre loses the supporting force instantly, so that the gravity center of the automobile is changed, a light person can cause the automobile to turn over, and the automobile seriously has life danger. If the tire is replaced by the explosion-proof tire, most people cannot accept the tire because of high cost and high price. Therefore, a tire burst anti-overturn safety protection device with lower cost is needed.
