Specific implementation mode
Below in conjunction with the accompanying drawings, the specific implementation mode of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
Before a preferred embodiment of the present invention is described, first to the automatic gear-box operation principle of large-scale dump truck
Carry out a simple introduction.
During driving, car running computer to speed, throttle opening etc. by carrying out comprehensive descision, to determine vehicle
Shift opportunity.Specifically, when being powered to two solenoid valves of F and H, then first gear transfer gear and directly has been connected
Keep off transfer gear.When being powered to two solenoid valves of C and F, then second gear transfer gear and overgear transfer gear have been connected.Also
That is, in the forward range of automatic gear-box, two solenoid valves that need to be powered simultaneously can just make vehicle carry out upshift operation.
As shown in Figure 1 to Figure 2, according to the manual shift of the automatic gear-box of the dump truck of the specific embodiment of the invention
Device includes shell 1 and the shift circuit that is arranged in shell 1.Specifically, the shift circuit includes：Power supply 34；Gear
Switch switch 11；The branch 31,32,33 and two of negative switch 12, three insert row A and B.
Preferably, a gear indicator light and two gear indicator lights are additionally provided on shell 1.
Referring to Fig.2, power supply 34 is preferably the anode and cathode terminals of Vehicular accumulator cell compensator, voltage 12V.Gear switches
Switch 11 has tri- outlets 1#, 2#, 3#.Negative switch 12 is grounded.
The first branch 31 is the power-on circuit of the shared F valves of two gear of a gear.Specifically, the anode connection of the first branch
Cathode to the+3X sockets of automatic gear-box, the first branch is connected to the -3W sockets of automatic gear-box.The second branch 32 is
The power-on circuit of one gear H valves.The anode of the second branch 32 is connected to the+2W sockets of automatic gear-box, the second branch 32
Cathode is connected to the -3Y sockets of automatic gear-box.Third branch 33 is the power-on circuit of two gear C valves.The third branch 33 is just
Pole is connected to the+1S sockets of automatic gear-box, and the cathode of the third branch 33 is connected to the -2T sockets of automatic gear-box.First
Branch 31, the second branch 32 and third branch 33 are to be connected in parallel.
Insert row A is preferably J1B interfaces, can be directly connected to gearbox.Insert row B ground connection.
Gear switching switch 11 can selectively switch on the first branch 31 and the second branch 32 or 31 He of the first branch
Third branch 33.Specifically, when gear switching switch 11 connects the outlet 1#, 2#, then+12V is provided to F the valves ,+3X of H valves
With+2W interfaces, to start a gear of automatic gear-box, vehicle carries out a gear and moves ahead.When gear switching switch 11 connection 1#,
When 3# is exported, then+12V voltages are provided to F valves ,+3X and+the 1S interface of C valves, to start two gears of automatic gear-box, vehicle
Carry out two gear move ahead.
When vehicle (excludes transmission internal mechanical breakdown and hydraulic system in the case where electric wiring scaling loss occurs for exploiting field
When failure), computer J1B insert row terminals on vehicle can be removed, changing manually for the present invention is connected to a spare gearbox wiring harness
The interface of blocking means manually controls two gear of the gear of gearbox one and the safe Shi Hui plant areas of vehicle (is not necessarily to computer, shift at this time manually
The control and connection of box and each sensor).
Meanwhile the present invention can also carry out test and identification of the gearbox without gear even gear.By the computer J1B interfaces of disabled vehicle
It removes on reconfiguration to manual gear control device, manually controls actuating vehicle, can intuitively reflect that the gear of transmission internal one or two is
No (because the wear damage of speed change box clutch piece substantially occurs in one or two gear sections of bottom gear) working properly is speed changer
Repair journey provide foundation.
It should be noted that automatic gear-box disclosed by the invention is the automatic gear-box of 3311E type trucies, it is suitable for
Most dump trucks.Only the interface of insert row is converted and just can be applied to other kinds of automatic gear-box.
The description of the aforementioned specific exemplary embodiment to the present invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the present invention and its actually answering
With so that those skilled in the art can realize and utilize the present invention a variety of different exemplary implementation schemes and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
