As shown in figure 3, the utility model is a kind of loading machine gearbox electric control operation system, including integrated electric manipulates hand
Handle 1, automatically controlled gear shift combination valve 7 and core of a cable 8；The integrated electric control crank 1 is combined with automatically controlled gear shift
Valve 7 is connected by core of a cable 8；The integrated electric control crank 1 is equipped with the structure that slides axially, the structure that slides axially
It is equipped with the switch with KD function.Preferably, the speed change box clutch and automatically controlled 7 cabinet of gear shift combination valve pass through oil
Road pipeline connects (position K shown in Fig. 3).
Wherein, integrated electric control crank 1 employed in the utility model is similar to conventional control crank, and with it is normal
Rule control crank is the difference is that the integrated electric control crank 1 of the utility model is equipped with the structure that slides axially, the axial direction
Slide construction is equipped with the switch with two-way KD function, by the setting of KD functional switch, had both simplified gear shift operation, has reduced labor
Fatigue resistance improves operating comfort, and travel speed and operating efficiency can be improved；Oil consumption can be also reduced simultaneously, loading machine has bright
Aobvious energy-saving effect.
Further, the integrated electric control crank 1 include F1 grade, F2 grades, N grades, R1 grades, R2 grades, i.e., advance 1 grade,
2 grades of advance neutral gear, retreats 1 grade, retreats 2 grades, it can be achieved that the different shifts to loading machine control.
In the utility model embodiment, the automatically controlled gear shift combination valve 7 includes electromagnet 2, shift slide valve 3, resets
Spring 4, overflow valve 6, wherein overflow valve 6 plays overflow voltage-limiting protection.Above-mentioned each component is connected with each other the automatically controlled speed change of composition and changes
Gear combination valve 7 is simultaneously connect with cabinet outside the enclosure, is connected by the oil duct on cabinet with speed change box clutch.(wherein, automatically controlled change
Connection type between quick change gear 7 internal structure of combination valve belongs to existing conventional connection type, and it is not described here in detail).
Further, the integrated electric control crank 1 passes through the electromagnet in harness and automatically controlled gear shift combination valve 7
2 connections control shift 3 position of slide valve by controlling the on-off of electromagnet, realize integrated electric control crank 1 to automatically controlled speed change
The logic control of shift combination valve 7.
In the utility model embodiment, the automatically controlled 7 four shift slide valves 3 in inside of gear shift combination valve, with four electricity
Magnet 2, reset spring 4, overflow valve 6 form the automatically controlled shift combination valve of gearbox, pass through the logic with integrated electric control crank 1
Control is, it can be achieved that the automatically controlled shift of required gearbox.
Further, the automatically controlled gear shift combination valve 7 is also connected with hydraulic pump 5 by box body oil duct, for providing
Pressure oil.
In the utility model embodiment, the integrated electric control crank 1 is connect with electromagnet 2 by core of a cable, into
And shift slide valve 3 is controlled by control electromagnet, so that shift slide valve 3 is in different positions, so that hydraulic pump be made to be provided
Pressure oil supply different clutches.Under the action of pressure oil, clutch is combined, and makes gearbox output power；Clutch
Then not output power is not combined.
The loading machine gearbox electric control operation system of the utility model, the power output of gearbox is by its internal clutch
It is implemented in combination with, its working principle is that: when integrated electric control crank 1 is motionless, speed change box clutch (position shown in K in Fig. 3)
In oil under the effect of reset spring 4, communicate A-T shown in Fig. 3, hydraulic oil pressure release oil return, without pressure in speed change box clutch
Power, is in discrete state, and power does not export；When integrated electric control crank 1 is placed in any shelves in F1 grades, F2 grades, R1 grades, R2 grades
When, output control signal passes to the corresponding electromagnet 2 of automatically controlled gear shift combination valve 7 by core of a cable, corresponding
Electromagnet 2 must be electric, to make the movement of slide valve 3 of shifting gears, communicates P-A shown in Fig. 3, and T mouthfuls of closings, the pressure oil of hydraulic pump passes through
Valve body oil duct -- box body oil duct enters corresponding clutch cavity, and under the action of pressure oil, speed change box clutch is bonding state,
Transmit power.
Non- detailed portion is the prior art in the utility model, therefore no longer does specific introduction.
The loading machine gearbox electric control operation system of the utility model, in use, the KD translative mode in gear commutation:
When integrated electric control crank 1 is placed in F2 grades, advance electromagnet obtain it is electric, at this time driving advance shift slide valve at spool, make pressure
Oil driving 2 grades of clutches of advance combine, and loading machine is in 2 grades of upper walkings of advancing at this time.By KD functional switch, automatically controlled gear shift group
Valve internal logic procedure auto-control is closed, while the 1 grade of electromagnet output electric signal that marches forward, driving are advanced at 1 grade of shift slide valve
Spool combines pressure oil driving 1 grade of clutch of advance, makes loading machine in 1 grade of upper traveling of advancing.When integrated electric control crank
1 when being allocated to reverse drive gear, and automatically controlled gear shift combination valve 7 is defaulted as retreating 2 grades, retreats electromagnet and obtains electric, driving retreats shift and slides
Spool at valve makes pressure oil driving retreat 2 grades of clutches and combines, and loading machine is retreating 2 grades of upper travelings, while automatically exiting from KD shape
State.
Similarly, when loading machine retreat 2 grades it is upper when, when entering KD state by KD functional switch, generated signal and
Oil circuit control it is same as above (R2 (-> break drive shift -> F2 by KD- > R1- > integrated electric control crank and at this moment automatically exit from KD
KD grades of translative mode when state gear changes).
Similarly, signal caused by the other modes of KD translative mode when gear commutates and its oil circuit control are also same as above
State described similar, conversion operation mode is as follows: F2- > by KD- > F1- > by KD- > F2 (exiting KD state)；
F2- > by KD- > F1- > rotation integrated electric control crank to F1- > F1 exits KD state)；
R2- > by KD- > R1- > by KD- > R2 (exiting KD state)；
R2- > by KD- > R1- > rotation integrated electric control crank to R1- > R1 (exiting KD state).
It when loading machine is normal commutation transforming gear mode, does not need by KD functional switch, only operates integrated electric behaviour
Vertical handle 1, realizes that common commutation gear can (F2- > integrated electric control crank 1 breaks reverse gear shift -> R2, R2- > integrated form
Electric control crank 1 breaks drive shift -> F2, F1- > integrated electric control crank 1 and breaks reverse gear shift -> R1, R1- > integrated electric behaviour
Vertical handle 1 breaks drive shift -> F1).
In short, the loading machine gearbox electric control operation system of the utility model can realize the different conversions under different operating conditions
Mode, manipulation is simple, intelligent, high-efficient, light comfortable.So the utility model effectively overcome it is more in the prior art
Practical problem is to have very high utility value and use meaning.
Above embodiment is only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.The utility model can be improved there are many more aspect under the premise of without prejudice to overall thought, for being familiar with this technology
Personage can all be carried out modifications and changes to above-described embodiment under the spirit and scope without prejudice to the utility model.Therefore,
Such as those of ordinary skill in the art is in spirit revealed without departing from the utility model and institute under technical idea
All equivalent modifications or change completed, should be covered by the claim of the utility model.
