Description
Technical field
The utility model is related to automotive fields, specifically a kind of rotary more particularly, to automobile tire inflation/deflation technology
Pneumatic valve and its gas control unit.
Background technology
Automobile tire air-charging and air-discharging system is the system that a set of automobile can adjust tire pressure at any time in stagnation of movement.Its master
Acting on is：When automobile is by the soft terrains such as desert, Coastal beach, marsh, slob and ice and snow road, pass through the system
Tire pressure can be rapidly reduced, the contact area of tire is increased；On the one hand reduce tire sinkage and soil resistance；It is another
Aspect increases since tire is embedded in decorative pattern number in soil, increases the propulsive force of soil, tractive force is dramatically increased, carry
The passability of high automobile.
When the height of transporting cars is by limitations such as bridge opening, culvert, mother aircraft hatch doors, in a certain range, if
Tire pressure is reduced, so that automobile total height is suitably reduced, just can pass through.
When road environment temperature is higher and automobile long-distance continuously drives, since tire fever makes intrauterine pressure increase,
It may cause tyre break, it, can be to avoid dangerous situation if automobile tire in the process of moving can be given to deflate in real time
Generation
Military offroad vehicle is transporting weaponry, vehicular weapons system, communication commanding system and when the wounded of battlefield, if
Tire pressure can be adjusted in real time according to different condition of road surface and slow down impact and vibration, mobility, the safety of military supplies can be enhanced
Property and survival ability.

Under the influence of air pressure, it is moved toward front chamber 10；I.e. push rod block 22 is equipped with isolation front chamber 10 and seals one end of room 8 towards ante-chamber
Room 10 is moved, and front chamber 10 and sealing room 8 communicate immediately, and air-flow is rapidly filled with front chamber 10；Further, gas flow is vented
The first air flue being connected between mouthfuls 4 and front chamber 10, then gas be discharged from exhaust outlet 4, be transported in tire.
When deflation finishes, peripheral hardware feeder Quick air-discharge, the immediately air pressure of the second air flue 13 and third air flue 14 is distinguished
It is zero, meanwhile, the air pressure in rear chamber 11 is zero, and the residual gas of front chamber 10 moves push rod block 22 toward rear chamber 11, directly
To returning to home position.
When bleeding a tire, peripheral hardware feeder starts deflation flow, gives pulse gas, by push rod block 22 toward front chamber 10
It is mobile；Immediately along the path backtracking of air inlet, i.e. the interior gas of tire inputs gas from exhaust outlet 4, enters the first gas
Road, and enter front chamber 10.Due at this point, rear chamber 11 there is also pressure, so front chamber 10 and sealing room 8 are constantly in
It communicates；With that is, gas flows to sealing room 8 from front chamber 10, during sealing room 8 quickly fills with gas and the second air flue 13 is sent to be discharged to
Gas channel 2 in axis block 3；The gas of rear chamber 11 flows to the second air flue 13 by third channel 14 and is transported to axis simultaneously
The gas channel 2 of block 3, finally, gas are output to extraneous air feed equipment from the gas channel 2 of axis block 3.Realize putting for tire
Gas.
When deflation finishes, peripheral hardware feeder Quick air-discharge, the immediately air pressure of the second air flue 13 and third air flue 14 is distinguished
It is zero, meanwhile, the air pressure in rear chamber 11 is zero, and the residual gas of front chamber 10 moves push rod block 22 toward rear chamber 11, directly
To returning to home position.
During inflation/deflation, in order to and so that driver is known the air pressure of tire in time and realize that the automatic of tire is filled
Gas and deflation, air flue are equipped with the sensing device that can incude 10 air pressure of front chamber towards extraneous opening.Sensing device 21 is distinguished
It is communicated to connect with data processing module and message processing module.
Although the utility model is illustrated by specific embodiment, it will be appreciated by those skilled in the art that, not
In the case of being detached from the scope of the utility model, various transformation and equivalent substitute can also be carried out to the utility model.In addition, being directed to
Particular condition or application can do various modifications, without departing from the scope of the utility model to the utility model.Therefore, this reality
It is not limited to disclosed specific embodiment with novel, and should include the whole fallen within the scope of the utility model claims
Embodiment.
