Described stop valve 5 is touched contact 5-3 by stop valve contact shifting block 14 and realizes the closedown of stop valve 5, preferably ends
It is provided with V-groove with contact 5-3 cooperation position, even if now stirring high and low shift switch change-over valve core the most not on valve contact shifting block 14
Can move, it is achieved that stop valve is not opened just cannot the purpose of gear shift.
The operation principle of multi-speed transmission odd-side compressed-air shifting control system assembly and having the beneficial effect that:
When gear shifting handle switch is positioned at high-grade end, gear shifting handle top grade gas outlet is connected with gear shifting handle air inlet, is changed
Shelves handle top grade gas outlet controls mouth connection by connecting trachea and reversal valve top grade, promotes change-over valve core action, makes commutation
Valve air inlet is connected with reversal valve top grade gas outlet, and reversal valve top grade gas outlet is high-grade with gear shifting cylinder assembly by high-grade trachea
Side joint leads to, and promotes gear shifting cylinder assembly piston to high-grade lateral movement；When bat-handle switch is positioned at low grade, handle low grade gas outlet with
Handle air inlet is connected, and handle low grade gas outlet controls mouth by trachea and reversal valve low grade and connects, and promotes change-over valve core to move
Making, make reversal valve air inlet connect with reversal valve low grade gas outlet, reversal valve low grade gas outlet is by low-grade trachea and gear shift gas
Cylinder low grade side joint leads to, and promotes gear shifting cylinder assembly piston to low-grade lateral movement.
When stop valve contact shifting block rotates, the V-groove pressure that stop valve contact is cut off on the shifting block of valve contact, stop valve
Closing, stop valve gas outlet not gas, also will not move even if now stirring high and low shift switch change-over valve core, it is achieved that cut-off
Valve is the most open-minded, it is impossible to the purpose of gear shift.Stop valve contact shifting block is connected with main tank gearshift, only exists at main tank gearshift
Under neutral position state, stop valve contact just can not be cut off the shifting block pressure of valve contact, it is achieved the mutual lock control of major-minor case.
