Module 1 is that switching solenoid valve 2.1 is powered.Switching solenoid valve 2.1 is generally not charged；When vehicle is braked, 120 type distributing valves 3.2
Lead to the pipeline of checking cylinder 3.4 pressure air touch first switching solenoid valve 2.1 it is electric.
In the case of switching solenoid valve 2.1 is uncharged, operation principle of the invention is as follows：
When Train line charging, acted on through 120 type distributing valves 3.2, the pressure air of train pipe be filled with auxiliary reservoir 3.7,
Alleviate reservoir 3.8 to acceleration after auxiliary reservoir 3.7 to inflate.
When goods train is braked, the pressure air in auxiliary reservoir 3.7 is exported through 120 type distributing valves 3.2, into checking cylinder
3.4, there are following two operating modes：
When the test goods train of weight measurement mechanism 3.6 is in heavy condition, weight measurement mechanism 3.6 causes checking cylinder 3.4 and drop
Pressure reservoir 3.5 is not connected, and is now loaded vehicle pressure in checking cylinder 3.4.
When the test goods train of weight measurement mechanism 3.6 is in Light Condition, weight measurement mechanism 3.6 makes checking cylinder 3.4 and decompression
Reservoir 3.5 is communicated；When goods train is braked, the pressure air of auxiliary reservoir 3.7 leads to checking cylinder 3.4 via mechanical proportional valve 3.3,

Change the size of brake force, the pressure that checking cylinder 3.4 will act on its piston by changing air pressure in checking cylinder 3.4
Power air is delivered on brake shoe through base apparatus, train is produced braking action.
When goods train release of brake, accelerate to alleviate the level pressure air in reservoir 3.8 through the nematic of 120 type distributing valve 3.2
Car pipe adverse current, produces partial Pressure, accelerates the alleviation of adjacent lorry, so as to improve the release propagation rate of full train, it is ensured that alleviation
Uniformity.
In the case where switching solenoid valve 2.1 is powered, operation principle of the invention is as follows：
When vehicle is braked, the pressure air that 120 type distributing valves 3.2 lead to the pipeline of checking cylinder 3.4 touches switching electricity first
Magnet valve 2.1 obtains electric, and proportion magnetic valve 2.2 and the tunnel of relay valve 2.3 1 enter pressure air, and another road flows to mechanical empty and load and adjusted
Engagement positions gas circuit is switched magnetic valve 2.1 and closed.The empty and load braking mode set in braking electronic control unit 2.4, simultaneously
According to the change of load transducer at bolster 2.5, the signal of velocity sensor 2.6 of 4 axletrees, to control to brake proportion magnetic valve
2.2 valve opening degree.Because the flow of proportion magnetic valve 2.2 is smaller, it is necessary to which installing relay valve 2.3 additional in path carrys out amplified flow.
Finally, change and enter the pressure air size pressure of checking cylinder 3.4 to adjust brake force, reach vehicle empty and load brake equipment
And skidproof effect.
Train line charging, the operation principle of goods train release of brake are identical with the uncharged situation of switching solenoid valve 2.1.
