The fan-shaped inner tubes are communicated to the annular inner tubes in a unified mode, so that tire inflation operation is only needed to be carried out from one position during inflation, otherwise, each fan-shaped inner tube is in trouble of inflation operation, air pressure in different fan-shaped inner tubes cannot be unified, tire pressure instability is easily caused, and the annular inner tubes serve as inflation interfaces to ensure that all the fan-shaped inner tubes are inflated with gas with consistent pressure. The ventilation valve through which the space in the annular inner tube and the space in the fan-shaped inner tube are communicated can be a one-way valve or a two-way valve, and the one-way valve is well understood, namely, gas can only flow from the annular inner tube to the fan-shaped inner tube, so that after one fan-shaped inner tube is broken, the gas leakage of the other fan-shaped inner tubes cannot be caused through the annular inner tube; the vent valve can also be bi-directional air-passing, but should ensure that after a certain fan-shaped inner tube is broken, the vent valve can be timely disconnected, and the following description of the specific implementation structure shows that the vent valve has the following advantages: in the subsequent normal use of the tire, the air leakage of different fan-shaped inner tubes is inconsistent, and the two-way valve keeps the air in all the fan-shaped inner tubes communicated all the time, namely the pressure is uniformly reduced, namely: when the tire is normally used, the air in all the fan-shaped inner tubes is still integrated, but when one of the fan-shaped inner tubes is broken, the fan-shaped inner tube can be isolated in time due to the existence of the special vent valve.
Furthermore, a shaft hole is formed in the center of the hub, a transmission groove is formed in the end face of one side of the central portion of the hub, the transmission groove extends in the radial direction and is distributed in the circumferential direction, and one end of the transmission groove is connected to the shaft hole; a transmission assembly is arranged in the shaft hole and comprises a hub bearing and a rotating block, the hub bearing is arranged in the shaft hole, one end of an inner ring of the hub bearing is hinged with the rotating block, the hinge axis of the hub bearing and the rotating block is vertical to the axis of the hub, and when the rotating block rotates to the length direction and is vertical to the axis of the hub, the rotating block is embedded into the transmission groove; the multi-air-bag explosion-proof tire further comprises a pressure plate, wherein the pressure plate is in a cap shape, and the pressure plate is in threaded connection with the wheel hub and compresses the rotating block in the transmission groove.
In the prior art, the automobile wheel is generally connected with an automobile wheel shaft through a hub bearing, and the hub bearing is then connected with a shock absorption system and a chassis of an automobile. The invention also uses the hub bearing to connect with the automobile wheel shaft, only the structure of the hub bearing is increased, the inner ring of the hub bearing is still in transmission connection with the wheel shaft by using keys or splines, the inner ring of the hub bearing is hinged with a plurality of turning blocks at the tail part, the turning blocks are used as the inner ring of the hub bearing and the transmission part of the wheel hub, the turning blocks also have the responsibility of axial positioning and locking, the turning blocks are hinged with the inner ring of the hub bearing, a hinge shaft is vertical to the axis of the wheel hub, so that the rotation of the inner ring of the hub bearing and the rotation of the turning blocks around the hinge are mutually independent, the turning blocks are pressed by a pressing cover after being rotatably embedded into a transmission groove around the hinge position, the rotation of the inner ring of the hub bearing around the axis of the wheel hub is transmitted to the turning blocks to enable the turning blocks to also rotate around the axis of the wheel hub, the turning blocks drive the transmission groove to rotate to establish, is the axial fixation of the turning block. When the tire is disassembled, the pressure plate only needs to be rotated down, the rotating block is shifted to be horizontal, the hub and the hub bearing can be disassembled very quickly, the inner tire and the outer tire communicated with the hub are repaired or replaced after the hub is disassembled, and the hub bearing is inserted to implement installation operation after the maintenance and the replacement are completed. The outer edge of the pressure plate can be made into regular polygons such as hexagon and octagon, so that the pressure plate can be conveniently rotated by the outside, just like a hexagonal nut.
Further, the vent valve comprises a first valve seat and a second valve seat, the valve ball is arranged between the first valve seat and the second valve seat, the first elastic body and the second elastic body are fixed on two sides of the valve ball respectively, one end, far away from the valve ball, of the first elastic body abuts against the stepped surface of the first air hole, one end, far away from the valve ball, of the second elastic body abuts against the stepped surface of the second air hole, and the diameter of the valve ball is larger than the diameter of a passage hole at the position, close to the valve ball, of the first air hole and the second air hole respectively.
As mentioned above, when the annular inner tube and the sector inner tube are connected only by using the one-way air passing valve, when the automobile is in the later stage of driving, the pressure reduction caused by air leakage in different sector tires is different, so that the pressure reduction curve of each sector tire is not uniform, the pressure of the inner tube of the tire is unstable, the supporting force provided by the automobile is slightly changed in the period of one circle of rolling of the tire, but the change can cause slight vibration of the automobile during driving, which may cause potential safety hazard, but in order to ensure the characteristics of multiple air bags, the sector inner tube and the rest of the sector inner tubes must be timely isolated when the sector inner tube explodes; therefore, how to maintain the characteristics of multiple air bags and unify all the fan-shaped inner tubes into a whole in the normal running process is a problem of performance optimization.
