Description
Technical Field
The invention relates to the field of automobile tires, in particular to a tire burst emergency device installed in small and medium-sized automobile tires. .
Background
Current wheeled vehicles, including automobiles, are primarily pneumatic tires, and blowout of the pneumatic tires is technically unavoidable, and therefore, blowout is a potential risk that cannot be avoided with all wheeled vehicles. The statistical data shows that 70% of the accidents on the domestic expressway are caused by tire burst, most drivers have no driving experience after tire burst, and once the tire burst happens, the drivers are likely to make errors such as sudden braking and the like, so that the vehicles are out of control, and the probability of casualties and property loss caused by accidents is very high. The main reason for the harm after the automobile tire burst is the transverse slip and the longitudinal deviation, which are reflected in that:
1. longitudinal offset: the tire wall of the inflated tire is the main part for supporting the weight of the vehicle, and the tire burst usually causes the instantaneous collapse of the tire wall, so that the tire loses the supporting force instantaneously, the center of gravity of the vehicle is changed immediately, the vehicle imbalance is caused, and the vehicle is out of control;
2. and (3) transverse slipping: the reason is that the transverse acting force generated by rolling the tire by the wheel after tire burst causes the wheel to slide, the adhesion force between the wheel and the ground is very small when the automobile runs at high speed, the capability of resisting the transverse sliding is very limited, the automobile is out of control, the influence caused by the wheel sliding after the tire burst of the automobile is related to the position of the wheel, even if the wheel sliding is generated after the tire burst of the front wheel, the direction is only out of control, the wheel sliding is generated after the tire burst of the rear wheel, the consequence is that the head is turned over, the tail is thrown or the automobile rolls over, the automobile is completely out of control, and the consequence.
In view of the above circumstances, the automobile industry in the world has been engaged in the research and development of tire burst prevention and rescue technologies, and the main technical solutions are:
1. electronic guarding technique
(1) Pressure monitoring system (TPMS for short): the core of the TPMS technology is to monitor the air pressure and temperature of the tire in real time, so as to give an early warning and a reminding, reduce and eliminate the danger which may occur when the tire bursts, reduce the probability of the tire burst, and belong to the prior prevention technology.
(2) Flat tire monitoring and safety control system (BMBS): the core of the BMBS technology is real-time monitoring of tire air pressure and rapid driving braking, tire conditions are known in advance in the driving process, and high pressure and high temperature of tires are alarmed to prevent tire burst accidents; the automobile can brake in time after tyre burst, the adhesive force between the wheels and the ground is increased, the braking force generated by the normal wheels on the side corresponding to the tyre burst wheels is larger than or close to the sum of the rolling resistance and the braking force of the tyre burst wheels, and the wheels can not slide under the support of ABS. The essence of the method is the combined application of the TPMS technology and the ABS technology, and the main application manufacturer is Jili corporation.
2. Tyre explosion-proof technology
(1) PAX (self-supporting) tire system: the PAX tire system consists of four parts, namely an outer tire, a special rim, an internal support ring and a pressure detector, and the technical core is to reduce the height of the tire, enhance the support rigidity of the tire side, support the tire by the rim and the internal support ring after the tire is deflated, reduce the height reduction of the wheel after the tire is blown out and provide basic running performance at a lower speed. The PAX tire system is introduced by michelin corporation, but the shock absorbing performance of the tire is greatly reduced, but the comfort performance of the automobile is reduced, the manufacturing cost of the tire is greatly increased, and the rim with a special design makes the popularization more difficult, and the michelin corporation has stopped further research and development of the PAX tire system at present.
(2) RSC (run flat) tire technology: the core of the technology is that the height of the tire is reduced, the thickened rubber side wall enables the side wall to lose air pressure and also can support the weight of a vehicle, serious deformation cannot be caused, meanwhile, a fixing ring is installed in the tire and supports the tire from the inner side, so that the tire cannot be crushed, and meanwhile, the tire can be prevented from falling off from a tire gasket. The primary application manufacturer is BMW.
(3) The non-pneumatic tire: the inflation-free tire is a tire which realizes the damping and buffering performance without the help of air pressure, the core of the technology is to realize the supporting and buffering performance by utilizing the material and the structure of the tire, one is a rubber solid tire which is suitable for large vehicles with low moving speed and higher loading requirements; the other type is an open structure tire, utilizes open structure and tubular staggered three-dimensional shock absorption, and is mainly used on military special vehicles. The non-inflatable tire can only run at low speed, has large tire noise and high oil consumption, and is not acceptable in the civil market.
(4) The multi-air-chamber tire technology comprises the following steps: the core of the technology is that a plurality of air chambers are arranged in the tire, when one air chamber bursts, the rest air chambers can still provide basic supporting rigidity to ensure basic traveling performance, but the situation that one air chamber bursts to cause the rest air chambers to simultaneously burst cannot be avoided, and the technology is not put into commercial application.
(5) Coaxial tire pressure intercommunication technology: the core of the technology is that a left tire air chamber and a right tire air chamber which are coaxial are communicated through a complex mechanism, so that the direction deviation caused by rolling resistance after the tire burst of the tire on one side of the coaxial is avoided, but the technology is still in an experimental stage at present, and only American military carries out tests on military automobiles.
However, these designs suffer from the following problems and disadvantages:
1. the emergency disaster after the tire burst can not be rescued: such as TPMS technology.
2. The technology has the defects that: such as multi-air chamber tire technology, multi-air chamber tire technology and coaxial tire pressure intercommunication technology.
3. The use of special devices or tires is required: such as a PAX (self-supporting) tire system.
4. The price is expensive: such as RSC (run flat) tire technology, PAX (self-supporting) tire systems, flat tire monitoring and safety control systems. .
