Principle of work is:
14 pairs of height of wagon of height adjusting valve same as the prior art carry out automatic guidance.When the weight in somewhere in the compartment increases, the compartment moves down because of the air bag smaller volume of air bellow, and drivening rod mechanism moves down the spool of height adjusting valve 14, thereby the chargine line of compressed air line and air bellow control unit is connected, to air bag 10 inflation of respective air spring, until rising on the compartment till getting back to operational height.In like manner, when the weight in somewhere in the compartment reduces, rise on the compartment, and drivening rod mechanism, the spool of height adjusting valve is moved up, thereby the chargine line of air bellow control unit is communicated with atmosphere, and the air bag 10 outside exhausts of respective air spring descend and till getting back to operational height until the compartment.
The function of one-way throttle valve 15 is the exhaust velocities of regulating air bellow.During inflation, pressurized air through the check valve of one-way throttle valve 15 and flow regulating valve simultaneously to the airbag aeration of air bellow; During exhaust, the pressurized air in the air bellow can only be through the outside exhaust of flow regulating valve of one-way throttle valve 15.Like this, just can regulate the exhaust velocity of air bellow, thereby avoid exhaust failure.
The principle of work of air bellow control unit LST is:

When a certain air bellow control unit was received the part exhaust instruction of sending from electric control unit, its electromagnetic valve 2 disconnected, and the air bag 10 that cuts off air bellow is connected with the gas circuit of height adjusting valve 14; Electromagnetic valve 3 or 4 actions, the air bag 10 beginning exhausts of air bellow.When the pressure in this air bag 10 is lower than the setting pressure of pressure relay 8, pressure relay 8 actions, the exhaust of expression part is finished, and will disconnect electromagnetic valve 3 or 4.Can the speed of exhaust be by the band noise silencer? flow regulating valve 6,11 regulate.Minimal pressure after the exhaust is provided with by overflow-type pressure regulating valve 5,12.
When a certain air bellow control unit was received from complete exhaust instruction that electric control unit sends, its electromagnetism 2 valves disconnected, and electromagnetic valve 3,4 move simultaneously, and the air bag 10 of air bellow begins exhausts.When the pressure in this air bag 10 was lower than the setting pressure of pressure relay 9, pressure relay 9 action represented that complete exhaust finishes, and disconnects electromagnetic valve 3,4, finishes exhaust.The purpose of the air bag of air bellow being carried out partially or completely exhaust is that its respective carrier unit of protection is not damaged.
When the air bellow et out of order and after repairing, for the air bag of giving air bellow is inflated again, by manual control, send an impulse singla from pressure relay 8 and give the air bellow control unit, allow electromagnetic valve 2 move, till the setting pressure of the pressure in air bag 10 greater than pressure relay 8.
In order to improve the reliability of system, adopt two remaining designs: if there is adjacent compartment to link to each other, so, its adjacent shutoff valve 16 just interconnects, and makes its adjacent height adjustment valve module redundant each other; If there is not adjacent compartment to link to each other by (as end car, automobile), so, a height adjustment valve module in parallel again replaces shutoff valve 16, makes it redundant each other.
