Above, to regulate and the architectural feature of vehicle of explosion protection have been introduced having installed tire pressure, below, according to the different conditions in vehicle travel process and mutually change, specifically introducing the method for described vehicle adjusting knurl air pressure.Suppose that standard pressure when vehicle is in low speed light condition is P1, pressure during high speed light loading is P2, pressure during low-speed heave-load is P3, pressure during high-speed overload is P4, then when setting the standard value range of tire pressure, P1 < P2 < P3 < P4 should be made.It should be noted that, the concrete number range of P1, P2, P3, P4 specifically should set according to dissimilar vehicle and dissimilar tire.In addition, P1 < P2 < P3 < P4 is over all, and emphasize that P1 < P2 < P3 < P4 is also the convenience in order to state, and when the standard pressure value scope of actual set tire, between P1 and P2, between P2 and P3 and also may there is the overlap of certain limit between P3 and P4.
1, the detection (supposing that now vehicle is light condition) during vehicle launch
Open car key, connect the battery isolator control K7 of vehicle.
(1) if the air pressure now in tire 5 is within the scope of standard value P1, so the first pressure unit B1-7 will not be subjected to displacement because of the equilibrium of pressure at two ends, left and right, and the first pressure sensor B1 corresponding with the first pressure unit B1-7 then can keep Z in the position shown in the figure 1; Load measuring sensor K5, car speed sensor K6 are in the state of disconnection, first two-position relay K switch 1 is in the state that upper/lower positions key is communicated with, upper position keys disconnects, second relay switch K2, the 3rd relay switch K3, the 4th relay switch K4 are also in the state that upper/lower positions key is communicated with, upper position keys disconnects, this just means that the storage battery 12 on the first electromagnet A1 and car body is connected, and the second electromagnet A2, the 3rd electromagnet A3, the 4th electromagnet A4 are all in the state disconnected with storage battery 12.
After first electromagnet A1 is communicated with storage battery 12, under the driving of electric power, move on to position Y from the position X shown in Fig. 1.Now, because the air pressure in tire 5 is within the scope of standard value P1, therefore the first pressure sensor B1 still remains on position Z, and the second electromagnet A2 be not communicated with storage battery 12, the 3rd electromagnet A3, the 4th electromagnet A4 then remain on position X because not being energized.Meanwhile, because the pressure P 1 in tire is lower than the second pressure unit B2-5, 3rd pressure unit B3-7, standard pressure (the second pressure unit B2-5 that 4th pressure unit B4-5 sets, 3rd pressure unit B3-7, the standard pressure of the 4th pressure unit B4-5 respectively according to underloading at a high speed, heavy-duty low-speed, heavy duty standard setting at a high speed), therefore the second pressure sensor B2, 3rd pressure sensor B3, 4th pressure sensor B4 is towards the second electromagnet A2, 3rd electromagnet A3, one end of 4th electromagnet A4 remains on position Y, that is position X can not be moved to by position Y.Therefore, first electromagnet A1, the second electromagnet A2, the 3rd electromagnet A3, the 4th electromagnet A4 all do not contact with the first pressure sensor B1, the second pressure sensor B2, the 3rd pressure sensor B3, the 4th pressure sensor B4, that is the conducting ring on described each electromagnet does not all contact with contact of exitting with the contact of inflating on the hold-down arm of described each pressure sensor.In this case, motor 11 does not rotate because not being energized, and inflation pump 10 does not work, and relay 9 cuts out, and tire 5 is in the state of the pressure P 1 that maintains the standard.
