Description
Technical Field
The invention relates to the technical field of tires, in particular to a pneumatic and non-pneumatic dual-purpose limit tire component structure.
Background
Tires are an important component of wheeled vehicles, whose main functions are to support loads, transmit driving forces, braking forces, steering forces to the ground, and to cushion and dampen the traction and throughput capabilities of the wheeled vehicle, as well as braking, ride comfort, steering stability, economy, reliability, and even environmental performance, with direct impact.
Along with the improvement of the national economic level and the expansion of the activity radius, the demands of people for tires under different situations are continuously improved, the contradiction between the complexity and the replacement inconvenience of the current tires and the demand of people for one-tire multi-purpose simple and quick is more and more prominent, and the national development of one-tire multi-purpose limit tires has become a necessary trend. Through the development of the years, an irreversible situation of a multipurpose simple and quick type limit tire is basically formed, but the current trend still faces a serious challenge, and the development of the multipurpose simple and quick type limit tire becomes a technical bottleneck of tire enterprises in all countries worldwide.
The implementation of the conventional different-situation tyre requirements is mostly realized by depending on frequent replacement of various special tyres, such as: in order to prevent the tire from air leakage and tire burst, people develop a run-flat tire with a support adhesive attached to a tire side part, but the problem is that the running distance is very limited in the air-deficient state, the vehicle can only be supported to run at a lower speed, the tire is not reusable after running in the air-deficient state, and the problem of structural design is that the support force in the middle of the tire is insufficient; people have also researched and developed solid explosion-proof tires, but the problems of excessive raw materials, poor pavement adaptability, poor comfort level, excessive oil consumption, large unsprung mass of vehicles, poor dynamic performance of vehicles and the like are more remarkable, and the solid explosion-proof tires are not practical to be widely applied to civil vehicles.
People need to enter the extremely severe road sections such as the broken stone puncture road for long distance running after the expressway long distance running, and the vehicle can meet the requirement of the expressway long distance running when being provided with the common radial tire at the moment, but the extremely severe road sections such as the broken stone puncture road can need frequent replacement and repair of damaged tires, waste tires are wasted, the tire is inconvenient, and too many spare tires are unlikely to be prepared on the vehicle.
If a run-flat tire is arranged on a vehicle, the vehicle cannot run for a long distance after the run-flat tire leaks, and the vehicle cannot be qualified; if the vehicle is provided with the solid explosion-proof tire, the comfort level of the long-distance running section of the expressway is extremely poor and the oil consumption is extremely high, so that the requirement of long-distance running cannot be met; in the above cases, frequent tire replacement is not always avoided.
For another example: in desert, people usually reduce the tire air pressure to increase the tire grounding area, so as to reduce the sand subsidence of the tire and increase the grip force, but after the air pressure is reduced, the deflection of the sidewall can be increased, so that the sidewall generates more heat, and in addition, the temperature of the sand polar end of the desert is extremely high, the tire damage rate is extremely high, and frequent tire replacement is unavoidable.
The contradiction between the complexity and inconvenience of the current tires and the requirement of people on multiple purposes, simplicity and rapidness of one tire is more and more prominent, and the problem that the conventional tires cannot meet the requirement that people adjust the tire pressure for different terrains for continuous use exists.
