Detailed description of the invention
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As shown in Figure 1, many chamber anti-breaking tyres originally with High Performance check valve comprise carcass 100 and the some chambers be arranged in carcass 100, chamber comprises inflating cells 200 and the multiple gas storage chambers 210 adjacent with inflating cells 200, the first separate layer 600 is provided with between inflating cells 200 and each gas storage chamber 210, first separate layer 600 is provided with and makes the gas in inflating cells 200 enter check valve 300 in gas storage chamber 210, the second separate layer 610 is provided with between adjacent two gas storage chambers 210, check valve 300 comprises valve body, piston, pressure cap and the sealing layer between valve body and pressure cap.
Preferably, the quantity of above-mentioned chamber is 4, but the quantity of chamber is not limited to 4, buffer chamber 220 is also offered in tire, be oppositely arranged between inflating cells 200 and buffer chamber 220, and filling channel 500 is provided with between inflating cells 200 and buffer chamber 220, filling channel 500 is arranged on the second separate layer, two gas storage chambers 210 are arranged at the both sides of inflating cells 200 and buffer chamber 220 respectively, gas flows in buffer chamber 220 at first, and flow in inflating cells 200 by filling channel 500, owing to being equipped with guide valve between inflating cells 200 and two gas storage chambers 210, under normal condition, guide valve is in normally off, thus gas constantly gathers in inflating cells 200, air pressure in inflating cells 200 raises gradually, when the air pressure in inflating cells 200 is more than or equal to the conducting air pressure of guide valve, thus gas backs down guide valve flows in two gas storage chambers 210, inflating cells 200 makes gas enter in two gas storage chambers 210 respectively by check valve 400, thus ensure that the air pressure equal and opposite in direction between two gas storage chambers 210, improve vehicle stationarity in the process of moving, add the stationarity that vehicle travels.
Further, two gas storage chambers 210 are as the main supporting part of tire, thus the volume of two gas storage chambers 210 is all greater than the volume of buffer chamber 220 or inflating cells 200, ensure that the weight capacity of tire, two gas storage chambers 210 are symmetricly set in tire both sides, make the weight uniformity of vehicle be dispensed to tire both sides, decrease the load-bearing in the middle part of tire, reduce the probability of tyre break, ensure that vehicle is in the process travelled, the stability of tire also improves the stationarity that vehicle travels simultaneously.
Buffer chamber 220 is also provided with charge valve 300, communicate between buffer chamber 220 with charge valve 300, gas flows in buffer chamber 220 by charge valve 300, the filtration of charge valve 300 avoids impurity and enters in buffer chamber 220 along with air-flow, rub with the inwall of tire, long friction can cause tyre wall thinning, and tire is easily burst in the process of moving.
The setting of above-mentioned buffer chamber 220, the gas of importing is slowly gathered in charge valve 300, when the gas in charge valve 300 reaches a certain amount of, gas slowly flows into inflating cells 200 along filling channel 500, charge valve 300 is equivalent to a buffer gear, to avoid between inflating cells 200 and two gas storage chambers 210 after conducting, the air-flow entering buffer chamber 220 in charge valve 300 is unstable, thus make the amount of gas between inflow two gas storage chambers 210 unequal, cause the air pressure in two gas storage chambers 210 unequal, reduce the stationarity that vehicle travels, tire is even caused to burst.
Further, separate layer arrange tire portion to be four, to ensure that the independence between each chamber, improve the leak tightness of tire, avoid the gas leakage of vehicle chamber or burst under stressed larger state.
In the process of the motion of tire, when there is air chamber gas leakage or explosion in inflating cells 200 or buffer chamber 220, setting due to check valve 400 makes air-flow unidirectionally can only flow to two gas storage chambers 210 from inflating cells 200, thus the normal work of two gas storage chamber 210 air chambers can not be affected, ensure tire normal rotation, avoided tyre break and cause the generation traffic accident unexpected out of control of vehicle; When two gas storage chambers 210 there is air chamber gas leakage or explosion in one of them, also gas leakage or the explosion of air chamber can be there is in inflating cells 200, but another gas storage chamber 210 in two gas storage chambers 210 still can normally work, vehicle can not be out of control suddenly because of the explosion of tire, vehicle can slowly stop by driver, has ensured the safety that vehicle travels.
