When the air pressure in tire 5 meets standard, deflation contact on the support arm of four pressure sensors and inflate contact and do not contacted with the conducting ring of four blocks of electromagnet；When the air pressure in tire 5 is higher than standard value, two conducting rings at least one block electromagnet are moved towards and contacted with two deflation contacts corresponding to it, relay switch 9 is caused to be connected with battery 12, relay switch 9 is opened after being powered, so as to be deflated to tire 5；When the air pressure in tire 5 is less than standard value, at least one block electromagnet On two conducting rings and two corresponding to it inflate contact and move towards and contact, cause motor 11 to be connected with battery 12, inflated so as to start inflating pump 10 to tire 5.

More than, to being mounted with that tire pressure regulation and the architectural feature of the vehicle of explosion-protection equipment are introduced, below, different conditions and its mutually conversion in vehicle travel process specifically introduce the method that the vehicle adjusts tire pressure.Assuming that normal pressure when vehicle is in low speed light condition is Pl, pressure during high speed light loading is P2, and pressure during low-speed heave-load is P3, and pressure during high-speed overload is P4, then when setting the standard value range of tire pressure, should make P1< P2< P3< P4.It should be noted that Pl, P2, P3, P4 concrete numerical value scope should specifically be set according to different types of vehicle and different types of tire.In addition, P1< P2< P3<P4 is over all, and to emphasize P1< P2< P3<P4 and in the standard pressure value scope of actual set tire, also likely to be present a range of overlapping also for the convenience of statement between P1 and P2, between P2 and P3 and between P3 and P4.

1st, detection during vehicle launch（Assuming that now vehicle is light condition）

Car key is opened, the battery main switch K7 of vehicle is connected.

(1) if now the air pressure in tire 5 is in the range of standard value P1, so first pressure unit B 1-7 will be because the pressure balance of left and right ends be without being subjected to displacement, and the first pressure sensor B1 corresponding with first pressure unit B 1-7 can then keep Ζ in the position shown in the figure 1;Load measuring sensor Κ 5, vehicle speed sensor Κ 6 are in the state disconnected, first two-position relay switch K1 is in the state that lower position keys are connected, upper position keys disconnect, the state that second relay switch Κ 2, the 3rd relay switch Κ 3, the 4th relay switch Κ 4 are also at lower position keys connection, upper position keys disconnect, this means that the first electromagnet A1 is connected with the battery 12 on car body, and the second electromagnet Α 2, the 3rd electromagnet A3, the 4th electromagnet Α 4 are in the state disconnected with battery 12.

After first electromagnet A1 is connected with battery 12, under the driving of electric power, position bifurcation is moved on to from the position X shown in Fig. 1.Now, because the air pressure in tire 5 is in the range of standard value P1, therefore first pressure sensor B1 remains at position Ζ, and the second electromagnet Α 2, the 3rd electromagnet A3, the 4th electromagnet Α 4 that are not connected with battery 12 are then maintained at position X because being not powered on.At the same time, because the pressure P1 in tire is less than the normal pressure that second pressure unit Β 2-5, the 3rd pressure unit Β 3-7, the 4th pressure unit Β 4-5 are set（Second pressure unit Β 2-5, the 3rd pressure unit Β 3-7, the 4th pressure unit Β 4-5 normal pressure respectively according to underloading high speed, heavy-duty low-speed, heavily loaded high speed standard setting）Therefore second pressure sensor Β 2, the 3rd pressure sensor Β 3, the 4th pressure sensor Β 4 towards the second electromagnet Α 2, the 3rd electromagnet A3, the 4th electromagnet Α 4 one end are maintained at position Υ, that is, position X can not be moved to by position Υ.Therefore, first electromagnet Al, the second electromagnet Α 2, the 3rd electromagnet A3, the 4th electromagnet Α 4 are not contacted with first pressure sensor Bl, second pressure sensor Β 2, the 3rd pressure sensor Β 3, the 4th pressure sensor Β 4, that is, the conducting ring on each electromagnet with the support arm of each pressure sensor inflate contact and deflation contact is not contacted.In this case, motor 11 is because being not powered on without rotating, and inflating pump 10 is not worked, and relay 9 is closed, and tire 5 is in the state for keeping normal pressure P1.

