According to each gear arranging situation of loader, will the working condition of the R that reverse gear, neutral N, forward gear F1, forward gear F2 be illustrated one by one.As shown in Figure 3, Figure 4:
The R that reverses gear is that piston rod is released state entirely: according to the Joystick input control order, solenoid valve 10 has the electric current input, move upward after spool 9 adhesives, the 3rd suction port III and source of the gas conducting and air inlet, other suction port sealings, pressurized gas promotion this moment back piston ring 7 moves right, and main piston ring 6 drives spacers 5, secondary piston ring 4 and piston rod 1 together to left movement, contacts the back with front cover 2 to limit position to secondary piston ring 4.Interior each chamber of cylinder body this moment reaches pressure balance, realizes living, and stopper rod 1 is released range arrival R gear;
Neutral N is the action of a gear of piston rod withdrawal: according to the Joystick input control order, solenoid valve 10 has the electric current input, move upward after spool 9 adhesives, the first suction port I, the 3rd suction port III and source of the gas conducting and air inlet, other suction port sealings, this moment, pressurized gas promoted back piston ring 7 to left movement, and secondary piston ring 4 drives spacer 5, secondary piston ring 6 and piston rod 1 and together moves right, and contacted the back with cylinder body 3 front covers to limit position to secondary piston ring 4.Each chamber reaches pressure balance in this moment cylinder body, realizes piston rod 1 LAP of withdrawing left, reaches the N gear;
Forward gear F1 is an action of two sections strokes of piston rod withdrawal: according to the Joystick input control order, solenoid valve 10 has the electric current input, move upward after spool 9 adhesives, the second suction port II, the 4th suction port IV and source of the gas conducting and air inlet, other suction port sealings, this moment, pressurized gas promoted to reach the limit of the position after back piston ring 7 moves to cylinder body 3 ends left, and secondary piston ring 4 moves to left and reaches the limit of the position after front cover 2 contacts.Main piston ring 6 then drives piston rod 1 and moves right, until with reach the limit of the position after back piston ring 7 contacts.Each chamber reaches pressure balance in this moment cylinder body, realizes the piston rod two sections strokes of withdrawing left, reaches the F1 gear;
Forward gear F2 is an action of full reduced time of piston rod: according to the Joystick input control order, solenoid valve 10 has the electric current input, move upward after spool 9 adhesives, the second suction port II and source of the gas conducting and air inlet, the sealing of other suction ports, pressurized gas promoted secondary piston ring 4 and moved to left and reach the limit of the position after front cover 2 contacts this moment.Main piston ring 6 then drives piston rod 1, back piston ring 7 moves to left and moves right, until with back balance piston ring 7 with reach the limit of the position after rear end cover 8 contacts.Interior each chamber of cylinder body this moment reaches pressure balance, realizes the piston rod full reduced work that reverses left, reaches the F2 gear.
Because engineering machinery is poorly sealed in working process, usually has the air reservoir gas leak phenomenon, owing to system's air pressure deficiency, it is ineffective to brake during startup.And if the trailer reversing handle is not as for neutral when starting, and system's air pressure deficiency causes cylinder body can't get back to neutral, occurs the coaster phenomenon when then having vehicle launch probably.
As shown in Figure 1 and Figure 2: this invention increases program optimization in manipulation process at the problems referred to above, and Joystick A and execution cylinder C need place neutral gear position when at first starting.And if vehicle accident extinguishing in the process of moving, and carry out cylinder C not when neutral position, need the manual control handle place neutral gear position, gear is neutral when guaranteeing vehicle launch.This new electronic control atmospheric control mainly is divided into three parts, namely as the Joystick A of input unit, and the Direct box B of analytic unit, the execution cylinder C of performance element.Wherein: the profile of Joystick A is similar to common engineering vehicle turn signal controller, has many gears alternative, and easy for installation, replaceability is strong, use strong operability.In the Direct box B control unit is housed, vehicle could stop working when its inner input routine can guarantee that cylinder and handle must place neutral gear position, Joystick A and carry out cylinder C and need place the neutral gear position vehicle to start.If vehicle is accident extinguishing in the process of moving, and carry out cylinder not when neutral position, need manual Joystick to place neutral gear position, vehicle could start.Carry out cylinder C and then utilize electromagnetic principle and air pressure principle.Advance the break-make of each suction port by electromagnetic valve, finally realize the to-and-fro motion of solenoid valve.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the structure that can utilize above-mentioned announcement and technology contents are made a little change or be modified to the equivalent embodiment of equivalent variations, but every content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