(2) if the air pressure in tire 5 is lower than standard value P1, then the pressure of the first pressure unit B1-7 left end (one end be connected with the hold-down arm of the first pressure sensor) is greater than the pressure of right-hand member (one end be connected with the unit penstock of tracheae 8), the first pressure unit B1-7 is caused to move to right, drive two on the hold-down arm of the first pressure sensor B1 to inflate contact B1-2 and B1-6 and move on to position Y from position Z, thus contact with two conducting ring A1-2 with A1-1 on the first electromagnet A1 respectively, motor 11 is caused to be communicated with storage battery 12, motor 11 rotates under the driving of electric power, inflation pump 10 is driven to inflate to tire 5, tire 5 air pressure progressively improves.When the air pressure in tire 5 reaches standard value P1, first pressure unit B1-7 moves to left, drive two on the hold-down arm of the first pressure sensor B1 to inflate contact B1-2 and B1-6 to move to right, thus disconnect with two conducting ring A1-2 and A1-1 on the first electromagnet A1, now, motor 11 loses electric power and stops operating, and inflation pump 10 does not work, relay 9 cuts out, and tire 5 is in the state of the pressure P 1 that maintains the standard.It should be noted that, the pressure of the first pressure unit B1-7 left end equals P1 originally, but, after the first pressure unit B1-7 moves to right, the pressure of its left end can become and be less than P1 (such as, after stretching as the elastomeric element in the diaphragm pressure switch of pressure unit, the pressure of its left end is caused to diminish), therefore, when the air pressure in tire 5 reaches standard value P1, first pressure unit B1-7 can move to left, until when the pressure at its two ends, left and right is P1, just remain on balance position.In like manner, after the second pressure unit B2-5, the 3rd pressure unit B3-7, the 4th pressure unit B4-5 move right, the pressure of its left end can diminish.In addition, the "left", "right" in this specification sheets, Figure 1 shows that standard.
(3) if the air pressure in tire 5 is higher than standard value P1, then the pressure of the right-hand member of the first pressure unit B1-7 is greater than the pressure of its left end, under the effect of tire pressure, first pressure unit is moved to the left, on the hold-down arm on the first pressure sensor two contact B1-1 and B1-3 that exit are driven to move to left, and with the conducting ring A1-1 of two on the first electromagnet, A1-2 contacts, thus relay switch 9 is communicated with storage battery 12, relay switch 9 is opened after being energized, exit to tire 5, when the air pressure of tire 5 drops to standard pressure P1, first pressure unit B1-7 moves to right, on hold-down arm on first pressure sensor two contact B1-1 and B1-3 that exit are moved to right, with the conducting ring A1-1 of two on the first electromagnet, A1-2 disconnects, close after relay 9 power-off, stop venting, tire 5 is in the state of the pressure P 1 that maintains the standard.It should be noted that, the pressure of the first pressure unit B1-7 left end equals P1 originally, but, after the first pressure unit B1-7 moves to left, the pressure of its left end can become and be greater than P1 (such as, after the elastomeric element of diaphragm pressure switch is compressed, the pressure of its left end is caused to become large), therefore, when the air pressure of tire 5 drops to standard pressure P1, first pressure unit B1-7 can move right, until when the pressure at its two ends, left and right is P1, just remain on balance position.In like manner, after the second pressure unit B2-5, the 3rd pressure unit B3-7, the 4th pressure unit B4-5 move to left, the pressure of its left end can become large.
2, in vehicle traveling, the tire pressure of different conditions regulates
(1) low speed underloading → high speed light loading → low speed underloading
After vehicle launch, after first electromagnet A1 is energized, position Y is shifted to the right to from the position X shown in Fig. 1, now, if the pressure of tire 5 equals standard value P1, then the first pressure sensor B1 is at position Z, the second electromagnet A2, the 3rd electromagnet A3, the 4th electromagnet A4 all at position X, the second pressure sensor B2, the 3rd pressure sensor B3, the 4th pressure sensor B4 towards one end of the second electromagnet A2, the 3rd electromagnet A3, the 4th electromagnet A4 at position Y.Because not being communicated with storage battery, motor 11 does not turn, and relay 9 cuts out, and tire 5 is in the state of the pressure P 1 that maintains the standard.