(2) if the air pressure in tire 5 is less than standard value Pl, first pressure unit B 1-7 left ends（The one end being connected with the support arm of first pressure sensor）Pressure be more than right-hand member（The one end being connected with the unit penstock of tracheae 8）Pressure, cause first pressure Unit B l-7 is moved to right, drive two on first pressure sensor B1 support arm to inflate contact B1-2 and B1-6 and move on to position Y from position Z, so as to be contacted respectively with two conducting rings A1-2 and A1-1 on the first electromagnet A1, motor 11 is caused to be connected with battery 12, motor 11 is rotated by electric power, inflating pump 10 is driven to be inflated to tire 5, the air pressure of tire 5 is stepped up.When the air pressure in tire 5 reaches standard value P1, first pressure unit B 1-7 is moved to left, drive two on first pressure sensor B1 support arm to inflate contact B1-2 and B1-6 to move to right, so as to be disconnected with two conducting rings A1-2 and A1-1 on the first electromagnet A1, now, motor 11 loses electric power and stopped operating, and inflating pump 10 does not work, relay 9 is closed, and tire 5 is in the state for keeping normal pressure P1.It should be noted that, the pressure of first pressure unit B 1-7 left ends is equal to Pl originally, but, after first pressure unit B 1-7 is moved to right, the pressure of its left end can become less than P1 (for example, after being stretched 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 B 1-7 can be moved to left, and when the pressure of its left and right ends is P1, just be maintained at equilbrium position.Similarly, after second pressure unit Β 2-5, the 3rd pressure unit Β 3-7, the 4th pressure unit Β 4-5 move right, the pressure of its left end can diminish.In addition, " left side ", " right side " in this specification, to be defined shown in Fig. 1.

(3) if the air pressure in tire 5 is higher than standard value Pl, then the pressure of first pressure unit B 1-7 right-hand member is more than the pressure of its left end, in the presence of tire pressure, first pressure unit is moved to the left, two deflation contact B1-1 and B1-3 on the support arm on first pressure sensor are driven to move to left, and with two conducting ring Al-1 on the first electromagnet, A1-2 is contacted, so that relay switch 9 is connected with battery 12, relay switch 9 is opened after being powered, deflated to tire 5, when the air pressure of tire 5 drops to standard pressure P1, first pressure unit B 1-7 is moved to right, so that two deflation contact B1-1 and B1-3 on support arm on first pressure sensor are moved to right, with two conducting ring Al-1 on the first electromagnet, A1-2 disconnects, relay 9 is closed after powering off, stop deflating, tire 5 is in the state for keeping normal pressure P1.It should be noted that the pressure of first pressure unit B 1-7 left ends is equal to Pl originally, still, after first pressure unit B 1-7 is moved to left, the pressure of its left end can go above P1 (for example, after the elastomeric element of diaphragm pressure switch is compressed, causing the pressure of its left end to become big）, therefore, when the air pressure of tire 5 drops to standard pressure P1, first pressure unit B 1-7 can move right, and when the pressure of its left and right ends is P1, just be maintained at equilbrium position.Similarly, after second pressure unit Β 2-5, the 3rd pressure unit Β 3-7, the 4th pressure unit Β 4-5 are moved to left, the pressure of its left end can become big.

2nd, the tire pressure of different conditions is adjusted in vehicle traveling

(1) low speed underloading → high speed light loading → low speed underloading

After vehicle launch, after first electromagnet A1 is powered, position Υ is shifted to the right to from the position X shown in Fig. 1, now, if the pressure of tire 5 is equal to standard value Pl, then first pressure sensor B1 is in position Ζ, second electromagnet Α 2, the 3rd electromagnet A3, the 4th electromagnet Α 4 in position X, second pressure sensor Β 2, the 3rd pressure sensor Β 3, the 4th pressure sensor Β 4 towards the second electromagnet Α 2, the 3rd electromagnet A3, the 4th electromagnet Α 4 one end in position Υ.Because not connected with battery, motor 11 does not turn, and relay 9 is closed, and tire 5 is in the state for keeping normal pressure P1.

