Piston 7 moves under the action of pressure source to close to the direction of gearshift connector 1, and when clutch is in discrete state, pipeline leads to
Disconnected control valve control pressure supply pipeline disconnects, and piston 7 moves under the elastic force effect of spring 8 to the direction away from gearshift connector 1.
The pressure source of the present invention can select hydraulic oil or compressed gas, and pressure source can be table for clutch oil pump 3, oil pipe 4
Or clutch power-assisted pump 5；As shown in Figure 3.
As shown in figure 4, in this example, clutch power-assisted pump 5 is used to provide compressed gas as pressure source for protection system,
Pressure supply pipeline uses tracheae 10, and pipeline on-off control valve uses the gas circuit control with air inlet 91, blowing mouth 92 and exhaust outlet 93
Valve 9 processed, gas path control valve 9 are arranged on the lower section of clutch pedal 11, its opening and closing is controlled by clutch pedal 11.Clutch pedal
11 when not stepping on, and when gas path control valve 9 is opened, the air inlet 91 of gas path control valve 9 connects tracheae 10 with blowing mouth 92, clutch
Device boost pump 5 is passed through gas to gearshift；When stepping on clutch pedal 11, the air inlet 91 and blowing mouth 92 of gas path control valve 9
Disconnecting, blowing mouth 92 is connected with exhaust outlet 93, and the gas backflow in gearshift is discharged through exhaust outlet 93 again by blowing mouth 92,
Pressure in gearshift is released.Specifically, do not step on clutch pedal 11 or step on when being not thorough, clutch do not separate or point
From being not thorough, gas path control valve 9 controls tracheae 10 to connect, and clutch power-assisted pump 5 is supplied to cover board 6, and driving piston 7 connects to gearshift
First 1 direction movement, one end that 7 and first groove of piston coordinates enter the first groove of gearshift connector 1, connector 1 of shifting gears at this time
It is locked out, driver can not shift gears；Treat that clutch pedal 11 is operated, after clutch separation, gas path control valve 9 disconnects tracheae 10,
Gas backflow in cover board 6 is discharged through exhaust outlet 93 again by the blowing mouth 92 on gas path control valve 9, and pressure release, piston 7 exists
Resetted under the action of spring 8, so that piston 7 departs from the first groove of gearshift connector 1, gearshift connector 1 can rotate, at this time driver
It can shift gears.
The basic principle of protection system of the present invention is as follows：
The present invention increases a locking mechanism on the gearshift of gearbox 12, draws and compresses from clutch power-assisted pump 5
Air, and access the locking mechanism；When clutch separation is not thorough or clutch does not separate, clutch power-assisted pump 5 is to backset machine
Structure supplies, and locking mechanism pins gearbox shifting device, and driver can not shift gears at this time, clutch power-assisted after clutch separation
Pump 5 stops supplying to locking mechanism, and the gas pressure release in locking mechanism, gearbox shifting device releases locking, takes charge of at this time
Machine can shift gears.Hydraulic oil can also be drawn from table for clutch oil pump 3 or oil pipe 4, and access locking mechanism, can equally realized pair
The locking of gearbox shifting device releases locking.Or supplied by other means to locking mechanism, the break-make of gas circuit lean on from
Clutch coupled/separated controls, and can equally realize above-mentioned function.
The present invention is suitable for direct manipulation, remote mono-lever control, the gearbox of remote double rod manipulation.
Mechanical gear box synchronizer guard method based on above-mentioned protection system, including,
Pressure source is passed through pressure source by pressure supply pipeline into the through hole on shift control housing 2；
When not stepping on clutch pedal, pressure supply pipeline is in connected state, and backset structure is under the action of pressure source to close
Shift gears the direction movement of connector 1, the protrusion of backset structure contacts locking with the first groove on connector 1 of shifting gears, at this time cannot be into
Row gear shift operation；
When stepping on clutch pedal 11, pipeline on-off control valve cuts off pressure supply pipeline, and the gas in through hole is led to by pipeline
Disconnected control valve discharge, backset structure are moved to the direction away from gearshift connector 1, can carry out gear shift operation at this time.
Specifically, in this example：
When not stepping on clutch pedal 11, gas path control valve 9 controls tracheae 10 to connect, and clutch power-assisted pump 5 is supplied to cover board 6
Gas, piston 7 move under the action of gas pressure to the direction of gearshift connector 1, enter with 7 one end of piston that the first groove coordinates
First groove of gearshift connector 1, connector 1 of shifting gears at this time are locked out, and driver can not shift gears；When stepping on clutch pedal 11, gas circuit control
Valve 9 processed disconnects tracheae 10, and clutch power-assisted pump 5 stops supplying to cover board 6, and the gas pressure at piston 7 is controlled by gas circuit
The exhaust outlet 93 of valve 9 discharges, and piston 7 departs from the first groove of gearshift connector 1 under the action of 8 elastic force of spring, and gearshift connector 1 can
To rotate, driver can shift gears at this time.