The invention arranges the idea of a bidirectional air passing valve, and when in inflation and normal use, all the fan-shaped inner tubes are communicated with the annular inner tube, and can pass through the vent valve with low resistance.
The valve ball between the first valve seat and the second valve seat is elastically supported in the middle by the elastic bodies on the two sides, when the pressure difference on the two sides of the vent valve is lower, taking the pressure on one side of the annular inner tube as an example, although the pressure difference on the two sides can blow the valve ball to one side of the fan-shaped inner tube, the pressure difference can not enable the first elastic body to be compressed to the bottom and the valve ball to block the first vent hole, so that the air in the annular inner tube can flow into the fan-shaped inner tube until the pressures on the two sides are the same, and the inflation process of the tire is also realized; after the inflation process is finished, in the subsequent driving process, the tire pressure of one sector inner tube is higher, the tire pressures of the other sector inner tubes are lower, and the pressure difference can not press the valve ball to seal the second vent hole, so that the gas in the sector inner tube with higher tire pressure can reversely flow back to the annular inner tube and then flow to the other sector inner tubes until the pressures of all the inner tubes are the same, namely the inner tube pressure balancing process;
when a certain sector tire is broken, the pressure difference of two sides of the vent valve connected with the sector tire is changed sharply, the pressure of the annular inner tube is on one side, the atmospheric pressure is on the other side, the valve ball is blown to the first valve seat by the pressure difference and the first vent hole is blocked, the gas of the annular inner tube is prevented from being discharged outwards, and the process is the isolation process of the broken sector tire.
Preferably, the first valve seat and the second valve seat are provided with sealing rings on the nesting contact surfaces. The first valve seat and the second valve seat can only communicate at the first vent hole and the second vent hole, and the nesting contact surfaces of the first valve seat and the second valve seat can be reliably sealed, so that the sealing ring is arranged, and if the first valve seat and the second valve seat are made into elastic members such as rubber members, the separately arranged sealing ring can be omitted.
Furthermore, the end face of one side of the pressure plate, which is far away from the hub, is provided with a bicycle logo. The vehicle logo can play a role in decoration, so that the tire is more attractive.
Compared with the prior art, the invention has the beneficial effects that: according to the invention, the plurality of fan-shaped inner tubes are arranged in the outer tire, and after one of the fan-shaped inner tubes is broken, the surrounding fan-shaped tires can fill corresponding spaces in time, so that the tires are not integrally burst, and thus the short-term running can be continued; the fan-shaped inner tube is connected with the annular inner tube, the inflation process of the tire is uniformly carried out, and the vent valve which flows in two directions is arranged at the connection part, so that the tire pressures of all the inner tubes of the tire which normally runs are kept the same, and the uneven stress of the tire in the rolling period is prevented; the double-elastic-body elastic supporting structure of the valve ball in the vent valve can timely block the fan-shaped tire vent channel after a certain fan-shaped tire is broken, so that the broken tire is ensured not to influence other inner tubes.

As mentioned above, when the air vent valve 9 is used to connect the annular inner tube 4 and the sector inner tube 2 only by using the one-way air vent valve, when the automobile is in the later driving stage, the pressure reduction caused by air leakage in different sector tires is different, so that the pressure reduction curve of each sector tire is not uniform, and the pressure of the inner tube of the tire is unstable, during the period of one circle of rolling of the tire, the provided supporting force slightly changes, but the change can cause slight vibration of the automobile during driving, which may cause potential safety hazard, but also in order to ensure the characteristic of multiple air bags, the sector inner tube 2 must be timely isolated from the rest sector inner tubes 2 when one sector inner tube 2 explodes; therefore, how to maintain the characteristics of multiple air bags and unify all the fan-shaped inner tubes 2 into a whole in the normal running process is a problem of performance optimization.

The inner tube is inflated at the air nozzle 41, the annular inner tube 4 respectively sends gas to each sector-shaped inner tube 2 and keeps the pressure of each sector-shaped inner tube 2 consistent, and the air nozzle 41 is closed after the inflation is finished. In the running process of an automobile, after a certain sector-shaped inner tube 2 is punctured, the pressure difference between two sides of the connected vent valve 9 is too large, the first elastic body 94 and the valve ball 95 of the vent valve 9 are extruded to seal the first vent hole 911, so that the gas in the annular inner tube 4 cannot be discharged outwards, and meanwhile, the inner tube beside the punctured sector-shaped inner tube 2 is expanded to fill the empty space, so that the tire can continuously run for a short time, and a driver can maintain the tire as early as possible.
