The utility model discloses a pneumatic AMT system emergency separation clutch controlling device of wheeled armored vehicle's theory of operation is:
when the pneumatic AMT system normally works, the clutch emergency control valve is in a closed state, the pedal type inflating pump is in a locked state, and the clutch of the pneumatic AMT system is operated by a computer gear shifting controller (TCU) through the clutch working cylinder control valve. At the moment, the two-way check valve 7 closes a passage from the clutch emergency control valve 2 to the working cylinder under the action of air pressure; the passage of the clutch cylinder control valve 6 to the cylinder is connected.
When the engine needs to be started at the low temperature of-43 ℃, a driver firstly opens the clutch emergency control valve 2, then the driver tramples a pedal type inflating pump to inflate the working cylinder 9 (AMT system clutch), so that compressed air in the inflator (inflating pump) passes through the clutch emergency control valve 2 to the two-way one-way valve 7 through a pipeline, and the two-way one-way valve closes a passage from the clutch working cylinder control valve 6 to the working cylinder under the action of air pressure; the passage of the clutch emergency control valve 2 to the working cylinder is connected. As the number of steps increases, the clutch is quickly disengaged when the air pressure to the cylinder is sufficiently high. The engine of the vehicle is ensured to be easy to start under the low temperature condition of minus 43 ℃; after the vehicle engine is started, the driver can enable the clutch to be smoothly and softly engaged by manually controlling a clutch emergency control valve in the emergency release clutch operating device of the pneumatic AMT system.
Because the clutch can not be separated by the air pressure of the whole vehicle gas storage cylinder under the low temperature condition of-43 ℃, the design of the pipeline is selected by the model selection of the emergency control valve, the modification of the pedal type inflating pump and the selection of the pipeline. The device utilizes a pedal type inflating pump arranged at an original clutch emergency pedal to inflate a clutch working cylinder of the AMT system, so that the working cylinder pushes a clutch separating arm to further completely separate the clutch, and the vehicle engine is ensured to be easily started under the low-temperature condition of-43 ℃; after the vehicle engine is started, the driver can enable the clutch to be smoothly and softly engaged by manually controlling a clutch emergency control valve in the emergency release clutch operating device of the pneumatic AMT system.
The working cylinder 9 is internally provided with a piston which moves under the action of air pressure, the piston pushes the connected parts, and the clutch is quickly separated.
