Embodiment
For further understanding technology contents of the present utility model, characteristics and effect, enumerate following example now, and conjunction with figs. is described in detail as follows:
With reference to accompanying drawing 1 and Fig. 2.
A kind of numerical digit ecp gearshift comprises valve body, valve rod, piston and solenoid valve, and valve rod and 2 pistons are arranged in the valve body, and valve body is fixed on the valve seat of gearbox by a connecting plate.4 solenoid valve break-make modes are connected on the passage of piston both sides gas in the valve body, and the displacement distance of control valve valve rod is identical between each gear of the displacement distance of valve rod and gearbox.Valve rod has the pin that is connected with gearbox control valve valve rod.
The concrete linkage structure and the working procedure of present embodiment:
Present embodiment is a kind of multidigit ecp gearshift, and its structure mainly comprises connecting plate 1, solenoid valve 2, moveable piston 3, valve body 4, valve rod 5, piston 6 and the joint 8 that is connected with gearbox manipulation valve rod, pin 9 and locking nut 7 compositions.
Below in conjunction with accompanying drawing to the shift process brief description:
1. a retaining advances: solenoid valve M2 and the solenoid valve M4 air inlet of switching on simultaneously, valve rod 5 moves to moveable piston 3 under the effect of atmospheric pressure, because the pressure on moveable piston 3 right sides acts on the power in its left side greater than valve rod, make it keep motionless in present position, valve rod 5 then is in the F1 place, realizes advancing a retaining;
2. two retainings advance: the solenoid valve M2 air inlet of switching on, and next directly moves to the F2 place, 2 retainings of realizing advancing to valve rod 5 in the effect of atmospheric pressure;
3. neutral: solenoid valve M1 and the solenoid valve M3 air inlet of switching on simultaneously, because the pressure in piston 4 left sides is greater than the power of right side valve rod, it is motionless to make valve rod 5 get back to N place under the effect of air pressure, the realization neutral;
4. retaining falls back: the solenoid valve M3 air inlet of switching on, next directly moves to the R place to valve rod 5 in the effect of atmospheric pressure, thereby realizes falling back retaining.
The gearshift mode adopts electric gearshift.No matter valve rod and structure of piston have determined this mechanism to be in all gear shift operation flexibly of what gear, do not have stuck phenomenon.Gearshift is by the work of handle control electromagnetic valve, and in complete machine walking and working procedure, the shift signal control gearshift solenoid valve of shift handle makes machine run in required gear.
