On the other hand, simultaneously via air drying plant 112 → air purge groove 113 → air filter 9 → boiler check valve 8, deliver to each control with air bellow 4 and store in these air bellows from the pressurized air of air compressor 3 output.
Be stored in each control and use the air of air bellow 4 then to pass through each boiler check valve 15 → each open and close valve 14, be sent to each adjustment valve 5 and transmit valve 6 with each.
By rotating each knob N respectively, adjust to desirable air pressure delivering to each air of adjusting valve 5, and deliver to each then and transmit valve 6.
Here, each effect of transmitting valve 6 is, fill/arrange each control with the air between air bellow 4 and each tire 2 according to adjusting from each that valve 5 desirable air are pressed and pressing, thereby make each tire 2 keep desired air pressure automatically from the air of each tire 2.
That is to say, press when pressing when adjust valve 5 desirable air from each from the air of each tire 2, then use the air of air bellow 4 just via each boiler check valve 15 → each open and close valve 14 → each transmits valve 6 → each swivel joint 7 → each tyre valve 19 → each tire 2, gives each inflation of tire from each control.
And when the air pressure of each tire 2 was charged to desired set quota, each control inflated just no longer for each tire 2 with air bellow 4.
On the contrary, press when pressing from the air of each tire 2 when adjust valve 5 desirable air from each, then from the air of each tire 2 just via each tyre valve 19 → each swivel joint 7 → each transmits valve 6, exhaust in ambient atmosphere.
In case the air of each tire 2 presses to desirable air when pressing, and just ends exhaust automatically, and the air of keeping this hope is pressed.
In addition, when the air of each tire 2 is pressed because the variation of ambient temperature, or when pressing or pressing greater than desirable air less than desirable air, each transmits valve 6 and just can work as said process, keeps each tire 2 automatically and remains desirable air and press.
Certainly, by rotating the knob N that each adjusts valve 5, just can be individually individually and adjust the air pressure of each tire 2 arbitrarily continuously.
At this moment, each tire 2 is adjusted respectively on request one by one, big, the excellent in efficiency of degree of freedom, and, operate also very simply, only need the relevant open and close valve 14 of unlatching and the tire that will adjust 2 just passable.
Even the operation of the tire air pressure-controlled of preceding note is also harmless in brake equipment 111 uses.
Why? this is because the air bellow that is used to brake 115 is independent respectively settings with the air bellow 4 that is used for tire air pressure-controlled.
Moreover, because being used for control air air bellow 4 of pressing and the air bellow 115 that is used to brake also is being connected to each other by boiler check valve 10, so,, also can utilize the air of air bellow 4 to make brake equipment 111 brakes when the air drops of the air bellow 115 that is used to brake is not enough to glancing impact.
Swivel joint 7 forms air communication chamber 22 and grease reception room 23 by four seal rings 24 at least, and the grease reception room is being filled grease for 23 li, therefore, the air of air communication chamber 22 is by seal ring 24 and complete leak free while of grease, seal ring 24 is also given good lubricating by grease, thereby makes whole swivel joint 7 maintain extraordinary sealing effectiveness.
Though be noted that at last in the above-described embodiment, establish tire 2 and have four, also can not be subjected to the restriction of this numeral, for example, also can be 2-3 or more than 5.
Equally, in the above-described embodiment, also establish control and have four with air bellow 4, this also can be not limited thereto, and for example also can be 1-3 or more than 5.
Similarly, among the embodiment in front, have four seal rings 24 though establish swivel joint 7, can certainly be not limited, such as also being even number more than 6.
In addition, among the embodiment in front, supply with road 27 though swivel joint 7 opens and closes grease by stopper 30, this also can be not limited, such as, also can supply with connection grease feedway (not having drawing to represent) on the road at grease.
