When needs increase damping, close first solenoid valve 8, hydraulic oil first one-way valve 4 and basic pressure regulator valve 3 of flowing through again behind first pressure regulator valve 31 of when second oil circuit circulate, can flowing through, the above-mentioned first supercharging damping oil circuit realize that damping regulates, and play the function of increase damping.
When 2 contractions of second oil hydraulic cylinder, when first oil hydraulic cylinder 1 stretches and surpasses the scope of setting; Close the 3rd solenoid valve 18; Hydraulic oil in the second oil hydraulic cylinder rodless cavity 22 and the first oil hydraulic cylinder rod chamber 11 can not continue to discharge; Pressure between the rod chamber 11 of first oil hydraulic cylinder 1 and the rodless cavity of second oil hydraulic cylinder 22 to the 3rd solenoid valves 18 rises rapidly, stops first oil hydraulic cylinder 1 to continue to stretch or the 2 continuation contractions of second oil hydraulic cylinder; When force value that force value is set greater than the second unidirectional relief valve 7, the relief valve of the second unidirectional relief valve 7 is opened pressure release, plays the safety protection effect; When force value is lower than the force value that the second unidirectional relief valve 7 is set, in the time of can overcoming institute and act on two power on the oil hydraulic cylinder, second oil hydraulic cylinder stops to shrink, and first oil hydraulic cylinder stops stretching, and the above-mentioned first safe locking oil circuit plays latch functions.
In 2 contractions of second oil hydraulic cylinder, first oil hydraulic cylinder, the 1 stretching oil circuit process of circulation, accumulator 20 also can play the function of repairing or oil storage.
Specifically, adaptive damping control buffer system of the present invention is applicable to the hydraulic damping system of articulated coach, and articulated system comprises side arm 33, after-frame 35 and left and right sides oil hydraulic cylinder; Said side arm and after-frame are realized rotating through turntable bearing, and the hydraulic damping system of articulated coach uses the left hydraulic cylinder 41 and right oil hydraulic cylinder 42 of symmetry each other, and left hydraulic cylinder 41 is connected side arm assembly 33 and articulated system rear cross beam 34 respectively with right oil hydraulic cylinder 42 two ends; At this moment; Left hydraulic cylinder 41 is equivalent to first oil hydraulic cylinder 1, and right oil hydraulic cylinder 42 is equivalent to second oil hydraulic cylinder 2, works as Ackermann steer angle; Must there be an oil hydraulic cylinder to stretch, and another oil hydraulic cylinder compression (as shown in Figure 2).When articulator was kept straight on, the piston of left hydraulic cylinder 41 and right oil hydraulic cylinder 42 all was in the neutral position; When vehicle turned left, left hydraulic cylinder 41 was compressed power and shrinks, and right oil hydraulic cylinder 42 receives tensile force and stretches out, and its oil circuit is controlled at this and repeats no more; Excessive when angle of turn, when need strengthening damping, the vehicle electrically controlling system outside the present invention is closed the 4th solenoid valve 19 through trigger switch, and hydraulic oil passes through basic pressure regulator valve 3 after through second pressure regulator valve 32 again, plays the effect that strengthens damping; When the angle of vehicle left-hand bend surpassed the scope of setting, automatical control system can be closed the 4th solenoid valve 19, because left hydraulic cylinder 41 can not continue to discharge with right oil hydraulic cylinder 42 interior hydraulic oil, prevention left hydraulic cylinder 41 continues to shrink or 42 continuation of right oil hydraulic cylinder stretch; When force value during greater than the force value set, the relief valve of the first unidirectional relief valve 6 is opened pressure release, plays the safety protection effect; When force value is lower than the force value that the first unidirectional relief valve 6 is set, in the time of can overcoming vehicle and act on two power on the oil hydraulic cylinder, first oil hydraulic cylinder stops to shrink, and second oil hydraulic cylinder stops stretching, plays the locking effect.This moment, locking was relative, and left hydraulic cylinder can stretch out, and right oil hydraulic cylinder can shrink this moment.Vehicle stops vehicle further to increase angle of turn, but allows vehicle to return to the craspedodrome state relatively, plays the safety protection effect.
In like manner, when vehicle was turned right, left hydraulic cylinder 41 received tensile force and stretches out, and right oil hydraulic cylinder 42 is compressed power and shrinks; When needs strengthened damping, automatical control system was closed first solenoid valve 31, through strengthening damping after first pressure regulator valve 8 and basic pressure regulator valve 3 twice supercharging; When the angle of vehicle right-hand bend surpassed the scope of setting, automatical control system can be closed the 3rd solenoid valve 18, stoped vehicle to continue right-hand rotation, played the function of ultra angle locking and safety protection.
