Small and medium-sized automobile tire burst emergency device

Abstract

The invention relates to a small and medium-sized automobile tire burst emergency device that is an inner tire which is arranged in a small and medium-sized automobile tire and is made of a material with light weight, high strength and certain buffering capacity, can be a tire with a honeycomb-shaped, honeycomb-shaped, multi-dimensional and other hollow structures, is tightly combined with a rim by virtue of the elasticity of the tire, and keeps a certain distance with the small and medium-sized automobile tire. According to the tire burst emergency device, harm caused by tire burst of the automobile tire is reduced in a simple and reliable mode, the safety guarantee level of drivers and passengers is improved, and impact on automobile structures and parts is reduced.

Description

technical field [0001] The invention relates to the field of automobile tires, in particular to a tire burst emergency device installed inside small and medium-sized automobile tires. . Background technique [0002] Current wheeled vehicles including automobiles mainly adopt pneumatic tires, and the bursting of pneumatic tires is technically unavoidable. Therefore, bursting tires is an unavoidable potential danger for all wheeled vehicles. Relevant statistics show that 70% of accidental traffic accidents on domestic highways are caused by blown tires, and most drivers have no driving experience after a blown tire. Once a blown tire occurs, they are likely to make mistakes such as sudden braking, which will The possibility of loss of vehicle control, accidents, casualties, and property damage is extremely high. The main cause of the hazard after the car blows out is the lateral slip and longitudinal offset, which are reflected in: [0003] 1. Longitudinal offset: The infla...

AI Technical Summary

Problems solved by technology

[0003] 1. Longitudinal offset: The inflated tire sidewall is the main part supporting the weight of the vehicle. A puncture usually causes the tire sidewall to collapse instantaneously, causing the tire to lose its supporting force instantly, resulting in an immediate change in the center of gravity of the vehicle, causing the vehicle to become unbalanced. causing the car to lose control;

[0004] 2. Lateral slip: The cause is that the tire is crushed by the tire after the tire is blown out and the lateral force is generated to cause the wheel to slip. Since the adhesion between the wheel and the ground is very small when the car is running at high speed, the ability to resist lateral slip is very limited, resulting in The car is out of control, and the impact caused by the slippage of the wheel after the car blows out is related to the position of the wheel. Even if the front wheel slips after the blowout, it only shows that the direction is out of control, and the slippage of the rear wheel blows out, and the consequence is turning around and throwing The tail end or rollover, the car is completely out of control, the consequences are more serious than the front tire blowout

Non-pneumatic tires can only run at low speeds, with high tire noise and high fuel consumption, which is unacceptable for the civilian market

[0013] (4) Multi-chamber tire technology: The core of the technology is that there are multiple air chambers in the tire. When one of the air chambers bursts, the rest of the air chambers can still provide basic support stiffness to ensure the basic exercise performance, but it is impossible to avoid one The explosion of the gas chamber causes the other gas chambers to burst simultaneously, and has not yet been put into commercial application

[0016] 1. It is impossible to provide rescue for sudden disasters after a tire blowout: such as TPMS technology

[0017] 2. Technical defects: such as multi-chamber tire technology, multi-chamber tire technology, coaxial tire air pressure communication technology

[0019] 4. Expensive: such as RSC (run flat) tire technology, PAX (self-supporting) tire system, tire burst monitoring and safety control system
