Ring flange is connected with the vertical drive rod mounting hole (8-1) of tapered end (8)；The main function of vertical hydraulic cylinder (17) is to make tapered end
(8) it can move up and down in the vertical direction, to realize the locking and unlock between axle box shell and slide block assembly (1)；
The controller (14) is mounted on the framework of gauge-changeable bogie, the input terminal and data processing mould of controller (14)
Block (13) connection, the output end of controller (14) respectively with No.1 transverse hydraulic cylinder (15), No. two transverse hydraulic cylinders (16) and vertical
It is connected to the solenoid valve of hydraulic cylinder (17), the diaphragm pressure that the controller (14) is transmitted according to data processing module (13)
It sensor (10), stay-supported type displacement sensor (11) and locks the digital signal of location switch (12) and controls each hydraulic cylinder
Expanding-contracting action, so that gauge-changeable bogie be made to be automatically performed the transformation of the unlock and locking and wheel of wheel under different gauges
Movement.
2. a kind of active orbit changing method of gauge-changeable bogie, the process employs a kind of change rails according to claim 1
Active rail changing device away from bogie, which is characterized in that comprising the following specific steps
Step 1: vehicle is with speed V0, speed V0The maximum speed V for being consistently less than or allowing equal to gauge changing processmax, slowly
It drives into, carrying boots (7) comes into contact with ground loading mechanism, by the diaphragm pressure mounted in two sides axle box carrying boots (7) below
Sensor (10) detection carrying pressure information, when the load information that two sides thin-film pressure sensor (10) obtain is stablized, table
Paddle wheel is to having unloaded；
Step 2: after wheel unloading, the push rod that controller (14) controls vertical hydraulic cylinder (17) is moved up, to drive on tapered end (8)
Lock is transfered from one place to another under escort, when tapered end location switch (12) detects unlock signal in place, controls vertical hydraulic cylinder (17) stop motion, and protect
Hold unlocked state；
Step 3: after the completion of unlock, controller (14) control No.1 transverse hydraulic cylinder (15) and No. two transverse hydraulic cylinder (16) are pushed away
Bar pushes and pulls slide block assembly (1), to change the wheelspan of wheel, when stay-supported type displacement sensor (11) detects slide block assembly (1)
When reaching specified gauge position, controller (14) controls No.1 transverse hydraulic cylinder (15) and No. two transverse hydraulic cylinders (16) stop moving
Make；
Step 4: after the completion of gauge changing, the push rod that controller (14) controls vertical hydraulic cylinder (17) is moved down, to drive tapered end
(8) locking is moved down, when tapered end location switch (12) detects locking signal in place, vertical hydraulic cylinder (17) is controlled and stops fortune
It is dynamic, and maintain the lock status；
Step 5: after the completion of locking, gauge-changeable bogie is driven out to ground loading device, passes through thin-film pressure sensor (10)
Pressure signal may determine that axle box unloads, then wheel carries again, and the change rail process of entire gauge-changeable bogie is completed.
