What is a Tire Blowout Safety Device?
2 Answers
Tire Blowout Safety Device is a brand-new automotive passive safety product that effectively ensures the safety of passengers and the vehicle in the event of a tire blowout. It represents the fourth generation of automotive passive safety protection systems, following seat belts, ABS, and airbags. Functions of the Blowout Safety Device: It promptly releases the drastically increased motion resistance of the wheel, thereby maintaining control over the vehicle's direction and preventing loss of steering control due to a sudden drop in tire pressure on one side. The device is easy and reliable to install without altering the original vehicle structure; it is sturdy and lightweight, preserving the original wheel balance; and it is resistant to corrosion, cold, and heat, without affecting fuel consumption. Principle of the Blowout Safety Device: Through calculations and mathematical simulations, it has been determined that within 0.3 seconds of a tire blowout at a speed of 100 km/h, the friction, lateral forces, and other forces generated between the blown-out tire and the ground increase to more than 33 times their original levels. It is precisely these amplified forces that cause the vehicle to lose directional control, bounce up and down, sway side to side, and potentially roll over, leading to unavoidable accidents. When a vehicle equipped with this device experiences a tire blowout, the safety device, acting on the inner surface of the tire, synchronizes its rotation with the tire by utilizing the aforementioned 33-fold increase in friction and lateral forces. Meanwhile, the inner ring, under the rotational force of the outer ring, decelerates relative to the wheel rim, allowing the rim to maintain the original rotational speed of the wheel.
I've worked in the automotive industry for many years. The tire anti-burst safety device is essentially a run-flat design that allows you to continue driving for a short distance when a tire bursts or leaks, unlike conventional tires that immediately go flat. Its principle is quite ingenious—the tire sidewalls are specially reinforced with stiffer rubber materials, enabling them to support the vehicle's weight even without air pressure. For example, if you suddenly experience a tire leak on the road, this device lets you drive to the nearest repair shop, typically around 50 kilometers, avoiding the danger of changing tires on the roadside. Compared to traditional tires, it's safer and more reliable, reducing the risk of losing control during a blowout. However, it does have some drawbacks: the ride might be less comfortable with more noticeable bumps, and it's generally more expensive. Installation depends on the vehicle model—some cars come equipped with a tire pressure monitoring system from the factory, which is quite user-friendly. Overall, it's a practical innovation that makes driving safer, especially useful for highway travel.
