Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, wheel type tractor power gearshift electrofluidic control device, comprises automatically controlled shift handle, brake petal, accelerator pedal, controller, combination valve block, gear main tank, motor ECM; Described combination valve block is made up of proportional electromagnetic valve M1, proportional electromagnetic valve M2, proportional electromagnetic valve M3, proportional electromagnetic valve M4, and described proportional electromagnetic valve M1, proportional electromagnetic valve M2, proportional electromagnetic valve M3, proportional electromagnetic valve M4 control the gear of four kinds of different drive ratios in gear main tank respectively; The signaling line of described automatically controlled shift handle, brake petal, accelerator pedal is connected with controller, described controller is connected with motor ECM by CAN, described motor ECM controls engine running, and described controller is connected with combination valve block, and control combination valve block works.Aforementioned wheel type tractor power gearshift electrofluidic control device, also comprise gear odd-side, described gear odd-side is mechanical type shift-position changing mechanism, combines carry out gear shift with gear main tank.
Aforementioned wheel type tractor power gearshift electrofluidic control device, also comprises PTO clutch solenoid valve, described PTO clutch solenoid valve control PTO clutch.Described controller is PLC.The model of proportional electromagnetic valve M1, proportional electromagnetic valve M2, proportional electromagnetic valve M3, proportional electromagnetic valve M4 is 2FRE6.
Controller is by gathering the signal of electric control handle, brake petal, accelerator pedal, understand the intention of driver, by CAN, motor ECM data are shared, then the control of break-make and time delay is carried out to proportional electromagnetic valve M1, M2, M3, M4 in combination valve block.
Have the gear of four kinds of different drive ratios in the main tank of gear, and in combination valve block, the power on/off of M1, M2, M3, M4 tetra-proportional electromagnetic valves corresponds to the engagement of four kinds of gears in main tank.Why have employed proportional electromagnetic valve, is the control by controller comparative example valve outlet port pressure, alleviates the impact of gearshift in power box.So just can be implemented in when not stepping on clutch, driver directly by press the button of automatically controlled shift handle, realizes the switching of gear in power box, makes to operate comfortable and convenient.
Automatically controlled shift handle labour contractor is arranged on the gear operating lever of odd-side, just realizes the speed changer gear operation that a handle completes two gearboxes.Press the gear switch that electric control handle shelves labour contractor button realizes power box, dial operating handle and realize odd-side gear switch, both combinations can convert out more gear.
Automatic gear change function of the present utility model is: after slamming braking pedal, select power box target gear, 3 grades of buttons are such as pressed, after releasing of brake pedal, power box gear can be raw to 3 grades gradually from 1 grade, automatically first engine speed can be reduced in shift process, engine speed is recovered again, until reach 3 grades after having shifted gears.Also can manually first by 1 grade, wait and to reach after suitable rotational speed again by 2 grades, be manually increased to 3 grades gradually.Otherwise downshift.
The utility model anti-stall controlling method of braking is: when driver steps on brake, Vehicle Speed declines, controller detects automatic decision engine load condition after brake signal, controller as excessive in load can cut off four proportional electromagnetic valve electric currents in power box automatically, make power box become neutral gear, avoid the vexed car of motor to stop working.
The utility model flexible shifting controlling method is by the smoothing gearshift of engine speed during adjustment gearshift.
During shift-up, engine speed of short duration reduction when shifting gears beginning, is then increased to former settings.
During downshift, engine speed of short duration raising when shifting gears beginning, is then reduced to former settings.
The of short duration change of engine speed is unfavorable to needing the application of constant power output shaft rotating speed.If need to keep power output shaft speed to stablize, driver can turn off this function.
When driver presses electric control handle one grade of button, control unit detects this signal, then judges brake signal, if releasing of brake, then power box one grade of proportional electromagnetic valve M1 obtains electric, and power box puts into first gear.Tractor travels on main tank one grade.
When tractor travels with main tank one grade, driver presses electric control handle second gear button, and control unit detects this signal, then power box second gear proportional electromagnetic valve M2 obtains electric, and power box puts into second gear.Tractor travels on main tank second gear.If at this time have selected flexible shifting function, then control unit is when detecting that driver rises second gear order, with motor ECM bus communication, control the of short duration reduction of engine speed, then solenoid valve M1 power-off, M2 obtains electric, engine speed returns to former settings again, smoothly rises second gear.
When tractor is when starting to walk, when driver directly presses electric control handle third gear button, control unit detects this signal, then judges brake signal, if releasing of brake, then power box third gear proportional electromagnetic valve M3 obtains electric, and power box puts into third gear.Tractor travels in main tank third gear.But this starting directly hangs that third gear may impact can be larger, on gearbox damage with have impact to the travelling comfort handled.If at this time have selected automatic gear change function, when then control unit detects that driver rises third gear order, after releasing of brake pedal, power box gear can be raw to 3 grades gradually from 1 grade, automatically first engine speed can be reduced in shift process, engine speed is recovered again, until reach 3 grades after having shifted gears.
To brake anti-stall function, when control unit detects brake signal, and with ECM bus communication, read engine load rate situation, controller as excessive in load can cut off four proportional electromagnetic valve electric currents in power box automatically, makes power box become neutral gear, avoids the vexed car of motor to stop working.
In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
