It disconnects, the gas backflow in cover board 6 is discharged through exhaust outlet 93 again by the blowing mouth 92 on gas path control valve 9, pressure release, living
Plug 7 resets under the action of spring 8, and to which piston 7 is detached from the first groove of shift connector 1, shift connector 1 can rotate, this
When driver can shift gears.
The basic principle of protection system described in the utility model is as follows：
The utility model increases a locking mechanism on the gearshift of gearbox 12, is drawn from clutch power-assisted pump 5
Compressed air, and access the locking mechanism；When clutch separation is not thorough or clutch does not detach, clutch power-assisted pump 5 is to lock
Gear mechanism supplies, and locking mechanism locks gearbox shifting device, and driver can not shift gears at this time, after clutch separation, clutch
Boost pump 5 stops supplying to locking mechanism, and the gas pressure release in locking mechanism, gearbox shifting device releases locking, this
When driver can shift gears.Hydraulic oil can also be drawn from table for clutch oil pump 3 or oil pipe 4, and access locking mechanism, it equally can be real
The now locking to gearbox shifting device or releasing locking.Or it is supplied by other means to locking mechanism, the break-make of gas circuit
It is controlled by clutch coupled/separated, above-mentioned function equally may be implemented.
The utility model is suitable for the gearbox of direct manipulation, remote mono-lever control, the manipulation of remote double rod.
The application method of above-mentioned protection system, including,
Pressure source is passed through pressure source by pressure supply pipeline in through-hole on shift control shell 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
It shifts gears the direction movement of connector 1, the protrusion of backset structure contacts locking with the first groove shifted gears on connector 1, 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 logical by pipeline
Disconnected control valve discharge, backset structure are moved to the direction far from shift 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 and connects, 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 shift connector 1, enter with 7 one end of piston of the first groove cooperation
First groove of shift connector 1, connector 1 of shifting gears at this time are locked up, 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 is detached from the first groove of shift connector 1 under the action of 8 elastic force of spring, connector 1 of shifting gears
It can rotate, driver can shift gears at this time.
The mechanical gear box synchronizer of the utility model protects system, can realize clutch pedal 11 and backset structure connection
It is dynamic, when driver steps on clutch pedal 11, backset structure can be released to the locking for connector 1 of shifting gears, gear shift operation can be carried out, taken charge of
When machine does not step on clutch pedal 11, backset structure will shift gears 1 locking of connector can to carry out gear shift operation in driver's cabin
To avoid driver shifts gears in the case where not stepping on clutch and leads to synchronizer premature deterioration, prevented also from vehicle in special road row
Middle phenomenon of losing rank is sailed, drive safety is improved.
