In like manner, when second oil hydraulic cylinder 2 shrinks, when first oil hydraulic cylinder 1 stretches, hydraulic oil begins oil extraction in the second oil hydraulic cylinder rodless cavity 22 and the first oil hydraulic cylinder rod chamber 11, left side oil circuit belongs to the oil extraction oil circuit among the figure at this moment, hydraulic oil is through first solenoid valve 8 in first oil circuit, open first one-way valve 4, hydraulic oil produces back pressure through the basic pressure regulator valve 3 in first oil circuit time, the force value of back pressure also can be regulated setting, hydraulic oil passes through the backflow oil circuit again, and open the first unidirectional relief valve 6, to the second oil hydraulic cylinder rod chamber 21 and the 12 interior repairings of the first oil hydraulic cylinder rodless cavity, this moment, the first unidirectional relief valve 6 played the effect of one-way valve, and this oil circuit is finished the basic damping function of the above-mentioned first basic damping oil circuit.
When needs increase damping, close first solenoid valve 8, hydraulic oil first one-way valve 4 and the basic pressure regulator valve 3 of flowing through again behind first pressure regulator valve 8 of can flowing through when second oil circuit circulate, 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 described 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 10 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, articulated system comprises side arm 33, after-frame 35 and left and right sides oil hydraulic cylinder, described side arm and after-frame are realized rotating by turntable bearing, the hydraulic damping system of articulated coach uses left hydraulic cylinder 41 and the right oil hydraulic cylinder 42 of symmetry each other, 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, right oil hydraulic cylinder 42 is equivalent to second oil hydraulic cylinder 2, work as Ackermann steer angle, must have an oil hydraulic cylinder to stretch, and another oil hydraulic cylinder compression.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 is subjected to tensile force and stretches out, and its oil circuit control does not repeat them here; 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 by 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 and right oil hydraulic cylinder 42 interior hydraulic oil can not continue discharge, stoped left hydraulic cylinder 41 to continue to shrink or the 42 continuation stretchings of right oil hydraulic cylinder; 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 was subjected to 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 3 twice supercharging of basic pressure regulator valve; 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 super angle locking and safety protection.
To sum up; adaptive damping of the present invention control design cushion system is ingenious, level of integration is high, compactness simple for structure, cost of production are low, easy to maintenance; good buffer effect; can play the function that strengthens damping by arranging of three pressure regulator valves, unidirectional relief valve also makes vehicle possess the function of super angle locking and safety protection.