When vehicle under steam, when going to high speed by low speed, the turn on automatically of vehicle speed sensor Κ 6（Vehicle speed sensor Κ 6 reaches in vehicle Connect, can be determined according to the The concrete specification of tire and vehicle during which kind of speed, for example, general bridge car is 110 kilometers/hour, general bogie is 90 kilometers/hour）.After vehicle speed sensor K6 is connected, the first relay switch K1 is converted into lower position keys disconnection, the bonded logical state in upper position so that the second electromagnet A2 is connected with battery 12, and the second electromagnet A2 obtains electric move to right.At the same time, because the first relay switch K1 lower position keys disconnect so that the first electromagnet A1 is powered off, axially position X is returned to from position Y along semiaxis 3.Now, standard pressure Pl when due to the air pressure in tire 5 being low speed light condition, standard pressure P2 relative to underloading high speed is low, therefore the unit penstock of tracheae 8 and the pressure of second pressure unit B 2-5 connection end are less than the pressure of the second pressure unit B 2-5 other end, that is, the pressure of second pressure unit B 2-5 right-hand members is less than the pressure of its left end, cause the pressure unit to move to right, moved to left so as to cause two on second pressure sensor B2 support arm to inflate contact B2-1 and B2-8（From the figure 3, it may be seen that inflate contact moving direction it is opposite with the moving direction of pressure unit）, and contacted respectively with two conducting rings A2-2 and A2-1 on the second electromagnet, so that motor 11 is connected with battery 12, motor 11 is rotated after being powered, driving inflating pump 10 is inflated to tire 5, when the air pressure in tire 5 reaches the standard pressure value P2 under set high speed light loading state, second pressure unit B 2-5 is moved to right, force two on second pressure sensor B2 support arm to inflate contact B2-1 and B2-8 to move to right, disconnected respectively with two conducting rings A2-2 and A2-1 on the second electromagnet, cause the dead electricity of motor 11, inflating pump 10 stops inflating, tire 5, which is in, keeps normal pressure P2 states, vehicle maintains to run at high speed.

When car speed switchs to low speed from high speed, vehicle speed sensor K6 disconnects automatically, the lower position keys that first relay switch K1 is in shown in Fig. 5 are connected, the state that upper position keys disconnect, the second electromagnet A2 power-off is caused to move to left, first electromagnet A1 is powered and moved to right, because now tire pressure P2 is higher than the air pressure P1 of low speed underloading, therefore first pressure unit right-hand member（The one end being connected with the unit penstock of tracheae 8）Pressure be more than its left end（The one end being connected with the support arm of first pressure sensor）Pressure, so that first pressure sensor B1 two deflation contact B1-1 and B1-3 are moved to left, contacted with two conducting rings A1-2 and A1-1 of the first electromagnet, so as to cause relay switch 9 to be opened after being powered, deflated to tire 5, when the pressure in tire 5 is reduced to standard pressure P1, two deflation contact B1-1 and B1-3 on first pressure sensor B1 support arm are moved to right, disconnected respectively with two conducting rings A1-2 and A1-1 on the first electromagnet, the dead electricity of relay switch 9 is closed, and stops deflating.Tire 5 is in the state for keeping normal pressure P1.

(2) low speed underloading → low-speed heave-load → high-speed overload → low-speed heave-load → low speed underloading

When vehicle converts low-speed heave-load by low speed underloading, load measuring sensor K5 turn on automatically, second relay switch K2 is powered and is in lower position keys disconnection, the state that upper position keys are connected, move to left the first electromagnet A1 power-off, 3rd electromagnet A3 is powered and moved to right, at the same time, load measuring sensor K5 connection also results in the 4th relay switch K4 bonded logical, the lower position keys disconnection in upper position.Now, due to the 3rd pressure unit B3-7 right-hand members（The one end being connected with the unit penstock of tracheae 8）Pressure equivalent to the pressure Pl under low speed light condition, the pressure is less than the actually required pressure P3 of tire under low-speed heave-load state, the 3rd pressure unit is caused to move to right, so that two on the 3rd pressure sensor B3 support arm are inflated contact B3-3 and B3-8 and moved to left, position Y is moved on to from the position Z in Fig. 1, so as to be respectively turned on two conducting ring Α 3-2 and A3-1 on the 3rd electromagnet, motor 11 is powered, drive inflating pump 10 to be inflated to tire 5.When the pressure in tire 5 reaches the standard pressure Ρ 3 required by low-speed heave-load, the 3rd pressure unit Β 3-7 are moved to left, So that two on the 3rd pressure sensor B3 support arm are inflated contact B3-3 and B3-8 and moved to right, so as to be disconnected with two conducting rings A3-2 and A3-1 on the 3rd electromagnet, the power-off stalling of motor 11, inflating pump 10 is stopped.Now, automobile is in low speed full load condition, and tire is in the state for keeping normal pressure P3.

