[embodiment]
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Embodiment 1
Be conventional transmission case handle structure sketch see Fig. 1 and Fig. 2, Fig. 1, Fig. 2 is operating mechanism of the present invention local sketch, and both maximum is distinguished as, and former gear box operating device increases a cylinder piston actuator 4.When tracheae 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, removes the restriction to shifting shaft.
The gas circuit of whole system connects see Fig. 3 or Fig. 4.A break-make air valve 2 is increased as control air valve at operator 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-strainer 7 or the car load source of the gas of gearbox by gas inlet tube 1, when let slip the clutch 8, after clutch is separated completely, this air valve 2 is died, and the gas outlet tube 3 of this air valve connects the lock-up cylinder of gearbox.
Air inlet pipeline break-make and the clutch working state of lock-up cylinder are closely related, control air valve 2 and ensure when the complete separation condition lower pipeline of clutch is disconnected (or logical).Sleeve mechanism ensure driver step on clutch power cut off completely after could engage a gear.
The operator cabin clutch pedal position of the present invention on-off valve setting up an on-off valve or utilize certain model clutch power-assisted pump to carry is as the control valve of the main gas circuit of this programme, driver steps on clutch, valve is " leading to " or " breaking ", (concrete switching state is linked up by car load factory and gearbox factory and is determined), machinery is opened, very simply.Stopper actuator is a simple cylinder piston mechanism, can be designed to " ventilation unlocks " (Fig. 5 structure) or " unblock of dying " (Fig. 2 structure).If break-make air valve is " leading to ", then adopts " ventilation unlocks " structure, if break-make air valve is " breaking ", then adopt " unblock of dying " structure.
Working procedure:
For " unblock of dying " of embodiment 1, see Fig. 2:
Gearbox 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, tracheae 3 does not have gas, the yet not gas of the lock-up cylinder on gear box operating device, piston 5 return under the action of the spring of lock-up cylinder, piston external part removes 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 engage a gear.
Embodiment 2 is " ventilation unlocks ":
As shown in Figure 5, piston 5 is not when tracheae 3 has gas, and 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 engage a gear.When tracheae and cylinder have gas time, piston 5 customer service spring force under atmospheric pressure effect is return to away from shifting shaft side, and that removes shifting shaft 6 is locked, and shifting shaft 6 can rotate, and driver can engage a gear.
Above content is only and technological thought of the present invention is described; protection scope of the present invention can not be limited with this; every technological thought proposed according to the present invention, any change that technological scheme basis is done, within the protection domain all falling into claims of the present invention.
