Description
One. technical field
Tire of the present invention belongs to the airtight technical field of tire from pressure regulation method and tire from regulator, and what be specifically related to is tire can be inflated the automatic voltage regulation of losing heart under high-speed operation method and automatic pressure regulating device.
Two. background technology
Airtyred every in-use performance is all closely related with the height size of inner pressure of tire, too high or too low interior pressure not only seriously affects main economy such as loading of tire ability, cushion characteristic, wearing and tearing, oil consumption and technical index, also greatly affect the maneuvering performance and the safety in utilization of tire, data shows according to the relevent statistics, and what got into an accident on the express highway is 40% all undesirable relevant with the air pressure of tire.During present domestic tire used, all serious overload all must increase substantially down and could realize at inner pressure of tire.How guaranteeing that tire depresses use in being fit to, is the problem that traffic and safety are very paid close attention to, and also is to press for the problem of researching and solving technically.
The way that solves loss of tyre pressure and insufficient pressure at present mainly contains two kinds: a kind of is to lack pressure early warning way, promptly presses in the monitoring tyres in real time, gives the alarm when lacking pressure or superpressure.Another kind is the pressure release way of guaranteeing, and relies on the upholder of pre-installing in the tire to guarantee the tire safety segment distance that travels behind loss of tyre pressure.Two kinds of ways respectively have advantage that deficiency is also all arranged.Application number is: 90209538.2 Chinese patent discloses a kind of " the adjustable ultra micro barostat of tire tire tube valve formula ", this tire barostat does not have the gas storage source, tire pressure variable range ultra micro is little, as this patent oneself explanation: this tire barostat can only " be applicable to bicycle, motor bike, three-wheel vehicle etc. " small-sized tire, and also range of regulation is that ultra micro is little; In addition, its adjusting connecting rod stretches in the tire to be regulated, and the inner tube of a tyre of stabbing small-sized tire easily is its another weak point.Also see the another one Chinese patent: " bicycle high pressure automatic inflation pump " (patent No.: ZL92244677.6), it is not full automatic, also only be suitable for using on the Bicycle dilly, it can only be inflated in bicycle running, but must stop to turn-off down or opening inflation at bicycle.This with on the cross-country car of desert, carry high-pressure gas cylinder and so on, tire is used as the tire make-up gas after the pressure release in the desert fully, but the example that can only after parking, put on the air, both effects are just in time opposite, but from finding out both weak points separately here just.Tire of the present invention from pressure regulation method and tire from regulator, be the method for energy automatic voltage regulation under the tire high-speed operation and the device of automatic voltage regulation, it has one preferably to be running dynamical equilibrium shape, or approximately dynamical equilibrium ground is connected with tire or together gas storage source is installed, and is maximum characteristics.
Three. summary of the invention