When vehicle enters high-speed overload state by low-speed heave-load state, load measuring sensor K5 and vehicle speed sensor K6 are in connected state, first two-position relay switch Kl, the 3rd two-position relay switch Κ 3 switch Κ 4 with the 4th two-position relay and are in the state that lower position keys are disconnected, upper position keys are connected, battery 12 is caused to be connected with the 4th electromagnet Α 4, while disconnecting the connection between the electromagnet A3 of battery 12 and the 3rd.4th electromagnet Α 4 is shifted to the right to position Υ after being powered from position X, and moves left to position X from position Υ after the 3rd electromagnet A3 power-off.At the same time, in the case of vehicle high-speed heavy duty, air pressure Ρs 3 of the normal pressure Ρ 4 compared with tire under the conditions of low-speed heave-load needed for tire 5 is high, that is, the 4th pressure unit Β 4-5 and the 4th pressure sensor Β 4 support arm connection end pressure be less than tire 5 needed for normal pressure Ρ 4, so as to cause two on the 4th pressure sensor Β 4 support arm to inflate contact Β 4-6 and Β 4-8 position Υ is moved on to from position Ζ, respectively with two conducting ring A4-2 of the 4th electromagnet, A4-1 is connected, cause motor 11 to be powered to rotate, driving inflating pump 10 is inflated to tire 5.When the air pressure in tire 5 reaches required standard pressure Ρ 4,4th pressure unit Β 4-5 are moved to left, cause two on the 4th pressure sensor Β 4 support arm to inflate contact Β 4-6 and Β 4-8 to move to right, disconnected with two conducting rings A4-2, A4-1 on the 4th electromagnet, the power-off stalling of motor 11, inflating pump 10 is stopped.Now, automobile is in high-speed overload state, and tire 5 is in the state for keeping normal pressure Ρ 4.

If vehicle is changed into low-speed heave-load from high-speed overload, then vehicle speed sensor Κ 6 disconnects, 3rd relay switch Κ 3 is disconnected by lower position keys, the state of upper position keys connection is changed into lower position keys connection, the state that upper position keys disconnect, so that the 4th electromagnet Α 4, which is powered off and moved to left along the axial direction of semiaxis 3 from position Υ, returns to position X, 3rd electromagnet A3 is axially shifted to the right to position Υ along semiaxis 3 after being powered from position X, now, because tire pressure is Ρ 4, higher than the normal pressure Ρ 3 required by low-speed heave-load, so that the 3rd pressure unit Β 3-7 move left to position Υ, two conducting ring Α 3-2s and A3-1 of two deflation contact Β 3-4 and the Β 3-9 on the 3rd pressure sensor Β 3 support arm respectively with the 3rd electromagnet A3 are caused to connect, so that relay switch 9, which is powered, opens switch deflation, as the standard pressure Ρ 3 required by the pressure in tire 5 drops to heavy-duty low-speed state, 3rd pressure unit Β 3-7 are shifted to the right to position Ζ, two conducting ring Α 3-2s and A3-1 of two deflation contact Β 3-4 and the Β 3-9 on the 3rd pressure sensor Β 3 support arm respectively with the 3rd electromagnet A3 are caused to disconnect.Now, vehicle is in low-speed heave-load state, and tire 5 is in the state for keeping normal pressure Ρ 3.

If vehicle is further changed into underloading low speed from heavy-duty low-speed, then load measuring sensor Κ 5 disconnects, 4th relay switch Κ 4 is changed into the state that upper position keys are disconnected, lower position keys are connected, second relay switch Κ 2 is changed into the state that upper position keys are disconnected, lower position keys are connected, position X is returned to so that being moved to the left after the 3rd electromagnet A3 power-off along the axial direction of semiaxis 3 from position Υ, the first electromagnet A1 axially moves right to position Υ along semiaxis 3 after being powered from position X.Now, because the standard pressure Ρ 3 required by heavy-duty low-speed state is higher than the air pressure Pl required by underloading lower-speed state, therefore first pressure unit B 1-7 is moved to the left, so that two deflation contact B1-1 and B1-3 on first pressure sensor B1 support arm are in position Υ, connected respectively with the conducting ring A1-2 on the first electromagnet A1 with A1-3, so that after relay switch 9 is powered, opening switch and being deflated to tire 5, when the air pressure in tire 5 drops to low speed During normal pressure P1 required by underloading, first pressure unit B 1-7 is moved to right, two deflation contact Bl-1, B1-3 on first pressure sensor B1 support arm are driven to be shifted to the right to position Z from position Y, so as to be disconnected with conducting ring Al-2, A1-1 on the first electromagnet A1, the power-off closing of relay switch 9 is caused, stops deflating.Now vehicle is in low speed light condition, and tire 5 is in the state for keeping normal pressure P1.
