P mouthfuls of air inlet of valve 14 connections, gas control air valve 14 execute mouth A mouthful pass through two gas channels respectively with the gas outlet of check valve 15 and
The rod chamber of shifting cylinder 11 is connected to, and P mouthfuls of air inlet of second electromagnetic gas valve 13 are connected to gas bag 1, the second electromagnetic gas valve
A mouthfuls of mouth of execution of 13 are connected to K mouthfuls of the control mouth of gas control air valve 14 with the air inlet of check valve 15 respectively by two gas channels；
The crankshaft signal disc side of engine is arranged in the speed probe 6, and speed probe 6 is used to measure to start
The revolving speed of machine, the first pressure sensor 5 are connected to the mouth A mouthfuls of rodless cavity to butterfly valve cylinder 3 that execute of exhaust butterfly switch 2
Gas channel on, the pressure signal of the rodless cavity for receiving butterfly valve cylinder 3, when braking is exhausted, the nothing of butterfly valve cylinder 3
Rod cavity has pressure, and when exhaust brake releases, the rodless cavity of butterfly valve cylinder 3 does not have pressure, the second pressure sensor 10
It is connected on the gas channel for executing the mouth A mouthfuls of rodless cavity to shifting cylinder 11 of the first electromagnetic gas valve 9, for receiving shifting cylinder
The pressure signal of 11 rodless cavity, the third pressure sensor 12 are connected to A mouthfuls of the execution mouth extremely shift gas of gas control air valve 14
On the gas channel of the rod chamber of cylinder 11；For receiving the pressure signal of the rod chamber of shifting cylinder 11.
The speed probe 6, first pressure sensor 5, second pressure sensor 10, third pressure sensor 12,
Terminals K1, K2 of terminals K1, K2 of one electromagnetic gas valve 9 and the second electromagnetic gas valve 13 are electrically connected with master controller 7, when turn
Fast sensor 6 measures obtained engine speed less than 1600 r/min and first pressure sensor 5, second pressure sensor 10
The terminals K1 of first electromagnetic gas valve 9 of the control of master controller 7 is obtained electric when all having pressure, when first pressure sensor 5 does not have
When pressure master controller 7 control the first electromagnetic gas valve 9 terminals K2 and the second electromagnetic gas valve 13 terminals K2 obtain it is electric, when turn
Fast sensor 6 measures obtained engine speed less than 1600 r/min and first pressure sensor 5 has pressure, second pressure
Master controller 7 controls the terminals K1 of the second electromagnetic gas valve 13 when sensor 10 and third pressure sensor 12 do not have pressure
It obtains electric.
Under normal circumstances, without exhaust brake, i.e. exhaust brake is vented holding for butterfly switch 2 in the state of releasing at this time
A mouthfuls of row mouth communicate with atmosphere, and first pressure sensor 5 does not have pressure, and master controller 7 controls the wiring of the first electromagnetic gas valve 9
The terminals K2 of end K2 and the second electromagnetic gas valve 13 obtains electric, P mouthful of the air inlet of such first electromagnetic gas valve 9 and mouth A mouthfuls of phase of execution
Logical, mouth A mouthfuls with execution of P mouthfuls of air inlet of the second electromagnetic gas valve 13 is not communicated with, and the pressed gas in gas bag 1 cannot be through the second electromagnetism
Air valve 13 enters K mouthfuls of control mouth of gas control air valve 14, and mouth A mouthfuls with execution of P mouthfuls of air inlet of gas control air valve 14 communicates.At this moment it drives
Member's operation shift reversal valve 8, communicates P mouthfuls of shift 8 air inlet of reversal valve mouth A mouthfuls with execution, vehicle hangs over three and blocks, and changes at this time
The rodless cavity for keeping off cylinder 11 has pressure, and the rod chamber of shifting cylinder 11 does not have pressure, therefore second pressure sensor 10 has
There are pressure, third pressure sensor 12 not to have pressure, communicates P mouthful of 8 air inlet of gear shift reversal valve mouth B mouthfuls with execution, vehicle
One is hung over to block, the rodless cavity of shifting cylinder 11 does not have pressure at this time, and the rod chamber of shifting cylinder 11 has pressure, therefore the
Two pressure sensors 10 do not have pressure, third pressure sensor 12 has pressure, make P mouthfuls of 9 air inlet of gear selecting reversal valve and hold
Mouth B mouthfuls of A mouthfuls of row mouth and execution are not communicated with, and the rod chamber and rodless cavity of shifting cylinder 11 do not have pressure, and vehicle hangs over two
It blocks, second pressure sensor 10 and third pressure sensor 12 do not have pressure at this time；
Braking is exhausted when vehicle hangs over three gears, mouth A mouthfuls with execution of P mouthfuls of air inlet of exhaust butterfly switch 2 communicates,
Pressed gas in gas bag 1 arrives the rodless cavity of butterfly valve cylinder 3 through exhaust butterfly switch 2, and first pressure sensor 5 has pressure,
Mouth A mouthfuls with execution of P mouthfuls of shift 8 air inlet of reversal valve communicates, and the pressed gas in gas bag 1 is through the first electromagnetic gas valve 9 to shift gas
The rodless cavity of cylinder 11, second pressure sensor 10 have pressure, if the engine speed that the measurement of speed probe 6 at this time obtains is small
In 1600 r/min, the terminals K1 that master controller 7 can control the first electromagnetic gas valve 9 obtains electric, the execution mouth of the first electromagnetic gas valve 9
A mouthfuls communicate with atmosphere, and at this moment the rod chamber of shifting cylinder 11 does not also have pressure, keep the rod chamber of shifting cylinder 11 and rodless cavity equal
Without pressure, second pressure sensor 10 and third pressure sensor 12 do not have pressure yet, and vehicle automatically switches to two
Gear.Therefore vehicle is switched to bottom gear from top gear automatically.
At this point, if vehicle still has pressure in exhaust brake condition, that is, first pressure sensor 5, and speed probe 6 is surveyed
The engine speed measured is still less than 1600 r/min, due to second pressure sensor 10 and third pressure sensor 12 at this time
Do not have pressure, master controller 7 control the second electromagnetic gas valve 13 terminals K1 obtain it is electric, such second electromagnetic gas valve 13 into
P mouthfuls of port with execute mouth A mouthful and communicate, the pressed gas in gas bag 1 by the second electromagnetic gas valve 13 entrance gas control air valve 14 control
The air inlet of K mouthfuls of donsole and check valve 15 by entering the rod chamber of shifting cylinder 11 after check valve 15, and makes gas control air valve 14
To make P mouthfuls of air inlet of gas control air valve 14 to be not communicated with mouth A is executed, the pressed gas in such gas bag 1 can be through second for movement
Electromagnetic gas valve 13 and check valve 15 reach the rod chamber of shifting cylinder 11, and P mouthfuls of the air inlet of gas control air valve 14 and execution at this time
Mouthful A is not communicated with, the pressed gas in the rod chamber of such shifting cylinder 11 would not by after gas control air valve 14 again through changing
It is communicated to the B mouth of valve 8 with atmosphere, makes the rod chamber of shifting cylinder 11 that there is pressure, the rodless cavity of shifting cylinder 11 does not have pressure
Power, vehicle automatically switch to a gear.Therefore vehicle is switched to bottom gear from top gear automatically.
