Abstract
The invention belongs to the technical field of automobile safety traffic, and relates to an automobile tire pressure adjusting technique which can be used for adjusting instable automobile tire pressure and effectively suppressing tire explosion accident. The anti-explosion automobile tire is mainly characterized in that a secondary tire air storage structure is added on the basis of a conventional automobile tire; when the running tire pressure is higher, the surplus air is discharged into the secondary tire through a one-way valve structure between the main tire and the secondary tire; and if the air pressure in the secondary tire achieves a certain upper limit value, the surplus air is discharged out of a tire system in a mode that the pressure of a one-way valve spring on the secondary tire self is overcome. When the running tire pressure is lower than the lowest safety traffic pressure, the air is supplemented and aerated into the main tire from the secondary tire through the one-way valve structure between the main tire and the secondary tire, so that the situation that the running tire works within a safety traffic tire pressure range is effectively ensured.
Description
Technical field
The invention belongs to motor tire field, especially a kind of motor tire that adopts major-minor tire structure.
Background technology
For the explosion-proof self-checking device of tire, external relatively maturation is TPMS system at present.TPMS technology is mainly divided into indirect type TPMS and direct-type TPMS.Indirect type TPMS is mainly that the wheel speed sensors by automobile ABS carrys out the rotating speed difference between comparative tire, thereby reaches the object of monitoring tire pressure.But it cannot to two above tires, situation and the situation of speed over 100 kilometers/hour of deficency judge simultaneously.And direct-type monitoring tire pressure technology is mainly to utilize sensing transmitter directly to monitor tire pressure, and the mode by transmission over radio sends on reception telltale the pressure signal spying out.This system is mainly comprised of three parts: sensing transmitter, receptor and telltale.This three's the object that is used in conjunction with to reach dangerous air pressure automatic alarm.Because direct-type TPMS is better than indirect type TPMS in performance, so direct-type TPMS technology becomes dominant technology.
The domestic research for TPMS technology is still improved and the market starting stage in product, and the supporting market of industrialization starts not yet on a large scale, and one of the main reasons is that this systematic study cost is very high.No matter be in research and development field or in market segment so domestic, have to be developed.
Direct-type TPMS system strides forward to the third generation at present, its principal feature is to be based upon on the basis of second generation tire pressure monitoring system, consider the shortcoming of the short easy temperature influence of battery life, take passive monitoring, original lithium cell energy supply equipment is changed into and relies on internal mechanism for whole sensor provides the energy, have so undoubtedly considerable realistic meaning and economic implications.
But from subjective, direct-type TPMS device only limits to reflect in real time the pressure condition of tire.When tire pressure mal, just this message is passed to chaufeur, remind chaufeur to take to change accordingly tire inflation measure, do not carry out the real-time adjusting of tire pressure.
When pressure of tire is too high, not only cause blowing out while running at high speed, and normal driving is also interfered at ordinary times.For example, tire noise change is in the process of moving large; Tire can make vehicle body jumping frequency rate excessive in some fluctuating sections, and comfort declines; Too high tire pressure give turn to bring slim and graceful in, the tyre side while making to turn to also reduces to earth-grasping force, thereby causes too early understeer and produce threat.In addition, the most important thing is that too high tyre pressure can make the ground contact area of tire diminish, on the road surface of low adhesive ability, cause car brakeing effect to reduce.
And when pressure of tire is too low, not only the noise of tire still exists, and greatly reduce on driving performance.When chaufeur is being beaten fast bearing circle and turned, it is heavy that the weight of bearing circle becomes, and the speed of response of headstock latens slow, equally there will be understeer when curved.In addition, the most important thing is that oil consumption improves greatly.Therefore, must the tire pressure of tire be limited in Applicable scope actv., improve service life and the safety performance of tire, effectively prevent the generation of the accident of blowing out.