When vehicle under steam, when forwarding high speed to by low speed, car speed sensor K6 connects automatically, and (car speed sensor K6 connects when which kind of speed vehicle reach, can determine according to the concrete specification of tire and vehicle, such as, general bridge car is 110 kilometers/hour, general bogie is 90 kilometers/hour).After car speed sensor K6 connects, the first relay switch K1 is converted into the state that upper/lower positions key disconnects, upper position keyed jointing is logical, and the second electromagnet A2 is communicated with storage battery 12, and the second electromagnet A2 obtains electric moving to right.Meanwhile, because the upper/lower positions key of the first relay switch K1 disconnects, make the first electromagnet A1 power-off, get back to position X along the axial of semiaxis 3 from position Y.Now, due to the standard pressure P1 when air pressure in tire 5 is low speed light condition, low relative to underloading standard pressure P2 at a high speed, therefore the pressure of the coupling end of the unit penstock of tracheae 8 and the second pressure unit B2-5 is less than the pressure of the other end of the second pressure unit B2-5, that is second the pressure of pressure unit B2-5 right-hand member be less than the pressure of its left end, this pressure unit is caused to move to right, thus cause two on the hold-down arm of the second pressure sensor B2 to inflate contact B2-1 and B2-8 moving to left (as shown in Figure 3, the moving direction of contact of inflating is contrary with the moving direction of pressure unit), and contact with conducting ring A2-2 with A2-1 of two on the second electromagnet respectively, thus motor 11 is communicated with storage battery 12, rotate after motor 11 is energized, inflation pump 10 is driven to inflate to tire 5, as standard pressure value P2 under the high speed light loading state that the air pressure in tire 5 reaches set, second pressure unit B2-5 moves to right, force two on the hold-down arm of the second pressure sensor B2 to inflate contact B2-1 and B2-8 to move to right, disconnect with conducting ring A2-2 and A2-1 of two on the second electromagnet respectively, cause motor 11 dead electricity, inflation pump 10 stops inflating, tire 5 is in pressure P 2 state that maintains the standard, vehicle maintains and runs at high speed.
When car speed is from when transferring low speed at a high speed, car speed sensor K6 disconnects automatically, first relay switch K1 is in the upper/lower positions key shown in Fig. 5 and is communicated with, the state that upper position keys disconnects, the second electromagnet A2 power-off is caused to move to left, first electromagnet A1 energising moves to right, because now tire pressure P2 is higher than the air pressure P1 of low speed underloading, therefore the pressure of the first pressure unit right-hand member (one end be connected with the unit penstock of tracheae 8) is greater than the pressure of its left end (one end be connected with the hold-down arm of the first pressure sensor), two of first pressure sensor B1 contact B1-1 and B1-3 that exit are moved to left, contact with two conducting ring A1-2 with A1-1 of the first electromagnet, thus open after causing relay switch 9 to be energized, exit to tire 5, when the pressure in tire 5 is reduced to standard pressure P1, two venting contact B1-1 and B1-3 on the hold-down arm of the first pressure sensor B1 move to right, on respectively with the first electromagnet, two conducting ring A1-2 and A1-1 disconnect, relay switch 9 dead electricity is closed, stop venting.Tire 5 is in the state of the pressure P 1 that maintains the standard.
(2) low speed underloading → low-speed heave-load → high-speed overload → low-speed heave-load → low speed underloading
When vehicle transforms low-speed heave-load by low speed underloading, load measuring sensor K5 connects automatically, second relay switch K2 is energized and is in the state that upper/lower positions key disconnects, upper position keys is communicated with, first electromagnet A1 power-off is moved to left, 3rd electromagnet A3 energising moves to right, meanwhile, the connection of load measuring sensor K5 also can cause that the upper position keyed jointing of the 4th relay switch K4 is logical, upper/lower positions key disconnects.Now, pressure due to the 3rd pressure unit B3-7 right-hand member (one end be connected with the unit penstock of tracheae 8) is equivalent to the pressure P 1 under low speed light condition, this pressure is less than the pressure P 3 needed for tire reality under low-speed heave-load state, the 3rd pressure unit is caused to move to right, make two on the hold-down arm of the 3rd pressure sensor B3 to inflate contact B3-3 and B3-8 to move to left, position Y is moved on to from the position Z Fig. 1, thus connect respectively with two conducting ring A3-2 and A3-1 on the 3rd electromagnet, motor 11 is energized, drives inflation pump 10 to inflate to tire 5.When the pressure in tire 5 reaches the standard pressure P3 required by low-speed heave-load, 3rd pressure unit B3-7 moves to left, make two on the hold-down arm of the 3rd pressure sensor B3 to inflate contact B3-3 and B3-8 to move to right, thus disconnect with two conducting ring A3-2 and A3-1 on the 3rd electromagnet, motor 11 power-off stall, inflation pump 10 quits work.Now, automobile is in low speed fully laden, and tire is in the state of the pressure P 3 that maintains the standard.
