Operation principle：
1st, centre position positioning (neutral positioning)
As in Fig. 2, the first range piston bar 21 is in centre position.The machinery positioning of the positioning end of the first range piston bar 21
Retaining spring 49 is pressed into place kick 45 in the positioning arc groove 47 in the middle of positioning bushing 44 in device, realizes the first range piston
The centre position positioning of bar 21, and detect that the first range piston bar 21 is in bit positions by position sensor 5, now two
Three-way solenoid valve 33 controls the first oil pocket 31 and the second oil pocket 32 is connected with fuel tank.
2nd, interposition moves to left side and puts into gear position (work of putting into gear)
As in Fig. 2, the first range piston bar 21 is in centre position, when two two position, three-way electromagnetic change valves 33 are controlled respectively
The oil extraction of the first oil pocket 31, the oil-feed of the second oil pocket 32 at the two ends of the first range piston bar 21 are made, the first range piston bar 21 is second
Hydraulic fluid pressure overcomes retaining spring 49 to the pressure of place kick 45 to left movement under promoting in oil pocket 32, and two place kick 45 take off
From positioning bushing 44 interfix arc groove 47 and along positioning bushing 44 inwall to left movement, the position until left side is put into gear
(left side extreme position), two place kick 45 reach the left positioner arc groove 47 of positioning bushing 44, and retaining spring 49 will be positioned
Ball 45 press-in positioning arc groove 47 in, now for left side put into gear position positioning, two position, three-way electromagnetic change valve 33 control first
Oil pocket 31 connects fuel tank with the second oil pocket 32, and the stop motion of the first range piston bar 21 is simultaneously maintained at left side and puts into gear position.
3rd, position is put into gear to middle neutral gear position (plucking gear work) in left side
The position if the residing left side of the first range piston bar 21 is put into gear, when hydraulic gear-shifting executing agency carries out plucking gear work,
Described two two position, three-way electromagnetic change valves 33 control respectively the oil-feed of the first oil pocket 31 of hydraulic cylinder, the oil extraction of the second oil pocket 32, the
One range piston bar 21 overcome under the promotion of the pressure of hydraulic oil in the second oil pocket 32 spring to the pressure of place kick 45 to the right
Motion, described two place kick 45 depart from positioning bushing 44 left positioner arc groove 47 and along positioning bushing 44 inwall to
The right interfix arc groove 47 moved up to two arrival bushings of place kick 45, retaining spring 49 is pressed into two place kick 45
In positioning arc groove 47, position sensor 5 detects the first range piston bar 21 and is in bit positions, described two two-position three ways
Solenoid directional control valve 33 controls respectively the first oil pocket 31 of hydraulic cylinder, the connection fuel tank of the second oil pocket 32, completes to pluck and keeps off and keep neutral
Positioning.
Each range piston bar operation principle is identical, and the collaboration under the control of the default Shifting of control system completes to change
Gear performs work, repeats no more here.
4th, change when the interlocking between piston rod
As shown in figure 5, work as having one in the first range piston bar 21, the second range piston bar 22 and the 3rd range piston bar 23
When individual range piston bar carries out gearshift work, the range piston bar will promote mutual lock shaft 61 to snap in two other range piston bar
In interlock slot 62 so as to which its two range piston bar is stuck, and reaches interlocking effect.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes
Change and improvement is both fallen within scope of the claimed invention.The claimed scope of the invention by appending claims and its
Equivalent thereof.
