[0022] In this embodiment, a comprehensive training platform for a railway freight car brake system realizes the control of vehicle initial air charging, pressure reduction braking, and air charging relief through the change of air pressure of the brake hose assembly 101.

[0023] Initial filling: The information collection and control system 3 controls the pressurized air to fill the brake main pipe 103 through the brake hose assembly 101 and the angled valve 102. The pressurized air is filled into the control valve 106 through the shut-off valve 104, pipe one 114, and the intermediate body 105. The control valve 106 controls the pressurized air to fill into the auxiliary air cylinder 107 through pipe two 115, and then into the double-chamber air cylinder 108 through pipe three 116, up to 500KPa.

[0024] Pressure-reducing braking: Information collection and control system 3 controls the discharge of pressurized air from brake main pipe 103 to the atmosphere through angled valve 102 and brake hose assembly 101. The pressure-reducing signal is transmitted to control valve 106 via pipe 1 114, shut-off valve 104, and intermediate body 105. Sensing valve 109 and pressure-limiting valve 112 utilize the pressurized air from auxiliary air cylinder 107 to drive sensing valve 109, which measures the vehicle load signal. Simultaneously, based on the vehicle load signal, pressurized air from auxiliary air cylinder 107 is directed through sensing valve 109 and pressure-limiting valve 112 to flow through pipes 2 115, 4 117, 5 118, and 6 110 into the right air cylinder of dual-chamber air cylinder 108. Pressurized air is then fed into brake cylinder 113 via pipes 2 115, 4 117, and 7 111. The pressurized air pushes the piston of brake cylinder 113 to the left. Then the piston push rod 201 moves to the left, the piston push rod 201 drives the piston push rod round pin 202 to move to the left, pushing the front lever 203 of the brake cylinder to use the brake adjuster connecting round pin 204 as the fulcrum to pull the first pull rod 206 to move to the right, and at the same time use the 205 round pin as the fulcrum to drive the brake adjuster 215 to move to the left, the first pull rod 206 pulls the round pin 205 and the upper part of the moving lever 207 to move to the right, and the moving lever 207 rotates around the bogie fixed seat round pin 208 as the center, driving the brake beam support round pin 211 and the brake beam 21 0 moves to the left, the brake beam 210 drives the brake shoe 220 to hold the wheel tightly, the brake cylinder front lever 203 pulls the brake cylinder front lever and the brake adjuster connecting round pin 204 and the brake adjuster 215 to move to the left, and the brake adjuster 215 is shortened under the joint action of the control lever 212 and the control rod 214. The brake adjuster 215 pulls the brake cylinder rear lever 217, and the brake cylinder rear lever 217 is fixed to the upper part of the brake cylinder fixed support seat 218 through the two-position upper pull rod fixed support seat 219. The brake cylinder fixed support seat 218 is fixed on the platform and does not move.

[0025] Air filling relief: Information collection and control system 3 controls pressurized air through brake hose assembly 101 and angled valve 102 to fill brake main pipe 103. Simultaneously, pressurized air from dual-chamber air cylinder 108 is introduced into brake main pipe 103 through pipe three 116 and pipe one 114, accelerating the pressure rise in brake main pipe 103. Pressurized air from brake main pipe 103 is introduced into control valve 106 through shutoff valve 104, pipe one 114, and intermediate element 105. Control valve 106 controls pressurized air through pipe two 115 to auxiliary air cylinder 107 and pipe three 116 to dual-chamber air cylinder 108. Pressurized air in the brake cylinder enters control valve 106 through pipe seven 111 and pipe four 117, and is discharged to the atmosphere through the exhaust port of control valve 106. The piston in brake cylinder 113 returns under the action of the return spring.

[0026] The touch integrated controller 314 controls the leakage blocking controller 1 301 and the leakage blocking controller 2 302 to open and close independently, which is used to simulate the physical demonstration of the two states of air leakage and no air leakage between the auxiliary air cylinder 107 and the intermediate body 105;

[0027] The touch integrated controller 314 controls the leakage blocking controller 303 and the leakage blocking controller 4 304 to open and close separately, which is used to simulate the physical demonstration of the two states of air leakage and air non-leakage between the intermediate body 105 and the air cylinder connected to the double-chamber air cylinder 108;

[0028] The touch integrated controller 314 controls the leakage blocking controller 5 305 and the leakage blocking controller 6 306 to open and close independently, which is used to simulate the physical demonstration of the two states of air leakage and no air leakage between the shut-off valve 104 and the intermediate body 105;

[0029] The touch-integrated controller 314 controls the leakage-blocking controller 7 307 and the leakage-blocking controller 8 308 to open and close independently, simulating the physical demonstration of the two states of air leakage and no air leakage between the pressure-limiting valve 112 and the brake cylinder 113;

[0030] Pressure sensor 1 309 , pressure sensor 2 310 , pressure sensor 3 311 , and pressure sensor 4 312 are used to respectively collect the pressures of the auxiliary air cylinder 107 , the air cylinder connected to the intermediate body 105 and the dual-chamber air cylinder 108 , the brake cylinder 113 , and the brake main pipe 103 under the aforementioned various conditions and display them on the integrated touch controller 314 ;

[0031] The displacement sensor 313 is used to collect the piston stroke inside the brake cylinder 103 under the above-mentioned various states and display it on the touch-integrated controller 314.
