Working principle of the present invention is: when electromagnet is not energized and system does not provide hydraulic oil, the iron core of electromagnet is retracted mode, first spool is in left position under the effect of the first spring force, now oil suction chamber is connected by the first spool and oil back chamber H, control chamber and the oil back chamber H of the second spool right-hand member connect, second spool is in right position under the effect of the second spring force, and the guide wheel in idler positions sensing mechanism stretches out, and electromechanical control valve is in mechanical normal closed state.
When system starts hydraulic power unit, to electromechanical control valve input hydraulic pressure oil, and when being powered to electromagnet by wire and tenminal block, magnet spool obtains electric, stretch out at electromagnetic force lower core, and promote the first spool and slide into right position, hydraulic oil enters the control chamber of the second spool right-hand member by the first spool, and promote the second spool and slide into left position, second spool drives second connecting rod and first connecting rod to make guide wheel full reduced time, now hydraulic pressure oil-feed J enters the first load oil pocket P1 by the second spool, the hydraulic oil of the second load oil pocket P2 flows into oil back chamber H, thus control load is in pine stops state.
Electromagnet power-off is made when system sends skidding instruction, coil losing electricity in it, iron core reverts to retracted mode, first spool is back to left position under the effect of the first spring, hydraulic pressure oil-feed J flows into oil back chamber H by the first spool, the control chamber pressure release of the second spool right-hand member, second spool returns to right position under the effect of the second spring force, second spool drives second connecting rod and first connecting rod that the guide wheel of guide wheel position device sensing mechanism is stretched out, now hydraulic pressure oil-feed J enters the first load oil pocket P1 by the second spool, the hydraulic oil of the second load oil pocket P2 flows back to oil back chamber H, thus control load is in brake standby condition.
At brake standby condition, when supratrochlear keep plate press down one by one process each idler positions sensing mechanism on guide wheel, guide wheel promotes the second spool by first connecting rod and is moved to the left to a certain design attitude, hydraulic pressure oil-feed J is made to connect the second load oil pocket P2, the hydraulic oil of the first load oil pocket P1 flows back to oil back chamber H, thus control load implements power brake.
The present invention is connected with main second spool by the second bearing pin in the middle part of first connecting rod, and link position is by the Proportionality design controlling stroke.This valve has double input function, by high-speed double electromagnet electric control, realizes Mechanical course by connecting rod guide wheel mechanism, and automatically controlled and Mechanical course can realize and gate control logic.
