Described cylinder piston actuator includes cylinder and piston, and groove is offered in position corresponding with the external part of piston on shifting shaft, and the external part of piston can limit shifting shaft with groove fit and rotate; Gas outlet tube is connected to cylinder air inlet, and when break-make air valve is ventilated, gas is entered cylinder by gas outlet tube, promotes piston to stretch out and limits shifting shaft rotation with groove fit; When break-make air valve is died, piston return under the effect of the spring being sheathed on piston rod, release the restriction to shifting shaft.
Described cylinder piston actuator includes cylinder and piston, and groove is offered in position corresponding with piston on shifting shaft, and piston stretches out and can limit shifting shaft rotation with groove fit; Gas outlet tube is connected with cylinder passage; When break-make air valve is ventilated, gas is entered cylinder by gas outlet tube, promotes piston return, releases the restriction to shifting shaft; When break-make air valve is died, piston stretches out under the effect of the spring being sheathed on piston rod, limits shifting shaft with groove fit and rotates.
Compared with prior art, this utility model has the advantages that
This utility model adopts machinery--pneumatic mechanism, all of pneumatic element is mechanical type, it is provided without electric electronic element, mechanical structure high-low temperature resistant, by electromagnetic interference, humidity and dust, be suitable for various bad working environments, and component structure that this utility model adopts is all very simple, for machine components, structure its reliability more simple is more high.
Further, the number of elements that this utility model meal adopts is few and simple, compares the change speed gear box cost increase not protecting device limited, the therefore better economy of whole device.
Further, this utility model is fluting on horizontal shifting shaft, the external part adopting piston can with the rotation of only small cylinder force restriction shifting shaft with groove fit, therefore cylinder can design only small ingeniously, the position that it is suitable that cylinder piston actuator can be arranged on manipulation device easily and flexibly. And, almost all of mechanical gearbox has a horizontal gear level (axle), performs spinning movement when gearshift, and therefore this utility model is of wide application general.

[detailed description of the invention]
Below in conjunction with accompanying drawing, this utility model is described in further detail:
Embodiment 1
Being conventional transmission case handle structure sketch referring to Fig. 1 and Fig. 2, Fig. 1, Fig. 2 is operating mechanism schematic partial diagram of the present utility model, and both maximum is distinguished as, and increases a cylinder piston actuator 4 on former gear box operating device. When trachea 3 and cylinder have gas time, atmospheric pressure overcomes spring force, and piston 5 stretches out, and shifting shaft 6 has corresponding groove, and both act on the rotation of restriction shifting shaft 6; When cylinder not gas time, piston rod is self-return under the action of the spring, releases the restriction to shifting shaft.
The gas circuit of whole system connects referring to Fig. 3 or Fig. 4. A break-make air valve 2 is increased as controlling air valve at driver's cabin clutch pedal 8 place (Fig. 3) or boost pump 9 place (Fig. 4), the source of the gas of this air valve connects air filter 7 or the car load source of the gas of change speed gear box by gas inlet tube 1, when let slip the clutch 8, after clutch is kept completely separate, this air valve 2 is died, and the gas outlet tube 3 of this air valve connects the lock-up cylinder of change speed gear box.
The air inlet pipeline break-make of lock-up cylinder is closely related with clutch duty, controls air valve 2 and ensures that when clutch is kept completely separate condition lower pipeline be disconnected. Sleeve mechanism ensures that driver steps on could hang shelves after clutch power completely cuts through.
A switch valve or the switch valve that utilizes certain model clutch power-assisted pump the to carry control valve as the main gas circuit of this programme is set up in this utility model driver's cabin clutch pedal position, driver steps on clutch, switch valve is " leading to " or " breaking ", (concrete on off operating mode is linked up decision by car load factory with change speed gear box factory), machinery is opened, very simply. Stopper actuator is a simple cylinder piston mechanism, may be designed as " ventilation unlocks " (Fig. 5 structure) or " unblock of dying " (Fig. 2 structure). If switch valve is " leading to ", then adopt " ventilation unlocks " structure, if switch valve is " breaking ", then adopt " unblock of dying " structure.
Work process:
Change speed gear box is in shift process, driver's let slip the clutch 8, the air valve 2 at pedal place or the air valve 2 at boost pump 9 place are died, now, trachea 3 does not have gas, and the lock-up cylinder on gear box operating device is also without gas, piston 5 return under the action of the spring of lock-up cylinder, piston external part releases the locking to gear level 6, and gear level 6 can rotate, and namely driver can put into gear.
If driver's not stepping on clutch, control air valve 2 state at pedal place or boost pump 9 place is logical, then lock-up cylinder work, and piston 5 external part is by locked for gear level 6, and gear level can not rotate, and driver can not hang shelves.
Embodiment 2:
As it is shown in figure 5, piston 5 is not when trachea 3 has gas, due to the promotion of spring force, piston 5 acts on mutually with shifting shaft 6 groove, and shifting shaft can not rotate, and driver can not hang shelves. When trachea and cylinder have gas time, piston 5 customer service spring force under atmospheric pressure effect is return to away from shifting shaft side, releases locked to shifting shaft 6, and shifting shaft 6 can rotate, and driver can hang shelves.
Above content is only explanation technological thought of the present utility model; protection domain of the present utility model can not be limited with this; every according to the technological thought that the utility model proposes, any change done on technical scheme basis, each fall within the protection domain of this utility model claims.
